AI Technical Summary
The existing production process of wettable powder has problems of dust pollution and failure to meet environmental protection standards. In particular, dust volatilization is serious during the feeding and discharging process, which affects the health of workers. At the same time, the mixing and crushing effect is not good, which affects the product quality and stability.
A wettable powder production line was designed, including a wettable powder processing module and a dust collection module. By setting a dust collection hood and dust collector at the top of the feeding hopper, dust during the feeding process is collected, and dust at the discharge port of the mixing tank is absorbed through two pipes. At the same time, the layout of the mixing tank and the coarse mixing tank is optimized to reduce the pipe length, and negative pressure is provided by high-pressure and medium-pressure fans to ensure the drying and mixing effect of the material.
It effectively reduces dust volatilization in the workshop, ensures the health and environmental safety of workers, improves mixing and crushing effects, meets environmental protection requirements, guarantees product quality and production efficiency, and saves energy and costs.
