[0002] An industrial pure water machine is composed of three major parts: a pretreatment system, a fine treatment system, and a post-treatment system. After the raw water passes through a pretreatment system such as a PP filter element (sand rod filter), an activated carbon unit, and a water softener unit, the contents of suspended solids (particulate matter), colloids, organic matter, hardness, microorganisms, and other impurities in the water are greatly reduced, so as to reduce the treatment load of the fine treatment systems such as electro-deionization and extend their service life. Industrial pure water machines are mostly used for industrial pure water production, and the reverse osmosis membrane is an important component of industrial pure water machines.

[0003] The existing reverse osmosis membrane is a specific semi-permeable membrane, the purpose of which is to separate substances and water, so as to achieve the effect of filtration and purification. Over time, the reverse osmosis membrane will adsorb a large amount of substances, and these substances will block the reverse osmosis membrane, thus reducing the filtration and purification effect. The structure of the reverse osmosis membrane filtration device is complex, and it is inconvenient to install and disassemble the reverse osmosis membrane, and the use effect is poor.

One end of each of the two threaded rods 11 is movably connected to the U-shaped plate 1 through a bearing, and the two threaded rods 11 are respectively threadedly connected to two of the moving plates 8.

[0024] In some embodiments, as shown in the attached Figure 3 figure, a third sealing ring 14 is sleeved on the outer peripheral surfaces of the three water outlet pipes 5 and the three water inlet pipes 10 to improve the sealing performance between the water outlet pipes 5 and the second filter cylinder 4, and between the first filter cylinder 2 and the water inlet pipes 10. The three water outlet pipes 5 are all threadedly connected to the second filter cylinder 4, and the three water inlet pipes 10 are all threadedly connected to the first filter cylinder 2. As shown in the attached Figures 2-3 figure, connecting plates 12 are provided at the tops and bottoms of the two side rings 6. The four connecting plates 12 are respectively connected to the two side rings 6. On one side of each of the four connecting plates 12, there is a bolt. By rotating the bolt, the bolt moves out of the moving plate 8, thereby releasing the fixation between the connecting plate 12 and the moving plate 8, facilitating the installation and disassembly of the first filter cylinder 2 and the second filter cylinder 4. The four connecting plates 12 and the four moving plates 8 are respectively connected through four bolts. As shown in the attached Figures 1-2 figure, sliding rods 9 are provided at the bottoms of the first filter cylinder 2 and the second filter cylinder 4.

The threaded pipe is threadedly connected to the second filter cartridge 4.

[0027] The working principle of the present invention: The staff rotates the left threaded rod 11. Since the threaded rod 11 is movably connected to the U-shaped plate 1 through a bearing, the moving plate 8 is threadedly connected to the threaded rod 11, and the side ring 6 and the connecting plate 12 cooperate to limit the rotation of the moving plate 8. Therefore, the threaded rod 11 drives the moving plate 8 to move horizontally, thereby driving the connecting plate 12 to move horizontally, and further driving the side ring 6 to move horizontally. Since the side ring 6 is connected to the second filter cartridge 4, the side ring 6 drives the second filter cartridge 4 to move horizontally. Similarly, rotate the right threaded rod 11, so that the first filter cartridge 2 moves horizontally. After the first filter cartridge 2 and the second filter cartridge 4 move away from each other, remove the buckle to release the fixation between the reverse osmosis membrane 15 and the second filter cartridge 4, and take out the reverse osmosis membrane 15 from the second filter cartridge 4. The operation is simple, which is convenient for the installation and disassembly of the reverse osmosis membrane 15, convenient for replacing the reverse osmosis membrane 15, and has good use effect. By setting a plurality of third sealing rings 14, the sealing performance between the water outlet pipe 5 and the second filter cartridge 4, and between the first filter cartridge 2 and the water inlet pipe 10 is improved. By setting the first sealing ring 3, the sealing performance between the first filter cartridge 2 and the second filter cartridge 4 is improved. By setting the bolts, rotate the bolts so that the bolts move out of the moving plate 8, thereby releasing the fixation between the connecting plate 12 and the moving plate 8, which is convenient for the installation and disassembly of the first filter cartridge 2 and the second filter cartridge 4. At the same time, the side ring 6 drives the bottom moving plate 8 to move on the sliding rod 9, improving the stability of the side ring 6. By setting the limit blocks 16, the reverse osmosis membrane 15 is in contact with the limit blocks 16, and the limit blocks 16 limit and support the reverse osmosis membrane 15;

[0028] By setting the storage box 7, the storage box 7 collects the substances blocked on the reverse osmosis membrane 15. Rotate the threaded pipe so that the threaded pipe moves out of the second filter cartridge 4, thereby releasing the fixation between the second filter cartridge 4 and the storage box 7. Insert the brush into the second filter cartridge 4 through the feed inlet, and clean the substances adhered to the reverse osmosis membrane 15 with the brush. The operation is simple, which is convenient for cleaning the substances adhered to the reverse osmosis membrane 15, and the service life of the reverse osmosis membrane 15 is long. By setting the second sealing ring 13, the sealing performance between the second filter cartridge 4 and the threaded pipe is improved.

[0029] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
