Description
Technical Field
[0001] This utility model relates to the field of polymer technology, specifically to a powdered polymer storage device that facilitates quantitative feeding. Background Technology
[0002] Powdered polymers are widely used in chemical, water treatment and other fields. The stability of their storage and feeding processes directly affects production efficiency and product quality. These materials are prone to clumping due to factors such as moisture absorption and standing, and they are also prone to forming arches in the discharge area of the storage device, which will prevent the material from flowing out smoothly and hinder subsequent feeding operations.
[0003] Existing powder storage devices mostly only have basic storage functions and are insufficient in solving the problems of agglomeration and arching. Although some devices are equipped with simple stirring structures, the stirring force and range are limited, making it difficult to completely break up agglomerates. Furthermore, there is no specific design to deal with arching in key areas such as the discharge hopper. Agglomeration and arching of materials will cause uneven discharge, which will not only reduce feeding efficiency but also lead to deviations in quantitative accuracy. Frequent manual intervention and cleaning are required, increasing operating costs and labor intensity. They cannot meet the needs of continuous and accurate feeding in industrial production. Therefore, we propose a powdered polymer storage device that facilitates quantitative feeding. Utility Model Content
