Description

Technical Field

[0001] The present invention relates to the technical field of reverse osmosis filtration equipment, and specifically relates to a reverse osmosis membrane filter element assembly and a using method thereof. Background Art

[0002] At present, with the prominent problems of water resource pollution and shortage, and the surging demand for high-quality water in life and industry, traditional water treatment technologies such as sedimentation, filtration, and adsorption are difficult to meet the complex water quality purification requirements due to their limited ability to remove dissolved impurities, fine particles, and ionic substances.

[0003] Among them, when the reverse osmosis membrane filter element assembly is in use, large-particle impurities may exist in the water quality to be filtered and collide with the reverse osmosis membrane, resulting in damage to the reverse osmosis membrane, affecting the filtration effect and reducing the filtration effect. For the above problems, the following several solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a reverse osmosis membrane filter element assembly, which includes two annular plates. A hollow cylinder is rotatably connected between the two annular plates. A motor is fixedly connected to the top of the upper annular plate. A first rotating shaft is rotatably connected between the two annular plates, and the top of the first rotating shaft rotatably penetrates through the upper annular plate;

[0005] A filtering mechanism, the filtering mechanism includes a second filter screen, a fixing plate for restricting the position of the second filter screen, a sliding groove, a spring, a first filter screen, and a uniform feeding assembly for uniformly feeding materials;

[0006] The top and bottom of the first filter screen are fixedly connected to the inner wall of the hollow cylinder. The top and bottom outer walls of the fixing plate are fixedly connected to the inner wall of the hollow cylinder. The sliding grooves are respectively opened on the inner walls of the bottom and top of the hollow cylinder. The top and bottom of the second filter screen are slidably connected to the inner walls of the two sliding grooves. One side of the spring away from the fixing plate is fixedly connected to the outer wall of the second filter screen. The motor drives the large gear to rotate through the small gear on the first rotating shaft. The large gear drives the hollow cylinder to rotate. When the hollow cylinder rotates, it drives the first filter screen and the fixing plate to rotate. The second filter screen slides in the sliding groove and squeezes the spring to generate an elastic force, so that the first filter screen and the second filter screen are misaligned, thereby reducing the size of the filter screen opening, blocking large particles in the water in the first filter screen, and achieving the filtering effect. When the hollow cylinder stops rotating, the second filter screen resets under the action of the elastic force of the spring, aligning the filter screen openings. Under the action of inertia, the particles in the filter openings will be thrown out. The filtered water flows into the next process through the water outlet, preventing impurities from flowing out from the filter openings and improving the filtering effect.

[0007] Preferably, the uniform feeding component includes a small fixed rod fixedly connected to the inner wall of the top of the hollow cylinder. A fixed frame is fixedly connected to the bottom of the small fixed rod. A rotating shaft two is fixedly connected to the center of the fixed frame. A dispersing blade is fixedly connected to the outer wall of the rotating shaft two. A cleaning component is fixedly connected to the upper part of the filter screen two. When water is added into the hollow cylinder through the water inlet, the hollow cylinder is in a rotating state. Thus, when the hollow cylinder rotates, the rotating shaft two is driven to rotate through the small fixed rod and the fixed frame. When the rotating shaft two rotates, the dispersing blade is driven to rotate. While water is added into the hollow cylinder through the water inlet, under the action of the rotating dispersing blade, the water is broken up, so that it uniformly contacts the inner wall of the filter screen one, improving the filtering effect, increasing the contact between the water and the filter port, improving the filtering effect, reducing the accumulation of large particle impurities in the water, preventing the device from shaking during filtration, improving the use of the device, and enhancing the filtering effect;

[0008] The output shaft of the motor is fixedly connected to the rotating shaft one through a coupling. A large gear is fixedly connected to the outer wall of the hollow cylinder. A small gear is fixedly connected to the outer wall of the rotating shaft one. A water inlet is communicated and arranged at the top of the hollow cylinder. A water outlet is communicated and arranged at the bottom of the hollow cylinder.

[0009] Preferably, the cleaning component includes a large fixed rod fixedly connected to the inner wall of the hollow cylinder. A reverse osmosis membrane is fixedly connected to the outer wall of the large fixed rod.

