| 目的 针对2种粘稠液体物料混拌后定量灌装充填的机械设备，设计使混合效果更加快速和均匀的搅拌桨结构。方法 应用有限元方法分析灌装到混拌器中的流体物料三维流场特性，研究不同搅拌桨对相应物料推送、搅拌和灌装的影响。比较各种工况下的连续速度场、压力场、混合效果。结果 桨叶的搅拌运动使物料在较短时间内快速均匀混合。轴向错列向前倾斜的推进式桨叶对流体具有混合作用，同时增加输送能力，减低内部流体的压力，降低工艺和结构设计的复杂程度。实测结果验证了模拟计算的合理性。结论 获得了搅拌桨优化设计结果预测的有效方法。该研究成果能为小型粘性物料灌装混拌机升级换代提供理论依据和参考。 |

| The work aims to design the structure of mixing paddle to make the mixing effect faster and more uniform in view of the machinery equipment for quantitative filling of two viscous liquid materials after mixing. The finite element method was used to analyze the three-dimensional flow field characteristics of the fluid materials filled into the mixer and study the effects of different mixing paddles on the pushing, mixing and filling of the corresponding materials. Then, the continuous speed field, pressure field and mixing effect under various working conditions were compared. The stirring motion of the paddle made the materials mix quickly and evenly in a short time. The axially staggered forward-inclined propelling paddle not only mixed the fluid, but also increased the transport capacity and reduced fluid internal pressure, which reduced the complexity of process and structural design. An effective method for predicting the optimal design result of stirring paddle is obtained. The research results provide a theoretical basis and reference for the upgrading of small viscous material filling and mixing machine. |
