產品結構
大型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。
烘干機筒(tong)體部(bu)分由三個(ge)同軸水平(ping)放置的內(nei)、中、外(wai)筒(tong)套疊(die)組(zu)成,這(zhe)就(jiu)使筒(tong)體的截面得到(dao)充(chong)分的利(li)用。其筒(tong)體外(wai)形總長(chang)度(du)約為與(yu)之(zhi)相當的單(dan)筒(tong)的30-35%。從(cong)而(er)大幅度(du)地減少占地面積和(he)廠(chang)房建筑面積。
該(gai)(gai)機的(de)支承(cheng)裝置,是在(zai)外筒(tong)上(shang)輪(lun)(lun)帶(dai)與托(tuo)輪(lun)(lun)支承(cheng),由(you)電(dian)機直接(jie)帶(dai)動托(tuo)輪(lun)(lun)。通過托(tuo)輪(lun)(lun)與輪(lun)(lun)帶(dai)摩擦,使筒(tong)體轉動。該(gai)(gai)機總體結構緊湊、合(he)理、簡單(dan),為便于磨損件的(de)檢修(xiu)更換,在(zai)中間設(she)計成(cheng)軸向剖(pou)分式,用螺栓固定連(lian)接(jie)。
