Description

A reverse osmosis device Technical Field

[0001] This invention belongs to the field of water treatment technology, specifically a reverse osmosis device. Background Technology

[0002] Reverse osmosis (RO) is a membrane separation technology that uses pressure difference as the driving force. RO modules are an important water treatment technology, widely used in drinking water purification, industrial treatment, and seawater desalination. Traditional RO systems have a fixed water flow direction; during operation, raw water flows into one end of the membrane element, while concentrated water (wastewater) continuously discharges from the other end. This unidirectional flow easily leads to severe concentration polarization at the membrane element's end, resulting in a high risk of scaling and fouling. In contrast, reverse RO systems periodically reverse the flow direction of raw water and concentrated water. For example, in the first half of the cycle, water flows from end A to end B; in the second half of the cycle, the system automatically switches the flow from end B to end A. However, after prolonged use, impurities can become trapped in the micropores of the RO module, causing blockage and affecting its performance. Therefore, timely cleaning of the RO module is essential.

[0003] The prior art discloses a Chinese patent with application number CN 118771536 A, which discloses a reverse osmosis component with internal circulation. The internal circulation reverse osmosis component is described in which a water pump delivers cleaning water to a return water tank through a water supply pipe, and a chemical agent is added to the return water tank through a chemical dosing pipe to mix with the cleaning water, thereby separating the cleaning water from impurities. This allows the cleaning water to continuously clean the reverse osmosis filter element in the filter cartridge. When the outlet leaves the circulation water pipe, the circulation water pipe is blocked by the outlet ring, preventing the cleaning water from entering the filter cartridge from the circulation water pipe. When the cleaning water stays in the return water tank, it can fully mix with the chemical agent, thus avoiding the cleaning water carrying a large amount of impurities from re-contacting the reverse osmosis filter element and improving the effect of circulation filtration.

[0004] Although the above-mentioned device can add chemicals during water treatment, it still has some drawbacks:

[0005] 1. An additional driving source is required when adding the drug, and the dosage cannot be kept consistent, which may result in adding too much or too little.

[0006] 2. During equipment use, it is impossible to discharge the impurities cleaned inside the device, causing great inconvenience to users. Summary of the Invention

[0018] The beneficial effects of this invention are:

[0019] 1. This invention divides the treatment tank into an injection chamber and a treatment chamber using a pressure plate. This allows the pressure plate to pressurize the water flow as it moves within the treatment tank. During reverse osmosis treatment, impurities in the water can easily cause blockages in the treatment equipment and slow water flow.

Furthermore, multiple sets of side boxes and branch pipes are provided, which can efficiently discharge water into the treatment chamber and ensure the normal operation of water flow in the remaining branch pipes even if any branch pipe is blocked.

[0021] 3. When the cleaning unit of this invention performs circumferential agitation to clean the dirt on the inner wall of the treatment tank, the opening of the cylinder can also drive the cleaning component to move linearly left and right inside the treatment tank, thereby effectively expanding the cleaning range of the cleaning unit on the inner wall of the treatment tank. Through the setting of the cleaning component, after the cleaning unit cleans the dirt on the inner wall of the treatment tank, it can separately discharge the mud and impurities scraped and collected by the cleaning unit without affecting the overall operation of the device. This allows the entire device to discharge the cleaned impurities during operation.

[0022] 4. The dosing unit of this invention enables the cleaning unit to automatically and periodically add chemicals to the treatment tank while cleaning the dirt inside the treatment tank. Compared with manual dosing, this invention can ensure that the dosage of chemicals is consistent each time and the dosing intervals are equal, which greatly saves manpower and makes the reverse osmosis device more effective in treating wastewater.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please refer to Figures 1-7. This invention is a reverse osmosis device, including a treatment tank 1. A connecting frame 10 is fixedly installed at one end of the treatment tank 1. A filling tank 11 is rotatably installed on one side of the connecting frame 10 via an electric slider. A water storage chamber 12 is provided inside the filling tank 11. A central sleeve 13, fixed to the filling tank 11, is provided in the middle of the connecting frame 10. A threaded rod 14 is rotatably installed inside the central sleeve 13. A pressure plate 15, which slides within the inner cavity of the treatment tank 1, is rotatably installed at one end of the threaded rod 14. The pressure plate 15 pressurizes the treated water... The tank 1 is divided into an infusion chamber 20 and a treatment chamber 21. The outer wall of the treatment tank 1 is provided with a number of side boxes 22 that communicate with the infusion chamber 20. A branch pipe 221 communicating with the treatment tank 1 is provided on one side of the side box 22. A filter plate 23 is detachably installed in the middle of the treatment tank 1. A control component is provided on one side of the side box 22 and opened on the inner wall of the treatment tank 1. A cleaning section is provided at the end of the treatment tank 1 away from the connecting frame 10. A cleaning component is provided in the middle section of the bottom of the treatment tank 1. A dosing section for quantitatively adding the agent into the treatment tank 1 is also provided above the cleaning section.

