產品結構
大型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)體部分由三個(ge)同軸水平放(fang)置的(de)(de)內、中、外筒(tong)(tong)套疊(die)組成(cheng),這就使(shi)筒(tong)(tong)體的(de)(de)截(jie)面(mian)(mian)得到充分的(de)(de)利用(yong)。其筒(tong)(tong)體外形總(zong)長度(du)約為與之相當的(de)(de)單筒(tong)(tong)的(de)(de)30-35%。從而大幅(fu)度(du)地(di)減少占地(di)面(mian)(mian)積和廠房建(jian)筑面(mian)(mian)積。
該機(ji)(ji)的支(zhi)承(cheng)裝置,是在外筒上輪帶(dai)(dai)與托(tuo)輪支(zhi)承(cheng),由電(dian)機(ji)(ji)直接(jie)帶(dai)(dai)動托(tuo)輪。通過托(tuo)輪與輪帶(dai)(dai)摩擦,使筒體轉動。該機(ji)(ji)總體結構緊(jin)湊、合(he)理、簡單(dan),為便于磨(mo)損件的檢修(xiu)更(geng)換,在中(zhong)間設計(ji)成(cheng)軸向(xiang)剖分式,用(yong)螺栓固定連(lian)接(jie)。
