產品概況(kuang)
回轉式三筒烘干(gan)(gan)(gan)(gan)機(ji)改進(jin)原(yuan)單(dan)(dan)筒烘干(gan)(gan)(gan)(gan)機(ji)內(nei)部(bu)結構(gou),增加入(ru)機(ji)前濕料(liao)(liao)的(de)(de)預烘干(gan)(gan)(gan)(gan)和延長濕料(liao)(liao)在(zai)機(ji)內(nei)烘干(gan)(gan)(gan)(gan)時間,再(zai)加上密封、保溫以(yi)及合理(li)的(de)(de)配套(tao)措施(shi),使烘干(gan)(gan)(gan)(gan)機(ji)生(sheng)產能力與原(yuan)單(dan)(dan)筒式烘干(gan)(gan)(gan)(gan)機(ji)相比,提高(gao)48-80%,單(dan)(dan)位容(rong)積蒸發強(qiang)度可(ke)達120-180kg/m3,標準煤耗僅為6-8kg/t。其技術先進(jin)、運行參數(shu)合理(li),操(cao)作簡單(dan)(dan)可(ke)行,廣泛(fan)應(ying)用于各個行業的(de)(de)礦渣、粘(zhan)土、煤。
產品結構(gou)
三筒(tong)(tong)烘干(gan)機是通過(guo)對單(dan)筒(tong)(tong)烘干(gan)機的單(dan)筒(tong)(tong)體改為套疊在(zai)一(yi)起的三筒(tong)(tong),以縮(suo)短烘干(gan)機體的外(wai)形(xing)尺寸。該機工作(zuo)時,物(wu)料和熱氣流依次進入內至外(wai)筒(tong)(tong)體,在(zai)機體Z形(xing)往復折流后(hou),充分利用熱能烘干(gan)物(wu)料后(hou)再(zai)卸出。
烘干(gan)機(ji)筒(tong)(tong)體(ti)部(bu)分由三個(ge)同軸水平放置(zhi)的(de)內、中(zhong)、外筒(tong)(tong)套疊組成,這(zhe)就使筒(tong)(tong)體(ti)的(de)截面(mian)得到充分的(de)利(li)用。其筒(tong)(tong)體(ti)外形總長度(du)約為與之相當的(de)單筒(tong)(tong)的(de)30-35%。從而大幅度(du)地減少(shao)占地面(mian)積和廠房建筑面(mian)積。
該(gai)機的支(zhi)承(cheng)裝置,是在外筒上輪(lun)帶與(yu)托(tuo)(tuo)輪(lun)支(zhi)承(cheng),由電機直接帶動托(tuo)(tuo)輪(lun)。通過托(tuo)(tuo)輪(lun)與(yu)輪(lun)帶摩擦(ca),使筒體(ti)轉動。該(gai)機總體(ti)結構緊湊(cou)、合理、簡(jian)單,為(wei)便于磨(mo)損件的檢修更(geng)換,在中間設(she)計成軸(zhou)向剖分式,用(yong)螺(luo)栓固定連(lian)接。
工(gong)作原理(li)
