I椭球布料盘催化剂密相装填成套装置设计摘要：国内外颗粒物料的装填，尤其是催化剂颗粒的装填工作，在其相关的领域越来越受到重视。本课题设计了一种利用颗粒物料在旋转的椭球型布料盘中通过离心力作用将颗粒物料从布料盘的开口中均匀的抛洒出去，从而达到物料均匀、密相装填效果的一种装置。设计按照JB/4735-1997钢制焊接常压容器进行设计、制造、检验和验收。装置的材料选用9i18rNOC：工作压力为常压，工作温度为常温。装填的物料为32lOA，物料密度为3/g3600MK。设计说明书中进行了设备材料的选择，运转功率的计算，布料盘的强度校核和开口槽对数螺旋线的说明与应用，主轴的计算，齿轮和轴承的选取和校核，电机的选取及耳式支座的选取，绘制了设计装置的总装配图及相关零件图。本设计装置主要应用于化工、石油化工和生物制药等行业的颗粒物料密相装填。关键词：密相装填；布料盘；设计；IIthedesignofcompletesetsofequipmentofcatalystdenseloadinginellipsoidThrowingparticlemachineAbstract：Domesticandforeignparticlematerialsloading，especiallythecatalystsbackmixhandloadingwork，intherelevantfieldgetmoreandmoreattention.Inordertoachievethedesiredeffectwithuniformmaterialanddenseloading,thesubjectdesignedadevicewhichs-hedsevenlygranularmatertalsfromtheopeningofThrowingparticlemachinebycentrifugalforcewithinrotationalellipsoidThrowingparticlemachine.DesignaccordingtoJB/4735-19-97Steelweldedatmosphericpressurevesselsdesign、manufacture、inspectionandac-ceptance.Deviceofmaterialselectionis9i18rNOC；workingpressureisordinarypressure,workingtemperatureisNormaltemperature.loadingmaterialsis32lOA,materialdensityis3/g3600MK.Designspecificationshaveequipmentmaterialselection,calculatingthepowerofoperation,strengthcheckofThrowingparticlemachine.Instructionsandapplicationoflogarithmicspiral,axiscalculation,selectionandcheckofGearandbearing,motorselectionandtheselectionofeartypesupport.Mappedthegeneralassemblydrawingsandrelatedpartsdrawing.Thisdesigndeviceismainlyusedinchemicalindustry,petrochemicalindustryandbiopharmaceuticalindustries.Keywords：denseloading；Throwingparticlemachine；designIII目录摘要···········································································································································目录···········································································································································术语表·······································································································································1绪论·······································································································································11.1概述····································································································································11.2颗粒密相装填的研究的意义，国内外研究现状和发展趋势········································11.2.1课题研究意义················································································································11.2.2国内外的现状················································································································11.3颗粒密相装填的研究目标和关键问题············································································51.3.1研究目标························································································································5IV1.3.2解决关键问题················································································································51.4颗粒密相填装作用和行业应用························································································52设计参数的选取和设计思路·······························································································62.1设计参数····························································································································62.2设计思路····························································································································62.3设计内容与具体步骤········································································································63结构的设计和分析···············································································································73.1总体结构设计····················································································································73.2材料的选取························································································································73.3布料盘计算或校核············································································································9V3.3.1布料盘的选取和强度计算·····························································································93.3.2布料盘上对数螺旋线开口槽························································································103.3.2.1对数螺旋线的来源·····································································································103.3.2.2对数螺旋线方程·········································································································103.3.2.3对数螺旋线应用·········································································································123.3.2.4总结·····························································································································133.3.3布料盘开口槽宽度的设计····························································································143.4电动机的选择···················································································································153.
