Device for efficiently extracting rare earth metal by utilizing extracting neodymium-iron metal scraps

Abstract

The invention relates to a rare earth metal extraction device, in particular to a device for efficiently extracting rare earth metal by utilizing extracting neodymium-iron metal scraps. The invention provides the device for efficiently extracting the rare earth metal by utilizing the extracting neodymium-iron metal scraps, which simplifies the purification operation by automatically releasing an extracting agent, automatically stirring mixed solution and automatically heating and separating out rare earth metal crystals. The device for efficiently extracting the rare earth metal by utilizing extracting neodymium-iron metal scraps comprises a stirring barrel, a sliding sleeve, a stirring assembly, a fixed column and a feeding pipe; the sliding sleeve is arranged at the top of the stirring barrel; the stirring assembly is arranged on the sliding sleeve in a sliding mode; the fixed column is arranged at the top of the stirring barrel and matched with the stirring assembly in a contact mode; and the feeding pipe is arranged at the top of the stirring barrel. According to the invention, by arranging a fixing and supporting mechanism, a stable supporting effect on the stirring barrel is achieved, and the overall stability of the device is enhanced.

Description

technical field [0001] The invention relates to a rare earth metal extraction device, in particular to a device for efficiently extracting rare earth metals by extracting neodymium-iron metal waste. Background technique [0002] Rare earth metals, also known as rare earth elements, are the general term for 17 elements of scandium, yttrium, and lanthanide in group IIIB of the periodic table of elements. Rare earth metals and rare metal alloys can be deoxidized and desulfurized in steelmaking, so that the content of both can be reduced to less than 0.001%, and the shape of inclusions can be changed to refine the grains, thereby improving the processing performance of steel, increasing strength and toughness , corrosion resistance and oxidation resistance, etc., which can improve the casting process and improve the mechanical properties of cast iron. However, most of the rare metals mined naturally have impurities, and the impurity content has a great influence on their proper...
