筒式网钻井振动筛湿固相颗粒运移模型

Wet Solid Conveyance Model of Shale Shaker with Roller Screen

筒式筛网是近年来提出的一种新型圆筒结构筛网,其工作时除与筛箱一起振动外,同时还绕自身轴线作旋转运动,具有自洁作用,可大大提高筛分效率。通过湿固相颗粒在筒式筛网上的非淹没区受力情况分析,建立了其单颗粒运移模型,提出了筒式筛网湿颗粒的抛掷指数、抛掷运移速度及计算方法。研究结果可指导筒式网振动筛设计和选择。

Roller screen is a new kind of cylinder screen put forward recent years. When working, it vibrates with shaker deck, and slowly rotates with the axes itself, so it can self-clean and improve screening efficiency greatly. Based on the analysis of the force of wet solid on the non-submerging roller screen, the single solid conveyance model is built, and the throwing coefficient, conveyance velocity of non-submerging roller screen and their calculating methods are given. The research results can guide the design and selection of roller screen shale shaker.
