Problems solved by technology

[0003] Rare earth is the general term for seventeen metal elements including lanthanides, scandium and yttrium in the chemical periodic law. The waste liquid generated during the separation and production of rare earth materials and liquids generally includes extraction waste liquid and oxalic acid precipitation waste liquid. There are a small amount of rare earth elements that exist in ionic state. If these rare earth elements are not recovered, the loss of rare earth resources will result. The oxalic acid precipitation waste liquid is produced by rare earth elements and oxalic acid to form oxalic acid rare earth precipitation process. It contains some rare earth salts. If it is not recycled, it will also cause the loss of a large amount of rare earth elements, but the traditional method of recycling rare earths will have a large amount of impurities attached, which seriously affects the quality of recycled rare earths
[0004] In the prior art, the patent with the publication number CN108159749A discloses a convenient cleaning type recycling and processing device for rare earth waste liquid, including a filter cylinder, cleaning device, conveying and cleaning device, filter screen, L-shaped connecting rod, positioning Bolts, outriggers, bases, outlet pipes and valves Ⅰ; the lower part of the filter tank is equipped with a cleaning device, the left side of the filter tank is equipped with a conveying and cleaning device, and a filter screen is installed inside the filter tank to realize the cleaning of the filter tank , but no deep cleaning of the filter

Abstract

The invention relates to a treatment device, in particular to a convenient-to-clean recovery treatment device for rare earth waste liquid. The invention provides the convenient-to-clean recovery treatment device for the rare earth waste liquid, and the device can improve the filtering efficiency of the rare earth waste liquid and deeply clean a filter screen. The convenient-to-clean recovery treatment device for rare earth waste liquid comprises a base, a workbench arranged on the base, a pushing mechanism arranged on the workbench, a moving mechanism arranged in the middle of the workbench ina sliding manner, a material storage frame arranged on the moving mechanism, and a scraping mechanism arranged on one side of the workbench. Through the design of the pushing mechanism and the cooperation with the moving mechanism, residues left on a filter screen can be removed more easily, and rare earth waste liquid can be cleaned more cleanly; and through the design of the moving mechanism, the material storage frame can be moved, and residues on the filter screen can be completely removed under the cooperation of the material storage frame and the scraping mechanism.

Description

technical field [0001] The invention relates to a processing device, in particular to a convenient cleaning recovery processing device for rare earth waste liquid. Background technique [0002] The processing device is a device for directional processing of objects. [0003] Rare earth is the general term for seventeen metal elements including lanthanides, scandium and yttrium in the chemical periodic law. The waste liquid generated during the separation and production of rare earth materials and liquids generally includes extraction waste liquid and oxalic acid precipitation waste liquid. There are a small amount of rare earth elements that exist in ionic state. If these rare earth elements are not recovered, the loss of rare earth resources will result. The oxalic acid precipitation waste liquid is produced by rare earth elements and oxalic acid to form oxalic acid rare earth precipitation process. It contains some rare earth salts.
