[0004] Although the above patent can avoid the situation where the rare earths after filtration contain waste residues, the above patent can only remove the impurities screened out by each layer of filter screen in a unified manner after the overall rare earth waste screening is completed. Not only is the operation cumbersome, but it is also very easy to cause the impurities to be retained in each layer of filter screen, resulting in the unfavorable situation of reduced screening rate of rare earth waste, which in turn causes the rare earth waste raw materials to be blocked by impurities and have to be removed in a unified manner, resulting in waste of raw materials.
