Technical Field
[0001] This utility model relates to the field of drug preparation technology, specifically to an extraction device for the synthesis of difenidol hydrochloride. Background Technology
[0002] Difenidol hydrochloride, chemically named 1,1-diphenyl-4-(1-piperidinyl)-1-butanol hydrochloride, is the main component of dizziness cessation. Difenidol hydrochloride can improve vertebrobasilar insufficiency, dilate spasmodic blood vessels, regulate the vestibular nervous system, and inhibit abnormal impulses of the vestibular nervous system. Drug synthesis extraction is a process used in pharmaceutical production to extract components contained in a mixed original drug raw material solution.
[0003] To improve the concentration of extracted drugs, the drugs are often crushed before the components in the original drug raw material solution are extracted. However, since the blades used to crush the original drugs are often fixedly connected to the equipment, they are prone to becoming dull after long-term crushing work, which can affect the efficiency of subsequent crushing of raw materials. In addition, impurities in the extract are mostly filtered out by the filter screen. After the impurities are filtered out, they may get stuck in the filter pores, which can affect the subsequent filtration effect. Utility Model Content
[0004] To improve the concentration of extracted drugs, the drugs are often crushed before extraction of components from the original drug raw material solution. However, since the blades used to crush the raw drugs are often fixedly connected to the equipment, they tend to become dull over time, which can affect the efficiency of subsequent crushing of raw materials. Furthermore, impurities in the extract are often filtered out through a filter screen, and these impurities may become stuck in the filter pores after filtration, affecting the subsequent filtration effect. The purpose of this invention is to provide an extraction device for the synthesis of difenidol hydrochloride.
