[0027] Specific working principle:

[0028] When it is necessary to filter the wastewater, firstly, wastewater is added to the inside of the filter box 1 through the liquid adding pipe 11. When the wastewater passes through the first filter box 4 and the second filter box 5, the first filter box 4 filters the impurities with larger volume, and the second filter box 5 filters the impurities with smaller volume. The filtered impurities are respectively stored in the first filter box 4 and the second filter box 5. The filtered water is collected and transported to the inside of the filter element 8 through the funnel 6 and the guide pipe 7. The filter element 8 filters the wastewater again. The filtered water accumulates in the inner cavity of the filter box 1. After the filtration is completed, the filtered water is discharged out of the filter box 1 by starting the drainage pump 12. The water can be discharged. When the first filter box 4 and the second filter box 5 need to be cleaned, the electric push rod 16 is first started through the external controller. The output end of the electric push rod 16 drives the back plate 17 to move forward, and the back plate 17 cooperates with the connecting plate 18 to drive the sealing plate 10 to move, so that the sealing plate 10 is separated from the front of the filter box 1. After separation, the first filter box 4 and the second filter box 5 can be pulled out through the pull rings on the front of the filter box 1. This solves the problem in the prior art that the filter screen is usually installed inside the filter device, making it difficult to clean the clogged filter screen, thereby affecting the filter screen's effect on wastewater filtering.
