產品(pin)概(gai)況(kuang)
回轉式三筒(tong)烘(hong)(hong)干(gan)機(ji)(ji)改進(jin)原單(dan)筒(tong)烘(hong)(hong)干(gan)機(ji)(ji)內部結構(gou)，增加(jia)入機(ji)(ji)前(qian)濕料的(de)預烘(hong)(hong)干(gan)和延長濕料在機(ji)(ji)內烘(hong)(hong)干(gan)時間，再加(jia)上密封、保溫(wen)以(yi)及(ji)合理(li)的(de)配套措施，使(shi)烘(hong)(hong)干(gan)機(ji)(ji)生產能(neng)力與原單(dan)筒(tong)式烘(hong)(hong)干(gan)機(ji)(ji)相比，提(ti)高48-80%，單(dan)位容(rong)積蒸發強度可達120-180kg/m3，標(biao)準(zhun)煤耗(hao)僅為(wei)6-8kg/t。其技術(shu)先進(jin)、運行參數(shu)合理(li)，操(cao)作(zuo)簡單(dan)可行，廣(guang)泛應(ying)用于各個行業的(de)礦渣、粘(zhan)土、煤。
產(chan)品結(jie)構(gou)
三(san)筒(tong)(tong)烘干(gan)(gan)機(ji)是通(tong)過對單筒(tong)(tong)烘干(gan)(gan)機(ji)的單筒(tong)(tong)體改(gai)為(wei)套疊在一(yi)起的三(san)筒(tong)(tong)，以縮短烘干(gan)(gan)機(ji)體的外形(xing)尺(chi)寸。該機(ji)工(gong)作時，物料(liao)和熱(re)氣流(liu)依次進(jin)入內(nei)至(zhi)外筒(tong)(tong)體，在機(ji)體Z形(xing)往(wang)復折流(liu)后，充分(fen)利用熱(re)能烘干(gan)(gan)物料(liao)后再(zai)卸出(chu)。
烘干機筒體(ti)部分(fen)由三(san)個同軸水平(ping)放置(zhi)的(de)內、中、外筒套疊組成(cheng)，這(zhe)就使筒體(ti)的(de)截面(mian)得到充分(fen)的(de)利用。其筒體(ti)外形(xing)總長(chang)度約為(wei)與(yu)之相當的(de)單筒的(de)30-35%。從而大幅度地減少占地面(mian)積和廠房建筑面(mian)積。
該(gai)機(ji)的支承(cheng)裝置，是(shi)在(zai)外筒上輪(lun)(lun)帶(dai)與托輪(lun)(lun)支承(cheng)，由電機(ji)直接(jie)帶(dai)動(dong)托輪(lun)(lun)。通(tong)過托輪(lun)(lun)與輪(lun)(lun)帶(dai)摩擦，使筒體轉動(dong)。該(gai)機(ji)總體結構緊(jin)湊、合理、簡單，為便于(yu)磨損件的檢修更換，在(zai)中間設(she)計成(cheng)軸向(xiang)剖分式，用螺栓固定連接(jie)。
