Description

TECHNICAL FIELD

[0001] The utility model relates to carbonic acid lithium preparation device technical field, specifically, relate to a carbonic acid lithium extraction is with stationary separation device. BACKGROUND

[0002] As an important lithium compound, lithium carbonate has a wide range of applications in battery manufacturing, ceramic industry, glass manufacturing and other fields. With the rapid development of new energy industry, especially the increasing demand for electric vehicles and energy storage systems, the demand for battery-grade lithium carbonate has also increased significantly. In the preparation process of lithium carbonate, extraction is a key step. Extraction technology can effectively extract target compounds from complex solutions while removing impurities. In the extraction process of lithium carbonate, organic solvents are usually used as extractants to react with lithium ions in the lithium carbonate solution to form extractable compounds. However, the solution after extraction often contains multiple components, which need to be further purified by stationary separation.

[0003] Stationary separation is a physical separation method based on density difference. In the extraction process, the compounds formed by the extractant and the target compound have different densities from the unreacted extractant, solvent, etc. They will naturally separate during the stationary process.

[0004] When performing extraction stationary separation operation, it is usually performed in the corresponding extraction stationary separation device. The stationary separation devices on the market generally only have a pipeline at the bottom. During the separation operation, the corresponding layered liquids need to be sequentially discharged outward along the pipeline in the top-down order. However, when the upper liquid needs to be taken, the liquid will be attached to the inner wall of the pipeline after being discharged from the bottom layer, which will cause contamination of the upper liquid when the upper liquid is discharged subsequently. This is not conducive to achieving the effect of directly pumping and discharging the upper liquid needed from the top. In view of this, we propose a stationary separation device for lithium carbonate extraction. UTILITY MODEL CONTENTS
