AI Technical Summary

Technical Problem

The feed produces dust during the screening process, causing air pollution and causing harm to the health of staff.

Method used

A feed anti-dust screening device is designed, including a shell, dust collecting cover, dust collecting tube, dust collecting fan, screening component and drive component. The screening component is driven to swing back and forth through the drive component, and lifted when screening feed. The dust is blocked by the dust collecting cover and is introduced into the dust collecting equipment through the dust collecting tube and the dust collecting fan for processing.

Benefits of technology

Effectively prevent the fine powder substances in the feed from drifting into the air, reduce air pollution, and reduce the harm to the health of staff.
