[0002] Rare earth polishing powder refers to a powder of mixed light rare earth oxides with cerium oxide as the main component for improving the surface finish of products or parts. It is usually made from bastnasite concentrate or soluble rare earth salts through chemical treatment, calcination, pulverization, screening and other processes. During the production process, it is necessary to dehydrate and pressure filter the mixed solution containing rare earth polishing powder.

[0003] Currently, when using a pressure filtration device, there is a lack of an auxiliary vacuum water collection mechanism. Usually, when using a pressure filtration device to dehydrate rare earth polishing powder, dehydration is only achieved by extrusion filtration. Since the repeated extrusion takes a long time and the separated water needs to be collected by its own flow, the actual pressure filtration time is relatively long, increasing the processing time of rare earth polishing powder. Therefore, an efficient pressure filtration device for dehydrating rare earth polishing powder is proposed to facilitate the addition of an auxiliary vacuum water collection mechanism, use the vacuum negative pressure method to assist in recovering the water extruded from rare earth polishing powder, improve the flow rate of water, and at the same time increase the dehydration efficiency, thereby improving the use effect.
