產品(pin)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。
烘干機筒(tong)(tong)(tong)體部分(fen)由三個同軸水(shui)平放置的(de)內、中、外筒(tong)(tong)(tong)套疊組成,這就使筒(tong)(tong)(tong)體的(de)截(jie)面得到(dao)充分(fen)的(de)利用。其筒(tong)(tong)(tong)體外形總長(chang)度約為與之相當的(de)單筒(tong)(tong)(tong)的(de)30-35%。從而大幅度地減(jian)少(shao)占(zhan)地面積和(he)廠房建筑面積。
該(gai)機的(de)支承裝(zhuang)置,是在外(wai)筒上輪(lun)(lun)帶(dai)與(yu)托(tuo)輪(lun)(lun)支承,由電機直接(jie)帶(dai)動托(tuo)輪(lun)(lun)。通過(guo)托(tuo)輪(lun)(lun)與(yu)輪(lun)(lun)帶(dai)摩擦,使筒體(ti)(ti)轉動。該(gai)機總(zong)體(ti)(ti)結構緊(jin)湊(cou)、合理、簡單,為便(bian)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,用(yong)螺栓固(gu)定(ding)連接(jie)。
工作原理
