[0002] As an advanced sewage treatment technology, membrane bioreactor combines the advantages of membrane technology and biological treatment and has been widely used in the field of sewage treatment. MABR technology forms a biofilm on the membrane surface and uses gas diffusion for aeration, allowing microorganisms to grow on the membrane surface and degrade organic matter, thereby achieving efficient sewage treatment. However, the existing MABR membrane components still have some shortcomings during use, which limits their treatment efficiency and flexibility.

[0003] First, the existing MABR membrane components are often complicated to maintain and replace, which requires a lot of time and manpower. This not only increases operating costs, but may also cause membrane damage or contamination due to improper operation.

[0024] It should be noted that the outer rings of the speed regulating component 31, the active component 32 and the vibration component 22 are all provided with waterproof shells to prevent sewage from corroding the internal electrical components.

[0025] In this embodiment, when sewage treatment is carried out, the entire device is placed in the sewage. At this time, through the control of the speed regulating component 31, the rotating part of the frame component 11 is connected to the different speed intervals driven by the active component 32, and the speed adjustment of the membrane component 12 can be realized to adapt to different sewage treatment needs. When the membrane component 12 rotates at the lowest speed, the cleaning part of the scratching component 21 will be driven to contact the outer ring of the membrane component 12 for effective cleaning to prevent the accumulation of dirt and microorganisms. At the same time, the vibration component 22 vibrates during the rotation of the membrane component 12, further improving the sewage treatment efficiency and aeration effect. The lifting part of the vibration component 22 contacts the treatment part of the membrane component 12 when the membrane component 12 rotates, and vibrates by squeezing the top of the vibration part, effectively reducing the adhesion and precipitation of microorganisms and impurities.

[0027] It should be noted that an inlet is provided at the top of the vent pipe 113 , and a filter (not shown in the figure) is provided in the exhaust port 114 to prevent garbage in the sewage from entering the exhaust port 114 .

[0028] In this embodiment, in normal sewage treatment, the vent pipe 113 receives oxygen from the outside and sends it to the exhaust port 114 and the membrane component 12 for effective aeration, thereby achieving sewage treatment. When the treatment membrane 122 needs to be replaced or maintained, the treatment membrane 122 can be dismantled and replaced by simply removing the mounting bolt 123, thereby facilitating the replacement and maintenance of the treatment membrane 122.

[0029] Secondly, please refer again to Figure 5 to Figure 6 , Figures 9 to 13 The scratch assembly 21 includes a rotating rod 211 rotatably connected to the inner cavity of the assembly tube 112, the outer ring of the rotating rod 211 is fixedly connected to a scraper 212, the scraper 212 is slidably connected to the middle part of the assembly tube 112, the top of the rotating rod 211 extends into the top inner cavity of the mounting frame 111 and is fixedly connected to a first gear 213, the top inner cavity of the mounting frame 111 is rotatably connected to a gear ring 214, the outer ring of the gear ring 214 is meshed with the outer ring of the first gear 213, the top inner ring of the gear ring 214 is rotatably connected to an electric push rod 215, and the rear end of the electric push rod 215 is rotatably connected to the left side of the inner cavity at the top of the mounting frame 111 through a rotating shaft; The speed regulating assembly 31 comprises a support frame 311 fixedly connected to the bottom of the mounting frame 111, a plurality of sleeves are arranged at the right end of the support frame 311, and a second gear 312 is rotatably connected in each sleeve, a hexagonal groove 313 is provided in the inner cavity of the second gear 312, a linkage rod 314 is slidably connected in the hexagonal groove 313, a linkage block 315 is fixedly connected to the top of the linkage rod 314, a linkage groove 316 is provided in the inner cavity of the bottom of the vent pipe 113, the linkage block 315 is slidably connected in the linkage groove 316, a lifting plate 317 is rotatably connected to the bottom of the linkage rod 314, a hydraulic rod 318 is fixedly connected to the bottom of the lifting plate 317, and the hydraulic rod 318 is installed below the mounting frame 111, and a press switch 319 is fixedly installed at the top of the inner cavity of the sleeve at the right end of the support frame 311; The active component 32 includes a second motor 321 fixedly mounted on the right side below the mounting frame 111, a driving shaft 322 is fixedly connected to the output shaft of the second motor 321, an outer ring of the driving shaft 322 is fixedly connected to a gear set 323, and the outer rings of the gear set 323 are meshed with the outer rings of the second gear 312; The second gears 312 are provided with four groups, and the diameters are arranged downward in descending order, while the gear set 323 is composed of four groups of gears arranged in descending order, and the outer rings of the gears on both sides are meshed.

[0030] It should be noted that the push switch 319 is a switch for driving the electric push rod 215 to operate, and the operation mode is that when the push switch 319 is pushed, the electric push rod 215 operates, and when it is released, it is reset.

