Multi-layer filtering device used for separation and purification of biological pharmacy

Abstract

The invention provides a multi-layer filtering device used for separation and purification of biological pharmacy, wherein the multi-layer filtering device can make better use of biological raw materials. The multi-layer filtering device comprises a casing (1), an installation table (6) is arranged on the casing (1) and is equipped with a material inlet pipe (2) downwards inserted into the casing (1), and the material inlet pipe (2) is connected with a first-level filtering film (3), a second-level filtering film (4) and a third-level filtering film (5) from inside to outside sequentially; each of the three filtering films is provided with a spherical structure formed by assembling two hemi-spherical structures, filtration apertures of the three filtering films are gradually reduced from inside to outside, and the material inlet pipe (2) directly penetrates into the first-level filtering film (3) with a smallest diameter; a sealing connector (10) is arranged on the connection portion of the material inlet pipe (2) and each filtering film; a liquid outlet pipe (7) is further arranged at the bottom of the casing (1) and is further provided with a flow control valve (8); an electric control tap valve (13) is arranged at the bottom of each filtering film.

Description

technical field [0001] The invention relates to a production equipment for biopharmaceuticals, in particular to a multi-layer filter device for separation and purification of biopharmaceuticals. Background technique [0002] Biopharmaceutical raw materials are mainly natural biological materials, including microorganisms, human bodies, animals, plants, marine organisms, etc. With the development of biotechnology, purposefully artificially prepared biological raw materials have become the main source of current biopharmaceutical raw materials. Such as animal raw materials obtained by immunization, microorganisms or other cell materials obtained by changing the genetic structure, etc. Biopharmaceuticals are characterized by high pharmacological activity, low toxicity and side effects, and high nutritional value. Biopharmaceuticals mainly include proteins, nucleic acids, carbohydrates, lipids, etc. The constituent units of these substances are amino acids, nucleotides, monos...

Problems solved by technology

This structure has a disadvantage, which is the low utilization rate of raw materials. In the prior art, most of the biological raw materials are a mixture of proteins, nucleic acids, sugars, lipids and other substances. If the protein is directly filtered out, other mixed Raw materials are wasted
