The dust on the inner and outer surfaces is shaken off, thereby realizing the effective combination of high-pressure gas backflushing and mechanical vibration dust cleaning, and improving the dust cleaning effect on the filter cartridge 51 .

The scraper 55 on the support rod group 54 slides away from the partition plate 17 under the pressure of the high-pressure gas to scrape and clean the dust on the inner wall of the filter cartridge 51 , and the high-pressure gas is blown back and discharged to the outside of the filter cartridge 51 , the high-pressure gas slides to the initial position under the action of its own weight. When the filter cartridge 51 works for a period of time, the staff can activate the second control valve 46 to drive the branch pipe 44 to fill part of the high-pressure air into the air flow chamber 533, and the second baffle 535 moves toward the air close to the first baffle 534 under the action of the air pressure. The second baffle 535 drives the rotating bottom case 532 to rotate, and the rotating bottom case 532 drives the filter cartridge 51 to rotate through the first elastic clamping component 2, so that the peripheral surface of the filter cartridge 51 originally located at the bottom rotates to the upper part, so as to give full play to the overall filtering performance of the filter cartridge 51 and improve the service life of the filter cartridge 51 .
