產品概況
回轉式(shi)三(san)筒烘(hong)干機(ji)(ji)改進原(yuan)單(dan)筒烘(hong)干機(ji)(ji)內(nei)部結(jie)構,增加入機(ji)(ji)前(qian)濕料的(de)預(yu)烘(hong)干和延(yan)長濕料在機(ji)(ji)內(nei)烘(hong)干時間(jian),再加上密封、保(bao)溫以及合理的(de)配套(tao)措施,使烘(hong)干機(ji)(ji)生產能(neng)力與原(yuan)單(dan)筒式(shi)烘(hong)干機(ji)(ji)相比,提高48-80%,單(dan)位容積蒸發強度可(ke)達(da)120-180kg/m3,標準煤耗僅為6-8kg/t。其(qi)技術(shu)先進、運行參數合理,操作(zuo)簡單(dan)可(ke)行,廣泛應用于(yu)各(ge)個行業(ye)的(de)礦渣、粘土、煤。
產品結(jie)構
三(san)筒(tong)(tong)烘(hong)干(gan)機(ji)是通(tong)過對單(dan)(dan)筒(tong)(tong)烘(hong)干(gan)機(ji)的(de)單(dan)(dan)筒(tong)(tong)體(ti)改(gai)為套疊(die)在一(yi)起的(de)三(san)筒(tong)(tong),以縮短烘(hong)干(gan)機(ji)體(ti)的(de)外(wai)形(xing)尺寸。該機(ji)工作時,物料和熱氣流(liu)依次進入內至外(wai)筒(tong)(tong)體(ti),在機(ji)體(ti)Z形(xing)往(wang)復折流(liu)后,充分利(li)用熱能(neng)烘(hong)干(gan)物料后再卸(xie)出。
烘干機筒(tong)體(ti)部分(fen)由(you)三(san)個同軸水平放置的內、中、外筒(tong)套疊組(zu)成,這(zhe)就使(shi)筒(tong)體(ti)的截面(mian)得到充分(fen)的利用。其筒(tong)體(ti)外形總長度(du)(du)約為與之相(xiang)當(dang)的單筒(tong)的30-35%。從而大幅度(du)(du)地減少占地面(mian)積和廠(chang)房建筑面(mian)積。
該機(ji)的支承(cheng)裝(zhuang)置,是在外筒上輪(lun)(lun)帶與(yu)托(tuo)輪(lun)(lun)支承(cheng),由電機(ji)直接帶動托(tuo)輪(lun)(lun)。通過托(tuo)輪(lun)(lun)與(yu)輪(lun)(lun)帶摩(mo)擦(ca),使(shi)筒體轉(zhuan)動。該機(ji)總體結構緊湊、合理、簡單,為(wei)便于磨(mo)損件的檢修更換,在中間設計成(cheng)軸(zhou)向剖分(fen)式,用(yong)螺栓固定連接。
工作原理
物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)由(you)供料(liao)(liao)(liao)裝置進(jin)入回轉滾(gun)筒(tong)(tong)的(de)(de)內(nei)層(ceng),實現順流烘(hong)干(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)內(nei)層(ceng)的(de)(de)抄板(ban)下不斷(duan)抄起、散落呈(cheng)螺(luo)旋行進(jin)式實現熱(re)(re)交(jiao)換,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)移動至內(nei)層(ceng)的(de)(de)另一端(duan)進(jin)入中層(ceng),進(jin)行逆流烘(hong)干(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)中層(ceng)不斷(duan)地被反復揚進(jin),呈(cheng)進(jin)兩步退一步的(de)(de)行進(jin)方(fang)式,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)中層(ceng)既(ji)充(chong)分(fen)吸收(shou)內(nei)層(ceng)滾(gun)筒(tong)(tong)散發的(de)(de)熱(re)(re)量,又吸收(shou)中層(ceng)滾(gun)筒(tong)(tong)的(de)(de)熱(re)(re)量,同(tong)時又延長了(le)干(gan)燥(zao)(zao)(zao)時間,物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)此(ci)達(da)(da)到(dao)(dao)干(gan)燥(zao)(zao)(zao)狀態。物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)行至中層(ceng)另一端(duan)而(er)落入外層(ceng),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)外層(ceng)滾(gun)筒(tong)(tong)內(nei)呈(cheng)矩形多回路方(fang)式行進(jin),達(da)(da)到(dao)(dao)干(gan)燥(zao)(zao)(zao)效(xiao)果的(de)(de)物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)熱(re)(re)風作用(yong)下快速行進(jin)排出滾(gun)筒(tong)(tong),沒(mei)有達(da)(da)到(dao)(dao)干(gan)燥(zao)(zao)(zao)效(xiao)果的(de)(de)濕物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)因自(zi)重而(er)不能快速行進(jin),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)此(ci)矩形抄板(ban)內(nei)進(jin)行充(chong)分(fen)干(gan)燥(zao)(zao)(zao),由(you)此(ci)完成干(gan)燥(zao)(zao)(zao)目的(de)(de)。
