Description

Technical Field

[0001] The utility model relates to the technical field of purification and filtration, in particular to a novel biochemical filter membrane hierarchical purification and filtration device. Background Art

[0002] Biochemical filter membrane is a membrane material used to separate and purify biological molecules or cells. It is usually made of polymers or other materials, has a specific pore size and chemical properties, and can selectively filter substances according to their size, shape or chemical properties. It is often used in protein purification, cell separation, wastewater treatment and drug production.

[0003] When using existing biochemical filter membranes, multi-layer pipelines are used to purify and filter solutions, and different substances are filtered through different layers of biochemical filter membranes to improve the filtering and purification effect. However, since the filtration is performed by the internal solution pressure, the substances filtered out internally will be adsorbed on the filter membrane after a period of use, which will lead to a decrease in the filtration permeability over a long period of time, resulting in a low efficiency of the purification and filtration process of the device, and a high labor intensity for frequent cleaning. At the same time, when cleaning the internal filtered substances, the purification and filtration needs to be stopped, and the overall purification and filtration production output is reduced during the stop period. Utility Model Content

[0006] By adopting the above technical scheme, the filter membrane frame and the cleaning frame are installed in sequence by using a threaded connection method, and the solution is filtered and purified using a biochemical membrane. During the filtration period, the motor drives the cleaning frame to rotate to clean the inner wall of the biochemical membrane at a uniform speed, so that the substances adsorbed on the biochemical membrane during the filtration process can be stirred to improve the filtration permeability of the biochemical membrane, reduce the number of times the internal filtered substances are cleaned, thereby improving the overall filtration and purification efficiency and reducing the labor intensity of workers in cleaning.

[0013] Preferably, the threaded rotating shaft at the bottom of the second filter tank and the threaded rotating shaft at the bottom of the first filter tank are drivingly connected with a tape ruler.

[0014] By adopting the above technical solution, the motor at the bottom of the first filter tank can be used to drive the threaded shaft at the bottom of the second filter tank using a ruler, so that the cleaning frame can continue to rotate back and forth for cleaning during filtration to ensure the permeability of the biochemical membrane and achieve the effect of efficient purification filtration.
