產品結構
三筒烘干機是通過對單筒烘干機的單筒體改為套疊在一起的三筒,以縮短烘干機體的外形尺寸。該機工作時,物料和熱氣流依次進入內至外筒體,在機體Z形往復折流后,充分利用熱能烘干物料后再卸出。
烘干機(ji)筒(tong)體部分由三個同軸水平放置的(de)(de)內、中、外筒(tong)套疊組成,這就使筒(tong)體的(de)(de)截面得到充分的(de)(de)利用(yong)。其(qi)筒(tong)體外形總長度約(yue)為與之(zhi)相當的(de)(de)單筒(tong)的(de)(de)30-35%。從而(er)大幅度地(di)減(jian)少占地(di)面積和(he)廠房(fang)建筑面積。
該(gai)機(ji)的(de)支承裝置,是在外筒上輪帶(dai)(dai)與托輪支承,由電(dian)機(ji)直(zhi)接帶(dai)(dai)動(dong)托輪。通過托輪與輪帶(dai)(dai)摩擦,使(shi)筒體轉(zhuan)動(dong)。該(gai)機(ji)總體結構緊湊、合理、簡單,為便(bian)于(yu)磨損件(jian)的(de)檢修更換,在中間設(she)計成軸向剖(pou)分式,用螺栓固定連接。
