產品結構(gou)
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。
烘干機筒體(ti)部分(fen)由三個同(tong)軸(zhou)水平(ping)放置的內、中、外(wai)筒套(tao)疊組成,這就使筒體(ti)的截面得到充分(fen)的利用。其筒體(ti)外(wai)形總(zong)長度(du)約(yue)為與之(zhi)相當的單筒的30-35%。從(cong)而(er)大(da)幅度(du)地減少占地面積和廠房建筑面積。
該(gai)機(ji)的(de)支承(cheng)裝置,是(shi)在外筒(tong)上(shang)輪(lun)帶(dai)與(yu)托(tuo)(tuo)輪(lun)支承(cheng),由電機(ji)直接帶(dai)動(dong)托(tuo)(tuo)輪(lun)。通(tong)過托(tuo)(tuo)輪(lun)與(yu)輪(lun)帶(dai)摩擦,使筒(tong)體轉動(dong)。該(gai)機(ji)總體結構(gou)緊湊、合(he)理、簡單,為便于磨損件(jian)的(de)檢修更換,在中間設計成軸(zhou)向剖分式,用螺栓固定連接。
