逆流干燥机扫仓搅龙运动参数研究

扫仓搅龙的运动参数，尤其是公转速度，直接影响逆流干燥机的工作性能。此前只能通过样机反复试验进行参数修改，才能获得比较满意的结果。文中通过对扫仓搅龙进行运动学和力学分析，推导出扫仓搅龙公转速度的表达式，从而在烘干机的设计阶段即可知道合理的扫仓搅龙公转速度值。应用结果表明，研究结论完全符合实际要求。

Study of Movement Parameters of Sweep Auger of Counter-flow Drier

The performance of the counter-flow drier is effected seriously by the kinematic parameters of the sweep auger, especially the revolution speed. The kinematics and dynamics analyses of the auger were carried out, and the expression of the revolution speed of the auger was developed. Therefore, the rational values of the revolution speed can be obtained in the stage of drier design. The test results showed that the practical requirements can be met by the optimal parameters of the auger.
