[0025] Specifically, the structure that the driving plate 4 is in transmission connection with the motor 6 is as follows: the upper and lower ends of the membrane frame 1 are fixedly provided with a first support plate 7 and a second support plate 8 respectively, two transmission screw rods 9 are rotatably arranged between the first support plate 7 and the second support plate 8, one end of each of the two transmission screw rods 9 is located on one side of the two ends of the driving plate 4 and is screwed on the driving plate 4, the two transmission screw rods 9 are linked through the cooperation of a synchronous wheel and a synchronous belt, and the motor 6 is arranged on the first support plate 7 and is in transmission connection with one of the transmission screw rods 9. Through the above structure, the motor 6 drives the transmission screw rod 9 connected with the motor 6 to rotate, and the other transmission screw rod 9 rotates synchronously through the cooperation of the synchronous wheel and the synchronous belt, and the two transmission screw rods 9 drive the driving plate 4 to realize stable longitudinal movement through the screwing cooperation with the driving plate 4.

[0026] Specifically, the structure that the driving plate 4 is slidingly arranged on the film frame 1 is that a plurality of guide rods 10 are arranged between the first support plate 7 and the second support plate 8 and located at one side of both ends of the driving plate 4, a plurality of guide sleeves 42 are formed on the driving plate 4 and sleeved on the guide rods 10, and sliding bearings are arranged between the guide sleeves 42 and the guide rods 10. Through the above structure, the guide sleeves 42 and the guide rods 10 cooperate to guide the driving plate 4 when the driving plate 4 moves longitudinally, so that the longitudinal movement of the driving plate 4 driven by the motor 6 is more stable and smooth.

[0027] Specifically, the structure that the scraping ring 5 is arranged in the mounting hole 41 is that a mounting ring groove 43 matched with the mounting ring is formed on the inner wall of the mounting hole 41, and the outer side end of the scraping ring 5 is clamped into the mounting ring groove 43. Through the above structure, the scraping ring 5 is stably kept in the mounting hole 41 and kept in contact with the outer surface of the filter membrane element 3, and the installation is convenient.

[0028] In the above structure, under normal circumstances, the motor 6 drives the driving plate 4 to move the plurality of scraping rings 5 upward along the filter membrane element 3 to the highest end, so that the driving plate 4 and the scraping ring 5 do not interfere with the work of the filter membrane element 3. After long-term work, when it is necessary to remove the gel layer on the outer surface of the filter membrane element 3, the motor 6 drives the driving plate 4 to repeatedly move the scraping ring 5 up and down, so that the scraping ring 5 reciprocally scrapes on the outer surface of the filter membrane element 3, and the gel layer adhered to the outer surface of the filter membrane element 3 is completely removed, thereby realizing the cleaning of the filter membrane element 3 and keeping the filter membrane element 3 in good filtering performance.
