摘　　要：将梭锥管混浊流体分离装置(简称梭锥管)用于混水泥沙分离。采用均匀正交试验考察了锥圈间距、进流量、倾角以及底孔孔径对梭锥管的耗水率和表面负荷率的影响。通过PPR和极差分析得出:影响耗水率的各因素主次排列为底孔孔径、进流量、锥管偏角和锥圈间距;而影响表面负荷率的各因数主次排列为底孔孔径、进流量、锥圈间距和锥管倾角。考虑试验因素对耗水率和表面负荷率影响程度的影响及它们在分离中所起作用的大小,优化了装置参数,水平优化表明:当锥圈间距2 cm,进流量14.5 cm3/s,倾角60°和底孔孔径2mm时,耗水率最小,表面负荷率最大。The turbid flow isolation device——shuttle-conical tube,is used to mix water sediment separation.Uniform orthogonal is adopted to investigate the influence of ring tube spacing,on the flow,the influence of cone angle and bottom outlet aperture on water consumption and surface loading rate.By PPR and range analysis,the results show that the impact of water consumption rate of primary and secondary ranked as the bottom outlet aperture,into the flow,cone angle and cone ring tube spacing;the impact of the main parameters of the surface loading rate rank as the bottom outlet aperture.Experimental factors to consider water consumption rate and surface loading rate affect the degree of influence and their role in the separation of the size of optimized device parameters.It shows when the cone ring spacing is 2 cm,the flow is 14.5 cm3/s,the angle is 60 ° and the bottom aperture is 2mm,the water consumption rate is very small,the surface loading rate is very great.
