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：混凝土搅拌站搅拌机配料AbstractMytaskisHefeisectionofbeijing-fuzhouhighironboxfactoryconcretemixingstationprocessdesign.Inthisdesign,Imainlydothefollowingworkforhefeisectionofbeijing-fuzhouhighironboxfactoryconcretemixingstationprocessdesign:concreteproportiondesign,materialbalancecalculation,concretemixingstationequipmentselectioncalculationandhosttoproduceenergyequilibriumcalculation,concretemixingprocessflowdiagramandconcretemixingbuildingprocesslayoutdesign.Thedesignofthemainpurposeisefficient,energysaving,environmentalprotection,etc.Inordertoadapttothehigh-speedrailwayforspecialwithconcretehomogeneousandhighperformance,highstrengthrequirement,weadoptdual-axialmixingmachine.Itscompactstructure,smoothoperationefficiencyofthedecelerationstructuremakesmoreintense,stirmorehomogeneousandmorequickly.Uniqueshaftsealinginstitutionsguaranteethereliabilityandlongservicelife.Andsothebuildingoftheaggregateyardforthedesignofclosednotonlyreducesthedustandnoisepollution,protectedfromtheweatherwillgravelmoisturecontentisminimized,alsohaveheatpreservationeffect,reducethewinterwaterheatingmixingenergyconsumption.Toimprovetheeconomicindicators,designprojectisreplacedbyusingflyashdosageofcement,tosavecosts.Keyword:concretemixingstationmixeringredients目录前言........................................................1第一章混凝土配合比设计...........................................................................41.1设计条件............................................................................................41.2混凝土配合比计算............................................................................4第二章物料平衡计算...................................................................................8第三章混凝土搅拌站生产工艺流程...........................................................9第四章设备选型计算.................................................................................114.1搅拌机的选型计算..........................................................................114.2砂石输送设备选型..........................................................................124.2.1水平带式输送机......................................................................................124.2.2倾斜带式输送机.......................................................................................134.3螺旋输送机的选型计算..................................................................154.4.定量水表的选择计算.....................................................................164.5骨料配料机的选型.........................................................................