[0035] In traditional RO, the end of the membrane element is the area with the most severe fouling and scaling because the salt concentration is the highest there. However, the reverse RO system used in this application changes the flow direction periodically, turning the high-fouling area at the end of the cycle into the feed water end of the next cycle. The high-velocity feed water can effectively flush away the pollutants and scale precursors that were just beginning to form in the previous cycle. The advantage is that it greatly delays the degradation of membrane performance, maintains a more stable permeate flow rate and desalination rate. Using stimulus-responsive polymers (such as temperature-sensitive / photosensitive hydrogels) as the membrane matrix, the pore size is dynamically adjusted by external signals (temperature, light) to achieve a balance between antifouling and high-efficiency separation, thereby improving the retention efficiency of pollutants of different particle sizes.

[0036] The filling tank 11 is connected to an external water pump via a pipe. The water pump fills the filling tank 11 with the water that needs to be treated. By opening the control component, the side tank 22 can be connected to the filling chamber 20 in the treatment tank 1, so that the water in the filling chamber 20 can flow into the treatment chamber 21 through the side tank 22 and the branch pipe 221. The pressure plate 15 divides the treatment tank 1 into the filling chamber 20 and the treatment chamber 21. The pressure plate 15 can pressurize the water flow when it moves in the treatment tank 1. Since impurities in the water can easily cause blockage of the treatment equipment and slow water flow during reverse osmosis treatment, pressurizing the water flow can effectively prevent the water flow from slowing down due to blockage. On the other hand, it can also clear the impurities in the water film during water treatment, so as to avoid poor water treatment effect of the reverse osmosis device.

[0037] Secondly, the water in the water storage chamber 12 flows into the injection chamber 20 through the channel between the inner wall of the connecting frame 10 and the outside of the central sleeve 13. The side boxes 22 and branch pipes 221 are configured to selectively discharge the water in the injection chamber 20 into the treatment chamber 21 for subsequent treatment. Furthermore, there are multiple sets of side boxes 22 and branch pipes 221, which can efficiently discharge water into the treatment chamber 21. Even if any branch pipe 221 is blocked, the remaining branch pipes 221 can still ensure the normal operation of the water flow. Moreover, when multiple side boxes 22 control the water flow, they can be operated synchronously without the need for multiple drives to control it.

[0038] When the cleaning unit cleans the dirt on the inner wall of the treatment tank 1 by circumferential agitation, the opening of the cylinder can also drive the cleaning component to move linearly left and right inside the treatment tank 1, thereby effectively expanding the cleaning range of the cleaning unit on the inner wall of the treatment tank 1. The cleaning component can be set up so that after the cleaning unit cleans the dirt on the inner wall of the treatment tank 1, it can separately discharge the mud and impurities scraped and collected by the cleaning unit without affecting the overall operation of the device. This allows the entire device to discharge the cleaned impurities during operation.

[0039] The addition of a dosing unit allows the cleaning unit to simultaneously and automatically add chemicals to the treatment tank 1 at regular intervals while cleaning the tank. Compared to manual dosing, this invention ensures consistent dosage and equal dosing intervals, significantly saving manpower and improving the treatment effect of the reverse osmosis device when treating wastewater.

[0040] The control assembly includes a moving groove 222 located inside multiple side boxes 22 and formed on the inner wall of the processing tank 1. A regulating groove 223 communicating with the moving groove 222 is formed on one side of the processing tank 1. A rotating ring 226 is rotatably installed in the moving groove 222. Multiple openings corresponding to the multiple side boxes 22 are formed on the rotating ring 226. A connecting rod 225 fixed to the rotating ring 226 slides in the regulating groove 223. A gear ring 224 coaxially connected to the processing tank 1 is provided on the outside of the connecting frame 10. One end of the gear ring 224 is fixed to the connecting rod 225. A drive rod 227 threadedly connected to the processing tank 1 is provided on one side of the gear ring 224. A drive wheel 228 meshing with the gear ring 224 is fixedly installed on the drive rod 227.

[0041] When controlling the connection between the side box 22 and the processing tank 1, the drive rod 227 is rotated clockwise. As the drive rod 227 rotates, it simultaneously drives the drive wheel 228 to rotate clockwise. The drive wheel 228, while rotating clockwise, meshes with the gear ring 224, thereby driving the gear ring 224 to rotate counterclockwise. When the gear ring 224 rotates counterclockwise, it rotates within the regulating groove 223 via the connecting rod 225, thus simultaneously driving the rotating ring 226 to rotate within the moving groove 222. As the rotating ring 226 rotates, the several openings on the rotating ring 226 correspond one-to-one with the various side boxes 22. The side box 22 is connected to the filling chamber 20 inside the treatment tank 1. When water is added into the filling chamber 20, the water flows to the side box 22 through the opening, and then the water is discharged into the treatment chamber 21 inside the treatment tank 1 through the branch pipe 221 for treatment. When water needs to be supplied to the treatment chamber 21, the drive rod 227 is rotated counterclockwise. At this time, the opening on the rotating ring 226 is misaligned with the corresponding side box 22 as the rotating ring 226 rotates. At this time, one side of the side box 22 is blocked by the rotating ring 226, and the water in the filling chamber 20 cannot flow into the treatment chamber 21.

