专利摘要:
A method and apparatus for conveying particulate material of the type wherein it is desired that the material be simultaneously pre-compacted from a generally loose state to a more or less solid "plug" state. A screw conveyor is arranged to deliver loose particulate material to an intermediate chamber at the end of the screw conveyor means wherein the material is pre-compacted by the action of the screw conveyor. Following the intermediate chamber, a piston reciprocating coaxially with the screw conveyor further urges the material in a direction coaxial with the centerline of the screw conveyor to further advance the material through a straight coaxial conduit within which the material becomes compacted to an increased degree of compactness, solely by the action of the reciprocating piston. The reciprocating piston has preferably an annular face, whose outside diagram is generally the same as that of the Industrial Design of the conduit. The second, high degree of compactness is thus achieved solely by the action of the piston. Accordingly, the mounting of the screw conveyor is not subjected to extreme forces. The device is capable of compacting, for instance, fibrous material of a relatively low fibre shear strength to an extremely high compactness without exceeding the fibre shear limit in the area of the screw conveyor. Frictional drag in the conduit following the apparatus may be increased by vanes protruding inside of the conveyor. The depth of the friction increasing vanes may be selectively adjustable.

The invention relates to hoisting machinery, namely, to screw conveyors for transporting loose, loose, fibrous material into the pipeline.
A known method of transporting material, comprising feeding the material with a screw conveyor into the chamber under pressure, where then the material is sealed with a piston 11].
The disadvantage of this method is that it cannot be used for transporting loose, fibrous material.
The closest technical solution to the proposed method of transporting material is a method of transporting material, which consists in the fact that the material from the output of the feed hopper to the processing zone of the material is transported by an auger in the axial direction and the material is compacted with it in the first zone [2).
A disadvantage of this method is that this method but nevozmozh2 compacted material to a degree of compaction needed for further processing of the material, and a low efficiency, 6 NOSTA transportation.
The closest technical solution to the proposed device is a device for transporting material, including a cylindrical housing with a feed hopper and an unloading hole, a screw placed in the housing, a pipeline fixed coaxially to the housing ”and drive Г2].
.
The purpose of the invention is to increase the efficiency of transportation.
This goal is achieved by the fact that the material is discharged into the second .-. 20th zone, located coaxially with the first and immediately behind it, and behind. > m it is additionally compacted by means of a coaxial pulsating force in the second zone and further 25 ’further translational movement is carried out

A device for transporting material in the form of particles works as follows.
When the drive 11 is turned on, the auger 4 starts to rotate and feed material from the hopper 1 in the direction of the breach chamber 7, which at that time is the first sealing zone, since it is compacted with the auger while transporting the material. When the material completely fills the entire cross section at the inlet of the pipeline, then it translationally moves using the reciprocating motion of the hollow piston 6, the end of which pushes the accumulated mass in the direction of the second zone 12, which leads to further compaction of the material forming the briquette, the density of which increases significantly by compared with the density in the chamber 7, in which the material leaves the area of the screw.
Thus, the translational movement of the compacted mass through the pipeline 5 is carried out only under the influence of the reciprocating movement of the hollow piston 6, and the material is continuously fed to the pipeline by the screw 4. The action of the piston 6 of the reciprocating movement is shown schematically in Fig. 5 "where zone A shows fibrous material in the state of pre-compaction, translationally moving under the action of the screw 4 into the pipe 5 · Reciprocating moving piston 6 is additionally compacted the material to a high degree of compactness, which is achieved in zone B of the pipeline 5 · Due to the annular shape of the front of the piston 6 and the translational movement of the material through the pipe 5, stresses within the compacted mass are considered to have an arcuate shape, which contributes to the longitudinal strength of the formed compact briquette in zone B.
To achieve even greater compaction in the area of the pipeline 5, the material is subjected to a force that frictionally slows down the surface of the specified mass of material. This force is regulated by installing the plates 9 by the control mechanism 10 at a certain depth of penetration into the material. The deeper the penetration of the plates 9, the greater the friction force of braking, respectively, of the plate. They can control the degree of compaction of the material.

The hollow shaft 19 is arranged for rotation on the core sleeve 24, inside of which a piston 25 with a rod 45 of 26 is placed, the piston rod 26 being slidably mounted relative to the gasket 27. A recess is made in the front surface of the piston 25 to provide an annular front part 28,
A device for transporting material works as follows. 55
The drive sprocket 22 from its own drive (not shown) drives the screw 16. At the same time, thanks to the drive 18, begin.
929004 6 The piston moves reciprocally. The material comes from the feed hopper 14 to the surface of the screw 16, which begins to move 5 and the cylindrical body 13 and further to the intermediate chamber 23, where it is additionally sealed with a piston 25. At the entrance to the pipe 17, the material is already preliminarily densified and then moves forward only under the action of the return - progressively moving piston 25.
In the second version of the transportation device, as in the first), even greater compaction can be achieved by using only the friction of the material on the inner walls of the pipeline, which provides the adequate braking force required for compaction.
