產品概況
回轉式三筒(tong)(tong)烘干機(ji)改進原(yuan)單筒(tong)(tong)烘干機(ji)內部結(jie)構(gou),增(zeng)加(jia)入機(ji)前(qian)濕料的(de)預烘干和延(yan)長濕料在(zai)機(ji)內烘干時間,再加(jia)上密封、保溫以及合理的(de)配(pei)套措施,使(shi)烘干機(ji)生(sheng)產(chan)能力與原(yuan)單筒(tong)(tong)式烘干機(ji)相比,提高48-80%,單位(wei)容(rong)積蒸發強度可達120-180kg/m3,標準煤耗(hao)僅為6-8kg/t。其技術先進、運行參數合理,操作簡單可行,廣泛應用(yong)于(yu)各個行業的(de)礦渣、粘土、煤。
產(chan)品結構
三(san)筒烘(hong)干(gan)機(ji)(ji)是通過對單筒烘(hong)干(gan)機(ji)(ji)的單筒體(ti)(ti)改為套疊(die)在一起的三(san)筒,以(yi)縮短烘(hong)干(gan)機(ji)(ji)體(ti)(ti)的外形尺寸。該(gai)機(ji)(ji)工作時,物料和熱(re)氣流依次進(jin)入(ru)內(nei)至外筒體(ti)(ti),在機(ji)(ji)體(ti)(ti)Z形往復(fu)折(zhe)流后,充分利用熱(re)能烘(hong)干(gan)物料后再(zai)卸(xie)出(chu)。
烘干機筒體(ti)部分(fen)由(you)三(san)個(ge)同(tong)軸水(shui)平放置的內、中、外(wai)筒套疊組成,這就使筒體(ti)的截面(mian)(mian)得(de)到充分(fen)的利(li)用。其筒體(ti)外(wai)形總(zong)長度(du)約(yue)為(wei)與之相當的單筒的30-35%。從(cong)而大幅(fu)度(du)地減(jian)少占地面(mian)(mian)積(ji)和廠(chang)房建筑(zhu)面(mian)(mian)積(ji)。
該(gai)機的支承(cheng)(cheng)裝(zhuang)置,是(shi)在(zai)外筒(tong)上輪(lun)帶與托輪(lun)支承(cheng)(cheng),由電機直接帶動托輪(lun)。通過托輪(lun)與輪(lun)帶摩擦,使筒(tong)體轉動。該(gai)機總體結構緊湊、合理、簡單,為便于磨損件的檢修更換,在(zai)中間設計成(cheng)軸(zhou)向剖分式,用螺栓固定連接。
