摘　　要：设计SLK型选粉机分级室壳体倾角结构,应用CFD技术对SLK型选粉机分级室导流角度和控制最佳气流速度进行数值模拟,探索分级室壳体倾斜角的最优参数,通过SLK型选粉机实验验证,结果表明其分级效率和分级精度都有明显提高。Classifier housing oblique structure of SLK classifier is designed. Fluid guidance obliquity angle of classifier housing of SLK classifier and controlling of finest air velocity is simulated by CFD technique, to study on the finest parameters of shell obliquity of classifier housing. The results show that the classifying precision and efficiency of the classifier are all improved through experimentation verification of SLK classifier.
