產品(pin)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。
烘干機筒(tong)(tong)體部分(fen)由三個同軸(zhou)水平放(fang)置(zhi)的(de)內、中、外(wai)筒(tong)(tong)套疊組成,這(zhe)就使筒(tong)(tong)體的(de)截(jie)面(mian)得(de)到充分(fen)的(de)利用。其筒(tong)(tong)體外(wai)形總長度(du)約為與(yu)之相(xiang)當(dang)的(de)單筒(tong)(tong)的(de)30-35%。從而大幅(fu)度(du)地(di)減少占地(di)面(mian)積和廠房建(jian)筑面(mian)積。
該機(ji)的(de)支(zhi)承(cheng)裝置,是在外筒上輪(lun)帶與托輪(lun)支(zhi)承(cheng),由電機(ji)直接帶動托輪(lun)。通(tong)過(guo)托輪(lun)與輪(lun)帶摩擦,使筒體轉動。該機(ji)總體結構(gou)緊(jin)湊、合理、簡單,為便于磨損件(jian)的(de)檢修更(geng)換,在中間設計成軸向剖分(fen)式,用(yong)螺栓固定連接。
