[0024] Specifically, the conveying fan 2 is driven to extract air from the inside of the mine through the air inlet pipe 1 and transport it into the filter box 301, and the air is filtered by the filter component 303. The filtered clean gas is discharged from the exhaust pipe 5 through the blocking mechanism 4. When the filter component 303 needs to be cleaned, the control valve 2 605 and the two solenoid valves are closed, and the control valve 1 602 is opened to drive the air pump 604 to input high-pressure gas into the cylinder 601 through the air inlet pipe 603. When the air pressure inside the cylinder 601 reaches a certain value, the control valve 1 602 is closed and the control valve 2 605 is opened, so that the high-pressure gas inside the cylinder 601 rushes into the filter cartridge 3031, and then the gas expands and impacts the filter cartridge 3031, so that the dust attached to the outer periphery of the filter cartridge 3031 is detached and settled at the bottom of the filter box 301.

[0027] Working principle:

[0028] Drive the conveying fan 2 to extract the air inside the mine through the air inlet pipe 1 and convey it into the filter box 301. The air is filtered by the filter component 303, and the filtered clean gas is discharged from the exhaust pipe 5 through the blocking mechanism 4. When the filter component 303 needs to be cleaned, close the control valve 2 605 and the two solenoid valves, and open the control valve 1 602 to drive the air pump 604 to input high-pressure gas into the cylinder 601 through the air inlet pipe 603. When the air pressure inside the cylinder 601 reaches a certain value, close the control valve 1 602 and open the control valve 2 605, so that the high-pressure gas inside the cylinder 601 rushes into the filter cartridge 3031, and then the gas expands and impacts the filter cartridge 3031, so that the dust attached to the outer periphery of the filter cartridge 3031 is detached and settled at the bottom of the filter box 301. Finally, the drain valve 304 is opened regularly to discharge the dust. That is, it can effectively maintain the high-efficiency filtration capacity of the filter cartridge 3031. When the filter assembly 303 needs to be replaced, the electromagnet ring 407 is energized, so that the electromagnet ring 407 attracts the iron sheet, so that the sleeve 1 405 drives the sleeve 2 409 to retract into the Z-tube 401, and then the servo motor 404 is driven to make the gear 403 drive the gear ring 402 to rotate, so that the Z-tube 401 rotates, so that the Z-tube 401 is separated from the filter box 301, and the filter assembly 303 can be pulled out for replacement or maintenance. Finally, the replaced or maintained filter assembly 303 is inserted into the filter box 301, and the Z-tube 401 is reset by the servo motor 404. Finally, the electromagnet ring 407 is de-energized, and under the action of the spring 1 406 and the spring 2 408, the sleeve 1 405 and the sleeve 2 409 are reset, thereby completing the sealing. The operation is very simple and convenient.
