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(ji)筒(tong)體部分由三個同(tong)軸水平放置的(de)(de)內、中(zhong)、外筒(tong)套疊組成,這就使筒(tong)體的(de)(de)截面得到充分的(de)(de)利用。其筒(tong)體外形總長(chang)度(du)約為與(yu)之相當的(de)(de)單筒(tong)的(de)(de)30-35%。從而大幅度(du)地(di)減少(shao)占地(di)面積和廠房建筑面積。
該機的支(zhi)承裝置,是在外筒上(shang)輪(lun)(lun)(lun)(lun)帶(dai)與托(tuo)輪(lun)(lun)(lun)(lun)支(zhi)承,由電機直接帶(dai)動托(tuo)輪(lun)(lun)(lun)(lun)。通過托(tuo)輪(lun)(lun)(lun)(lun)與輪(lun)(lun)(lun)(lun)帶(dai)摩(mo)擦,使筒體轉動。該機總體結構緊湊(cou)、合理、簡單,為便于磨損件(jian)的檢修更換,在中(zhong)間設(she)計(ji)成軸向剖分式,用螺栓(shuan)固定連(lian)接。
