1、 I 摘要摘要 本次设计课题为京福高铁合肥段箱梁制品厂混凝土搅拌站工艺设计。在设计 中，京福高铁合肥段箱梁制品厂混凝土搅拌站的工艺设计工作主要有以下几点：混 凝土配合比设计、物料平衡计算、混凝土搅拌站设备选型计算和主机生产能量平衡 计算、混凝土搅拌站工艺流程图及混凝土搅拌楼工艺布置图设计。 本次设计的主要宗旨是高效、节能、环保等特点。为适应高速铁路用混凝土对 特别均质和高性能、高强度的要求，采用双卧轴强制式搅拌机。其结构紧凑、运转 平稳高效的减速机构使得搅拌更激烈、更均匀、更迅速；独特的轴端密封机构保证 了可靠性及较长的使用寿命。而且所以设计的骨料堆场为全封闭式，它的建成不仅 降低了粉尘与噪音
2、污染，将沙石含水率受天气影响降到最低，同时还起到保温作 用，降低了由于冬季搅拌水加热的能源消耗。 为提高工程的经济性指标，设计中还采用粉煤灰取代水泥用量，以节约成本。 关键字：关键字： 混凝土 搅拌站 搅拌机 配料 II Abstract My task is Hefei section of beijing-fuzhou high iron box factory concrete mixing station process design.In this design,I mainly do the following work for hefei section of beijing-f
3、uzhou high iron box factory concrete mixing station process design : concrete proportion design, material balance calculation, concrete mixing station equipment selection calculation and host to produce energy equilibrium calculation, concrete mixing process flow diagram and concrete mixing building
4、 process layout design. The design of the main purpose is efficient, energy saving, environmental protection, etc. In order to adapt to the high-speed railway for special with concrete homogeneous and high performance, high strength requirement, we adopt dual-axial mixing machine. Its compact structure, smooth operation efficiency of the deceleration structure makes more intense, stir more homogeneous and more quickly. Unique shaft sealing institutions guarantee the reliability and long servic
