AI Technical Summary
Powdered materials tend to stick inside the feed pipe of traditional pneumatic conveyors, affecting normal feeding.
An airflow blowing device is installed inside the unloading pipe. The airflow generated by the blower blows the material downward through the guide pipe and the split pipe. Combined with the design of the rotating rod and fan blades, the material in the unloading pipe is cleared.
This effectively prevents materials from sticking to the inner wall of the discharge pipe, keeps the discharge pipe unobstructed, and ensures normal discharge.
