產品概(gai)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。
產品結構(gou)
三筒(tong)式烘(hong)干(gan)(gan)機是通過(guo)對單筒(tong)烘(hong)干(gan)(gan)機的單筒(tong)體改為(wei)套疊(die)在一起(qi)的三筒(tong),以縮短烘(hong)干(gan)(gan)機體的外(wai)形(xing)尺寸。該機工作(zuo)時(shi),物料(liao)和熱(re)氣流(liu)依次進(jin)入(ru)內至外(wai)筒(tong)體,在機體Z形(xing)往復折流(liu)后(hou),充分利用熱(re)能烘(hong)干(gan)(gan)物料(liao)后(hou)再卸出。
烘(hong)干機筒(tong)(tong)(tong)體(ti)(ti)部分(fen)由三個同軸水(shui)平放置的(de)內、中、外筒(tong)(tong)(tong)套疊組成,這就使筒(tong)(tong)(tong)體(ti)(ti)的(de)截面得到充分(fen)的(de)利用。其(qi)筒(tong)(tong)(tong)體(ti)(ti)外形總長度約為與之相當的(de)單筒(tong)(tong)(tong)的(de)30-35%。從而大幅度地減少占地面積(ji)(ji)和(he)廠房建筑面積(ji)(ji)。
該(gai)機的(de)支承(cheng)(cheng)裝(zhuang)置(zhi),是在外筒上輪帶(dai)與(yu)(yu)托(tuo)輪支承(cheng)(cheng),由電機直接帶(dai)動(dong)托(tuo)輪。通過托(tuo)輪與(yu)(yu)輪帶(dai)摩擦,使筒體轉動(dong)。該(gai)機總體結(jie)構緊(jin)湊(cou)、合理(li)、簡(jian)單,為便于磨損件的(de)檢修更換,在中間設(she)計成軸向剖(pou)分式,用(yong)螺栓固定(ding)連接。
