PROCEDURE FOR THE TREATMENT OF AN ARTICLE, AS FOR INSTANCE GLASS ARTICLE, IN A GASFLUIDISIERTEN PARTICLE MATERIAL BED AND DEVICE FOR THE EXECUTION OF THE PROCEDURE

The invention concerns a procedure for the treatment of an article, as for instance a glass article, in a gasfluidisierten particle material bed, with which fluidization gas by the particle material bed flow one leaves as well as and which is immersed articles which can be treated into the gasfluidisierte partial marriage material bed a device for the execution of the procedure. Gasfluidisierte particle material beds are used for the execution of many treatment procedures. Thus for example Metallgegenstände, like Metallbleche, can - volumes or - wires, a thermal treatment, a deterring or a starting, by immersing the same into a gasfluidisiertes particle material bed will e.g. subject. I0 it was also already suggested, glass article, how e.g. Glastafeln to link up by immersing the hot glass articles into a fluidisiertes particle material bed which on a substantially lower temperature than those the glass article is held. Heated up fluidisierte Teilchsnmaterialbetten can also for the rapid and even heating up of articles immersed in such beds be used. In addition course-like materials can, as textiles or paper are e.g. getroeknet, in the course of their production in flnidisierten particle material beds. Finally articles can be covered by immersing the same in hot condition into a fluidisiertes bed from fusible teilehenförmigen material with this material. It now found that the execution of a number of treatment procedures, with which a bed from gasfluidisiertem teilchenförmigen material is used can be improved thereby that within a local range of the bed unaufg a wirbelter, static state of the particle particle is produced. The invention is the basis the task to indicate a procedure for the treatment of an article in a gasfluidisierten Teilchenmaterialhett which makes an even and error free treatment of the article for this realization possible under utilization. This task is taken off according to invention with a procedure of the initially described kind thereby solved that to the production of a unaufgewirbelten static state of the particle particle within at least a local range] bed from this range Pluidisierungsgas. In accordance with a further characteristic of the invention it is favourable hiebei to take the gas off from the local bed range with a consolidated state of the particle particle causative throughput. One will in most cases proceed further in such a way that the gas is taken off from within the Bewegnngsbahn of the article lying local bed range. The procedure according to invention is in particular applicable to the thermal treatment of a Glastafel e.g. to thermal linking or recompensing of a Glastafel up. The invention accordingly plans a procedure for thermal linking of a Glastafel up, with which the hot Glastafel is lowered into a gasfluidisiertes Teilchenma%erialbett held on a Glasabschreoktemperatur, and which is characterized by that the gas is taken off from the upper bed range passed by the Glastafel with their entering the particle material bed. With this application of the invention, if the Glastafel by the upper bed range is lowered, in that the teilchenförmige material in a static, consolidated condition hefindet themselves, which Oherflächen of the glass of a initial gleiehmäSigen cooling subjected, which makes the Glasoberfläehe less susceptible in relation to deformation during the following refreshingly for the Glastafel in the &5 main part of the particle material bed under the upper static bed range. Another kind of thermal linking of a Glastafel up in the procedure according to invention plans that with the taking of the gas off from the upper bed range before lowering the hot Glastafel into the bed one begins, the gas taking off throughput for the gradual production of the static, consolidated state of the particle particle in upper bed bed is adjusted, and the Glastafel with its lower edge is lowered into the upper bed range at one time before full reaching of the static, consolidated condition of the Teilshenmaterials. Preferably with this procedure it is proceeded in such a way that the entire Glastafel is lowered by the upper bed range, before the full static, consolidated state of the particle particle enters this range. A kind of the execution of this procedure consists of that one takes continuously fluidization gas off from a range to both sides of the path of the Glastafel in the top of the particle material bed, while the Glastafel is lowered into the particle material bed. The invention lets itself use also for the controlling of the condition of the teilchenförmigen material within the range of an opening, by which an article enters the particle material bed. Hiefür plans an arrangement of the invention that the gas is taken off from a local range lying beside an opening in the delimitation of the particle material bed and the i0 gas taking off throughput is adjusted for the production the opening of locking degree of compression. With a kind of application of this procedure it is proceeded in such a way that the gas is taken off from a local range lying beside a vertical opening for the lateral inlet of a more plattenoder band-shaped article and the gas taking off throughput is adjusted for the production of a degree of compression permitting the passage of the article by the consolidated particle material. A further training of the invention plans that