PURPOSE: To reduce the friction on a pipe wall by expanding a pipe diameter on this side of a bent pipe section, heating the expanded pipe to expand the fluid, then shrinking a pipe diameter so as to make the average speed of the fluid 25m/sec or more. CONSTITUTION: A straight pipe section 1 is connected to a heating pipe 5 with a diameter larger than that of the original pneumatic pipe via an expanded-diameter pipe 4, and the heating pipe 5 is heated with a heat source 6 to increase the temperature of the fluid flowing inside. After the temperature of the inside fluid is increased and its volume is expanded, the fluid is guided into a small round pipe 8 via a shrunk-diameter pipe 7 with an inclination of 15° or less so that the average speed of the fluid flowing through this round pipe 8 is made 25m/sec or more. After the average speed of the fluid flowing through the round pipe 8 is thus made 25m/sec or more, the round pipe 8 is connected to a bent pipe 9. COPYRIGHT: (C)1985,JPO&Japio ...

Mittels des fluidisierenden Rohrsegments (4) kann in kritischen Abschnitten des Förderrohrs, insbesondere im Bereich einer Schüttgutaufgabeeinrichtung (5) oder vor Umlenkstellen (39), das dort häufig in hoher Konzentration anzutreffende Schüttgut (6) fluidisiert werden, wodurch es dann reibungsarm mit verhältnismäßig geringen Gasgeschwindigkeiten weiter befördert werden kann. Die Erfindung bezieht sich ferner auf ein entsprechendes Förderverfahren. <IMAGE>

Pneumatic conveyor device and method

The invention relates to a device for the pneumatic conveyance of bulk material, with a conveying pipe ( 3 ) which defines a conveying path ( 33 ) for the bulk material ( 6 ) and in portions has a fluidizing pipe segment ( 4 ), and with a propellant gas source ( 1 ) which is connected to the conveying pipe ( 3 ) and is designed for the supply of propellant gas in the direction of the conveying path ( 33 ), the conveying pipe ( 3 ) being provided with a fluidizing pipe segment ( 4 ) at least in the region of a bulk material feed means ( 5 ) and, if appropriate, also at further critical portions of the conveying pipe, in particular upstream of deflection points ( 39 ). As a result, the bulk material ( 6 ), often to be encountered there in a high concentration, can be fluidized, with the result that it can be conveyed, with low friction, at relatively low gas velocities. The invention relates, furthermore, to a corresponding conveying method.

Automatic quantitative feeding apparatus for an aquaculture place using blower

The present invention relates to a feeding apparatus installed in a farm on the ground or a cage farm on the sea and supplying a feed to a cultured organism and, more particularly, to an automatic quantitative feeding apparatus for a farm using a blower. The feed is supplied by the use of blown air discharged from the blower. The present invention adopts a quantitative distributor that rotates a distribution rotor inside upper and lower covers and circular passage-type feed injection spaces having the same dimensions are radially formed in the distribution rotor. Then, the feed discharged from a feed storage hopper is subjected to sequential injection into the feed injection space of the distribution rotor through the upper cover. The feed stored in the feed injection space can be sequentially supplied toward a water culture tank or a cage net along a feed transport pipe through a dropping pipe connected to each of the lower cover and an air blowing pipe. The direction of the feed injection and discharge through the quantitative distributor and the direction of the rotation of the distribution rotor form an angle of 90 degrees. Accordingly, feed impairment can be minimized and quantitative supply can be performed in an accurate, effective, and economical way. In addition, the amount of feed supply can be accurately determined and a feedback control based thereon can be performed by means of the measurement of the number of revolutions of the distribution rotor. A feed spray is placed on an outlet side of the feed transport pipe and the feed spray is capable of rotating a feed spray pipe in accordance with a desired spray direction. Accordingly, feeding with respect to multiple water culture tanks or cage nets can be performed with the single feeding apparatus.

Self-cleaning product transfer device

A product transfer device is provided that includes telescoping tubular arm sections that collectively define a fluid passageway and are arranged so that a terminal arm section has the smallest diameter, while the diameters of the succeeding arm sections are increasingly larger. Piston seals in adjacent arm sections cooperate to define a chamber. A product transfer valve and isolation valve control the flow of product through the product transfer device. Pressurization of the passageway extends the arm sections and an actuator device opens the product transfer valve when the transfer arm contacts a container bottom. Pressurization of the chamber causes retraction of the arm sections so that the exterior of each arm section is wiped clean by the piston seal of the arm section into which that arm section is retracted. Retraction of the arm sections also operates a securing device that automatically shuts the product transfer valve.

Способ и реактор для поточного получения карбоната кальция в процессе производства волокнистого полотна

Изобретение может быть использовано в производстве бумаги. Карбонат кальция получают в целевой суспензии в процессе формования волокнистого полотна в машине для изготовления волокнистого полотна в реакторе, составляющем часть проточного трубопровода, транспортирующего целевую суспензию. Целевая суспензия включает суспензию целлюлозы из первичного сырья, суспензию вторичной целлюлозы, фракцию наполнителя и содержащий твердые вещества фильтрат. Реактор оснащают устройством для предотвращения осаждения РСС в реакторе. Реактор выполняют из материала, на котором РСС не способен закрепляться, или покрывают реактор таким материалом. Указанное устройство для предотвращения размещают в соединении с реактором по существу по длине, на которой реагируют диоксид углерода и известковое молоко. Изобретение позволяет получать карбонат кальция в поточном процессе без карбонатных отложений на поверхности поточного трубопровода. 2 н. и 20 з.п. ф-лы, 16 ил.
