AI Technical Summary
Solid powders are prone to clumping at the feed inlet or localized accumulation due to electrostatic adsorption, affecting flowability. Existing screw pump devices cannot effectively solve this problem.
A screw pump device including a rotating component, a feeding component, a clearing component, and a shielding component was designed. The angle of the feeding component is adjusted by rotation, the powder is dispersed by the clearing component, and the powder is prevented from flying out by the shielding component, so as to achieve continuous feeding.
It effectively avoids powder clogging, ensures continuous conveying of solid powder, and improves the flexibility and adaptability of the equipment.
