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)體部分由三(san)個(ge)同軸水平(ping)放置的(de)(de)內、中(zhong)、外筒(tong)套(tao)疊組(zu)成,這就使筒(tong)體的(de)(de)截面(mian)得到(dao)充分的(de)(de)利用。其筒(tong)體外形總(zong)長度約為與之相當的(de)(de)單筒(tong)的(de)(de)30-35%。從而大(da)幅度地減少占地面(mian)積(ji)和廠房(fang)建(jian)筑(zhu)面(mian)積(ji)。
該機的支承裝置(zhi),是(shi)在外筒(tong)上輪(lun)帶與托輪(lun)支承,由電機直接帶動托輪(lun)。通過托輪(lun)與輪(lun)帶摩擦(ca),使筒(tong)體(ti)轉(zhuan)動。該機總體(ti)結構緊(jin)湊、合(he)理、簡單,為(wei)便于磨(mo)損件的檢修更換,在中間設計(ji)成軸(zhou)向剖分式(shi),用螺栓固定連接。
