產品結構
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(tong)體(ti)(ti)部分由三個(ge)同軸水平放置(zhi)的內、中、外(wai)筒(tong)套疊組成,這就使筒(tong)體(ti)(ti)的截面(mian)得到充分的利用。其筒(tong)體(ti)(ti)外(wai)形總(zong)長度約(yue)為與之(zhi)相當的單筒(tong)的30-35%。從而大幅度地(di)減少占地(di)面(mian)積和(he)廠(chang)房建筑面(mian)積。
該機(ji)(ji)的(de)支承裝置(zhi),是(shi)在(zai)外筒上輪帶與托輪支承,由(you)電機(ji)(ji)直接(jie)帶動托輪。通(tong)過托輪與輪帶摩擦,使筒體(ti)轉(zhuan)動。該機(ji)(ji)總體(ti)結構緊湊(cou)、合理、簡單(dan),為便于磨損件的(de)檢修更(geng)換,在(zai)中間設計成軸向剖分式,用螺栓(shuan)固定連接(jie)。
