The end of one group of rotating rods 6 is connected to the output end of the motor 5. A filter screen 7 is sleeved on the two groups of rotating rods 6. The filter screen 7 is located below the water inlet pipe 4, and the left side of the filter screen 7 is lower and the right side is higher. A collection frame 8 is fixedly arranged in the filtration tank 1. The collection frame 8 is located at the lower right of the filter screen 7. A scraping plate 9 is fixedly installed on the collection frame 8. The end of the scraping plate 9 is in contact with the filter screen 7, and the whole scraping plate 9 is inclined to the right. A water filtering layer 10 is fixedly arranged on the collection frame 8. A surrounding mechanism is fixedly arranged in the filtration tank 1. The surrounding mechanism includes a fixed rod 11. The fixed rod 11 is fixedly installed in the filtration tank 1. A side plate 12 is fixedly arranged on the fixed rod 11. A baffle 13 is fixedly arranged on the side plate 12. There are two groups of side plates 12, and both the side plates 12 and the baffle 13 are in contact with the filter screen 7. There are two groups of scraping plates 9.

[0020] Specifically, when treating printing and dyeing wastewater, the motor 5 drives the filter screen 7 to rotate cyclically through the rotating rod 6. The wastewater enters the filtration tank 1 from the water inlet pipe 4. The cyclically rotating filter screen 7 filters the wastewater, and at the same time brings the intercepted fiber fluffs to the rightmost side, and then scrapes them off the filter screen 7 by the two groups of scraping plates 9 and drops them into the collection frame 8. The filtered wastewater enters the mixing tank 3 to facilitate subsequent wastewater treatment. The filtering treatment effect is good, and through the cooperation of the side plate 12 and the baffle 13, the splashing of wastewater can be effectively prevented.

[0021] Please refer to 2 and Figure 5 , A cleaning cover 14 is fixedly arranged on the filtration tank 1. A cross bar 15 is fixedly arranged on the cleaning cover 14. A pulling plate 16 is fixedly arranged on the cross bar 15. The pulling plate 16 and the cross bar 15 are located in the collection frame 8.

[0022] Specifically, when cleaning the fiber fluffs, the wastewater on the fibers and fluffs separates from the water filtering layer 10. Loosen the fixing bolt 24 and pull out the cleaning cover 14. Pull the cleaning cover 14 and the pulling plate 16, so that the accumulated fibers and fluffs in the collection frame 8 can be scraped off, which is quick to clean and the operation is simple and convenient.

The three outlet pipes 26 are evenly arranged above the filter screen 7. The ends of the three outlet pipes 26 are all located between the two side plates 12.

[0024] Specifically, when sewage is introduced, the net plate 19 intercepts larger-sized sundries carried in the sewage, facilitating better filtration by the subsequent filter screen 7. And by arranging the three outlet pipes 26 on the filter screen 7, the sewage entering through the water inlet pipe 4 is split by the three outlet pipes 26, effectively increasing the contact area between the sewage and the filter screen 7 and improving the filtration effect.

[0025] In summary, when the overall device is in use: When treating printing and dyeing sewage, the motor 5 drives the filter screen 7 to rotate cyclically through the rotating rod 6. The sewage enters the filtration tank 1 from the water inlet pipe 4. The cyclically rotating filter screen 7 filters the sewage, and at the same time, the intercepted fiber fluffs are brought to the rightmost side, and then are scraped off the filter screen 7 by the two scraping plates 9 and fall into the collection box 8. The filtered sewage enters the mixing tank 3, facilitating subsequent sewage treatment. The filtration treatment effect is good, and through the cooperation of the side plates 12 and the baffle 13, sewage splashing can be effectively prevented.

[0026] When cleaning the fiber fluffs, the sewage on the fibers and fluffs detaches from the water filtering layer 10. By loosening and fixing the bolt 24, the cleaning cover 14 can be pulled out. Pull the cleaning cover 14 and the pull plate 16, and thus the accumulated fibers and fluffs in the collection box 8 can be scraped off, with quick cleaning and simple and convenient operation.

[0027] Specifically, when sewage is introduced, the net plate 19 intercepts larger-sized sundries carried in the sewage, facilitating better filtration by the subsequent filter screen 7. And by arranging the three outlet pipes 26 on the filter screen 7, the sewage entering through the water inlet pipe 4 is split by the three outlet pipes 26, effectively increasing the contact area between the sewage and the filter screen 7 and improving the filtration effect.
