A butterfly valve 5 is provided at the air inlet 22, and the opening and closing of the butterfly valve 5 enables the induced draft fan to extract the powdered adsorbent from the screening machine; in the embodiment, butterfly valves are provided at the top of the first screening machine and the ends of the pipeline at the discharge port of the screening machine, and the air volume of the induced draft fan 4 is adjusted by controlling the butterfly valve.
[0029] In the embodiment, an air flow distribution plate 23 is provided at a position corresponding to the inner wall of the shell 21 and the air inlet 22, wherein the air flow distribution plate 23 is snap-connected to the inner wall of the shell 21; the air flow distribution plate 23 can guide the powdered adsorbent, so that the powdered adsorbent can move upward and be filtered by the filter bag 29 and then discharged from the clean air outlet 31.
[0030] like Figure 2 and Figure 3 As shown, one end of the exhaust pipe 34 is connected to the compressor 30, and the other end is connected to a connecting mechanism, the connecting mechanism includes an exhaust valve 32 connected to one end of the exhaust pipe 34, an exhaust shunt pipe 35 is provided at one end of the exhaust valve 32, the exhaust valve 37 is connected to the exhaust bag 33 through the exhaust shunt pipe 35, and one end of the exhaust bag 33 is connected to the filter bag opening 36 through a buckle. In the embodiment, an exhaust valve 32 is provided at one end of the exhaust pipe 34 to control the entry of compressed gas. When working, the compressed gas enters the exhaust bag 33 through the exhaust valve 32 and the exhaust shunt pipe 35. The outer sides of the exhaust valve 32, the exhaust bag 33 and the exhaust shunt pipe 35 are respectively provided with fixing frames for fixing the structure. Ventilation holes are respectively provided on the inner and outer sides of the filter bag opening 36 below the exhaust bag 38. When in use, the compressed gas will be sprayed downward along the vents, thereby achieving the effect of clearing the filter bag 29.
[0031] The top of the housing 21 is provided with a clean air outlet 31. A screen is provided in the clean air outlet 31. The clean air outlet 31 provided at the top in the embodiment is used to discharge the air after dust removal. After the dust removal device 2 filters the air, the filtered air can be further filtered and purified by the screen when passing through the clean air outlet 31, so that after being discharged, the air is transported to the exhaust pipe 3 through the pipeline under the action of the induced draft fan 4.

During the falling process of the powdered adsorbent, the switch drives the vibrator 27 to drive the discharge plate 26 to vibrate, which can facilitate the faster falling of the powdered adsorbent accumulated at the bottom of the shell 21. At the same time, the spring 25 can increase the vibration frequency of the discharge plate 26, which is helpful for the discharge of the powdered adsorbent.