for the different treatment from parts of the article, in particular for gradated thermal linking of a Glastafel up, gas is taken off from one or more local bed ranges from, for which and/or in each case in the path only one part of the article which can be treated is appropriate (lies). In accordance with another kind of execution DOS of procedure according to invention it can be proceeded also in such a way that gas is taken off from a majority from local bed ranges, which are in horizontal distances from each other arranged and extend in the particle material bed essentially perpendicularly under allocation the same into a majority of separate parts Hiebei can in favourable way the gas from everyone of the local bed ranges with such a throughput is taken off that on the one hand the particle material in everyone is such range in one for the physical separation of the parts of the particle material bed from each other sufficiently consolidated condition and on the other hand the passage becomes certified one article which can be treated by the consolidated particle material in everyone such range and thus by a part of the particle material bed another. The invention can be consulted also for gradated thermal linking up of Glastafeln with a so-called view zone, as they come as Fahrzeugwindschutzseheiben to the use. Hiezu becomes on the basis of a procedure for abgestnften thermal linking of a Glastafel up, with which the particle material bed held on a glass deterrence temperature and the hot Glastafel vertika! into particle material bed lowered, according to invention so proceeded that the local bed ranges, from which gas is taken off are selected thus that with lowering the Glastafel the parts of the Glastafel, which in the unaufgewirbelten planned for a smaller pre-loading degree, are linked up to static state of particle particles held to contact and the parts of the Glastafel lying between this Bereiehen by contact with whirled up particle material in higher degree, whereby a Glastafel with strips from less linked up glass is produced alternating with strips from more strongly linked up glass. With another type of the according to invention of the procedure, with which an article is promoted by a range of the particle material bed to another range, the invention plans that gas of two vertically it erstreekenden itself parallel enriches the particle material bed is taken off, which such a distance exhibits that particle material between dies.en ranges itself in a unaufgewirbelten, consolidated condition finds, which enriches gas taking from one off of these ranges for one for the re-establishment of the Aufwirbslung of the particle material within this range and between these sufficient length of time during continuation of the gas taking from the other range is interrupted and then the gas taking from a range for resetting the unaufgewirbelten, consolidated state of the particle particle between these ranges is reconvened. Because of the higher pressure, which prevails at the basis of the particle material bed compared with the pressure in the upper parts of the bed, a grö1 erer gas taking off throughput at the basis of the bed can appear as within high-lying bed ranges, what for the production of a range from in a unaufgewirbelten, that could lead static condition particle material present at the basis the best is broader than in the upper parts of the bed. In order to avoid this, it can be proceeded appropriately in such a way that gas is taken off from the ground everyone of the vertical ranges of the particle material bed with higher throughput than from the top of this range. A device for the execution of the procedure according to invention covers a container for the gasfluidisierte particle material bed as well as a mechanism to the Hindurchleiten of fluidization gas by the particle material and is according to invention thereby marked that in the container a mechanism for taking from gas off from at least a local range of the Teilchenma£erialhettes for the production of a unaufgewirbelten, static state of the particle particle in this range intended is. The gas taking off mechanism exhibits preferably at least a gas taking off line arranged apart from the local range. Further the arrangement can be so met during a device, which possesses a mechanism for moving one article which can be treated along a course in the container, that the local range of unaufgewirbelten static particle material produced by the gas taking off mechanism lies in the path of the article. 2e in accordance with an appropriate Ansführungsform of the device according to invention can be intended that the gas taking off mechanism two oblong, each other turned gas taking off lines under mutual distance in the container to the delimitation of a path for an article between them to exhibit, which is attached for taking from gas off from the range of the particle material bed between the gas taking off lines. After a further characteristic of the invention thereby the gas taking off lines can be horizontal in a top of the container and appropriately parallel to each other arranged. In another execution form of the device according to invention it is intended that the container with a vertical opening for the inlet one is trained into the container article which can be treated and the gas taking off mechanism is installed in the container beside the vertical opening. In such a device the gas taking off mechanism exhibits appropriately two oblong gas taking off lines, which are installed