The circumferential surface of the volute body 1 is provided with a discharge port. The separation assembly 2 is disposed inside the volute body 1, and the air outlet pipe 22 of the separation assembly 2 passes through the through hole and is fixedly connected to the volute body 1.

[0039] The air inlet pipe section 31 is a cylindrical structure, and the connecting section 32 is a frustum structure. The inner wall of the air inlet pipe section 31 is provided with several evenly distributed blades 33. The blades 33 can guide the airflow direction, reduce the energy consumption of the fan, and at the same time increase the wind speed and enhance the separation efficiency through the tapered structure.

[0040] Preferably, the ratio of the diameter of the small round end to the large round end of the connecting section 32 is 1:2; the diameter of the duct section is the same as the diameter of the small round end; and the ratio of the height of the duct section to the height of the connecting section 32 is 2:3.

[0043] The separation section has a frustum structure; it decelerates through a gradually widening flow channel and uses gravity to settle larger particles of foreign matter, thus achieving graded sorting.

[0044] The ratio of the diameter of the large circular end to the diameter of the small circular end of the separated section is 1:2; the ratio of the height of the separated section to the height of the separated section is in the range of 1:2.5-1:3; the ratio of the height of the connecting section 32 to the height of the separated section is 10:13.

[0046] The brim 24 widens and buffers the outlet duct 22, eliminating eddies caused by the direct impact of high-speed airflow, so that the separated material is evenly distributed circumferentially and local accumulation is reduced.

[0047] Preferably, one end of the connecting rod 23 is connected to the junction of the front and rear separation sections; the other end of the connecting rod 23 is connected to the end face of the air outlet duct 22; the ratio of the length of the connecting rod 23 to the height of the rear separation section is 2:1.

[0049] Preferably, a plurality of evenly distributed connecting support plates are provided at the connection between the air outlet pipe 22 and the volute body 1.

[0050] Working principle: Under the action of airflow, the material enters the air separator and passes through the separation component 2. Lighter materials are discharged through the air outlet pipe 22 by the airflow, while heavier materials are discharged through the discharge port, thus achieving the purpose of separation.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