[0010] Preferably, the cleaning component further includes fixed rings one rotatably connected to the inner walls of the top and bottom of the hollow cylinder respectively. A sliding rod is fixedly connected between the two fixed rings one. A silica gel scraping plate is rotatably connected to the outer wall of the sliding rod.

[0011] Preferably, the cleaning component further includes a fixed ring two fixedly connected to the outer wall of the filter screen two. The side of the silica gel scraping plate away from the reverse osmosis membrane is rotatably connected to the fixed ring two. An impurity cleaning component is fixedly connected to the bottom of the lower annular plate. When the position of the filter screen two moves, the filter screen two drives the silica gel scraping plate to move through the fixed ring two. The silica gel scraping plate rotates with the sliding rod as a fulcrum, thereby scraping the inner wall of the reverse osmosis membrane and cleaning the impurities on the inner wall of the reverse osmosis membrane. When the filter screen two returns to its original position, the filter screen two drives the silica gel scraping plate to move through the fixed ring two again. The silica gel scraping plate rotates with the sliding rod as a fulcrum again, thereby cleaning the reverse osmosis membrane for the second time, preventing excessive impurities from existing on the inner wall of the reverse osmosis membrane, affecting the filtering effect, and maintaining the filtering effect of the reverse osmosis membrane.

[0012] Preferably, the impurity cleaning component includes a bracket fixedly connected to the bottom of the lower annular plate. A bidirectional threaded rod is fixedly connected to the top of the bracket. The top of the bidirectional threaded rod is rotatably connected to the fixed frame.

[0013] Preferably, the impurity cleaning component further includes two trapezoidal chutes formed on the inner wall of the first filter screen. A cleaning auger is slidably connected between the two trapezoidal chutes. The middle axis of the cleaning auger is threadedly connected to the outer wall of the bidirectional threaded rod. When the first filter screen rotates, it drives the cleaning auger to rotate. At the same time, under the action of the thread pattern of the bidirectional threaded rod, the cleaning auger moves upward on the inner wall of the first filter screen, so as to continue cleaning the impurities on the inner wall of the first filter screen.

[0014] Preferably, the impurity cleaning component further includes an impurity outlet one communicated with the bottom of the hollow cylinder. A circular plate one is rotatably connected to the bottom of the hollow cylinder. The circular plate one rotates through the bottom of the hollow cylinder and extends to the inside. A connecting arm is fixedly connected to the extended part of the circular plate one. The circular part of the connecting arm is rotatably connected to the outer wall of the bidirectional threaded rod. A spring telescopic rod is fixedly connected to the top of the connecting arm.

[0015] Preferably, the impurity cleaning component further includes an impurity outlet two communicated with the bottom of the hollow cylinder. A triangular plate is slidably connected to the bottom of the circular plate one. The bottom outer wall of the triangular plate is slidably connected to a circular plate two. A convex column is fixedly connected to the triangular plate. The top of the convex column is slidably connected to the arc groove of the circular plate one. The bottom of the convex column is slidably connected to the arc groove of the circular plate two. An arc spring is fixedly connected to the arc groove of the circular plate two. The arc spring is fixedly connected to the convex column. When the cleaning auger moves to the top of the bidirectional threaded rod, the cleaning auger will move downward along the other thread pattern of the bidirectional threaded rod. When the cleaning auger moves to the bottom, the cleaning auger drives the connecting arm and the circular plate one to rotate clockwise around the bidirectional threaded rod through the spring telescopic rod. As Figure 11 shown, the arc groove of the circular plate one pushes the triangular plate to slide along the arc groove of the circular plate two through the convex column. As Figure 12 shown, when the convex column moves, it squeezes the arc spring to generate an elastic force, so that multiple triangular plates open to form a dislocation and generate a gap, so that the impurities in the first filter screen and the reverse osmosis membrane are discharged from the impurity outlet one and the impurity outlet two through the gap. When the cleaning auger moves upward, the connecting arm stops rotating. Under the action of the elastic force of the arc spring, multiple triangular plates are reset, so as to close the impurity outlet one and the impurity outlet two, prevent the impurities in the first filter screen and the reverse osmosis membrane from accumulating too much, resulting in the blockage of the filter port, and improve the service life of the device.

