Description

Technical Field

[0001] The utility model relates to the technical field of dichloropyrimidine crystallization, in particular to a stirring crystallization kettle. Background Art

[0002] The crystallization kettle is a crystallization equipment that requires refrigerated water or refrigerant water to rapidly cool down the interlayer after the material mixing reaction. The key links are the size of the interlayer area, the structural form of the agitator and the material outlet form. It is a mixed reaction equipment for domestic processes such as material mixing, heating, cooling and stirring in the chemical, pharmaceutical and food industries. Dichloropyrimidine is a white or light yellow powder. The dichloropyrimidine crystallization kettle is a device used for the production of mixed crystals of dichloropyrimidine; however, after the mixed reaction and crystallization of dichloropyrimidine in the crystallization kettle, a certain amount of gas is generated in the crystallization kettle through chemical reaction. The gas in the traditional crystallization kettle is manually discharged, which is inefficient. The excessive accumulation of gas in the crystallization kettle and the untimely discharge affect the production quality of dichloropyrimidine.

[0003] In the prior art patent CN213313438U discloses a dichloropyrimidine stirring crystallization kettle, in which the dichloropyrimidine raw material is stirred and mixed by rotating stirring blades, so that the dichloropyrimidine raw material is crystallized after reaction to prepare dichloropyrimidine, and the stirring efficiency of the dichloropyrimidine raw material is increased by four stirring blades in a U-shaped structure. When the rotating shaft rotates, the top block is driven to rotate and collides with the fixed block, and then the fixed block and the push rod are pushed to move away from the rotating shaft, and the partition is pushed to rotate and squeeze the torsion spring. At this time, the air guide pipe is connected with the crystallization kettle body, so that the gas generated by the reaction of the dichloropyrimidine raw material inside the crystallization kettle body enters the air guide pipe, and then enters the gas storage box from the air inlet pipe for storage, so as to prevent pollution caused by gas leakage.

[0004] However, in the above-mentioned prior art patent, during the stirring process of the dichloropyrimidine raw material in the crystallization kettle, part of the dichloropyrimidine raw material will be retained on the inner wall of the crystallization kettle, resulting in incomplete stirring. The retained raw material will affect the subsequent normal processing. Utility Model Content
