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(hong)干機筒(tong)體部(bu)分由(you)三個同軸水平(ping)放置的內(nei)、中(zhong)、外筒(tong)套疊組成,這就使筒(tong)體的截面得到(dao)充(chong)分的利用(yong)。其(qi)筒(tong)體外形總長度約為與之相當的單筒(tong)的30-35%。從而(er)大幅(fu)度地(di)減少占地(di)面積和廠房建筑(zhu)面積。
該機的支承裝置,是在外筒上輪(lun)(lun)帶(dai)與托(tuo)輪(lun)(lun)支承,由電機直接帶(dai)動托(tuo)輪(lun)(lun)。通過托(tuo)輪(lun)(lun)與輪(lun)(lun)帶(dai)摩擦,使筒體轉動。該機總體結構緊湊(cou)、合理、簡單,為便(bian)于(yu)磨損(sun)件的檢修更(geng)換,在中間設(she)計成軸(zhou)向剖分式,用螺栓固定連接。
