Abstract:

In order to solve the problems of low mud recovery rate and low automation level of equipment in the treatment of geotechnical engineering waste slurry， a new high-efficiency intelligent mud separation system is developed based on the characteristics of geotechnical engineering slurry. The system adopts a two-stage separation process which combines vibration and swirling flow. It can automatically control the equipment’s on-off and speed based on the mud level. It can also upload the operating data to the cloud for engineers for analysis. After the completion of system development， the performance of the equipment was verified through indoor experiments and the influence of mud parameters on solid-liquid separation efficiency was explored. The results showed that， when the slurry flow rate and screen size unchanged， the particle removal rate is related to the size of solid particles and the viscosity of slurry， and the influence of the solid content is not obvious. The separation effect can meet the environmental purification treatment requirements of on-site mud. Over the duration of the workload， the system can achieve unmanned automation control and effectively separating large harmful solid particles. The invention of this equipment can significantly improve the reuse rate of mud， reduce labor intensity and save construction costs.
