Abstract

The invention discloses a crystallizer for a lithium hydroxide purification product. The crystallizer comprises a shell provided with a support frame, wherein a crystallization plate is arranged in the shell; the section of the crystallization plate is in a downward cone shape; a leakage port is formed in the center of the crystallization plate; a cavity is formed in the inner wall of the shell; asecond cavity communicating with a first cavity is formed in the crystallization plate; the first cavity and the second cavity are both filled with water; a heating mechanism for heating the water inthe first cavity and the second cavity is arranged on the shell; a rotating rod is arranged in the shell in a rotating manner; a plurality of stirring rods are fixedly connected to the periphery of the rotating rod; a driving mechanism for driving the rotating rod to rotate is arranged on the shell; and a cleaning and scraping structure is arranged in the shell. The crystallizer of the inventionis reasonable in structure; crystal substances can be conveniently guided out after crystallization, and the phenomena of adhesion and blockage are avoided; and heating effect is stable, so a temperature is constant, and crystallization effect is guaranteed.

Description

technical field

[0001] The invention relates to the technical field of lithium hydroxide purification, in particular to a crystallizer for lithium hydroxide purification products. Background technique

[0002] High-purity lithium hydroxide is an important source of lithium, and it is widely used in high-tech fields such as new energy and new materials. During the purification and preparation of lithium hydroxide, it is often necessary to go through multiple crystallization operations to improve the purity of lithium hydroxide. Generally, during the crystallization process of lithium hydroxide, the influence of temperature is small, but in the case of relatively high purity The effect is more important when the crystallization of lithium hydroxide is high.

[0003] The existing crystallizers are often heated directly by installing a heating device outside the container, and the internal position used to accept the crystallization may not be able to conduct heat well, resulti...
