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)(tong)(tong)體部分由三個同軸水平放置的(de)(de)內、中(zhong)、外筒(tong)(tong)(tong)套疊組成,這就使筒(tong)(tong)(tong)體的(de)(de)截面得到充分的(de)(de)利用。其筒(tong)(tong)(tong)體外形總長(chang)度約(yue)為與(yu)之相當(dang)的(de)(de)單筒(tong)(tong)(tong)的(de)(de)30-35%。從而大幅(fu)度地(di)減少占地(di)面積(ji)和廠房建筑(zhu)面積(ji)。
該機(ji)的(de)支承裝置,是在(zai)外筒上(shang)輪(lun)帶與(yu)(yu)托輪(lun)支承,由電機(ji)直接帶動(dong)托輪(lun)。通過(guo)托輪(lun)與(yu)(yu)輪(lun)帶摩擦,使(shi)筒體轉動(dong)。該機(ji)總體結構緊湊、合理、簡單,為便于磨(mo)損件的(de)檢修更換(huan),在(zai)中間設計成軸向剖分式,用螺栓固定連(lian)接。
