Description

Technical Field

[0001] The utility model relates to the technical field of mixing equipment, in particular to mixing equipment for rare earth smelting. Background Art

[0002] Rare earth smelting refers to the process of extracting high-purity rare earth elements or compounds from rare earth ores through a series of physical and chemical treatments. The rare earth smelting process requires the use of solutions such as liquid alkali, ammonium bicarbonate, soda, and sulfuric acid, and these solutions need to be mixed together. Due to the large number of solutions that need to be mixed, current mixing devices are not convenient for fully mixing multiple solutions.

[0003] In response to the above problems, the prior art proposes a mixing device for rare earth smelting with patent publication number CN220425088U. By setting a limit plate, a threaded rod and a hexagonal nut, stirring plates of different specifications and types can be limited and fixed according to the type of existing solution, so that the solutions inside the mixing tank can be completely mixed. Although it is convenient for mixing multiple solutions, the stirring speeds and temperatures required for mixing different solutions are different. Directly mixing multiple solutions together can easily reduce the mixing effect, thereby easily affecting the smelting effect of rare earths. Utility Model Content
