Description

Technical Field

[0001] The utility model relates to the technical field of medicine separation, in particular to a filtering device for biological medicine separation. Background Art

[0002] Biopharmaceutical raw materials are mainly natural biological materials, including microorganisms, human bodies, animals, plants, marine organisms, etc. In the field of biopharmaceuticals, it is often necessary to mix different types of APIs together, and after a series of reactions, filter and separate the fixed impurities in the liquid.

[0003] The existing biomedical separation filtration device only simply filters the drug solution through the filter during use, so that the drug solution is not filtered thoroughly. At the same time, the drug solution residue is easily accumulated on the filter, which is inconvenient to clean and easily causes the filter to be blocked. Therefore, we introduce a new filtration device for biomedical separation. Utility Model Content

[0013] 1. Add different types of APIs into the mixing tank from the drug inlet pipe, start the motor, the motor drives the rotating rod to rotate, and the rotating rod drives the spiral stirring blade to rotate to mix the liquid medicine in the mixing tank. During the mixing process, two cleaning rollers move in a circle along the inner wall of the mixing tank to clean the inner wall, so as to avoid a lot of liquid medicine remaining on the inner wall of the mixing tank and avoid wasting the liquid medicine;

[0014] 2. The mixed medicine liquid enters the filter box through the lower liquid pipe, and the solid impurities in the medicine liquid are filtered through the filter plate in the filter box. The filtered medicine liquid enters the bottom of the filter box. By starting the circulation pump, the circulation pump returns the medicine liquid at the bottom of the filter box to the mixing tank through the circulation pipe for secondary stirring, and then enters the filter box for secondary filtration, which can improve the filtration efficiency. The fixed impurities on the filter plate are removed by starting two cylinders. The two cylinders push the scraper to the left, so that the solid impurities on the filter plate are pushed to the left side of the filter plate, and then they are cleaned by opening the cleaning port, which can avoid clogging of the filter plate and affecting the filtration effect.
