Description

Membrane filtration concentration device Technical Field The utility model relates to the technical field of membrane filtration, in particular to a membrane filtration concentration device. Background The membrane filtration concentration device is a device for filtering and concentrating liquid by utilizing a membrane separation technology, the membrane filtration technology is to utilize a high-precision mask material with a selective separation function, the separation and concentration of different components in feed liquid are realized by precisely matching a filter element and a material system according to a mechanical screening principle, when the device is operated, the material is pressurized by a circulating pump, the feed liquid flows along the surface of a filter membrane at a certain flow rate, material molecules with a molecular weight larger than a membrane interception molecular weight do not permeate the membrane and flow back to a circulating groove, and the material or molecules with a molecular weight smaller than the membrane interception molecular weight permeate the membrane to form filtrate. The patent document with the publication number of CN218188953U discloses a membrane filtration concentration device, and relates to the technical field of membrane filtration concentration, the on-line screen storage device comprises a base, the support is installed to one side at base top, the filter vat is installed at the top of support, the internally mounted of filter vat has filtration membrane, the motor is installed at the center at filter vat top, the output of motor is connected with the pivot, the one end of pivot penetrates inside the filter vat, just the pivot is located filtration membrane's center, the bottom and the filtration membrane rotation of pivot are connected, the pivot is located the equal cover in surface at filtration membrane inside part both ends and is equipped with the link, two be connected with two drainage plates jointly between the link, and two the drainage plates are located the both ends of link respectively.
