摘要/Abstract

摘要： 为了提高压裂混砂搅拌装置的搅拌效果，以混砂搅拌装置混合时间为实验指标，针对搅拌叶轮的结构特点，采用正交实验及CFD数值模拟相结合的方法研究了搅拌叶轮的主要几何尺寸对混合时间的影响规律，得到了搅拌装置叶轮最佳结构参数，为搅拌叶轮结构优化设计提供了理论支撑。结果表明，搅拌叶轮的几何尺寸变化对混合时间具有一定的影响，其中，上叶轮直径影响最大，下叶轮直径和下叶轮导流筒与叶轮直径比值次之，上叶轮导流筒与叶轮直径比值影响相对较小；搅拌叶轮几何尺寸最优方案对应的混合时间最短，值为11.0 s。

Abstract: To improve the mixing performance of fracturing sand mixing device, a method that combines the orthogonal test and CFD numerical simulation was adopted to study the influence of primary geometric dimensions of mixing impellers on mixing time. The mixing time was used as the experimental index, and the structural features of mixing impellers were considered. The optimal structural parameters of the impellers of mixing devices were obtained, providing theoretical support for the structural optimization of the mixing impellers. The results showed that the variation of the geometric dimensions of mixing impellers influenced the mixing time. The diameter of the upper impeller had the greatest influence, followed by the diameter of the lower impeller as well as the diameter ratio between the lower draft tube to the lower impeller, whereas the diameter ratio between the upper draft tube to the upper impeller had a relatively minor influence. The optimal configuration for the geometric dimensions of mixing impellers yielded the shortest mixing time of 11.0 s.

Key words: fracturing, sand mixing, mixing device, mixing impeller, mixing time
