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。
烘干機筒體(ti)部(bu)分由(you)三個(ge)同軸(zhou)水(shui)平放置(zhi)的(de)內(nei)、中、外筒套疊(die)組成,這就使筒體(ti)的(de)截(jie)面(mian)得到充(chong)分的(de)利用(yong)。其筒體(ti)外形總長度(du)約為與之相當的(de)單筒的(de)30-35%。從而大幅度(du)地(di)減少占(zhan)地(di)面(mian)積和(he)廠房建筑面(mian)積。
該機(ji)的支承裝置,是在(zai)外筒上輪(lun)(lun)帶(dai)(dai)與(yu)托輪(lun)(lun)支承,由電機(ji)直接(jie)帶(dai)(dai)動(dong)托輪(lun)(lun)。通過托輪(lun)(lun)與(yu)輪(lun)(lun)帶(dai)(dai)摩擦,使筒體轉動(dong)。該機(ji)總體結構(gou)緊(jin)湊、合理(li)、簡單,為(wei)便于磨損(sun)件的檢(jian)修更換(huan),在(zai)中間(jian)設計成(cheng)軸向剖分式,用(yong)螺栓固(gu)定連接(jie)。
