產品結構
三筒(tong)(tong)烘(hong)干機是通過對(dui)單筒(tong)(tong)烘(hong)干機的(de)單筒(tong)(tong)體改為套疊在一起的(de)三筒(tong)(tong)，以縮短烘(hong)干機體的(de)外(wai)形尺寸(cun)。該機工作時(shi)，物(wu)料(liao)(liao)和熱(re)氣流(liu)依次(ci)進入內(nei)至(zhi)外(wai)筒(tong)(tong)體，在機體Z形往復(fu)折(zhe)流(liu)后，充分利(li)用熱(re)能烘(hong)干物(wu)料(liao)(liao)后再(zai)卸出。
烘干(gan)機筒(tong)(tong)體部(bu)分由三個同軸水(shui)平放置(zhi)的內(nei)、中、外筒(tong)(tong)套疊組成，這就(jiu)使筒(tong)(tong)體的截面得到充分的利(li)用(yong)。其(qi)筒(tong)(tong)體外形總長度約為與之相當的單筒(tong)(tong)的30-35%。從而大(da)幅度地減少占地面積和(he)廠房建(jian)筑面積。
該機(ji)的支承(cheng)裝置(zhi)，是在(zai)外筒上輪(lun)帶與托輪(lun)支承(cheng)，由電機(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)總體結構緊湊、合理、簡單，為便于磨(mo)損件的檢修更(geng)換(huan)，在(zai)中間(jian)設計成(cheng)軸向剖分式，用螺栓固定(ding)連接。
