摘要
螺旋式固液分离机是参考国外技术国内生产的一种新型固液分离设备,它具有结构简单、能耗低、分离效果好、占地面积小等优点,在农业有机废弃物分离中具有广泛的应用前景。但是大多数固液分离机的螺旋轴采用等轴径、等螺距结构,影响固液分离机的工作效率。文章根据物料在固液分离不同阶段的摩擦特性和体积压缩试验,得出适应物料特性的螺旋倾角和螺旋轴直径参数,设计出变轴径变螺距变螺旋倾角的旋转轴,为螺旋压榨固液分离机的改进提供理论依据。
Screw-type solid-liquid separator is a new solid-liquid separation equipment reference to foreign technology in domestic production.It has a simple structure,low energy consumption,good separation,small footprint,etc.,with a wide range of applications in agricultural organic waste separation.But most of solid-liquid separator are equal to the shaft diameter,the pitch,affecting the efficiency of solid-liquid separator.According to the separated materials at different stages of the friction characteristics and the volume compression experiments,drawing the spiral angle adapting to the material properties and screw shaft diameter parameters,designing the adjustable variable diameter,pitch and spiral angle of the rotation shaft,thereby providing a basis to the improvement of screw press solidliquid separator.
