產(chan)品結構
三筒(tong)(tong)烘干機(ji)(ji)是通過對單(dan)筒(tong)(tong)烘干機(ji)(ji)的(de)單(dan)筒(tong)(tong)體(ti)改(gai)為套疊在一起的(de)三筒(tong)(tong),以縮短烘干機(ji)(ji)體(ti)的(de)外形尺寸。該機(ji)(ji)工作時,物(wu)料和熱氣流依次進入內至外筒(tong)(tong)體(ti),在機(ji)(ji)體(ti)Z形往復折(zhe)流后(hou),充分利用熱能烘干物(wu)料后(hou)再卸出。
烘干機筒(tong)體部分(fen)由三個同軸水平放置的(de)(de)內(nei)、中、外筒(tong)套疊組成,這就使筒(tong)體的(de)(de)截面得到充(chong)分(fen)的(de)(de)利用。其筒(tong)體外形(xing)總長度約為與之相(xiang)當的(de)(de)單筒(tong)的(de)(de)30-35%。從而大幅度地減少(shao)占地面積和廠(chang)房建筑面積。
該機(ji)的支承(cheng)裝置,是在(zai)外筒上輪(lun)(lun)帶(dai)與托(tuo)輪(lun)(lun)支承(cheng),由(you)電機(ji)直接(jie)帶(dai)動托(tuo)輪(lun)(lun)。通過托(tuo)輪(lun)(lun)與輪(lun)(lun)帶(dai)摩擦,使筒體(ti)轉動。該機(ji)總體(ti)結(jie)構緊湊、合理(li)、簡單,為便于磨損件的檢(jian)修更換,在(zai)中(zhong)間(jian)設計成軸(zhou)向剖分式(shi),用螺栓固(gu)定(ding)連接(jie)。
