Description

Technical field [0001] The present invention relates to the field of rare earth recovery, and in particular, to a dissolved oxidation apparatus for rare earth oxides recovering rare earths. Background technique [0002] Rare Earth is a syndrome of a total of 17 chemical elements of Group III Part III elements, yttrium and lanthanide elements. Generally, in the form of oxide, it belongs to non-renewable resources. Rare earth becomes useful materials, complicated procedures, cumbersome and cost high therefore name "rare earth". Therefore, the recovery of rare earth oxides is one of the important means of saving rare earth resources. Rare earth oxides are dissolved in the recovery process to be a prerequisite step. [0003] China Patent No. CN108165739B announces a dissolved oxidation device for rare earth oxide recovery rare earth. The technical problem to be solved by the present invention is to provide a process capable of carrying out dissolved and oxidation of recovered rare ea...

AI Technical Summary

Problems solved by technology

However, the above-mentioned patents still have the following deficiencies in use, first; the above-mentioned patents cannot be effectively heated and kept warm when in use, and rare earth oxides can be heated to a certain temperature when they are dissolved and oxidized. Therefore, the above-mentioned patent function is insufficient

Second; the above patents do not have a corresponding cleaning mechanism after use, making it difficult to clean the equipment

Thirdly, new precipitates will be formed during the dissolution and oxidation of rare earth oxides, and the precipitates need to be separated from the solution. There is no quick separation mechanism in the above-mentioned patents, and the function is single
