FIG. one

The invention relates to industrial pneumatic transport, in particular, to the preparation of a mixture of air and devices for introducing it into the transport pipeline, and can be used in all sectors (industry and agriculture).

The gap of the invention is an increase reliably (|: ty in operation.

 Performing an air distribution elf in the form of a washer, covering the branch pipe, internally and externally forming, which is beveled, allows air to be delivered to the center of the housing and increase the discharge capacity.

FIG. 1 depicts a pneumatic feeder, an obtion of view; in fig. 2 - air chamber.

The device includes a hermetic ko-pus 1 with a loading valve 2. In the lower part of the tank, a cylindrical air chamber 3 is connected, through which the nozzle 4 passes along the axis for the removal of material with a beveled upper part of the inside surface. Camera 3 top closed

 air distribution unit

TOid, made in the form of a washer 5, vertically spring-loaded with bolts 6. The fitting is equipped with a nozzle 7 for supplying 1 and compressed air into the air chamber pe | with a relief valve 8. The inner side is 5-sided, and the washers 5 and the upper part of the outer-heii side surface of the nozzle 4 are ujeJHbi, and the outer side is formed, and the washers in the upper part are annular protrusion 9 with the lower He | i one .

I The method is carried out as follows.

Case 1 is periodically charged with trans- | dustable pulverized material. After sealing the valve 2, compressed air is supplied to the pipe 7. At the same time, the pulverized material that gets into the branch pipe for removal is picked up by the air, which, having overcome the resistance of the spring, lifts the washer 5 and, breaking through. clump into the resulting gaps; mixes with pulverized materials and at the expense of the created excessive pressure enters the outlet 4 for removal and further into the transport pipeline. A domed air flow over the nozzle 4 prevents the aerated material from entering the transport line. The air flow further reduces the concentration to an optimum value and creates an air cushion in the wall area. The airflow that flushes the containers from the inside completely cleans it in the final phase of the work cycle.
