產品結構
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。
烘干(gan)機(ji)筒(tong)(tong)(tong)體(ti)部分由三個同軸水平放(fang)置的內、中(zhong)、外筒(tong)(tong)(tong)套疊組(zu)成,這就(jiu)使筒(tong)(tong)(tong)體(ti)的截面得到充分的利用(yong)。其筒(tong)(tong)(tong)體(ti)外形(xing)總長(chang)度約為與(yu)之相當(dang)的單筒(tong)(tong)(tong)的30-35%。從而大(da)幅度地減少占地面積(ji)和(he)廠(chang)房(fang)建筑面積(ji)。
該機(ji)(ji)的支承裝置,是在(zai)外筒上輪(lun)帶(dai)與(yu)托輪(lun)支承,由電機(ji)(ji)直接帶(dai)動(dong)托輪(lun)。通過托輪(lun)與(yu)輪(lun)帶(dai)摩(mo)擦,使筒體(ti)(ti)轉動(dong)。該機(ji)(ji)總(zong)體(ti)(ti)結(jie)構緊湊、合理、簡單,為便(bian)于磨(mo)損件(jian)的檢(jian)修更換,在(zai)中間設計(ji)成軸向剖分式,用(yong)螺栓固定連接。
