[0002] Ultrafiltration membrane refers to an artificial permeable membrane used in the ultrafiltration process. It is generally made of polymer materials such as cellulose acetate, cellulose acetate esters, polyethylene, polysulfone and polyamide. It is generally pre-made into various types of membrane components such as tubular, plate, roll, capillary, etc., and then multiple components are assembled together for use to increase the filtration area and facilitate maintenance. Ultrafiltration membrane is a polymer semi-permeable membrane used in the ultrafiltration process that can separate polymer colloids or suspended particles of a certain size from the solution.

[0003] Ultrafiltration membranes can intercept most of the suspended matter and colloids in water, so they are often used in the field of water purification. Existing ultrafiltration membrane water purification devices include an ultrafiltration membrane body and a water purification tank. The ultrafiltration membrane body is installed in the water purification tank, and then the water source to be purified is introduced into the water inlet tank through the water inlet pipe of the water purification tank, and then purified by the ultrafiltration membrane body. After purification, it is discharged through the drain pipe, and the water purification operation is completed;

[0004] However, since the size of the clean water tank is fixed, when installing the ultrafiltration membrane body, the operator needs to enter the clean water tank to fix it and connect it with the water inlet pipe and the drain pipe. The operation is inconvenient and the installation efficiency is low. Therefore, an ultrafiltration membrane water purification device that is easy to install is needed. Utility Model Content

[0007] As an improvement, a first threaded piece is fixedly provided on the top of the connecting sleeve, and a second threaded piece matched with the first threaded piece is connected to the bottom of the telescopic hose, so as to facilitate the connection between the connecting sleeve and the telescopic hose when installing the ultrafiltration membrane body.

[0008] As an improvement, a limiting groove for clamping the top of the ultrafiltration membrane body is provided in the connecting sleeve, and the limiting groove supports and limits the ultrafiltration membrane body.

[0009] As an improvement, the inner wall of the clamping ring is provided with a rubber sealing ring which is in close contact with the outer wall of the ultrafiltration membrane body, and the rubber sealing ring makes the installation of the ultrafiltration membrane body more secure.

[0010] As an improvement, the front outer wall of the water purification box is hingedly connected to provide a cover plate, and the opening and closing of the cover plate facilitates the installation and disassembly of the ultrafiltration membrane body.

[0011] As an improvement, the front end of the threaded rod extends to the outside of the water purification tank and is connected to a rotating handle. The setting of the rotating handle makes it convenient for operators to rotate the threaded rod.

[0012] The advantages of the utility model compared with the prior art are that the movable block can be moved out of the water purification tank by rotating the threaded rod, and then the ultrafiltration membrane body on the fixed water pipe at the top of the movable block can be installed and disassembled, and the arrangement of the telescopic hose on the water inlet pipe and the fixed hose on the drain pipe can facilitate the installation operation of the ultrafiltration membrane body, thereby greatly improving the installation and disassembly efficiency.
