埋刮板輸送機是一種在封閉的矩形斷麵的殼體內，借助於運動著的刮板鏈條連續輸送粉狀、顆粒狀及小塊狀等散粒物料的輸送設備。它主要由封閉的殼體、刮板鏈條、驅動裝置及張緊裝置等部件組成。與螺旋輸送機和鬥式提升機相比，它具有結構簡單、重量輕、體積小、密封性能好、安裝維修方便、運行平穩、操作易實現自動控製、能多點加料和卸料等優點，生產使用中又以其節約空間、改善工人的操作條件和防止環境汙染等特性而廣泛應用於化工、冶金、機械、輕工、電站等部門的設備配套，可輸送揚塵大、有毒、易燃和高溫物料。2010年11yueanhuimouhuagongchangguolupeitaoshebeizhong，lengzhajichuliaokoudemaiguabanshusongjichuxianguzhang，wuliaozaiqixiangtineiduijibingdaozhishusonglianduociduanlian，yanzhongyingxianglelengzhajidechuliao。weixiuhoushebeizhengchangyunxingdeshijianjiaoduan，yincigaihuagongchangzanshicaiyongdaishishusongjishusongluzha，daozhixianchanghuanjingwuranjiaoda。benwenzhenduigaixingshishusongjideyunxingquexianjinxingfenxi，bingduigailengzhajichuliaokoumaiguabanshusongjidehelishejijinxingchanshu，keweiguolupeitaoshebei——冷渣機出料口埋刮板輸送機的優化設計提供參考。

2、故障分析
原埋刮板輸送機由尾部、加料段、水平中間段、彎曲段、傾斜角度段、頭部、傳動裝置等部件組成，其中彎曲段有一個導鏈裝置。從整體上分析，原設計僅僅是將無傾角的MS型埋刮板輸送機在中間加一個彎曲段而構成，對於該物料這樣的設計存在較大的不合理性。
2.1鏈條選用不合理

2.2刮板選用不合理
原設計刮板為T型內向式刮板，結構簡單。該物料為自由流動的物料，在傾斜輸送的情況下其流動性更好。因此，在傾斜角度為24°的de情qing況kuang下xia，為wei了le保bao證zheng料liao層ceng間jian的de穩wen定ding性xing及ji增zeng大da摩mo擦ca力li，一yi般ban選xuan用yong形xing狀zhuang較jiao複fu雜za的de刮gua板ban。原yuan設she計ji結jie構gou簡jian單dan，運yun行xing時shi雖sui鏈lian條tiao水shui平ping段duan完wan全quan能neng帶dai走zou物wu料liao，進jin入ru傾qing斜xie段duan後hou在zai接jie近jin休xiu止zhi角jiao傾qing角jiao下xia物wu料liao必bi然ran大da量liang回hui流liu，效xiao率lv大da大da降jiang低di，回hui流liu物wu料liao堆dui積ji於yu彎wan曲qu段duan，增zeng加jia刮gua板ban鏈lian條tiao的de磨mo損sun及ji動dong力li的de消xiao耗hao。物wu料liao堆dui積ji到dao一yi定ding程cheng度du後hou，不bu但dan鏈lian條tiao磨mo損sun嚴yan重zhong，同tong時shi電dian流liu上shang升sheng，刮gua板ban也ye在zai彎wan曲qu段duan變bian形xing。雖sui然ran彎wan曲qu段duan設she有you一yi個ge導dao鏈lian裝zhuang置zhi，但dan是shi間jian隙xi大da，刮gua板ban磨mo損sun快kuai，浮fu鏈lian現xian象xiang也ye並bing沒mei有you得de到dao遏e製zhi。一yi般ban情qing況kuang下xia鏈lian條tiao浮fu鏈lian傾qing向xiang雖sui然ran不bu是shi很hen大da，但dan對dui料liao流liu的de影ying響xiang卻que很hen大da，即ji鏈lian條tiao下xia的de物wu料liao對dui刮gua板ban間jian的de物wu料liao摩mo擦ca力li較jiao大da，不bu利li於yu出chu料liao。
