Description

Technical Field

[0001] The utility model relates to the technical field of hydrophilic filtering devices, in particular to an ultrafiltration membrane wire hydrophilic treatment device. Background Art

[0002] Ultrafiltration membrane filament is a component that plays a key role in the ultrafiltration process. It is mainly used for fine filtration and separation of liquids. Ultrafiltration membrane filament is made of polymer materials and has membrane elements with micro-nano pore sizes. They usually exist in the form of hollow fibers and have a large specific surface area and high-efficiency filtration performance. During the ultrafiltration process, water or other liquids pass through the micropores of the ultrafiltration membrane filament under the action of pressure difference, while impurities such as suspended matter, colloids, and microorganisms in the solution are retained on one side of the membrane, thereby achieving the purpose of purifying the liquid.

[0003] After a period of use, the existing ultrafiltration membrane fibers accumulate excessive internal impurities, resulting in reduced hydrophilicity or loss of function. Based on these problems, Chinese patent CN208893984U discloses an ultrafiltration membrane fiber hydrophilic device, which can effectively filter impurities in the filtrate through the filtration holes on the ultrafiltration membrane. The ultrafiltration membrane adopts hollow membrane fibers to increase the filtration contact area, and has higher hydrophilicity than traditional hydrophilic membranes, and has fast filtration speed, long service life, strong anti-fouling ability, safety and stability, and a wide range of applications. Water enters through one end of the membrane hole and sewage is discharged at the other end, effectively preventing the filtration holes from being blocked, so that the hydrophilic membrane always remains hydrophilic, which is convenient for filtration of the hydrophilic device. The structural design is simple and reasonable, easy to operate, and easy to disassemble and adjust, so as to solve the problem of internal impurities accumulating and causing reduced hydrophilicity or loss of function.

[0004] The membrane filaments in the device are directly installed on the first fixed plate and the second fixed plate. Therefore, when impurities accumulate on the membrane filaments, the staff must disassemble, process or replace the membrane filaments. However, there are so many membrane filaments that the staff cannot know which group of membrane filaments has accumulated more impurities. Therefore, it will bring a lot of inconvenience to the staff in disassembling the membrane filaments. Direct disassembly of the filter element will also hinder the normal progress of the hydrophilic treatment. Utility Model Content

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] (1) When the cylinder is turned on, the push plate on the slide can be pushed upward, and the sealing ring will also move upward to seal the liquid permeable holes. A set of push plates can only seal the liquid permeable holes on a part of the ultrafiltration membrane filament treatment tubes. Therefore, the ultrafiltration membrane filament treatment tubes with unblocked liquid permeable holes can still be hydrophilic treated. When the shaft disc rotates with the shaft core at the bottom of the column, the first sealing disc will rotate along with it, and the membrane filament body will be tightened, thereby squeezing out the impurities attached to the membrane filament body. When the first sealing disc moves downward, it will squeeze the membrane filament body, thereby squeezing out the impurities attached to the membrane filament body. Then the impurities and sewage will be discharged directly from the sewage pipe, which not only saves the time of the staff in disassembling the membrane filament or filter element, but also allows the hydrophilic treatment work to proceed smoothly.

[0022] (2) Before removing impurities and sewage on the membrane fiber body in the ultrafiltration membrane fiber treatment tube, it is necessary not only to seal the permeable hole with a sealing ring, but also to rotate the turntable to move the water inlet hole away from the top of the membrane fiber body. Only then can the first sealing disk be rotated or moved downward. When the turntable is rotated, when the water inlet hole moves to the top of the membrane fiber body, the water in the junction box will pass through the water inlet hole into the membrane fiber body. When the water inlet hole is removed from the top of the membrane fiber body, the water in the junction box will not be able to enter the membrane fiber body.

[0023] (3) By setting a connection structure between the plug shaft, the support ring and the threaded cover, the ultrafiltration membrane filament processing tube can be fixed in the processing box. By setting a simple connection method between the plug shaft, the support ring and the threaded cover, the disassembly and assembly steps of the ultrafiltration membrane filament processing tube are made more convenient and quick.