[0016] A method for using a reverse osmosis membrane filter element assembly includes the following steps:

[0017] S1: Add dirty water: The water to be filtered enters the hollow cylinder through the water inlet.

[0018] S2: Start the device: Start the motor. The motor drives the large gear to rotate through the small gear on the first rotating shaft. The large gear drives the hollow cylinder to rotate. The filtered water flows into the next process through the water outlet.

[0019] The present invention has the following beneficial effects:

[0020] 1. When the present invention is in use, there may be large-particle impurities in the filtered water quality. The water to be filtered enters the hollow cylinder through the water inlet. Then, the motor is started. The small gear on the first rotating shaft drives the large gear to rotate, and the large gear drives the hollow cylinder to rotate. When the hollow cylinder rotates, it drives the first filter screen and the fixing plate to rotate. When the second filter screen slides in the chute, it squeezes the spring to generate elastic force, so that the first filter screen and the second filter screen are misaligned, thereby reducing the size of the filter screen opening, blocking large particles in the water in the first filter screen, achieving the filtering effect. When the hollow cylinder stops rotating, the second filter screen resets under the action of the spring elastic force, aligning the filter screen opening. Under the action of inertia, the particles in the filter opening will be thrown out. The filtered water flows into the next process through the water outlet, preventing impurities from flowing out through the filter opening and improving the filtering effect.

[0021] 2. The present invention utilizes the rotational force of the first filter screen. When adding water into the inner part of the hollow cylinder through the water inlet, the hollow cylinder is in a rotating state. Thus, while the hollow cylinder rotates, it drives the second rotating shaft to rotate through the small fixing rod and the fixing frame. When the second rotating shaft rotates, it drives the dispersing blades to rotate. While adding water into the inner part of the hollow cylinder through the water inlet, under the action of the rotating dispersing blades, the water is broken up, making it evenly contact the inner wall of the first filter screen, improving the filtering effect, increasing the contact between the water and the filter opening, improving the filtering effect, reducing the accumulation of large-particle impurities in the water, preventing the device from shaking during filtration, improving the use of the device, and enhancing the filtering effect.

[0022] 3. The present invention utilizes the moving force of the second filter screen. When the position of the second filter screen moves, the second filter screen drives the silica gel scraper to move through the second fixing ring. The silica gel scraper rotates with the sliding rod as the fulcrum, thereby scraping the inner wall of the reverse osmosis membrane and cleaning the impurities on the inner wall of the reverse osmosis membrane. When the second filter screen resets, the second filter screen drives the silica gel scraper to move through the second fixing ring again, and the silica gel scraper rotates with the sliding rod as the fulcrum again, thereby cleaning the reverse osmosis membrane for the second time, preventing excessive impurities from existing on the inner wall of the reverse osmosis membrane, affecting the filtering effect, and maintaining the filtering effect of the reverse osmosis membrane.

[0023] 4. The present invention utilizes the rotational force of the first filter screen. When the first filter screen rotates, it drives the cleaning auger to rotate. At the same time, under the action of the thread of the bidirectional threaded rod, the cleaning auger moves upward on the inner wall of the first filter screen, thereby continuously cleaning the impurities on the inner wall of the first filter screen. When the cleaning auger moves to the top of the bidirectional threaded rod, the cleaning auger will move downward along the other thread of the bidirectional threaded rod. When the cleaning auger moves to the bottom, the cleaning auger drives the connecting arm and the first circular plate to rotate clockwise with the bidirectional threaded rod as the rotation point through the spring telescopic rod, as Figure 11, the arc-shaped groove of the circular plate 1 pushes the triangular plate to slide in the arc-shaped groove of the circular plate 2, as Figure 12 , when the protruding column moves, it squeezes the arc-shaped spring to generate elastic force, so that multiple triangular plates open to form a dislocation to generate a gap, enabling the impurities in the filter screen 1 and the reverse osmosis membrane to be discharged from the impurity outlet 1 and the impurity outlet 2 through the gap. When the cleaning auger moves upward, the connecting arm stops rotating, and under the action of the elastic force of the arc-shaped spring, multiple triangular plates are reset, thereby closing the impurity outlet 1 and the impurity outlet 2 to prevent excessive accumulation of impurities in the filter screen 1 and the reverse osmosis membrane, resulting in blockage of the filtering port and improving the service life of the device.

