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。
烘干機筒(tong)(tong)體部分由三(san)個同軸水(shui)平放置的(de)(de)內、中、外(wai)筒(tong)(tong)套疊組成(cheng),這就(jiu)使筒(tong)(tong)體的(de)(de)截面得到充分的(de)(de)利(li)用。其筒(tong)(tong)體外(wai)形總長度(du)約為與之相當的(de)(de)單(dan)筒(tong)(tong)的(de)(de)30-35%。從而(er)大(da)幅度(du)地(di)減(jian)少占地(di)面積(ji)和廠房建(jian)筑面積(ji)。
該(gai)機(ji)的支承裝(zhuang)置,是在外(wai)筒上輪(lun)帶(dai)與(yu)托輪(lun)支承,由電機(ji)直接帶(dai)動托輪(lun)。通過托輪(lun)與(yu)輪(lun)帶(dai)摩擦,使筒體轉動。該(gai)機(ji)總(zong)體結(jie)構緊湊、合(he)理、簡單(dan),為(wei)便于磨損件的檢修更換,在中間設計成軸(zhou)向(xiang)剖(pou)分(fen)式,用螺栓固(gu)定連(lian)接。
