產(chan)品(pin)概況
回轉(zhuan)式三筒(tong)烘(hong)干(gan)機(ji)(ji)(ji)改進原(yuan)(yuan)單筒(tong)烘(hong)干(gan)機(ji)(ji)(ji)內部結(jie)構,增加入(ru)機(ji)(ji)(ji)前濕(shi)料的預烘(hong)干(gan)和延長濕(shi)料在機(ji)(ji)(ji)內烘(hong)干(gan)時間,再加上密封、保溫以及合理(li)的配套(tao)措施,使(shi)烘(hong)干(gan)機(ji)(ji)(ji)生產能力與原(yuan)(yuan)單筒(tong)式烘(hong)干(gan)機(ji)(ji)(ji)相比,提高48-80%,單位容積(ji)蒸(zheng)發(fa)強度可達120-180kg/m3,標(biao)準煤耗(hao)僅為6-8kg/t。其技(ji)術先進、運(yun)行(xing)(xing)參數合理(li),操(cao)作(zuo)簡單可行(xing)(xing),廣泛應用(yong)于(yu)各(ge)個行(xing)(xing)業的礦渣、粘土、煤。
產品(pin)結構
三筒烘(hong)干(gan)(gan)機(ji)是通過對單(dan)筒烘(hong)干(gan)(gan)機(ji)的(de)單(dan)筒體(ti)改(gai)為套疊在(zai)(zai)一起的(de)三筒,以縮短烘(hong)干(gan)(gan)機(ji)體(ti)的(de)外形尺寸。該(gai)機(ji)工作時,物(wu)料和(he)熱(re)氣(qi)流依次進入內至外筒體(ti),在(zai)(zai)機(ji)體(ti)Z形往(wang)復折流后(hou),充分利(li)用熱(re)能烘(hong)干(gan)(gan)物(wu)料后(hou)再卸出。
烘干機筒(tong)體部分(fen)由(you)三個同軸水(shui)平(ping)放(fang)置的內(nei)、中、外筒(tong)套疊組(zu)成,這就使筒(tong)體的截面得到充分(fen)的利用(yong)。其筒(tong)體外形(xing)總長(chang)度(du)約為與之相當的單(dan)筒(tong)的30-35%。從而大幅度(du)地(di)(di)減少占地(di)(di)面積和廠(chang)房(fang)建筑面積。
該(gai)機(ji)的支承(cheng)裝置,是(shi)在外筒(tong)(tong)上輪(lun)帶與托(tuo)(tuo)輪(lun)支承(cheng),由電機(ji)直接帶動托(tuo)(tuo)輪(lun)。通過托(tuo)(tuo)輪(lun)與輪(lun)帶摩擦,使筒(tong)(tong)體(ti)(ti)轉動。該(gai)機(ji)總體(ti)(ti)結構緊湊、合理、簡單(dan),為便于磨損件的檢修(xiu)更換,在中(zhong)間設計成軸向(xiang)剖分式,用螺栓固定連接。
工(gong)作原理
物(wu)(wu)料(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)裝置進(jin)入(ru)回(hui)轉滾(gun)(gun)筒(tong)(tong)的內(nei)(nei)層(ceng)(ceng)(ceng),實現(xian)順流烘(hong)干(gan)(gan),物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)內(nei)(nei)層(ceng)(ceng)(ceng)的抄板下(xia)不(bu)斷(duan)抄起、散落(luo)呈(cheng)螺旋行(xing)(xing)進(jin)式實現(xian)熱(re)(re)交換,物(wu)(wu)料(liao)(liao)(liao)(liao)移動至內(nei)(nei)層(ceng)(ceng)(ceng)的另一(yi)端(duan)進(jin)入(ru)中(zhong)層(ceng)(ceng)(ceng),進(jin)行(xing)(xing)逆流烘(hong)干(gan)(gan),物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)不(bu)斷(duan)地被反復(fu)揚進(jin),呈(cheng)進(jin)兩步退一(yi)步的行(xing)(xing)進(jin)方式,物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)中(zhong)層(ceng)(ceng)(ceng)既充分吸收內(nei)(nei)層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)散發的熱(re)(re)量(liang),又吸收中(zhong)層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)的熱(re)(re)量(liang),同時(shi)(shi)又延長(chang)了干(gan)(gan)燥時(shi)(shi)間,物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)此(ci)達到干(gan)(gan)燥狀態(tai)。物(wu)(wu)料(liao)(liao)(liao)(liao)行(xing)(xing)至中(zhong)層(ceng)(ceng)(ceng)另一(yi)端(duan)而落(luo)入(ru)外(wai)(wai)層(ceng)(ceng)(ceng),物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)外(wai)(wai)層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)內(nei)(nei)呈(cheng)矩形多(duo)回(hui)路方式行(xing)(xing)進(jin),達到干(gan)(gan)燥效果的物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)熱(re)(re)風作用(yong)下(xia)快(kuai)速(su)行(xing)(xing)進(jin)排出滾(gun)(gun)筒(tong)(tong),沒有達到干(gan)(gan)燥效果的濕物(wu)(wu)料(liao)(liao)(liao)(liao)因自重而不(bu)能快(kuai)速(su)行(xing)(xing)進(jin),物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)此(ci)矩形抄板內(nei)(nei)進(jin)行(xing)(xing)充分干(gan)(gan)燥,由此(ci)完成干(gan)(gan)燥目的。
