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(ji)筒(tong)(tong)體部分由(you)三(san)個(ge)同軸水平放置的(de)(de)內、中、外(wai)筒(tong)(tong)套疊組成,這就使筒(tong)(tong)體的(de)(de)截面(mian)得到充分的(de)(de)利(li)用。其筒(tong)(tong)體外(wai)形總(zong)長度約為與(yu)之相當的(de)(de)單筒(tong)(tong)的(de)(de)30-35%。從(cong)而(er)大幅度地減(jian)少占地面(mian)積和廠(chang)房建筑(zhu)面(mian)積。
該機的(de)支承(cheng)裝(zhuang)置(zhi),是在外(wai)筒(tong)上(shang)輪(lun)帶與托(tuo)輪(lun)支承(cheng),由電機直接(jie)帶動托(tuo)輪(lun)。通過(guo)托(tuo)輪(lun)與輪(lun)帶摩擦(ca),使筒(tong)體(ti)轉動。該機總體(ti)結構(gou)緊(jin)湊、合理、簡(jian)單,為便于磨損件的(de)檢修更換,在中間(jian)設計(ji)成軸(zhou)向剖分式,用(yong)螺栓固定連接(jie)。