[0044] The top and bottom of the first filter screen 21 are fixedly connected to the inner wall of the hollow cylinder 11. The top and bottom outer walls of the fixing plate 22 are fixedly connected to the inner wall of the hollow cylinder 11. The chutes 23 are respectively arranged on the inner walls of the bottom and top of the hollow cylinder 11. The top and bottom of the second filter screen 24 are slidably connected to the inner walls of the two chutes 23. One side of the spring 25 away from the fixing plate 22 is fixedly connected to the outer wall of the second filter screen 24. The motor 12 drives the large gear 14 to rotate through the small gear 15 on the first rotating shaft 13. The large gear 14 drives the hollow cylinder 11 to rotate. When the hollow cylinder 11 rotates, it drives the first filter screen 21 and the fixing plate 22 to rotate. The second filter screen 24 slides in the chute 23 to squeeze the spring 25 to generate elastic force, so that the first filter screen 21 and the second filter screen 24 are misaligned, thereby reducing the size of the filter opening, blocking large particles in the water in the first filter screen 21, and achieving the filtering effect. When the hollow cylinder 11 stops rotating, the second filter screen 24 resets under the elastic force of the spring 25 to align the filter openings. Under the action of inertia, the particles in the filter openings will be thrown out. The filtered water flows into the next process through the water outlet 17, preventing impurities from flowing out through the filter openings and improving the filtering effect.

[0045] Example two, please refer to Figure 5 - Figure 14 , the present invention is a reverse osmosis membrane filter element assembly. On the basis of Example 1, the uniform feeding component 3 includes a small fixed rod 31 fixedly connected to the inner wall of the top of the hollow cylinder 11.

The outer wall of the second rotating shaft 33 is fixedly connected to a dispersing blade 34. A cleaning component 4 is fixedly connected to the second filter screen 24. When water is added into the hollow cylinder 11 through the water inlet 16, the hollow cylinder 11 is in a rotating state. Thus, while the hollow cylinder 11 rotates, it drives the second rotating shaft 33 to rotate through the small fixed rod 31 and the fixed frame 32. When the second rotating shaft 33 rotates, it drives the dispersing blade 34 to rotate. While water is added into the hollow cylinder 11 through the water inlet 16, under the action of the rotation of the dispersing blade 34, the water is broken up, making it uniformly contact the inner wall of the first filter screen 21, improving the filtering effect, increasing the contact between the water and the filter openings, improving the filtering effect, reducing the accumulation of large particle impurities in the water, preventing the device from shaking during filtration, improving the use of the device, and enhancing the filtering effect;

[0049] The cleaning assembly 4 further includes a second fixed ring 46 fixedly connected to the outer wall of the second filter screen 24. The side of the silica gel scraping plate 45 away from the reverse osmosis membrane 42 is rotatably connected to the second fixed ring 46. An impurity cleaning assembly 5 is fixedly connected to the bottom of the lower annular plate 1. When the second filter screen 24 moves, the second filter screen 24 drives the silica gel scraping plate 45 to move through the second fixed ring 46. The silica gel scraping plate 45 rotates with the sliding rod 44 as a fulcrum, so as to scrape the inner wall of the reverse osmosis membrane 42 and clean the impurities on the inner wall of the reverse osmosis membrane 42. When the second filter screen 24 resets, the second filter screen 24 drives the silica gel scraping plate 45 to move through the second fixed ring 46 again. The silica gel scraping plate 45 rotates with the sliding rod 44 as a fulcrum again, so as to clean the reverse osmosis membrane 42 for the second time, prevent too many impurities from existing on the inner wall of the reverse osmosis membrane 42, affect the filtering effect, and maintain the filtering effect of the reverse osmosis membrane 42.