each other turned to both sides of the opening under delimitation of a course for article between the gas taking off lines, an entering the container. After remark variation in type it is intended that the gas taking off mechanism exhibits a pair of parallel gas taking off lines, which are perpendicularly in the container under mutual distance to the delimitation of a course for the movement of an article of a part of the container on the other hand installed. A further training of this execution form consists of that the gas taking off mechanism exhibits two pairs of parallel, vertically gas taking off lines installed within the range, which are arranged pairs by 0 lines under mutual distance and which have lines of each pair a mutual distance to the delimitation of a course to the movement of an article in the container. In another execution form of the device according to invention the arrangement can be so met that the gas taking off mechanism exhibits a majority of gas taking off lines, which extend 5 under mutual distance vertically in the container for taking from gas off from a majority from local ranges in the course of the article. The gas taking off lines can be vertical first and second numbers of parallel, gas taking off lines installed in the container, whereby the gas taking off lines are arranged in the two rows each other turned and in mutual distance to making a vertical inlet of an article possible between the two rows. S0 everyone of the vertical gas taking off lines can be vertically divided into chambers, whereby with each chamber a separate gas taking off pipe is connected. Below the invention is more near described on the basis of remark examples illustrated in the designs. In the designs show: Fig.l a Perspektivansicht a gasfluidisiertes particle material bed of containing container with two gas taking off lines for the delimitation of an entrance course for articles into the partial marriage material bed, Fig.2 a plan view of the device after Fig.1, Fig.3 a partly cut front view of the device after Fig.l, Fig.4 a detail on average after the line IV-IV in Fig.1, Fig, 5 a schematic representation of a Gasabzieheinriohtung for the enterprise of the device after Fig.l, Fig.6 a diagram for the representation of the enterprise of the device after Fig.l on use of the gas taking off mechanism after Fig.5, Fig.7 a Perspektivansicht of an end of a second execution form of the device according to invention for the representation of two beside a vertical opening in a Endwand, which can be treated arranged in the top of the container under mutual distance, i0 one Container for a particle material bed arranged vertical Gasabzlehleitungen, Fig.8 a partly cut Endansich.t of the device after Fig.7, Fig.9 a partial section of an alteration of the device after Fig.7, Fig.10 a Perspektivansicht of a third remark example of the device according to invention with representation of two pairs from vertical in a container containing a particle material bed ang gas taking off lines, Fig.ll a partial section Is eordneten after the line XI-XI in Fig.1O, Fig.12 a Perspektivansicht of a fourth remark example of the device according to invention with representation of two Beihen gas taking off lines arranged containing a particle material bed from vertical in a container for the delimitation of an entrance course for Glastafeln. into the particle material bed between the two rows from lines, and Fig.13 a partial section after the line XIII XIII in Fig.12. The Fig.l to 4 illustrates schematically a deep tub --i--, those as containers for a gasfluidisiertes particle material bed --2-- serves, which can be held in a calm, evenly expanded particle fluidization condition. The teilchenförmige material can be for example a y-alumina with an average partial marriage size of 64 pm and a number density of 2,2 g/cma. The material is whirled up by an upward stream of a fluidization gas, which is usually air, whereby the flow rate amounts to for example 0.54 cm/s and the upward stream evenly over the basis of the particle material bed of the top side of a porous diaphragm --3-- from a memory chamber --4-- at the ground of the container takes place. A high decrease of pressure by the diaphragm --3-- the maintenance of the calm state of the particle material particle promotes --2-- for applications like the thermal treatment of hot Glastafeln, if such a state of the particle material particle is desired. The container is on a Hebetiseh be installed, SE that it into a position for the admission of a heii3en curved Glastafel be raised can, which ven vertically a not represented bending station for thermal pre-loading by deterring in the particle material bed is lowered. The fluidisierte teilchenförmige material stretches sees upward over essentially the entire depth of the container --I-- out. The surface level of the particle material bed is --6-- straight under the upper edge --5-- the container suggested. If one links boards up from soda lime silicic acid glass thermally, the Glastafeln on a temperature can be within the range of 0,610 to 680°C, and the temperature of the whirled up material is appropriate üblioherweise within the range of 30 to 150°C, for preferably about 60 to 80°0. If the hot Glastafel into the fluidisierte teilchenförmige material in the container --i-- , arises a very strong Bührwirkung is lowered on the teilchenförmige material at the surfaces of the Glastafel. This agitating effect can be to due to the emergence of thin Gasfilmen at the surfaces of the Glastafel. At