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)機筒體部分(fen)由三個(ge)同軸水平(ping)放置的內、中(zhong)、外筒套疊組成(cheng),這就使筒體的截(jie)面(mian)得到(dao)充分(fen)的利用。其筒體外形(xing)總長度(du)約為與之相當的單筒的30-35%。從(cong)而(er)大幅度(du)地減少占(zhan)地面(mian)積和廠房建筑面(mian)積。
該(gai)(gai)機(ji)(ji)的支(zhi)承裝置,是在(zai)外筒上(shang)輪(lun)(lun)帶與(yu)托輪(lun)(lun)支(zhi)承,由電機(ji)(ji)直接帶動托輪(lun)(lun)。通過(guo)托輪(lun)(lun)與(yu)輪(lun)(lun)帶摩擦,使筒體轉動。該(gai)(gai)機(ji)(ji)總體結構緊湊、合理、簡單,為便于(yu)磨(mo)損件的檢修更換,在(zai)中間設(she)計成軸向剖分式(shi),用螺栓固定連接。
