Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, and more specifically, to a feeding device for the production of bactericides in a retention aid system. Background Art

[0002] Retention aids are important additives used in the papermaking process. The function of papermaking retention and filtration aids is to increase the retention rate of pulp when it is put on the screen. It has excellent retention effect on fine fibers and fillers (calcium carbonate, titanium dioxide and kaolin, etc.). In the papermaking process, due to the use of a large amount of water, chemicals and organic substances, a good environment is provided for the growth and reproduction of microorganisms. If these microorganisms are not controlled, they will not only affect the quality of paper, but also cause corrosion of equipment and shutdown of production lines. The use of papermaking fungicides can effectively inhibit and prevent the growth and reproduction of microorganisms, thereby ensuring the quality of paper and the stability of production. At the same time, it can also improve the adhesion of pulp and the strength of paper, making paper more durable and applicable. Typical fungicides on the market include isothiazolinones, triazine, etc. When producing retention aids, it is necessary to transport the raw materials and solvents to the reactor for stirring and mixing.

[0003] The existing reactor adopts a single feeding method. The moisture in the reactor can easily enter the raw materials, causing the raw materials to agglomerate and unable to be fed subsequently, and quantitative feeding cannot be guaranteed. At the same time, the increase in moisture in the raw materials will affect the quality of disinfectant production. Utility Model Content
