Description

Technical Field

[0001] This utility model belongs to the field of reverse osmosis membrane cleaning technology, and specifically relates to a reverse osmosis membrane cleaning device. Background Technology

[0002] A reverse osmosis membrane is a semi-permeable membrane that can effectively separate solutes and solvents in a liquid. Its working principle is based on the reverse osmosis process, which removes solutes by applying pressure to force the solvent (usually water) to flow from the high concentration solution side to the low concentration solution side. Reverse osmosis membranes have extremely small pore sizes, allowing only water molecules to pass through while blocking most larger molecules such as dissolved salts, bacteria, and organic matter.

[0003] In the water treatment industry, reverse osmosis membranes are one of the important separation technologies, widely used in water purification and seawater desalination. However, traditional reverse osmosis membrane cleaning methods, especially hot water cleaning, have some significant drawbacks. First, hot water cleaning usually requires manual handling of the reverse osmosis membrane. This method is not only labor-intensive but also requires workers to maintain physical labor for extended periods, easily leading to fatigue and improper operation. Furthermore, the manual handling of the membrane requires a high level of skill from the workers, increasing the complexity of the operation. Second, workers face the risk of burns during hot water cleaning. Due to the high temperature of the water used, workers are prone to burns from contact with the hot water while handling the reverse osmosis membrane. This safety hazard not only affects the health and safety of workers but may also lead to a decrease in production efficiency. Therefore, a reverse osmosis membrane cleaning device is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example

[0021] Depend on Figure 1-4 A reverse osmosis membrane cleaning device is provided, including a cleaning tank 1, the cleaning tank 1 having a cavity and a filter plate 11 assembled in the cavity;

[0022] A set of cleaning components 2 is installed at the upper end of the cleaning tank 1;

[0023] The cleaning assembly 2 includes a lead screw seat 20, which has a rectangular cavity and a drive motor 21 is installed inside the rectangular cavity. The output end of the drive motor 21 is connected to a threaded lead screw 22 via a coupling. A slider 23 is externally threaded to the threaded lead screw 22 and is located inside the rectangular cavity of the lead screw seat 20. A mounting plate 24 is mounted on one side of the slider 23. Two positioning plates 25 are mounted on the lower end face of the mounting plate 24 and are arranged in parallel. A soft roller 26 is rotatably connected between the two positioning plates 25 via a rotating shaft and is located inside the cavity of the cleaning tank 1.

[0024] In this embodiment, through the cooperation between the components within the cleaning assembly 2, the drive motor 21 can drive the soft roller 26 to reciprocate within the stroke range of the threaded screw 22 to clean the reverse osmosis membrane. This reduces the need for manual handling and operation, eliminating the need for workers to hold the reverse osmosis membrane for extended periods, thus reducing physical labor and fatigue. The device accelerates the cleaning process, improves overall production efficiency, and shortens the cleaning time of the reverse osmosis membrane. Simultaneously, the water circulation system, combined with the cleaning assembly 2, enables continuous cleaning, reducing downtime. Workers do not need to directly contact high-temperature water, significantly reducing scalding and other safety hazards caused by hot water operation. The soft roller 26 can apply force evenly, thoroughly removing dirt and contaminants from the surface of the reverse osmosis membrane while avoiding scratching or damaging the membrane. The pressure plate 14 limits the two ends of the reverse osmosis membrane, ensuring its stability during cleaning, preventing displacement or damage, and improving the consistency and effectiveness of the cleaning process.

[0025] Specifically, refer to Figure 1-2 A connecting pipe 3 is connected to the lower end of one side of the cleaning pool 1. A water tank 31 is installed on one side of the cleaning pool 1 and one end of the connecting pipe 3 is connected to the bottom of the water tank 31. A water pump 32 is installed on the upper surface of the water tank 31. A delivery pipe 33 is connected to the output end of the water pump 32 and one end of the delivery pipe 33 is located above the cleaning pool 1.

[0026] In this embodiment, the connecting pipe 3, together with the water tank 31, the water pump 32 and the delivery pipe 33, can extract the hot water in the cleaning pool 1 for water circulation, thereby saving water resources.

[0027] Specifically, refer to Figure 1-2 The cleaning pool 1 has two sliding grooves 12 on each side. Threaded rods 13 are slidably installed in each of the four sliding grooves 12. A pressure plate 14 is installed between two adjacent threaded rods 13 on the same side, and a deep groove ball bearing is installed at the connection with the pressure plate 14. Rotary covers 15 are threadedly connected to the outside of the four threaded rods 13, and one side of the rotary cover 15 is tightly abutted against one side of the cleaning pool 1.

[0028] In this embodiment, the four rotating covers 15 are rotated to release the tight contact between the rotating covers 15 and the cleaning tank 1. Then, the positions of the two pressure plates 14 are adjusted to limit the two ends of the reverse osmosis membrane. The rotating covers 15 are rotated in the opposite direction to fix the position of the pressure plates 14.

[0029] Specifically, refer to Figure 3-4 Two fixing plates 27 are installed on one side of the upper end of the cleaning pool 1. A sliding rod 28 is installed between the two fixing plates 27. A connecting block 29 is slidably provided on the outside of the sliding rod 28, and one side of the connecting block 29 is connected to one end of the mounting plate 24.

[0030] In this embodiment, the sliding rod 28, together with the connecting block 29, is used to limit the movement of the soft roller 26, so that the soft roller 26 can be moved more stably.

[0031] Specifically, refer to Figure 3-4 The drive motor 21 is equipped with four limit rods 211 on one side, and all four limit rods 211 pass through the slider 23.

[0032] In this embodiment, the four limiting rods 211 are used to limit the slider 23, so that the slider 23 can be moved more stably, thereby improving the overall stability of the device.

[0033] The reverse osmosis membrane cleaning device of this utility model:

[0034] In actual use, the reverse osmosis membrane is passed through two pressure plates 14 and positioned below the soft roller 26. The four rotating covers 15 are rotated to release their tight contact with the cleaning tank 1. Then, the positions of the two pressure plates 14 are adjusted to limit the ends of the reverse osmosis membrane. Rotating the rotating covers 15 in the opposite direction fixes the position of the pressure plates 14. Hot water is then injected into the cleaning tank 1 until it covers the reverse osmosis membrane. The drive motor 21 is then activated, causing it to rotate the threaded screw 22. When the lead screw 22 rotates, the slider 23 connected to the external thread of the lead screw 22 drives the soft roller 26 on one side to reciprocate within the stroke range of the lead screw 22, thereby cleaning the reverse osmosis membrane. The filter plate 11 can filter the impurities from the cleaning. The connecting pipe 3, together with the water tank 31, water pump 32 and delivery pipe 33, can extract the hot water in the cleaning tank 1 for water circulation. After cleaning one side of the reverse osmosis membrane, the reverse osmosis membrane can be pulled out and flipped over by adjusting the two pressure plates 14. Repeating the above operation can clean the other side of the reverse osmosis membrane.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
