產品(pin)概況
回轉式三筒(tong)烘(hong)干(gan)(gan)機改進(jin)(jin)原(yuan)單(dan)(dan)筒(tong)烘(hong)干(gan)(gan)機內部(bu)結構，增加入機前(qian)濕料的(de)預烘(hong)干(gan)(gan)和(he)延長濕料在機內烘(hong)干(gan)(gan)時間，再加上(shang)密封(feng)、保溫以及合(he)理的(de)配套措施(shi)，使烘(hong)干(gan)(gan)機生產能(neng)力與原(yuan)單(dan)(dan)筒(tong)式烘(hong)干(gan)(gan)機相比，提高48-80%，單(dan)(dan)位(wei)容積蒸發強度可達120-180kg/m3，標準煤耗僅為(wei)6-8kg/t。其(qi)技術先進(jin)(jin)、運行參數合(he)理，操作簡單(dan)(dan)可行，廣泛應用于各個行業(ye)的(de)礦(kuang)渣、粘(zhan)土(tu)、煤。
產(chan)品結構
三筒(tong)烘(hong)(hong)干(gan)機(ji)(ji)是通(tong)過對單(dan)筒(tong)烘(hong)(hong)干(gan)機(ji)(ji)的單(dan)筒(tong)體(ti)改為(wei)套疊(die)在(zai)一起的三筒(tong)，以縮(suo)短烘(hong)(hong)干(gan)機(ji)(ji)體(ti)的外形尺寸。該機(ji)(ji)工作(zuo)時，物(wu)料和熱氣流依次(ci)進(jin)入(ru)內(nei)至外筒(tong)體(ti)，在(zai)機(ji)(ji)體(ti)Z形往復折(zhe)流后，充(chong)分利用(yong)熱能(neng)烘(hong)(hong)干(gan)物(wu)料后再卸出。
烘干機筒(tong)(tong)體(ti)部分由(you)三個同(tong)軸水平(ping)放置的(de)內、中、外筒(tong)(tong)套疊(die)組成，這就使筒(tong)(tong)體(ti)的(de)截(jie)面(mian)(mian)得到充分的(de)利(li)用(yong)。其筒(tong)(tong)體(ti)外形總長度(du)(du)約為與之相當的(de)單筒(tong)(tong)的(de)30-35%。從(cong)而大幅度(du)(du)地減(jian)少占(zhan)地面(mian)(mian)積(ji)和廠房建(jian)筑(zhu)面(mian)(mian)積(ji)。
該機(ji)(ji)的(de)支承(cheng)(cheng)裝置(zhi)，是在外筒上輪(lun)(lun)(lun)帶與(yu)托(tuo)輪(lun)(lun)(lun)支承(cheng)(cheng)，由電機(ji)(ji)直接帶動托(tuo)輪(lun)(lun)(lun)。通過托(tuo)輪(lun)(lun)(lun)與(yu)輪(lun)(lun)(lun)帶摩擦，使筒體轉動。該機(ji)(ji)總體結構緊湊(cou)、合理、簡(jian)單，為便(bian)于磨(mo)損(sun)件的(de)檢(jian)修更換，在中間設計成軸向(xiang)剖分(fen)式，用(yong)螺(luo)栓固(gu)定連接。
工作原(yuan)理
