產(chan)品概況
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)式烘干(gan)機(ji)是通過對單筒(tong)(tong)烘干(gan)機(ji)的單筒(tong)(tong)體(ti)(ti)改為套疊(die)在一(yi)起的三筒(tong)(tong),以縮短烘干(gan)機(ji)體(ti)(ti)的外形尺寸。該機(ji)工(gong)作時,物(wu)料(liao)和熱(re)氣流依次進入內至外筒(tong)(tong)體(ti)(ti),在機(ji)體(ti)(ti)Z形往復折流后,充分(fen)利用(yong)熱(re)能(neng)烘干(gan)物(wu)料(liao)后再卸出。
烘(hong)干機筒(tong)體(ti)部分由(you)三個同軸水平放置(zhi)的(de)內、中(zhong)、外筒(tong)套(tao)疊組成,這就使筒(tong)體(ti)的(de)截(jie)面(mian)得到(dao)充(chong)分的(de)利用。其筒(tong)體(ti)外形總長度約為與之相當的(de)單筒(tong)的(de)30-35%。從而大幅度地(di)減少占地(di)面(mian)積和廠房建(jian)筑(zhu)面(mian)積。
該(gai)機(ji)的(de)支(zhi)承裝(zhuang)置(zhi),是在(zai)外筒上輪(lun)帶(dai)與(yu)托(tuo)輪(lun)支(zhi)承,由電機(ji)直接帶(dai)動托(tuo)輪(lun)。通過(guo)托(tuo)輪(lun)與(yu)輪(lun)帶(dai)摩擦,使筒體(ti)轉動。該(gai)機(ji)總體(ti)結(jie)構緊湊、合(he)理、簡單,為(wei)便(bian)于(yu)磨損件(jian)的(de)檢(jian)修(xiu)更換,在(zai)中間(jian)設計成(cheng)軸(zhou)向(xiang)剖分式,用(yong)螺栓固(gu)定連接。
