[0026] Example: Please refer to Figure 1-5 A supportless reverse osmosis membrane tank installation structure includes a treatment tank 1, a drain pipe 2 fixedly connected to the bottom right side of the treatment tank 1, a raw water inlet pipe 13 fixedly connected to the bottom left side of the treatment tank 1, a tank cover 14 fixedly connected to the top of the treatment tank 1, multiple sets of plastic outer shells 10 are arranged inside the treatment tank 1, a water collection pipe 12 is vertically inserted inside the plastic outer shell 10, multiple sets of reverse osmosis membrane modules 11 are covered on the outside of the water collection pipe 12, and a supportless membrane module installation assembly is arranged at the bottom of the inside of the treatment tank 1.

[0027] Please see Figure 1-5 A reverse osmosis membrane tank installation structure without support also includes a membrane module installation assembly. The membrane module installation assembly includes a partition plate 3, which is horizontally fixed between the two sides inside the treatment tank 1.

A first sealing ring 6 is glued to the top of the internal threaded interface 5. Multiple sets of upper slots 7 are opened at the top of the water tank cover 14. A second sealing ring 8 is glued to the inner wall of the upper slot 7. A first solenoid valve 9 is installed on the left side of the purified water discharge pipe 4.

[0028] The front and rear ends of the isolation plate 3 are connected to the front and rear ends of the inside of the treatment tank 1. The left side of the clean water discharge pipe 4 passes through the treatment tank 1 and extends to the outside. The upper and lower ends of the outside of the water collection pipe 12 are threaded respectively. The threads on the outside of the water collection pipe 12 match the threads inside the internal thread interface 5. The outer diameter of the water collection pipe 12 is compatible with the inner diameter of the second sealing ring 8. The second sealing ring 8 is elastic, does not require a bracket, and is convenient for disassembling and assembling the membrane assembly.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the internal threaded interface 5 and the upper slot 7 respectively restrict the vertical position of the water collection pipe 12, keeping it upright. The first sealing ring 6 presses against the bottom of the plastic outer shell 10 to increase the seal, and the second sealing ring 8 holds the water collection pipe 12 tightly to ensure a tight seal. For later disassembly, first remove the water tank cover 14, then directly rotate the plastic outer shell 10 to remove it from the internal threaded interface 5 for replacement. The installation takes up little space and is simple to assemble and disassemble.

[0030] Two sets of flushing water inlet pipes 15 are provided above the water tank cover 14. Multiple sets of movable joints 16 are provided at the bottom of the flushing water inlet pipes 15. A second solenoid valve 17 is installed on the right side of the flushing water inlet pipes 15. The water collection pipe 12 and the movable joints 16 are threaded together. The water collection pipe 12, the flushing water inlet pipe 15, and the movable joints 16 are internally connected to facilitate backwashing to clean internal blockages.

[0031] Specifically, such as Figure 1 As shown, the second solenoid valve 17 is open and the first solenoid valve 9 is closed. The water pump pumps external pure water into the water collection pipe 12 through the flushing inlet pipe 15 and the movable joint 16. The water pressure inside the water collection pipe 12 increases, and the water flows out in the reverse direction along the reverse osmosis membrane module 11, flushing out the blockage.

[0032] Electric cylinders 18 are installed on both sides of the top of the water tank cover 14. Push plates 19 are installed on both sides inside the treatment tank 1. Two sets of scrapers 20 are horizontally fixed between the two sets of push plates 19. Multiple sets of circular grooves 21 are opened inside the scrapers 20. Annular brushes 22 are fixedly connected to the inner wall of the circular grooves 21. The bristles of the annular brushes 22 are in contact with the surface of the plastic outer shell 10.

[0033] Specifically, such as Figure 1 and Figure 4 As shown, the electric cylinder 18 pushes the push plate 19 to move up and down reciprocally, and the scraper 20 moves up and down synchronously. The annular brush 22 inside the circular groove 21 brushes the outside of the plastic outer shell 10 to clean the surface of the adhering substances, and the sewage is discharged from the drain pipe 2.

[0034] Working Principle: In use, raw water first enters the treatment tank 1 through the raw water inlet pipe 13. The reverse osmosis membrane module 11 inside the plastic outer shell 10 intercepts excess substances in the water. The purified water is collected from the water collection pipe 12 and discharged outwards along the internal threaded interface 5 and the purified water discharge pipe 4. The internal threaded interface 5 and the upper slot 7 respectively restrict the vertical position of the water collection pipe 12, keeping it upright. The first sealing ring 6 presses against the bottom of the plastic outer shell 10 to increase the seal, and the second sealing ring 8 holds the outer packaging of the water collection pipe 12 tightly to ensure a seal. Later disassembly... During disassembly, first remove the water tank cover 14, then directly rotate the plastic outer shell 10 to remove it from the internal thread interface 5 for replacement. The installation occupies little space and is simple to install and disassemble. Regular backwashing of the membrane module is necessary to ensure its filtration capacity. The water pump is connected to the flushing inlet pipe 15. As the second solenoid valve 17 opens and the first solenoid valve 9 closes, the water pump pumps external purified water along the flushing inlet pipe 15 and the movable joint 16 into the water collection pipe 12. The water pressure inside the water collection pipe 12 increases, and the water flows backward along the reverse osmosis membrane module 11, flushing out blockages. Simultaneously with backwashing, the electric cylinder 18 pushes the push plate 19 up and down, and the scraper 20 moves up and down synchronously. The annular brush 22 inside the circular groove 21 brushes the exterior of the plastic outer shell 10, cleaning surface deposits. Wastewater is discharged from the drain pipe 2.
