產品結構
三筒式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(tong)體(ti)部分由三(san)個同(tong)軸水平放置(zhi)的(de)(de)內、中、外筒(tong)套疊組成,這就使筒(tong)體(ti)的(de)(de)截面得到充分的(de)(de)利用。其筒(tong)體(ti)外形總長度約(yue)為與之相當(dang)的(de)(de)單筒(tong)的(de)(de)30-35%。從而大幅度地減少占地面積和(he)廠房(fang)建(jian)筑面積。
該(gai)機(ji)的支承(cheng)裝置,是在外筒上輪(lun)帶(dai)與(yu)托(tuo)輪(lun)支承(cheng),由電機(ji)直接帶(dai)動托(tuo)輪(lun)。通(tong)過托(tuo)輪(lun)與(yu)輪(lun)帶(dai)摩(mo)擦(ca),使筒體轉動。該(gai)機(ji)總體結構(gou)緊湊、合理、簡單,為便于磨損(sun)件的檢修更換,在中間設計(ji)成軸向剖分式,用螺栓(shuan)固定連接。
