Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rare earth metal oxide production, in particular to a preparation device of rare earth metal oxide. BACKGROUND

[0002] The production of rare earth metals is also called rare earth pyrometallurgical production. Rare earth metals are generally divided into mixed rare earth metals and single rare earth metals. The composition of mixed rare earth metals is close to the original rare earth components in the ore, and single metals are refined metals of each rare earth. It is difficult to reduce rare earth oxides (except for samarium, europium, ytterbium and thulium oxides) into single metals by general metallurgical methods because of their high heat generation and high stability. Therefore, the raw materials commonly used in the production of rare earth metals at present are their chlorides and fluorides.

[0003] At present, the method of vacuum thermal reduction is generally used to prepare metals with low impurities and high purity. Generally, rare earth oxides are first prepared into rare earth fluorides, and then reduced by calcium in a vacuum induction furnace to obtain crude metal, which is then remelted and distilled to obtain relatively pure metal. This method can produce all single rare earth metals. The vacuum induction furnace is an electric furnace that uses the inductive heating effect of the material to heat or melt the material. The high-temperature molten metal produced by the vacuum induction furnace is poured into a crucible through a guide slot on one side of the vacuum induction furnace for further smelting. During the pouring and unloading process, some waste materials will stick to the wall of the guide slot. The existing method is to wait for the guide slot to cool down, then the worker wears a mask with high filtration effect, and then uses a shovel to remove the residue close to the guide slot. Since the temperature near the vacuum induction furnace is high, manual cleaning will cause the worker to be very close to the vacuum induction furnace, which has certain safety hazards. Therefore, we propose a preparation device for rare earth metal oxides. SUMMARY
