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(gan)機筒體部分(fen)由三個同軸水平(ping)放置的(de)(de)內、中、外筒套疊(die)組成,這就使筒體的(de)(de)截面得到充(chong)分(fen)的(de)(de)利(li)用。其(qi)筒體外形總長度約為(wei)與之相當的(de)(de)單筒的(de)(de)30-35%。從而大幅度地減少占(zhan)地面積和廠房建筑(zhu)面積。
該機的支(zhi)承(cheng)裝置,是在外筒上(shang)輪(lun)帶(dai)(dai)與(yu)托(tuo)輪(lun)支(zhi)承(cheng),由電機直接帶(dai)(dai)動(dong)托(tuo)輪(lun)。通過托(tuo)輪(lun)與(yu)輪(lun)帶(dai)(dai)摩擦(ca),使筒體轉動(dong)。該機總體結構緊(jin)湊、合理、簡單(dan),為便于(yu)磨損件的檢修更換,在中(zhong)間(jian)設計成軸向剖分式,用(yong)螺栓固定連接。
