Description

Technical Field

[0001] This utility model belongs to the field of unit membrane assembly, specifically relating to a high-flux, low-salt reverse-mixing forward osmosis unit membrane assembly device. Background Technology

[0002] Forward osmosis unit membrane assembly equipment is a specialized device used to assemble, test, or operate forward osmosis membrane modules. Its core function is to ensure that the membrane modules work efficiently and stably during the forward osmosis process. The structure and components of such equipment will vary depending on the specific application scenario, such as laboratory research, pilot production, or industrial production.

[0003] Most forward osmosis unit membrane assembly devices on the market use traditional fixing methods to secure the unit membrane, such as using adhesives or bolts for positioning. However, these ordinary forward osmosis unit membrane assembly devices reveal a significant problem during use: unit membrane replacement is inconvenient. When unit membrane replacement or maintenance is required, operators often need to spend a lot of time and effort to disassemble the complex fixing structure, which not only reduces work efficiency but may also damage other components of the device due to frequent disassembly, increasing maintenance costs. Utility Model Content

[0004] To overcome the inconvenience of disassembling and replacing the unit membrane during use of the forward osmosis unit membrane assembly device, a novel high-flux low-salt reverse mixing forward osmosis unit membrane assembly device is proposed.

[0005] The technical solution of this utility model is as follows: a high-flux low-salt reverse-mixing forward osmosis unit membrane assembly device, including a fixed cylinder and a support plate. A fixed cover is fixedly connected to the left end of the fixed cylinder. A fixed tube is fixedly connected through the center of both ends of the fixed cover. A screw groove is opened on the outer wall of the right end of the fixed tube. A membrane tube is provided on the inner wall of the fixed cylinder. A thread is provided on the inner wall of the left end opening of the membrane tube. The thread is adapted to the screw groove. The fixed tube is adapted to the left end opening of the membrane tube. The left end edge of the membrane tube is attached to the right end of the fixed cover. A thread is provided on the inner wall of the right end of the fixed cylinder. A fixed tube is provided on the right side of the fixed cylinder. A screw groove is opened on the outer wall of the left end of the fixed tube. The screw groove is adapted to the thread. The left end of the fixed tube is attached to the right end of the membrane tube. The inner wall of the fixed tube corresponds one-to-one with the right end opening of the membrane tube.

[0006] Furthermore, a support frame is provided on the inner wall of the fixed cylinder, and the outer wall of the support frame is attached to the inner wall of the fixed cylinder.

[0007] Furthermore, the inner wall of the support frame is fitted to the outer wall of the membrane cylinder, and a sealing ring is fixed to the right end of the second fixed cover.

[0008] Furthermore, the right end of the sealing ring one is attached to the edge of the opening at the left end of the membrane tube, and the outer wall of the fixing tube two is fixedly connected to the fixing cap one, and the right end of the fixing cap one is fixedly connected to the sealing ring two.

[0009] Furthermore, a connector is fixed to the right end opening of the second fixed tube, and a sealing ring three is fixed to the left end of the second fixed tube. The sealing ring three is in contact with the edge of the right end opening of the membrane tube.

[0010] Furthermore, the left and right ends of the support plate are provided with symmetrical grooves, and the fixing cylinder is fixed to the two grooves on the same horizontal plane.

[0011] Furthermore, the right end of the sealing ring two is attached to the left end of the support plate, and the left end of the upper fixing tube one is fixed with a connecting tube, the other end of which is fixed to the left end of the lower fixing tube one.

[0012] The beneficial effects of this utility model are as follows: By using the screw groove one in conjunction with the screw thread two, the left end of the membrane tube can be threaded onto the outer wall of the fixing tube one, thereby installing the membrane tube onto the inner wall of the fixing tube. The screw groove two in conjunction with the screw thread one can be threaded onto the inner wall of the right end of the fixing tube. Rotating the fixing tube two can fit and press the right end of the membrane tube, thereby limiting and fixing the membrane tube. Compared with the existing forward osmosis unit membrane assembly device, the added fixing tube structure, with the screw thread in conjunction with the screw groove, can fix the membrane tube onto the fixing tube one, and the fixing tube two threaded onto the right end of the fixing tube can fit and press the membrane tube, thereby limiting and fixing the membrane tube. This ensures the stable operation of the membrane tube while facilitating the disassembly and maintenance of the membrane tube, improving the convenience of use. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figures 1-5 This utility model provides an embodiment of a high-flux, low-salt reverse-mixing forward osmosis unit membrane assembly device, comprising a fixed cylinder 1 and a support plate 2. A fixed cover 6 is fixedly connected to the left end of the fixed cylinder 1. A fixed tube 8 is fixedly connected through the center of both ends of the fixed cover 6. A threaded groove 7 is formed on the outer wall of the right end of the fixed tube 8. A membrane cylinder 3 is provided on the inner wall of the fixed cylinder 1. A threaded thread 15 is formed on the inner wall of the left end opening of the membrane cylinder 3. The threaded thread 15 is adapted to the threaded groove 7. The fixed tube 8 is adapted to the left end opening of the membrane tube 3. The left end edge of the membrane tube 3 is attached to the right end of the fixed cover 6. The right end inner wall of the fixed tube 1 is provided with thread 10. The right side of the fixed tube 1 is provided with fixed tube 13. The left end outer wall of the fixed tube 13 is provided with thread groove 14. Thread groove 14 is adapted to thread 10. The left end of the fixed tube 13 is attached to the right end of the membrane tube 3. The inner wall of the fixed tube 13 corresponds one-to-one with the right end opening of the membrane tube 3.

