產品概況
回轉式三筒烘干(gan)機(ji)改進(jin)原單(dan)筒烘干(gan)機(ji)內部結構,增加入機(ji)前濕(shi)(shi)料的(de)預(yu)烘干(gan)和延長濕(shi)(shi)料在機(ji)內烘干(gan)時間,再加上密封(feng)、保(bao)溫以(yi)及合(he)理的(de)配套措施,使烘干(gan)機(ji)生產能力與(yu)原單(dan)筒式烘干(gan)機(ji)相比,提高48-80%,單(dan)位容積蒸發強(qiang)度可(ke)達120-180kg/m3,標準煤耗(hao)僅(jin)為6-8kg/t。其技術先進(jin)、運行參數合(he)理,操作簡單(dan)可(ke)行,廣泛應用于(yu)各(ge)個行業的(de)礦渣、粘土、煤。
產品結構
三筒烘干機是(shi)通過對(dui)單筒烘干機的單筒體(ti)(ti)改為(wei)套(tao)疊在一起(qi)的三筒,以縮短(duan)烘干機體(ti)(ti)的外形尺寸。該機工作(zuo)時,物(wu)料和(he)熱氣(qi)流依次進入內至外筒體(ti)(ti),在機體(ti)(ti)Z形往復折流后(hou),充(chong)分利用熱能烘干物(wu)料后(hou)再卸出。
烘干(gan)機筒(tong)體(ti)(ti)部分(fen)由(you)三個同軸水平放置的(de)內、中(zhong)、外筒(tong)套疊組(zu)成,這就使筒(tong)體(ti)(ti)的(de)截(jie)面(mian)得(de)到充分(fen)的(de)利用。其筒(tong)體(ti)(ti)外形總(zong)長(chang)度(du)約為與(yu)之相當的(de)單筒(tong)的(de)30-35%。從而大幅度(du)地減少占地面(mian)積和(he)廠(chang)房建筑面(mian)積。
該機的支(zhi)承裝置,是在(zai)外筒上輪帶與托輪支(zhi)承,由電機直接(jie)帶動托輪。通過托輪與輪帶摩(mo)擦,使筒體(ti)轉動。該機總體(ti)結構(gou)緊湊、合理、簡單(dan),為便(bian)于(yu)磨損件的檢(jian)修更換(huan),在(zai)中間(jian)設(she)計成(cheng)軸(zhou)向剖分(fen)式,用(yong)螺栓固定連(lian)接(jie)。