the surface of the partial marriage material bed the Gasfilme break open into channels, so that an uneven initial cooling of the eberflächen Glastafel can occur, if this hindurGhtritt by the top side of the particle material bed. Such a uneven initial cooling of the surface of the gas board cannot lead acceptable loss at optical quality of the glass board surfaces under certain circumstances to one any longer. This difficulty lets itself now erfiudungsgemäß thereby to avoid that gas from range of the particle material bed, which the Glastafel passes through with the entering the bed with such Durehsatz is taken off from the upper that the teilchenförmige material in a static, consolidated condition, contacting the Glastafel within this range, is held, w hrend the Glastafel by this range is lowered. In such a way produced unaufgewirbelte, static layer of the particle material bed exposes the surfaces to the Glastafel of a initial even cooling, while the Glastafel is lowered by this range and s the fluidisiezte particle material bed enters. In order to plan this unaufgewirbelte, static layer within the upper range of the fluidisierten bed, the teilchenförmige material within the range, which extends downward from the top side of the bed, is defluidisiert. In the container a Gasabziebeinrichtung is installed, the gas taking off lines --7 and B-- enclosure, which are arranged each other turned in such a situation that them itself straight under the surface level --6-- the fluidisierten bed find. The Gasabziehieitungen --7 and 8-- have a mutual distance to the delimitation of one for example 125 mm broad entrance course --9-- for the Glastafeln and are arranged thereby apart from the too defluidisierenden local range of the bed. Each of the gas taking off lines --7 and B-- has a middle main part --10--, an LS L-shaped channel body --I1-- exhibits (Fig.4). A micro-porous woven wire net --12-- is at each channel body --11-- under education of a wall pointing inward --lg-- and a diagonal wall --14-- the gas taking off line --7 or 8-- fastened. A suitable micro-porous woven wire net material is available in the trade. It has an multilayer structure stainless steel wire net woven by situations from, whereby the situations are sintered together, and a permeability for air of 97,3 1/s/mZ with a difference of pressure of 1 kPa. Each gas taking off line --7, 8-- has wing parts --15--, those of same structure as that of the center section --10-- and at the ends of the center section --I0-- by hinges are attached. By adjusting the angle of the wing parts --15-- relative to the center sections --10-- the Gasabziehleitun2s towards --7 and 8-- can these be adjusted in such a way that approximate to orm the curved Glastafeln which can be linked up, are adapted. After a remark example are the gas taking off lines --7 and 8-- 50 mm deeply, 25 mm wide and of an overall length, which is that equal to the Glastafel, e.g. 2 m for a windshield. During this arrangement are the gas taking off lines --7 and 8-- in a depth of 50 mm below the surface level --B-- the fluidisierten bed attached. A branched bore --17-- connects the center section --10-- and the two wing parts --15jeder gas taking off line with a collecting line --eat--, those to a vaccum pump --19-- leads, like Fig. 2 shows. Becomes to the Gasahziehleitungen --7 and 8-- by means of the vaccum pump --19-- Negative pressure close-put, becomes fluidization gas of the range between and over the gas taking off lines --7 and 8-- by from the micro-porous wire net --12-- formed walls of the gas taking off lines sucked off, and that teilchenförmige material in the top of the fluidisierten bed one defluidisiert, in order to create by suppressing an upward escaping of fluidization gas a static, consolidated range of the teilchenförmigen material, by which the hot glass enters the fluidisierte bed. Suction force put on is steered in such a way that the component density of the particles in such a manner is that the hot Glastafel can penetrate the static, consolidated teilehenförmige material without each deformation of the Glastafel. During the descriptive special arrangement one found the creation one to a Gasabziehdurehsatz of 1,25 1/s/m length of the GasabziehIeitungen --7 and B-- 4s of prominent suction degree as suitable, which resulted in a static, consolidated layer of approximately 120 mm of depth, which could be penetrated by the lower edge of the Glastafel easily. For the best results it is however preferred that the compression of the static layer should be larger than that one, which can penetrate the Glastafel freely. This lets itself reach by that one begins with a fluidisierten bed, without suction force to the GasBe taking off lines --7 and 8-- is put on, if the hot Glastafel is ready for lowering into the fluidisierte bed. Before beginning of lowering the Glastafel into the fluidisierte bed negative pressure becomes to the gas taking off lines --7 and B-- put on, in order to begin a taking from Oas off from the upper Bettbereioh. The gas taking off throughput is adjusted, in order to produce a static compression condition of the teilchenförmigen material in upper bed bed. The final compaction condition reached in the teilchenförmigen material is more highly higher as in the previous example and than that, with which the lower edge of the Glastafel could penetrate easily the bed surface. The lower edge of the Glastafel reaches the bed surface --6-- at a time after beginning of the gas taking, which is so selected that the lower