The rare earth polishing powder is widely applied to polishing of optical glass devices, fine grinding of precise instruments and the like due to the ideal polishing effect. When the rare earth elements are separated from the waste polishing powder by precipitation, the separation effect is affected by the main impurities Si and A1 in the waste polishing powder. Therefore, it is necessary to remove the impurities of Si and a1 from the waste polishing powder. Aiming at the removal of silicon-aluminum impurities, the polishing powder and the reaction liquid are added into a processing barrel in the traditional technology to react by itself, so that the polishing powder cannot be screened, and the polishing powder is not uniformly distributed, so that the polishing powder and the reaction liquid do not react sufficiently, and the working efficiency is reduced.

The equipment for removing the silicon-aluminum impurities from the rare earth waste polishing powder also comprises an inclined spoiler 9; the two sides of the bottom water tank top plate 11 are fixedly connected with inclined spoilers 9.
When silicon-aluminum impurities in the rare earth waste polishing powder need to be removed, the second motor 15 is started to work at first, and then the mounting plate 10 is driven to rotate, and further the mounting box body 21 and the vibration filtering device 14 and the filter screen plate 23 on the mounting box body are driven to rotate. Then, a proper amount of polishing powder is added into the installation box body 21 from the feeding pipe 17, and then the polishing powder is uniformly distributed on the filter screen plate 23. Meanwhile, the vibration filtering device 14 is started to work, and then the up-and-down motion of the small amplitude of the filter screen plate 23 is driven, so that the polishing powder on the upper filter screen plate 23 can drop down more quickly, and the mesh of the filter screen plate 23 from top to bottom is smaller and smaller, so that the polishing powder with larger particles can be retained on the filter screen plate 23 on the top layer, and then the polishing powder with smaller particles can drop on the filter screen plate 23 on the lower layer until the polishing powder drops to the bottom in the installation box body 21, and further the screening effect is achieved.
When the polishing powder is added, a proper amount of reaction liquid is added into the installation box body 21 through the liquid inlet pipe 19, and the reaction liquid can be in full contact with the polishing powder, so that the reaction can be performed fully, and the working efficiency is improved. Meanwhile, the vibration filtering device 14 drives the filtering screen sieve plate 23 to move up and down in a small range, so that the reaction liquid can be fully contacted with the polishing powder, and further, the reaction can be fully performed.
When the reaction of the polishing powder and the reaction liquid is finished, the lifting mechanism 2 is started, so that the cover body 6 moves upwards to a proper position. Meanwhile, the second motor 15 is started to rotate in an accelerating mode, so that the mixed liquid on the filter screen plate 23 can be thrown onto the inclined wall surface 20 and then falls to the bottom in the outer shell 1. Meanwhile, the mixed liquid at the bottom of the installation box 21 flows into the annular downstream plate 13 and then enters the bottom of the outer shell 1 through the feed inlet 8. When there is a remaining mixed liquid on the inclined wall surface 20, cold water can be fed through the water inlet pipe 3, so that the mixed liquid remaining on the inclined wall surface 20 can be flushed into the bottom of the outer case 1. The temperature of the mixed solution after the leaching reaction needs to be reduced to room temperature to obtain the leachate after the reaction, so that the cold water can reduce the temperature of the mixed solution after the reaction.
When the temperature of the mixed solution after the leaching reaction needs to be reduced to room temperature, the closed air inlet mechanism 7 is started at first, and then the feed inlet 8 is closed. Then, cold air is introduced into the input end of the closed air inlet mechanism 7, so that the cold air can cool the mixed liquid at the bottom in the outer shell 1. At this time, the cold air is discharged through the annular heat transfer pipe 18, and when the cold air is discharged through the annular heat transfer pipe 18, the cold air can cool the annular heat transfer pipe 18, and further, the mixed liquid can be cooled, so that the cold air can be utilized more sufficiently.
Meanwhile, the rotation of the second motor 15 also drives the linkage stirring mechanism 16 to work, so that the output end of the linkage stirring mechanism 16 can stir the mixed liquid, the mixed liquid can be cooled, and the cooling effect is achieved. Meanwhile, when the output end of the linkage stirring mechanism 16 stirs the mixed liquid, the mixed liquid will wave, and at the moment, the mixed liquid can be contacted with cold air more sufficiently, so that the cooling speed of the mixed liquid can be accelerated.
