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(ti)(ti)部分由三個(ge)同軸(zhou)水平(ping)放置的(de)內、中、外(wai)筒(tong)(tong)套疊組成,這就使筒(tong)(tong)體(ti)(ti)的(de)截面(mian)得到充分的(de)利用。其筒(tong)(tong)體(ti)(ti)外(wai)形總(zong)長度約(yue)為與之相當(dang)的(de)單筒(tong)(tong)的(de)30-35%。從而大幅(fu)度地減少占地面(mian)積和廠房(fang)建筑面(mian)積。
該機(ji)的支承(cheng)裝(zhuang)置,是在(zai)外筒上輪(lun)(lun)帶(dai)與托輪(lun)(lun)支承(cheng),由電機(ji)直接帶(dai)動(dong)(dong)托輪(lun)(lun)。通過托輪(lun)(lun)與輪(lun)(lun)帶(dai)摩擦,使筒體轉動(dong)(dong)。該機(ji)總體結構緊(jin)湊、合理(li)、簡(jian)單,為便于磨(mo)損件的檢修更換(huan),在(zai)中(zhong)間(jian)設(she)計成軸向(xiang)剖分(fen)式(shi),用螺栓固定(ding)連接。
