A lifting and stirring coprecipitation device for rare earth

Abstract

The invention relates to a co-precipitation settling device for rare earth, in particular to a liftable stirring type co-precipitation settling device for the rare earth. The liftable stirring type co-precipitation settling device for the rare earth can be adjusted and can perform liftable stirring on rare earth mixture liquid. The liftable stirring type co-precipitation settling device for the rare earth comprises a precipitation cylinder, supporting legs, a drainage pipe, a first valve, a discharge pipe, a second valve, a first bearing, a rotating pipe, a gasket, a second bearing, a lead screw, a nut and the like. The supporting legs are located under the precipitation cylinder, the supporting legs are connected with the precipitation cylinder, and the supporting legs are arranged in a left-right symmetric mode. The liftable stirring type co-precipitation settling device for the rare earth can be adjusted and can perform liftable stirring on the rare earth mixture liquid, the mixed reaction of the rare earth mixture liquid is uniform, the quality of generated rare earth carbonate is good, the improvement the quality of obtained products is facilitated, time and efforts are saved,and the structure is simple.

Description

technical field [0001] The invention relates to a coprecipitation device for rare earths, in particular to a liftable and stirring coprecipitation 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...

Problems solved by technology

[0004] In order to overcome that the existing co-precipitation devices for rare earths usually adopt a traditional fixed structure, which cannot be adjusted, so that the rare earth mixture liquid cannot be lifted and stirred, resulting in uneven mixing reaction of the rare earth mixture liquid, and the generated carbonic acid The quality of rare earth is low, which seriously affects the quality of the produced product. The technical problem of the present invention is to provide a lifting and stirring co-precipitation for rare earth that can be adjusted and can lift and stir the rare earth mixture liquid. device