[0042] The cleaning unit includes a rotating sleeve 30 rotatably connected to the treatment tank 1. One end of the rotating sleeve 30 is slidably mounted with an internal rod 31 located inside the treatment tank 1. The inner cavity of the rotating sleeve 30 is provided with a spring, and the two ends of the spring are respectively connected to the end of the internal rod 31 and one end of the inner cavity of the rotating sleeve 30. Two symmetrical fixing rings 32 are arranged on the internal rod 31. The inner side of the fixing ring 32 is provided with a slot opened on the outside of the internal rod 31. A locking strip fixed to the inner side wall of the fixing ring 32 slides in the slot. Multiple side frames 33 arranged circumferentially are installed between the two fixing rings 32. A sliding rod 314 is slidably mounted in the middle of the side frame 33. A cleaning plate 316 is fixedly mounted on one end of the sliding rod 314.

[0043] The rotating sleeve 30 is connected to the processing bucket 1 via a motor. When the motor is turned on, it drives the rotating sleeve 30 to rotate, which in turn drives the built-in rod 31 to rotate. When the built-in rod 31 rotates, it drives the cleaning plate 316 to rotate via the fixing ring 32. In the initial state, due to the spring setting, the cleaning plate 316 can be in contact with the inside of the processing bucket 1. At this time, the cleaning plate 316 follows the rotation of the built-in rod 31 to scrape and clean the inside of the processing bucket 1. At the same time, the cylinder is activated to perform reciprocating extension and retraction. When the cylinder performs extension and retraction, it intermittently pushes the cleaning plate 316 and the fixing ring 32 on the rotating sleeve 30, thereby enabling the cleaning plate 316 to rotate and scrape the inside of the processing bucket 1, and also to perform linear movement to clean the inside of the processing bucket 1, so as to enhance the cleaning range.

[0044] A central ring 311 is fixedly installed in the middle section of the built-in rod 31, which is arranged between multiple side frames 33. Multiple sliding rods 314 pass through and slide within the central ring 311. An abutment rod 312 is slidably installed between the central ring 311 and the built-in rod 31. A conical block 313 located in the central ring 311 is fixedly installed at one end of the abutment rod 312. A spring is sleeved on the outside of the abutment rod 312. Multiple wedge blocks 315 are arranged on the outside of the conical block 313. The multiple wedge blocks 315 are respectively connected to the multiple sliding rods 314. A spring is sleeved on the outside of the sliding rod 314, and the spring is located between the wedge block 315 and the inner wall of the central ring 311 for abutment. A cylinder fixed to the inner wall of the processing tank 1 is also provided on one side of the side frame 33.

[0045] The cleaning assembly includes a tapered tube 41, a vertically arranged central tube 42 installed in the middle of the tapered tube 41, and a drain outlet 43 connected to the treatment tank 1 on the inner wall of the tapered tube 41 at the inclined side. A detachable blockage bucket 44 is installed on the vertical section at the bottom of the drain outlet 43.

[0046] The inner walls of the central tube 42 and the tapered tube 41 are provided with a through annular groove 45. A sealing plate 46 is slidably installed in the annular groove 45. A shaft 47 is fixedly installed at the bottom center of the sealing plate 46. A spring is connected between the upper end face of the sealing plate 46 and the processing tank 1.

[0047] The dosing unit includes a dosing tank 34, which is fixedly connected to the treatment tank 1. A bottom ring 341 is fixedly installed in the middle of the inner cavity of the dosing tank 34. The upper end of the bottom ring 341 is concave in an inverted cone shape. A through round hole is opened between the bottom ring 341 and the bottom of the dosing tank 34. A lifting rod 343 is slidably installed inside the bottom ring 341. A discharge plug 342 is fixedly installed on the top of the lifting rod 343. A receiving frame 344 is sleeved on the outside of the lifting rod 343. A discharge pipe 345 is arranged on one side of the receiving frame 344. One end of the discharge pipe 345 is connected to the inner cavity of the treatment tank 1.

[0048] When the lifting rod 343 slides upward within the bottom ring 341, it simultaneously drives the discharge plug 342 to move upward. As the discharge plug 342 moves upward, it removes the blockage on the bottom ring 341. At this time, the agent in the dosing tank 34 falls into the receiving frame 344 through the round hole in the bottom ring 341, and then flows into the treatment tank 1 through the discharge pipe 345.

[0049] The bottom of the lifting rod 343 has a rectangular groove, in which a round rod slides. A cam 346 is fixedly installed on the rotating sleeve 30. One end of the cam 346 is hinged to a push plate 347, and one end of the push plate 347 is fixed to the round rod.

[0050] The treatment tank 1 has two symmetrical annular pipes 51 on its outside. A threaded pipe 52 is installed between the two annular pipes 51. Multiple side pipes 53 are provided on one side of the annular pipe 51, and a water outlet pipe 54 connected to the bottom of the treatment tank 1 is provided on the other side of the annular pipe 51.

Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the concept of the invention or exceed the scope defined in the claims, they should all fall within the protection scope of the present invention.