[0050] The impurity cleaning assembly 5 includes a bracket 51 fixedly connected to the bottom of the lower annular plate 1. A bidirectional threaded rod 52 is fixedly connected to the top of the bracket 51. The top of the bidirectional threaded rod 52 is rotatably connected to the fixed frame 32.

[0051] The impurity cleaning assembly 5 further includes two trapezoidal chutes 53 opened on the inner wall of the first filter screen 21. A cleaning auger 54 is slidably connected between the two trapezoidal chutes 53. The middle axis of the cleaning auger 54 is threadedly connected to the outer wall of the bidirectional threaded rod 52. When the first filter screen 21 rotates, it drives the cleaning auger 54 to rotate. At the same time, under the action of the thread of the bidirectional threaded rod 52, the cleaning auger 54 moves upward on the inner wall of the first filter screen 21, so as to continuously clean the impurities on the inner wall of the first filter screen 21.

[0052] The impurity cleaning component 5 further includes an impurity outlet 55 connected to the bottom of the hollow cylinder 11. A circular plate 56 is rotatably connected to the bottom of the hollow cylinder 11. The circular plate 56 rotates through the bottom of the hollow cylinder 11 and extends into the interior. A connecting arm 57 is fixedly connected to the extended part of the circular plate 56. The circular part of the connecting arm 57 is rotatably connected to the outer wall of the bidirectional threaded rod 52.

[0053] The impurity cleaning component 5 further includes an impurity outlet 59 connected to the bottom of the hollow cylinder 11. A triangular plate 510 is slidably connected to the bottom of the circular plate 56. A circular plate 511 is slidably connected to the bottom outer wall of the triangular plate 510. A protruding column 512 is fixedly connected to the triangular plate 510. The top of the protruding column 512 is slidably connected to the arc groove of the circular plate 56. The bottom of the protruding column 512 is slidably connected to the arc groove of the circular plate 511. An arc spring 513 is fixedly connected to the arc groove of the circular plate 511. The arc spring 513 is fixedly connected to the protruding column 512. When the cleaning auger 54 moves to the top of the bidirectional threaded rod 52, the cleaning auger 54 will move downward along the other thread of the bidirectional threaded rod 52. When the cleaning auger 54 moves to the bottom, the cleaning auger 54 drives the connecting arm 57 and the circular plate 56 to rotate clockwise around the bidirectional threaded rod 52 through the spring telescopic rod 58, as Figure 11 , the arc groove of the circular plate 56 pushes the triangular plate 510 to slide along the arc groove of the circular plate 511 through the protruding column 512, as Figure 12 , when the protruding column 512 moves, it squeezes the arc spring 513 to generate elastic force, so that multiple triangular plates 510 open to form a dislocation and generate a gap, so that the impurities in the filter screen 21 and the reverse osmosis membrane 42 are discharged from the impurity outlet 55 and the impurity outlet 59 through the gap. When the cleaning auger 54 moves upward, the connecting arm 57 stops rotating, and under the action of the elastic force of the arc spring 513, multiple triangular plates 510 are reset, so as to close the impurity outlet 55 and the impurity outlet 59, prevent the accumulation of too many impurities in the filter screen 21 and the reverse osmosis membrane 42, cause the filter port to be blocked, and improve the service life of the device.

[0054] The usage method of this reverse osmosis membrane filter element assembly includes the following steps:

[0055] S1: Add dirty water: The water to be filtered enters the hollow cylinder 11 through the water inlet 16;

[0056] S2: Start the device: Start the motor 12. The motor 12 drives the large gear 14 to rotate through the small gear 15 on the rotating shaft 13. The large gear 14 drives the hollow cylinder 11 to rotate. The filtered water flows into the next process through the water outlet 17.

