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。
烘干機筒體部分由三個同軸水平(ping)放置的(de)(de)內、中、外筒套疊組成,這就使筒體的(de)(de)截面得到充(chong)分的(de)(de)利用。其筒體外形總長(chang)度(du)約為與之相當的(de)(de)單(dan)筒的(de)(de)30-35%。從而大幅(fu)度(du)地(di)減少占地(di)面積和(he)廠房建(jian)筑(zhu)面積。
該機的支承裝置,是(shi)在(zai)外筒(tong)上輪帶與托(tuo)(tuo)輪支承,由電(dian)機直接帶動(dong)(dong)托(tuo)(tuo)輪。通過(guo)托(tuo)(tuo)輪與輪帶摩擦,使(shi)筒(tong)體轉動(dong)(dong)。該機總(zong)體結構緊湊、合理(li)、簡單,為(wei)便(bian)于磨(mo)損件的檢修更(geng)換,在(zai)中間設(she)計成軸向(xiang)剖分式,用螺(luo)栓(shuan)固定連接。
