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。
烘干機筒體部(bu)分由三個同軸水平放置(zhi)的內、中、外(wai)筒套疊組(zu)成,這就使筒體的截(jie)面得到充分的利用。其筒體外(wai)形總長度約為與之相當的單筒的30-35%。從而大幅(fu)度地減少占地面積和廠(chang)房建(jian)筑面積。
該機(ji)(ji)的支承(cheng)裝置,是在外筒上輪(lun)帶與托輪(lun)支承(cheng),由(you)電機(ji)(ji)直接帶動托輪(lun)。通過托輪(lun)與輪(lun)帶摩(mo)擦,使筒體轉動。該機(ji)(ji)總體結構(gou)緊(jin)湊(cou)、合理(li)、簡單,為(wei)便(bian)于(yu)磨損件的檢(jian)修更換,在中間(jian)設(she)計成軸向剖(pou)分式,用螺栓固(gu)定連接。
