[0032] Specifically, the dyeing wastewater flows into the stirring barrel 110 through the water inlet pipe 140, the electric valve is installed on the water outlet pipe 160 and the drain pipe 211, the appropriate flocculating agent is added into the stirring barrel 110 through the feeding hopper 150, the motor one 130 is started, the motor shaft of the motor one 130 is driven on the stirring rod 120, the stirring rod 120 fully stirs the water in the stirring barrel 110, so that the flocculating agent is fully mixed with the wastewater to form flocculation, after the stirring reaction is completed, the wastewater is discharged from the two water outlet pipes 160 into the filter box 210, and the impurities in the wastewater are intercepted and filtered by the filter plate 220, the wastewater filtered of large-particle impurities is discharged from the drain pipe 211 through the filter plate 220, and is further subjected to depth treatment to reach the recycling standard, and the impurities remaining on the surface of the filter plate 220 can be cleaned by the driving unit 230 and the cleaning assembly 240.

[0033] As shown in Figure 6 the embodiment, the cross-sectional shape of the filter plate 220 is V-shaped, a plurality of filter holes 221 are formed on the surface of the filter plate 220, and a rectangular groove 222 is formed on the top surface of the filter plate 220 at the positions of the two highest points.

[0034] In the embodiment, the V-shaped design helps to form a certain flow rate of the wastewater on the surface thereof, so as to promote the sedimentation and filtration of the large-particle impurities, and the two water outlet pipes 160 are close to the lowest points of the filter plate 220, so as to avoid the wastewater from flowing away from the rectangular groove 222.

[0035] As shown in Figures 4-5 the embodiment, the cleaning assembly 240 includes two moving blocks 241, the side walls of the two moving blocks 241 are provided with threaded holes, the two moving blocks 241 are respectively screw-connected with the outer walls of the lead screw one 231 and the lead screw two 233, the bottom surfaces of the two moving blocks 241 are fixedly connected with circular rods 242, the bottom ends of the two circular rods 242 are fixedly connected with limiting plates 2421, a connecting plate 243 is arranged below the two circular rods 242, two circular holes are formed on the top surface of the connecting plate 243, the outer walls of the two circular rods 242 are respectively slidably inserted into the two circular holes, the bottom surface of the connecting plate 243 is fixedly connected with a scraper 244, the bottom end of the scraper 244 is in contact with the surface of the filter plate 220, the outer walls of the two circular rods 242 are respectively sleeved with return springs 245, the two return springs 245 are respectively sleeved on the outer walls of the circular rods 242, one end of the return spring 245 is fixedly connected with the bottom surface of the moving block 241, the other end of the return spring 245 is fixedly connected with the top surface of the connecting plate 243, the threads on the left and right ends of the lead screw one 231 are opposite in rotation direction, and the threads on the left and right ends of the lead screw two 233 are opposite in rotation direction.

[0036] In specific implementation, the two cleaning assemblies 240 are symmetrical to each other and are located at the lowest point of the filter plate 220, so as to divide the surface of the filter plate 220 into two halves. The wastewater discharged by the two water outlets 160 falls on the two sides of the cleaning assembly 240, and the large-particle impurities on the two sides move to the lowest point of the filter plate 220 through sedimentation and are blocked by the two scrapers 244.

The outer side wall of each of the two collecting boxes 260 is fixedly connected with two handles 261, and the top end opening of each of the two collecting boxes 260 corresponds to the rectangular groove 222.

[0038] In specific implementation, the two partition plates 250 and the filter plate 220 form an M shape, so that the inside of the filter box 210 is intercepted to form a flowing space for the filtered wastewater, and a space for placing the collecting box 260 is reserved. The impurities pushed down from the rectangular groove 222 by the scraper 244 will fall into the collecting box 260 for collection, and can be treated regularly.
