A multi-mode stirring co-precipitation device for rare earth

Abstract

The invention relates to a co-precipitation precipitation device for rare earth, in particular to a multi-mode stirring type co-precipitation precipitation device for the rare earth. To solve the technical problem of providing the multi-mode stirring type co-precipitation precipitation device, capable of being adjusted and stirring rare earth mixture liquid in various ways, for the rare earth, thetechnical scheme of the multi-mode stirring type co-precipitation precipitation device for the rare earth is that the multi-mode stirring type co-precipitation precipitation device for the rare earthcomprises various parts such as a base, a first bearing, a support shaft, a cylinder, a drain pipe, a first valve, a filter screen, a discharge pipe, a second valve, a second bearing and long connecting shaft; the first bearing is embedded in the base; the lower end of the support shaft and the first bearing are in interference connection. The multi-mode stirring type co-precipitation precipitation device for the rare earth has the advantages of being easy to adjust and capable of stirring the rare earth mixture liquid in various ways, realizing uniform mixing reaction of the rare earth mixture liquid, having simple structure, easy operation and low labor intensity, and being time-saving and labor-saving.

Description

technical field [0001] The invention relates to a co-precipitation device for rare earths, in particular to a multi-mode stirring co-precipitation device for rare earths. Background technique [0002] Rare earths are known as "industrial vitamins". Now it has become an extremely important strategic resource. Rare earth element oxides refer to oxides of 15 lanthanide elements with atomic numbers from 57 to 71 in the periodic table of elements, and oxides of scandium and yttrium, a total of 17 elements whose chemical properties are similar to lanthanide elements. Rare earth elements have been widely used in petroleum, chemical industry, metallurgy, textile, ceramics, glass, permanent magnet materials and other fields. With the advancement of science and technology and continuous breakthroughs in application technology, the value of rare earth oxides will increase. The term rare earth is a name left over from history. Rare earth elements have been discovered since the end of...
