The sand particles collide with each other, causing strong mechanical action to destroy the adhesive and resin layer on the surface of the sand particles, thereby improving the impurity removal effect. The water in the water tank 517 can be sent into the hollow part of the second rotating shaft 403 through the second water inlet pipe 518 and the rotary joint 516 by a water pump, and the water is sent into the water distribution pipe 512 through the first water inlet pipe 515, and finally sprayed from the spray hole 513 to the surface of the tailings sand in the storage tank 402, so as to remove impurities from the tailings sand by spraying water, and the waste water and impurities flow into the inner cavity of the feeding roller 401 through the drainage hole 514, and finally discharged from the waste discharge hole 519.

[0048] When the active roller 407 rotates, it drives the rotating wheel 610 to rotate synchronously, thereby driving the push plate 608 and the tooth plate 609 to move back and forth through the eccentric shaft 611 and the connecting rod 612, driving the fourth gear 607 and the second screw 605 to rotate back and forth, thereby driving the transverse plate 601 to swing back and forth on the surface of the support 406, and the tailings sand is moved by the material moving rod 602 to make the tailings sand evenly distributed on the surface of the magnetic conveyor belt 410, thereby improving the adsorption effect of the magnetic conveyor belt 410 on the metal debris remaining in the tailings sand, and the scraper 614 can be used to preliminarily scrape off the metal debris adsorbed on the surface of the magnetic conveyor belt 410. At the same time, the second pulley 620 is driven to rotate through the tensioning roller 409, and the first pulley 619 and the wire brush 618 are driven to rotate, so as to further clean the surface of the magnetic conveyor belt 410, and the metal debris is brushed into the collection box 613 for centralized collection, which is convenient for use.

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