[0028] During operation, in order to improve the dust removal effect of the dust removal device in this scheme, it is possible to remove impurities attached to the surface of the raw materials and improve the convenience of use. In this scheme, after the raw materials are introduced into the inner funnel 1, they will be located on the conical rotor 9, and the No. 1 motor 7 will be started. After the No. 1 motor 7 is started, the conical rotor 9 will be driven by the No. 1 transmission rod 8 to rotate in the inner funnel 1, and the rotation of the conical rotor 9 will drive the brush plate 10 to move on the inner surface of the inner funnel 1. At this time, the raw materials will pass through the gap between the conical rotor 9 and the inner wall of the inner funnel 1 and then enter the feed pipe 11, and the raw materials will be stirred by the rotating conical rotor 9 during the passage. At this time, the raw materials will rub and squeeze each other, and the impurities and dust on the raw materials will be removed under the action of the brush plate 10. The floating dust impurities removed under the action of the vacuum pump 20 will be sucked into the outer funnel 3, and then the dust impurities will be filtered and adsorbed by the sealing plate 22 arranged in the filter bin 21, which can achieve the effect of improving the dust removal effect and effectively increase the convenience of use of the dust removal device.

[0029] Working principle: by starting the vacuum pump 20 and the No. 2 motor 18, the vacuum pump 20 will simultaneously perform vacuum operation on the outer funnel 3 and the sleeve 14, and the No. 2 motor 18 will drive the auger 17 to rotate in the feed pipe 11 through the No. 2 transmission rod 16 after starting, and then pour the raw materials to be ground from the feeding port 5 into the inner funnel 1, and the dust generated during pouring is sucked into the outer funnel 3 through the No. 1 air vent 2, and then the raw materials in the inner funnel 1 will leak into the feed pipe 11 from the bottom of the inner funnel 1. Since the feed pipe 11 is inclined, the raw materials will fall to the lower end of the feed pipe 11 after entering the feed pipe 11. The auger 17 is arranged in the feed pipe 11. Under the rotation and transportation of the auger 17, the raw materials in the feed pipe 11 will slowly move to the lower end, and the raw materials will be turned over as the auger 17 stirs during the movement. At this time, the dust and impurities in the raw materials will be sucked into the sleeve 14 through the No. 2 air vent 12, and then sucked into the No. 2 exhaust pipe 15 through the sleeve 14. The turned raw materials will finally be discharged from the discharge port 19, thereby achieving the effect of multiple dust removal. Compared with traditional dust removal devices, the dust removal effect is better, the raw materials can be turned over effectively and the raw materials can be prevented from being left in the device, thereby improving the practicability of the device.

[0030] After the raw materials are introduced into the inner funnel 1, they will be located on the conical rotor 9, and the No. 1 motor 7 will be started. After the No. 1 motor 7 is started, the conical rotor 9 will be driven to rotate in the inner funnel 1 through the No. 1 transmission rod 8, and when the conical rotor 9 rotates, it will drive the brush plate 10 to move on the inner surface of the inner funnel 1. At this time, the raw materials will pass through the gap between the conical rotor 9 and the inner wall of the inner funnel 1 and then enter the feed pipe 11, and the raw materials will be stirred by the rotating conical rotor 9 during the passage. At this time, the raw materials will rub and squeeze each other, and the impurities and dust on the raw materials will be removed under the action of the brush plate 10. The floating dust impurities removed under the action of the vacuum pump 20 will be sucked into the outer funnel 3, and then the dust impurities will be filtered and adsorbed by the sealing plate 22 arranged in the filter bin 21, which can achieve the effect of improving the dust removal effect and effectively increase the convenience of using the dust removal device.
