[0023] The outer surface of the dust collector body 1 is hinged and connected with a box door through a door hinge, and the size of the box door is greater than the size of the inner cavity of the dust collector body 1.

[0024] Please refer toFigure 2 In order to make the entering dust-containing gas flow into the inner cavity of the dust collector body 1 uniformly, the uniform flow mechanism 5 in the embodiment includes a wind deflector 501 fixed at the bottom of the left side wall of the inner cavity of the dust collector body 1. When the dust-containing gas enters the dust collector body 1 through the air inlet pipe 2, the dust-containing gas is diverted to flow into the ash hopper communicated with the lower surface of the dust collector body 1 under the action of the wind deflector 501. At this time, the flow speed of the dust-containing gas slows down, and the coarse particle dust in the dust-containing gas directly flows into the ash hopper due to the inertial effect, thereby realizing preliminary separation. The bottom between the wind deflector 501 and the opposite side of the right side wall of the inner cavity of the dust collector body 1 is fixed with a bearing plate 502. The left and right ends of the lower surface of the bearing plate 502 are both fixed with two fixed supports 503. The opposite sides between the two fixed supports 503 are fixed with two air inducers 504. The left and right ends of the upper surface of the bearing plate 502 are both provided with two uniform flow ports 505. The two air inducers 504 are started. The air inducer 504 generates upward force. The gas rises through the uniform flow port 505 under the action of the air inducer 504, and then is ready to enter the next purification stage. The two uniform flow ports 505 help to further uniform flow, so that the dust-containing gas uniformly passes through the filter bag, improves the filtering efficiency, and can avoid direct washing of the gas to the filter bag, thereby protecting the service life of the filter bag.

[0025] The length and width of the flower plate 4 are adapted to the length and width of the inner cavity of the dust collector body 1. The wind deflector 501 is located on the upper side of the air inlet pipe 2, and the included angle between the left end and the right end of the wind deflector 501 is obtuse.

[0026] In the embodiment, the air outlet end faces of the two air inducers 504 face the opposite sides of the adjacent two filter bags.

The front and back sides of the lead screw 602 and the limiting rod 603 are both provided with lifting plates 604. The opposite sides of the front and back lifting plates 604 are both provided with brushes 605. The movement of the left end driving plate 606 drives the movement of the front and back lifting plates 604. The right end of the lifting plate 604 slides under the action of the right end driving plate 606, so that the movement of the lifting plate 604 drives the movement of the plurality of brushes 605, thereby cleaning the dust on the surface of the filter bag and improving the cleaning efficiency. The staff can open the box door to clean the dust falling on the upper surface of the bearing plate 502.

[0028] The screw rod 602 is rotatably connected between the left end of the flower plate 4 and the opposite side of the air deflector 501 through a bearing, and the number of the brush 605 is not less than two and is evenly distributed on the opposite side of the front and rear lifting plates 604.
