[0025] Furthermore, the filtering mechanism includes an external threaded ring 9, a filter screen 10, and an internal threaded ring 11. The external threaded ring 9 is located inside the exhaust pipe 7, and the external threaded ring 9 is fixedly connected to the exhaust pipe 7. A filter screen 10 is arranged above the external threaded ring 9. The filter screen 10 is an inverted cone. The bottom end of the filter screen 10 is fixedly connected to the internal threaded ring 11, and the internal threaded ring 11 is threadedly connected to the external threaded ring 9.

[0026] Furthermore, the dust collecting mechanism includes an arc-shaped dust collecting box 12 and a first clamping block 13. The arc-shaped dust collecting box 12 is semicircular, and the top of the arc-shaped dust collecting box 12 is open. There are two arc-shaped dust collecting boxes 12, and the arc-shaped dust collecting boxes 12 are symmetrically arranged at two on both sides of the exhaust pipe 7. The two arc-shaped dust collecting boxes 12 are surrounded by a circular ring. The arc-shaped dust collecting box 12 is located at the lower side of the filter screen 10 and receives the dust on the filter screen 10, which is convenient for collecting the dust of the filter screen 10 cleaned by the personnel, and is convenient for the personnel to uniformly handle. The outer wall of the exhaust pipe 7 is fixedly connected with a plurality of arc-shaped dust collecting boxes 12 at intervals along the axial direction. The dry group has first clamping blocks 13 arranged at equal intervals, and the inner wall of the arc-shaped dust collecting box 12 is provided with first clamping grooves 14, the first clamping grooves 14 correspond to the first clamping blocks 13 one by one, and the first clamping blocks 13 are clamped with the corresponding first clamping grooves 14, and a plurality of second clamping blocks 15 arranged at equal intervals are fixedly connected to the end face of the arc-shaped dust collecting box 12 located on the right side of the corresponding exhaust pipe 7, and a plurality of second clamping grooves 16 arranged at equal intervals are opened on the end face of the arc-shaped dust collecting box 12 located on the left side of the corresponding exhaust pipe 7, and the second clamping blocks 15 are clamped with the corresponding second clamping grooves 16.

[0029] Working principle: When the device is in use, the personnel first open the air intake valve 5 to allow the exhaust gas to enter the dust cover 8 from the T-shaped air intake pipe 3 through the air intake branch pipe 4. At this time, the dust in the exhaust gas will be filtered on the filter screen 10, and the exhaust gas with dust filtered out enters the exhaust pipe 7. When there is a lot of dust attached to the surface of the filter screen 10, which affects the filtering effect, the personnel closes the air intake valve 5 on the corresponding side to prevent the exhaust gas from entering the corresponding dust cover 8. At this time, the personnel moves the sleeve 20 upward so that the sleeve 20 slides axially along the air intake branch pipe 4. The sleeve 20 drives the dust cover 8 to move upward so that the plug-in block 18 moves out of the arc dust box 12. At this time, the personnel can use other tools to clean the dust attached to the surface of the filter screen 10 and sweep the dust on the surface of the filter screen 10 into the corresponding arc dust box 12. When the cleaning is completed, the personnel pulls the sleeve 20 downward so that the sleeve 20 moves downward to drive the plug-in block 18 to insert into the arc dust box. 12, thereby preventing the dust in the arc dust box 12 from leaking out. When there is a lot of dust in the arc dust box 12, the personnel moves the arc dust box 12 upward after moving the sleeve 20, the dust cover 8 and the plug-in block 18 upward, so that the first clamping block 13 and the second clamping block 15 are respectively moved out of the corresponding first clamping groove 14 and the second clamping groove 16. At this time, the personnel moves the arc dust box 12 away from the exhaust pipe 7 and removes the arc dust box 12, and the dust in the arc dust box 12 can be cleaned. When the filter screen 10 is damaged and affects the filtration, the personnel rotates the filter screen 10 after moving the sleeve 20, the dust cover 8 and the plug-in block 18 upward, so that the filter screen 10 drives the internal threaded ring 11 and the external threaded ring 9 to rotate relative to each other, thereby removing the filter screen 10. At this time, the personnel places the new filter screen 10 on the top of the external threaded ring 9, and rotates the filter screen 10 so that the internal threaded ring 11 is threadedly connected with the external threaded ring 9.
