Rare earth purification equipment for rare earth collection

Abstract

The invention relates to rare earth purification equipment, in particular to rare earth purification equipment for rare earth collection. The invention provides rare earth purification equipment for rare earth collection. The equipment is large in distillation contact area and capable of comprehensively taking out rare earth. The rare earth purification equipment for rare earth collection comprises a bottom frame, a heating barrel and a hopper, wherein the heating barrel is arranged on the bottom frame, the hopper is arranged on the heating barrel, a stirring mechanism is arranged on the heating barrel, and a discharging mechanism is arranged on the lower portion of the heating barrel. By arranging the stirring mechanism and the discharging mechanism, the discharging mechanism can control distilled rare earth to flow out, the stirring mechanism can uniformly stir the rare earth, and the effect of improving the rare earth distillation effect is achieved; by arranging the feeding mechanism and the vibration mechanism, as the hopper is located below the first motor, rare earth can be poured into the feeding mechanism more conveniently, the vibration mechanism can knock off the rare earth left on the inner wall of the heating barrel in a vibration mode, so that the purpose of preventing rare earth waste is achieved.

Description

technical field [0001] The invention relates to a rare earth purification equipment, in particular to a rare earth purification equipment for rare earth collection. Background technique [0002] The demand for high-purity rare earth metal materials is increasing day by day. The rare earth purification processing technology includes vacuum distillation, vacuum smelting, molten salt extraction, etc. Among them, the essence of vacuum distillation is distillation to sublimation, using the difference in vapor pressure of each element to purify rare earth metals under vacuum conditions. This method requires a higher vapor pressure for the purification of metals to facilitate the distillation or sublimation rate for practical applications, and it must be carried out at a temperature lower than the co-distillation or sublimation of its oxides, mainly for heavy rare earth metals The purification method has low cost and high efficiency, so this technology is one of the rare earth pur...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of rare earth purification equipment for rare earth collection that has a larger distillation contact area and can more comprehensively remove rare earths, so as to solve the problem in the above background technology that the existing distillation has a small distillation surface area and insufficient distillation speed. The condensation rate is higher than the distillation rate, resulting in reflux, and a small part of the purified rare earth metal will remain in the container, making it difficult to take out the problem
