產品概況
回轉(zhuan)式(shi)三筒(tong)烘(hong)干(gan)(gan)機改(gai)進原(yuan)單筒(tong)烘(hong)干(gan)(gan)機內部(bu)結構,增(zeng)加入機前濕料的(de)(de)預烘(hong)干(gan)(gan)和延長濕料在機內烘(hong)干(gan)(gan)時(shi)間,再加上密封、保溫(wen)以及(ji)合理的(de)(de)配(pei)套措(cuo)施,使烘(hong)干(gan)(gan)機生(sheng)產能力與原(yuan)單筒(tong)式(shi)烘(hong)干(gan)(gan)機相比(bi),提高48-80%,單位容(rong)積(ji)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(guang)泛應用于各個行業的(de)(de)礦渣、粘(zhan)土、煤。
產品結構(gou)
三筒烘干(gan)機是(shi)通過對單筒烘干(gan)機的單筒體(ti)改為套疊在一(yi)起的三筒,以縮短烘干(gan)機體(ti)的外形尺寸(cun)。該機工(gong)作時,物(wu)料和熱氣流(liu)依次進入(ru)內至外筒體(ti),在機體(ti)Z形往復折流(liu)后(hou),充分利用熱能烘干(gan)物(wu)料后(hou)再卸出。
烘(hong)干機筒(tong)體(ti)部分由三個同軸水(shui)平放置的(de)(de)內、中、外筒(tong)套疊組成,這就使筒(tong)體(ti)的(de)(de)截面得到(dao)充分的(de)(de)利用。其筒(tong)體(ti)外形總長度(du)(du)約為(wei)與(yu)之相當的(de)(de)單筒(tong)的(de)(de)30-35%。從而大(da)幅度(du)(du)地(di)減少占地(di)面積(ji)和(he)廠房(fang)建筑面積(ji)。
該(gai)機的支承裝置,是在外筒上輪帶(dai)與(yu)托(tuo)輪支承,由電機直接(jie)帶(dai)動托(tuo)輪。通(tong)過托(tuo)輪與(yu)輪帶(dai)摩擦,使筒體(ti)轉動。該(gai)機總(zong)體(ti)結構(gou)緊湊、合理、簡(jian)單,為便于(yu)磨損件的檢修更換,在中間(jian)設計成軸(zhou)向剖分式,用螺栓固定連(lian)接(jie)。
