產品結構
三筒式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(hong)干機筒體(ti)部分由(you)三個同軸水平放置(zhi)的(de)(de)內、中、外(wai)筒套疊(die)組成,這就(jiu)使(shi)筒體(ti)的(de)(de)截面得(de)到充分的(de)(de)利用(yong)。其筒體(ti)外(wai)形(xing)總長度約為與之相(xiang)當的(de)(de)單筒的(de)(de)30-35%。從(cong)而大幅(fu)度地(di)減少占(zhan)地(di)面積(ji)和廠房(fang)建筑(zhu)面積(ji)。
該(gai)機(ji)的支承(cheng)裝(zhuang)置,是(shi)在(zai)外筒(tong)上輪(lun)帶(dai)與(yu)托(tuo)輪(lun)支承(cheng),由電(dian)機(ji)直接帶(dai)動(dong)托(tuo)輪(lun)。通(tong)過托(tuo)輪(lun)與(yu)輪(lun)帶(dai)摩(mo)擦,使(shi)筒(tong)體(ti)轉動(dong)。該(gai)機(ji)總體(ti)結(jie)構緊湊、合(he)理、簡(jian)單,為便于磨(mo)損件的檢修更換,在(zai)中(zhong)間設計成軸向剖分式,用螺栓固定連接。
