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(hong)干機筒(tong)(tong)體(ti)部分(fen)由三個(ge)同軸水平放置的內、中、外筒(tong)(tong)套疊組(zu)成,這(zhe)就(jiu)使筒(tong)(tong)體(ti)的截(jie)面得到充分(fen)的利用。其(qi)筒(tong)(tong)體(ti)外形總(zong)長度約為與之相當的單(dan)筒(tong)(tong)的30-35%。從而(er)大幅度地減少占地面積(ji)和廠(chang)房建筑面積(ji)。
該機的支承裝置,是在(zai)外筒上輪(lun)(lun)帶與托輪(lun)(lun)支承,由電機直(zhi)接帶動托輪(lun)(lun)。通過托輪(lun)(lun)與輪(lun)(lun)帶摩擦,使筒體轉動。該機總體結構緊湊、合理(li)、簡單,為便于磨損件的檢修更換,在(zai)中間設計成(cheng)軸向剖分式,用螺栓(shuan)固(gu)定(ding)連接。
工作原理
