[0039] (1) By opening the movable cover 24, the wastewater to be filtered can be poured into the inner side of the filter box 1 through the feed pipe 23, and the wastewater can be filtered through the filter plate 2. The wastewater will flow to the inner bottom wall of the filter box 1 through the filter holes on the inner side of the filter plate 2, while the particles and impurities in the wastewater will remain above the filter plate 2, thereby achieving the purpose of wastewater filtering.

[0040] (2) The threaded rod 6 can be driven to rotate by the motor 5. Since the threaded rod 6 is threadedly connected to the threaded push block 7, the threaded rod 6 will drive the threaded push block 7, the movable rod 8 and the scraper plate 9 to move left and right in turn during the rotation of the threaded rod 6.

By adjusting the fixed valve 18, the wastewater filtered inside the filter box 1 can be discharged through the outlet pipe 17.

[0042] (4) The filter box 1 can be moved by four universal wheels 19 and can be moved to a designated location for use. The universal wheels 19 can be fixed by setting a brake 20 to prevent the four universal wheels 19 from moving during use of the filter box 1, thereby ensuring the effect of the filter box 1 on filtering wastewater.
