產品概況
回轉式(shi)三筒(tong)(tong)烘(hong)(hong)干(gan)(gan)機(ji)改進原單筒(tong)(tong)烘(hong)(hong)干(gan)(gan)機(ji)內部結構，增加(jia)入機(ji)前濕料的預烘(hong)(hong)干(gan)(gan)和延(yan)長濕料在機(ji)內烘(hong)(hong)干(gan)(gan)時間，再加(jia)上密封、保(bao)溫(wen)以及合(he)理(li)的配(pei)套措施，使烘(hong)(hong)干(gan)(gan)機(ji)生產能力與原單筒(tong)(tong)式(shi)烘(hong)(hong)干(gan)(gan)機(ji)相比，提高48-80%，單位(wei)容(rong)積蒸發強度可達120-180kg/m3，標準(zhun)煤耗(hao)僅為(wei)6-8kg/t。其技(ji)術先進、運行(xing)(xing)參數合(he)理(li)，操作(zuo)簡單可行(xing)(xing)，廣泛應用(yong)于(yu)各個行(xing)(xing)業的礦(kuang)渣(zha)、粘(zhan)土、煤。
產品結構
三筒(tong)(tong)(tong)烘(hong)干機(ji)是通過對單筒(tong)(tong)(tong)烘(hong)干機(ji)的(de)單筒(tong)(tong)(tong)體改為套疊在一起的(de)三筒(tong)(tong)(tong)，以縮(suo)短(duan)烘(hong)干機(ji)體的(de)外(wai)形尺寸。該機(ji)工作時(shi)，物(wu)(wu)料和熱氣(qi)流(liu)依(yi)次進入內至外(wai)筒(tong)(tong)(tong)體，在機(ji)體Z形往復折流(liu)后(hou)，充分利用(yong)熱能烘(hong)干物(wu)(wu)料后(hou)再卸出。
烘干機筒(tong)(tong)體部分(fen)由三個同軸水平放(fang)置的(de)(de)內、中(zhong)、外(wai)筒(tong)(tong)套疊組成，這就使(shi)筒(tong)(tong)體的(de)(de)截(jie)面(mian)得(de)到充分(fen)的(de)(de)利用。其筒(tong)(tong)體外(wai)形(xing)總長度約為與(yu)之相當的(de)(de)單筒(tong)(tong)的(de)(de)30-35%。從而(er)大幅(fu)度地減少(shao)占地面(mian)積和廠房建筑面(mian)積。
該機的(de)支承(cheng)裝置，是在(zai)外筒上輪(lun)(lun)帶(dai)與(yu)托(tuo)輪(lun)(lun)支承(cheng)，由電機直(zhi)接帶(dai)動(dong)托(tuo)輪(lun)(lun)。通過托(tuo)輪(lun)(lun)與(yu)輪(lun)(lun)帶(dai)摩(mo)擦(ca)，使筒體轉動(dong)。該機總體結構緊(jin)湊、合理、簡單，為便于磨損件(jian)的(de)檢修更換，在(zai)中間(jian)設計成軸(zhou)向剖分式(shi)，用(yong)螺栓(shuan)固定連接。
