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(ti)部分(fen)由三個同軸(zhou)水平放置的(de)(de)內、中、外筒(tong)套疊組成(cheng),這就使筒(tong)體(ti)的(de)(de)截面得到充分(fen)的(de)(de)利用。其筒(tong)體(ti)外形總長度(du)約為與(yu)之相當的(de)(de)單筒(tong)的(de)(de)30-35%。從(cong)而大幅度(du)地(di)減少占地(di)面積(ji)和廠(chang)房建(jian)筑面積(ji)。
該機(ji)的支承(cheng)裝置,是(shi)在外筒上輪帶(dai)與(yu)托輪支承(cheng),由電機(ji)直接帶(dai)動托輪。通過(guo)托輪與(yu)輪帶(dai)摩擦,使筒體轉(zhuan)動。該機(ji)總體結構(gou)緊湊、合理、簡(jian)單,為便(bian)于磨損件的檢(jian)修更(geng)換,在中間設計成軸向剖(pou)分(fen)式,用(yong)螺(luo)栓固定(ding)連接。
