產品結構

大型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(die)組(zu)成，這(zhe)就使筒(tong)(tong)體(ti)的(de)截面得到充分(fen)的(de)利用。其筒(tong)(tong)體(ti)外(wai)形總(zong)長(chang)度約為與之相當的(de)單(dan)筒(tong)(tong)的(de)30-35%。從而大幅(fu)度地減少占地面積和(he)廠房建筑(zhu)面積。

該機的支(zhi)承裝置，是在(zai)外(wai)筒上輪帶(dai)與(yu)托輪支(zhi)承，由(you)電機直(zhi)接(jie)帶(dai)動托輪。通(tong)過托輪與(yu)輪帶(dai)摩擦(ca)，使筒體轉動。該機總體結構(gou)緊湊、合(he)理、簡單(dan)，為便于(yu)磨損件的檢修更換，在(zai)中間(jian)設計成軸向剖分(fen)式，用螺栓(shuan)固定連接(jie)。
