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(ji)筒(tong)體(ti)部分(fen)由三個同軸(zhou)水平放置的(de)內、中、外筒(tong)套疊組成,這(zhe)就使筒(tong)體(ti)的(de)截面(mian)得到充(chong)分(fen)的(de)利用。其筒(tong)體(ti)外形總(zong)長度約為與之相當的(de)單(dan)筒(tong)的(de)30-35%。從而大幅度地減少(shao)占地面(mian)積和(he)廠房建筑面(mian)積。
該機的支承(cheng)裝置,是在外筒(tong)上輪(lun)(lun)帶(dai)(dai)(dai)與(yu)托(tuo)輪(lun)(lun)支承(cheng),由電機直接(jie)帶(dai)(dai)(dai)動(dong)托(tuo)輪(lun)(lun)。通過托(tuo)輪(lun)(lun)與(yu)輪(lun)(lun)帶(dai)(dai)(dai)摩擦(ca),使(shi)筒(tong)體轉動(dong)。該機總體結構緊(jin)湊(cou)、合理、簡單,為便于(yu)磨損件的檢修更換(huan),在中間設(she)計(ji)成軸(zhou)向剖分(fen)式,用(yong)螺栓固(gu)定連接(jie)。
