產品概況
回轉式(shi)三(san)筒(tong)烘(hong)干(gan)機(ji)(ji)(ji)改進原單(dan)筒(tong)烘(hong)干(gan)機(ji)(ji)(ji)內(nei)部結構(gou)，增加入(ru)機(ji)(ji)(ji)前濕料的(de)預烘(hong)干(gan)和(he)延(yan)長濕料在機(ji)(ji)(ji)內(nei)烘(hong)干(gan)時間，再(zai)加上(shang)密封、保溫(wen)以及合理的(de)配套(tao)措施，使烘(hong)干(gan)機(ji)(ji)(ji)生產能(neng)力(li)與原單(dan)筒(tong)式(shi)烘(hong)干(gan)機(ji)(ji)(ji)相比，提高48-80%，單(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(qi)技術先進、運行(xing)參數合理，操作簡(jian)單(dan)可(ke)行(xing)，廣泛應(ying)用于各(ge)個行(xing)業的(de)礦渣、粘土、煤。
產品結構
三筒(tong)烘干機(ji)是通過對單(dan)(dan)筒(tong)烘干機(ji)的單(dan)(dan)筒(tong)體改(gai)為套(tao)疊(die)在一起的三筒(tong)，以縮短烘干機(ji)體的外形(xing)尺寸。該(gai)機(ji)工作時(shi)，物料(liao)和(he)熱(re)氣流依次進入內(nei)至外筒(tong)體，在機(ji)體Z形(xing)往(wang)復折流后，充分利用熱(re)能(neng)烘干物料(liao)后再卸出。
烘(hong)干(gan)機筒(tong)體(ti)部(bu)分由三(san)個同軸水平放置的(de)(de)內、中、外筒(tong)套疊組成，這就使筒(tong)體(ti)的(de)(de)截(jie)面得(de)到充分的(de)(de)利用(yong)。其筒(tong)體(ti)外形總長度約為(wei)與之相當的(de)(de)單筒(tong)的(de)(de)30-35%。從而(er)大幅度地減少占地面積(ji)和廠(chang)房建筑面積(ji)。
該機(ji)的支(zhi)承裝置，是在外筒(tong)上輪(lun)(lun)帶(dai)與(yu)托輪(lun)(lun)支(zhi)承，由電機(ji)直接帶(dai)動托輪(lun)(lun)。通過托輪(lun)(lun)與(yu)輪(lun)(lun)帶(dai)摩(mo)擦，使筒(tong)體(ti)轉動。該機(ji)總體(ti)結構緊湊、合理(li)、簡單，為(wei)便(bian)于磨(mo)損(sun)件的檢修更換，在中(zhong)間設計成軸(zhou)向剖分式，用螺栓(shuan)固(gu)定連接。
