產(chan)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(hong)干(gan)機筒(tong)(tong)(tong)(tong)體部(bu)分由三個同軸水平放置的(de)內、中、外筒(tong)(tong)(tong)(tong)套(tao)疊組(zu)成(cheng)，這就(jiu)使筒(tong)(tong)(tong)(tong)體的(de)截面得到充分的(de)利用(yong)。其筒(tong)(tong)(tong)(tong)體外形總(zong)長度約(yue)為與之(zhi)相當(dang)的(de)單(dan)筒(tong)(tong)(tong)(tong)的(de)30-35%。從而(er)大(da)幅(fu)度地(di)減少占地(di)面積和廠房建(jian)筑(zhu)面積。

該機的支承裝置，是在外筒(tong)上輪(lun)(lun)(lun)帶(dai)與(yu)(yu)托輪(lun)(lun)(lun)支承，由電(dian)機直接帶(dai)動(dong)(dong)托輪(lun)(lun)(lun)。通過(guo)托輪(lun)(lun)(lun)與(yu)(yu)輪(lun)(lun)(lun)帶(dai)摩擦(ca)，使(shi)筒(tong)體轉動(dong)(dong)。該機總(zong)體結(jie)構緊湊、合理、簡單，為便于磨損(sun)件的檢修更換(huan)，在中間設計成軸向剖分(fen)式，用螺(luo)栓固定連接。
