Description

Technical Field

[0001] This utility model relates to the field of reverse osmosis filtration technology, specifically to a concentrated water reverse osmosis membrane circulation cleaning device. Background Technology

[0002] Reverse osmosis membrane filtration technology is a pressure-driven process that uses a semi-permeable membrane to efficiently separate solvents and solutes in a solution. Its technical principle is based on the "selective permeation" mechanism: under an applied pressure higher than the osmotic pressure of the solution, water molecules can pass through a dense separation layer, while dissolved salts, organic macromolecules, colloidal particles, and other solutes are selectively retained. The core of this process lies in the membrane material—usually a polyamide composite membrane—which has an active separation layer with nanoscale pores on its surface, enabling molecular-level sieving. The development of reverse osmosis technology began in the mid-20th century. With continuous breakthroughs in membrane material science, interfacial polymerization technology, and system integration processes, it has achieved significant progress in desalination rate, water flux, fouling resistance, and operational stability, and has now become one of the most refined membrane separation technologies.

[0003] With its superior separation performance, reverse osmosis technology plays an irreplaceable role in several key fields. Its earliest and most widespread application is in seawater and brackish water desalination, providing a core technological solution to the global water shortage problem. In the industrial sector, reverse osmosis membranes are widely used in the production of pure and ultrapure water, providing essential high-quality water for industries such as electronics, power, and pharmaceuticals. Simultaneously, it is also a core process for the deep treatment and reuse of industrial wastewater, effectively removing pollutants such as heavy metals and recalcitrant organic matter, achieving water resource recycling. Furthermore, reverse osmosis technology is increasingly prevalent in scenarios such as food and beverage concentration, municipal drinking water purification, and even household water purifiers. Its core advantages lie in its lack of phase change, relatively low energy consumption, ease of operation, and environmental friendliness, making it a key technological means to achieve sustainable water resource management and pollutant reduction.

[0004] During long-term operation, reverse osmosis membrane systems inevitably suffer from fouling on the surface of their membrane tubes, posing a key technical challenge to their stable operation and lifespan. Fouling primarily originates from microorganisms, colloids, particulate matter, and sparingly soluble salts in the feed water. These deposit and proliferate on the membrane surface, forming scale, biofilm, or gel layers. This fouling layer significantly increases system operating resistance and pressure, leading to decreased permeate flow, reduced desalination rate, and a sharp increase in energy consumption. Therefore, a cleaning device capable of effectively cleaning reverse osmosis membrane tubes is needed to enable the recycling of the membrane tubes and improve their operating efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a concentrated water reverse osmosis membrane circulation cleaning device.

[0006] The technical solution of this utility model is: a concentrated water reverse osmosis membrane circulation cleaning device, including a cleaning chamber, a support frame fixedly connected to the lower part of the cleaning chamber, a sealing door provided on the front side of the cleaning chamber, an upper snap-fit ​​component fixedly connected to the upper part of the interior of the cleaning chamber, a lower snap-fit ​​component fixedly connected to the inner bottom of the cleaning chamber, multiple cleaning nozzles fixed on the inner walls of both sides of the cleaning chamber, a water supply pipe connected to the outer end of the cleaning nozzles through a short water pipe, a water pump connected to the end of the water supply pipe, a water inlet pipe fixedly connected to the inlet of the water pump for connecting to an external water source, a drain pipe connected to the bottom of the cleaning chamber, and a PLC controller electrically connected to the water pump for controlling the start of the water pump.

[0007] Furthermore, the upper snap-fit ​​component includes an upper rotating disk rotatably connected to the top of the cleaning chamber. A snap-fit ​​groove for snapping the reverse osmosis membrane is provided below the upper rotating disk. A rotating servo motor for driving the upper rotating disk to rotate is fixed on the top of the cleaning chamber. The rotating servo motor is electrically connected to the PLC controller.

[0008] Explanation: By rotating the servo motor, the upper rotating disk rotates, which in turn drives the reverse osmosis membrane tube to rotate, so that the cleaning nozzle can clean the outer wall of the reverse osmosis membrane tube without dead angles.

[0009] Furthermore, the upper rotating disk is provided with an air-filling channel communicating with the interior of the reverse osmosis membrane, the top of the upper rotating disk is connected to an air-filling pipe, the end of the air-filling pipe is connected to an air-filling pump, the air-filling pump is electrically connected to the PLC controller, and the top of the cleaning chamber is provided with an exhaust pipe communicating with the interior and outer wall of the cleaning chamber.

[0010] Explanation: By supplying air to the inside of the reverse osmosis membrane tube through an air pump, pollutants attached to the pores of the reverse osmosis membrane tube are flushed out by the gas, clearing the pores of the reverse osmosis membrane tube, increasing the water flux of the reverse osmosis membrane tube, and thus improving the filtration efficiency of the reverse osmosis membrane tube.

[0011] Furthermore, the lower clamping component includes a fixed base fixed to the bottom of the cleaning chamber, a lower rotating disk rotatably connected above the fixed base, and a telescopic groove for clamping the lower end of the reverse osmosis membrane is movably clamped above the lower rotating disk, with an elastic spring provided between the telescopic groove and the upper surface of the rotating disk.

[0012] Instructions: When installing the reverse osmosis membrane tube, press the expansion groove downwards, then align the lower end of the reverse osmosis membrane tube with the center of the expansion groove. After releasing the expansion groove, under the action of the elastic spring, the expansion groove moves upwards and engages with the lower end of the reverse osmosis membrane tube.

