Filtering device used for biological pharmacy

Abstract

The invention discloses a filtering device used for biological pharmacy. The filtering device comprises a box body, wherein the inner walls of two opposite sides of the box body are fixedly provided with symmetrical connecting blocks; a filtering mechanism is fixedly arranged at the top parts of the connecting blocks; a discharging pipe is fixedly arranged on the filtering mechanism; a position ofthe center of the inner wall of the top part of the box body is rotatably inserted with a rotating shaft; a plurality of annularly-distributed scraping plates are fixedly arranged at the bottom end of the rotating shaft; the bottom ends of the scraping plates are attached to the filtering mechanism; a fixed ring is fixedly arranged at the top end of the rotating shaft; annularly-distributed driving plates are fixedly arranged on the smooth outer wall of the fixed ring; and a material conveying mechanism is fixedly arranged on the outer wall of one side of the box body. According to the invention, the driving plates and the scraping plates located at the bottom end of the rotating shaft are driven by the push force of a water flow to rotate synchronously, and the scraping plates scrape impurities adhering to the upper surface of a filter screen in the process of rotating and push the impurities into the discharging pipe in a centralized manner for discharging, so surface cleanliness ofthe filter screen is improved, and smoothness of filtering work is improved.

Description

technical field [0001] The invention relates to the technical field of filtration, in particular to a filtration device for biopharmaceuticals. Background technique [0002] Biopharmaceuticals refer to the comprehensive utilization of microbiology, chemistry, biochemistry, biotechnology, pharmacy and other scientific research results from organisms, biological tissues, cells, organs, body fluids, etc. It is a kind of product used for prevention, treatment and diagnosis manufactured by the principle and method. In the pharmaceutical process, the medicine and other media will be separated through some filtering equipment to make the medicine more pure. [0003] In the existing technology, it is necessary to filter the liquid raw materials in the work of biopharmaceuticals to improve the purity of the raw materials. There are some shortcomings in the existing filtering work. The completeness of the work needs to be cleaned up in a timely manner. Contents of the invention ...

Problems solved by technology

[0003] In the prior art, it is necessary to filter liquid raw materials in biopharmaceutical work to improve the purity of raw materials. There are some shortcomings in the existing filtering work. For example, a layer of impurities will adhere to the surface of the filter after a long time of filtering work, which will affect the filtration. The completeness of the work needs to be cleaned up in a timely manner
