Description

Technical Field

[0001] The present invention relates to the technical field of ultrapure water production, and in particular to a device and method for producing ultrapure water based on the reverse osmosis principle. Background Art

[0002] Ultrapure water refers to water that has undergone rigorous purification and contains almost no soluble impurities and microorganisms. It has extremely high purity and is usually used in industries and experiments that have very strict requirements on water quality. Ultrapure water is generally produced by filtering and preparing with ultra-low pore size reverse osmosis membrane reverse osmosis equipment.

[0003] Existing reverse osmosis equipment uses a reverse osmosis filter element for filtration. The reverse osmosis filter element generally uses a roll filter membrane. During filtration, water enters and exits from the top of the reverse osmosis filter element at the same time. Therefore, there may be both pure water and wastewater on the inner side of the reverse osmosis filter element, which is easy to cause cross contamination. Therefore, the publication number CN118767679A discloses a reverse osmosis filtration component, which includes a filter bottle; a reverse osmosis filter element; a lower end cover; wherein a central tube is arranged in the central hole, a partition is arranged in the central tube, the partition extends along the length direction of the central tube and divides the central tube into a clean water flow channel and a wastewater flow channel, a plurality of annular grooves are opened on the outer wall of the central tube, and at least one water through hole is opened at the bottom of the annular groove, and the water filtered by the reverse osmosis filter element enters the clean water flow channel through the water through hole, and the wastewater generated by the reverse osmosis filter element enters the wastewater flow channel through the lower end cover.

[0004] The above reverse osmosis filtration component adopts a separation design of the central tube so that the outflow paths of pure water and wastewater will not interfere with each other, thereby reducing the possibility of cross contamination between pure water and wastewater and ensuring the filtering effect of the reverse osmosis filtration component.

[0005] However, when the above-mentioned reverse osmosis components and existing reverse osmosis equipment are used, it is necessary to continuously release high pressure at the liquid inlet to complete the reverse osmosis of low-purity water, which consumes a lot of energy and has a high cost for preparing ultrapure water. At the same time, ultrapure water enters from the reverse osmosis membrane roll and is discharged from the water outlet pipe. The number of water inlet holes opened on the water outlet pipe is limited. Therefore, the filtered ultrapure water cannot be discharged through the water outlet pipe in time, resulting in a decrease in the ultrapure water outlet speed, which affects the preparation efficiency of ultrapure water.

[0006] Therefore, a new device and method for producing ultrapure water based on the reverse osmosis principle can be used to solve the shortcomings of the prior art. Summary of the invention

[0011] Preferably, the reset structure comprises a fixed plate fixedly mounted on the rotating table, an elastic reset telescopic rod is fixedly mounted on the fixed plate, and a telescopic end of the elastic reset telescopic rod is fixedly connected to the second rack.

[0012] Preferably, the supporting structure includes a plate body fixedly mounted on the bottom of the rotating table, a supporting telescopic rod is fixedly mounted on the plate body, a connecting plate is fixedly mounted on the driving end of the supporting telescopic rod, the connecting plate is fixedly connected to the centrifugal ball, and a locking component matching the connecting plate is mounted on the rotating table.

[0013] Preferably, the locking component includes a fixing frame fixedly mounted on the bottom of the rotating table, an electromagnetic plate is fixedly mounted on the fixing frame, a permanent magnet plate matching the electromagnetic plate is fixedly mounted on the connecting plate, and an energizing component matching the electromagnetic plate is mounted on the tubular liquid outlet support.

[0014] Preferably, the energizing component includes a first conductive ring rotatably mounted on a tubular liquid outlet support, a second conductive ring matching with the first conductive ring is sleeved on the tubular liquid outlet support, a connecting tube is installed on each of the first conductive ring and the second conductive ring, the connecting tube on the first conductive ring is fixedly connected to the first conductive ring and the electromagnetic plate, the connecting tube on the second conductive ring is rotatably connected to the second conductive ring and the electromagnetic plate, a telescopic design is adopted at one end of the connecting tube on the second conductive ring close to the electromagnetic plate, and a moving mechanism matching with the second conductive ring is installed on the driving disk and the rotating table.

