AI Technical Summary
Microsilica powder tends to clump in the silo, resulting in poor flowability, difficulty in feeding, and reduced blower efficiency. Existing positive pressure conveyors are unable to solve the clumping problem.
A positive pressure conveying device for microsilica powder was designed, comprising a storage bin, a blowing bin, a rotary feeder, and a stirring rod. The rotary feeder drives the stirring rod to rotate to prevent clumping, and the microsilica powder is fed into the conveying pipe by a positive pressure fan.
It effectively prevents the clumping of microsilica powder, ensures smooth material feeding, improves the blowing efficiency of the blower, and achieves continuous conveying.
