A containing groove matched with the positioning block 7 is arranged in the connecting block 5, and a clamping groove matched with the positioning block 7 is arranged on the side of the air inlet pipe 2. The clamping grooves are arranged in multiple groups, so that the angle of the rotating plate 3 can be adjusted, and the air inlet of the dust remover can be adjusted.

[0023] Further, referring to Figure 4 It can be known that a rotating ring 9 is arranged on the outer side of the rotating rod 4, and an annular groove matched with the rotating ring 9 is arranged on the inner wall of the air inlet pipe 2. The rotating ring 9 and the annular groove are matched with each other, so that the rotating rod 4 can be guided, and the sealing performance of the rotating rod 4 during use can be effectively ensured.

[0024] Further, referring to Figure 4 It can be known that a rectangular plate is connected to the side of the top end of the positioning block 7, and the upper side of the rectangular plate is connected to the inner wall of the containing groove through a spring 8. The rectangular plate and the spring 8 are matched with each other, so that the tightness of the positioning block 7 when clamped into the clamping groove in the air inlet pipe 2 can be effectively ensured.

[0025] Further, referring to Figure 3 and Figure 4 It can be known that a rubber ring 10 is connected to the outer wall of the rotating plate 3, the outer wall of the rubber ring 10 is tightly attached to the inner wall of the air inlet pipe 2, and the rubber ring 10 is fixedly connected to the bottom end of the rotating rod 4. The rubber ring 10 made of rubber material can effectively prevent damage caused by hard friction with the inner wall of the air inlet pipe 2.

[0026] Further, referring to Figure 3 It can be known that a vertical rod 12 is connected to the side of the rotating plate 3, and a ribbon 13 is arranged on the outer side of the vertical rod 12. An observation window 14 is arranged in the air inlet pipe 2. The vertical rod 12 and the ribbon 13 are matched with each other, so that the passing condition of the air flow can be easily determined by the staff.
