A rare earth processing device

Abstract

The present invention relates to a treatment device, in particular to a rare earth treatment device. The technical problem to be solved by the present invention is to provide a rare earth treatment device. A rare earth treatment device, including an insulated crucible, an electrolytic crucible, an electrode, a condensation separation device, a high-temperature purification device and a fluorine gas recovery device; a high-temperature purification device is provided at the top of the electrolysis chamber, and the left end of the high-temperature purification device is connected to the condensation separation device; A fluorine gas recovery device is installed at the right end of the electrolysis chamber. In order to solve the problem that when using the existing neodymium metal processing device, the neodymium metal remaining in the crucible during electrolysis must be separated from other auxiliary electrolysis raw materials through complicated methods, which consumes a lot of time. The invention achieves the effect of thoroughly drying the crystal water through the slow rotation of the "Ferris wheel", recovering fluorine gas externally to prepare hydrofluoric acid for glass etching, and finally recovering auxiliary raw materials, and the protection device creates additional value.

Description

Technical field [0001] The present invention relates to a treatment device, in particular to a rare earth treatment device. Background technique [0002] Neodymium is a silver-white metal with a melting point of 1024°C, a density of 7.004g / cm³, and paramagnetism. Neodymium is one of the most active rare earth metals. It can darken quickly in the air and form oxides. It reacts slowly in cold water and reacts quickly in hot water. Neodymium-doped yttrium aluminum garnet and neodymium glass can replace ruby ​​as laser materials, and neodymium and praseodymium glass can be used as goggles. With the birth of praseodymium, neodymium also came into being. The arrival of neodymium has enlivened the rare earth field, plays an important role in the rare earth field, and controls the rare earth market. One of the existing industrial methods for refining neodymium is to electrolyze a ternary mixture of neodymium oxide, neodymium fluoride and lithium fluoride. However, neodymium oxide ...

Problems solved by technology

[0004] In order to overcome the problem of using the existing neodymium metal treatment device, the present invention must use complex methods to separate the metal neodymium remaining in the crucible from other auxiliary electrolysis raw materials, which consumes a lot of time and sets more equipment, which increases the production cost; When preparing metal neodymium, the raw material neodymium oxide is very easy to combine with water in the air, and it is very difficult to separate the bound water after short-term drying. Neodymium oxide containing bound water will greatly reduce the efficiency of electrolysis, consume more electric energy, and improve the efficiency of electrolysis. Production cost; when preparing metal neodymium, the fluorine element in the auxiliary electrolytic raw material lithium fluoride and neodymium fluoride will be emitted in the form of fluorine gas, which is highly corrosive, but it is also a resource that can be recycled. Traditional preparation equipment Due to the lack of recycling devices, the disadvantage of being unable to recycle fluorine gas, the technical problem to be solved by the present invention is to provide a rare earth processing device
