The side of the discharge plate 4 away from the sieve plate 2 is inclined to the bottom side of the filter box 1, a through hole is formed on the end of the discharge plate 4 away from the sieve plate 2, and the end of the discharge plate 4 is communicated with the outside of the filter box 1.

[0037] Therefore, the water flow entering the filter box 1 from the water inlet pipe 11 can be filtered by the sieve plate 2, and the large diameter impurities are blocked on the upper end of the sieve plate 2, and then the filtered water flow can enter the sediment tank 9 for sedimentation.

[0038] The sieve plate 2 is provided with a scraper 5 on the upper end, and a moving mechanism 6 is arranged on the sieve plate 2 for driving the scraper 5 to scrape the impurities blocked on the sieve plate 2 to the side of the discharge plate 4.

[0040] A connecting rod 65 is arranged between the connecting shaft 64 and the driving disc 62, and the connecting rod 65 is arranged in the shape of a door. The ends of the connecting rod 65 are rotatably connected with the connecting shaft 64, and a supporting rod 66 is fixedly connected to the middle segment of the connecting rod 65, and the end of the supporting rod 66 away from the vertical shaft 63 is ball-hinged with the driving disc 62.

[0041] The driving assembly 67 comprises a plurality of fan blades 671, which are fixedly connected to the arc-shaped side wall of the rotating shaft 61 and are equidistantly arranged around the axis of the rotating shaft 61, and the fan blades 671 are arranged below the water inlet pipe 11.

[0042] When the water flow of the water inlet pipe 11 falls, the fan blade 671 can receive the power of the river water falling, so that the fan blade 671 drives the rotating shaft 61 to rotate, and at the same time can shunt the river water flow, and then the rotating shaft 61 can drive the driving disc 62 to rotate, and then the connecting rod 65 hinged with the driving disc 62 through the supporting rod 66 can reciprocatingly swing up and down, and then the vertical shaft 63 is driven to repeatedly rotate through the connecting shaft 64, so that the scraper 5 fixedly connected to the vertical shaft 63 reciprocatingly scrapes the upper end face of the sieve plate 2. The large-diameter impurities attached to the sieve plate 2 enter the discharge plate 4. At the same time, in order to improve the scraping efficiency of the scraper 5, a pressurizing pump 12 for improving the impact force of the river water on the fan blade 671 is installed on the water inlet pipe 11.

The rotating shaft 61 drives the scraper 5 to move through the driving disc 62 and the vertical shaft 63, and then the scraper 5 sweeps the impurities blocked on the sieve plate 2 to the side of the discharge plate 4, and the impurities are discharged from the filtering box body 1 through the discharge plate 4, at the same time, the abutment rod 341 moves together with the hopper 31, then the abutment rod 341 abuts against the driving rod 344, and drives the blocking block 343 to intermittently cancel the blocking of the discharge pipe 342, so that part of the coagulant overflow through the gap between the blocking block 343 and the discharge pipe 342, and finally enters the filtering box body 1 through the material scattering pipe 32. Then, the river water can sequentially pass through the sedimentation of the sedimentation tank 9, the adsorption of water impurities of the adsorption assembly 7, and the disinfection of the disinfection assembly 8 to complete the pretreatment process of the river water.
