Abstract
Description
Technical Field
[0001] This invention relates to the field of RO membrane cleaning technology, specifically to a mobile cleaning device and method for reverse osmosis (RO) membranes. Background Technology
[0002] Reverse osmosis (RO) membranes are a common water treatment filtration material that allows water molecules and some mineral ions to pass through. When in use, under certain pressure, water molecules can pass through the RO membrane, while impurities such as inorganic salts, heavy metal ions, organic matter, colloids, bacteria, and viruses in the source water cannot pass through the RO membrane. This allows the permeable pure water and the non-permeable concentrated water to be strictly separated and discharged separately.
[0003] With the advancement of technology, reverse osmosis (RO) membranes are being used more and more widely, offering a good user experience in both residential and commercial applications. After prolonged use, a large amount of scale and debris accumulates between the wound membrane sheets of RO membranes. When small-flux RO membranes in residential applications become clogged or contaminated, they can be directly replaced with brand new products. However, commercial RO membranes require a larger quantity and are more expensive. To reduce costs, RO membranes are often acid-washed. However, acid washing typically involves pressurizing the acid solution and circulating it through the RO membrane to achieve the cleaning purpose. A single cleaning session often takes hours, making it time-consuming and inconvenient to use. Summary of the Invention

The cover is inserted into the upper end of the cleaning cylinder to seal the cleaning cavity.
[0019] A method for cleaning a reverse osmosis (RO) membrane, applied to the aforementioned reverse osmosis (RO) membrane cleaning equipment, includes the following steps:
[0020] Step 1: A drive motor is horizontally installed on one side of the support frame. The drive motor, in conjunction with the gear, controls the flipping shaft to perform flipping movement. When the opening of the cleaning tube is vertical, it is in the cleaning state. When the opening of the cleaning tube is tilted upward, it is in the state of placing the RO membrane roll. When the opening of the cleaning tube is tilted downward, it is in the state of automatically moving the RO membrane roll.
[0021] Step 2: After inserting the RO membrane roll into the cleaning chamber of the cleaning cylinder, the RO membrane roll is stably inserted under the surrounding and positioning effect of the contact strip, and is limited by the action of the support ring;
[0022] Step 3: Start the clamping telescopic rod by pulling down the clamping push rod and the prismatic synchronous rod. At this time, the synchronous seat drives the two clamping rods to descend simultaneously. Under the action of the retracting rod and the inclined surface of the abutment block, the two clamping rods retract towards the outlet of the RO membrane roll, completing the clamping and fixing of the RO membrane roll. The clamping force can be adjusted according to the pull-down degree of the clamping telescopic rod as needed.
[0023] Step 4: Connect the citric acid-based cleaning solution to the inlet tank side of the tilting shaft through the pressurized pipeline. When tilting is required, keep the cleaning cylinder vertical and seal the opening of the cleaning cylinder with the cap. The cleaning solution is introduced into the inlet tank and flows downward from the top of the cleaning chamber to clean the RO membrane roll.
[0024] Step 5: The motor drives the drive gear to rotate. At this time, under the transmission action of the drive gear, the control seat and the moving cylinder rotate in opposite directions. When the control seat rotates, under the action of the prismatic structure of the prismatic synchronizing rod, the synchronizing seat drives the RO membrane roll held by the clamping rod to rotate synchronously, and then the RO membrane roll and the moving cylinder rotate in opposite directions.
[0025] Step Six: When the RO membrane roll and the moving drum rotate in opposite directions, several peristaltic push rods on one side of the moving drum contact the vibration transmission strip through the support ball bearings. The peristaltic push rods push the contact strip side to squeeze the RO membrane roll, pressing the RO membrane roll from all sides. This allows the scale between the membrane layers of the RO membrane roll to disperse quickly, improving cleaning efficiency. When the vibration transmission strip vibrates at high speed, the peristaltic push rods can provide targeted local vibration when they contact the vibration transmission strip, enhancing the cleaning effect.
