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(ji)筒體(ti)部(bu)分由三個(ge)同軸水平放置(zhi)的(de)內、中、外筒套疊組(zu)成,這就使筒體(ti)的(de)截面(mian)得到(dao)充(chong)分的(de)利(li)用。其筒體(ti)外形總長(chang)度(du)約為與之相(xiang)當的(de)單筒的(de)30-35%。從(cong)而(er)大幅度(du)地(di)減(jian)少(shao)占地(di)面(mian)積(ji)和(he)廠房建筑面(mian)積(ji)。
該機(ji)(ji)的(de)支(zhi)承裝置,是在外筒上(shang)輪(lun)(lun)帶與(yu)托輪(lun)(lun)支(zhi)承,由電機(ji)(ji)直接(jie)帶動(dong)托輪(lun)(lun)。通過托輪(lun)(lun)與(yu)輪(lun)(lun)帶摩擦,使筒體(ti)轉動(dong)。該機(ji)(ji)總體(ti)結構緊湊、合理、簡單(dan),為便于磨損件(jian)的(de)檢(jian)修(xiu)更換,在中間設(she)計成軸向剖分(fen)式,用螺栓固(gu)定連接(jie)。
