Abstract

This invention relates to a pneumatic transport. The purpose of the invention is to increase efficiency by reducing the losses of the overloaded bulk material and the cost of its reloading. The device contains a compressor station, a compressed air supply pipeline, a bulk material receiving bunker, a transport pipeline, the initial section of which is made flexible and provided at the entrance with a receiving chamber 4 with a sealing valve 10, a pneumatic vibrator 13 on a conical bottom and an air distributor 7 that direct the compressed air alternately pneumatic vibrator 13 or into the receiving chamber 4. The conical bottom of the chamber is provided with a divider 14 located in relation to the bottom with a gap into which the exhausted compressed air is supplied from pneumovibrator. The receiving chamber is also provided with an aspiration valve 20 with a pneumatic actuator from a stream of compressed air supplied to the chamber for transporting bulk material. 3 hp f-ly, 2 ill.

Description

compressed air, bulk material receiving hopper, transport pipeline, the initial part of which is made flexible and provided with an inlet chamber with a sealing valve 10, a pneumo-vibrator 13 on a conical bottom and an air distributor 7 that direct the compressed air alternately into an air-vibrator 13 or into the receiving chamber k . Conical days

The chambers are provided with a divider 1A located in relation to the bottom with a gap into which the exhausted compressed air is supplied from the pneumatic vibrator. The receiving chamber is also provided with an aspiration valve 20 with a pneumatic actuator from a stream of compressed air supplied to the chamber for transporting bulk material. 3 hp ff, 2 ill.

The invention relates to the pneumatic transportation of bulk materials and can be used in all sectors of industry and agriculture to transfer bulk materials mainly from bunker-type wagons to storage facilities.

The aim of the invention is to increase efficiency by reducing the loss of the overloaded bulk material and the cost of reloading it.

FIG. 1 is a schematic diagram of the proposed device; in fig. 2 - receiving chamber, section.

A device for pneumatically transporting bulk materials contains a receiving bin 1, a transport pipeline 2 with a flexible section 3 at the end of which a receiving chamber A is installed, and a compressor station 5 connected to the receiving chamber k by a pipeline 6 through an air distributor 7. The receiving chamber is provided with an opening 8 for loading of the material being transported, the discharge pipe 9 connected to the flexible section 3 of the transport pipe and the valve 10 mounted on the pipe 11 which is mounted on a rigid A nozzle 12 fastened in the chamber k with the possibility of vertical movement,. The conical bottom of the chamber h is equipped with a pneumatic vibrator 13 and a divider 1 installed with a clearance relative to the conical bottom. The air distributor 7 is connected with one outlet nozzle 15 to nozzle 12, and another outlet nozzle 16 with a pneumatic vibrator 13. Nozzle 12 is provided with openings 17 in the lower end of the nozzle 11 with the valve 10 closed and connected to a pressure sensor 18 installed remotely

Together with the command device 19, electrically connected to the pressure sensor and the electromagnet of the distributor 7. The receiving chamber is also equipped with an aspiration valve 20 diaphragm type a with a diaphragm actuator compressed air supplied to the chamber through the nozzle 15, for which the latter is connected to the valve by the nozzle 21 .

When unloading bulk material from the bunker-type wagon 22, the device operates as follows.

The loading hatch 23 is opened and the flexible section 3 of the pipeline .2 is lowered through it onto the surface of the bulk material. The command apparatus 19 switches on and installs the air distributor 7 in the position where the compressed air is supplied to the pneumatic vibrator. Then turn on the compressed air supply to the system. Under the influence of weight, vibration and aeration of the bulk material with exhaust air discharged from under the dissector I t, the receiving chamber k is immersed in the layer of bulk material. In this case, valves 10 and 20 are in the open position. After complete immersion, the bulk material, together with the aerating air, passes through the opening 8 into the chamber A and fills it. em it, while the dusty aerating air through the valve 20 goes into the hopper 1.

By switching the diffuser 7, the compressed air® supply to the pneumatic vibrator 13 is stopped. Compressed air through the pipe 15 is supplied to the pipe 12. Under the action of its valves. 10 and 20 are closed. Through the holes 17, and the gap between the nozzles 11 and 12, the compressed air enters into the chamber 4 and carries the bulk material along

the pipe 9 and the pipeline 2 into the receiving bin 1. After the chamber and the pipeline from the bulk material have been emptied, the pressure drops and the pressure sensor 18 through the command device 19 switches the air distributor 7 to the air supply, and to the pneumo-vibrator. Valves 10 and 20 open, and chamber f is loaded with a new portion of bulk material. During each cycle of operation during operation of the pneumatic vibrator 13, the bulk material around the chamber is aerated with exhaust air. Vibration of the chamber also helps to improve the flow of bulk material into the chamber.

In this way, the bulk material is unloaded from the bunker-type car through loading hatches. Likewise, unloading of bulk material from any bunker can be organized.