[0021] By using the screw groove 7 and the thread 15, the left end of the membrane tube 3 can be threaded onto the outer wall of the fixing tube 8, thereby installing the membrane tube 3 onto the inner wall of the fixing tube 1. By using the screw groove 14 and the thread 10, the fixing tube 13 can be threaded onto the inner wall of the right end of the fixing tube 1. Rotating the fixing tube 13 can close and press the right end of the membrane tube 3, thereby limiting and fixing the membrane tube 3. Then, by rotating the fixing tube 13, the fixing tube 13 can be disassembled. Rotating the membrane tube 3 allows for disassembly and replacement, improving the convenience of disassembly and replacement of the membrane tube 3, thus facilitating the maintenance and cleaning of the device.

[0022] Please see Figure 3 In this embodiment, a support frame 12 is provided on the inner wall of the fixed cylinder 1, and the outer wall of the support frame 12 is attached to the inner wall of the fixed cylinder 1. In use, the support frame 12 can support the inner wall of the fixed cylinder 1, which can effectively improve the strength of the fixed cylinder 1. The inner wall of the support frame 12 is attached to the outer wall of the membrane cylinder 3. A sealing ring 9 is fixed to the right end of the fixed cover 6. In use, the support frame 12 can support the membrane cylinder 3, which can improve the stability of the membrane cylinder 3 during operation.

[0023] Please see Figures 3-4In this embodiment, the right end of sealing ring 9 is attached to the edge of the left opening of membrane tube 3. A fixing cap 4 is fixed to the outer wall of fixing tube 13, and a sealing ring 11 is fixed to the right end of fixing cap 4. During use, sealing ring 9 improves the sealing between fixing cap 6 and the left opening of membrane tube 3, preventing liquid leakage. Fixing cap 4 provides installation space and support for sealing ring 11. A connector 16 is fixed to the right opening of fixing tube 13, and a sealing ring 18 is fixed to the left end of fixing tube 13. The sealing ring 18 is attached to the edge of the right opening of membrane tube 3. During use, a water inlet pipe can be connected through connector 16, allowing liquid to pass through membrane tube 3, thus ensuring stability during permeation. The sealing ring 18 improves the sealing at the edge of the right opening of membrane tube 3, further preventing liquid leakage.

[0024] Please see Figures 3-5 In this embodiment, the left and right ends of the support plate 2 are provided with symmetrical grooves 17. The fixed cylinder 1 is fixed in the two grooves 17 on the same horizontal plane. In use, the support plate 2 can support the fixed cylinder 1. The two fixed cylinders 1 can improve the permeation efficiency. The right end of the sealing ring 2 11 is attached to the left end of the support plate 2. The left end of the upper fixed tube 1 8 is fixed with the connecting tube 5. The other end of the connecting tube 5 is fixed with the left end of the lower fixed tube 1 8. In use, the sealing ring 2 11 can further improve the sealing performance of the fixed tube 2 13 and prevent liquid leakage. The connecting tube 5 can connect the upper and lower membrane cylinders 3, so that the liquid passes through the two membrane cylinders 3.

[0025] When working, connect the pipe to the upper and lower connectors 16, so that the liquid enters the upper fixed tube 2 13 from the upper connector 16, passes through the upper membrane cylinder 3 for permeation, then passes through the upper fixed tube 1 8 and is introduced into the lower fixed tube 1 8 through the connecting pipe 5, and after permeating through the lower membrane cylinder 3, it is discharged from the lower fixed tube 2 13 to the lower connector 16, thus completing the permeation work.

[0026] During maintenance, firstly, rotate the two upper and lower fixed tubes 13 to disassemble them. Then, rotate the two upper and lower membrane tubes 3 to disassemble them. Next, align the left end opening of the replaced membrane tube 3 with the outer wall of the fixed tube 8, and rotate the membrane tube 3 so that the thread 15 engages with the screw groove 7, making the left end of the membrane tube 3 completely fit against the right end of the fixed cover 6. Then, thread the fixed tube 13 onto the right end opening of the fixed tube 1, and tighten the fixed tube 13 so that the left end of the fixed tube 13 fits against the right end of the membrane tube 3. Finally, after installing both membrane tubes 3, the pipeline can be installed for permeation work.

[0027] Through the above steps, the screw groove 7, in conjunction with the thread 15, allows the left end of the membrane tube 3 to be threaded onto the outer wall of the fixing tube 8, thereby installing the membrane tube 3 onto the inner wall of the fixing tube 1. The screw groove 14, in conjunction with the thread 10, allows the fixing tube 13 to be threaded onto the inner wall of the right end of the fixing tube 1. Rotating the fixing tube 13 allows it to be pressed against and tightened onto the right end of the membrane tube 3, thereby limiting and fixing the membrane tube 3. Rotating the fixing tube 13 allows it to be disassembled, and rotating the membrane tube 3 allows it to be disassembled and replaced. This solves the problem that the disassembly and replacement of the unit membrane is inconvenient when using the forward osmosis unit membrane assembly device.
