摘要
桨叶是立式捏合机的重要部件,其直接关系到立式捏合机混合效率及混合扭矩。采用CFD方法研究了立式捏合机工艺参数(转速、转动模式)及桨叶结构参数(桨桨间隙)变化对空心桨瞬时扭矩和平均扭矩的影响。研究结果表明,桨叶瞬时扭矩与空心桨和实心桨相对位置有关,桨叶转速只影响桨叶瞬时扭矩值,桨叶平均扭矩与桨叶转速呈线性关系;混合物料为牛顿体流体时,不同转动模式(正转、反转)对桨叶平均扭矩的影响较小。
Blades are the important devices for the twin-blade planetary mixer, which determine the mixing efficiency and the energy consumption. In this paper, CFD simulation was carried out to analyze the effects of technological parameters （ rotating speed, rotating mode） and geometric parameter （blade-blade gap） on the instantaneous and average torque of the hollow blade for the twin-blade planetary mixer. The results revealed that the instantaneous torque of blades is dependent on the relative position of the plain and hollow blades, where the rotating speed only affects the magnitude of the instantaneous torque. The average torque of blades shows a linear relation with the rotating speed.When the mixing material is Newtonian fluid,the rotating mode （co-rotating mode ,counter-rotating mode） has little effect on the magnitude of the average torque.
