带式输送机毕业设计

洛阳理工学院毕业设计（论文）IQD650气垫带式输送机气室结构设计摘要本次毕业设计是气垫带式输送机气室结构设计。首先对带式输送机做了简单的概述，对气室结构进行了一些了解，并对国内外的气室结构改进进行了了解；接着分析了带式输送机的选型原则及计算方法；然后根据这些设计准则与计算选型方法按照给定参数要求进行选型设计；接着对所选择的输送机各主要零部件进行了校核。气垫带式输送机主要有八部份组成：风机，气室，传动装置，机尾和导回装置，中部机架，拉紧装置以及胶带。气垫带式带式输送机是一种适应能力比较强且应用广泛的输送机械，常用于输送块状和粒状的物料，也可用于输送成件物品。目前，气垫带式输送机正朝着长距离，高速度，低摩擦的方向发展，近年来出现的气垫带式带输送机就是其中一个。在气垫带式输送机的设计与制造以及应用方面，目前我国与国外还有较大差距，国内在设计制造气垫带式带式输送机过程中存在着很多不足。本次带式输送机的设计代表了设计的一般过程，对今后的选型设计工作有一定的参考价值。关键词：气垫带式输送机，气室结构，选型洛阳理工学院毕业设计（论文）IIBELTCONVEYORABSTRACTThegraduationprojectisabouttheplantwithmovingbeltconveyordesign.First,doasimplebeltconveyoroverview;thentheprincipleofselectionofthebeltconveyorandmethodofcalculation;thencalculatedbasedonthesedesigncriteriaandselectionmethodofparametersinaccordancewiththerequirementsofagiventypedesign;wentontotheselectedconveyorwascheckingallmajorcomponents.Therearesixmaincomponentsofcommonbeltconveyorcomponents:transmission,tailandbackintoequipment,centralframe,tensioningdevice,andtape.Beltisarelativelystrongabilitytoadaptandapplyawiderangeoftransportmachinery,usedforbulktransportandgranularmaterialscanalsobeusedtotransportintotheitems.Currently,thebeltconveyorismovinglongdistance,highspeed,lowfrictioninthedirectionoftheaircushioninrecentyearsisoneofthebeltconveyor.Inthebeltconveyordesignandmanufactureandapplication,thecurrentcomparedwithforeignadvancedlevelinChinaisstillawidegapbetweenthedomesticprocessinthedesignandmanufactureofbeltconveyorthereismuchtobedesired.Thebeltconveyordesignrepresentsthegeneralprocessofdesign,selectionofdesignworkforfuturereferencecertainvalue.KEYWORDS：beltconveyor,thetransport,typedesign洛阳理工学院毕业设计（论文）III目录前言................................................................................................1第1章气垫带式输送机的概述.......................................................21.1气垫带式输送机的应用范围.............................................21.2气垫带式输送机的特点和工作原理....................................31.3气垫带式输送机的型式规格...............................................31.4气垫带式输送机的总体规格...............................................41.4.2传动滚筒.....................................................................51.4.3驱动装置...................................................................51.4.4改向滚筒.....................................................................51.4.5托辊.............................................................................51.4.6气室.............................................................................51.4.7拉紧装置.....................................................................51.4.8风机.............................................................................61.4.9清扫器.........................................................................61.4.10卸料装置...................................................................61.4.11制动装置...................................................................61.4.12前置装置...................................................................6第2章设计与计算...........................................................................72.1原始数据及工作条件...........................................................72.2输送带输送量的计算...........................................................72.2.1带速的选择.................................................................72.2.2输送机输送量的计算.................................................72.3圆周驱动力和驱动功率的计算............................................82.3.1输送带张力的计算.....................................................82.3.2最小张力点的校核.....................................................92.4电动机功率的计算.............................................................102.5各种阻力的计算.................................................................102.5.1凸弧段阻力的计算...................................................10洛阳理工学院毕业设计（论文）IV2.5.2凹弧段阻力的计算...................................................112.5.3改向滚筒阻力的计算...............................................122.5.4固定梨式卸料器阻力的计算....................................122.5.5清扫器阻力的计算...................................................122.5.6倒料槽阻力的计算...................................................122.5.7进料口物料加速阻力的计算....................................132.6传动滚筒的计算.................................................................132.7拉紧装置的计算.................................................................132.8风机选型计算.....................................................................132.8.1输送量的计算设计....................................................132.8.2通风机风压的计算....................................................142.8.3通风机风量的计算...................................................152.9气室降压计算.....................................................................172.10风机功率计算...................................................................182.10.1风机轴功率的计算.................................................182.10.2风机消耗功率的计算..............................................182.11带负荷启动校核...............................................................18第3章主要部件的选择.................................................................203.1总体方案的确定...........................
