The invention relates to a device for extracting rare earth, in particular to a device for extracting rare earth metal by using a vacuum distillation method. The device for extracting the rare earth metal by using the vacuum distillation method provided by the invention can efficiently remove some impurities in the rare earth metal, the purity of the extracted metal is relatively high, and equipment is simple. The device for extracting the rare earth metal by using the vacuum distillation method comprises a first supporting frame, a heating mechanism, a supporting mechanism, a first baffle, and a sucking pump, wherein the heating mechanism is arranged on the first supporting frame; the supporting mechanism is arranged between the heating mechanism and the first supporting frame; the first baffle is arranged on the upper side of the supporting mechanism; and the sucking pump is arranged on the lower side of the first baffle. According to the device for extracting the rare earth metal by using the vacuum distillation method provided by the invention, through arranging the heating mechanism and the supporting mechanism, the heating mechanism operates to heat liquid rare earth on the supporting mechanism, so that metal in the rare earth can be distilled and extracted in a high-temperature vacuum state, and the purpose of heating is achieved.
Description
technical field [0001] The invention relates to a device for extracting rare earth, in particular to a device for extracting rare earth metal by vacuum distillation. Background technique [0002] Rare earth is the general term for seventeen metal elements including lanthanides, scandium and yttrium in the chemical periodic table. There are 250 kinds of rare earth ores in nature. Rare earth elements play an important role in my country's economic development. With the continuous advancement of science and technology , the demand for rare earth metals is increasing. At present, the extraction methods of rare earth metals include vacuum distillation or sublimation and regional smelting. Vacuum distillation is suitable for removing low vapor pressure impurities in rare earth metals and the difference in vapor pressure between rare earth metals to be purified. For large impurities, the extraction time of the existing equipment for extracting rare earth metals by distillation is too...
