[0029] When the device is in use, rare earth precipitation liquid is injected into the device through the liquid inlet pipe 201. At this time, the slag discharge pipe 202 is in a closed state. Then, under the action of membrane filtration, solid-liquid separation is performed, thereby achieving solid-liquid separation of the rare earth liquid. At this time, the separated liquid will be discharged through the discharge pipe at the bottom of the device housing 1, while the solid will remain in the filter membrane barrel 2;

At the same time, the piston cylinder 5 will continuously reciprocate at the telescopic end under the action of the arcuate wall 102, and the surrounding liquid will be sucked in through the piston cylinder 5 and discharged through the nozzle 401, thereby completing the cleaning of the outer wall of the filter membrane barrel 2 and avoiding the accumulation of solid impurities on the outer wall of the filter membrane barrel 2 and causing blockage.

[0031] After the filtration is completed, the valve can be opened to discharge the solid impurities through the slag discharge pipe 202.

[0032] The utility model can continuously adjust the position of the nozzle 401 through the arrangement of the arc groove 101 and the arc wall 102, thereby cleaning the outer wall of the filter membrane barrel 2 and reducing the blockage of the filter membrane. At the same time, the piston cylinder 5 can suck in the liquid and continuously supply water to the nozzle 401, which is convenient for continuous use.
