【摘要】 转子型气力分级机是近几年来在我国发展较快的超细分级机,它利用强大的离心力作用能分级出超细的产品,其设计和制造都适合我国的实际国情。该类分级机的主要部件是分级机转子,转子的结构形式是影响分级机分级效果的主要因素。本文通过对转子叶片间流场的数值模拟研究,得到了叶片间距越小其间流场越有利于超细分级的结论,并通过转速、风量和浓度试验对该结果进行了验证,验证结果与模拟结果完全一致,证明了模拟结果的正确性。更多还原

【Abstract】 The vane classifier is the major type of ultra-fine classification equipment. Ultra-fine products are made by the strong centrifugal force. This type of classifier is very suitable to the situation of our country. The classifier consists of a rotating vane. The structure of the vane is very important to the efficiency of the classifier. This paper gains the conclusion that the smaller space between blades is beneficial to the classification effect by simulation of different vane shapes. The simulation result was verified by verifying experiment like rotated speed, gas flow rate and particle concentration.更多还原
