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(tong)(tong)體(ti)部分(fen)由三個同軸水平(ping)放置(zhi)的(de)內、中、外(wai)筒(tong)(tong)套疊組成,這就使(shi)筒(tong)(tong)體(ti)的(de)截面得到充分(fen)的(de)利用。其(qi)筒(tong)(tong)體(ti)外(wai)形(xing)總(zong)長度約為(wei)與之相當的(de)單(dan)筒(tong)(tong)的(de)30-35%。從而大幅度地減少占地面積和廠(chang)房(fang)建筑(zhu)面積。
該(gai)機的(de)支承裝置,是在外(wai)筒上輪帶(dai)(dai)與托(tuo)輪支承,由(you)電機直接(jie)帶(dai)(dai)動(dong)托(tuo)輪。通過(guo)托(tuo)輪與輪帶(dai)(dai)摩擦,使(shi)筒體轉(zhuan)動(dong)。該(gai)機總體結構緊湊(cou)、合(he)理、簡單,為便于(yu)磨損件的(de)檢修更(geng)換,在中間設(she)計成軸向(xiang)剖(pou)分式,用(yong)螺栓固(gu)定(ding)連(lian)接(jie)。
