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)體部分(fen)由三個同軸水平放(fang)置的內、中、外(wai)筒(tong)(tong)套疊組成(cheng),這就使筒(tong)(tong)體的截面(mian)得到充(chong)分(fen)的利用。其(qi)筒(tong)(tong)體外(wai)形總長度約為與之相當的單筒(tong)(tong)的30-35%。從而大幅度地(di)減少(shao)占(zhan)地(di)面(mian)積(ji)和廠房建筑面(mian)積(ji)。
該機的支承(cheng)裝置,是在(zai)外筒上輪帶與(yu)托(tuo)輪支承(cheng),由電機直接(jie)帶動托(tuo)輪。通過托(tuo)輪與(yu)輪帶摩(mo)擦,使(shi)筒體轉動。該機總體結構緊湊、合理(li)、簡(jian)單,為便(bian)于(yu)磨(mo)損件的檢修更換,在(zai)中(zhong)間設計成(cheng)軸向(xiang)剖分式,用螺栓固(gu)定連接(jie)。
