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(tong)軸水平放置的(de)內(nei)、中(zhong)、外(wai)筒套疊組成,這就使筒體的(de)截面得到充分的(de)利用(yong)。其筒體外(wai)形總長度約為與(yu)之相當的(de)單筒的(de)30-35%。從而大(da)幅(fu)度地減少占地面積(ji)和廠房建筑面積(ji)。
該機(ji)的支承裝置(zhi),是在(zai)外筒上輪(lun)(lun)帶(dai)與(yu)托輪(lun)(lun)支承,由電(dian)機(ji)直接帶(dai)動(dong)(dong)托輪(lun)(lun)。通過托輪(lun)(lun)與(yu)輪(lun)(lun)帶(dai)摩擦,使筒體(ti)轉動(dong)(dong)。該機(ji)總(zong)體(ti)結(jie)構緊(jin)湊、合(he)理、簡單,為便于磨損(sun)件的檢修更(geng)換,在(zai)中間設計(ji)成軸向(xiang)剖(pou)分式(shi),用螺栓固定(ding)連(lian)接。
