摘要
垂直螺旋输送机在依靠离心力和螺旋叶片的摩擦力输送物料的同时,高速旋转的螺旋叶片产生的空气动力作用也促进了物料颗粒的输送,输送机内物料的密度分布很复杂。垂直螺旋输送机内输送物料的流动可视为非牛顿流体流动,用FLUENT流体工程仿真软件模拟水泥在垂直螺旋输送机内输送时的流动状态,并对其运动密度进行了描述和分析。
The vertical screw conveyor conveys materials by the centrifugal force and the friction force of the spiral blade,the aerodynamics produced by the spiral blades rotating at high speed also promote the conveying of material particles,so that the density distribution of materials inside the conveyor is very complicated.The flow of materials conveyed in the vertical screw conveyor can be viewed as non-Newtonian fluid flow.FLUENT fluid engineering simulation software is used to simulate the flow pattern of cement in the vertical screw conveyor,and its kinematic density is described and analyzed.
