[0002] In the fields of wastewater treatment and water resource reuse, MBR membranes, also known as membrane bioreactors, are a new type of water treatment technology that combines membrane separation units with biological treatment units.

[0003] MBR membrane technology is an advanced treatment unit for domestic wastewater in mining areas. Because domestic wastewater treatment systems lack grit chambers, subsequent processes operate under high pressure, making MBR membranes highly susceptible to clogging, reducing their filtration capacity, and affecting effluent quality. Furthermore, the high cost of membrane modules necessitates proper use, cleaning, and maintenance to prevent membrane fouling and extend their lifespan.

[0004] In existing technologies, conventional MBR membrane cleaning is mostly done manually by hand-held spray guns. Manual cleaning is time-consuming and labor-intensive. The dirt on the MBR membrane is often stubborn and cannot be guaranteed to be completely removed. The impurities remain attached for a long time, affecting the quality of the effluent and resulting in poor performance. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figures 1-5This utility model discloses an MBR membrane cleaning device, including a base box 1. The upper surface of the base box 1 is open. A grid plate 2 is fixedly installed on the inner wall of the base box 1 near the upper side. A rectangular cover 3 is fixedly installed on the upper surface of the base box 1, and both the front and rear sides of the rectangular cover 3 are open. An electric telescopic rod 4 is fixedly installed on the upper surface of the rectangular cover 3 near the front and rear positions. A clamping mechanism 5 is installed on the lower surface of the electric telescopic rod 4 and the upper surface of the grid plate 2. A vibration motor 6 is installed on the upper surface of the upper clamping mechanism 5 near the front and rear positions. The upper and lower clamping mechanisms 5 are arranged in a mirror image. The upper side wall of the rectangular cover 3 and the upper surface of the grid plate 2 are both equipped with moving mechanisms 7 near the left and right positions. The upper surface of the left moving mechanism 7 is connected to the output shaft of the drive motor 8. The drive motor 8 is installed on the upper surface of the rectangular cover 3. The left and right moving mechanisms 7 are connected by a transmission mechanism 9. The sides of the moving mechanisms 7 facing each other are equipped with spraying mechanisms 10. The spraying mechanisms 10 are connected to the water filter 12 through the extraction mechanism 11. The water filter 12 is embedded in the left side wall of the bottom box 1.

[0025] Specifically, the clamping mechanism 5 includes a first mounting plate 501, a spring damping shock absorber 502, a second mounting plate 503, and a clamping plate 504. The first mounting plate 501 is installed between the lower surfaces of the electric telescopic rod 4. Spring damping shock absorbers 502 are installed at the four corners of the lower surface of the first mounting plate 501. The second mounting plate 503 is fixedly installed between the lower surfaces of the spring damping shock absorbers 502. The second mounting plate 503 is used for mounting the vibration motor 6. Clamping plates 504 are installed on the lower surface of the second mounting plate 503 near the left and right positions.

[0026] In this embodiment, the first mounting plate 501 drives the second mounting plate 503 to move up and down through the spring damping shock absorber 502, which in turn drives the clamping plate 504 to move up and down, thereby adjusting the distance between the upper and lower clamping mechanisms 5, facilitating the insertion of MBR membranes of different specifications, and the spring damping shock absorber 502 meets the vibration requirements of the second mounting plate 503.

[0027] Specifically, the moving mechanism 7 includes a ball screw 701, a bearing assembly 702, and a ball nut 703. The upper and lower ends of the ball screw 701 are mounted on the upper surface of the grid plate 2 and the upper side wall of the rectangular cover 3 through the bearing assembly 702, and the upper surface of the ball screw 701 is fixed to the output shaft of the drive motor 8. The ball screw 701 is provided with a ball nut 703.

[0028] In this embodiment, the ball screw 701 rotates in the bearing assembly 702 driven by the drive motor 8. The rotation of the ball screw 701 causes the ball nut 703 to move up and down, which in turn causes the spraying mechanism 10 to move up and down. The ball screw 701 is a bidirectional screw.

[0029] Specifically, the outer surface of the ball nut 703 has a rectangular structure, and the ball nut 703 is movably fitted to the inner wall of the rectangular cover 3.

[0030] In this embodiment, the ball nut 703 moves stably up and down along the inner wall of the rectangular cover 3.

