產(chan)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(ji)筒(tong)(tong)體(ti)部分由三個同軸水平放置的(de)內、中、外(wai)筒(tong)(tong)套疊(die)組成,這就(jiu)使筒(tong)(tong)體(ti)的(de)截(jie)面(mian)得到充分的(de)利用。其筒(tong)(tong)體(ti)外(wai)形總長度約為與之相(xiang)當的(de)單筒(tong)(tong)的(de)30-35%。從而大幅度地減少占地面(mian)積和廠房建筑面(mian)積。
該機的(de)支(zhi)承(cheng)裝置,是在外筒上(shang)輪帶(dai)(dai)與(yu)托輪支(zhi)承(cheng),由電(dian)機直接帶(dai)(dai)動托輪。通(tong)過托輪與(yu)輪帶(dai)(dai)摩擦,使筒體(ti)(ti)轉動。該機總體(ti)(ti)結構緊湊、合理、簡單,為便(bian)于磨(mo)損件的(de)檢(jian)修(xiu)更換,在中間設計成軸向剖分式,用螺栓固定連(lian)接。
