摘要:以木屑、氯化镁、氧化镁、卤水为搅拌原料,以聚氯乙烯树脂粉、尿素为添加剂,研究立轴行星式搅拌机叶片安装角度、搅拌轴转速对搅拌效果的影响,采用离散元分析软件模拟仿真混合物料搅拌过程,研究叶片不同安装角度、搅拌轴不同转速情况下的物料混合效果;对比分析同等情况下氯化镁颗粒的离散系数大小,确定搅拌的最优参数;对生产的木质板材进行力学性能验证。结果表明:立轴行星式搅拌机叶片的安装角度为45°、搅拌轴转速为30 r/min时搅拌效果最佳。

Abstract:Using sawdust, magnesium chloride, magnesium oxide and brine as stirring raw materials, and polyvinyl chloride tree powder and urea as additives, the influence of the installation angle of the vertical shaft planetary mixer blade and the speed of the stirring shaft on the mixing quality was studied.The EDEM software was used to simulate mixing process of mixed materials and the mixing quality of materials under different blade installation angles and stirring shaft rotation speeds were studied. By comparing and analyzing the discrete coefficient of magnesium chloride particles under the same conditions, the optimal stirring parameters were determined. The mechanical properties of the wooden plates were verified. The results show that the optimal mixing quality is the best when the blade installation angle of the vertical shaft planetary mixer is 45° and the stirring shaft speed is 30 r/min.

Keywords:vertical shaft planetary mixer; discrete element method; blade installation angle; rotating speed of stirring shaft; discrete coefficient
