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。

烘干機筒體部分由三個(ge)同(tong)軸水平(ping)放置的內(nei)、中、外筒套疊組成，這就使筒體的截面(mian)得(de)到(dao)充分的利(li)用(yong)。其筒體外形總(zong)長度(du)(du)約為(wei)與之(zhi)相當的單筒的30-35%。從而大(da)幅度(du)(du)地減少占地面(mian)積(ji)和(he)廠房建筑面(mian)積(ji)。

該機的(de)支(zhi)承裝置(zhi)，是在(zai)外筒上輪(lun)帶(dai)與托輪(lun)支(zhi)承，由電機直接帶(dai)動托輪(lun)。通過(guo)托輪(lun)與輪(lun)帶(dai)摩擦，使筒體轉動。該機總體結構緊湊、合理、簡單(dan)，為(wei)便于磨損件(jian)的(de)檢修更換(huan)，在(zai)中間設計(ji)成軸向剖分式，用螺栓固定(ding)連接。
