Description

Technical Field

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

[0002] The flat ceramic membrane is a kind of ceramic membrane, which is an asymmetric membrane prepared from inorganic ceramic materials through special processes. The surface of the flat ceramic membrane is densely covered with micropores. According to the fact that within a certain membrane pore size range, the permeability is different for substances with different molecular diameters. With the pressure difference on both sides of the membrane as the driving force and the membrane as the filtering medium, when the feed liquid flows through the membrane surface under a certain pressure, only water, inorganic salts, and small molecule substances are allowed to pass through the membrane, while macromolecule substances such as suspended solids, colloids, and microorganisms in water are blocked. The existing patent with the publication number CN113181777A discloses a flat ceramic membrane filtering device. A scraper for scraping off attachments is movably arranged between the flat ceramic membranes, and a driving component for driving the scraper to move is arranged in the power chamber. The invention can effectively clean the attachments on the surface of the flat ceramic membrane, has a simple structure and is easy to operate. Although this device can clean the flat ceramic membrane, it is not convenient to disassemble and assemble the flat ceramic membrane, which greatly reduces the convenience of maintaining and replacing the flat ceramic membrane and brings certain adverse effects to actual use.
