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。
烘干機筒(tong)(tong)體部(bu)分由三個同軸水平(ping)放置的(de)內、中(zhong)、外筒(tong)(tong)套疊組成,這就使筒(tong)(tong)體的(de)截面得(de)到充分的(de)利用(yong)。其筒(tong)(tong)體外形總長度(du)約為與之(zhi)相(xiang)當的(de)單(dan)筒(tong)(tong)的(de)30-35%。從而大幅度(du)地(di)(di)減少(shao)占地(di)(di)面積和廠(chang)房(fang)建(jian)筑面積。
該機的(de)支承裝置(zhi),是在外筒(tong)上輪(lun)帶與(yu)托輪(lun)支承,由電機直接帶動(dong)托輪(lun)。通過(guo)托輪(lun)與(yu)輪(lun)帶摩擦(ca),使筒(tong)體(ti)轉動(dong)。該機總體(ti)結構(gou)緊湊、合理(li)、簡單,為(wei)便于(yu)磨損件的(de)檢修更換,在中(zhong)間設計成軸(zhou)向剖分式,用螺栓固(gu)定連接。
