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。
烘干機筒體部分由(you)三個同軸水平放置的內(nei)、中、外筒套疊組成,這就使筒體的截面(mian)(mian)得到(dao)充分的利用。其筒體外形總長度約(yue)為與之(zhi)相當的單(dan)筒的30-35%。從而大幅度地減(jian)少占地面(mian)(mian)積和(he)廠房(fang)建筑面(mian)(mian)積。
該機的支(zhi)承裝置,是在外筒(tong)上輪帶(dai)與(yu)托輪支(zhi)承,由電機直接(jie)帶(dai)動托輪。通過托輪與(yu)輪帶(dai)摩擦,使筒(tong)體(ti)轉動。該機總體(ti)結構緊湊、合(he)理、簡單,為便于磨損件的檢修更(geng)換,在中間設(she)計(ji)成軸(zhou)向剖(pou)分(fen)式,用螺(luo)栓固定連接(jie)。
