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(gan)機筒(tong)體部分由(you)三個(ge)同軸(zhou)水平(ping)放置的(de)內、中、外(wai)筒(tong)套(tao)疊(die)組成,這就使筒(tong)體的(de)截面得到充分的(de)利用。其筒(tong)體外(wai)形總(zong)長度約(yue)為與(yu)之相當的(de)單(dan)筒(tong)的(de)30-35%。從而大幅度地(di)(di)減少占地(di)(di)面積(ji)和廠(chang)房建(jian)筑面積(ji)。
該機的支承裝置,是在外筒上(shang)輪(lun)(lun)(lun)帶與(yu)托輪(lun)(lun)(lun)支承,由電機直(zhi)接帶動(dong)托輪(lun)(lun)(lun)。通過托輪(lun)(lun)(lun)與(yu)輪(lun)(lun)(lun)帶摩擦,使筒體(ti)轉動(dong)。該機總(zong)體(ti)結構緊(jin)湊、合理、簡單(dan),為便于磨損件的檢修更(geng)換,在中間設計成軸向剖分式,用(yong)螺栓固定連接。
