產品(pin)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(tong)體部分由三(san)個(ge)同軸水平放置的(de)(de)內、中(zhong)、外筒(tong)套疊(die)組成,這就(jiu)使筒(tong)體的(de)(de)截面(mian)(mian)(mian)得到充(chong)分的(de)(de)利用。其筒(tong)體外形總(zong)長(chang)度約為與之相當的(de)(de)單筒(tong)的(de)(de)30-35%。從而大幅度地(di)減少(shao)占地(di)面(mian)(mian)(mian)積和廠房建筑面(mian)(mian)(mian)積。
該機的支承(cheng)裝置,是在(zai)外筒(tong)上輪(lun)(lun)帶(dai)與(yu)托輪(lun)(lun)支承(cheng),由電(dian)機直(zhi)接帶(dai)動托輪(lun)(lun)。通(tong)過托輪(lun)(lun)與(yu)輪(lun)(lun)帶(dai)摩擦,使(shi)筒(tong)體(ti)轉動。該機總體(ti)結構緊湊、合(he)理、簡單,為便于(yu)磨損件的檢修更(geng)換,在(zai)中間設(she)計成軸向(xiang)剖分(fen)式,用螺栓固定連(lian)接。
