The second spring 608 is fixedly connected to the second spring 608 and the inner wall of the fixed frame 601 on both sides, respectively.

[0031] Specific implementation method: The large dust molecules in the gas will first fall to the bottom of the air box chamber tube 1 under the action of gravity through the equalizing plate 606, and then the gas will increase the collision effect of the dust particle molecules inside when passing through the first through hole 607, so as to filter it again, and help reduce the adhesion of dust on the surface of the subsequent filter bag 4, thereby ensuring the filtering effect and performance of the equipment during use. The sliding plate 503 will continuously squeeze the second air bag 603 during the movement, and transport the internal gas of the second air bag 603 to the first air bag 602 through the air duct, so that the first air bag 602 will expand and drive the slide plate 604, the connecting block 605, the equalizing plate 606 and the first through hole 607 to move up and down continuously, so as to reduce the adhesion of dust on the inner surface of the first through hole 607, thereby preventing it from being blocked after long-term use, and thereby preventing it from affecting the performance of the equipment, thereby ensuring the overall working performance of the equipment.

[0032] Working principle: When in use, the dusty gas from the outside is transported to the corresponding air box chamber cylinder 1 through the switching air inlet 7. At this time, the gas will first pass through the equalizing plate 606 and the first through hole 607 to enter the vicinity of the filter bag 4. The equalizing plate 606 will first cause the large dust molecules in the gas to fall to the bottom of the air box chamber cylinder 1 under the action of its gravity. Then, when the gas passes through the first through hole 607, the collision effect of the dust particle molecules inside will be increased. Finally, the filter bag 4 will filter the gas again. The filtered gas is discharged through the air outlet pipe 8 and the induced draft fan 9. The cylinder 502 is started according to actual needs, so that the cylinder 502 drives the sliding plate 503 and the rack 504 to move back and forth in a straight line. The linkage effect between the rack 504 and the gear 505 is used to transmit power to the gear 505, so that the gear 505 drives the screw 506 to rotate, and then the screw 50 6 and the threaded sleeve 507 have a linkage effect, which transmits power to the threaded sleeve 507, and under the restriction of the circular through hole and the round rod, the threaded sleeve 507 can only drive the fixed rod 508 and the protrusion 510 to move downward, and the protrusion 510 will squeeze the roller 511 during the downward movement, so that the roller 511 drives the fixed plate 512, the guide rod 513 and the arc block 514 to move in the direction of the filter bag 4 and vibrate it, and the sliding plate 503 will continuously squeeze the second air bag 603 during the movement, and the internal gas of the second air bag 603 is transported to the first air bag 602 through the air duct, so that the first air bag 602 expands and drives the slide plate 604, the connecting block 605, the averaging plate 606 and the first through hole 607 to move up and down continuously, so as to reduce the adhesion of dust on the inner surface of the first through hole 607, which is convenient to use.
