產(chan)品結構(gou)
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)干機筒體(ti)部分由(you)三個(ge)同軸水平放置的(de)內(nei)、中、外筒套疊(die)組成,這就(jiu)使(shi)筒體(ti)的(de)截面得(de)到充(chong)分的(de)利用。其筒體(ti)外形總長度(du)約為與之(zhi)相當的(de)單筒的(de)30-35%。從而大幅度(du)地(di)減(jian)少占地(di)面積和廠房建筑(zhu)面積。
該機(ji)的(de)支(zhi)承裝置(zhi),是在外筒上(shang)輪(lun)帶(dai)與托(tuo)(tuo)輪(lun)支(zhi)承,由電機(ji)直接帶(dai)動(dong)托(tuo)(tuo)輪(lun)。通過托(tuo)(tuo)輪(lun)與輪(lun)帶(dai)摩擦(ca),使(shi)筒體轉(zhuan)動(dong)。該機(ji)總體結構緊湊、合理、簡單,為便于磨損件(jian)的(de)檢修更換,在中間設(she)計成軸向(xiang)剖分式(shi),用(yong)螺栓固定連接。