[0013] Furthermore, the water pump is fixedly installed on the outer wall of the cleaning chamber, and a protective shell is fixedly connected to the outside of the cleaning chamber. The short water pipe, water supply pipe, and water pump are located between the outer wall of the cleaning chamber and the protective shell, and the PLC controller is fixedly connected to the outer wall of the protective shell.

[0014] Note: The protective casing protects the short water pipe, water supply pipe, and water pump from damage caused by external impacts.

[0015] The beneficial effects of this utility model are: This invention uses a rotating servo motor to drive the upper rotating disk to rotate, allowing the cleaning nozzles on both sides of the cleaning chamber to perform 360-degree cleaning of the outer wall of the reverse osmosis membrane tube without dead angles. By filling the reverse osmosis membrane tube with air, the pollutants clogging the pores of the reverse osmosis membrane tube are discharged. This invention's dual cleaning method can effectively improve the cleaning effect of the reverse osmosis membrane tube, thereby improving the reverse osmosis efficiency of the reverse osmosis membrane tube.

[0023] like Figure 4 , Figure 5 As shown, the upper clamping component 3 includes an upper rotating disk 31 that is rotatably connected to the top of the cleaning chamber 1. The lower part of the upper rotating disk 31 is provided with a clamping groove 32 for clamping the reverse osmosis membrane. The top of the cleaning chamber 1 is fixed with a rotating servo motor 33 for driving the upper rotating disk 31 to rotate. The rotating servo motor 33 is electrically connected to the PLC controller 6.

[0024] By rotating the servo motor 33, the upper rotating disk 31 is driven to rotate, which in turn drives the reverse osmosis membrane tube to rotate, so that the cleaning nozzle 5 can clean the outer wall of the reverse osmosis membrane tube without dead angles.

[0025] like Figure 3 As shown, the lower clamping component 4 includes a fixed base 41 fixed to the bottom of the cleaning chamber 1. A lower rotating disk 42 is rotatably connected above the fixed base 41. A telescopic groove 43 for clamping the lower end of the reverse osmosis membrane is movably clamped above the lower rotating disk 42. A spring spring 44 is provided between the telescopic groove 43 and the upper surface of the rotating disk.

[0026] When installing the reverse osmosis membrane tube, press the expansion groove 43 downwards, then align the lower end of the reverse osmosis membrane tube with the center of the expansion groove 43. After releasing the expansion groove 43, under the action of the elastic spring 44, the expansion groove 43 moves upwards and engages with the lower end of the reverse osmosis membrane tube.

[0027] Example 2: The difference between this embodiment and embodiment 1 is that, in this embodiment, as Figure 2 As shown, the upper rotating disk 31 is provided with an air-filling channel 34 that communicates with the interior of the reverse osmosis membrane. The top of the upper rotating disk 31 is connected to an air-filling pipe 35, and the end of the air-filling pipe 35 is connected to an air-filling pump 36. The air-filling pump 36 is electrically connected to the PLC controller 6. The top of the cleaning chamber 1 is provided with an exhaust pipe 13 that communicates with the interior and outer wall of the cleaning chamber 1.

[0028] Compared to Example 1, in this embodiment, the air pump 35 supplies air to the inside of the reverse osmosis membrane tube, causing the pollutants attached to the pores of the reverse osmosis membrane tube to be flushed out by the gas, thus clearing the pores of the reverse osmosis membrane tube, increasing the water flux of the reverse osmosis membrane tube, and thereby improving the filtration efficiency of the reverse osmosis membrane tube.

[0029] Example 3: The difference between this embodiment and embodiment 2 is that in this embodiment, the water pump 53 is fixedly installed on the outer wall of the cleaning chamber 1, and a protective shell 7 is fixedly connected to the outside of the cleaning chamber 1. The short water pipe 51, the water supply pipe 52, and the water pump 53 are located between the outer wall of the cleaning chamber 1 and the protective shell 7. The PLC controller 6 is fixedly connected to the outer wall of the protective shell 7.

[0030] Compared to Embodiment 2, this embodiment provides protection for the short water pipe 51, water supply pipe 52, and water pump 53 through the protective outer shell 7, preventing damage caused by external impact.

[0031] The working method of the above embodiment 3 includes the following steps: S1. After opening the sealing door 11, press the telescopic groove 43 downwards, then align the lower end of the reverse osmosis membrane tube with the center of the telescopic groove 43. After releasing the telescopic groove 43, under the action of the elastic spring 44, the telescopic groove 43 moves upwards and engages with the lower end of the reverse osmosis membrane tube, thus closing the sealing door. S2. The water pump 53 is started by the PLC controller 6. The cleaning nozzle washes the outer wall of the reverse osmosis membrane tube. The wastewater generated by the washing is discharged through the drain pipe 12. At the same time, the rotating servo motor 33 is started. The rotating servo motor 33 drives the upper rotating plate 31 to rotate, which in turn drives the reverse osmosis membrane tube to rotate, so that the cleaning nozzle 5 washes the outer wall of the reverse osmosis membrane tube without dead angles. S3. The air pump 35 is started by the PLC controller 6. The air pump 35 sends high-pressure air through the air channel 34 to the inside of the reverse osmosis membrane tube, so that the pollutants attached to the pores of the reverse osmosis membrane tube are flushed out by the gas, clearing the pores of the reverse osmosis membrane tube, increasing the water flux of the reverse osmosis membrane tube, and thus improving the filtration efficiency of the reverse osmosis membrane tube.

[0032] In the above embodiments, the side wing water pump 53, PLC controller 6, rotating servo motor 33, and air pump 36 are all commercially available products. As long as they can achieve the functions of this utility model, they are acceptable. Those skilled in the art can choose to use them based on common sense, and no special limitations are made here.
