產品結(jie)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。
烘干機筒(tong)體(ti)部(bu)分由(you)三個同軸水平放(fang)置的內(nei)、中、外筒(tong)套疊組成(cheng),這就使筒(tong)體(ti)的截面(mian)(mian)得到充分的利(li)用。其筒(tong)體(ti)外形總長(chang)度(du)約為與之(zhi)相當的單(dan)筒(tong)的30-35%。從而大幅度(du)地減少(shao)占(zhan)地面(mian)(mian)積和廠房建筑(zhu)面(mian)(mian)積。
該機(ji)的(de)支(zhi)承裝置,是在外筒上輪帶(dai)與托(tuo)(tuo)輪支(zhi)承,由電機(ji)直接帶(dai)動(dong)托(tuo)(tuo)輪。通過托(tuo)(tuo)輪與輪帶(dai)摩擦,使筒體轉動(dong)。該機(ji)總(zong)體結構緊湊、合理、簡(jian)單(dan),為便于(yu)磨損件的(de)檢修更換(huan),在中間設計成軸向(xiang)剖分式,用螺(luo)栓(shuan)固定連接。
工作原理(li)
