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、中、外(wai)(wai)筒(tong)套疊組成,這就(jiu)使筒(tong)體(ti)的(de)(de)截(jie)面(mian)得到充分的(de)(de)利(li)用。其筒(tong)體(ti)外(wai)(wai)形總長度約為與之相當的(de)(de)單筒(tong)的(de)(de)30-35%。從而(er)大幅度地減少占地面(mian)積和廠房建筑面(mian)積。
該(gai)機的(de)支承裝(zhuang)置,是在外(wai)筒上輪(lun)帶(dai)與(yu)托(tuo)輪(lun)支承,由電機直接帶(dai)動托(tuo)輪(lun)。通過托(tuo)輪(lun)與(yu)輪(lun)帶(dai)摩擦,使(shi)筒體轉動。該(gai)機總體結構緊湊、合理、簡單,為便(bian)于磨損件的(de)檢修更換(huan),在中間設計成(cheng)軸(zhou)向剖分式,用螺(luo)栓固定連接。