[0017] The present invention also provides a method for producing ultrapure water according to the reverse osmosis principle, comprising the above-mentioned device for producing ultrapure water according to the reverse osmosis principle, and further comprising the following steps: S1. Introduce low-purity water from the liquid inlet pipe into the high-pressure pipe, and pressurize the introduced low-purity water through external pressurizing equipment, so that the low-purity water pressure in the high-pressure pipe is stronger than the natural osmotic pressure of the low-purity water and ultra-purity water. During the pressurization process, close the water outlet at the bottom of the high-pressure pipe through the electric control valve; S2. The pressurized low-purity water will enter the filter membrane roll through the liquid outlet hole on the high-pressure pipe. Under the blocking effect of the side baffle, the ultra-pure water filtered by the filter membrane roll layer by layer will seep out from the filter membrane roll from the inside to the outside, pass through the steel mesh support frame and enter the water outlet cover; S3. When low-purity water enters the high-pressure pipe, the driving disc drives the rotating table to rotate, and the rotating table drives the high-pressure pipe to rotate. The high-speed rotation of the rotating table will generate centrifugal force, which will drive the clamping assembly to operate and clamp the water outlet cover, so that the water outlet cover rotates with the high-pressure pipe, so that the low-purity water in the high-pressure pipe has a certain centrifugal force, so that the low-purity water diffuses faster after entering the filter membrane roll, and accelerates the water outlet speed of the water outlet rotating ring, generating negative pressure suction. The generated centrifugal force is used to share part of the boosting energy of the external boosting equipment, thereby reducing the energy consumption of the external boosting equipment; S4. The clamping assembly will change shape as the rotating table rotates, and intermittently clamp the water outlet housing, so that the water outlet housing rotates intermittently. The water outlet housing stops rotating to maintain the osmotic pressure inside the water outlet housing.

[0018] Compared with the prior art, the present invention has the following advantages: 1. When preparing ultrapure water, the ultrapure water production device introduces low-purity water from a high-pressure pipe and then outputs it from the filter membrane roll. After the low-purity water is pressed out of the high-pressure pipe, its pressure will be released instantly, and the molecular movement will be accelerated, which is conducive to the diffusion of low-purity water, thereby improving the water outlet efficiency of low-purity water. At the same time, the water outlet area of ​​the filter membrane roll is large, so the ultrapure water outlet efficiency is high, which effectively improves the preparation efficiency of ultrapure water.

[0019] 2. When preparing ultrapure water, the ultrapure water production device drives the high-pressure pipe to rotate by setting a rotatable rotating table, so that the high-pressure pipe rotates at high speed during the water discharge process to generate a centrifugal force of a certain intensity. Under the action of the centrifugal force, the low-purity water has an extrusion force squeezed out from the liquid outlet of the high-pressure pipe, and the reverse osmosis pressure is reached with the additional pressure. This can reduce the additional pressure and reduce energy consumption, thereby reducing the preparation cost of ultrapure water. In addition, the centrifugal force generated by the high-speed rotation will also accelerate the diffusion speed of the low-purity water in the filter membrane roll, so that the low-purity water diffuses more evenly in the filter membrane roll, avoiding the occurrence of local blockages that cause the reverse osmosis water path to be blocked.

[0020] 3. When preparing ultrapure water, the ultrapure water production device clamps the water outlet cover by setting a clamping assembly, and adjusts the position of the clamping plate in the clamping assembly by using an energizing assembly, so that the clamping assembly intermittently clamps the water outlet cover. The rotation of the high-pressure pipe drives the water outlet cover to rotate intermittently through the clamping assembly, thereby driving the ultrapure water in the water outlet cover to rotate, generating centrifugal force, accelerating the discharge of ultrapure water, and generating negative pressure inside the water outlet cover when draining water, thereby increasing the reverse osmosis force, thereby reducing the additional pressure that needs to be applied and further reducing energy consumption.

