Description

Technical Field

[0001] This application relates to the field of greywater treatment technology, and in particular to a reverse osmosis membrane device for greywater treatment. Background Technology

[0002] In the process of wastewater treatment, reverse osmosis membrane equipment plays a crucial role. Through reverse osmosis membrane filter cartridges, water is deeply filtered to remove impurities such as salt, microorganisms, and fine particles, thereby purifying the water. However, during actual operation, fine powder easily adheres to the filter pores of the reverse osmosis membrane. With prolonged use, due to factors such as water flow pressure, the pore size of the reverse osmosis membrane gradually increases, leading to filter cartridge clogging, a significant reduction in water output, and severely impacting the equipment's performance.

[0003] To ensure effective water purification, reverse osmosis membrane filter cartridges need to be cleaned or replaced regularly. Currently, most existing technologies use threaded connections to secure the filter cartridges. Replacing the cartridge requires multiple rotations to remove the threads, which is not only time-consuming but also prone to problems like rust or jamming, making disassembly more difficult. This increases the workload and time cost for maintenance personnel and reduces equipment maintenance efficiency. Therefore, a reverse osmosis membrane device for greywater treatment is proposed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a reverse osmosis membrane device for treating greywater, so as to solve the problems of time-consuming and difficult operation when replacing reverse osmosis membrane filter elements by disassembling them by threads in the prior art, thereby improving the efficiency of filter element replacement and reducing maintenance costs.

[0005] The reverse osmosis membrane device for treating greywater provided in this application adopts the following technical solution:

[0006] A reverse osmosis membrane device for treating greywater includes a clean water tank, wherein a reverse osmosis membrane assembly is installed inside the clean water tank by a fixing mechanism.

[0007] The fixing mechanism includes two bidirectional lead screws rotatably connected to the inner walls of the upper and lower sides of the water tank. The two bidirectional lead screws are located on both sides of the reverse osmosis membrane assembly. Two screw blocks are symmetrically threaded to the outer walls of the bidirectional lead screws. The outer walls of the screw blocks are rotatably connected to connecting rods through bearing seats. An arc-shaped clamping plate is hinged to the end of each of the two connecting rods away from the screw blocks through the bearing seat. Rubber anti-slip pads are adhered to the outer walls of the two arc-shaped clamping plates facing each other. The two rubber anti-slip pads are tightly fitted to the outer walls of the reverse osmosis membrane assembly.

[0008] The outer wall of the water purification tank is equipped with a synchronous actuator, which drives two bidirectional lead screws to rotate synchronously.

[0009] Preferably, the synchronous actuator includes a driven wheel and a drive wheel. The top ends of two bidirectional lead screws pass through the water purification tank and are fixedly connected to the two driven wheels. The drive wheel is rotatably connected to the top outer wall of the water purification tank. A transmission belt is installed on the outer walls of both the drive wheel and the two driven wheels.

[0010] Preferably, the synchronous actuator further includes a servo motor fixedly installed on the inner wall of the top of the water purification tank, the output shaft of the servo motor passing through the water purification tank and fixedly connected to the shaft of the drive wheel.

[0011] Preferably, multiple telescopic columns are fixedly connected to the inner walls of both sides of the water purification tank, and the ends of the multiple telescopic columns away from the water purification tank are respectively fixedly connected to the outer walls of two arc-shaped clamps facing away from each other.

[0012] Preferably, the water tank has an inlet pipe on the top outer wall and an outlet pipe on the bottom outer wall. The bottom end of the inlet pipe is inserted into the top end of the reverse osmosis membrane assembly, and the bottom end of the reverse osmosis membrane assembly is inserted into the outlet pipe.

[0013] Preferably, the front outer wall of the water tank is hinged with an inspection door.

[0014] Preferably, a wastewater pipe is installed on the outer wall of the reverse osmosis membrane module, and an installation hole is provided on the outer wall of the water tank on the side away from the inspection door. The end of the wastewater pipe away from the reverse osmosis membrane module passes through the installation hole and extends out of the water tank.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] By cooperating with the set synchronous actuator and fixing mechanism, the two arc-shaped clamping plates can be driven to move relative to each other, thereby clamping and fixing the reverse osmosis membrane module. This allows for quick installation and fixing of the reverse osmosis membrane module. When replacing the reverse osmosis membrane module, simply drive the two arc-shaped clamping plates to move in opposite directions to release the clamping of the reverse osmosis membrane module, and the reverse osmosis membrane module can be quickly disassembled. Unlike traditional threaded connections, there is no need for multiple rotations and disassemblies, which greatly saves the time of replacing the reverse osmosis membrane module and improves maintenance efficiency.

[0021] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0022] This application discloses a reverse osmosis membrane device for treating greywater. (Refer to...) Figure 1-3 A reverse osmosis membrane device for treating greywater includes a clean water tank 1, and a reverse osmosis membrane assembly 5 is installed inside the clean water tank 1 by a fixing mechanism.

