Description

Technical Field

[0001] This utility model relates to the field of reverse osmosis membrane filtration technology, specifically a reverse osmosis vibrating membrane separation device. Background Technology

[0002] Reverse osmosis technology, as a core branch of pressure-driven membrane separation technology, is widely used in seawater desalination, industrial ultrapure water production, municipal drinking water advanced treatment, zero discharge of high-salinity wastewater, and material concentration due to its core advantages of extremely small pore size and high rejection rate of ions and small-molecule organic matter. Its core value lies in achieving highly efficient separation of solvents from almost all solutes, making it one of the core unit technologies with the highest desalination efficiency and the widest applicability.

[0003] Existing devices primarily filter wastewater by assembling reverse osmosis membranes inside filter cartridges. Many existing technologies resemble reverse osmosis membrane treatment equipment. The structure of CN219449420U includes a filter box: multiple reverse osmosis membranes are located at the bottom of the filter box; a sealing cover is fixedly connected to the inner top wall of the filter box; a threaded opening is formed on the upper surface of the filter box; a filter cartridge is threadedly connected to the inner wall of the threaded opening; a filter screen is fixedly embedded on the outer surface of the filter cartridge; a water pump is fixedly connected to the bottom surface of the sealing cover; the inlet of the water pump passes through the filter cartridge and extends into the interior of the sealing cover; the drain pipe of the water pump is fixedly connected to a water supply pipe; and equidistant connecting pipes are fixedly connected to the outer surface of the water supply pipe. This reverse osmosis membrane treatment equipment allows for easy disassembly, cleaning, and replacement of the filter cartridges and filter screens, improving the speed of cleaning and replacing the filter components. However, there are still areas for optimization in this device.

[0004] Existing devices mainly use detachable filter structures, which require frequent replacement and cleaning of the reverse osmosis membrane components in the filter cartridges. This makes it difficult for the fouling layer on the reverse osmosis membrane to be automatically peeled off by high-frequency oscillation, thus making it inconvenient to automatically clean the reverse osmosis membrane in the filter cartridges, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a reverse osmosis vibrating membrane separation device is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-5 One embodiment provided by this utility model: A reverse osmosis vibrating membrane separation device includes a base 11, a filter cartridge 12 rotatably mounted on the upper inner wall of the base 11, a transmission box 13 fixedly mounted on the top left side of the base 11, a swing separation mechanism 2 provided inside the transmission box 13, a controller 14 fixedly mounted on the top of the transmission box 13, an inlet pipe 15 fixedly connected to the middle of the bottom of the filter cartridge 12, a sewage pipe 16 fixedly connected to the front side of the bottom of the filter cartridge 12, and a clean water pipe 17 fixedly connected to the rear side of the bottom of the filter cartridge 12.

[0017] The filter cartridge 12 has layers of reverse osmosis membranes 18 stacked inside. Fastening screws 19 pass through the inner outer ring of the filter cartridge 12, arranged in a ring array. The inner outer ring of the reverse osmosis membranes 18 has through holes corresponding to the fastening screws 19. This design allows for the tight stacking of multiple layers of reverse osmosis membranes 18 inside the filter cartridge 12, ensuring that the flow channels of the multiple layers of reverse osmosis membranes 18 correspond one-to-one, effectively preventing wastewater from overflowing along the gaps between the reverse osmosis membranes 18.

[0018] The swing separation mechanism 2 includes a drive motor 21, the top of which is fixedly mounted on the top left side of the transmission housing 13. A drive shaft 22 is fixedly connected to the middle of the top of the drive motor 21. The top end of the drive shaft 22 passes through the front side wall of the transmission housing 13 and is fixedly connected to a crankshaft 23. The top central shaft of the crankshaft 23 is rotatably mounted above the inner wall of the transmission housing 13. This design enables the drive motor 21 to drive the drive shaft 22 and the crankshaft 23 to rotate in a limited position.

[0019] A connecting rod 24 is rotatably sleeved in the middle of the outer wall of the crankshaft 23. A push-pull rod 25 is movably connected to the right end of the connecting rod 24. The right end of the push-pull rod 25 passes through the left side plate of the base 11 and is movably connected to the lower left side of the filter cartridge 12. Through this design, the crankshaft 23 drives the push-pull rod 25 to reciprocate left and right through the connecting rod 24, so that the push-pull rod 25 drives the filter cartridge 12 to oscillate at high frequency.

[0020] Telescopic rods 26 are movably connected to the front and rear sides of the top of the base 11. A mounting plate 27 is movably connected to the top of the inner rod of the telescopic rod 26. The inner side of the mounting plate 27 is fixedly installed above the outer wall of the filter cartridge 12. Through this design, the filter cartridge 12 drives the mounting plate 27 to swing, thereby causing the telescopic rod 26 to extend or retract.

[0021] A spring 28 is fixedly sleeved on the lower outer wall of the outer cylinder of the telescopic rod 26, and the top end of the spring 28 is fixedly connected to the upper outer wall of the inner rod of the telescopic rod 26. Through this design, the spring 28 can automatically reset by pulling the telescopic rod 26 to assist the filter cartridge 12.

[0022] Working principle: When it is necessary to perform vibration separation of the fouling layer on the reverse osmosis membrane 18, the drive motor 21 is first started by the controller 14. The drive motor 21 drives the drive shaft 22 to rotate in a limited position. The drive shaft 22 drives the crankshaft 23 to rotate synchronously. The crankshaft 23 drives the left end of the connecting rod 24 to rotate synchronously, so that the right end of the connecting rod 24 drives the push-pull rod 25 to move back and forth. The push-pull rod 25 drives the filter cartridge 12 to swing at high frequency. The filter cartridge 12 drives the multi-layer reverse osmosis membrane 18 to swing synchronously, thus realizing the vibration separation operation of the fouling layer on the reverse osmosis membrane 18.
