Device for adding polyethylene oxide in papermaking process

The invention relates to a device for adding polyethylene oxide in a papermaking process. The device comprises a polyethylene oxide dissolution barrel, a first screw pump, a polyethylene oxide diluting tank, a second screw pump and a paper machine flow box which are connected to one another sequentially, wherein a filter screen is arranged between the first screw pump and the polyethylene oxide diluting tank; polyethylene oxide exits from the first screw pump and then passes through the filter screen so as to form a large amount of uniform and clean stripy polyethylene oxide, the uniform and clean stripy polyethylene oxide enters the polyethylene oxide diluting tank, and undissolved lumps, fallen rotten materials in pipelines and impurities are intercepted on the filter screen. Compared with the prior art, the device has the advantages of ensuring the uniformity and cleanliness of the polyethylene oxide entering the paper machine flow box, avoiding the occurrence of eyes due to the polyethylene oxide problem,