edge of the Glastafel depresses through the upper range before complete reaching of the final consolidated condition and the teilchenförmige material in upper bed bed achieved a partial consolidated condition, so that the lower edge of the board can penetrate easily the upper mad of the bed. At this time the teilchenförmige material at the upper end of the bed can being even in a smaller compression condition than, which was used in the previous example, so that the entrance of the lower edge of the Glastafel is made easier by the top of the bed. Preferably the Glastafel is lowered by the upper range n the fluidisierte bed, while the Verdiehtung of the teilchenförmigen material in the top of the bed is gradually increased, and dl6 Glastafel completely into the fIuidlsierte bed is lowered, before the teilchenförmige material in the top of the bed finally achieves its completely consolidated condition. Fig.5 points a Gasabzieheinrfchtung to the controlling of this mode of operation. The vaccum pump --19-- is with the gas taking off lines --7 and 8-- by the collecting line --18-- connected, the one main single solenoid valve --2Q--, an adjustable control valve --21--, a flow meter --22-- and a filter unit --23-- contains. A pneumatically operated control valve --24-- is over a Schleifenleitung --23-- parallel to the control valve --21-- switched. The part of the collecting line --18-- between the vaccum pump --19-- and the main single solenoid valve --20-- a branch line has --26--, those by a secondary single solenoid valve --27-- to the atmosphere leads. If lowering a hot Glastafel is begun, a not represented BegrenzungsschaIter is operated, that the main single solenoid valve --20-- and the secondary single solenoid valve opens --27-- closes. The manipulation of the limit switch starts also a tail unit --28--, that the retarded enterprise of the control valve --24-- steers. As is shown in Fig.6, becomes with opened main single solenoid valve --20-- and closed control valve --24-- Gas initially of the upper range of the fluidisierten bed by the Gasab3e drawing lines --7 and 8-- with a constant throughput of approximately 1 1/s/m length of the gas taking off lines --7 and 8-- taken, how is adjusted by the extent, in that the control valve off --21-- is opened. This condition remains existing a partial degree of compression for 20 s, as by the horizontal part of the curve A-B is suggested, at the end of this time the teilchenf5rm2gc material in the top of the bed reached, and the timer --28-- then the all3s solves the mähliche opening of the control valve --24-- out. If itself the control valve --24-- gradually, arises an appropriate gradual rise of the taking off throughput of the Fhidisierungsgases of the upper range of the bed, until approximately 37 opens s a maximum gas taking off throughput of for instance i I/s/m length of the taking off lines --7 and 8-- is reached. This time the control at the control valve becomes --24-- turned around, around the valve --24-- to close, the single solenoid valve --20-- , and the single solenoid valve is closed --27-- one opens. The lower edge of the Glastafel steps C into the top of the bed at present on the curve after Fig.6, i.e. 7 s after beginning of opening the control valve --24-- . At this time the upper range of the bed will be further consolidated, however is the degree of compression still in such a manner that under edge of the Glastafel easily by the surface of the bed can penetrate. The Glastafel depressed completely through the bed surface at present D, i.e. 2 to 4 s after entering the lower edge of the Glastafel into the top of the bed, dependence on the depth and the lowering speed of the Glastafel. In the time period between C and D on the curve the material achieved in upper bed bed a higher degree of compression than, which permits the free entering of the lower edge of the Glastafel through don top of the bed, which degree of compression for the optical quality of the glass is however more favorable, as errors of the hot surface of the Glastafel are kept as small as possible. At the beginning of preset 0ffnungsgrad of the control valve --21-- determines the initial - 8 - Nr.ä71081 gas taking off throughput of the upper bed range, as is represented by the part of the curve A-B in Fig.6. The rate and the extent of the opening of the control valve --24-- determines the rise rate of the gas taking and the resul% Œ ezenden maximum Gasabziehdurohsatz, and the conditions are stopped depending upon the needs concerning any special finished type of glass, e.g. regarding the thickness and temperature of the glass. With application of the above procedure boards from soda lime silicic acid glass were lowered by 2.8 mm of thickness after the bend for the form of a Fahrzeugwindschutzscheihe and with a temperature of 660°C into a bed from y-Aluminiumoxydteilchen with a speed of 300 mm/s. The bed was on a temperature of 600C. Each in such a way produced linked up Glastafel had a central tensile strength within the range of 38 to 42 MPa, and no unacceptable distortion in the Glastafeln resulted. The procedure of the production of a static layer of teilchenförmigem material within the upper range of a fluidisierten Teilohenmaterialbettes for the use for linking up Glastafeln has a supplementing advantage, if one another Fluidlsierungsgas than air, e.g. Helium, uses. Helium has a higher heat conductivity than air and produces one-more rapid cooling of a hot Glastafel immersed into the fluidisierte bed, what leads to a higher