摘　　要：为了研究带导流筒连续式搅拌槽的固液混合性能,通过建立其计算流体力学模型,采用正交试验方法,选取L_( 9)(3^(4))正交表得到9组方案,通过极差综合分析,确定最优组合方案。试验结果表明:影响浓度标准差的主次因素依次为导流筒位置、直径和高度;影响混合时间的主次因素依次为导流筒直径、高度和位置;影响搅拌桨功率的主次因素依次为导流筒位置、直径和高度;综合考虑的最优组合为导流筒位置为15 mm、高度为50 mm、直径为90 mm,该结论与仿真结果相吻合。In order to study the solid-liquid mixing performance of the continuous stirring tank with diversion drum,by establishing its computational fluid dynamics model,using the orthogonal test method,9 sets of schemes were obtained by selecting theL_( 9)(3^(4))orthogonal table,and the optimal combination scheme was finally determined through the comprehensive analysis of the range.The results showed that the main and secondary factors affecting the concentration standard deviation were the position,diameter and height of the guide drum;the primary and secondary factors affecting the mixing time are the diameter,height and position of the guide tube;and the primary and secondary factors affecting the power of the agitator are the position,diameter and height of the guide tube.The optimal combination considered comprehensively is that the position of the guide tube is 15 mm,the height is 50 mm,and the diameter is 90 mm,which is consistent with the simulation results.
