Abstract

The purpose of the paper is to further improve the mixing uniformity of concrete aggregates, thereby improving the quality and mixing efficiency of concrete. Taking the structure of a planetary concrete mixer produced by a company as a reference, the discrete element software EDEM was adopted to simulate the material mixing process and to analyse the mixing uniformity. It is found in the simulation that the aggregates at the side wall of the mixing tank are not mixed evenly when the shape of the side scraper of the mixer is modified from a flat surface to a curved surface. The results show that the structural optimisation makes the trajectory of the aggregates more complicated and improves the mixing quality, the mixing uniformity of the three aggregates being increased by 16%, 10.1%, and 22.1%, respectively. The simulation results of the discrete element can provide reference for actual product design.
基于EDEM的行星式混凝土搅拌机关键结构优化设计
本文的目的是进一步提高混凝土骨料的搅拌均匀性,从而提高混凝土的质量和搅拌效率。以某公司生产的行星式混凝土搅拌机的结构为参考,采用离散元软件EDEM对材料搅拌过程进行了模拟,并对搅拌均匀性进行了分析。在模拟中发现,当搅拌机侧刮刀的形状从平面改为曲面时,搅拌槽侧壁的骨料混合不均匀。结果表明,结构优化使集料的轨迹更加复杂,提高了混合质量,三种集料的混合均匀性分别提高了16%、10.1%和22.1%。离散单元的仿真结果可为实际产品设计提供参考。
