摘要: 为解决岩土工程废浆处理时面临的泥浆回收率低、设备自动化运行水平低等问题，根据岩土工程施工泥浆特点，研制了一种新型高效智能泥水分离系统。该系统采用振动与旋流相结合的二级分离工艺，可根据液面高度变化情况自动控制设备开关机与调速，并将运行数据上传至云端供技术人员分析查看。系统研制完成后通过室内实验验证了设备性能，并探究了泥浆参数对颗粒去除率的影响规律，结果表明，来浆流量和筛网规格不变时，设备颗粒去除率与固相颗粒尺寸和泥浆粘度有关，受固相含量影响不明显，分离效果可满足现场泥浆环保净化处理需求，该系统工作期间能够实现无人值守，可有效分离泥浆中大颗粒有害固相，提高泥浆重复利用率，降低工人劳动强度，节约施工成本。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.
