產品概況
回轉式三筒烘(hong)(hong)干機改進(jin)原單(dan)筒烘(hong)(hong)干機內部(bu)結構，增(zeng)加入機前濕(shi)料(liao)的預烘(hong)(hong)干和延長濕(shi)料(liao)在機內烘(hong)(hong)干時(shi)間，再(zai)加上(shang)密(mi)封、保溫以(yi)及合理的配(pei)套(tao)措施，使烘(hong)(hong)干機生產能力與原單(dan)筒式烘(hong)(hong)干機相(xiang)比，提高(gao)48-80%，單(dan)位(wei)容積(ji)蒸(zheng)發強度可(ke)達120-180kg/m3，標準煤(mei)耗僅為6-8kg/t。其技術先進(jin)、運行(xing)(xing)參數(shu)合理，操作簡單(dan)可(ke)行(xing)(xing)，廣泛應用(yong)于各個行(xing)(xing)業(ye)的礦渣、粘(zhan)土(tu)、煤(mei)。
產品結構
三筒(tong)(tong)烘(hong)干(gan)機是通(tong)過對單(dan)筒(tong)(tong)烘(hong)干(gan)機的單(dan)筒(tong)(tong)體改(gai)為套疊在一起的三筒(tong)(tong)，以縮短烘(hong)干(gan)機體的外形(xing)尺寸。該(gai)機工作時(shi)，物料和(he)熱(re)氣流依次進入內(nei)至外筒(tong)(tong)體，在機體Z形(xing)往復(fu)折流后，充分利用(yong)熱(re)能烘(hong)干(gan)物料后再(zai)卸(xie)出。
烘干機(ji)筒(tong)體(ti)部(bu)分(fen)由三個同軸(zhou)水平放置的(de)(de)內、中(zhong)、外(wai)筒(tong)套(tao)疊組(zu)成(cheng)，這就使筒(tong)體(ti)的(de)(de)截面(mian)得到充分(fen)的(de)(de)利用。其筒(tong)體(ti)外(wai)形(xing)總長(chang)度約為與之相當(dang)的(de)(de)單(dan)筒(tong)的(de)(de)30-35%。從而大幅度地(di)減少(shao)占地(di)面(mian)積和廠房建筑面(mian)積。
該機的支(zhi)承裝置(zhi)，是(shi)在外筒上輪(lun)帶與托輪(lun)支(zhi)承，由電機直接(jie)帶動托輪(lun)。通(tong)過托輪(lun)與輪(lun)帶摩擦，使筒體轉動。該機總體結構緊湊、合理、簡單(dan)，為便于(yu)磨損件(jian)的檢修更換，在中間設計成軸(zhou)向剖分(fen)式，用螺栓(shuan)固(gu)定連接(jie)。
