摘要：根据科研设计要求，设计一套预混合加料装置来完成一条复合材料混合自动生产线的前期建立。通过合理地设计加料机构，采用电子配料秤实现自动配重，按时间要求合理控制加料时间、加料量。通过大量研究分析桨叶形式对于搅拌效率的影响，根据介质类型、要求搅拌出料时间等合理设计桨叶形式以优化效率并通过实验分析验证其可行性，最终证明在获得相近的搅拌混合效果的前提下，选择双层桨式搅拌器（折叶）更省功；配备挡板后可形成稳定的湍流，获得更佳的混合效果。通过合理的工艺计算和设计，完善预混合加料装置的结构、布局，使之符合工艺要求。29853

The Design of Premixing Charging Device
Abstract：According to research and design requirements, designing a set of premixing charging device to help to pre-establish a hybrid composite automatic production line.
Counting the weight automatically through rational design of the feeding mechanism and the use of electronic automatic batching scales. Controlling the feeding time, feeding quantity reasonably according to the time requirement. Analyzing the effects of the blade shape to the mixing and stirring efficiency through a lot of research. Designing the blade shape reasonably according to the media type, the requirement of the time of stirring and discharging in order to optimize efficiency. Then analyzing and verifying its feasibility through experiment. Eventually it proves that to obtain the corresponding effect under the premise of mixing, choose double paddle mixer (folding leaves) saves more power. Equipping with baffle can form stable turbulence, obtain better mixing effect. Through rational calculation and design process, improving the pre-mixed feed device’s structure and layout to meet the technical requirements.
Keywords：Premixing charging device；Automatic counterweight；The blade shape；Mixing efficiency
