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。
烘干機筒(tong)(tong)體部分由三個同軸水平放(fang)置的內、中、外筒(tong)(tong)套疊組成,這就使(shi)筒(tong)(tong)體的截面得到(dao)充分的利用。其筒(tong)(tong)體外形總長(chang)度約為與之相當的單筒(tong)(tong)的30-35%。從而(er)大(da)幅度地減少(shao)占地面積(ji)和(he)廠房(fang)建筑(zhu)面積(ji)。
該機(ji)的(de)支承(cheng)裝置(zhi),是在(zai)外筒上(shang)輪(lun)帶(dai)與托(tuo)輪(lun)支承(cheng),由電機(ji)直接帶(dai)動(dong)托(tuo)輪(lun)。通過托(tuo)輪(lun)與輪(lun)帶(dai)摩擦,使筒體轉動(dong)。該機(ji)總(zong)體結(jie)構緊湊、合理、簡單,為便于磨損件的(de)檢修更換,在(zai)中(zhong)間設計(ji)成軸向(xiang)剖分式,用螺栓(shuan)固定連(lian)接。
