產(chan)品結(jie)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(hong)干(gan)機(ji)筒(tong)體(ti)(ti)部(bu)分由三個(ge)同(tong)軸水平放置(zhi)的(de)(de)內、中、外筒(tong)套疊組成,這就使筒(tong)體(ti)(ti)的(de)(de)截面得到(dao)充分的(de)(de)利(li)用(yong)。其(qi)筒(tong)體(ti)(ti)外形總長度約為與之相當的(de)(de)單筒(tong)的(de)(de)30-35%。從而大(da)幅(fu)度地(di)(di)減少占地(di)(di)面積和(he)廠房建筑面積。
該機(ji)的支(zhi)(zhi)承(cheng)裝置,是在外筒(tong)上輪(lun)帶與托(tuo)輪(lun)支(zhi)(zhi)承(cheng),由電機(ji)直接帶動托(tuo)輪(lun)。通過托(tuo)輪(lun)與輪(lun)帶摩擦,使筒(tong)體轉(zhuan)動。該機(ji)總體結構緊湊(cou)、合理、簡(jian)單,為便于磨(mo)損(sun)件的檢(jian)修更換,在中(zhong)間設計成軸向剖分(fen)式,用螺栓(shuan)固定連接。
