Spiral extrusion supplying device for biological product materials

Abstract

The invention discloses a spiral extrusion supplying device for biological product materials. The spiral extrusion supplying device for the biological product materials comprises supporting posts, a burette, a top plate and a burette fixing plate. Antiskid blocks are installed at the bottom ends of the supporting posts, the top plate is welded to the top ends of the supporting posts, a threaded post is installed on the top plate in a penetrating mode, a rotary handle is welded to the top of the threaded post, a limiting block is arranged at the bottom end of the threaded post, and an insertinggroove is formed in the limiting block. A pushing rod is installed at the top end of a rubber plug, a limiting groove is formed in the top end face of the pushing rod, an inserting block is arrangedin the limiting groove, the threaded post and the pushing rod are fixed in an inserted mode through the inserting groove and the inserting block, a burette limiting block is welded to the top surfaceof the burette fixing plate, a titration port limiting hole is formed in the burette limiting block in a penetrating mode, the bottom end of the burette is provided with a titration port, and the burette and the burette fixing plate are installed in a limiting mode through the titration port and the titration port limiting hole. The spiral extrusion supplying device for the biological product materials has the advantage of being capable of controlling the dosage of titration supplying.

Description

technical field [0001] The invention relates to the technical field of biological product feeding, in particular to a screw extrusion feeding device for biological product materials. Background technique [0002] Biological products refer to the preparation of biological materials such as microorganisms, cells, tissues and liquids of various animal and human origins obtained by ordinary or genetic engineering, cell engineering, protein engineering, fermentation engineering, etc., and are used for the prevention of human diseases , therapeutic and diagnostic medicines. However, in the past, the feeding of biological products was titrated with a rubber dropper, and the titrated dose was not easy to control, so the expected experimental effect could not be achieved. Contents of the invention [0003] The object of the present invention is to provide a kind of screw extrusion feeding device for biological product materials, which has the advantage of being able to control the...
