[0002] In the process of comprehensive utilization of valuable metals recovered from ferroalloy waste slag, it is usually necessary to use a sand washer to clean the water-quenched slag. The most common sand washer on the market at present is a wheel-type sand washer. The wheel-type sand washer has the characteristics of simple structure, less loss of fine sand and stone powder, convenient maintenance of the sand and stone washer, large processing capacity, small power consumption, high washing degree, etc., and is widely used. However, when the existing wheel-type sand washer is working, sand, foreign objects, etc. are easily stuck in the mesh holes of the filter screen ring, causing the mesh holes to be blocked, which is not conducive to the dehydration of sand and stone. Moreover, some fine sand, silt and impurities, etc. are easy to precipitate and accumulate in the wheel bucket after passing through the filter screen, and cannot be discharged in time, affecting the rotation of the wheel bucket and the washing efficiency.

In this embodiment, the central shaft 404 is driven to rotate by a set of driving members 3, and the rotating scraper assembly 5 rotates in the same direction as the central shaft 404. Since the planetary carrier 402 is fixed, the sun gear 405 drives the large gear ring 401 to rotate in the opposite direction through the planetary gears 403, so that the sand washing wheel bucket 2 rotates clockwise to drive the water quenched slag and sand to roll and grind against each other, removing impurities such as soil and dust covering the surface of the water quenched slag, and destroying the water vapor layer covering the slag particles to facilitate dehydration. At the same time, when the rotating scraper assembly 5 rotates counterclockwise in the sand washing wheel bucket 2, the foreign objects blocking the filter screen ring 202 of the sand washing wheel bucket 2 are scraped off, preventing the filter screen ring 202 from being blocked, and stirring up the fine sand, silt, etc. deposited inside the sand washing wheel bucket 2, avoiding the accumulation and precipitation of fine sand inside the sand washing wheel bucket 2 and affecting the rotation, effectively improving the washing efficiency and saving energy.
