The filtered wastewater is discharged through the outlet 42. When the inclined filter screen 11 needs to be cleaned, the addition of wastewater is stopped in advance, and the water pump 21 pumps water and delivers it to the installation pipe 14. Finally, the water is sprayed out through the flushing nozzle 2 to clean the impurities at the bottom of the inclined filter screen 11. The installation frame 34 is pushed by the electric telescopic rod 33, which in turn pushes the baffle 32. When the baffle 32 is pushed open, the second motor 4 drives the baffle 32 to rotate 90°. The cleaned impurities and the cleaned wastewater are discharged through the outlet tank 3. The first motor 23 drives the gear 24 to rotate, and through transmission, the rack 22 drives the installation pipe 14 to slide inside the installation box 12, thereby cleaning different positions of the inclined filter screen 11. That is, no manual cleaning is required, making the operation more convenient.
