叶片螺杆推进器是软体絮状等物料固液分离机上常采用的推进挤压机构，核心零件叶片螺杆采用不锈钢材质，具有齿宽、壁薄等特点，其加工方法不同于圆柱曲面螺旋槽的加工，而是先采用某种成形工艺制作螺旋叶片，之后通过在轴上依次焊接叶片而制成，试验设备中的叶片螺杆圆柱部分下料采用三角形法计算，变截面部分则通过推导展开图外圈的极径方程，并利用绘图软件中的公式曲线作图来实现．

Blade screw propeller is used as the pushing and squeezing machine that is often used in the solid-liquid separa- tor for software materials. The core parts of blade screw are stainless steel material with wide tooth, thin wall and other characteristics, and its processing method is different from the cylindrical surface spiral groove processing. Usually,its ma- chining process is based on a certain forming technology to produce spiral leaf firstly, then welding leaves on the shaft. The cylindrical blade screw in test equipment adopts triangle method to calculate the blank dimensions. Variable cross section of the outer ring graph is realized by using the polar radius equation drawing in the drawing software.
