Two slots 45 are opened on one side surface of the sealing hollow block 41, and the inner wall of the slot 45 on the surface of the sealing hollow block 41 is inserted with an iron plate 43.

[0026] In this embodiment: the filter plate body 5 at the air outlet 3 and the air inlet 2 of the filter body 1 can achieve the effect of dual purification, and when the filter plate body 5 is replaced later, there is no need to shut down the equipment, and the sealing hollow block 41 is pushed, and the sealing hollow block 41 drives another filter plate body 5 to filter, and then, the sliding iron plate 43 can remove the filter plate body 5 that needs to be replaced and cleaned, thereby improving the overall ease of use.

[0027] Specifically, two magnetic rings 44 are fixedly connected to the inner wall of the slot 45 on the surface of the sealing hollow block 41. The magnetic rings 44 are magnetically connected to the iron plate 43. The magnetic rings 44 can stably restrict the iron plate 43 in the slot 45, thereby improving the overall stability effect.

[0028] Specifically, one side corresponding to the two sealing hollow blocks 41 is fixedly connected to the connecting block 48, the inner wall of the filter body 1 is rotatably connected to a screw 49, the screw 49 is threadedly connected to the inner wall of the connecting block 48, and the upper surface of the filter body 1 is fixedly connected to a motor 410, and the output end of the motor 410 is threadedly connected to one end of the screw 49.

[0029] In this embodiment, the motor 410 can drive the screw 49 to rotate, and the screw 49 can drive the two sealing hollow blocks 41 to move up and down through the connecting block 48 to realize automatic switching of the filter plate body 5.

[0030] Specifically, the inner wall of the sealing hollow block 41 is provided with two placement grooves for the filter plate body 5 to be inserted into, and both sides of the placement grooves are provided with ventilation holes.
