The second filter plate 45 is slidably installed in the feed housing 2, and the two ends of the second filter plate 45 are fixedly connected to the movable ends of the two second telescopic rods 46 respectively. The two first magnets 47 are symmetrically and fixedly installed at the two ends of the second filter plate 45. The two second magnets 48 are symmetrically and fixedly installed on the feed housing 2, and the first magnets 47 can be mutually adsorbed with the second magnets 48.

[0049] The driving assembly 7 works and drives the reciprocating screw 42 to rotate. The rotation of the reciprocating screw 42 drives the reciprocating plate 43 to reciprocate in the feed shell 2, and the red mud on the first filter plate 41 is evenly spread on the first filter plate 41, so that the red mud can fall evenly between the first roller 61 and the second roller 62, thereby improving the grinding efficiency.

[0050] When the two reciprocating plates 43 move toward each other, the movement of the reciprocating plates 43 drives the movable end of the first telescopic rod 44 to extend, one movable end of the second telescopic rod 46 extends, and the other movable end of the second telescopic rod 46 shortens, and the second filter plate 45 moves toward one end of the feed shell 2, and a group of first magnets 47 and second magnets 48 are adsorbed. At this time, the filter holes on the first filter plate 41 are connected with the filter holes on the second filter plate 45, and the red mud can enter the device shell 1 from the feed shell 2 to realize the feeding operation.

[0051] When the two reciprocating plates 43 move away from each other, the movement of the reciprocating plates 43 drives the movable end of the first telescopic rod 44 to shorten. When the force applied by the first telescopic rod 44 to the second telescopic rod 46 is greater than the magnetic force between the first magnet 47 and the second magnet 48, one movable end of the second telescopic rod 46 shortens and the other movable end of the second telescopic rod 46 lengthens. The second filter plate 45 moves toward the other end of the feed shell 2, and another group of first magnets 47 and second magnets 48 are attracted. At this time, the filter holes on the first filter plate 41 are blocked by the second filter plate 45, and red mud cannot enter the device shell 1 from the feed shell 2, so as to avoid excessive red mud entering the device shell 1 and affecting the normal operation of the grinding assembly 6.

[0052] The implementation principle of the integrated red mud grinding and screening device in the embodiment of the present application is as follows: the red mud to be ground and screened is poured from the feed shell 2, enters the grinding component 6 through the feed component 4, the grinding component 6 grinds the red mud, and the ground red mud enters the screening component 5, the screening component 5 screens the red mud, and the red mud with a diameter that meets the process requirements is screened and collected in the collecting tank 31 through the discharge shell 3, thereby completing the processing of the red mud, improving the red mud screening efficiency, and reducing labor costs.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
