產品結構
大型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。
烘干機筒(tong)(tong)體(ti)部分由三(san)個同(tong)軸(zhou)水平放置(zhi)的(de)內(nei)、中、外筒(tong)(tong)套(tao)疊組(zu)成(cheng),這就使筒(tong)(tong)體(ti)的(de)截面得(de)到(dao)充分的(de)利用。其筒(tong)(tong)體(ti)外形總長度(du)約為與之(zhi)相當(dang)的(de)單筒(tong)(tong)的(de)30-35%。從(cong)而(er)大幅度(du)地減少占地面積(ji)(ji)和(he)廠(chang)房建筑面積(ji)(ji)。
該(gai)機的支(zhi)承(cheng)裝(zhuang)置,是在外筒上輪(lun)帶與(yu)托輪(lun)支(zhi)承(cheng),由電(dian)機直接(jie)(jie)帶動(dong)托輪(lun)。通(tong)過托輪(lun)與(yu)輪(lun)帶摩擦,使筒體轉動(dong)。該(gai)機總體結構緊湊(cou)、合理、簡(jian)單(dan),為便于(yu)磨(mo)損件(jian)的檢修更換(huan),在中間設計成軸向剖分式,用螺栓(shuan)固定連(lian)接(jie)(jie)。
