產品概況(kuang)
回轉式(shi)三筒烘(hong)干(gan)(gan)機(ji)改進(jin)原(yuan)單(dan)筒烘(hong)干(gan)(gan)機(ji)內部結構,增加入機(ji)前濕(shi)料的預烘(hong)干(gan)(gan)和(he)延長(chang)濕(shi)料在(zai)機(ji)內烘(hong)干(gan)(gan)時間,再加上密封、保溫以及合理(li)的配套措施(shi),使烘(hong)干(gan)(gan)機(ji)生產能(neng)力與原(yuan)單(dan)筒式(shi)烘(hong)干(gan)(gan)機(ji)相比(bi),提(ti)高48-80%,單(dan)位容積(ji)蒸發強度可達120-180kg/m3,標準煤耗(hao)僅為(wei)6-8kg/t。其技(ji)術先進(jin)、運行(xing)參數合理(li),操作簡單(dan)可行(xing),廣(guang)泛應用于(yu)各個行(xing)業的礦(kuang)渣、粘土、煤。
產品結(jie)構(gou)
三(san)筒(tong)(tong)烘(hong)干(gan)機(ji)是通過對單筒(tong)(tong)烘(hong)干(gan)機(ji)的(de)單筒(tong)(tong)體(ti)改(gai)為套疊在(zai)一起的(de)三(san)筒(tong)(tong),以(yi)縮短烘(hong)干(gan)機(ji)體(ti)的(de)外形尺(chi)寸(cun)。該(gai)機(ji)工作時,物(wu)料和熱氣流依次(ci)進(jin)入內至(zhi)外筒(tong)(tong)體(ti),在(zai)機(ji)體(ti)Z形往復折流后(hou),充分利用熱能烘(hong)干(gan)物(wu)料后(hou)再卸出。
烘(hong)干(gan)機筒(tong)(tong)體(ti)部(bu)分由三個同軸水平放置的內、中、外(wai)筒(tong)(tong)套(tao)疊組(zu)成,這就使(shi)筒(tong)(tong)體(ti)的截(jie)面得(de)到充分的利(li)用。其筒(tong)(tong)體(ti)外(wai)形(xing)總長度(du)約(yue)為與之(zhi)相當的單筒(tong)(tong)的30-35%。從而大幅度(du)地減少占地面積(ji)和廠房建(jian)筑面積(ji)。
該機的支承裝置(zhi),是在外(wai)筒上輪(lun)帶(dai)與(yu)托(tuo)輪(lun)支承,由電機直接帶(dai)動托(tuo)輪(lun)。通過托(tuo)輪(lun)與(yu)輪(lun)帶(dai)摩擦,使筒體轉(zhuan)動。該機總體結構(gou)緊湊、合理、簡單,為便于(yu)磨損件的檢修(xiu)更換,在中(zhong)間設計成軸向(xiang)剖分(fen)式,用螺(luo)栓(shuan)固定連(lian)接。
