Description

Technical Field

[0001] The utility model relates to the technical field of drug production and processing, in particular to a crystallization tank for drug production. Background Art

[0002] Drugs refer to chemical substances that can affect the physiological functions of body tissues and organs and the metabolic process of cells, and are used for the prevention, treatment, diagnosis of diseases and family planning. There are many types of drugs, including but not limited to antibiotics, antiviral drugs and Chinese patent medicines. The mechanism of action of a drug refers to the biological mechanism by which the drug acts in the body, including target action, metabolic action, reaction action and physiological action. In the process of drug production and processing, in order to improve the purity of the drug, enhance stability and improve the efficacy, the drug needs to be crystallized, and the crystallization operation of the drug requires the use of a crystallization tank.

[0003] Common crystallization tanks for drug production are usually composed of structures such as tank bodies, jackets, stirring devices, inlet and outlet ports, and temperature monitoring devices. After the drug solution is heated, stirred, and other treatments, it is crystallized by controlling the temperature and other conditions in the crystallization tank to crystallize the drug in the solution. This is a common crystallization tank structure and usage for drug production. In traditional drug production crystallization tanks, part of the crystallized material will be adsorbed on the inner wall of the tank, making it inconvenient to clean up the adsorbed crystals in the tank. For example, patent number CN218740317U is a drug production crystallization tank, and the cooperation of the stirring block drives the scraper to scrape off the material bonded to the inner wall of the crystallization tank body. However, in this way, since the crystallized material has a certain adsorption viscosity, when in contact with the scraper, part of the crystallized material will be adsorbed and adhered to the scraper surface, and the crystallized material on the scraper surface cannot be cleaned, and the next batch of materials will be contaminated during processing, resulting in the production quality and safety of the next batch of materials after crystallization, causing the drug crystals to be unable to be used, and the phenomenon of cost increase occurs, so a drug production crystallization tank is proposed.

[0006] (II) Technical solution

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a crystallization tank for drug production, comprising:

[0008] A tank shell, and an upper cover plate arranged on the top of the tank shell, and a lower base plate is added to the bottom of the tank shell;

On the one hand, the materials adsorbed on the scraper can be cleaned to avoid affecting the crystallization quality of the next batch of materials; on the other hand, the upper and lower scrapers can effectively prevent the materials adsorbed on the inner wall of the tank shell from being adsorbed on the inner wall of the lower bottom plate when falling, which is inconvenient to clean.

[0014] Preferably, connecting rods are transversely provided on the upper part, the center and the lower part of the inner side surface of the lower scraper, and the inner ends of the connecting rods are respectively connected to the corresponding parts of the outer surface of the second rotating shaft. The lower scraper drives the second rotating shaft to rotate in the same direction through the connecting rods.

When the lower slide plate descends along the lower scraper, under the action of the second telescopic rod and the second extrusion spring, it fits tightly between the front and rear ends of the inclined lower scraper, thereby ensuring the comprehensive removal of the adsorbed materials on the lower scraper.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a crystallization tank for drug production, which has the following

[0018] Beneficial effects:

[0019] The crystallization tank for drug production drives the upper scraper and the lower scraper to rotate through the first rotating shaft and the second rotating shaft.

In this way, on the one hand, the materials adsorbed on the scraper can be cleaned to avoid affecting the crystallization quality of the next batch of materials; on the other hand, the upper scraper and the lower scraper can effectively prevent the materials adsorbed on the inner wall of the tank shell from being adsorbed on the inner wall of the lower bottom plate when falling, which makes it inconvenient to clean.
