Description

The invention relates to a device for the breaking of vaults of bulk materials in bunkers and can be used in the metallurgical, chemical, construction and other sectors of the national economy.

The purpose of the invention is to simplify the control of the pneumatic breakage device by providing automatic follow-up of air pulses and simplifying the design.

The connection of the cavity of the pneumatic impulse device with the cavity of the control valve by means of piping and securing the stem of the control valve on its diaphragm allows for the automatic following of the pneumatic pulses and eliminating the external system for providing a shot.

The drawing shows a pneumatic blower for breaking down material arches in bunkers.

The device comprises a housing 1 with a barrel 2, a diaphragm 3, a chamber Ac with a partition 5 and openings 6, grooves 7 for air discharge into the atmosphere, a diaphragm 8, a disk 9 with a valve 10 for supplying compressed air and openings 11, a membrane 12, a stem 13 with a plug 14, a cover 15, a bypass pipe 16 with check valves 17 for connecting the cavity of the housing 1 with the cavity of the control valve housing 18, a bypass pipe 19 with the throttle 20 and the check valve 21 for connecting the diaphragm cavity of the valve 22 with the housing cavity

A pneumatic impulse device for breaking the vaults of materials in a bunker operates as follows.

Compressed air is supplied to the channel 10 of the disk 9, fills the cavity 18 of the control valve body, presses the plug 1A, which closes the opening 23 and enters the cavity through the holes 11 between the diaphragm 8 and the disk 9. At the same time, the diaphragm 8 blocks the holes 6, and through

pipe 16 and the check valve 17 compressed air enters the cavity between the diaphragm 3 and the partition 5, presses the diaphragm 3 to the outlet 24 of the barrel 2 and fills the working cavity of the device. Through the bypass pipe 19 and the choke 20, the supra-diaphragm cavity of the control valve is filled. With increasing air pressure in it up to

The magnitude of the membrane 12 with the brush 13 and the plug 14 is moved to a position that blocks the channel 10 for the supply of compressed air. The air from the cavity between the disk 11 and the diaphragm 8 is released through the hole 25 into the atmosphere. The pressure in the cavity will decrease, the diaphragm 8 will open the opening 6 and the air from the cavity of the control chamber will be released into the atmosphere through the slots 7,

The diaphragm 3 opens the inlet 24 of the barrel 2 - a shot occurs. Compressed air from the supramembrane cavity of the control valve through the pipe 19 and the check valve 21 enters the cavity of the housing 1, the diaphragm 12 with the stem 13 and the plug 14 moves and closes the opening 23 - the device reverts, etc.

When the control valve is triggered, the air from the valve cavities, the disk 9 and the control chamber is discharged to the atmosphere at the shortest distance, which ensures an instantaneous departure of the diaphragm 3 that covers the hole of the barrel 24, and the check valves 17 prevent air leakage when fired from the housing cavity 2 into the cavity of the chamber and the cavity of the valve body 18, eliminating partial equalization of pressure in these cavities, which prevents instantaneous withdrawal of the diaphragms 3, which provides a powerful pressure pulse, and the presence of a bypass nozzle and 19 with a throttle 20 and a check valve 21 make it possible. It is necessary to carry out automatic follow-up of air blows when supplying compressed air to the device and adjust the pulse frequency.

In order to simplify the construction, the control valve disc 9 can be combined with a pneumatic pulse device control valve.
