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(ji)筒(tong)體部分由三個(ge)同軸水平放置的(de)內、中(zhong)、外(wai)筒(tong)套疊組成(cheng),這就使筒(tong)體的(de)截面(mian)得到(dao)充(chong)分的(de)利(li)用。其筒(tong)體外(wai)形總長度約為與之(zhi)相當的(de)單筒(tong)的(de)30-35%。從而大(da)幅度地減少占地面(mian)積和廠房建筑面(mian)積。
該(gai)機(ji)(ji)的支(zhi)承(cheng)裝置(zhi),是在外(wai)筒(tong)(tong)上輪(lun)(lun)帶(dai)與托輪(lun)(lun)支(zhi)承(cheng),由(you)電(dian)機(ji)(ji)直接帶(dai)動托輪(lun)(lun)。通過托輪(lun)(lun)與輪(lun)(lun)帶(dai)摩擦,使筒(tong)(tong)體轉動。該(gai)機(ji)(ji)總體結構緊湊(cou)、合(he)理、簡單(dan),為便于(yu)磨損件的檢修更換(huan),在中間設計成軸(zhou)向剖分式,用螺栓固定連接。
工作原理
