摘　　要： 本文根据已有的搅拌器结构和使用方法，提出了一种新型的搅拌器——筒式搅拌器，并利用德国生产的“欧洲之星”系列的IKA EUROSTAR POWER CONTROL实验装置对筒式搅拌器的搅拌功率、混合反应时间和混合效率等性能参数进行了大量的实验研究。通过实验优选出筒式搅拌器所适合的直径比范围、适用的转速范围和介质粘度范围等应用条件，并与推进式和涡轮式搅拌器进行了相应的比较。通过观察实验现象和处理数据得出：搅拌过程中，筒式搅拌器能够形成比传统搅拌器较好的径向流和轴向流；筒式搅拌器径向流的作用使其在大直径的容器中也能有较好的搅拌效果；在同等条件下，筒式搅拌器的搅拌功率比推进式和涡轮式搅拌器略小，但搅拌时间与推进式和涡轮式搅拌器相比，缩短了一半左右，搅拌效率提高一倍。本文的研究结果是在大量的实验基础上获得的，通过对小直径筒式搅拌器性能参数的测量与研究，为今后工业实验和应用提供了参考。本文的研究对于搅拌器的性能参数研究具有重要的参考价值。 According to the structure and application of the existing impellers,this paper proposes a new type of impeller being named cylinder impeller.With an IKA EUROSTAR POWER CONTROL experiment equipment that is made inGermany by European Star, the performance parameters of the cylinderimpeller, such as stirring power, mixing time and mixing efficiency, thefitting diameter extension, stirring speed extension and medium viscosityextension of the cylinder impeller are gained after experiment. It alsomakes a comparison with a propeller and a turbine impeller. By observingthe experiment phenomena and dealing with the data, the conclusions are:in the process of stirring, cylinder impeller can produce better radialand axis flows than traditional impellers, which can take good performancein big vessels. In the same condition, the stirring power of the cylinderimpeller are less than propeller and turbine impeller, but the mixing timeis a half or so and the stirring efficiency is twice of them. The researchof the paper is based on lots of experiments. By measuring and researchingthe performance parameters of a short diameter cylinder impeller, itprovides some experiences for industry experiment and appliance. Inaddition, this paper will play an important role in the research of theperformance parameters of an impeller.