pre-loading degree of the Glastafel. However such fluidization gases are expensive such as helium, and one cannot let them escape simply as waste. The procedure according to invention made possible, the gas, which is taken off from the top of the particle material bed, kont nuierlich by the bed with only small losses in the circulation to lead. The procedure is applicable also with the enterprise of fluidisierten beds, which use poisonous or otherwise dangerous fluidization gases or which in the enterprise to the production such gases lead. An example hiefür is the use of a fluidisierten bed from organic teilchenförmigen material, which is used for the dipping covering hotter, into the bed of immersed articles. Such fluldisierte beds produce poisonous gases due to the decomposition of the organic Oberzugsmaterialisn with heating up, and such gases can be removed by taking the fluidization gas off from the top of the bed surely. It can be necessary to plan an inlet for the articles into the flnidisierte bed in other way than by the static layer from teilchenförmigem material at the top side of the bed. That further down on the basis the Fig.7 and 8 descriptive procedures with lateral entering of articles fluidisiert an s bed would be hiefür suitable. Another possibility of the application of such a static layer from teilchenf6rmig8m material in the top of a fluidisierten bed results regarding the avoidance of escaping light teilchenförmigen material or, if the teilchenförmige material contains a portion of light fine particles. For the achievement of a high production throughput it is desired that the container --l-- as fast as possible one lifts and one lowers. Around burying teilchenförmigem material over the upper edge --5-- the container during lifting and lowering to avoid, gas can by the gas taking off lines --7 and 8-- to the Defluidisierung of the upper range of the bed &0 during Hebeund guidance procedure to be taken off. The Fig.7 and 8 veranschanllchen a container --I--, into a gasfluidisiertes particle material bed in a calm, evenly expanded particle fluidization condition in the way described on the basis the Fig.l to 4 to be held can. In the device after Fig.7 and 8 a Endwand asked --30-- the container --I-- one verti &s kale schlitzförmige opening --81--, those for the lateral entrance of articles by the opening --31-- into the Teilchenmat8rialbett is intended. A pair gas taking off lines --7 and 8-- are vertical in the container --I-- beside the vertical opening --81-- and the Endwand --30-- to both sides of the lower end of the opening --31-- arranged. Each of the gas taking off lines --7 and 8-- point an u-shaped channel body --II-- up. Each other turned open sides of the channel bodies --IL-- are in each case with a layer from micro-porous woven wire net --12-- taken off, whereby a homogenous material as used during the arrangement after Fig.l to 4 is suitable. Each of the gas taking off lines --7 and B-- is with a gas taking off pipe --17-- connected, and if negative pressure to the gas taking off lines --7 and 8-- by bore --17-- , becomes usual fluidization gas, air, is put on from between the gas taking off lines beside the lower end the opening --31-- taken off from lying bed range, whereby the teilchenförmige material within this range defluidisiert it is consolidated and to a unaufgewirbelten, static condition. The teilchenförmige material beside the top of the opening --31-- over the gas taking off lines --7 and 8-- , there its supply at fluidization gas is defluidisiert likewise and consolidated by the compression of the teilchenförmigen material in lower bed bed between the gas taking off lines --7 and 8-- becomes closed. Thus the DefluidJsierung secures a sufficient compression of the teilchenförmigen material for the catch of the opening --31-- and to preventing 1 of escaping the teilchenförmigen material from the container --I-- by the opening --31--. At the gas taking off lines --7 and B-- influencing suction force is steered, in order to produce the degree of compression in the teilchenförmigen material, which locks the opening, however in such a manner is that an in particular plattenoder band-shaped article by the opening --31-- and afterwards easily by the layer of the static, consolidated material beside the IS opening --31-- into the main part of the fluidisierten bed for treatment in the bed to depress can. With a fluidisierten bed from porous 7-Aluminiumoxyd, how it became to besohriehen above for use in the device after the Fig.1 to 4, gas taking off lines of 2,5 cm2 became cross section, 16 cm length and a distance of their surfaces from 10 cm with a Gasabziehdurohsatz of between 0,76 and 0,86 1/s/m length of the gas taking off lines --7 and 8-- used. One obtained so a range of static teilchenförmigen material of suitable dimensions and suitable degree of compression, that for the catch of the vertical s “hlitzförmigen opening --31-- was sufficient. A homogenous vertical opening with associated gas taking off lines can in the opposite Endwand of the container --i-- to leading the article out from the container intended its. In the case of use after Auordnung the Fig.7 and 8 knows the range from verdichtetcm, teilchenförmigen [4aterial, that beside the opening --31-- is produced, a wedge form of larger cross section at the basis of the bed and smaller cross section in the top of the bed assume. This comes along, because a lateral entering of fluidization air the top of the range over the upper end of the gas taking off lines --7 and 8-- to take place can. This effect lets itself keep extremely small by use of the alteration of the device, as it is shown in Fig.9. The gas taking off lines --7 and 8-- extend downward over the full depth of the bed and are into a number from vertical arranged chambers --33-- by means of the transverse walls --34-- subdivided. Each of the chambers --33-- its own gas taking off pipe points --35-- up. To the pipes --35-- negative pressure put on is steered separately in such a way that the air taking off throughput from the chambers --38-- from the lower to the upper chambers--33-- in the gas taking off lines --7 and B-- sinks. This mode of operation leads to the production of a defluidisierten range from essentially identical cross section apart from the full length of the opening --31--. The partitioning of the vertical gas taking off lines --7 and 8-- in chambers also that avoids an effect, by that the fluidization gas, with high pressure of the basis of the flnidisierten bed by the lower parts of the Gasahziehleitungen --7 and 8-- one takes off, into the top of the bed by the upper ends of the gas taking off lines --7 and 8-- one rüekgeführt. After a remark example the Gasabziehlei%ungen possesses --7 and 8-- during the arrangement after Fig.9 Querschnit% of 2,5 cm and four individual chambers --33-- of 15 cm length. With a distance of each other turned surfaces of the gas taking off lines from i0 cm one found that to the achievement of a defluidisierten range of even cross section over the full height of the schlitzförmigen opening --31-- in a fluidisierten bed from the 7-Aluminiumoxyd the necessary Gasabziehdurchsä%ze 5 to 6 i/min for the ground chamber, described above --33-- in the gas taking off lines --7 and 8--, 4 to 5 i/min for the next chamber --33--, 3 to 4 i/min for the third chamber --33-- and 0 to 2 i/mln for the upper chamber --33-- amounted to. It was found that under certain circumstances the upper chamber --33--, if desired, can be omitted. - I0 - Nr.371081 this remark example of the invention is particularly suitable for the Durchffihrung by procedures, with which in the fluidisierten bed more plattenoder band-shaped material is treated. For example a hot Glastafel, which is to be linked up by deterring in the bed, at its upper edge can hung up and horizontal into the bed by the Seitenöffnung --31-- are promoted. The device after Fig.7 and 8 is also for thermal treatment, e.g. for starting, from Metallblechen and for drying course-like materials, like paper or textiles, by continuous would e.g. drive through a Materialbahn the fluidisierte bed between at both sides of the container arranged roles and/or rollers suitably. The Materialbahn steps into the fluidisierte bed by the consolidated material beside the opening --31-- in a Endwand --30-- the container --1-- and the bed leaves by the consolidated material beside the not represented homogenous opening in the opposite Endwand of the container. Another AüsführungsbeispieI of the invention is represented in Fig.10 and 11, the gasfluidisiertes particle material bed containing container --1-- exhibits. Two pairs of gas taking off lines divided into chambers --7 and 8-- homogenous structure as the gas taking off lines --7 and 8-- after Fig.9 are vertical in the center of the container --1-- installed and exhibit a mutual distance. A vertical partition --36-- extends between each of the gas taking off lines --7 and 8-- and the appropriate long side wall --37-- the container --In. If negative pressure to the gas taking off line -7 and 8--by particulars, with the chambers: - 33: in the gas taking off lines --7 and 8-- connected gas taking off pipes --35-- , becomes fluidization gas of the range between the pairs of gas taking off lines is put on --7 and 8-- taken off, and the teilchenförmige material within this range is defluidisiert and under formation of a wall --38-- from consolidated, teilehenförmigen material, those consolidates the fluidlsierte bed into two separated parts --39 and 49-- subdivided. The gas taking off lines --7 and 8-- can the same dimensions exhibit, how they were described for the example after Fig.9, whereby of the same 7-Aluminiumoxyds the gas taking off throughput when using individual chambers --33-- the gas taking off lines --7 and 8-- also the same is, which was described at volume of the Fig.9. This arrangement makes the Zweistufenbehandiung of an article, e.g. for a Glastafel possible, in the two separate parts --39 and 40-- the fluidisierten bed. For example the part can --39-- the bed on a sufficiently high temperature, e.g. 750°C, for heating a Glastafel up on a temperature suitable for linking up its, and the hot Glastafel becomes then from the part --39-- by the wall --38-- from consolidated teilchenförraigen material for linking the Glastafel up into the part --40-- the bed promoted, which is held for e.g. 60 to 80°C on a temperature suitable for the starting from fright of the hot Glastafel. The presence of the wall --38-- from consolidated, the two parts --39 and 40-- the fluidisierten bed separating teilchenförmigen material makes also different kinds for the fluidization possible in the two parts --39 and 40-- the bed. The part --39-- the bed can in brodelndea fluidization condition using fluidization gas heated up be held, in order to obtain a rapid heating of the Glastafel. The part --39-- the bed can heating elements also elngetauchte contain, whereby the bubbling fluidization condition increases heat transmission rate between the Heizelemeuten and