The barrel cover 3 is detachably installed at the top of the filter barrel 1 by bolts (not shown in the figure), which facilitates opening the barrel cover 3 for maintenance of the filter barrel 1 after long-term use; four support legs 2 are evenly distributed and fixedly installed at the bottom edge of the filter barrel 1; the bottom inner wall of the filter barrel 1 is inclined; the drain pipe 18 is fixedly installed in the middle of the bottom of the filter barrel 1 and connected to the inside of the filter barrel 1; the drain pipe 18 is installed at the lowest point of the inclined surface inside the filter barrel 1, which facilitates impurities to slide down the inclined surface to the drain pipe 18. The water spray pipe 11 is fixedly installed on the bucket lid 3. The interior of the water spray pipe 11 is connected to the bottom end of the water pump pipe 10. Each high-pressure nozzle 12 is evenly divided into four groups and symmetrically installed at the bottom end of the water spray pipe 11. The four groups of high-pressure nozzles 12 are located directly above the four filter screens 8, which facilitates rinsing the four filter screens 8.

[0023] A fixing ring 6 is installed on the bottom wall of the filter barrel 1. A filter frame 7 is installed on the top of the fixing ring 6. Four filter screens 8 are evenly arranged inside the filter frame 7. A rotating rod 15 is rotatably connected to the middle of the filter frame 7. The top of the rotating rod 15 passes through the barrel cover 3 and is connected to a rotating motor 14. An upper cleaning brush 16 and a lower cleaning brush 17 are provided on the side wall of the rotating rod 15 near the filter frame 7. The ends of the upper cleaning brush 16 and the lower cleaning brush 17 that are close to each other are tightly attached to the top and bottom surfaces of the filter frame 7, respectively. In order to improve the stability of the filter frame 7, the filter frame 7 can be fixedly installed on the fixing ring 6 by bolt connection. A fixing ring 6 is fixedly installed on the inner bottom wall of the filter barrel 1. An inlet pipe 4 is located at the bottom of one end of the filter barrel 1, and an outlet pipe 5 is located at the top of the other end. The inlet pipe 4 and outlet pipe 5 are located on opposite sides of the fixing ring 6, and the outlet pipe 5 is installed at a height lower than the high-pressure nozzle 12. Each of the inlet pipe 4, outlet pipe 5, and drain pipe 18 is equipped with a valve (not shown in the figure) to facilitate control of the internal flow of the inlet pipe 4, outlet pipe 5, and drain pipe 18. Four insertion slots 19 are evenly distributed at the top edge of the fixing ring 6. Four insertion posts 13 are fixedly installed on the bottom edge of the filter frame 7 near the four insertion slots 19. The bottom ends of the four insertion posts 13 slide into their corresponding insertion slots 19, facilitating the limiting of the installation position of the filter frame 7 and further improving its stability. A rotating motor 14 is fixedly installed on the top of the lid 3. The rotating shaft of the rotating motor 14 is fixedly connected to the top of the rotating rod 15. The bottom end of the rotating rod 15 passes through the filter frame 7 and is rotatably connected to the filter frame 7, so that the rotating motor 14 can drive the rotating rod 15 to rotate. The upper cleaning brush 16 and the lower cleaning brush 17 are respectively set on both sides of the filter frame 7. The middle parts of the upper cleaning brush 16 and the lower cleaning brush 17 are fixedly installed on the rotating rod 15, so that the rotation of the rotating rod 15 can drive the upper cleaning brush 16 and the lower cleaning brush 17 to rotate.

[0024] When this device is working, the raw liquid to be filtered can be filtered through the filter frame 7 at the top of the fixed ring 6 and the filter screen 8. At this time, the pipe valves on the inlet pipe 4 and the outlet pipe 5 are opened to allow the raw liquid to be filtered to be introduced through the inlet pipe 4. After the impurities in the raw liquid are intercepted and filtered by the filter screen 8, the clear filtrate is discharged from the filter tank 1 through the outlet pipe 5. When the filter screen 8 needs to be cleaned, the pipe valves on the inlet pipe 4 and the outlet pipe 5 are closed. The upper cleaning brush 16 and the lower cleaning brush 17 are rotated by rotating the motor 14 to scrape off the impurities clogging the filter screen 8. The drain valve is then opened. The pipe valve on pipe 18 discharges impurities from the bottom of filter bucket 1. Then, through the flushing action of high-pressure water pump 9, water suction pipe 10, water spray pipe 11 and high-pressure nozzle 12, the impurities scraped off the filter screen 8 can be flushed towards the drain pipe 18, thus facilitating the discharge of impurities through the drain pipe 18. When cleaning the filter screen 8, it is not necessary to open the filter machine. Through the cooperation of high-pressure nozzle 12, upper cleaning brush 16 and lower cleaning brush 17, it is easy to automatically clean the impurities attached to the filter screen. This solves the problem that it is laborious and time-consuming for workers to wash the filter screen with a hand-held high-pressure water gun, and the cleaning efficiency is high.
