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(ji)筒(tong)體(ti)(ti)部分由三個同軸水平放置(zhi)的內(nei)、中(zhong)、外筒(tong)套疊組成,這就使(shi)筒(tong)體(ti)(ti)的截面(mian)得(de)到充分的利用。其筒(tong)體(ti)(ti)外形總長度約為與(yu)之相當的單(dan)筒(tong)的30-35%。從(cong)而(er)大幅度地(di)減(jian)少占地(di)面(mian)積和廠房建筑面(mian)積。
該機的(de)支承(cheng)裝置(zhi),是在外筒(tong)(tong)上輪(lun)帶(dai)與(yu)托(tuo)輪(lun)支承(cheng),由電機直接(jie)帶(dai)動(dong)托(tuo)輪(lun)。通過托(tuo)輪(lun)與(yu)輪(lun)帶(dai)摩擦(ca),使筒(tong)(tong)體轉(zhuan)動(dong)。該機總(zong)體結(jie)構緊湊、合理(li)、簡單,為便于(yu)磨損件的(de)檢修更換(huan),在中(zhong)間(jian)設計(ji)成軸向(xiang)剖(pou)分式,用螺栓(shuan)固(gu)定連(lian)接(jie)。