[0026] Step 7: The cleaning water is filtered and circulated through the drain tank and the inlet tank. After cleaning, tilt the opening of the cleaning tube downwards, release the clamping rod, and the RO membrane roll slides out of the cleaning tube under its own gravity.
[0027] Compared with the prior art, the beneficial effects of the present invention are:
[0028] By flipping the component, the cleaning cylinder is designed to facilitate cleaning, loading, and unloading. When the cleaning cylinder cleans the RO membrane roll, the control component, cleaning component, and reinforcing component work together to cause the RO membrane roll to move and press against its side, accelerating the separation of scale from the RO membrane roll, improving cleaning efficiency and effectiveness. Furthermore, with the connection of the clamping component, installation and disassembly are stable and quick, making it convenient and worry-free to use. Attached Figure Description

[0049] The reverse osmosis (RO) membrane mobile cleaning device disclosed in Embodiment 5 of this invention has a structure that is basically the same as that in Embodiment 4. The difference is that the opening of the cleaning cylinder 2 is sealed when it is used for cleaning, and a pressurized and sealed environment is provided in the cleaning chamber 34. The cantilever frame 31 is set in a U-shaped structure, and a sealing telescopic rod 32 is vertically provided in the center of the cantilever frame 31.

The cover 33 is inserted into the upper end of the cleaning cylinder 2 to seal the cleaning chamber 34. The structure is simple and convenient.
[0050] When cleaning a large number of RO membrane rolls 6 in a centralized manner, several of these devices can be arranged side by side, and a conveying device can be set horizontally on the side of the cleaning cylinder 2 where it is inclined to unload the material to automatically transport the RO membrane rolls 6.
[0051] A method for moving and cleaning a reverse osmosis (RO) membrane includes the following steps:
[0052] Step 1: A drive motor is horizontally installed on one side of the support frame 1. The drive motor, in conjunction with the gear, controls the flipping shaft 4 to perform flipping movement control. When the opening of the cleaning cylinder 2 is vertical, it is in the cleaning state. When the opening of the cleaning cylinder 2 is tilted upward, it is in the state of placing the RO membrane roll 6. When the opening of the cleaning cylinder 2 is tilted downward, it is in the state of automatically moving the RO membrane roll 6.
[0053] Step 2: After inserting the RO membrane roll 6 into the cleaning chamber 34 of the cleaning cylinder 2, the RO membrane roll 6 is stably inserted under the surrounding and positioning effect of the contact strip 8, and is limited by the support ring 15.
[0054] Step 3: Start the clamping telescopic rod 35 to pull down the clamping push rod 20 and the prismatic synchronous rod 22. At this time, the synchronous seat 21 drives the two clamping rods 23 to descend simultaneously. Under the action of the inclined surface of the retracting rod 25 and the abutment block 24, the two clamping rods 23 retract toward the outlet of the RO membrane roll 6, completing the clamping and fixing of the RO membrane roll 6. The clamping force can be adjusted according to the needs of the pull-down degree of the clamping telescopic rod 35.
[0055] Step 4: Connect the citric acid-based cleaning solution to one side of the water inlet tank 5 of the tilting shaft 4 through a pressurized pipeline. When tilting is required, keep the cleaning cylinder 2 vertical and seal the opening of the cleaning cylinder 2 with the cap 33. The cleaning solution is introduced into the water inlet tank 5 and flows downward from the top of the cleaning chamber 34 to clean the RO membrane roll 6.
[0056] Step 5: The motor drives the drive gear 28 to rotate. At this time, under the transmission action of the drive gear 28, the control seat 19 and the moving cylinder 7 rotate in opposite directions. When the control seat 19 rotates, under the action of the prismatic structure of the prismatic synchronizing rod 22, the synchronizing seat 21 drives the RO membrane roll 6 held by the clamping rod 23 to rotate synchronously, and then the RO membrane roll 6 and the moving cylinder 7 rotate in opposite directions.
