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)體部(bu)分由(you)三(san)個同軸水平放(fang)置的(de)內、中、外(wai)筒(tong)套(tao)疊組(zu)成,這就使筒(tong)體的(de)截面(mian)得(de)到充分的(de)利(li)用。其筒(tong)體外(wai)形總長(chang)度(du)(du)約為(wei)與之相當的(de)單筒(tong)的(de)30-35%。從(cong)而大(da)幅度(du)(du)地(di)減少(shao)占地(di)面(mian)積和廠房建筑面(mian)積。
該機的支承裝置,是在外筒上輪(lun)(lun)(lun)帶(dai)與托(tuo)輪(lun)(lun)(lun)支承,由電機直接帶(dai)動(dong)托(tuo)輪(lun)(lun)(lun)。通過托(tuo)輪(lun)(lun)(lun)與輪(lun)(lun)(lun)帶(dai)摩(mo)擦(ca),使筒體轉動(dong)。該機總(zong)體結構緊湊、合理、簡(jian)單,為(wei)便于磨損件(jian)的檢修更換,在中間設計成軸向剖分式,用螺(luo)栓固定連接。
