Description

TECHNICAL FIELD

[0001] The utility model relates to crystallization device technical field, concretely is a chemical medicine crystallization device. BACKGROUND

[0002] At present, the research on various elements is more and more in-depth, and the use of chemical medicine is more and more skilled in production activities. In the processing of chemical medicine, it needs to go through multiple processes, among which the purpose of the crystallization step is to improve the purity of the medicine. Crystallization needs to stir and cool the mother liquor, and then cool it to make the crystals precipitate naturally

[0003] The prior art patent document with the publication number CN222400306U provides a chemical medicine crystallization device, which comprises a base, a support column, a stirring barrel, the support column is welded to the top outer wall of the base, and is provided with a stirring rod, an arc-shaped groove, an outer cylinder, a matching rod two, an inner cylinder, a positioning head, a rotating plate, and a scraper. When in use, the motor two can drive the stirring rod to rotate, and the inner cylinder can intermittently drive the rotating plate to rotate under the cooperation of the matching rod two and the arc-shaped groove, and then the scraper can intermittently scrape the inner wall of the stirring barrel to avoid adhesion during crystallization. The utility model can avoid crystal adhesion, and is provided with a guide plate, a toothed plate, a matching rod three, an arc-shaped ring, a clamping block and a gear. When the stirring rod rotates to stir and crystallize, the arc-shaped ring first contacts the matching rod three, and then the toothed plate slides reversely under the meshing of the gear. The clamping block cancels the clamping of the positioning head. After the rotation is finished, the toothed plate is reset, the clamping block clamps the positioning head, and the inner cylinder cannot accurately drive the rotating plate to rotate.

[0004] However, the existing chemical medicine crystallization device usually needs to heat the crystals during use, and then needs to cool and crystallize after heating. However, during the cooling and crystallization process, air cooling or water cooling is usually used. However, when water cooling is performed, a large amount of heat is absorbed by the water during the cooling process, and the temperature of the water rises, resulting in the need for continuous supply and discharge of cooling water. Since the chemical medicine crystallization device cannot cool the water, the cooling water cannot be recycled, which is not conducive to water resource conservation and increases the cost of crystallization. Therefore, we propose a chemical medicine crystallization device. UTILITY MODEL CONTENTS
