摘要:

针对双螺旋输送机输送及内部受力问题,基于离散单元法,借助离散元分析软件EDEM,根据Hertz接触理论,建立了物料颗粒与颗粒之间、颗粒与装置之间的接触模型;在物理与几何参数不同的情况下,分析了双螺旋输送机对物料颗粒输送特性的影响。结果表明,颗粒在双螺旋输送机内的运动以直线运动为主,周向运动为辅;改变轴距对双螺旋输送机物料输送特性影响较大,随着轴距的增大,双螺旋输送机质量流速逐渐增大,中心区域颗粒受力逐渐减小。

关键词: 双螺旋输送机, 质量流速, EDEM软件, 输送特性

Abstract:

Based on the discrete element method, the transport and internal force problem of the double screw conveyor was studied by using the discrete element analysis EDEM software. According to the Hertz contact theory, the contact models of material particles and devices were established, and the influence of the double screw conveyor on the transportation characteristics of the material particles under different physical and geometric parameters was analyzed.The results show that the movement of particles in the conveyor is mainly in a straight line, with the circumferential movement as the auxiliary; the change of the wheelbase has a great influence on the material conveying characteristics of the conveyor. With the increase of the wheelbase, the mass flow rate increases gradually, and the particle force in the central area decreases gradually.

Key words: Double screw conveyor, Mass flow rate, EDEM software, Conveying characteristics
