產品結構
大型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)體部分(fen)由三個同軸水平放置的內、中、外筒(tong)套疊組成,這(zhe)就使筒(tong)體的截面(mian)得(de)到充分(fen)的利用。其筒(tong)體外形總長度(du)約(yue)為與之相當的單(dan)筒(tong)的30-35%。從而大幅度(du)地減少占地面(mian)積(ji)和廠房(fang)建筑面(mian)積(ji)。
該機的支承裝(zhuang)置,是在(zai)外筒(tong)(tong)上輪(lun)帶與托輪(lun)支承,由電機直(zhi)接帶動托輪(lun)。通過托輪(lun)與輪(lun)帶摩擦,使筒(tong)(tong)體(ti)轉(zhuan)動。該機總體(ti)結構(gou)緊湊(cou)、合理、簡單,為便于磨損件的檢修更換,在(zai)中間設計成軸向剖(pou)分式(shi),用螺(luo)栓固定連接。
