AI Technical Summary

Technical Problem

Existing soil washing equipment is prone to problems such as mud sedimentation and accumulation at the bottom of the mixing reaction tank and separation between upper and lower layers when treating soils with high viscosity and high solid content, resulting in poor heavy metal desorption efficiency and remediation effect.

Method used

The anti-sedimentation mechanism, consisting of a conical pool bottom, a sludge pump, and a return pipe, combined with a drive motor and mixing components, enables the circulating flow of the mixed liquid, preventing sediment accumulation and promoting uniform mixing of soil and remediation agents.

Benefits of technology

It effectively prevents clogging of the mixing tank, ensures stable operation of the device, improves the efficiency of heavy metal remediation, enhances the contact between soil and chemicals, and improves the remediation effect.
