產品結構
三筒式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(you)三個同軸水(shui)平放(fang)置的(de)(de)內(nei)、中(zhong)、外筒(tong)(tong)套(tao)疊組成,這就使(shi)筒(tong)(tong)體(ti)的(de)(de)截(jie)面(mian)得到充(chong)分的(de)(de)利用。其(qi)筒(tong)(tong)體(ti)外形總長度約為(wei)與之相當的(de)(de)單筒(tong)(tong)的(de)(de)30-35%。從而大幅度地減少占地面(mian)積和廠(chang)房建筑面(mian)積。
該機的支承裝(zhuang)置,是在(zai)外筒上輪帶(dai)與托輪支承,由電機直接(jie)(jie)帶(dai)動托輪。通過(guo)托輪與輪帶(dai)摩擦,使(shi)筒體(ti)轉動。該機總(zong)體(ti)結(jie)構緊(jin)湊、合理(li)、簡(jian)單,為便于磨損件的檢(jian)修更(geng)換,在(zai)中間設計成軸(zhou)向剖分式(shi),用螺栓固定連接(jie)(jie)。
