產品結構(gou)
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(gan)機(ji)筒(tong)體部分由三個同軸(zhou)水(shui)平放置(zhi)的(de)內、中(zhong)、外(wai)筒(tong)套(tao)疊組成,這(zhe)就使筒(tong)體的(de)截面(mian)(mian)得(de)到充分的(de)利用。其筒(tong)體外(wai)形總(zong)長度(du)約為與之(zhi)相當的(de)單筒(tong)的(de)30-35%。從(cong)而大幅度(du)地減少占地面(mian)(mian)積和廠(chang)房(fang)建(jian)筑面(mian)(mian)積。
該(gai)機的支(zhi)承裝置,是(shi)在(zai)外(wai)筒上輪(lun)帶與托輪(lun)支(zhi)承,由電機直接帶動托輪(lun)。通過托輪(lun)與輪(lun)帶摩擦,使筒體轉動。該(gai)機總(zong)體結構(gou)緊湊、合理、簡單,為(wei)便于磨損件的檢(jian)修更換,在(zai)中間設計成軸向(xiang)剖分式,用螺栓固定(ding)連接。
