產品概況(kuang)
回轉式三筒烘干機改進原單筒烘干機內部結構，增加入機前濕料的預烘干和延長濕料在機內烘干時間，再加上密封、保溫以及合理的配套措施，使烘干機生產能力與原單筒式烘干機相比，提高48-80%，單位容積蒸發強度可達120-180kg/m3，標準煤耗僅為6-8kg/t。其技術先進、運行參數合理，操作簡單可行，廣泛應用于各個行業的礦渣、粘土、煤。
產(chan)品結構
三筒(tong)(tong)式烘(hong)干(gan)機(ji)是通過對單(dan)(dan)筒(tong)(tong)烘(hong)干(gan)機(ji)的(de)單(dan)(dan)筒(tong)(tong)體(ti)改為(wei)套疊在(zai)一起的(de)三筒(tong)(tong)，以縮短烘(hong)干(gan)機(ji)體(ti)的(de)外形(xing)尺寸。該機(ji)工作時(shi)，物料(liao)和熱(re)氣流依次進入內至外筒(tong)(tong)體(ti)，在(zai)機(ji)體(ti)Z形(xing)往復折流后，充分利用熱(re)能烘(hong)干(gan)物料(liao)后再卸出(chu)。
烘(hong)干機筒(tong)(tong)(tong)體部分(fen)由三個(ge)同軸水平放置(zhi)的(de)內、中、外筒(tong)(tong)(tong)套疊組成(cheng)，這就使(shi)筒(tong)(tong)(tong)體的(de)截(jie)面得到充(chong)分(fen)的(de)利用。其筒(tong)(tong)(tong)體外形(xing)總(zong)長度約為(wei)與之相(xiang)當的(de)單筒(tong)(tong)(tong)的(de)30-35%。從而大幅度地減少占地面積(ji)和廠房(fang)建筑面積(ji)。
該機(ji)的支承(cheng)裝置，是在外筒(tong)上輪(lun)(lun)帶與托輪(lun)(lun)支承(cheng)，由電機(ji)直接帶動(dong)托輪(lun)(lun)。通過托輪(lun)(lun)與輪(lun)(lun)帶摩擦，使筒(tong)體轉動(dong)。該機(ji)總體結(jie)構緊湊、合理(li)、簡單，為便(bian)于磨損件的檢修(xiu)更換，在中間設計(ji)成軸(zhou)向剖分式，用螺栓(shuan)固定連接。
