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(gan)機筒(tong)(tong)體部分由三(san)個(ge)同(tong)軸水平放置(zhi)的內、中、外筒(tong)(tong)套疊組(zu)成,這就(jiu)使(shi)筒(tong)(tong)體的截面得到(dao)充分的利用。其筒(tong)(tong)體外形總長度(du)約為與(yu)之相當的單筒(tong)(tong)的30-35%。從而大(da)幅度(du)地減少占地面積和廠房建筑面積。
該(gai)機的(de)支(zhi)承裝(zhuang)置,是在外筒上(shang)輪(lun)帶(dai)與(yu)托(tuo)輪(lun)支(zhi)承,由電機直接帶(dai)動(dong)托(tuo)輪(lun)。通(tong)過(guo)托(tuo)輪(lun)與(yu)輪(lun)帶(dai)摩擦(ca),使筒體轉動(dong)。該(gai)機總體結構緊湊、合理、簡單,為便(bian)于磨損件(jian)的(de)檢(jian)修更換,在中間(jian)設(she)計成軸向(xiang)剖分式,用螺栓固定連接。
