[0028] Please refer to Figures 1 - 5, The membrane surface cleaning structure of a wastewater membrane processor, including a treatment tank 1. A fixing plate 2 is inserted into the treatment tank 1 through a slot 13 opened on its top side wall. A composite membrane 3 for filtering wastewater is provided on the fixing plate 2. Inside the treatment tank 1, a cleaning member 4 in contact with the surface of the composite membrane 3 is installed on one side close to the water inlet pipe 11. The cleaning member 4 includes a sliding plate 41 slidably connected to the inside of the treatment tank 1. On the side of the sliding plate 41 close to the composite membrane 3, a scraping plate 45, a brush 46, and a sponge brush 47 are arranged in sequence from bottom to top.

[0029] In this embodiment, a water outlet pipe 12 is installed on one side of the treatment tank 1 away from the water inlet pipe 11. A box groove 14 is opened on the bottom surface inside the treatment tank 1 directly below the cleaning member 4. A sewage collection box 5 is slidably inserted into the box groove 14; the design of the sewage collection box 5 facilitates the collection of solid stains cleaned from the composite membrane 3 by the cleaning member 4. A sealing ring is provided between the connection of the sewage collection box 5 and the side wall opening of the treatment tank 1 for sealing, and a sealing ring is provided between the fixing plate 2 and the side wall of the slot 13 on the treatment tank 1 for sealing.

[0030] Furthermore, T-shaped sliding grooves 15 are opened on both inner walls of the treatment tank 1 perpendicular to the slot 13. A threaded rod 42 and a sliding rod 43 are respectively rotatably connected in the two T-shaped sliding grooves 15. At both ends of the sliding plate 41 close to the side wall of the treatment tank 1, T-shaped sliders 411 adapted to the T-shaped sliding grooves 15 are welded and fixed. A threaded hole 412 adapted to the threaded rod 42 is opened on the T-shaped slider 411 on the side close to the threaded rod 42, and a through hole 413 adapted to the sliding rod 43 is opened on the T-shaped slider 411 on the side close to the sliding rod 43; the T-shaped slider 411 is threadedly connected to the threaded rod 42, so that when the threaded rod 42 rotates, the sliding plate 41 slides up and down.

[0031] Secondly, a motor 49 is installed on the top of the treatment tank 1 close to the side where the threaded rod 42 is located. The output shaft of the motor 49 is coaxially connected to the threaded rod 42; the design of the motor 49 provides power for the rotation of the threaded rod 42.

[0032] Furthermore, three grooves are opened on the side of the sliding plate 41 close to the composite membrane 3.

[0033] Secondly, the lengths of the scraping plate 45, the brush 46, and the sponge brush 47 are all equal to the width of the composite membrane 3. One ends of the scraping plate 45, the brush 46, and the sponge brush 47 close to the composite membrane 3 are all in contact with its surface; the contact makes it possible that when the sliding plate 41 slides up and down, the scraping plate 45, the brush 46, and the sponge brush 47 can clean the stains on the surface of the composite membrane 3 in detail.

[0034] Further, when the sliding plate 41 moves to the highest end along the threaded rod 42, the top of the sponge brush 47 and the top of the composite film 3 are on the same horizontal plane; when the sliding plate 41 moves to the lowest end along the threaded rod 42, the scraping plate 45 and the bottom of the composite film 3 are on the same horizontal plane; so that the cleaning member 4 can comprehensively clean the surface of the composite film 3.

[0035] Working principle: When the membrane surface cleaning structure of the waste water membrane processor of the present utility model is in use, the user first fixes the composite film 3 on the fixing plate 2, inserts the fixing plate 2 into the processing tank 1 through the slot 13, and then drives the motor 49 to drive the threaded rod 42 to rotate, so that the sliding plate 41 slides up and down, and then the scraping plate 45, the brush 46 and the sponge brush 47 thereon clean the stains on the surface of the composite film 3, and the solid stains cleaned fall into the dirt collection box 5.
