產品概況
回轉式三筒烘干機改進原單筒烘干機內部結構,增加入機前濕料的預烘干和延長濕料在機內烘干時間,再加上密封、保溫以及合理的配套措施,使烘干機生產能力與原單筒式烘干機相比,提高48-80%,單位容積蒸發強度可達120-180kg/m3,標準煤耗僅為6-8kg/t。其技術先進、運行參數合理,操作簡單可行,廣泛應用于各個行業的礦渣、粘土、煤。
產品(pin)結構
三(san)筒(tong)式烘(hong)(hong)干(gan)機(ji)是通(tong)過對單(dan)筒(tong)烘(hong)(hong)干(gan)機(ji)的(de)單(dan)筒(tong)體(ti)(ti)(ti)改為套疊在(zai)一起的(de)三(san)筒(tong),以(yi)縮短烘(hong)(hong)干(gan)機(ji)體(ti)(ti)(ti)的(de)外形尺寸。該機(ji)工作(zuo)時,物料(liao)和熱氣流(liu)依次進(jin)入(ru)內(nei)至外筒(tong)體(ti)(ti)(ti),在(zai)機(ji)體(ti)(ti)(ti)Z形往復折流(liu)后,充分利用熱能烘(hong)(hong)干(gan)物料(liao)后再(zai)卸(xie)出。
烘干(gan)機筒體(ti)部(bu)分由三(san)個同(tong)軸水平(ping)放(fang)置的內、中、外筒套疊組(zu)成,這就使筒體(ti)的截面得(de)到充(chong)分的利用。其筒體(ti)外形總長度約為與之相(xiang)當的單筒的30-35%。從而大幅度地減少占地面積和廠房建筑(zhu)面積。
該機(ji)的支承裝置,是在外筒上輪(lun)帶(dai)與(yu)托(tuo)輪(lun)支承,由電機(ji)直接帶(dai)動托(tuo)輪(lun)。通過托(tuo)輪(lun)與(yu)輪(lun)帶(dai)摩擦(ca),使筒體(ti)轉動。該機(ji)總體(ti)結(jie)構緊湊(cou)、合理(li)、簡單,為便于磨損件的檢修更換(huan),在中間設計成軸(zhou)向(xiang)剖分式(shi),用螺栓固定(ding)連接。
