Description

Technical Field

[0001] The utility model relates to the technical field of stirring, in particular to a stirring device for catalytic reaction of pharmaceutical intermediates. Background Art

[0002] The so-called pharmaceutical intermediates are actually some chemical raw materials or chemical products used in the process of drug synthesis. This kind of chemical product does not require a drug production license and can be produced in ordinary chemical plants. As long as it reaches a certain level, it can be used in the synthesis of drugs.

[0003] At present, the pharmaceutical intermediate catalytic reaction stirring device in the prior art usually adds the pharmaceutical intermediate into a stirring barrel and stirs it through a stirring structure. During stirring, since most of the pharmaceutical intermediates are in powder form, the stirring structure cannot thoroughly stir the pharmaceutical intermediates, so that the pharmaceutical intermediates cannot be evenly mixed. There is a problem that the pharmaceutical intermediates cannot be evenly mixed, and when the stirring is completed, the inside of the stirring device cannot be cleaned, and some pharmaceutical intermediates will remain in the stirring device and be mixed in the pharmaceutical intermediates to be stirred next time. Pharmaceutical intermediates are medicines, most of which are used on the human body. After stirring, the pharmaceutical intermediates contain other medicines, which is easy to cause accidents. There is a problem that the inside of the stirring device cannot be thoroughly cleaned. Utility Model Content