[0031] In this embodiment, when sewage treatment is performed, the second motor 321 drives the drive shaft 322 and the gear set 323 to rotate. At this time, the gears of different diameters on the gear set 323 are respectively meshed with the second gears 312 of different diameters, so that the rotation speed of each second gear 312 is different. Before this, the hydraulic rod 318 will push the lifting plate 317 to move up and down, so that the linkage rod 314 and the linkage block 315 move up and down along the linkage groove 316. At this time, the linkage rod 314 is connected to the second gear 312 with different rotation speeds, and then drives the ventilation pipe 113 to rotate at different rotation speeds through the linkage block 315 and the linkage groove 316. In this way, the rotation speed of the treatment membrane 122 is finely controlled to adapt to different sewage treatment conditions. When the treatment membrane 122 runs at the lowest speed, the linkage rod 314 will touch the push switch 319. At this time, the electric push rod 215 receives the signal and starts to run, pushing the gear ring 214 to rotate. At this time, the gear ring 214 will drive the first gear 213 to rotate, and then drive the rotating rod 211 and the scraper 212 to rotate, so that the scraper 212 extends out of the assembly tube 112 and contacts the outer edge of the treatment membrane 122, so that the outer edge of the treatment membrane 122 at the lowest speed will continuously contact the scraper 212, thereby scraping off and cleaning the sediment and microorganisms adhering to the outer edge of the treatment membrane 122.

[0032] Secondly, please refer again to Figures 7 and 8 The vibration assembly 22 includes a lifting frame 221 slidably connected to the inner cavity of the assembly tube 112, a screw rod 222 is threadedly connected to the middle inner ring of the lifting frame 221, and the screw rod 222 is rotatably connected to the inner cavity of the assembly tube 112. A first motor 223 is fixedly connected to the right side of the bottom surface of the mounting frame 111, and the output shaft of the first motor 223 is fixedly connected to the bottom end of the screw rod 222. A lifting rod 224 is fixedly connected to the outer ring of the lifting frame 221, and the lifting rod 224 is slidably connected to the outer ring of the assembly tube 112. An extrusion block 225 is slidably connected to the top inner cavity of the lifting rod 224, and a spring 226 is fixedly connected to the bottom of the inner cavity of the extrusion block 225. The bottom of the extrusion block 225 is fixedly connected to the spring 226, and the bottom end of the spring 226 is fixedly connected to the bottom of the inner cavity of the lifting rod 224.

[0033] It should be noted that the outer ring of the assembly tube 112 is provided with a through slot, so that the lifting rod 224 can be raised and lowered to any height, thereby controlling whether the processing film 122 vibrates, or controlling the amplitude of the vibration; Both sides of the extrusion block 225 are provided with slopes, so that when the extrusion block 225 contacts the bracket 121 , it will be pushed downward by the bracket 121 so as to rebound and push the processing film 122 to vibrate.

[0034] In this embodiment, when sewage treatment is performed, the first motor 223 drives the screw rod 222 to rotate, thereby driving the lifting frame 221 to move up and down. When the extrusion block 225 contacts the bracket 121, the extrusion block 225 will be pushed downward by the bracket 121, and the spring 226 will be compressed accordingly. Due to the design of the slopes on both sides of the extrusion block 225, even when the bracket 121 is rotating, it can contact the extrusion block 225 through the slope and push the extrusion block 225 to move downward. When the extrusion block 225 is separated from the bracket 121, the spring 226 will release energy, pushing the extrusion block 225 to move upward and hit the treatment membrane 122, thereby applying vibration to the treatment membrane 122. In this way, the dirt and microorganisms on the surface of the treatment membrane 122 can be effectively removed, and the sewage treatment efficiency can be improved. In addition, the vibration frequency and amplitude of the vibration component 22 can be adjusted according to the actual sewage treatment needs to achieve the best cleaning effect.

[0035] The working principle of the present invention is as follows: when treating sewage, the second motor 321 drives the driving shaft 322 and the gear set 323 to rotate, and drives each second gear 312 to rotate at different speeds. Before this, the hydraulic rod 318 will push the lifting plate 317 and the linkage block 315 to move up and down. At this time, the linkage rod 314 is connected to the second gear 312 of different speeds, and then drives the vent pipe 113 and the treatment membrane 122 to rotate at different speeds through the linkage block 315 and the linkage groove 316 for aeration and sewage treatment. At this time, the vent pipe 113 sends oxygen received from the outside to the exhaust port 114 and the membrane component 12 for effective aeration, thereby achieving sewage treatment. When the treatment membrane 122 needs to vibrate, the first motor 223 drives the screw rod 222 to rotate, drives the lifting frame 221 and the extrusion block 225 to move upward, and compresses the spring 226. When the extrusion block 225 is separated from the bracket 121, the spring 226 will push the extrusion block 225 to hit the treatment membrane 122 to generate vibration. In this way, dirt and microorganisms on the surface of the treatment membrane 122 can be effectively removed, and the sewage treatment efficiency can be improved. When the treatment membrane 122 runs at the lowest speed, the linkage rod 314 will touch the push switch 319, and the electric push rod 215 will receive the signal and start running, pushing the gear ring 214 to rotate, driving the first gear 213 and the scraper 212 to rotate, so that the scraper 212 extends out of the assembly tube 112 and contacts the outer edge of the treatment membrane 122, thereby scraping off the sediment and microorganisms adhering to the outer edge of the treatment membrane 122.

[0036] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
