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。
烘干機筒(tong)(tong)體(ti)部分由三個同軸水(shui)平放置的內(nei)、中(zhong)、外(wai)筒(tong)(tong)套疊組成(cheng),這就使筒(tong)(tong)體(ti)的截面得到(dao)充分的利用(yong)。其筒(tong)(tong)體(ti)外(wai)形總長度約為與之相當的單(dan)筒(tong)(tong)的30-35%。從而大幅度地減少占地面積和廠房(fang)建筑面積。
該(gai)機的支(zhi)承裝置,是在(zai)外筒上輪(lun)(lun)帶與托輪(lun)(lun)支(zhi)承,由電機直接(jie)帶動托輪(lun)(lun)。通(tong)過托輪(lun)(lun)與輪(lun)(lun)帶摩擦(ca),使(shi)筒體(ti)轉動。該(gai)機總體(ti)結構緊湊、合理、簡單(dan),為便于磨損件的檢(jian)修更換,在(zai)中間設計成軸向剖(pou)分式,用螺栓固(gu)定(ding)連接(jie)。
