(5) DEVICE FOR BULK MATERIAL PUMP

I

The invention relates to pneumatic conveying of bulk materials, in particular, devices for suctioning bulk material.

BACKGROUND OF THE INVENTION A device for suction of bulk material is known, comprising a pipeline in communication with a vacuum source, a carriage movably mounted thereon with a branch pipe communicating with a transport pipeline by means of a gasket 1 sealed in the last slot.

The disadvantages of the known devices are their limited use due to the low reliability of the sealing Elastic hoses that are under excessive air pressure and do not allow to suck out material with a high temperature due to their burning and rupture by excessive air pressure.

The purpose of the invention is to increase the reliability of the device.

The goal is achieved by the fact that the seal is made of steel tape, one end of which is attached to the pipeline, the device is equipped with a belt tensioning mechanism connected to its other end, while the guide blocks under the steel pipe are fixed to the outer surface of the nozzle, and inside the nozzle is installed hollow box through which passed

10 steel ribbon.

FIG. 1 shows the proposed device (time), general view; on .fig. 2 shows section A-A in FIG. one; in fig. 3 — node 1 in FIG. one.

The device comprises a transport pipeline 1, through which the carriage 2 moves with a branch pipe 3 fixed on it, one end of which is placed in a longitudinal slot formed in the transport pipeline 1.

The slot of the transport pipeline 1 is overlapped with steel tape 39 of that 5, which is fixed at one end to the transport pipeline 1, and a load 6 is suspended to the second end of the belt 5, which carries its constant tension. For the passage of the tape 5 inside the pipe 3 without disrupting. nor its tightness in it is made through the duct 7, protected from above by the visor 8 from wear by the flow of material. To seal the joint of the carriage 2 with the tape 5, on the plane of the carriage 2 adjacent to the slit 4 of the transport pipeline 1, the bevels symmetrically located on both sides of the nozzle 3 are made: the bevels 3 have guide blocks 10 on their side surface supporting the tape 5 suction bulk material works as follows. When creating a vacuum in the pipeline 1, the tape 5 is pressed against the pipeline 1 due to the pressure difference between the atmospheric pressure and the pressure inside the transport pipeline 1 and thereby seals the gap 4. When the carriage 2 moves with the pipe 3 along the pipe 1, the belt 5 passes through the pipe 3, without disturbing him re

meticulousness. The flow of matter, sucked through the pipe 3, enters the pipeline 1, and then is transported to the place of deposition. Deformation tape 5; associated with its heating, as well as with the heating of the pipeline 1, compensates for the constant tension of the belt 5 due to the load 6.

through which the steel ribbon is passed.
