[0011] A positioning cover, one end of which is fixedly connected to the upper end wall of the dust removal box, and the other end of which is fixedly connected to the guide hopper through a plurality of connecting rods;

[0012] A stopper sleeve is detachably arranged between the positioning cover and the guide hopper;

[0013] The first filter screen is in the shape of a spherical arc, and the open end is buckled on the upper port of the guide hopper;

[0014] A plurality of second filter screens, the upper ports of which are fixedly connected to the guide hopper and distributed along the guide hopper, and the plurality of second filter screens are distributed in concentric circles;

[0015] A blocking plate is detachably arranged in the discharge port;

[0016] A plurality of positioning rings are respectively fixedly connected to a port of the second filter screen away from the material guide hopper, and the positioning ring is fixedly connected to the material guide hopper through a plurality of positioning rods.

[0017] Preferably, a plurality of the second filter screens are fixedly connected to a vibration plate penetrating the second filter screen, and a vibrator is fixedly connected to the vibration plate.

[0018] Preferably, a liquid supply pipe is fixedly sleeved on the outer side wall of the ventilation pipe, and the liquid supply pipe has a plurality of nozzles penetrating the side wall of the ventilation pipe.

[0041] When the present application is in use, the fan 31 is started, and the fan 31 sucks the air in the dust removal box 10, so that the dust removal box 10 is in a negative pressure state. At this time, the rotating tube 50 and the suction pipe 51 can suck the indoor air. At this time, the sucked air can be filtered for the first time through the first filter 60, and the first filtration can block large particles of impurities. Then, the second filter 70 is filtered layer by layer, and the filtered air is discharged through the ventilation pipe 30;

[0048] See also Figure 2 , 3 The end of the positioning cover 63 away from the upper end wall of the dust removal box 10 has an external thread 64, and the stopper sleeve 65 is threadedly connected to the external thread 64, and the stopper sleeve 65 is sleeved on the outer circumferential wall of the guide hopper 61;

[0049] The stopper sleeve 65 can be connected with the external thread on the positioning cover 63 , and the stopper sleeve 65 can be moved vertically by rotating it, so as to be separated from the guide hopper 61 , so that the impurities accumulated on the guide hopper 61 fall off.

[0050] See also Figure 1 , 2 The upper end wall of the dust removal box 10 has a positioning sleeve 52, and the rotating tube 50 rotates through the positioning sleeve 52;

[0051] The positioning sleeve 52 can increase the rotation stability of the rotating tube 50 .

[0052] See also Figure 1 , 2 The upper end wall of the dust removal box 10 is fixedly connected with a servo motor 55, the output end of the servo motor 55 is fixedly connected with a gear 54, and a gear ring 53 meshing with the gear 54 is fixedly sleeved on the rotating tube 50;

[0053] The servo motor 55 can drive the gear 54 to rotate, the gear 54 can drive the gear ring 53 to rotate, and the gear ring 53 drives the rotating tube 50 to rotate.
