Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of crystallization equipment, more particularly to an intelligent detection crystallizer. BACKGROUND

[0002] The crystallizer is a tank-shaped container, the wall of which is provided with a jacket or a pipe coil inside the container for heating or cooling the solution in the tank. The crystallization tank can be used as an evaporative crystallizer or a cooling crystallizer. In order to improve the production intensity of the crystal, a stirrer can be additionally arranged in the tank. The crystallization tank can be used for continuous operation or intermittent operation.

[0003] The existing Chinese invention patent (CN106422400A) discloses a crystallizer, which can effectively improve the liquid circulation rate in the crystallization equipment, and in turn improve the crystallization efficiency. The crystallizer comprises an upper chamber, a heat exchange chamber and a crystallization chamber connected in sequence from top to bottom. The crystallizer further comprises a flow guide pipe and an inclined plate. The flow guide pipe passes through the heat exchange chamber, and the inclined plate divides the crystallization chamber into a circulation chamber located at the upper part and a crystallization chamber located at the lower part. A circulation liquid inlet in communication with the circulation chamber is arranged at the lowest part of the circulation chamber, and a circulation liquid outlet in communication with the crystallization chamber is arranged at the highest part of the crystallization chamber. The circulation liquid inlet and the circulation liquid outlet are communicated through a circulation pipeline, and a circulation pump is arranged on the circulation pipeline. The circulation pump provides forced circulation power for the entire crystallizer, so that the liquid circulation rate in the crystallizer is fast and the circulation flow is large, thereby ensuring the crystallization efficiency of the entire crystallizer.

[0004] However, there are still some deficiencies in the use process. After the solution in the crystallization tank is crystallized, the crystalline particles are easily attached to the inner wall of the crystallization tank, which reduces the crystallization yield and makes it inconvenient to clean. Therefore, how to fully mix and stir the solution in the crystallization tank during the heating and evaporation crystallization process, and how to automatically control the device to scrape off the crystalline particles attached to the inner wall of the crystallization tank after the crystallization is completed to improve the yield of the crystal and avoid the blockage of the crystallization tank are problems that need to be solved.
