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(gan)機筒體(ti)部分(fen)(fen)由三(san)個同軸水平放置(zhi)的內、中、外筒套疊組(zu)成,這就使筒體(ti)的截(jie)面(mian)(mian)得到充(chong)分(fen)(fen)的利用。其(qi)筒體(ti)外形總長度約為與之相當的單(dan)筒的30-35%。從(cong)而(er)大幅度地減(jian)少占地面(mian)(mian)積(ji)和(he)廠房建筑面(mian)(mian)積(ji)。
該(gai)(gai)機(ji)的支承(cheng)(cheng)裝置(zhi),是(shi)在外筒(tong)上(shang)輪(lun)(lun)帶與托輪(lun)(lun)支承(cheng)(cheng),由電(dian)機(ji)直接(jie)帶動托輪(lun)(lun)。通(tong)過托輪(lun)(lun)與輪(lun)(lun)帶摩擦,使筒(tong)體轉動。該(gai)(gai)機(ji)總體結構緊(jin)湊(cou)、合理、簡單,為(wei)便于磨(mo)損件(jian)的檢修更換,在中間設計成(cheng)軸向剖(pou)分式(shi),用螺栓固(gu)定連接(jie)。
