A driving motor 42 is fixedly connected to the top of the mounting box 41. The driving motor 42 is a variable frequency motor and is connected to the control system and the power supply through a wire. A driving rod 43 is fixedly connected to the output end of the driving motor 42. The end of the driving rod 43 away from the driving motor 42 passes through the mounting box 41 and extends to the inside of the mounting box 41. The end of the driving rod 43 located inside the mounting box 41 is fixedly connected to a driving wheel 44. The top end of the driving shaft 9 passes through the sealing cover 2 and the mounting box 41 and extends to the inside of the mounting box 41. The end of the driving shaft 9 located inside the mounting box 41 is fixedly connected to a driven wheel 45 that matches the driving wheel 44. A cleaning brush 10 is provided at the end of the driving shaft 9 located inside the mounting cylinder 1 through a transmission mechanism 5. The transmission mechanism 5 is used to drive the cleaning brush 10 to fit the inner wall of the filter cylinder 6.

[0025] Through the coordinated arrangement among the driving mechanism 4, the transmission mechanism 5 and the cleaning brush 10, the driving motor 42 drives the cleaning brush 10 to rotate along the inner wall of the filter cylinder 6 through the transmission mechanism 5 to clean the filter cylinder 6 and ensure the filtering efficiency of the filter.

[0026] Figure 3 and 4 A second embodiment is shown, which mainly differs from the first embodiment in that the transmission mechanism 5 includes a support ring 51, which is fixedly connected to the surface of the drive shaft 9, a support spring 52 is fixedly connected to the top of the support ring 51 and located on the surface of the drive shaft 9, the support spring 52 is in a compressed state, a connecting ring 53 is fixedly connected to the top of the support spring 52, a support rod 54 is fixedly connected to the surface of the connecting ring 53, and the end of the support rod 54 away from the connecting ring 53 is fixedly connected to the cleaning brush 10, a guide groove 55 is provided on the surface of the drive shaft 9, a guide block 56 is fixedly connected to the inner wall of the connecting ring 53, and the guide block 56 is slidably connected to the guide groove 55.

[0028] During use, the filtered liquid enters the interior of the installation cylinder 1 through the liquid inlet pipe 7, and is discharged from the installation cylinder 1 through the liquid outlet pipe 8 after being filtered by the filter cylinder 6. When the filter cylinder 6 needs to be cleaned, the drive motor 42 is turned on through the control panel. The drive motor 42 drives the driving wheel 44 to rotate through the driving rod 43. The rotation of the driving wheel 44 drives the driven wheel 45 and the driving shaft 9 to rotate together through the meshing action. The rotation of the driving shaft 9 drives the cleaning brush 10 to rotate through the transmission mechanism 5 to scrape the inner wall of the filter cylinder 6. During the scraping process, the connecting ring 53 slides upward along the surface of the driving shaft 9 through the support spring 52 and drives the cleaning brush 10 to fit the inner wall of the filter cylinder 6 through the support rod 54.
