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)體部分(fen)由三個同軸(zhou)水平放置的(de)內、中、外筒(tong)套(tao)疊組(zu)成,這就(jiu)使(shi)筒(tong)體的(de)截面得(de)到充分(fen)的(de)利(li)用。其筒(tong)體外形總長度(du)約為與之相當(dang)的(de)單筒(tong)的(de)30-35%。從(cong)而大幅度(du)地減少占地面積(ji)和廠房建(jian)筑面積(ji)。
該(gai)機的支承裝置,是在外(wai)筒(tong)上輪(lun)(lun)帶與托輪(lun)(lun)支承,由電機直接帶動(dong)托輪(lun)(lun)。通過(guo)托輪(lun)(lun)與輪(lun)(lun)帶摩擦(ca),使筒(tong)體轉動(dong)。該(gai)機總體結構緊湊、合(he)理、簡單,為便于磨損(sun)件的檢修更換,在中間(jian)設計(ji)成軸向剖分式,用(yong)螺栓固定連接。
