摘要
搅拌设备的设计除应保证工艺要求外,以较小功率消耗达到搅拌目的亦是设计目标之一。搅拌器功率计算一方面解决了需要向搅拌介质提供多少功率问题,以便有效地选择电机;另一方面为搅拌器强度计算提供依据,以保证桨叶、搅拌轴的强度。因而,搅拌器功率计算是搅拌器设计中必不可少的步骤。然而搅拌器功率计算却非常繁琐。将Rushton图算法中算图曲线数据进行人工采集,利用仿射变换对采集的数据进行了修正,最后利用B样条曲线对Rushton算图参数化插值,并利用Rushton图算法与永田进治公式法的互补特性,完成了对常规叶片形状的搅拌器功率计算程序化,以达到减小搅拌器功率计算的工作量的目的。
The design of stirring equipment should not only guarantee the technological requirements,but also achieve a less power consumption to meet the stirring goals. The agitator power calculation has solved the problem of how much power need to provide to the mixing medium,so as to select the motor effectively; on the other hand,the basis is provided for the stirrer strength calculation,to ensure strength of the blade and the stirring shaft. Therefore,stirring power calculation is essential in the design process. However the agitator stirring power calculation is very complicated. The nomogram curve data of Rushton graph algorithm are artificially collected,then the collected data are corrected by affine transformation,and finally are parameterized and interpolated by the B-spline curve. Due to the complementary characteristics of Rushton graph algorithm and Nagata Shinji formula method,the mixing power on conventional vane shape is programmed to lessen the design workload.
