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(ti)部分(fen)由三個同軸水平放置的(de)(de)內、中、外(wai)筒套疊組成(cheng),這就(jiu)使筒體(ti)的(de)(de)截面得到充(chong)分(fen)的(de)(de)利用。其筒體(ti)外(wai)形總長度約為與之相當的(de)(de)單筒的(de)(de)30-35%。從而大幅度地減少占地面積(ji)(ji)和(he)廠房建筑面積(ji)(ji)。
該機的支承(cheng)裝置,是在(zai)外筒上輪(lun)(lun)(lun)帶與(yu)托輪(lun)(lun)(lun)支承(cheng),由電(dian)機直(zhi)接帶動(dong)托輪(lun)(lun)(lun)。通過(guo)托輪(lun)(lun)(lun)與(yu)輪(lun)(lun)(lun)帶摩擦,使筒體轉動(dong)。該機總(zong)體結構緊湊、合理(li)、簡單,為便于磨(mo)損件的檢(jian)修(xiu)更(geng)換,在(zai)中間設計成軸向剖分式(shi),用(yong)螺栓(shuan)固定(ding)連接。
