產品(pin)概況(kuang)
回轉(zhuan)式三筒烘(hong)(hong)干(gan)(gan)機(ji)(ji)(ji)(ji)改(gai)進(jin)原單筒烘(hong)(hong)干(gan)(gan)機(ji)(ji)(ji)(ji)內(nei)部結構，增(zeng)加(jia)入機(ji)(ji)(ji)(ji)前濕料(liao)的(de)預(yu)烘(hong)(hong)干(gan)(gan)和延長濕料(liao)在機(ji)(ji)(ji)(ji)內(nei)烘(hong)(hong)干(gan)(gan)時間(jian)，再加(jia)上密封、保溫以及(ji)合理(li)的(de)配套(tao)措施，使烘(hong)(hong)干(gan)(gan)機(ji)(ji)(ji)(ji)生產(chan)能力與原單筒式烘(hong)(hong)干(gan)(gan)機(ji)(ji)(ji)(ji)相比，提(ti)高48-80%，單位容(rong)積蒸發強度可(ke)達120-180kg/m3，標準(zhun)煤耗僅為6-8kg/t。其技術先(xian)進(jin)、運行參數(shu)合理(li)，操(cao)作(zuo)簡單可(ke)行，廣泛應用于各個行業(ye)的(de)礦(kuang)渣、粘(zhan)土、煤。
產品(pin)結構
三(san)筒(tong)(tong)烘(hong)(hong)干(gan)機(ji)(ji)是通過對單(dan)筒(tong)(tong)烘(hong)(hong)干(gan)機(ji)(ji)的(de)單(dan)筒(tong)(tong)體(ti)改為(wei)套疊(die)在(zai)一起的(de)三(san)筒(tong)(tong)，以縮短烘(hong)(hong)干(gan)機(ji)(ji)體(ti)的(de)外形(xing)尺(chi)寸(cun)。該機(ji)(ji)工作(zuo)時，物(wu)(wu)料和(he)熱(re)氣流依次進入內至外筒(tong)(tong)體(ti)，在(zai)機(ji)(ji)體(ti)Z形(xing)往(wang)復(fu)折流后，充分利(li)用熱(re)能烘(hong)(hong)干(gan)物(wu)(wu)料后再卸出。
烘干機筒(tong)體部分(fen)由(you)三個同軸水平(ping)放置的(de)內、中、外(wai)筒(tong)套疊組(zu)成，這就使筒(tong)體的(de)截(jie)面(mian)得到充分(fen)的(de)利用。其筒(tong)體外(wai)形(xing)總(zong)長(chang)度約為與(yu)之相當的(de)單筒(tong)的(de)30-35%。從而大幅度地減少(shao)占地面(mian)積(ji)(ji)和廠(chang)房建筑面(mian)積(ji)(ji)。
該機的支(zhi)承(cheng)裝置，是(shi)在外筒上輪(lun)帶(dai)與托(tuo)輪(lun)支(zhi)承(cheng)，由(you)電機直接帶(dai)動托(tuo)輪(lun)。通(tong)過托(tuo)輪(lun)與輪(lun)帶(dai)摩擦，使筒體轉動。該機總體結構緊湊(cou)、合理、簡單，為便(bian)于磨損件(jian)的檢修更換，在中間設計(ji)成(cheng)軸(zhou)向剖分式，用(yong)螺栓固定連(lian)接。
