產品(pin)概況
回轉式三筒(tong)烘(hong)(hong)(hong)干(gan)(gan)(gan)機(ji)改進(jin)原(yuan)單(dan)筒(tong)烘(hong)(hong)(hong)干(gan)(gan)(gan)機(ji)內部(bu)結構,增加入機(ji)前濕料(liao)的預烘(hong)(hong)(hong)干(gan)(gan)(gan)和延長濕料(liao)在機(ji)內烘(hong)(hong)(hong)干(gan)(gan)(gan)時(shi)間,再(zai)加上密封、保(bao)溫以及合理的配(pei)套措施,使(shi)烘(hong)(hong)(hong)干(gan)(gan)(gan)機(ji)生產能力與原(yuan)單(dan)筒(tong)式烘(hong)(hong)(hong)干(gan)(gan)(gan)機(ji)相(xiang)比,提高(gao)48-80%,單(dan)位容積蒸(zheng)發強度可(ke)達120-180kg/m3,標準(zhun)煤耗僅為6-8kg/t。其技術先進(jin)、運(yun)行參數合理,操作簡單(dan)可(ke)行,廣泛應用(yong)于各個行業(ye)的礦渣、粘土、煤。
產(chan)品結構
三筒(tong)烘干機是通(tong)過對單筒(tong)烘干機的單筒(tong)體改為套疊在一起的三筒(tong),以縮(suo)短烘干機體的外(wai)形尺寸(cun)。該機工(gong)作時,物料和熱(re)氣流依次進入內至外(wai)筒(tong)體,在機體Z形往復(fu)折流后(hou)(hou),充(chong)分(fen)利(li)用熱(re)能烘干物料后(hou)(hou)再卸出。
烘干機(ji)筒體(ti)部分由三個(ge)同軸水平放(fang)置的(de)(de)(de)內(nei)、中、外筒套疊組成,這就使(shi)筒體(ti)的(de)(de)(de)截面(mian)(mian)得到(dao)充分的(de)(de)(de)利用。其筒體(ti)外形總長度(du)約為與之(zhi)相當的(de)(de)(de)單(dan)筒的(de)(de)(de)30-35%。從而大幅度(du)地減(jian)少占地面(mian)(mian)積(ji)和廠房建(jian)筑面(mian)(mian)積(ji)。
該(gai)機的支(zhi)承裝置,是在外筒上(shang)輪(lun)(lun)帶與托(tuo)輪(lun)(lun)支(zhi)承,由電機直接帶動托(tuo)輪(lun)(lun)。通過托(tuo)輪(lun)(lun)與輪(lun)(lun)帶摩擦(ca),使筒體轉動。該(gai)機總體結(jie)構緊湊、合(he)理、簡單,為(wei)便于磨損(sun)件(jian)的檢(jian)修更(geng)換(huan),在中(zhong)間設(she)計成軸向剖分(fen)式(shi),用螺栓(shuan)固定連接。
工作原理
物(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝(zhuang)置進(jin)(jin)入回轉(zhuan)滾(gun)(gun)(gun)筒(tong)的(de)(de)內層(ceng)(ceng)(ceng)(ceng),實(shi)現順流烘干(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)內層(ceng)(ceng)(ceng)(ceng)的(de)(de)抄板(ban)下(xia)不斷抄起、散(san)落(luo)呈(cheng)螺旋行(xing)進(jin)(jin)式(shi)實(shi)現熱交(jiao)換,物(wu)(wu)(wu)料(liao)(liao)移(yi)動至內層(ceng)(ceng)(ceng)(ceng)的(de)(de)另(ling)一端進(jin)(jin)入中(zhong)層(ceng)(ceng)(ceng)(ceng),進(jin)(jin)行(xing)逆(ni)流烘干(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)不斷地被反復(fu)揚進(jin)(jin),呈(cheng)進(jin)(jin)兩步(bu)退一步(bu)的(de)(de)行(xing)進(jin)(jin)方(fang)式(shi),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)既充分吸收(shou)內層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)散(san)發(fa)的(de)(de)熱量,又(you)吸收(shou)中(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)的(de)(de)熱量,同時又(you)延長了(le)干(gan)燥(zao)(zao)時間,物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)此(ci)達(da)到(dao)干(gan)燥(zao)(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)行(xing)至中(zhong)層(ceng)(ceng)(ceng)(ceng)另(ling)一端而(er)落(luo)入外層(ceng)(ceng)(ceng)(ceng),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)內呈(cheng)矩(ju)形多回路方(fang)式(shi)行(xing)進(jin)(jin),達(da)到(dao)干(gan)燥(zao)(zao)效(xiao)果(guo)的(de)(de)物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)熱風作用下(xia)快速行(xing)進(jin)(jin)排出滾(gun)(gun)(gun)筒(tong),沒(mei)有(you)達(da)到(dao)干(gan)燥(zao)(zao)效(xiao)果(guo)的(de)(de)濕物(wu)(wu)(wu)料(liao)(liao)因自重(zhong)而(er)不能快速行(xing)進(jin)(jin),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)此(ci)矩(ju)形抄板(ban)內進(jin)(jin)行(xing)充分干(gan)燥(zao)(zao),由此(ci)完成(cheng)干(gan)燥(zao)(zao)目(mu)的(de)(de)。
