[0001] The utility model relates to the technical field of brightener processing, in particular to a brightener defoaming stirrer for the papermaking industry. Background Art

[0002] Brighteners are organic compounds that can improve the whiteness of fiber fabrics and paper. They are also called optical brighteners and fluorescent brighteners. Fabrics are often yellow due to the presence of colored impurities. In the past, they were decolorized by chemical bleaching. Brighteners were added to the products. The function of the brightener is to convert the invisible ultraviolet radiation absorbed by the product into purple-blue fluorescent radiation, which complements the original yellow light radiation to become white light, thereby improving the whiteness of the product under sunlight. Brighteners have been widely used in textiles, papermaking, washing powder, soap, rubber, plastics, pigments and paints as an important fine chemical product.

[0003] At present, the use of whitening agents in the papermaking industry requires a stirrer, but the existing stirrers do not have a defoaming function. In order to evenly mix the thick mixed liquid and the bubbles, a long stirring time is required, resulting in high costs and low production efficiency.
