摘　　要：为了研究多级斜板式水沙分离装置中斜板安装角度的变动对装置的水沙分离效果所产生的影响,对同一流量、不同含沙浓度进行了水沙分离实验。结果表明:流量控制在0.9m3/h左右、含沙浓度在15kg/m3之内时,溢流泥沙颗粒D50随泥沙浓度增大而逐渐减小,装置的分离率就高;当斜板的角度α为45°、β为60°时,装置的水沙分离效果最佳,分离率最高。In order to study the impacts of swash plateangle change of swash plate type multi-stage water and sediment separation device on water and sediment separation device,different sediment concentrations of water and sediment separation experiments were performed with the same flow rate.When the flow control is around 0.9m3/h,and these diment concentration is 15kg/m3,the overflow D50 sediment concentration decreases with increasing separation rate.According to the concentration and levels of oblique overflow settling plates,the water and sediment separation is the best with the highest separation rate with the swash plateangleɑangle at 45°andβangle at 60°.