the teilchenförmigen material of the bed. The teilchenförmige material in the part --40-- the bed can be held in a calm, evenly expanded Te lchenfluidisierungszustand, as it is suitable for linking the Glastafel up better. That would drive a hot Glastafel through the partition --38-- from consolidated, teilchenförmigen material pushes material from the wall, which perhaps to a partial break-through between the two parts --39 and 40-- the bed to lead can. This becomes by Erse innovation of the wall --38-- in suitable time intervals avoided. One reaches this by switching off to a first pair of the gas taking off lines --7 and 8-- negative pressure put on, so that the teilchenförmige Materia! within the range of this pair by gas taking off lines and in the two pairs the Eereiah separating from taking off lines is fluidisiert, the negative pressure becomes then to the gas taking off lines --7 and 8-- again put on, around the part of the wall --38-- to renew within the range of these gas taking off lines. While this takes place, the negative pressure at the second pair of the gas taking off lines becomes --7 and 8-- maintained. If the part of the wall --38-- between the first pair is restored by Gasabziehleltungen, becomes to the second pair of gas taking off lines --7 and 8-- negative pressure put on switched off and then again put on, around the part of the wall --38-- to renew within the range of the second pair from gas taking off lines to. The whole of the consolidated wall is restored in such a way. During the arrangement after Fig.10 and 11 vertical, schlitzförmige openings with associated vertical gas taking off lines in the Endwänden of the container for the lateral entrance I0 and withdrawal into those and/or from the particles can --39 and 40-- the bed to be planned, how became on the basis the Fig.7 and 8 beschriebep. Remark variation in type of the invention is illustrated in the Fig.12 and 13. In this remark example are first and second rows --41 and 42-- of parallel gas taking off lines --43-- vertically in a container containing a fluidäsiertes particle material bed --I-- installed. Those off gas-take] eitungen --43-- in each of the rows --41 and 42-- are arranged under distances to making a vertical entrance of a Glastafel possible between the rows. Each of the gas taking off lines --43-- in the first row --41-- is an appropriate gas taking off line in the second row --42-- turned. As Fig.13 shows, each gas taking off line points --43-- an u-shaped Kanalkerper--44-- up. The open side of each channel body --44-- is micro-porous wire net woven by a layer from --45-- covered. The gas taking off lines --43-- have final closing panels --46-- and are in each case by transverse walls --4B-- into a number of chambers --47-- subdivided. Individual gas taking off pipes --49-- are with the chambers --47-- the Gasabziehleituugen --43-- connected. To each chamber --47-- the gas taking off lines --43-- negative pressure is applied, around Pluidisierungsgas by the ranges between each pair by each other turned gas taking off lines --43-- in the two rows --41 and 42-- to take off from gas taking off lines, so that the teilchenförmige material within these ranges of the fluidisierten bed in one not fluidisierteu static condition and in vertical volumes --50-- is consolidated. The gas taking off lines --43-- can a cross section of 2,5 cm2 exhibit, whereby the individual chambers --47-- a length of 15 cm have. The two rows --41 and 42-- of gas taking off lines --43-- exhibit a mutual distance of 7,5 em. In the case of use of a particle material bed out - alumina are geeingete gas taking off throughput 5 to 6 l/min. of the ground chamber --47-- the gas taking off lines --43--, 4 to 5 l/min. of the next chamber --47--, 3 to 4 i/min of the third chamber --47-- and up to 2 I/min of the upper 3 chamber --47--. A hot Glastafel which can be linked up --51-- becomes into the fluidisierte bed between the two rows --41 and 42-- of gas taking off lines --43-- lowered. The parts of the Glastafel, those of the vertical volumes --50-- to not fluidisiertem material between each other turned pairs of gas taking off lines --43-- , in a smaller extent are cooled and experienced from there a smaller pre-loading degree than the parts of the Glastafel, those are contacted of between the volumes --50-- from defluidisiertem material existing, fluidisierten teilchenförmigen material to be contacted and consequently into higher degrees be linked up. In such a way received linked up Glastafeln lift vertical volumes of less linked up glass, which alternate with volumes of more strongly linked up glass within the range not subjected to the numbers of the gas taking “s lines. For example one found that it by deterring a 3.0 mm thick board from soda lime I< Ieselsäure glass for the use as vehicle windshield, which was on a temperature of 660°C, was possible, to produce in the board a Siahtzone from volumes of smaller linked up glass with a central tensile strength within the range of 33 to 39 MPa alternating with volumes from more strongly linked up glass with a central tensile strength within the range of 47 to 49 MPa. With the break of the windshield, e.g. by falling rocks, the more strongly linked up parts of the windshield break into small, not-long-oath-end particles, while the volumes of less linked up glass in the windshield break into large pieces, which leave a certain remainder view possibility by the view zone, whereby driving the vehicle is made possible, until the windshield can be replaced.
