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混凝土配合比设计、物料平衡计算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-fuzhou 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 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 service life. And so the building of the aggregate yard for the design of closed not only reduces the dust and noise pollution, protected from the weather will gravel moisture content is minimized, also have heat preservation effect, reduce the winter water heating mixing energy consumption. To improve the economic indicators, design project is replaced by using fly ash dosage of cement, to save costs.
