Description

Technical Field

[0001] The utility model relates to the technical field of nanofiltration membrane filtration, in particular to a filtration device used for electric nanofiltration membrane experimental equipment. Background Art

[0002] Electrofiltration membrane is a type of nanofiltration membrane. Nanofiltration membrane is a functional semi-permeable membrane that allows solvent molecules or certain low molecular weight solutes or low-valent ions to pass through. Nanofiltration membrane can be used to remove organic matter and color from surface water, remove hardness from groundwater, partially remove soluble salts, concentrate fruit juice, and separate useful substances in medicines.

[0003] Chinese patent announcement CN218307247U discloses a high-temperature nanofiltration membrane filtering device, in which the filter housing is installed in the through hole of the support frame, and the bidirectional screw is rotated, so that the first sealing block moves in the installation cavity. During the movement of the second sealing block, one end thereof will pass through the circular hole on the filter housing, and then the limiting sleeve is rotated to make it threadedly connected with the second sealing block. During the movement of the moving block with the fixed sleeve, the extrusion rod will move up until the bonding plate and the surface of the filter housing are bonded, and finally the connecting pipe on the box body and the feed port on the filter housing are clamped to complete the installation of the filter housing and the nanofiltration membrane. Similarly, when the filter housing and the nanofiltration membrane inside it are damaged, it is convenient to disassemble and replace the filter housing and the nanofiltration membrane inside it, which is beneficial to the subsequent use of the high-temperature nanofiltration membrane filtering device.

[0004] When the above-mentioned filter device is installed, the fixing rod is moved to move the limiting sleeve, and the limiting sleeve is moved by rotating so that the limiting sleeve drives the second sealing block to move. During the movement of the second sealing block, one end of the limiting sleeve passes through the circular hole on the filter housing, and then the limiting sleeve is rotated to be threadedly connected with the second sealing block to complete the initial limiting fixation of the filter housing. The operation is cumbersome. Utility Model Content
