Description

Technical Field

[0002] A continuous crystallizer refers to a device that can achieve continuous crystallization production compared with the traditional single-tank batch crystallization. Evaporative crystallization also belongs to the category of continuous crystallization, but usually refers to cooling crystallization or reaction crystallization equipment, that is, a crystallization device that can achieve continuous feeding, continuous discharging, and continuous filtration.

[0003] In order to improve the stirring efficiency of the existing crystallizer, it is found through retrieval that the patent publication number CN205965088U discloses a stirred crystallizer. The first connecting part and the second connecting part are used to connect the paddle blades. The first intermediate connecting part can ensure better structural strength of the support connecting frame. The first paddle blade is vertically distributed in the axial direction of the stirring shaft and the deflection angle is set at 30°, which can meet the up-and-down convection circulation and shearing ability of the material, and maximize the stirring of the material. However, during the liquid crystallization process, some crystals are likely to adhere to the inner wall of the crystallization cylinder. After crystallization, some crystals remain in positions that are difficult for the stirring frame to reach, which easily leads to crystals remaining in the crystallization cylinder, and thus easily affects the subsequent use of the crystallization cylinder.
