A sublimation crystallization device for testing the purity of chemical components of traditional Chinese medicine preparations

Abstract

The invention discloses a sublimation crystallization device for testing the purity of chemical components of traditional Chinese medicine preparations, comprising a sublimation crystallization device body. The temperature measuring thermocouple at the top of the side, the bottom inner wall of the crystallizer is set as an arc mechanism, the crystallizer is provided with an automatic discharging mechanism, and the automatic discharging mechanism includes a connected and fixed on the bottom inner wall of the crystallizer. The discharge pipe, the shell is fixedly sleeved on the discharge pipe, and a square rod is arranged in the discharge pipe, and the top end of the square rod extends into the crystallizer. The design of the invention is reasonable, it is convenient to automatically discharge the crystallized material in the crystallizer, and it is convenient to automatically scrape and discharge the crystallized material adhered to the inner wall of the crystallizer, so as to realize the purpose of automatic discharging and scraping, and save time and effort. , reduce labor intensity, improve discharge efficiency, meet the needs of use, and is conducive to use.

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 required to sublime and crystallize the traditional Chinese medicine. The sublimation crystallization is different from the solution crystallization, and the crystallization process is less affected by other molecules, and can be directly changed 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 a thermal oil heater, a sublimation kettle, a crys...

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
