Verfahren und vorrichtung zum zuführen von holzschnitzeln in ein silo

The available invention concerns a procedure and a Vorrichttmg to the Zufllhren of wood shreds into a wood shred silo. The task of the procedure and the Zufiihrvorrichttmg is it to eliminate the problems arising with that well-known procedure WAD the Zufiihrvorrichtungen to the Durchfiihnmg of the procedure. Such problems are among other things the wall ring yon exhaust gases from a silo emgegen the Zuffihrdchtung of Holzschnitzein in traps, in which the Holzsclmitzel is treated to its Erw Tnung in the silo with steam or process gases. Also making dust Holzschnitzein whale trend of the Ftillvorgangs of a silo causes problems with the well-known devices, since also the staff can unhindered against the direction of travel of Holzsehnitzeln wandem. Problems arise aueh if the supply of Holzsehnitzeln for example by means of one see wesentlieh effected into a ZuftihrOffnung erstreekenden SelmeekenRirderers. The Selmeekenf6rderer works on sees typiseh in such a way, class in the top of the F6rderers a free area remains, which permits the migration yon against exhaust gases and dust the Transportdehtung. The Holzsehnitzel is umgesehtittelt aueh by the Selmeekenf 6rderer (turned and turned), so that they do not form a firm mat for k6imen. In order to eliminate this problem, became vorgesehlagen, to arrange at the discharge end of the Setmeekent2Jrderers a Ansehlagldappe to which see with a Unterbreehung of the Holzsehnitzelstrorns versehliel3en should. A ZttfOhrvorrichtung which is based on this principle is in the US-Patentsehrift 5.766.418 besehdeben among other things. In the function of the Sehliel3klappe jedoeh lack were determined. The Schliel3vorgang was nieht zuverl sig, and with the enterprise against the Zuftihrriehtung geriehteter discharge was beobaehtet. A further M6gliehkeit to use a Setmeckenf'6 more rderer is that the Holzsehnitzelstrom at the discharge end is throttled, in order to form a Holzsehnitzelpropfen. Jedoeh Besehltdigungen of the Holzsehnitzel warden beobaehtet, those the spiiteren Aufsehluss or beating beeintriiehtigen. oo °o oooo oeoo oo oo """ 2 "" i ": '-!: : : oe e o °o oee ee Go for the removal of Staubund exhaust problems also gef a icherter Zufiihrer became as Zufithrvordehtung yon Holzsehnitzeln in a Holzschnitzolsilo whom DOT. With these devices the problem arose; that Holzschnitzol and with the wood shreds mitgefiihrte Fremdstoff¢ VerschloiBe cause A, which remain existing the aforementioned Problemo to the Leek of the devices Fdhren, thus class. Wurd¢ determined, class with a erfmdungsgemligen procedure and a Zufiihrvordchtung to the Durch_Rthnmg of the procedure stromaufwartige Str6me of the wood shred supply besoitigt werdon could do. Vorfahronsgem e the approach trod the Vordehtung to their Durchfiihrung verursachon also no problems with the zuzufiLhrenden Holzsehnitzeln. To the Durchfiihnmg crfindungsgcm cn of the Verfahrcns out zuzufiihrendcn wood shreds wescntlich horizontal vorwtlrts bewcgend an f Propfen gcbildct itself, which the cross section of the progressive movement area fail, preferably more tiber a wesenfliche Ltinge of the progressive movement area. The Holzschnitzelpropfen becomes out stogweise the VorwErtsbewegung forced wood shreds gebild and auffeehterhaltela, whereby the distance erzwungencn of the Vorwartsbewegung extends jcweils to cinch part of D Ltinge of the Fortbcwegungsraums. With diescr approach it is erreieht that dcr Propfen moves rim " in Zufiihrdchtung vorwarts if the thrust means zuzufiihrcndc wood shreds enter, which move the Propfen vergrSgem and the Vergr SBerung accordingly in Zuffihrrichttmg vorw Lrts. Werm the river of the entering Holzselmitzel for any reason in the stagnation comes, stops the Holzschnitzelpropfen due to the way remaining of the stoBweisen Besehickungen. The Holzsehnitzelpropfen formed in the progressive movement area serves then however to prevent a Riickstr6mung yon exhaust gases. The Besehickungsvorgang sets sees away, as soon as the Holzsehnitzelstrom returns into the thrust means. The stoBweisen Beschiekungen for the production of a Holzschnitzelpropfens in dern progressive movement area k Srmen as one would unit-borrow Beschiekung to be formed, to their transverse longing CCIT wesentlieh the transverse longing CCIT of the progressive movement area corresponds. Altemativ IO oQoo 0000 oo oo k6nnen the filling seats as several, fibre the cross section of the Fortbewegungsraurns distributed fillings to be formed, which advantage-has at least partly asynchronously in Zufithrrichtung vorw xts movable is. In this connection is the vorgenarmte, wesentlieh horizontal Vorw - to lay out 'tsbewegung the Holzschnitzelpropfens in the relatively broad sense, head ichlich around a ausschlieBliche force of gravity movement auszusehlieBen. The Fortbewegtmg katm, con the horizontal plane something falling or rising its, in order to cause one to the Erzeugtmg of a necessary Diehte of the Propfens n6tigen kinetic resistance. Tr tgt aueh L selfunderstanding-borrowed tnge of the progressive movement area to kinetic resistance ausgetibten on the Propfen. The basic elements of the Vorriehtung consist mfindenden Eintrittsan of a transportation channel trod one into an end of the transportation channel chluss as well as one of the gegentiberliegenden end of the transportation channel into a wood shred silo fiihrenden withdrawal connection. Zwisehen this Ansehliissen points the transportation channel a given L [tnge up, those at least into the same Gr613enordnung lies as the respective Durchrnesserdimension of the entrance connection and the withdrawal connection. To the Erzeugtmg of a Fortbewegtmg of the wood shreds from the Eintrittsansehluss to the Austrittsansehluss of the transportation channel Befdrdertmgsmittel are arranged in the transportation channel. Gema6 the characteristic characteristics of the invention are designed this Befdrderungsmittel as slidegate valves, whose stroke-long is smaller wesentlieh than the long one of the transportation channel. By means of these slidegate valves the wood shreds in Zufiihrrichtung, lowered by the entrance connection, are moved vorwarts, whereby the wood shreds form typically a congestion, which the transverse longing CCIT Canals ausfilllt and fttr the Abase and dust striving from the silo stromaufwarts form a Propfen. In the following the invention under reference to a settled Zeiehnung besehrieben of close becomes.

