產(chan)品概況
回轉(zhuan)式(shi)三筒(tong)(tong)(tong)烘(hong)干機改進(jin)原單(dan)(dan)(dan)筒(tong)(tong)(tong)烘(hong)干機內部(bu)結構，增(zeng)加入機前(qian)濕料的(de)(de)預烘(hong)干和(he)延(yan)長濕料在機內烘(hong)干時間，再加上(shang)密封、保溫(wen)以及合理的(de)(de)配套措(cuo)施，使烘(hong)干機生產能力與原單(dan)(dan)(dan)筒(tong)(tong)(tong)式(shi)烘(hong)干機相比，提高(gao)48-80%，單(dan)(dan)(dan)位容積蒸發強度可達(da)120-180kg/m3，標準煤耗僅為6-8kg/t。其技術先(xian)進(jin)、運行參數合理，操(cao)作簡單(dan)(dan)(dan)可行，廣泛(fan)應用于各個行業的(de)(de)礦(kuang)渣、粘(zhan)土、煤。
產品結構
三筒烘(hong)干(gan)機(ji)是通過對(dui)單筒烘(hong)干(gan)機(ji)的(de)單筒體(ti)改(gai)為套疊在一(yi)起的(de)三筒，以縮短烘(hong)干(gan)機(ji)體(ti)的(de)外形尺寸。該機(ji)工作時(shi)，物料和熱氣流依次進入內至外筒體(ti)，在機(ji)體(ti)Z形往復(fu)折流后，充分利用熱能烘(hong)干(gan)物料后再卸出。
烘干機筒(tong)(tong)體部分由(you)三個同軸水平放置(zhi)的內(nei)、中(zhong)、外筒(tong)(tong)套疊組成，這就使筒(tong)(tong)體的截面得到充分的利用。其筒(tong)(tong)體外形總長度(du)約為與之相當的單筒(tong)(tong)的30-35%。從而大(da)幅度(du)地(di)減(jian)少占地(di)面積和(he)廠房建筑(zhu)面積。
該機的支承裝(zhuang)置(zhi)，是在外筒上輪帶與托輪支承，由電機直接(jie)(jie)帶動托輪。通(tong)過(guo)托輪與輪帶摩擦，使(shi)筒體轉動。該機總體結(jie)構緊湊、合(he)理、簡單，為(wei)便于磨損件的檢修更換(huan)，在中間設計成軸向(xiang)剖分式，用螺栓(shuan)固定連(lian)接(jie)(jie)。
工作(zuo)原理
