摘　　要：固-液水力旋流器的入口结构是流体进入旋流器的重要通道,起促使流体在旋流腔内快速形成稳定的流场的作用。水力旋流器的入口结构很大程度上决定着固-液水力旋流器的分离和使用性能。依据对石膏水力旋流器入口区域流态的研究,设计了一定螺距的阿基米德螺旋线式的渐缩入口结构。对比实验证实相比较直切式入口结构,阿基米德螺旋线式入口结构的处理能力提高了6.87%,分离效率提高了2.84%。As the most important passage for liquid to enter the separator,the entrance of solid-liquid separation hydrocyclone is used to form steady field quickly in the vortex chamber.The structure of the entrance decides the separation and using performance of solid-liquid separation hydrocyclone in the very great degree.Based on the flow pattern of the gypsum hydro-cyclone＇s entrance areas,Archimedean helix entrance structure which is in a certain pitch was designed.The contrast experiment showed that compared with straight cut type entrance structure,the processing capacity and separation efficiency of Archimedean helix entrance structure improved 6.87% and 2.84%.
