| 摘 要： | 通过研究筒式筛网上固相颗粒的运移规律 ,可为筒式筛网振动筛的动力学参数选择和结构设计提供指导。根据筒式筛网非淹没区固相运移的实际情况 ,在拟流体假设基础上 ,建立了固相运移颗粒群模型 ,并给出了模型求解方法。在筒式筛网筛筒转速n =8 6r/min下 ,得到颗粒群的平均运移速度试验值为 0 0 90 17m/s ,而其计算值为 0 110 6m/s,表明试验装置的计算结果与试验结果能够吻合。提出的颗粒群运移模型对筒式筛网振动筛的进一步研究具有较大的参考价值。

| Abstract: | The study on solid conveyance regular pattern of roller screen can guide the selection of dynamics parameters and design of structure of shale shaker with this kind of screen. Based on the real solid conveyance on non-submerging roller screen and assuming the granule group as pseudo-fluids, the conveyance model of wet granule group on the non-submerging screen is established and the calculating method of this model is given. Under the lower angular velocity of roller screen, the calculating result of experiment unit can be identical to the testing result. The solid conveyance model of granule group is significant to the further study of this kind of shale shaker. |
