Description

Technical Field

[0001] The utility model relates to the technical field of membrane filtering devices, in particular to a membrane filtering device. Background Art

[0002] Membrane filtration is a screening process related to the size of membrane pores. It uses the pressure difference on both sides of the membrane as the driving force and the membrane as the filtration medium. Under a certain pressure, when the raw liquid flows through the membrane surface, the many tiny micropores densely distributed on the membrane surface only allow water and small molecules to pass through and become permeate, while substances in the raw liquid with a volume larger than the micropore size of the membrane surface are retained on the liquid inlet side of the membrane and become concentrated liquid, thereby achieving the purpose of separation and concentration of the raw liquid.

[0003] The Chinese utility model currently published with the publication number CN211871971U discloses a protein element biofilm filtration and extraction device, including a shell, a stirring structure, a rocker, a connecting rod, a slider, a rotating shaft, a rotating plate, a base, a slide groove, a biofilm filtration layer and an installation drawer. The beneficial effects of the utility model are: after the protein element aqueous solution is initially filtered, the rocker is rotated, the rocker and the shell are rotatably connected, the rocker drives the connecting rod to rotate, the connecting rod drives the rotating shaft, and the rotating shaft drives the slider to slide in the slide groove. Since the slide groove is elliptical and the length of the connecting rod is constant, the rotating shaft revolves under the action of the connecting rod while the rotating shaft also rotates, thereby driving the rotating plate on the rotating shaft to rotate, greatly increasing the stirring effect, and increasing the solubility of the protein element in the aqueous solution. When used in conjunction with the biofilm filtration layer at the lower end of the shell, a large amount of protein element is avoided from being lost with the aqueous solution due to insufficient stirring, thereby effectively avoiding a large amount of protein element waste, thereby increasing the yield of protein element.

[0004] When the existing membrane filtration device is filtering a solution, the filter membrane is usually in a static state, and the solution can only fall under the action of its own gravity, which reduces the filtration efficiency of the filter membrane. In addition, most of the existing filter membranes are fixed, which makes it inconvenient to disassemble and replace the filter membrane. After the filter membrane is used for a long time, impurities are easily accumulated on its surface, thereby reducing the filtration effect of the solution. Utility Model Content
