Problems solved by technology

[0005] In order to overcome the current problem of dissolving rare earth waste by acid leaching solution, the present invention usually does not mix the two substances, but directly pours the acid leaching solution into the rare earth waste treatment frame, so that the rare earth waste and the acid leaching solution Can not be fully contacted, resulting in slow dissolution rate and low working efficiency. The technical problem to be solved by the present invention is to provide a rare earth waste material that can mix the rare earth waste material and the acid leaching solution, increase its dissolution rate, and have high working efficiency. Pickling equipment for recovery and refining

Abstract

The invention relates to pickling equipment for refining, in particular to the pickling equipment for rare earth waste recycling and refining. According to technical scheme, the pickling equipment for rare earth waste recycling and refining can mix rare earth waste and an acid pickling solution, improves the dissolution speed of the rare earth waste and is high in working efficiency. The pickling equipment for rare earth waste recycling and refining comprises a discharging pipe, a valve, an acid pickling tank, a first rotating shaft, a mounting frame, stirring blades, a second rotating shaft, a first bearing seat, a side plate, a mounting plate, a material blocking cylinder and the like. The acid pickling tank is welded to the lower portion of the right side face of the side plate and in an opening type. According to the pickling equipment for rare earth waste recycling and refining, waste is loosened preliminarily through crushing teeth, accordingly, the waste treating speed in the follow-up treatment is accelerated, and meanwhile, the stirring blades are rotated.

Description

technical field [0001] The invention relates to pickling equipment for refining, in particular to pickling equipment for recycling and refining rare earth waste. 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. [0003] Some waste residues produced in the production of rare earths contain a lot of valuable elements, and usually ne...
