One end of the air cannon body is formed with a flange head, and the inner cavity of the flange head is communicated with the inner cavity of the air cannon body. The sleeve and the flange head are connected through a flange plate. The flange head is provided with an inner sealing groove coaxially arranged with the inner cavity on the end face, and the flange plate is provided with an outer sealing groove coaxially arranged with the through hole, including an air cannon body and a sleeve. One end of the air cannon body is formed with a flange head, and the inner cavity of the flange head is communicated with the inner cavity of the air cannon body. The sleeve and the flange head are connected through a flange plate.

[0024] As Figure 1 shown, the present utility model provides a dust collector bag clogging clearing device, which includes a gas storage tank 1, a thrust transmission device 2, an exhaust pipe 3 and a submerged pulse valve 4. One end of the gas storage tank 1 is provided with an external pipeline 5, the other end of the gas storage tank 1 is provided with a round hole 6, and one end of the gas storage tank 1 far from the round hole 6 is provided with an air release valve 9. One end of the exhaust pipe 3 passes through the round hole 6 and extends into the interior of the gas storage tank 1. The exhaust pipe 3 and the round hole 6 are detachably sealed and connected through a dust-proof sealing ring. The other end of the exhaust pipe 3 is provided with a detachable nozzle 7;

[0025] The thrust transmission device 2 includes a thrust transmission pipeline 202, a sealing baffle 201, a pneumatic spiral tube 204, and a moving piston 205. The sealing baffle 201 is flange-connected to the thrust transmission pipeline 202. The other end of the thrust transmission pipeline 202 passes through the external pipeline 5 and extends into the interior of the gas storage tank 1.

[0026] Embodiment

The compressed air flow enters the pneumatic spiral tube 204 through the gas guide pipe 8. The pneumatic spiral tube 204 guides the compressed air flow into the thrust transmission pipeline 202. The air flow in the thrust transmission pipeline 202 pushes the moving piston 205 to move rightward. Close the air release valve 9. At this time, the clogging removal device is in a state of waiting for blasting.

[0028] The microcontroller controls the submerged pulse valve 4 to automatically reverse, and the remaining air flow in the thrust transmission pipeline 202 is discharged. At this time, the pressure in the thrust transmission pipeline 202 and the gas storage tank 1 is out of balance, and the moving piston 205 quickly moves back under the internal pressure of the gas storage tank 1. At the same time, the compressed air flow in the gas storage tank 1 enters the exhaust pipe 3 and is quickly ejected through the detachable nozzle 7.
