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(gan)機筒(tong)體(ti)部分由(you)三個同軸水(shui)平放置的(de)內、中(zhong)、外(wai)筒(tong)套疊組成,這就使(shi)筒(tong)體(ti)的(de)截面(mian)得到充分的(de)利用。其筒(tong)體(ti)外(wai)形總長度約為與之(zhi)相當的(de)單筒(tong)的(de)30-35%。從而大(da)幅度地減(jian)少占地面(mian)積和廠(chang)房建(jian)筑面(mian)積。
該(gai)機的支(zhi)承裝置(zhi),是在(zai)外筒上輪(lun)(lun)帶與托輪(lun)(lun)支(zhi)承,由電機直接帶動托輪(lun)(lun)。通過托輪(lun)(lun)與輪(lun)(lun)帶摩(mo)擦,使筒體轉動。該(gai)機總(zong)體結構(gou)緊湊、合理、簡(jian)單(dan),為便于磨損件的檢修更(geng)換(huan),在(zai)中間設計成(cheng)軸向剖(pou)分式,用螺栓固定連接。