[0021] In summary, the present invention adopts a reverse water inlet and outlet method to prepare ultrapure water by reverse osmosis, and drives the filter membrane roll to rotate during the reverse osmosis process to generate centrifugal force, change the reverse osmosis water outlet speed, and improve the reverse osmosis water outlet efficiency. It not only effectively reduces the energy consumption of ultrapure water reverse osmosis preparation, but also can increase the diffusion rate and uniformity of low-purity water, thereby improving the preparation efficiency of ultrapure water.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example 1: Reference Figure 1-Figure 7 , a device for producing ultrapure water according to the reverse osmosis principle, comprising a reverse osmosis body, and also comprising a tubular liquid outlet support 4, the tubular liquid outlet support 4 is composed of a support and a concentrated liquid discharge pipe, and the concentrated water after filtration will be discharged from the concentrated liquid discharge pipe; The reverse osmosis device body comprises a water outlet housing 1, a cover body is fixedly mounted on the water outlet housing 1, a high-pressure pipe 7 is rotatably mounted inside the water outlet housing 1, a liquid inlet pipe 5 is fixedly connected to the top of the high-pressure pipe 7, a plurality of liquid outlet holes 11 are opened on the high-pressure pipe 7, and a filter membrane roll 10 is wrapped outside the high-pressure pipe 7; The filter membrane roll 10 is a completely rolled filter membrane, which is composed of a reverse osmosis membrane and a separator, and the separator is used for the circulation of water.

[0026] A steel mesh support frame 9 is fixedly installed on the outside of the filter membrane roll 10, and side baffles 8 matching the filter membrane roll 10 are fixedly installed on both sides of the steel mesh support frame 9. A water outlet rotating ring 2 is rotatably installed on the outside of the water outlet outer cover 1, and a water pipe is fixedly installed on the water outlet rotating ring 2 for discharging ultrapure water.

[0027] The function of the side baffle 8 is to block the two ends of the filter membrane roll 10 to prevent low-purity water from flowing out from both sides of the filter membrane roll 10 and ensure that the low-purity water is filtered layer by layer through the filter membrane roll 10.

[0028] The low-purity water is introduced into the high-pressure pipe 7 from the liquid inlet pipe 5, and the introduced low-purity water is pressurized by an external pressurizing device, so that the low-purity water pressure in the high-pressure pipe 7 is stronger than the natural osmotic pressure of the low-purity water and ultra-purity water; The pressurized low-purity water will enter the filter membrane roll 10 through the liquid outlet 11 on the high-pressure pipe 7. Under the blocking effect of the side baffle 8, the ultra-pure water filtered through the filter membrane roll 10 layer by layer will seep out from the filter membrane roll 10 from the inside to the outside, pass through the steel mesh support frame 9 and enter the water outlet cover 1.

[0029] The function of the steel mesh support frame 9 is to wrap and fix the filter membrane roll 10 to prevent the filter membrane roll 10 from automatically unfolding under the action of its own elastic force.

[0030] Embodiment 2: This embodiment is different from the embodiment 1 in that: Figure 1 , Figure 5-Figure 15 A rotating table 3 is rotatably mounted on the tubular liquid outlet support 4, and a driving disk 22 matched with the rotating table 3 is fixedly mounted on the tubular liquid outlet support 4; The driving disk 22 includes a fixed disk and a driving motor. The fixed disk is fixedly connected to the tubular liquid outlet support 4, the driving motor is fixedly connected to the fixed disk, the driving end of the driving motor is fixedly connected to the rotating table 3, and a liquid outlet conduit is fixedly connected to the side of the tubular liquid outlet support 4, and the filtered concentrated liquid will be discharged from the liquid outlet conduit.

[0031] A clamping assembly 6 matched with the water outlet housing 1 is installed on the rotating platform 3 , and an electric control valve 15 fixedly connected to the bottom of the high-pressure pipe 7 is fixedly installed on the rotating platform 3 , and the electric control valve 15 is rotatably connected to the tubular liquid outlet support 4 .

[0032] During the pressurization process, the water outlet at the bottom of the high-pressure pipe 7 is closed by the electric control valve 15. The electric control valve 15 is opened and closed intermittently, and drainage is performed when it is opened, and filtering is performed when it is closed.

[0033] The clamping assembly 6 includes a plurality of sliding plates 13 slidably mounted on the rotating table 3, each sliding plate 13 is fixedly mounted with a frame, each frame is fixedly mounted with a clamping plate 12 matched with the water outlet outer cover 1, and a plurality of linkage mechanisms 16 matched with the corresponding sliding plates 13 are installed on the rotating table 3.

