内蒙古工业大学本科毕业设计说明书摘要本次毕业设计是关于带式输送机和给料装置的设计。粉煤灰中铁粉的运输和存储一直是粉煤灰提取过程比较重要的两个环节,本次设计就是提取铁粉这个流程中的运输和给料装置。运输装置采用水平带式输送机进行运输、给料采用电磁振动给料机进行给料。带式输送机设计包括:带宽、带型、传动滚筒、动力滚筒的形状及尺寸设计,给料装置因为是运输装置的中间装置,所以设计较为简单包括:振动器的选择、振幅指示器、减震弹簧、料斗的形状及尺寸确定。带式输送粉末状物质,那本设计采用槽型托辊进行输送,保证物料不已脱落儿导致影响工作效率。给料机是采用电磁振动给料机,此类给料装置可以较为精确的接近临界共振状态,减少了能源的浪费。本课题的主要成果是设计出传输距离较短的水平带式输送机和电磁振动给料机。关键词:带式输送机传动装置导回装置料斗电磁震动器内蒙古工业大学本科毕业设计说明书AbstractThedesignisagraduationprojectaboutthebeltconveyor.Atotaloftwochapters,thefirstchapterfirstmakesabriefoverviewofbeltconveyor;Thenanalyzedtheprincipleoftypeselectionofbeltconveyorandcalculationmethods;Andthenaccordingtothesedesigncriteriainaccordancewiththerequirementsgivenparameterselectionandcalculationmethodfortypeselectiondesign;Thenthechoiceofconveyormainpartsandcomponentsforthechecking.Ordinarybeltconveyorconsistsofsixmainparts:transmissiondevice,thetailorguidedevice,middleframe,tensiondevice,andadhesivetape.Thesecondchapter,firstofall,theelectromagneticvibrationfeederdidsimplearediscussed;Thenaccordingtothegivenparametersforstructuredesignofthefeeder;Thentheelectromagneticvibratingfeederforelectromagneticsanddynamicsanalysis,mainlythechoiceofthevibrator.Finallycarriesonthesimpleinstallationinstructions.Electromagneticvibratingfeederisanimportantequipmentinproductionlineofflyash,isalsoacorepartsontheproductionline.Butthedomesticexistingelectromagneticvibratingfeederaresmallandmediumsizedmachine,smallpower,lowefficiency,andisnotsuitableforcontinuousconveyinghightemperature,highdust,coke,sodevelopedlargespecialelectromagneticvibratingfeederarekeydeterminantsofdryquenchingproductionlinelocalization,thefuturedevelopmentprospectisverybig.Keywords:thebeltconveyorDriveUnitDeliveryEndHopperElectromagneticvibrator内蒙古工业大学本科毕业设计说明书目录第一章绪论..............................................381.1带式输送机发展概况.................................................................................381.2带式输送机的应用......................................................................................381.3带式输送机的分类......................................................................................381.4各种带式输送机的特点.............................................................................381.5电磁振动给料机的发展状况.....................................................................391.6电磁振动给料机的分类.............................................................................39第二章带式输送机设计......................................412.1带式输送机的工作原理..............................................................................412.2带式输送机主要部件的选型与设计计算..................................................422.2.1带式输送机的原始数据..................................422.2.2带式输送机带速的确定..................................422.2.3带式输送机带宽的计算..................................432.2.4带式输送机输送带的确定................................432.2.4带式输送机输送带强度的验算............................452.3动力滚筒的作用与分类.............................................................................472.3.1动力滚筒直径的确定和滚筒强度的验算....................472.4带式输送机电动机的选择..........................................................................482.4.1运行阻力的计算........................................482.4.2传动功率的计算与电机的选择............................502.5联轴器的的选择.........................................................................................512.5.1联轴器的作用和分类....................................512.5.2联轴器类型的选择......................................522.5.3联轴器的选用计算......................................522.6带式输送机布置方式.................................................................................532.7张紧装置.....................................................................................................542.8改向装置................................................................................................542.9卸料装置...................................................................................................54第三章电磁振动给料机......................................553.1电磁振动给料机的简介.............................................................................553.2电磁振动振动给料机的分类......................................................................553.3电磁振动给料机的构造、原理与选型.....................................................563.3.1给料机料斗尺寸及形状的设计...............................................................573.3.2电磁振动器的减震弹簧的确定...............................................................60内蒙古工业大学本科毕业设计说明书总结.......................................................62参考文献....................................................1致谢........................................................21第一章绪论本章将阐述带式输送机的发展、应用、分类、及特点,电磁振动给料机的发展、分类及特点。1.1带式输送机发展概况带式输送机是煤矿最理想的高效连接运输设备,它与其它运输设备(如机车类)相比,不仅具有长距离、大运量、连续输送等优点,而且运行可靠,易于实现自动化、集中化控制,特别是对高产高效矿井,带式输送机已成为煤炭高效开采机电一体化技术与装备的关键设备。目前,我国煤矿共用带式输送机约120万台,矿用带式机也正在往大运量、长距离、高带速方向发展。1.2带式输送机的应用带式输送机是连续运输机的一种,连续运输机是固定式或运移式起重运输机中主要类型之一,其运输特点是形成装载点到装载点之间的连续物料流,靠连续物料流的整体运动来完成物流从装载点到卸载点的输送。在工业、农业、交通等各企业中,连续运输机是生产过程中组成有节奏的流水作业运输线不可缺少的组成部分。1.3带式输送机的分类带式输送机分类方法有多种,按运输物料的输送带结构可分成两类,一类是普通型带式输送机,这类带式输送机在输送带运输物料的过程中,上带呈槽形,下带呈平形,输送带有托辊托起,输送带外表几何形状均为平面;另外一类是特种结构的带式输送机,各有各的特点.其简介
