產(chan)品概(gai)況(kuang)
回轉式(shi)(shi)三(san)筒烘(hong)(hong)(hong)干(gan)(gan)機(ji)改進原(yuan)單筒烘(hong)(hong)(hong)干(gan)(gan)機(ji)內(nei)部結構,增加入機(ji)前(qian)濕(shi)料的(de)(de)(de)預(yu)烘(hong)(hong)(hong)干(gan)(gan)和延長濕(shi)料在(zai)機(ji)內(nei)烘(hong)(hong)(hong)干(gan)(gan)時間,再加上密封、保溫以及合理的(de)(de)(de)配套措施(shi),使(shi)烘(hong)(hong)(hong)干(gan)(gan)機(ji)生產能力與原(yuan)單筒式(shi)(shi)烘(hong)(hong)(hong)干(gan)(gan)機(ji)相比,提高48-80%,單位容積蒸發強度(du)可達120-180kg/m3,標準煤(mei)(mei)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(yong)于各個行業的(de)(de)(de)礦渣(zha)、粘土、煤(mei)(mei)。
產品結構(gou)
三筒烘(hong)(hong)(hong)干(gan)(gan)(gan)機是通過對單(dan)筒烘(hong)(hong)(hong)干(gan)(gan)(gan)機的(de)單(dan)筒體(ti)改為套疊在(zai)一起的(de)三筒,以縮短烘(hong)(hong)(hong)干(gan)(gan)(gan)機體(ti)的(de)外(wai)形尺寸。該機工作時,物(wu)料和熱(re)氣流依次進入內至外(wai)筒體(ti),在(zai)機體(ti)Z形往復折(zhe)流后,充分(fen)利(li)用熱(re)能(neng)烘(hong)(hong)(hong)干(gan)(gan)(gan)物(wu)料后再卸出。
烘干機筒(tong)體(ti)(ti)部分由三(san)個(ge)同軸水(shui)平放置的(de)內、中、外筒(tong)套疊組成(cheng),這就使筒(tong)體(ti)(ti)的(de)截(jie)面(mian)得(de)到(dao)充分的(de)利用。其筒(tong)體(ti)(ti)外形總長度約為與之相當的(de)單筒(tong)的(de)30-35%。從而大(da)幅度地減(jian)少占地面(mian)積和廠房建筑面(mian)積。
該機的支承(cheng)裝置,是在外筒上輪帶與托輪支承(cheng),由電(dian)機直接(jie)帶動托輪。通(tong)過托輪與輪帶摩擦,使筒體轉(zhuan)動。該機總體結(jie)構緊湊、合(he)理、簡(jian)單,為(wei)便(bian)于磨(mo)損(sun)件的檢修(xiu)更(geng)換,在中(zhong)間設計成軸向剖分(fen)式,用(yong)螺栓固定連接(jie)。