Fig. 1 shows a Vordchtung, which covers oinen transportation channel 1, dor essentially rectangular transverse longing CCIT exhibits and its a long gr6Ber is as the Querschnittsh6he. At oinem end of the transportation channel, oborhalb the channel, into the channel mllndendor an entrance connection of 2 fiJr wood shreds is arranged, into which the zumfliihrenden wood shreds by means of on see well-known means of transport bef'6 rdert and into the transportation channel heruntergelasson become. At the gogeniiberliegonden Endo of the transportation channel 1 a Austfittsanschluss 4 is arranged, by that the Holzschnitzcl from cathedral transportation channel 1 lowered odor ontfomt werdon, over in oin wood shred silo bef'6 rdert too. At the entrance end of the transportation channel, in which boron-calibrate, in that the entrance connection 2 into the transportation channel 1 miindet, harm means 3 to the VorwiLrtsbewegon arranged by wood shreds, which bostehen from several slidegate valves 5, the Sehubbowogung working at the Eingangsendo of the transportation channel 1 one lainund ausfiihren. A zusarnmengerechnete Schubfliiche dor slidegate valve 5 essentially corresponds the Querschnittsflliche of the transportation channel. Vorteilhafferweise the slidegate valves asynchronously fuel element tigt, whereby at least more oiner the ski waiter in one offer-rubbed relative to the other Sehiebern asynchronon befmdet, preferably in such a way that mindostens to one dor slidegate valves see yourself rtickw trts moved, w lrend the others in Zufiihrfiehtung to move. The drive movement of the slidegate valves is oinfach and confidently by means of one from a suitable force enterprise (source of strength) propelled crank mechanism 6 attainable. As driving device also the respective slidegate valve separately odor all slidegate valve together assigned an Cylinder piston arrangement is applicable. The cylinder piston arrangement can be pneumatically odor hydraulic. A pneumatic odor hydraulic drive makes rougher degrees of freedom flit the arrangement mutual Bewegungender for ski waiter possible, dajeder slidegate valve unabh gig of the other slidegate valve adjustable is. With the Antriebseinriehtung the slidegate valves a Hubl tnge S is reached in each case, which are appropriate for the long L of the transportation channel in the rough order ½. Stroke-long S of the Sehieber lies in the same Gr Benordnung wio the H the he ski waiter. 11o QOQO QOOO OO • O • • °° °oo oo around the formation of a Holzschnitzelpropfens in the transportation channel to guarantee, can be intended in the channel the Oberfl che of the wood shred stream a beschrankender attack 7, dessert position is preferably adjustable. This attack katm as compressors of the Holzschnitzelpropfens in the Transportkaual I, wikhrend the wood shreds function yon the Schiebem 5 under the attack through vorwarts to be pushed. The transportation channel can be verjttugend trained also in Zufiihrrichtung, as or mchrere Wande is schraggestellt. The inclination degree of the Wande can be also adjustable, in order to adapt the use of the device to different Situatiohen. The transportation channel kaun by parallel to the channel running Maude 9 divided in Facher 8 its, whereby injedem the Fetcher a slidegate valve 5 works in each case. The slidegate valves exhibit in each case an Irish Republican Army substantial the Linger and the H6he of the subject 8 appropriate Ltinge and H6he. The Wtinde functions for their part as Steuenmg of the Schiebcr, how those Steuenmg also by means of at the ground of the channel more arranged, in appropriate slots of the slidegate valves 5 gefiihrten rails to be ausgefiihrt can. Invention the e Zufiihrvorrichtung fiir wood shreds is adjusting with the enterprise. During an interruption of the entrance of wood shreds from the entrance connection the slidegate valves 5 new material do not kSnnen into the transportation channel 1 sehieben, but the Holzschnitzelpropfen already produced by the Schiebem 5 remains in the Transportkaual 1 and prevents thus the migration of exhaust gases and dust in the Eintrittsansehluss 2. for the sealing attitude of the Holzschnitzelpropferm can by a Anorctuung be contributed, in which everyone is the slidegate valve 5 separately hydraulic or pneumatically propelable, whereby all slidegate valves to the Stiitzung of the Holzschrfitzelpropfens into its iiul3erste extending position adjustably harm. At the discharge end of the transportation channel 1 a force of gravity-burdening Klappensystern 10 can be intended, that as Riieksehlagventil serves soil, if in a wood shred area a clear Uberdmck present after the withdrawal connection 4 prevails, and the wood shred supply from the entrance connection 2 for any reason is interrupted. : i the density of the Holzschnitzelpropfens places itself in different load situations of the drive substantially gleieh, unabh ugig of it whether the supply is occasional more grfBer or smaller. The zugefiihrte quantity is controlled dureh the Steuertmg of the speed of the crank mechanism 6 or a zyklisehen enterprise of the pneumatisehen drive.
