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(gan)機筒(tong)體(ti)部分由三(san)個同(tong)軸水(shui)平放置的(de)內、中(zhong)、外(wai)筒(tong)套疊組成(cheng),這就(jiu)使筒(tong)體(ti)的(de)截面(mian)得到充分的(de)利用。其筒(tong)體(ti)外(wai)形總長度約為與之(zhi)相當(dang)的(de)單筒(tong)的(de)30-35%。從(cong)而大幅度地減少占(zhan)地面(mian)積(ji)和廠房建(jian)筑(zhu)面(mian)積(ji)。
該(gai)機(ji)的支承裝置,是(shi)在(zai)外(wai)筒上輪(lun)(lun)(lun)帶(dai)與(yu)(yu)托(tuo)輪(lun)(lun)(lun)支承,由電機(ji)直(zhi)接帶(dai)動(dong)(dong)托(tuo)輪(lun)(lun)(lun)。通過托(tuo)輪(lun)(lun)(lun)與(yu)(yu)輪(lun)(lun)(lun)帶(dai)摩擦(ca),使筒體(ti)轉(zhuan)動(dong)(dong)。該(gai)機(ji)總體(ti)結(jie)構緊湊、合(he)理(li)、簡單(dan),為便(bian)于磨(mo)損件的檢修更換,在(zai)中(zhong)間(jian)設計成軸向剖分式,用螺栓固定連(lian)接。
