螺旋输送机总体设计

I摘要随着社会机械行业的发展，我国螺旋输送机逐渐向机构简单，操作方便方向发展，机体密封结构能有效地防止粉尘污环境。主要用于火力发电厂的煤粉系统，对冶金、化工、建材、轻工等系统也广为利用，工程实际中较常用的为固定式、水平慢速螺旋输送机。主要特点是：结构简单、外形尺寸小、造价低、密封性好、可实现多点进卸料、对物料有搅拌混合作用，操作安全、方便，制造成本低。但其输送距离小，叶片和机壳易磨损，能耗较高，对物料破碎作用较强。GX型螺旋输送机是我国最早定型生产的通用性生产设备。本文论述了螺旋输送机的现状和发展及其设计理论和方法。在过去的20年里，我国机械运输部门完成了一些标志性的研究与开发工作，应用这些成果所制造的装备基本满足了工业的需求，其中应用计算机能使模型、测量和理论相互检验。本设计为未来输送机的将向着大型化发展、扩大使用范围、物料自动分拣、降低能量消耗、减少污染等方面发展提供理论依据。大型化包括大输送能力、大单机长度和大输送倾角等几个方面。长距离、大运量连续输送物料的更完善的输送机结构。若用于生产将扩大输送机的使用范围，发展到能在高温、低温条件下有腐蚀性、放射性、易燃性物质的环境中工作，以及能输送炽热、易爆、易结团、粘性物料的输送机。也为生产提供一定的参考。。关键词：螺旋输送机；叶片；机壳；物料搬运IIAbstractWiththedevelopmentofsocialmachineryindustry，Graduallytotheinstitutionsofourscrewconveyorissimple,user-friendlydirection，Thestructureofthebodycaneffectivelysealedtopreventdustpollutionenvironment。Mainlyusedincoal-firedpowerplantsofthepulverizedcoalsystem，Metallurgical,chemical,buildingmaterials,lightindustryandothersystemsarealsowidelyuse，Morecommonlyusedinengineeringpracticeforthefixed,horizontalscrewconveyorslow。Themaincharacteristics：Simplestructure,smallsize,lowcostandgoodsealingperformance,enablingmulti-pointdischargeintothemixingmixingmaterials，Operationalsafety,convenience,lowcostmanufacturing。However,itstransmissionfromthesmall,easytowearandtearleavesandchassis,highpowerconsumption,theroleofastrongmaterialbroken。GX-typescrewconveyorstereotypesofChina'sfirstgeneral-purposeproductionofproductionequipment.Thisarticlediscussesthecurrentstatusanddevelopmentofscrewconveyoranditsdesigntheoryandmethods.Inthepast20years,China'smachinerytocompletethetransportsectoranumberoflandmarkresearchanddevelopmentwork,theapplicationoftheseresultsbyequipmentmanufacturerstomeetthebasicneedsoftheindustry,whichenablestheapplicationofcomputermodels,measurementandtheoryofmutualinspection.Theconveyordesignforthefuturewillbetowardthedevelopmentoflarge-scale,expandingtheuseofthescopeofautomaticsortingofmaterialstoreduceenergyconsumption,reducepollutionandprovideatheoreticalbasistodevelop.Includinglarge-scaletransmissioncapacity,largesingle-lengthandinclinationofseveralaspectsoftransportation.IIILong-distance,largecapacityfordeliveryofmaterialstoimprovetheconveyorstructure.Ifusedintheproductionwillexpandtheuseofconveyortodevelopinthehigh-temperature,lowtemperatureconditions,corrosive,radioactive,flammablesubstancesintheenvironment,aswellastotransporthotandexplosive,easytoknotgroups,viscousmaterialtheconveyor.Aswellastoprovideareferenceforproduction.Keywords:Screwconveyor；blades；cases；materialhandlingIV摘要....................................................................................................IAbstract..............................................................................................II第1章螺旋输送机............................................................................11.1概述...........................................................................................................11.2输送机的安装...........................................................................................6第2章.螺旋输送机总体设计方案的选择........................................92.1设计要求..................................................................................................92.2螺旋输送机的总体设计简图..................................................................92.3GX型螺旋输送机的计算.........................................错误!未定义书签。2.3.1螺旋直径及螺旋轴转速的计算......................................错误!未定义书签。2.3.2螺旋轴转速的计算.........................................................错误!未定义书签。2.3.3功率计算.........................................................................错误!未定义书签。2.4LS型螺旋输送机的计算..........................................错误!未定义书签。2.4.1螺旋输送机的输送能力.................................................错误!未定义书签。2.4.2螺旋输送机的转速.........................................................错误!未定义书签。2.4.3螺旋输送机的功率计算.................................................错误!未定义书签。2.5螺旋输送机的选型...................................................错误!未定义书签。第3章螺旋叶片的设计....................................错误!未定义书签。3.1螺旋叶片的分类.......................................................错误!未定义书签。3.2螺旋输送机叶片的原理：.......................................错误!未定义书签。3.3螺旋叶片的设计计算：...........................................错误!未定义书签。3.4螺旋叶片耐磨性的措施..........................................错误!未定义书签。3.5螺旋叶片的下料.......................................................错误!未定义书签。3.6叶片的成形加工.......................................................错误!未定义书签。第4章螺旋轴的设计........................................错误!未定义书签。4.1螺旋轴的受力分析...................................................错误!未定义书签。V4.2曲刚度条件设计螺旋轴...........................................错误!未定义书签。4.2.1螺旋轴的计算.................................................................错误!未定义书签。4.2.2螺旋轴尺寸确定.............................................................错误!未定义书签。4.2.3轴的力校核.....................................................................错误!未定义书签。第5章螺旋输送机进出料口及底座的设计...错误!未定义书签。5.1进出料口...................................................................错误!未定义书签。5.2底座..........................................................................
