When the water level in the treatment cavity 17 is higher than the water level of the clean water cavity 18 and gradually rises to the electronic water level meter 31 (the filter plate 7 is gradually blocked or impurities in the treatment cavity 17 are gradually deposited), the electronic water level meter 31 transmits signals to the control panel 3, the control panel 3 controls the micro motor 4 to rotate, the water inlet 11 is closed through the cooperation of the gear cylinder 41, the toothed plate 42 and the water stop valve plate 131, the cleaning opening 13 is opened, the water stop valve plate 131 drives the connecting rod 53 to move upwards while the water stop valve plate 131 moves, the cleaning frame 5 is driven by the connecting rod 53 to move upwards in the treatment cavity 17, impurities attached to a movement path are scraped under the action of the L-shaped scraper 51, and the scraped impurities are mixed in water until the water carries the scraped impurities to be discharged through the cleaning opening 13; when the water flow is discharged through the cleaning port 13, the fan blade wheel 6 rotates in the drainage tank 2, so that the fan blade wheel 6 drives the U-shaped rod 61 arranged in the middle to do circular motion, the transmission rod 63 sleeved on the U-shaped rod 61 reciprocates up and down, one end of the transmission rod 63 drives the filter plate 7 to reciprocate up and down in the movable groove 16, friction is generated between the self motion and water, impurities attached to the self motion are separated, the separated impurities are mixed in the water, and the impurities are discharged along with the water through the cleaning port 13.
After the control panel 3 sets time and reaches the designated time, the water in the treatment cavity 17 and the clean water cavity 18 is completely discharged, so that the control panel 3 controls the micro motor 4 again to rotate reversely, the water inlet 11 is opened, the cleaning port 13 is closed, sewage is purified again, and the steps are repeated to realize automatic sewage purification and back flushing of the filter plate 7.
In summary, the application does not need to adopt other equipment to be additionally arranged in the clean water tank 1 for flushing, does not need to manually disassemble the clean water tank 1, ensures the cleanliness in the filter plate 7 and the treatment cavity 17 in each back flushing process, is convenient for subsequent treatment quality, improves the primary sewage purification efficiency, has simple integral structure and low cost, and is also convenient for later maintenance.
Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present application and not for limiting the same, and although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present application, which is intended to be covered by the scope of the claims of the present application.
