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(ji)筒(tong)體部(bu)分由(you)三個同軸水平放置的內、中、外(wai)筒(tong)套(tao)疊組成,這就(jiu)使(shi)筒(tong)體的截面得到充分的利用。其(qi)筒(tong)體外(wai)形總長度(du)(du)約為與之相當(dang)的單筒(tong)的30-35%。從而(er)大幅度(du)(du)地減(jian)少占地面積(ji)和廠房建筑面積(ji)。
該機的(de)支承裝置(zhi),是在外筒上輪(lun)(lun)帶(dai)與(yu)托(tuo)輪(lun)(lun)支承,由(you)電(dian)機直接(jie)帶(dai)動(dong)托(tuo)輪(lun)(lun)。通過托(tuo)輪(lun)(lun)與(yu)輪(lun)(lun)帶(dai)摩擦(ca),使筒體轉動(dong)。該機總(zong)體結構緊湊、合(he)理(li)、簡單(dan),為便于磨損件的(de)檢修更(geng)換,在中間(jian)設計成軸向剖分式,用螺栓固定連(lian)接(jie)。
