The working principle of the utility model is: the material enters the body of the crystallization tank from the feed port, and the cooling water is passed into the cooling jacket to cool down the body of the crystallization tank. Turn on the stirring motor to stir the material to cool down the material evenly. The scraper rotates with the stirring shaft to scrape off the grains attached to the inner wall of the tank. During the crystallization process, the multiple partition tanks are divided into upper and lower layers, and the crystallization is carried out on the upper layer of the tank. When more and more crystal grains are precipitated in the material, which will affect the stirring and heat conduction in the tank, turn on the material distribution motor, and the material distribution motor will drive the second rotating shaft connected to it to rotate, and the other second rotating shafts will move in the same direction due to the pull of the connecting rod. With the rotating movement, the partition connected to the second rotating shaft turns over, and the materials and grains on it fall into the distribution tank. After the material and crystal grains fall into the material distribution tank, reverse the material distribution motor to return the partition to the initial position. At this time, turn on the material liquid circulation pump to pump the material liquid in the material into the upper layer of the crystallization tank for re-crystallization . The partitions are sealed and connected through the first groove and the sealing plate in the second groove, which can prevent the feed liquid from leaking into the distribution tank from the crystallization tank.

The utility model separates the crystal grains during the crystallization process, on the one hand, it avoids the crystal grains from adhering to the inner wall of the crystallization tank to affect the thermal conductivity, and reduces the energy loss; , improve the crystallization efficiency, and improve the crystallization effect.
