斗(dou)(dou)(dou)式(shi)提(ti)(ti)升机(ji)(ji)是利(li)用均匀固(gu)接(jie)(jie)于无端牵(qian)引构件上(shang)的一系(xi)列(lie)料斗(dou)(dou)(dou)，竖向提(ti)(ti)升物料的连续(xu)输(shu)送(song)机(ji)(ji)械，斗(dou)(dou)(dou)式(shi)提(ti)(ti)升机(ji)(ji)利(li)用一系(xi)列(lie)固(gu)接(jie)(jie)在(zai)牵(qian)引链(lian)或(huo)胶(jiao)带(dai)上(shang)的料斗(dou)(dou)(dou)在(zai)竖直(zhi)或(huo)接(jie)(jie)近竖直(zhi)方向内(nei)向上(shang)运送(song)散(san)料。分(fen)为环链(lian)、板链(lian)和皮带(dai)三种。斗(dou)(dou)(dou)式(shi)提(ti)(ti)升机(ji)(ji)主要(yao)性能及参(can)数符合JB3926--85《垂(chui)直(zhi)斗(dou)(dou)(dou)式(shi)提(ti)(ti)升机(ji)(ji)》(该(gai)标(biao)准等效参(can)照了国(guo)际标(biao)准和国(guo)外先(xian)进标(biao)准)。

斗式(shi)提升机工作原理:

料(liao)(liao)斗(dou)(dou)把物料(liao)(liao)从下(xia)面(mian)(mian)的(de)储(chu)藏中舀起(qi)，随(sui)着输送带或链(lian)(lian)提(ti)(ti)升(sheng)(sheng)(sheng)(sheng)到顶(ding)部，绕(rao)过(guo)顶(ding)轮后向下(xia)翻转(zhuan)， 斗(dou)(dou)式提(ti)(ti)升(sheng)(sheng)(sheng)(sheng)机(ji)将(jiang)物料(liao)(liao)倾入接受(shou)槽(cao)内。带传动(dong)(dong)的(de)斗(dou)(dou)式提(ti)(ti)升(sheng)(sheng)(sheng)(sheng)机(ji)的(de)传动(dong)(dong)带一般(ban)采用橡胶带，装(zhuang)(zhuang)(zhuang)在下(xia)或上(shang)面(mian)(mian)的(de)传动(dong)(dong)滚筒(tong)和上(shang)下(xia)面(mian)(mian)的(de)改向滚筒(tong)上(shang)。链(lian)(lian)传动(dong)(dong)的(de)斗(dou)(dou)式提(ti)(ti)升(sheng)(sheng)(sheng)(sheng)机(ji)一般(ban)装(zhuang)(zhuang)(zhuang)有两条平(ping)行的(de)传动(dong)(dong)链(lian)(lian)，上(shang)或下(xia)面(mian)(mian)有一对(dui)传动(dong)(dong)链(lian)(lian)轮，下(xia)或上(shang)面(mian)(mian)是一对(dui)改向链(lian)(lian)轮。斗(dou)(dou)式提(ti)(ti)升(sheng)(sheng)(sheng)(sheng)机(ji)一般(ban)都装(zhuang)(zhuang)(zhuang)有机(ji)壳(qiao)，以防(fang)止斗(dou)(dou)式提(ti)(ti)升(sheng)(sheng)(sheng)(sheng)机(ji)中粉尘(chen)飞(fei)扬(yang)。斗(dou)(dou)式提(ti)(ti)升(sheng)(sheng)(sheng)(sheng)机(ji)：适(shi)用于(yu)低处(chu)往高处(chu)提(ti)(ti)升(sheng)(sheng)(sheng)(sheng)，供应物料(liao)(liao)通过(guo)振动(dong)(dong)台投入料(liao)(liao)斗(dou)(dou)后机(ji)器自(zi)动(dong)(dong)连续运(yun)转(zhuan)向上(shang)运(yun)送。
