產品結構
大型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(ji)筒體(ti)部分由三個同軸(zhou)水平放置的內、中、外筒套疊(die)組(zu)成,這就(jiu)使筒體(ti)的截(jie)面得(de)到充分的利用。其筒體(ti)外形(xing)總長度約(yue)為與之相當的單(dan)筒的30-35%。從(cong)而大幅度地減(jian)少占地面積和廠房建筑面積。
該(gai)機(ji)(ji)的支承裝置(zhi),是在(zai)外筒(tong)上輪(lun)帶與(yu)托輪(lun)支承,由(you)電機(ji)(ji)直接帶動(dong)托輪(lun)。通過托輪(lun)與(yu)輪(lun)帶摩擦,使筒(tong)體轉動(dong)。該(gai)機(ji)(ji)總(zong)體結構緊(jin)湊、合理、簡單(dan),為便于(yu)磨損件的檢修更換,在(zai)中間設計(ji)成軸向剖分(fen)式,用螺栓固(gu)定連接。
