Description

Technical Field

[0001] The utility model relates to the technical field of lithium carbonate processing, in particular to a centrifuge for lithium carbonate production. Background Art

[0002] Lithium carbonate is a colorless monoclinic crystal with a melting point of 720 degrees Celsius. It is soluble in water and dilute acid, but insoluble in ethanol and acetone. Its thermal stability is lower than that of carbonates of other elements in the same group in the periodic table. It does not deliquesce in the air and can be obtained by adding sodium carbonate to lithium sulfate or lithium oxide solution. Its aqueous solution can be converted into an acid salt by passing carbon dioxide into it, which releases carbon dioxide when heated to form lithium carbonate. The aqueous solution is hydrolyzed when boiled and is generally used as a raw material for ceramics, glass, ferrites, etc.

[0003] In the production process of lithium carbonate, it is generally necessary to wash, centrifuge and dry to obtain the finished lithium carbonate product. At this time, a centrifuge for lithium carbonate production is needed.

Impurities will be adhered to the outer wall and inner wall of the centrifugal screen cylinder processed in the centrifuge, and the drying speed is slow. The temperature increase of the centrifuge during the centrifugation process will have a certain impact on the lithium carbonate. Therefore, a centrifuge for lithium carbonate production is proposed to address the above problems. Utility Model Content
