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(hong)干機筒(tong)體(ti)部分由三個(ge)同(tong)軸水平放置的(de)(de)內、中(zhong)、外(wai)筒(tong)套疊組(zu)成,這就使筒(tong)體(ti)的(de)(de)截(jie)面得到(dao)充(chong)分的(de)(de)利用。其筒(tong)體(ti)外(wai)形總長度約(yue)為與之相當的(de)(de)單筒(tong)的(de)(de)30-35%。從(cong)而(er)大幅度地減少(shao)占地面積(ji)和(he)廠(chang)房建筑面積(ji)。
該機的支(zhi)承(cheng)裝置(zhi),是在(zai)外筒(tong)上輪(lun)(lun)帶與托輪(lun)(lun)支(zhi)承(cheng),由(you)電機直接帶動托輪(lun)(lun)。通過托輪(lun)(lun)與輪(lun)(lun)帶摩擦,使筒(tong)體轉動。該機總體結構緊湊、合(he)理、簡(jian)單,為便于磨損件的檢修更換(huan),在(zai)中間設(she)計成軸向剖分(fen)式(shi),用螺(luo)栓固(gu)定連接。