[0031] Specifically, the transmission mechanism 9 includes a transmission wheel 901 and a synchronous belt 902. The transmission wheel 901 is respectively mounted on the left and right ball screws 701, and the left and right transmission wheels 901 are connected by the synchronous belt 902.

[0032] In this embodiment, the left transmission wheel 901 rotates with the left ball screw 701, causing the left transmission wheel 901 to drive the right transmission wheel 901 to rotate via the synchronous belt 902, and the right transmission wheel 901 drives the right moving mechanism 7 to run.

[0033] Specifically, the spraying mechanism 10 includes a liquid distribution pipe 101 and a nozzle 102. The liquid distribution pipe 101 is installed on the side of the ball nut 703, and the nozzle 102 is installed on the liquid distribution pipe 101 at a uniform angle from front to back.

[0034] In this embodiment, water is sprayed from the nozzle 102 on the liquid distribution pipe 101 to clean the MBR membrane.

[0035] Specifically, the extraction mechanism 11 includes an extraction component 111, a conduit 112, a hose 113, and a three-way valve 114. The extraction component 111 is installed on the left side of the bottom box 1. The conduit 112 is installed on the outlet of the extraction component 111. The conduit 112 is connected to the liquid distribution pipe 101 through the hose 113. The extraction component 111 is connected to the water filter 12 through the three-way valve 114.

[0036] In this embodiment, the extraction component 111 can be connected to an external water pipe via a three-way valve 114, or it can be connected to a water filter 12, so that the extraction component 111 draws water into the conduit 112, and then flows into the left and right hoses 113 through the conduit 112, and then into the liquid distribution pipe 101 through the left and right hoses 113. The hoses 113 can move up and down with the liquid distribution pipe 101.

[0037] Specifically, a slag discharge valve 13 is fixedly installed on the lower edge of the right side wall of the bottom box 1.

[0038] In this embodiment, the slag discharge valve 13 facilitates the discharge of impurities from the bottom box 1.

[0039] During use, based on the height of the MBR membrane, the front and rear electric telescopic rods 4 drive the upper clamping mechanism 5 downwards, adjusting the distance between the upper and lower clamping mechanisms 5 so that the upper and lower ends of the MBR membrane are inserted along the upper clamping plate 504 of the second mounting plate 503, achieving the effect of fixing the MBR membrane. Then, the extraction component 111 in the extraction mechanism 11 can be connected to an external water pipe or a water filter 12 through the three-way valve 114, allowing the extraction component 111 to draw water into the conduit 112, which then flows into the left and right hoses 113, and then into the distribution pipe 101 in the spraying mechanism 10. The water is sprayed out through the nozzle 102 on the distribution pipe 101 to spray and clean the MBR membrane. Meanwhile, the output shaft of the drive motor 8 drives the ball screw 701 in the left moving mechanism 7 to rotate, and the left ball screw 701 is driven by the left transmission mechanism 9. Wheel 901 rotates with the left ball screw 701, causing the left drive wheel 901 to drive the right drive wheel 901 to rotate via the synchronous belt 902. The right drive wheel 901 drives the right moving mechanism 7 to run. The rotation of the ball screw 701 causes the ball nut 703 to move up and down, causing the ball nut 703 to drive the liquid distribution pipe 101 and the nozzle 102 to move up and down, which can more comprehensively clean the left and right sides of the MBR membrane. During the cleaning process, the vibration motor 6 drives the upper second mounting plate 503 to vibrate, and the second mounting plate 503 drives the MBR membrane to vibrate, making it easier for the deposits on the MBR membrane to fall off. It achieves high-pressure water cleaning, automatic folding cleaning, and can set the number of cleaning times, which significantly improves the cleaning efficiency and quality. The wastewater after cleaning flows into the bottom tank 1 through the mesh plate 2 and is easily treated through the slag discharge valve 13. The clean water automatically flows into the drainage system or is filtered and recycled.

[0040] In summary, this MBR membrane cleaning device utilizes high-pressure water cleaning, automatic folding and reversing cleaning, and allows for setting the number of cleaning cycles, significantly improving cleaning efficiency and quality. The cleaned waste is easier to handle, and the clean water automatically flows into the drainage system or is filtered and recycled. Furthermore, the addition of a vibration function enhances the cleaning effect.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
