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)體部分由三個(ge)同軸水平(ping)放置(zhi)的(de)內(nei)、中、外筒(tong)(tong)套(tao)疊組成，這就使筒(tong)(tong)體的(de)截面得到充分的(de)利用(yong)。其筒(tong)(tong)體外形總長度約為與之(zhi)相當的(de)單筒(tong)(tong)的(de)30-35%。從而大幅度地(di)減少占(zhan)地(di)面積和廠(chang)房建(jian)筑(zhu)面積。

該(gai)機(ji)的支(zhi)(zhi)承裝置，是(shi)在(zai)外筒上輪帶與(yu)托(tuo)輪支(zhi)(zhi)承，由(you)電(dian)機(ji)直接帶動托(tuo)輪。通過托(tuo)輪與(yu)輪帶摩擦(ca)，使筒體(ti)轉動。該(gai)機(ji)總體(ti)結構緊湊、合理、簡單，為便于磨損件的檢(jian)修更換(huan)，在(zai)中間設(she)計成軸(zhou)向剖(pou)分式(shi)，用(yong)螺栓固定連接。