[0023] The fixing mechanism includes two bidirectional screw rods 6 rotatably connected to the inner walls of the upper and lower sides of the water tank 1. The two bidirectional screw rods 6 are located on both sides of the reverse osmosis membrane assembly 5. Two screw blocks 7 are symmetrically threaded to the outer walls of the bidirectional screw rods 6. The outer walls of the screw blocks 7 are rotatably connected to connecting rods 8 through bearing seats. The ends of each pair of upper and lower connecting rods 8 away from the screw blocks 7 are hinged to arc-shaped clamping plates 9 through bearing seats. Rubber anti-slip pads 10 are adhered to the outer walls of the two arc-shaped clamping plates 9. The two rubber anti-slip pads 10 are tightly attached to the outer walls of the reverse osmosis membrane assembly 5.

[0024] The outer wall of the water tank 1 is equipped with a synchronous actuator to drive two bidirectional lead screws 6 to rotate synchronously.

[0025] The synchronous actuator includes a driven wheel 12 and a drive wheel 13. The top ends of two bidirectional lead screws 6 pass through the water purification tank 1 and are fixedly connected to the two driven wheels 12. The drive wheel 13 is rotatably connected to the top outer wall of the water purification tank 1. The drive wheel 13 and the outer walls of the two driven wheels 12 are fitted with transmission belts 14.

[0026] The synchronous actuator also includes a servo motor 15 fixedly installed on the inner wall of the top of the water tank 1. The output shaft of the servo motor 15 passes through the water tank 1 and is fixedly connected to the shaft of the drive wheel 13.

[0027] Multiple telescopic columns 11 are fixedly connected to the inner walls of both sides of the water purification tank 1. The ends of the multiple telescopic columns 11 away from the water purification tank 1 are respectively fixedly connected to the outer walls of two arc-shaped clamps 9 facing away from each other.

[0028] The top outer wall of the water purification tank 1 is provided with an inlet pipe 2, and the bottom outer wall of the water purification tank 1 is provided with an outlet pipe 3. The bottom end of the inlet pipe 2 is inserted into the top end of the reverse osmosis membrane module 5, and the bottom end of the reverse osmosis membrane module 5 is inserted into the inside of the outlet pipe 3.

[0029] The front outer wall of the water tank 1 is hinged with an inspection door 4.

[0030] Wastewater pipe 16 is installed on the outer wall of reverse osmosis membrane module 5. A mounting hole 17 is provided on the outer wall of the water tank 1 away from the inspection door 4. The end of wastewater pipe 16 away from reverse osmosis membrane module 5 passes through the mounting hole 17 and extends out of the outside of water tank 1.

[0031] The implementation principle of a reverse osmosis membrane device for water treatment in this application embodiment is as follows: During installation, first open the inspection door 4, place the reverse osmosis membrane module 5 into the clean water tank 1, insert its bottom end into the inlet and outlet water pipes 3, and then insert its top end into the bottom end of the inlet water pipe 2. Through the cooperation of the synchronous actuator and the fixing mechanism, the servo motor 15 is started. The output shaft of the servo motor 15 drives the drive wheel 13 to rotate. The drive wheel 13 synchronously drives two driven wheels 12 to rotate in the same direction through two transmission belts 14. The two driven wheels 12 drive two bidirectional lead screws 6 to rotate. At this time, the bidirectional lead screws 6 rotate. The lead screw 6 rotates on the inner surface of the two screw blocks 7. Since the threads on the outer wall of the bidirectional lead screw 6 are symmetrically and oppositely arranged, a single bidirectional lead screw 6 can drive the two screw blocks 7 to move relative to each other. When the two screw blocks 7 move relative to each other, they will push the arc-shaped clamping plate 9 closer to the reverse osmosis membrane assembly 5 through the two inclined connecting rods 8. The two arc-shaped clamping plates 9 will then clamp the reverse osmosis membrane assembly 5 until the rubber anti-slip pad 10 is tightly attached to the outer wall of the reverse osmosis membrane assembly 5, which can prevent the reverse osmosis membrane assembly 5 from sliding, stably clamp and fix the reverse osmosis membrane assembly 5, and complete the installation of the reverse osmosis membrane assembly 5.

[0032] When replacing the reverse osmosis membrane module 5, open the inspection door 4. Similarly, start the servo motor 15 in reverse to make the two driven wheels 12 rotate in opposite directions. At this time, the two screw blocks 7 move away from each other, which pulls the arc-shaped clamping plate 9 outward through the connecting rod 8. The two arc-shaped clamping plates 9 move in opposite directions and release the clamping on the reverse osmosis membrane module 5, so that the reverse osmosis membrane module 5 can be quickly disassembled without having to rotate and disassemble it multiple times as required by traditional threaded connections. This greatly saves the time for replacing the reverse osmosis membrane module 5 and improves maintenance efficiency.
