產品結構
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)機筒(tong)(tong)體(ti)部(bu)分由三個同軸水平放置的(de)內、中、外(wai)筒(tong)(tong)套疊組成,這就使筒(tong)(tong)體(ti)的(de)截面(mian)得到(dao)充(chong)分的(de)利用(yong)。其筒(tong)(tong)體(ti)外(wai)形總長度約為與(yu)之相當的(de)單筒(tong)(tong)的(de)30-35%。從而大幅(fu)度地(di)減少占地(di)面(mian)積和廠(chang)房(fang)建(jian)筑面(mian)積。
該機的支(zhi)承(cheng)裝置,是在外筒(tong)(tong)上輪(lun)(lun)(lun)帶(dai)與(yu)托輪(lun)(lun)(lun)支(zhi)承(cheng),由電機直接帶(dai)動托輪(lun)(lun)(lun)。通過托輪(lun)(lun)(lun)與(yu)輪(lun)(lun)(lun)帶(dai)摩擦,使(shi)筒(tong)(tong)體轉動。該機總體結構緊(jin)湊(cou)、合(he)理、簡(jian)單,為便于磨(mo)損件的檢修(xiu)更(geng)換(huan),在中(zhong)間設計成軸(zhou)向剖分式,用螺栓(shuan)固定連接。
