摘　　要：运用CFX方法对具有转动螺纹机筒的单螺杆挤出机的流道进行流场分析,研究分析豆粕在其流道中的运动情况,包括速度矢量图、速度流线图、宏观压力图及挤出量,与具有普通机筒的单螺杆挤出机进行对比分析。结果表明:由于机筒具有反向螺纹及反向转动功能,使流场建压能力增强,挤出性能大幅度提高,速度流线产生涡运动,豆粕充分混合。研究结果可为单螺杆挤出机加工提供理论参考。Using CFX method to analyze material flow field of single screw extruder which with a rotating and spiral barrel,research and analyze the soybean meal movement. Including the velocity vector,velocity flow charts,pressure chart and extrusion capacity. Comparison with a single screw having a common barrel was conducted. The single screw extruder which with a rotating and spiral barrel has reverse thread and turning. It can enhance the ability to build pressure,improve extrusion capacity and produce vortex motion which was conductive to full mix. The research could provide references for the single screw extruder processing.
