Liquid extracting device for purifying biological enzyme

Abstract

The invention discloses a liquid extracting device for purifying biological enzyme. The liquid extracting device comprises a liquid extracting pipe, wherein a threaded through hole is formed in one end of the liquid extracting pipe; a threaded rod is in threaded connection with the liquid extracting pipe at the threaded through hole; a polygonal groove is formed in one end of the threaded rod; a spring is fixedly arranged on the inner wall of one side of the polygonal groove in the threaded rod; a metal disc is welded at one end of the spring; a brake lever is welded on one side of the metal disc; the section of the brake lever is polygonal; a rotating plate is welded at one end of the brake lever; sliding rails are arranged on two sides of the brake lever; one side of each sliding rail isfixedly connected with the side wall of the rotating plate and the other side of the sliding rail is in sliding connection with a sliding rail seat; a rotating handle is welded on one side, away fromthe threaded rod, of the rotating plate; and a rotational connecting seat is welded at one end of each sliding rail seat. Compared with an existing device, the liquid extracting device disclosed by the invention has the advantages that impurities can be isolated when liquid of the purified biological enzyme is well extracted; and the process of extracting liquid has controllability, and experiment personnel conveniently operates, so that misoperation is prevented.

Description

technical field [0001] The invention relates to the technical field of liquid pumping devices, in particular to a liquid pumping device for biological enzyme purification. Background technique [0002] Biological enzymes are organic substances with catalytic function produced by living cells, most of which are proteins, and a very small part is RNA. It is mainly used for desizing of cotton fabrics and degumming of silk. It has been widely used in various fields of textile dyeing and finishing, which reflects the superiority of biological enzymes in the dyeing and finishing industry. Enzymes were also obtained in the field of human skin care in 2016. It has entered the stage of clinical application. In order to better make biological enzymes contribute to the progress of human science, people need to purify biological enzymes. During the purification process, some tissue fluids need to be continuously extracted. and testing, and the existing device generally extracts the imp...

Problems solved by technology

[0002] Biological enzymes are catalytic organic substances produced by living cells. Most of them are proteins, and a small part is RNA. The manufacturing and application fields of biological enzymes are gradually expanding. It is mainly used for the desizing of cotton fabrics and the degumming of silk. It has been widely used in various fields of textile dyeing and finishing, which reflects the superiority of biological enzymes in the dyeing and finishing industry. Enzymes were also obtained in the field of human skin care in 2016. It has made an important breakthrough and has entered the stage of clinical application. In order to better make biological enzymes contribute to the progress of human science, people need to purify biological enzymes. During the purification process, some tissue fluids need to be continuously extracted. and testing, and the existing devices generally allow the impurities to be extracted together, which affects the process of the experiment. Therefore, we propose a pumping device for biological enzyme purification
