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(gan)機筒(tong)體部分由三個同(tong)軸水平(ping)放置的(de)內、中、外筒(tong)套(tao)疊組成(cheng),這就使筒(tong)體的(de)截(jie)面(mian)得到(dao)充分的(de)利用。其筒(tong)體外形(xing)總長(chang)度約為與(yu)之相當(dang)的(de)單筒(tong)的(de)30-35%。從而大幅度地減少(shao)占地面(mian)積(ji)和廠房建筑面(mian)積(ji)。
該機(ji)的支承(cheng)裝置,是在外筒上輪(lun)帶(dai)與托輪(lun)支承(cheng),由電機(ji)直接帶(dai)動托輪(lun)。通過托輪(lun)與輪(lun)帶(dai)摩(mo)擦,使筒體(ti)(ti)轉動。該機(ji)總體(ti)(ti)結構緊湊、合理、簡(jian)單,為(wei)便于(yu)磨(mo)損件的檢修更(geng)換,在中間設計成軸向(xiang)剖(pou)分式,用(yong)螺(luo)栓固定連接。
