Description

I

The invention is attributable to devices for breaking down the vaults of bulk material in bunkers and can be used in construction, chemical and other industries of the national economy.

The purpose of the invention is the effectiveness of the collapse of the vaults of materials.

The use of a domestic device will improve the reliability of bunker installations.

FIG. Figure 1 shows a pneumatic impulse device for breaking the bulk material vaults in the bunker in the charging position; compress the air section; in fig. 2 - the same in the position of the shot.

The device consists of a housing 1 of compressed air with an exhaust pipe 2, which can be moved along its axis by means of a sleeve 3 nuts 4 and a lock nut 5 mounted opposite the exhaust pipe on the outside of the container of the split pneumatic cylinder 6, bolted 7, the piston 8s on which nipple 9 exhaust valve

10, associated with the piston by an elastic connection, made in the form of a spring

11. For supplying compressed air to the device, there is a pipeline 12 with a solenoid valve 13., a relay 14 and 15. The working surfaces of the piston and the exhaust valve are provided with elastic pads.

The device works as follows.

In the initial position, the piston 8 and the exhaust valve 10 are not pressed against the exhaust ports 16 and 17. When applying compressed air to the cavity 18, the piston 8 blocks the opening 16, while the exhaust valve 10 has not reached the exhaust port 17. With increasing the pressure in the canals 18 compressed air through the drilling in the piston 8 and the nipple 9 enters the cavity 19 and, stretching the spring 11, presses the exhaust valve 10 to the outlet 17 (figure 1). This opens a hole 20 through which compressed air enters the housing 1, after which the device is ready for operation.

To adjust the degree of compression of the spring 11 must be unscrewed. locknut 5 and turn the release

When the relay 14 of the solenoid valve 13 has signals about the presence of a mixture in the bunker, the rotation of the conveyor belt to transport material from the bunker and the absence of material on the conveyor belt, a command is issued to switch the solenoid valve to the Exhaust position. At the same time, the pressure in the cavity 18 is released and the piston 8 releases the openings 16, stretching the spring 11 even more. As a result of the pressure on the exhaust valve of compressed air enclosed in the housing 1 and the energy of the extended spring 1t, the exhaust valve opens the outlet 17 and closes the opening 20, in which case a shot is fired with compressed air into the bunker. At the time of the shot, the compressed air also acts on the exhaust valve 10, moving it, as well as the piston 8 to the extreme left position (figure 2). This opens the hole 21 and the compressed air from the cavity 19 is released into the atmosphere. Simultaneously with the shot of compressed air, the time relay 15 is activated and after a predetermined period of time (2-3 s), the command is given to switch the solenoid valve to the Charging position.

The absence of a rod in the proposed device allows to increase the reliability of its operation, and the absence of compressed air leaks from the tank to the atmosphere reduces the shot time with compressed air to 0.1 s, which increases the efficiency of the device. Adjusting the degree of compression of the spring can be made during operation of the device. The location of the pneumatic cylinder on the outside of the tank greatly simplifies the repair of the device. and provides easy and fast access to all parts of the device. . To disassemble the air cylinder, it is enough to unscrew the bolts of the fastening bolts 7, as a result of which the repair or replacement of the worn piston, the exhaust valve, the springs or the nip pell is made within 5-1 O min.
