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)體(ti)部分由三(san)個同軸水(shui)平放(fang)置的(de)(de)內(nei)、中、外筒(tong)套疊組(zu)成,這就(jiu)使(shi)筒(tong)體(ti)的(de)(de)截面得到充分的(de)(de)利用。其筒(tong)體(ti)外形總(zong)長度約(yue)為與之相(xiang)當的(de)(de)單筒(tong)的(de)(de)30-35%。從而大幅度地減(jian)少占地面積和廠房建(jian)筑面積。
該(gai)(gai)機(ji)的(de)支承裝置,是在外筒上輪(lun)帶(dai)與(yu)托輪(lun)支承,由(you)電機(ji)直接帶(dai)動(dong)托輪(lun)。通過托輪(lun)與(yu)輪(lun)帶(dai)摩擦(ca),使筒體(ti)轉動(dong)。該(gai)(gai)機(ji)總體(ti)結構緊湊、合理、簡單,為(wei)便于磨損件(jian)的(de)檢修更(geng)換,在中間(jian)設計成軸向剖分式,用螺(luo)栓固定連接。
