產品概況
回轉式三筒烘干機改進原單筒烘干機內部結構,增加入機前濕料的預烘干和延長濕料在機內烘干時間,再加上密封、保溫以及合理的配套措施,使烘干機生產能力與原單筒式烘干機相比,提高48-80%,單位容積蒸發強度可達120-180kg/m3,標準煤耗僅為6-8kg/t。其技術先進、運行參數合理,操作簡單可行,廣泛應用于各個行業的礦渣、粘土、煤。
產品(pin)結構
三(san)(san)筒式(shi)烘(hong)干(gan)機是通過(guo)對單筒烘(hong)干(gan)機的(de)單筒體改為套疊在(zai)一(yi)起的(de)三(san)(san)筒,以(yi)縮短烘(hong)干(gan)機體的(de)外(wai)形尺寸。該機工作時(shi),物料和熱(re)氣流(liu)(liu)依次進入(ru)內至(zhi)外(wai)筒體,在(zai)機體Z形往(wang)復(fu)折(zhe)流(liu)(liu)后,充分利用熱(re)能烘(hong)干(gan)物料后再卸(xie)出。
烘干(gan)機(ji)筒(tong)(tong)體(ti)部分由三個同(tong)軸水平(ping)放置的內、中(zhong)、外筒(tong)(tong)套(tao)疊組成,這(zhe)就(jiu)使筒(tong)(tong)體(ti)的截面得(de)到充分的利用。其筒(tong)(tong)體(ti)外形總(zong)長度約為(wei)與之相當的單筒(tong)(tong)的30-35%。從而大幅度地減(jian)少占(zhan)地面積和(he)廠房建筑面積。
該機(ji)(ji)的支承(cheng)裝置,是(shi)在外筒上輪帶(dai)與托(tuo)(tuo)輪支承(cheng),由電機(ji)(ji)直(zhi)接帶(dai)動托(tuo)(tuo)輪。通(tong)過托(tuo)(tuo)輪與輪帶(dai)摩擦(ca),使筒體轉(zhuan)動。該機(ji)(ji)總體結構(gou)緊湊、合理、簡單,為便(bian)于磨損件的檢修更換(huan),在中間設(she)計成(cheng)軸向剖(pou)分(fen)式,用螺栓固定連接。