[0057] Step Six: When the RO membrane roll 6 and the moving drum 7 rotate in opposite directions, several peristaltic push rods 10 on one side of the moving drum 7 contact the vibration transmission strip 12 through the support ball bearings 14. The peristaltic push rods 10 push the contact strip 8 to squeeze the RO membrane roll 6, and press the RO membrane roll 6 from all sides, so that the scale between the membrane layers of the RO membrane roll 6 is quickly dispersed, improving the cleaning efficiency. When the vibration transmission strip 12 vibrates at high speed, when the peristaltic push rods 10 contact the vibration transmission strip 12, it can provide targeted local vibration to enhance the cleaning effect.
[0058] Step 7: The cleaning water is filtered and circulated through the drain tank 18 and the inlet tank 5. After cleaning, tilt the opening of the cleaning cylinder 2 downwards, release the clamping rod 23, and the RO membrane roll 6 slides out of the cleaning cylinder 2 under its own gravity.

7. A method for moving and cleaning a reverse osmosis (RO) membrane, characterized in that: The reverse osmosis (RO) membrane moving cleaning method is applied to the reverse osmosis (RO) membrane moving cleaning equipment according to claim 6, and includes the following steps: Step 1: A drive motor is horizontally installed on one side of the support frame (1). The drive motor, in conjunction with the gear, controls the flipping shaft (4) to perform flipping operation control. When the opening of the cleaning cylinder (2) is vertical, it is in the cleaning state. When the opening of the cleaning cylinder (2) is tilted upward, it is in the state of placing the RO membrane roll (6). When the opening of the cleaning cylinder (2) is tilted downward, it is in the state of automatically moving the RO membrane roll (6). Step 2: After inserting the RO membrane roll (6) into the cleaning chamber (34) of the cleaning tube (2), the RO membrane roll (6) is stably inserted under the surrounding and positioning effect of the contact strip (8), and is limited by the support ring (15); Step 3: Start the clamping telescopic rod (35) to pull down the clamping push rod (20) and the prismatic synchronous rod (22). At this time, the synchronous seat (21) drives the two clamping rods (23) to descend simultaneously. Under the action of the inclined surface of the retracting rod (25) and the abutment block (24), the two clamping rods (23) retract toward the outlet of the RO membrane roll (6) to complete the clamping and fixing of the RO membrane roll (6). The clamping force can be adjusted according to the needs of the pull-down degree of the clamping telescopic rod (35). Step 4: Connect the citric acid-based cleaning solution to the water inlet tank (5) of the flipping shaft (4) through a pressurized pipeline. When tilting is required, keep the cleaning cylinder (2) vertical and seal the opening of the cleaning cylinder (2) with the cap (33). The cleaning solution is introduced into the water inlet tank (5) and flows downward from the top of the cleaning chamber (34) to clean the RO membrane roll (6). Step 5: The motor drives the drive gear (28) to rotate. At this time, under the transmission action of the drive gear (28), the control seat (19) and the moving cylinder (7) rotate in opposite directions. When the control seat (19) rotates, under the action of the prismatic structure of the prismatic synchronizing rod (22), the synchronizing seat (21) drives the RO membrane roll (6) held by the clamping rod (23) to rotate synchronously, and then the RO membrane roll (6) and the moving cylinder (7) rotate in opposite directions. Step 6: When the RO membrane roll (6) and the moving cylinder (7) rotate in opposite directions, several peristaltic push rods (10) on one side of the moving cylinder (7) contact the vibration transmission strip (12) through the support ball (14). The peristaltic push rods (10) push the contact strip (8) to squeeze the RO membrane roll (6) and press the RO membrane roll (6) from all sides. This makes the scale between the membrane layers of the RO membrane roll (6) disperse quickly, improves the cleaning efficiency, and when the vibration transmission strip (12) vibrates at high speed, when the peristaltic push rods (10) contact the vibration transmission strip (12), they can provide targeted local vibration to enhance the cleaning effect. Step 7: The cleaning water is filtered and circulated through the drain tank (18) and the inlet tank (5). After cleaning, the opening of the cleaning tube (2) is tilted downwards, the clamping rod (23) is released, and the RO membrane roll (6) slides out of the cleaning tube (2) under its own gravity.
