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)(ti)部分(fen)由三(san)個同軸(zhou)水平放置的內、中、外(wai)(wai)筒(tong)(tong)套(tao)疊組成,這(zhe)就使筒(tong)(tong)體(ti)(ti)的截面(mian)得到充分(fen)的利(li)用(yong)。其筒(tong)(tong)體(ti)(ti)外(wai)(wai)形總長度約(yue)為與之相當的單筒(tong)(tong)的30-35%。從(cong)而大幅度地減(jian)少占地面(mian)積(ji)(ji)和廠房建筑面(mian)積(ji)(ji)。
該(gai)機的支(zhi)承裝置(zhi),是(shi)在外筒(tong)上輪(lun)帶與托(tuo)(tuo)輪(lun)支(zhi)承,由電機直接(jie)帶動托(tuo)(tuo)輪(lun)。通過(guo)托(tuo)(tuo)輪(lun)與輪(lun)帶摩擦,使筒(tong)體(ti)轉(zhuan)動。該(gai)機總體(ti)結構緊湊、合理、簡單,為便于磨損(sun)件的檢(jian)修更(geng)換,在中(zhong)間設計成軸向剖分式,用螺栓固(gu)定連接(jie)。
工作(zuo)原理
