[0002] Cleaning the MBR flat membrane is a crucial step in the operation and maintenance of an MBR system. Currently, common cleaning methods are categorized into two main types: online cleaning and offline cleaning. Offline cleaning involves removing the membrane components from the MBR system for cleaning. This method is more thorough and can remove stubborn contaminants from the membrane surface.

[0003] Chinese utility model patent application number CN201822233405.6 discloses an MBR flat membrane cleaning device. This device uses clamps to secure the flat membrane to a carrier plate. A motor drives the carrier plate to rotate while a nozzle sprays cleaning fluid onto the flat membrane. This MBR flat membrane cleaning device requires shutdown to replace the membrane after each cleaning cycle, resulting in low cleaning efficiency.

[0004] Therefore, it is necessary to propose an MBR flat membrane automatic cleaning machine to solve the above problems. Utility Model Content

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] See also Figure 1-5 As shown, an MBR flat membrane automatic cleaning machine includes a bracket 2, on which a conveying channel is arranged along its horizontal direction, and the conveying channel is used to convey the MBR flat membrane 12. A conveying mechanism 5 is provided at the feed end of the conveying channel, and the conveying mechanism 5 includes a clamping belt 10. The clamping belts 10 driven by the driving mechanism are symmetrically arranged on both sides of the conveying channel; a flushing mechanism 3 and a scrubbing mechanism 4 are arranged in sequence along the feeding direction of the conveying channel, and the flushing mechanism 3 includes a flushing pipe 14. A plurality of flushing pipes 14 are provided on both sides of the conveying channel, and a spray head 13 is provided on the side of the flushing pipe 14 corresponding to the conveying channel; the scrubbing mechanism 4 includes a cleaning roller 15. A plurality of cleaning rollers 15 are symmetrically arranged on both sides of the conveying channel.

[0032] During use, the MBR flat membrane 12 is inserted into the feed end of the conveying channel. The pinch belts 10 on either side of the conveying channel clamp the MBR flat membrane 12, respectively. A drive mechanism rotates the pinch belts 10, pushing the MBR flat membrane 12 along the conveying channel. The front MBR flat membrane 12 is pushed by the rear MBR flat membrane 12. When the MBR flat membrane 12 moves to the flushing mechanism 3, multiple spray heads 13 flush it from both sides. When the MBR flat membrane 12 moves to the scrubbing mechanism 4, multiple cleaning rollers 15 scrub the MBR flat membrane 12, thereby automatically completing the cleaning process. By flushing first and then scrubbing, the flushing step can first remove most loose dirt from the surface of the MBR flat membrane 12, reducing the burden on the subsequent scrubbing step. The scrubbing step can more effectively remove residual stubborn stains and attachments. Because flushing has already removed most of the dirt, the force and time required for scrubbing are reduced, thereby improving cleaning efficiency. Preferably, the outer surface of the cleaning roller 15 is coated with a sponge.

[0033] Specifically, the bottom end of the conveying channel is equipped with multiple supporting wheels 7 along the feed direction, and multiple limiting wheels 8 are symmetrically arranged on both sides of the top end of the conveying channel along the feed direction. By providing the supporting wheels 7 and limiting wheels 8, the MBR flat membrane 12 is supported by the supporting wheels 7, and the MBR flat membrane 12 is limited by the limiting wheels 8, so that the MBR flat membrane 12 is conveyed in a vertical position within the conveying channel, while reducing friction, so that the conveying mechanism 5 can drive it to move. The positioning of the limiting wheels 8 corresponds to the position of the upper frame of the MBR flat membrane 12 to avoid damage to the filter membrane.

[0034] In order to prevent the bottom end of the MBR flat membrane 12 from deflecting, a wheel groove adapted to the thickness of the MBR flat membrane 12 is opened in the middle of the supporting wheel 7 .

[0035] In some embodiments, there are two conveying mechanisms 5, located at the top and bottom of the conveying channel, respectively. The drive mechanism includes rollers 9, each of which is provided at both ends of the inner portion of the conveying belt 10. The rollers 9 are driven by a servo motor, which in turn drives the conveying belt 10. Preferably, the rollers 9 are synchronous wheels, and the conveying belt 10 is a synchronous belt.

[0036] By arranging the conveying mechanism 5 at the top and bottom ends of the conveying channel, the MBR flat membrane 12 can be driven simultaneously from both the upper and lower ends, so that the force is balanced and deviation is avoided during feeding.

[0037] To prevent contact between the entrainment belt 10 and the filter membrane, which could damage it, the entrainment belt 10 is positioned to correspond to the frame of the MBR flat membrane 12. The entrainment belt 10 acts on the frame of the MBR flat membrane 12 to drive the MBR flat membrane 12 to move. To increase friction and prevent relative sliding between the entrainment belt 10 and the MBR flat membrane 12, elastic bumps 11 are fixedly attached to the outside of the entrainment belt 10.

[0038] In order to facilitate the insertion of the MBR flat membrane 12 into the conveying channel, a guide plate 1 is provided on the feed side of the conveying mechanism 5. The guide plate 1 is fixedly connected to the bracket 2. Under the guidance of the guide plate 1, the MBR flat membrane 12 is aligned with the conveying channel; the bottom end of the guide plate 1 is fixedly connected to a push plate 6. By setting the push plate 6, the MBR flat membrane 12 is supported and limited.

[0039] Specifically, the spraying direction of the spray heads 13 is tilted downward. By providing the spray heads 13 with a downward-tilted spraying direction, dirt on the outer surface of the MBR flat membrane 12 is flushed down, improving the flushing effect. Preferably, multiple spray heads 13 form a flushing zone parallel to the conveying channel. The flushing zone is parallelogram-shaped, with the upper side of the flushing zone tilted toward the feed end of the conveying channel. This allows the zone to preferentially flush the upper end of the MBR flat membrane 12, and then gradually flush from top to bottom. This prevents dirt from sliding down the area below the MBR flat membrane 12 after flushing, causing secondary contamination of the area below.

[0040] In order to prevent the cleaning roller 15 from pushing the MBR flat membrane 12 to move under the influence of friction, thereby affecting the cleaning effect, the rotation direction of the cleaning roller 15 is opposite to the feeding direction, and the cleaning roller 15 is driven to rotate by a servo motor.

[0041] To further enhance the cleaning effect, the scrubbing mechanism 4 further includes a plurality of cleaning pipes 16. A nozzle 17 is connected to the side of the cleaning pipes 16 facing the conveying channel. The cleaning rollers 15 and the cleaning pipes 16 are arranged alternately. The nozzles 17 ensure that the cleaning rollers 15 and the MBR flat membrane 12 are rinsed after the cleaning rollers 15 scrub.

[0042] In some embodiments, the outer side of the limiting wheel 8 is provided with a wheel groove for limiting the position of the conveyor belt 18. Conveyor belts 18 are sleeved around the outer sides of multiple limiting wheels 8 located on the same side of the conveying channel. Elastic blocks 19 are fixedly connected to the outer sides of the conveyor belts 18, and the conveyor belts 18 are driven by a servo motor. By placing the conveyor belts 18 outside the limiting wheel 8 and the elastic blocks 19, the friction between the conveyor belts 18 and the frame of the MBR flat membrane 12 is increased, thereby clamping and conveying the MBR flat membrane 12, thereby delivering the MBR flat membrane 12 from the conveying channel. The conveyor belts 18 and the conveyor belt 10 have the same belt speed.

[0043] See also Figure 6 As shown, in some embodiments, multiple delivery channels are arranged in parallel to further improve the cleaning efficiency.

[0044] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
