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。
烘干機筒(tong)體部分(fen)由三個同軸水平(ping)放置的(de)(de)(de)內、中、外筒(tong)套(tao)疊組成,這(zhe)就使筒(tong)體的(de)(de)(de)截面得到充分(fen)的(de)(de)(de)利用。其筒(tong)體外形總長度(du)約為與之相當的(de)(de)(de)單筒(tong)的(de)(de)(de)30-35%。從而大幅度(du)地減少占地面積和廠房(fang)建筑(zhu)面積。
該機的(de)支(zhi)承(cheng)裝(zhuang)置,是在(zai)(zai)外筒上輪(lun)(lun)帶與托(tuo)輪(lun)(lun)支(zhi)承(cheng),由電(dian)機直接帶動托(tuo)輪(lun)(lun)。通過托(tuo)輪(lun)(lun)與輪(lun)(lun)帶摩擦,使筒體轉動。該機總(zong)體結構緊湊、合理、簡單,為便于磨損件的(de)檢修更換,在(zai)(zai)中間設計成軸向剖(pou)分式,用螺栓固定連接。
