Crude heparin sodium precipitation equipment

Abstract

The invention discloses crude heparin sodium precipitation equipment, relates to the technical field of crude heparin sodium refining, and aims to solve the problems that the existing crude heparin sodium raw material is generally placed in a precipitation tank during low-power precipitation, but the tank body is generally of a slender structure to be conveniently matched with a stirring shaft to mix materials in consideration of mixing uniformity, the container enables the raw materials to be easily influenced by end effect and interference settlement in the subsequent precipitation process, and the precipitation efficiency is reduced. A first rack is mounted above one side of the collecting box placing plate, a second rack is mounted above the other side of the collecting box placing plate, an electric control box is mounted on the outer wall of the second rack, a belt protection cover is mounted on the outer wall of the first rack, a stirring chamber is arranged between the first rack and the second rack, and the two sides of the stirring chamber are rotationally connected with the first rack and the second rack through transmission shafts.

Description

technical field [0001] The invention relates to the technical field of refining crude heparin sodium, in particular to crude heparin sodium precipitation equipment. Background technique [0002] Heparin sodium is the glycosaminoglycan compound with the most complex molecular structure known so far. Currently, the clinically applied products include heparin sodium and a series of low-molecular-weight heparins, and the required raw materials can only be extracted from the pig small intestinal mucosa. The raw material of heparin API is crude heparin, which can only be extracted from the small intestinal mucosa of healthy pigs. Because it contains a large amount of impurities such as impurity protein, impurity nucleic acid, microorganisms, etc., it needs to undergo physical and chemical extraction and separation processes to obtain directional heparin with complete natural structural groups. Heparin, so as to make heparin bulk medicine. In the refining process of crude heparin ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide heparin sodium crude product precipitation equipment to solve the problem that the existing heparin sodium crude product raw material proposed in the above background technology is usually placed in a precipitation tank for low-magnification precipitation, but the tank body is usually placed in a precipitation tank considering the uniformity of mixing. It is a slender structure to facilitate mixing with the agitator shaft. This type of container makes the raw material susceptible to end effects and disturbed settlement in the subsequent sedimentation process, reducing the problem of sedimentation efficiency.
