AI Technical Summary

Technical Problem

The dust generated during the crushing of waste concrete can be directly released into the air, causing environmental pollution and health hazards.

Method used

An adsorption treatment mechanism was designed, comprising a cover plate, a rotating component, a dust collection component, a cleaning component, and a pull-out filter component. The crusher is opened by rotating the cover plate, and a cyclone fan is used to create negative pressure to draw in dust. The dust is cleaned by scrapers and cleaning brushes, and the filter bag filters and intercepts the dust, thus achieving dust collection and purification.

Benefits of technology

It effectively prevents dust particles from directly escaping, improves environmental performance, ensures a clean working environment and the health of personnel, and further enhances the effect of dust collection and treatment.
