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)干機筒體部分(fen)由三個同軸(zhou)水平放置的內、中、外筒套疊組成,這就使筒體的截面得(de)到(dao)充(chong)分(fen)的利用。其筒體外形(xing)總長(chang)度約為與之相當的單(dan)筒的30-35%。從而大幅度地減少占地面積和(he)廠(chang)房建(jian)筑面積。
該(gai)機(ji)的(de)支承裝(zhuang)置,是(shi)在外筒上(shang)輪(lun)帶(dai)(dai)(dai)與托(tuo)輪(lun)支承,由(you)電(dian)機(ji)直接帶(dai)(dai)(dai)動托(tuo)輪(lun)。通(tong)過托(tuo)輪(lun)與輪(lun)帶(dai)(dai)(dai)摩擦,使(shi)筒體(ti)轉動。該(gai)機(ji)總(zong)體(ti)結構緊湊、合理、簡(jian)單,為便于磨損(sun)件的(de)檢修更(geng)換(huan),在中間設計成軸向(xiang)剖分式(shi),用(yong)螺栓固定連接。
