[0002] The lithium in salt lakes is generally extracted from the old brine left over after the production of sodium and potassium. The steps for extracting lithium from different types of salt lakes are basically the same. The old brine is enriched with lithium and then evaporated, magnesium removed, and concentrated to extract lithium ions to produce lithium carbonate.

[0003] In the prior art, the extraction of lithium carbonate from salt lake brine by a device for extracting lithium carbonate from brine generally adopts an evaporation concentration method. However, during the concentration process, due to uneven heating and expansion between the liquid and the inner wall of the vessel, it is easy to cause solution crystals to cover the surface of the inner wall. After the crystals are formed, they are usually in a lumpy shape, which is not easy to clean and remove. It is impossible to effectively remove impurities and contaminants from the input materials, affecting the purity and quality of the concentrated liquid.
