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(hong)干機(ji)筒(tong)體(ti)部分(fen)由三個同(tong)軸水平放置(zhi)的(de)內、中、外筒(tong)套疊組成(cheng),這就使筒(tong)體(ti)的(de)截面(mian)(mian)得到充分(fen)的(de)利用。其筒(tong)體(ti)外形總(zong)長度約為與之相當的(de)單筒(tong)的(de)30-35%。從而大幅度地(di)減少占地(di)面(mian)(mian)積和廠(chang)房建(jian)筑面(mian)(mian)積。
該機(ji)(ji)的(de)支承裝置,是(shi)在(zai)外筒上輪(lun)(lun)帶(dai)與(yu)托輪(lun)(lun)支承,由電機(ji)(ji)直接(jie)帶(dai)動(dong)托輪(lun)(lun)。通過托輪(lun)(lun)與(yu)輪(lun)(lun)帶(dai)摩擦,使筒體轉(zhuan)動(dong)。該機(ji)(ji)總體結構緊(jin)湊、合(he)理、簡(jian)單,為便于磨損件的(de)檢修更(geng)換,在(zai)中間(jian)設計成軸向(xiang)剖分式(shi),用螺栓固定(ding)連接(jie)。