[0034] The linkage mechanism 16 includes a first rack 17 fixedly mounted on the sliding plate 13, a second rack 18 slidably mounted on the rotating table 3, a first gear 19 rotatably mounted on the rotating table 3 and meshing with the first rack 17 and the second rack 18, a centrifugal ball 14 is fixedly mounted on the second rack 18, and a reset structure matched with the second rack 18 and a support structure matched with the centrifugal ball 14 are installed on the rotating table 3.

[0035] As the rotating table 3 rotates at a high speed, the centrifugal ball 14 will be driven to rotate. The rotation of the centrifugal ball 14 will generate centrifugal force. Under the action of the centrifugal force, the centrifugal ball 14 will be driven to move in the direction away from the center point of the rotating table 3, thereby driving the second rack 18 to move. The second rack 18 will drive the first rack 17 to move toward the center point of the rotating table 3 through the first gear 19, thereby driving the clamping plate 12 to move toward the side close to the water outlet housing 1 through the sliding plate 13 and the frame, so that the clamping plate 12 and the water outlet housing 1 are abutted against each other to clamp the water outlet housing 1. The faster the rotation speed, the greater the centrifugal force of the centrifugal ball 14, and the greater the clamping force. At this time, the rotating table 3 not only drives the high-pressure pipe 7 to rotate, but also drives the water outlet housing 1 to rotate through the clamping assembly 6.

[0036] When the water outlet outer cover 1 rotates, the ultrapure water in the water outlet rotating ring 2 will rotate, generating centrifugal force, and flowing out from the water pipe at high speed. The outflow will cause the ultrapure water in the upper part of the water outlet outer cover 1 to be discharged, while the ultrapure water in the lower part of the water outlet outer cover 1 will still remain in the water outlet outer cover 1 (only half of the water is discharged each time, and the other half is used to maintain the osmotic pressure in the water outlet outer cover 1).

[0037] The reset structure includes a fixed plate fixedly mounted on the rotating table 3 , on which an elastic reset telescopic rod 21 is fixedly mounted, and a telescopic end of the elastic reset telescopic rod 21 is fixedly connected to the second rack 18 .

[0038] As the rotation speed of the rotating table 3 decreases, the centrifugal force of the centrifugal ball 14 decreases. At this time, the second rack 18 needs to be pulled back to the original position by the elastic reset telescopic rod 21 to reset the centrifugal ball 14 .

[0039] The supporting structure includes a plate body fixedly mounted on the bottom of the rotating table 3, on which a supporting telescopic rod 20 is fixedly mounted, and a connecting plate is fixedly mounted on the driving end of the supporting telescopic rod 20, the connecting plate is fixedly connected to the centrifugal ball 14, and a locking component matching the connecting plate is installed on the rotating table 3.

[0040] Since the centrifugal ball 14 is heavy, it will be separated from the rotating table 3 when the centrifugal ball 14 is rotated and thrown out. At this time, the centrifugal ball 14 is in a suspended state, which will increase the friction between the second rack 18 and the rotating table 3, thereby increasing the movement resistance of the second rack 18 on the rotating table 3, affecting the normal sliding of the second rack 18. If a sliding distance is required, the required rotational centrifugal force between the unsupported centrifugal ball 14 and the supported centrifugal ball 14 is different, and the unsupported centrifugal ball 14 requires a higher rotation speed to be pushed.

[0041] A supporting structure is used here to support the centrifugal ball 14. The weight of the centrifugal ball 14 will be borne by the supporting telescopic rod 20, so that the friction between the second rack 18 and the rotating table 3 is reduced to a minimum, so that the second rack 18 can move more smoothly on the rotating table 3. Under the premise of ensuring the centrifugal force, the required rotation speed is lower and the energy consumption is lower.

[0042] Control the rotation of the water outlet cover 1: the locking component includes a fixed frame fixedly installed at the bottom of the rotating platform 3, an electromagnetic plate 34 is fixedly installed on the fixed frame, a permanent magnet plate 33 matched with the electromagnetic plate 34 is fixedly installed on the connecting plate, and an energized component matched with the electromagnetic plate 34 is installed on the tubular liquid outlet support 4.

