Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a water tank filter membrane installation frame, and in particular to a curtain-type membrane installation frame for a purified water tank. Background Art

[0002] The commonly used filter membrane for purified water tanks is curtain membrane, which is a membrane separation technology, also known as AC filtration. During the filtration process of the curtain membrane, the solution flows parallel to the membrane surface at a certain speed instead of passing through the membrane vertically. This parallel flow can reduce the blockage and pollution of the membrane surface, thereby improving the service life and efficiency of the membrane. The curtain membrane is usually composed of a number of porous hollow fiber membrane filaments and a pair of water collecting pipes. The curtain membrane is generally used in conjunction with an aeration tube. The size of the holes on the curtain membrane can be selected as needed to achieve the separation effect of substances of different particle sizes. Air is input through the aeration tube to apply a certain pressure to the purified water tank, so that the target molecules or particles in the solution can pass through the micropores of the membrane, while larger molecules or impurities are blocked on the membrane surface, thereby realizing the water treatment process.

[0003] At present, when installing curtain membranes, the water collecting pipe is usually welded directly to the installation structure, and then the aeration pipe is welded to the installation structure under the curtain membrane, and then the curtain membrane and the installation frame are placed in the purified water tank. This installation method leads to the problem of inconvenient installation and disassembly process during the later maintenance of the curtain membrane. At the same time, the curtain membrane can only be replaced by forcibly dismantling the curtain membrane, which is easy to damage the hollow fiber membrane and cause unnecessary losses.
