摘要
通过优化转运站的结构设计参数,使带式输送机转运站不堵料,减小冲击和磨损,减少粉尘污染。利用离散元软件EDEM对带式输送机转运站进行了数值模拟。选取煤作为仿真材料,对转运站的全程物料仿真表明,抛物线形的头罩与弧线形溜槽,能够很好地引导物料流,控制磨损与冲击。头罩的冲击角度应小于20°,溜槽的倾角应大于等量摩擦角一定范围。本项目投入实际工程应用证明转运站运行状况良好,基本达到设计初期目的。证明了利用EDEM离散元软件对转运站设计的可行性和准确性。
The structural design parameters for the forwarding station are optimized to keep the forwarding station of the belt conveyer from blockage and to minimize impact and wear,powder pollution. Numerical simulation is performed for the forwarding station of the belt conveyer using the discrete element software EDEM. With the coal as the simulation material,it＇s shown from whole-course material simulation at the forwarding station that the parabola-shaped hood and arc chute can be used to well guide the material flow and control wear and impact. The impact angle of the hood shall be less than20°,chute inclination shall be greater than certain range of equivalent frictional angle. It＇s indicated through actual engineering application that the forwarding station is in good condition and nearly reaches the initial design purpose. The study proves design feasibility and accurateness of the forwarding station using EDEM discrete element software.
