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。
烘干機筒體(ti)部分由三個同軸水平放(fang)置的(de)(de)內、中、外(wai)(wai)筒套疊(die)組成,這就使筒體(ti)的(de)(de)截面得到充分的(de)(de)利用。其筒體(ti)外(wai)(wai)形總長度(du)約(yue)為與之相當的(de)(de)單筒的(de)(de)30-35%。從而大幅(fu)度(du)地減少占(zhan)地面積(ji)(ji)和廠房建(jian)筑面積(ji)(ji)。
該機(ji)的支(zhi)承裝(zhuang)置,是在(zai)外(wai)筒上輪(lun)(lun)帶與托(tuo)輪(lun)(lun)支(zhi)承,由電(dian)機(ji)直(zhi)接帶動托(tuo)輪(lun)(lun)。通(tong)過托(tuo)輪(lun)(lun)與輪(lun)(lun)帶摩擦(ca),使(shi)筒體轉動。該機(ji)總(zong)體結構緊(jin)湊、合理、簡單,為便于(yu)磨損件(jian)的檢修(xiu)更(geng)換,在(zai)中(zhong)間(jian)設計成軸向剖分式,用螺栓固定連接。
