產品概況
回轉式三筒烘(hong)(hong)干(gan)(gan)機(ji)改進(jin)原(yuan)單筒烘(hong)(hong)干(gan)(gan)機(ji)內部結構，增加入機(ji)前濕料的預烘(hong)(hong)干(gan)(gan)和延長濕料在機(ji)內烘(hong)(hong)干(gan)(gan)時(shi)間，再加上密封(feng)、保(bao)溫以及合理的配套(tao)措施，使烘(hong)(hong)干(gan)(gan)機(ji)生(sheng)產能力與原(yuan)單筒式烘(hong)(hong)干(gan)(gan)機(ji)相(xiang)比，提高48-80%，單位(wei)容積蒸發(fa)強(qiang)度(du)可(ke)達120-180kg/m3，標準煤耗(hao)僅為6-8kg/t。其技術先進(jin)、運行參數合理，操作簡單可(ke)行，廣泛(fan)應用于各個行業的礦渣、粘土(tu)、煤。
產品結(jie)構
三筒(tong)烘(hong)干(gan)機(ji)(ji)是(shi)通過(guo)對單筒(tong)烘(hong)干(gan)機(ji)(ji)的單筒(tong)體改為套(tao)疊(die)在(zai)一起的三筒(tong)，以縮短(duan)烘(hong)干(gan)機(ji)(ji)體的外(wai)形尺寸(cun)。該(gai)機(ji)(ji)工作時，物(wu)料和熱(re)氣流(liu)依次(ci)進入(ru)內至外(wai)筒(tong)體，在(zai)機(ji)(ji)體Z形往復折流(liu)后，充分利用熱(re)能烘(hong)干(gan)物(wu)料后再卸出(chu)。
烘干機筒體部(bu)分(fen)由三個(ge)同軸(zhou)水平放置的內(nei)、中、外筒套疊組(zu)成，這就(jiu)使(shi)筒體的截面(mian)得到充分(fen)的利用。其筒體外形總長度約為與之相當的單筒的30-35%。從而大幅度地(di)減少占地(di)面(mian)積和(he)廠房建筑面(mian)積。
該機的支(zhi)承裝置(zhi)，是在(zai)(zai)外筒上輪(lun)(lun)(lun)帶與(yu)托(tuo)輪(lun)(lun)(lun)支(zhi)承，由電機直接帶動托(tuo)輪(lun)(lun)(lun)。通過(guo)托(tuo)輪(lun)(lun)(lun)與(yu)輪(lun)(lun)(lun)帶摩擦(ca)，使筒體轉動。該機總體結構緊湊、合理、簡單，為便(bian)于磨損件的檢修更(geng)換，在(zai)(zai)中間設計(ji)成軸向剖分(fen)式，用(yong)螺栓固定連接。
