Description

TECHNICAL FIELD

[0001] The utility model relates to lithium phosphate processing technical field, specifically, relates to a lithium extraction device for lithium phosphate preparation. BACKGROUND

[0002] In the production and preparation process of lithium phosphate, the mixing of raw materials and solid-liquid separation are two important links, which directly affect the quality and production efficiency of the product. In the traditional lithium extraction process, the mixing of raw materials usually depends on the one-way rotating stirring device in the reaction kettle. Although this stirring method can achieve basic mixing effect, the mixing efficiency is relatively low, and it is difficult to ensure the full and uniform mixing of raw materials. In addition, the solid-liquid mixture after mixing needs to be taken out manually and transferred to another separation device for separation treatment. This process not only consumes time and effort, increases production cost, but also may introduce impurities due to improper human operation, affecting the purity of the product. Therefore, we propose a lithium extraction device for lithium phosphate preparation to solve the above problems. SUMMARY
