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(fen)由三個同軸水平放置(zhi)的(de)內、中、外筒(tong)套疊組成,這(zhe)就使筒(tong)體的(de)截(jie)面(mian)得到充分(fen)的(de)利用。其筒(tong)體外形總長度約為與之相當(dang)的(de)單筒(tong)的(de)30-35%。從而大幅度地減少占(zhan)地面(mian)積(ji)和(he)廠房(fang)建筑面(mian)積(ji)。
該(gai)機的支承裝置,是在外筒上(shang)輪帶與托(tuo)輪支承,由電機直接帶動托(tuo)輪。通(tong)過托(tuo)輪與輪帶摩擦(ca),使筒體(ti)轉(zhuan)動。該(gai)機總體(ti)結構緊(jin)湊、合理(li)、簡單(dan),為便于磨損(sun)件(jian)的檢修更換,在中間設計成軸向剖分式,用螺栓固定(ding)連接。
