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(tong)(tong)體(ti)部分由三個同軸(zhou)水平放(fang)置(zhi)的(de)(de)內、中、外筒(tong)(tong)套疊(die)組成(cheng)，這就使筒(tong)(tong)體(ti)的(de)(de)截面得(de)到充分的(de)(de)利用。其(qi)筒(tong)(tong)體(ti)外形總(zong)長度約為與之相當(dang)的(de)(de)單筒(tong)(tong)的(de)(de)30-35%。從(cong)而大幅度地減少占地面積和廠房(fang)建筑面積。

該機(ji)的支承(cheng)裝置，是(shi)在(zai)外筒(tong)(tong)上輪(lun)(lun)帶與(yu)托輪(lun)(lun)支承(cheng)，由(you)電機(ji)直接帶動(dong)托輪(lun)(lun)。通過托輪(lun)(lun)與(yu)輪(lun)(lun)帶摩擦，使筒(tong)(tong)體轉動(dong)。該機(ji)總體結構(gou)緊湊、合理、簡單(dan)，為(wei)便(bian)于磨損件的檢修(xiu)更換，在(zai)中間設計成軸向(xiang)剖分式，用螺栓(shuan)固(gu)定連接。
