Description

Technical Field

[0001] This utility model relates to the field of extraction equipment technology, specifically to an extraction device for the separation of hafnium and zirconium. Background Technology

[0002] Zirconium is a metallic element, silvery-gray in color, hard, with a high melting point, and corrosion resistant. It is used to make alloys, flash powder, and as a degassing agent in vacuum environments. Tightly pressed pure zirconium is used as the lining material for uranium rods in nuclear reactors. Hafnium is also a metallic element. In nature, hafnium often occurs in association with zirconium; all zirconium-containing minerals contain hafnium. Hafnium and zirconium are isomorphous, with hafnium primarily found in zircon. Industrially used zircon contains 0.5%-2% HfO2. Secondary zircon ores, such as beryllium zircon, can contain up to 15% HfO2. There is also a metamorphic zircon, strobolith, which contains over 5% HfO2. The latter two minerals are scarce and not yet used industrially; hafnium is mainly recovered during zirconium production.

[0003] Existing extraction equipment, by incorporating a tank, shell, and stirring shaft, facilitates uniform mixing and thorough stirring of hafnium zirconium with the extractant. It also includes a scraper, heating device, and support plate to ensure uniform distillation of hafnium zirconium, thereby achieving the desired extraction effect.

[0004] However, existing extraction equipment generates a certain amount of gas during distillation. This gas is always inside the shell and is in constant contact with the mixture. After a period of time, it will return to the mixture, resulting in a decrease in the extraction effect of the mixture. To address the above problem, an extraction device for the separation process of hafnium and zirconium is proposed. Utility Model Content