[0043] When the electromagnetic plate 34 is energized, it will generate suction force on the permanent magnetic plate 33, pulling the permanent magnetic plate 33 toward the center of the rotating platform 3, so that the centrifugal ball 14 is reset. At this time, the movement of the centrifugal ball 14 will drive the clamping plate 12 to move, so that the clamping plate 12 is separated from the water outlet housing 1, so that the water outlet housing 1 cannot rotate together with the rotating platform 3; After the electromagnetic plate 34 is powered off, the permanent magnet plate 33 loses the suction force of the electromagnetic plate 34 , and the centrifugal force of the centrifugal ball 14 will pull the second rack 18 again, so that the clamping plate 12 clamps the water outlet housing 1 .

[0044] The energized component includes a first conductive ring 23 rotatably mounted on a tubular liquid outlet support 4, a second conductive ring 24 matching the first conductive ring 23 is sleeved on the tubular liquid outlet support 4, a connecting tube 32 is installed on each of the first conductive ring 23 and the second conductive ring 24, the connecting tube 32 on the first conductive ring 23 is fixedly connected to the first conductive ring 23 and the electromagnetic plate 34, the connecting tube 32 on the second conductive ring 24 is rotatably connected to the second conductive ring 24 and the electromagnetic plate 34, the end of the connecting tube 32 on the second conductive ring 24 close to the electromagnetic plate 34 adopts a telescopic design, and a moving mechanism matching the second conductive ring 24 is installed on the driving disk 22 and the rotating table 3.

[0045] After the first conductive ring 23 contacts the second conductive ring 24 , the electromagnetic plate 34 will be energized to generate suction. This part is an existing electrical technology and no specific circuit description is given.

[0046] The rotation of the rotating table 3 drives the centrifugal ball 14 to rotate, and then drives the first conductive ring 23 and the second conductive ring 24 to rotate through the connecting tube 32 (the first conductive ring 23 and the second conductive ring 24 will rotate around the tubular liquid outlet support 4).

[0047] The end of the connecting tube 32 on the second conductive ring 24 close to the electromagnetic plate 34 is designed to be telescopic, so that when the second conductive ring 24 moves, it will not get stuck, allowing the second conductive ring 24 to move smoothly.

[0048] The moving mechanism includes a plurality of screw rods 30 rotatably mounted on the driving disk 22, each screw rod 30 is threadedly rotatably mounted with a threaded sleeve 31, and a moving ring 25 is fixedly mounted on the plurality of threaded sleeves 31, and the moving ring 25 is rotatably connected to the second conductive ring 24; A second gear 28 is fixedly mounted on each screw rod 30, a plurality of first incomplete gears 26 matching the corresponding second gears 28 are fixedly mounted on the rotating table 3, a plurality of second incomplete gears 27 matching the corresponding second gears 28 are fixedly mounted on the second conductive ring 24, and the diameter of the first incomplete gear 26 is greater than the diameter of the second incomplete gear 27.

[0049] As the rotating table 3 and the second conductive ring 24 rotate, the first incomplete gear 26 and the second incomplete gear 27 are driven to rotate. The first incomplete gear 26 and the second incomplete gear 27 are arranged in a staggered manner. When the first incomplete gear 26 is disengaged from the second gear 28, the second incomplete gear 27 is meshed with the second gear 28. After the second incomplete gear 27 is disengaged from the second gear 28, the first incomplete gear 26 is meshed with the second gear 28 again (because the diameter of the second incomplete gear 27 is smaller than the diameter of the first incomplete gear 26, the two diameters are The difference is twice the diameter of the second gear 28, and the second gear 28 is located between the rotation path of the first incomplete gear 26 and the rotation path of the second incomplete gear 27). When the first incomplete gear 26 is meshed with the second gear 28, it will drive the second gear 28 to rotate clockwise. When the second incomplete gear 27 is meshed with the second gear 28, the second gear 28 will rotate counterclockwise (the clockwise and counterclockwise here are for the convenience of description, and the specific rotation direction needs to be determined according to the specific reference figure), thereby realizing the forward and reverse rotation of the second gear 28; The rotation of the second gear 28 will drive the screw rod 30 to rotate, thereby driving the threaded sleeve 31 to move back and forth on the screw rod 30, thereby driving the second conductive ring 24 to move up and down to achieve intermittent power supply. From the above, it can be seen that intermittent power supply can achieve intermittent rotation of the water outlet housing 1.

