摘要
在机械混合机理的研究基础上,分析了叶轮转速和装料率对肥料颗粒混合度的影响,并对螺带式混合器和锚式混合器的混合特点进行了分析。通过研究不同混合叶片的相互作用,提出了螺带-螺杆组合叶轮、锚-螺杆组合叶轮和内-外直叶片组合叶轮的多叶轮设计方案。实践表明,在低转速情况下,多叶轮的混合特性与单一叶片相比有明显的提高,同时,内-外直叶片组合叶轮容易加工,具有较广的的混合适应性,满足了简易混合装置的设计要求,可以在复混肥料的生产中得到有效应用。
Based on the mechanical mixing principle, the influence of impeller speed and pouring-rate of manure in mixer on the mixedness is analyzed, and mixing characters of ribbon mixer and anchor mixer are investigated. Considering the interaction of different impellers, the ribbon -screw multi-impeller, anchor- screw multi- impeller and inside-outside straight blades of multi-impeller are proposed. With practice, multi-impeller is shown to be more efficient than single impeller at slow speeds, and there are some typical merits of inside-outside straight blades of multi-impeller. It can been easily manufactured with wide applicability, which is suitbale for the simple mixing equipment design and practical in manure production.
