Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal extractor fixing, in particular to a centrifugal extractor fixing device for zirconium and hafnium production. Background Art

[0002] Centrifugal extractors, also called separation centrifuges, are commonly used in zirconium and hafnium production. Centrifugal extractors use the principle that materials fall into different layers at different sedimentation speeds under the action of centrifugal force to separate different components in a mixture. In zirconium and hafnium production, centrifugal extractors can be used to separate and extract mixtures containing zirconium and hafnium, thereby purifying and refining zirconium and hafnium. The working principle of a centrifugal extractor is to use centrifugal force to decompose the mixture into components of different densities, and to separate different components by adjusting the rotation speed and working parameters. In zirconium and hafnium production, centrifugal extractors are usually used in conjunction with specific solvents and extractants to separate other impurities and waste materials from the mixture containing zirconium and hafnium, thereby extracting pure zirconium and hafnium products. When installing the centrifugal extractor, a fixing device is required to fix the centrifugal extractor.

[0003] The existing fixing devices of centrifugal extractors are mostly provided with a base at the bottom of the centrifugal extractor. The setting is relatively simple and the stability of the overall structure of the centrifugal extractor is poor. During the long-term operation of the centrifugal extractor, the connection between the centrifugal extractor and the external pipeline is easily affected by the vibration of the centrifugal extractor itself and becomes loose, which makes it inconvenient to use the fixing device to fix the centrifugal extractor for long-term use. Moreover, when the centrifugal extractor is working, its own vibration makes the overall stability of the centrifugal extractor poor, and the simple base setting makes the centrifugal extractor prone to loosening and deflection after long-term operation, thereby affecting the long-term stable operation of the centrifugal extractor. For this reason, we propose a fixing device for a centrifugal extractor for zirconium and hafnium production. Utility Model Content