[0050] If the water outlet housing 1 needs to be kept rotating continuously, the permanent magnetic plate 33 can be replaced with an insulating plate. If the water outlet housing 1 needs to remain stationary, the electromagnetic plate 34 needs to be replaced with a permanent magnet that attracts the permanent magnetic plate 33.

[0051] The specific operation steps of this device are as follows: The low-purity water is introduced into the high-pressure pipe 7 from the liquid inlet pipe 5, and the introduced low-purity water is pressurized by an external pressurizing device, so that the low-purity water pressure in the high-pressure pipe 7 is stronger than the natural osmotic pressure of the low-purity water and ultra-purity water. During the pressurization process, the water outlet at the bottom of the high-pressure pipe 7 is closed by the electric control valve 15; The pressurized low-purity water will enter the filter membrane roll 10 through the liquid outlet 11 on the high-pressure pipe 7. Under the blocking effect of the side baffle 8, the ultra-pure water filtered by the filter membrane roll 10 will seep out from the filter membrane roll 10 from the inside to the outside, pass through the steel mesh support frame 9 and enter the water outlet housing 1. When low-purity water enters the high-pressure pipe 7, the driving disc 22 drives the rotating table 3 to rotate, and the rotating table 3 drives the high-pressure pipe 7 to rotate. The high-speed rotation of the rotating table 3 generates centrifugal force, which drives the clamping assembly 6 to operate and clamp the water outlet cover 1, so that the water outlet cover 1 rotates together with the high-pressure pipe 7, so that the low-purity water in the high-pressure pipe 7 has a certain centrifugal force, so that the low-purity water diffuses faster after entering the filter membrane roll 10, and accelerates the water outlet speed of the water outlet rotating ring 2, generating negative pressure suction, and the generated centrifugal force is used to share part of the boosting energy of the external boosting equipment, thereby reducing the energy consumption of the external boosting equipment; The clamping assembly 6 will change shape as the rotating platform 3 rotates, and intermittently clamp the water outlet housing 1, so that the water outlet housing 1 rotates intermittently. The water outlet housing 1 stops rotating to maintain the osmotic pressure in the water outlet housing 1.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

10. A method for producing ultrapure water according to the reverse osmosis principle, used in the device for producing ultrapure water according to the reverse osmosis principle as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: S1, introducing low-purity water from the liquid inlet pipe (5) into the high-pressure pipe (7), and pressurizing the introduced low-purity water through an external pressurizing device, so that the pressure of the low-purity water in the high-pressure pipe (7) is greater than the natural osmotic pressure of the low-purity water and ultra-purity water. During the pressurizing process, the water outlet at the bottom of the high-pressure pipe (7) is closed by the electric control valve (15); S2, the pressurized low-purity water will enter the filter membrane roll (10) through the liquid outlet hole (11) on the high-pressure pipe (7), and under the blocking effect of the side baffle (8), the ultra-pure water filtered through the filter membrane roll (10) will seep out from the filter membrane roll (10) from the inside to the outside, pass through the steel mesh support frame (9) and enter the water outlet cover (1); S3. When the low-purity water enters the high-pressure pipe (7), the driving disc (22) drives the rotating table (3) to rotate, and the rotating table (3) drives the high-pressure pipe (7) to rotate. The high-speed rotation of the rotating table (3) generates centrifugal force, which drives the clamping assembly (6) to operate and clamp the water outlet cover (1), so that the water outlet cover (1) rotates together with the high-pressure pipe (7), so that the low-purity water in the high-pressure pipe (7) has a certain centrifugal force, so that the low-purity water diffuses faster after entering the filter membrane roll (10), and accelerates the water outlet speed of the water outlet rotating ring (2), generating negative pressure suction. The generated centrifugal force is used to share part of the boosting energy of the external boosting equipment, thereby reducing the energy consumption of the external boosting equipment; S4. The clamping assembly (6) changes shape as the rotating platform (3) rotates, and intermittently clamps the water outlet housing (1), causing the water outlet housing (1) to intermittently rotate. The water outlet housing (1) stops rotating to maintain the osmotic pressure in the water outlet housing (1).
