產品(pin)概況
回(hui)轉式三筒烘(hong)干(gan)機(ji)改進原單筒烘(hong)干(gan)機(ji)內(nei)部結構,增(zeng)加(jia)入機(ji)前濕料(liao)的(de)預烘(hong)干(gan)和延長濕料(liao)在(zai)機(ji)內(nei)烘(hong)干(gan)時間,再加(jia)上密(mi)封、保溫(wen)以(yi)及合理(li)的(de)配套措施(shi),使(shi)烘(hong)干(gan)機(ji)生(sheng)產能力與原單筒式烘(hong)干(gan)機(ji)相比(bi),提高48-80%,單位容積蒸發強(qiang)度可(ke)達120-180kg/m3,標準煤(mei)耗僅為6-8kg/t。其技術先進、運行(xing)(xing)參數合理(li),操(cao)作簡單可(ke)行(xing)(xing),廣泛應(ying)用于各個行(xing)(xing)業的(de)礦渣、粘(zhan)土(tu)、煤(mei)。
產品結構
三筒(tong)(tong)烘(hong)干(gan)機(ji)是通過對單筒(tong)(tong)烘(hong)干(gan)機(ji)的(de)單筒(tong)(tong)體(ti)改為套疊在(zai)一起(qi)的(de)三筒(tong)(tong),以(yi)縮短烘(hong)干(gan)機(ji)體(ti)的(de)外形尺寸(cun)。該機(ji)工作時,物(wu)(wu)料(liao)和熱(re)氣流(liu)依次進入(ru)內至外筒(tong)(tong)體(ti),在(zai)機(ji)體(ti)Z形往復折(zhe)流(liu)后(hou),充分利用(yong)熱(re)能(neng)烘(hong)干(gan)物(wu)(wu)料(liao)后(hou)再卸出。
烘干機筒(tong)體(ti)(ti)(ti)部(bu)分由三個同軸(zhou)水平放(fang)置(zhi)的(de)內、中(zhong)、外筒(tong)套疊組(zu)成,這(zhe)就使筒(tong)體(ti)(ti)(ti)的(de)截面得到充(chong)分的(de)利(li)用。其筒(tong)體(ti)(ti)(ti)外形總長度約為與之(zhi)相(xiang)當(dang)的(de)單筒(tong)的(de)30-35%。從(cong)而大(da)幅度地減少占地面積(ji)和廠房建(jian)筑面積(ji)。
該(gai)機(ji)的(de)支承(cheng)裝置,是在(zai)外筒(tong)上輪(lun)帶(dai)與(yu)托(tuo)輪(lun)支承(cheng),由電(dian)機(ji)直接(jie)帶(dai)動托(tuo)輪(lun)。通過托(tuo)輪(lun)與(yu)輪(lun)帶(dai)摩擦,使筒(tong)體轉動。該(gai)機(ji)總(zong)體結構緊湊(cou)、合理、簡單,為便于磨損件的(de)檢修更換,在(zai)中(zhong)間設計成(cheng)軸(zhou)向剖(pou)分式,用螺栓固定連接(jie)。
工作(zuo)原理