[0057] A specific application of this embodiment is as follows: When in use, the water to be filtered enters the hollow cylinder 11 through the water inlet 16. Then, the motor 12 is started. The motor 12 drives the large gear 14 to rotate through the small gear 15 on the first rotating shaft 13. The large gear 14 drives the hollow cylinder 11 to rotate. When the hollow cylinder 11 rotates, it drives the first filter screen 21 and the fixed plate 22 to rotate. The second filter screen 24 slides in the chute 23 to squeeze the spring 25 to generate elastic force, so that the first filter screen 21 and the second filter screen 24 are misaligned, thereby reducing the size of the filter screen opening, blocking large particles in the water inside the first filter screen 21, and achieving the filtering effect. When the hollow cylinder 11 stops rotating, the second filter screen 24 resets under the action of the elastic force of the spring 25 to align the filter screen openings. Under the action of inertia, the particles in the filter openings will be thrown out. The filtered water flows into the next process through the water outlet 17, preventing impurities from flowing out through the filter openings and improving the filtering effect.

[0058] When adding water into the interior of the hollow cylinder 11 through the water inlet 16, the hollow cylinder 11 is in a rotating state. Thus, while the hollow cylinder 11 rotates, it drives the second rotating shaft 33 to rotate through the small fixing rod 31 and the fixing bracket 32. When the second rotating shaft 33 rotates, it drives the dispersing blades 34 to rotate. While adding water into the interior of the hollow cylinder 11 through the water inlet 16, under the action of the rotation of the dispersing blades 34, the water is dispersed, making it uniformly contact the inner wall of the first filter screen 21, improving the filtering effect, increasing the contact between the water and the filter openings, improving the filtering effect, reducing the accumulation of large particle impurities in the water, preventing the device from shaking during filtration, improving the use of the device, and enhancing the filtering effect.

[0059] Fine impurities will flow out through the filter openings and stick to the inner wall of the reverse osmosis membrane 42, resulting in an increase in the filtration time of the reverse osmosis membrane 42. When the position of the second filter screen 24 moves, the second filter screen 24 drives the silica gel scraper 45 to move through the second fixing ring 46. The silica gel scraper 45 rotates with the sliding rod 44 as the fulcrum, thereby scraping the inner wall of the reverse osmosis membrane 42 to clean the impurities on the inner wall of the reverse osmosis membrane 42. When the second filter screen 24 resets, the second filter screen 24 drives the silica gel scraper 45 to move through the second fixing ring 46 again. The silica gel scraper 45 rotates with the sliding rod 44 as the fulcrum again, thereby performing secondary cleaning on the reverse osmosis membrane 42, preventing excessive impurities from existing on the inner wall of the reverse osmosis membrane 42, affecting the filtering effect, and maintaining the filtering effect of the reverse osmosis membrane 42.

[0060] When the first filter screen 21 rotates, it drives the cleaning auger 54 to rotate. At the same time, under the action of the threads of the bidirectional threaded rod 52, the cleaning auger 54 moves upward on the inner wall of the first filter screen 21, so as to continue cleaning the impurities on the inner wall of the first filter screen 21. When the cleaning auger 54 moves to the top of the bidirectional threaded rod 52, the cleaning auger 54 will move downward along the other thread of the bidirectional threaded rod 52. When the cleaning auger 54 moves to the bottom, the cleaning auger 54 drives the connecting arm 57 and the first circular plate 56 to rotate clockwise around the bidirectional threaded rod 52 through the spring telescopic rod 58, as Figure 11 , the arc-shaped groove of the first circular plate 56 pushes the triangular plate 510 to slide along the arc-shaped groove of the second circular plate 511 through the protruding column 512, as Figure 12 , when the protruding column 512 moves, it squeezes the arc-shaped spring 513 to generate elastic force, so that a plurality of triangular plates 510 open to form a dislocation to generate a gap, so that the impurities in the first filter screen 21 and the reverse osmosis membrane 42 are discharged from the impurity outlet 55 and the impurity outlet 59 through the gap. When the cleaning auger 54 moves upward, the connecting arm 57 stops rotating. Under the action of the elastic force of the arc-shaped spring 513, a plurality of triangular plates 510 are reset, so as to close the impurity outlet 55 and the impurity outlet 59, prevent the impurities in the first filter screen 21 and the reverse osmosis membrane 42 from accumulating too much, resulting in the blockage of the filter port, and improve the service life of the device.
