[0037] Embodiment 2

[0038] As Figures 1 to 5 shown, based on the same concept as in the above Embodiment 1, this embodiment also proposes a dust-removing assembly 8;

[0039] In this embodiment, the dust-removing assembly 8 includes a liquid separation pipeline 14, a spraying pipeline 15, a driving motor 16, a driving spur gear 17 and a positioning frame 18. The top of the sedimentation tank 1 is vertically rotatably connected with the liquid separation pipeline 14. Both sides of the bottom of the liquid separation pipeline 14 are fixedly connected with the spraying pipeline 15. The top of the sedimentation tank 1 is fixedly connected with the driving motor 16.

One end of the linkage shaft rod 19 located inside the air outlet pipeline 7 is fixedly connected with an exhaust disc 22;

[0040] In summary, starting the driving motor 16 and cooperating with the connection between the two driving spur gears 17, the liquid separation pipeline 14 drives the spraying pipeline 15 to rotate, and the liquid at the liquid supply pipeline is atomized and sprayed out through the spraying pipeline 15. Then, by using the contact between the liquid and the air flow, the dust in the air flow can be settled. And by cooperating with the connection between the driving bevel gear 20 and the accelerating bevel gear 21, during the rotation of the liquid separation pipeline 14, the driving bevel gear 20 can be used to dial the accelerating bevel gear 21, and then the exhaust disc 22 can be driven to rotate through the linkage shaft rod 19, so as to quickly discharge the dust-removed gas in the sedimentation tank 1;

[0041] Here, a plurality of water outlet holes are provided at the bottom end of the spraying pipeline 15, and an atomizing nozzle is fixedly connected inside each water outlet hole. With the arrangement of the atomizing nozzle, the liquid at the spraying pipeline 15 can be led out in a larger range, reducing the operation blind area of the spraying pipeline 15;

The airflow in the dust collection pipe will be transmitted to the filter pipe 6 through the assembly pipe 4, and the dust in the airflow will be preliminarily filtered through the filter plate 13. The airflow after the preliminary filtration will be transmitted to the inside of the sedimentation box 1 through the air intake pipe 2;

[0044] At the same time, the transmission motor 16 is started to cooperate with the connection between the two transmission spur gears 17, so that the liquid separation pipeline 14 drives the spray pipeline 15 to rotate, and the liquid at the liquid supply pipeline is atomized and sprayed out through the spray pipeline 15, and then the contact between the liquid and the airflow can be used to settle the dust in the airflow, and in cooperation with the connection between the transmission bevel gear 20 and the acceleration bevel gear 21, during the rotation of the liquid separation pipeline 14, the transmission bevel gear 20 can be used to shift the acceleration bevel gear 21, and then the exhaust plate 22 can be driven to rotate through the linkage shaft rod 19, so that the gas after dust removal in the sedimentation box 1 can be quickly discharged;

[0045] Subsequently, the central shaft 9 can be rotated, and by setting two threaded sections 10 with opposite thread rotation directions, the two displacement frames 11 drive the two connecting rings 12 to move away from each other until the connecting rings 12 move out of the filter pipe 6, thereby unlocking the filter pipe 6. Subsequently, the filter pipe 6 is removed from between the air intake pipe 2 and the assembly pipe 4, and the filter plate 13 can be cleaned or replaced to ensure the application effect of the filter plate 13.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
