Sublimation crystallization device for purity inspection of chemical components of traditional Chinese medicine preparation

Abstract

The invention discloses a sublimation crystallization device for purity inspection of chemical components of a traditional Chinese medicine preparation, the sublimation crystallization device comprises a sublimation crystallization device body, the sublimation crystallization device body comprises a crystallizer, a shell fixedly sleeving the crystallizer and a temperature thermocouple fixed at the top of the left side of the crystallizer, and the inner wall of the bottom of the crystallizer is arranged to be an arc-shaped mechanism. The crystallizer is provided with an automatic discharging mechanism, the automatic discharging mechanism comprises a discharging pipe which is communicated and fixed on the inner wall of the bottom of the crystallizer, the shell is fixedly arranged on the discharging pipe in a sleeving manner, a square rod is arranged in the discharging pipe, and the top end of the square rod extends into the crystallizer. The sublimation crystallization device is reasonable in design, crystallization materials in the crystallizer can be conveniently and automatically discharged, the crystallization materials attached to the inner wall of the crystallizer can be conveniently and automatically scraped and discharged, the purposes of automatic discharging and material scraping are achieved, time and labor are saved, the labor intensity is reduced, the discharging efficiency is improved, the use requirement is met, and use is facilitated.

Description

technical field [0001] The invention relates to the technical field of sublimation crystallization equipment, in particular to a sublimation crystallization device for testing the purity of chemical components of traditional Chinese medicine preparations. Background technique [0002] In the inspection of the purity of the chemical components of traditional Chinese medicine preparations, a sublimation crystallization device is needed to carry out sublimation crystallization of Chinese medicines. Unlike solution crystallization, the sublimation crystallization process is less affected by other molecules, and can directly change from a gaseous state to a solid crystal; [0003] After retrieval, Chinese Patent Application No. 201821852145.4 discloses a sublimation crystallization device for testing the purity of chemical components of traditional Chinese medicine preparations, including an oil heater, a sublimation kettle, a crystallization kettle and a cooling water tank, where...

AI Technical Summary

Problems solved by technology

[0004] The sublimation crystallization device disclosed in the above-mentioned patent still has some deficiencies in the use of a sublimation crystallization device for testing the purity of chemical components of traditional Chinese medicine preparations. ; and requires personnel to scrape and take out the crystallization material attached to the inner wall of the crystallizer), which is time-consuming and laborious, and the discharge efficiency is low, which cannot meet the needs of use. For these two points, further extension and improvement, so we proposed a A sublimation crystallization device for testing the purity of chemical components of traditional Chinese medicine preparations is used to solve the above problems
