Description

Technical Field

[0001] The invention relates to the technical field of zirconium and hafnium extraction, in particular to zirconium and hafnium separation centrifugal extraction equipment. Background Art

[0002] Zirconium is a metallic element, symbol Zr (zirconium). It is silver-grey, hard, has a high melting point and is corrosion-resistant. It is used to make alloys, flash powder, etc. It is also used as a degassing agent in a vacuum. Tightly compressed pure zirconium is used as the outer jacket of uranium rods in nuclear reactors. Hafnium is also a metallic element. In nature, hafnium often coexists with zirconium. Zircon-containing minerals all contain hafnium. Hafnium and zirconium are isomorphous. Hafnium is mainly found in zircon. The amount of HfO2 in zircon used in industry is 0.5%-2%. The HfO2 content of beryllium zircon in secondary zircon ore can be as high as 15%. There is also a metamorphic zircon, qubikerite, which contains more than 5% HfO2. The reserves of the latter two minerals are small and have not yet been used in industry. Hafnium is mainly recovered in the process of zircon production.

[0003] In the prior art, centrifugal equipment is used in the extraction process of zirconium and hafnium to complete the extraction work. However, the traditional method is divided into multiple steps for processing. First, the zirconium and hafnium raw materials are mixed with the extraction liquid, and then centrifuged after mixing. After the mixing equipment operation is completed, manual cleaning is required. Therefore, multiple steps and different operations affect the extraction efficiency.

[0004] When applying for the present invention, the applicant found through searching that a Chinese patent disclosed an "extraction device in the process of separating hafnium and zirconium", and its application number is "202322956266.0". The patent is mainly through. By setting up a tank body, a shell and a stirring shaft, it is convenient to evenly mix the hafnium zirconium and the extracting liquid, and fully stir them. A scraper, a heating device and a supporting plate are set up to facilitate the uniform distillation of the hafnium zirconium, so as to achieve the extraction effect; however, the zirconium and hafnium separation process adopts a distillation method, and the zirconium and hafnium separation is divided into ore decomposition, zirconium and hafnium separation and extraction purification. The invention also needs subsequent reprocessing and extraction work, and the efficiency may not be improved. Therefore, according to the invention of the applicant, a method is invented that can complete the synchronous work of multiple processes for zirconium and hafnium separation, which improves the problem of low extraction efficiency of zirconium and hafnium separation.
