[0002] Synthetic drugs are drugs made by chemical synthesis or biosynthesis. Chemical synthesis includes organic synthesis and inorganic synthesis. Biosynthesis includes full biosynthesis and partial biosynthesis and partial chemical synthesis. Drug synthesis occupies an extremely important position in the pharmaceutical industry. Synthetic drugs are widely used in medical practice. The structure of some synthetic drugs is very similar to that of natural drugs, but not exactly the same. Extraction is to use the difference in solubility or distribution coefficient of a substance in two immiscible (or slightly soluble) solvents to transfer the substance from one solvent to another. After repeated extractions, most of the compounds are extracted. Extraction is needed to extract effective substances in the synthesis of chemical drugs.

[0003] However, the existing chemical drug synthesis extraction equipment generally stirs and mixes the two layers of immiscible liquid inside by means of a stirring device. The fluid stirring and mixing has a large mixing dead angle and causes the two layers of immiscible liquid inside to be uniformly mixed. Ordinary extraction equipment is not convenient enough to separate the two layers of liquid. It is not easy to separate the two layers of liquid completely during the separation operation, and the separation effect is poor. Based on this, the utility model designs a chemical drug synthesis extraction equipment to solve the above problems. Utility Model Content
