產品概況
回(hui)轉(zhuan)式(shi)(shi)三(san)筒烘(hong)干機(ji)(ji)改進原單(dan)筒烘(hong)干機(ji)(ji)內部(bu)結(jie)構,增加入(ru)機(ji)(ji)前濕料(liao)的預烘(hong)干和延(yan)長濕料(liao)在(zai)機(ji)(ji)內烘(hong)干時間,再加上密封、保溫以及合理的配套措施,使烘(hong)干機(ji)(ji)生產能力與原單(dan)筒式(shi)(shi)烘(hong)干機(ji)(ji)相比,提高48-80%,單(dan)位容積蒸(zheng)發強度可達120-180kg/m3,標準煤(mei)耗僅為6-8kg/t。其技術先進、運行(xing)參數合理,操作簡單(dan)可行(xing),廣泛應用于各個行(xing)業的礦渣、粘土、煤(mei)。
產品結構
三筒(tong)(tong)烘(hong)干(gan)(gan)機(ji)是通過對單(dan)(dan)筒(tong)(tong)烘(hong)干(gan)(gan)機(ji)的(de)單(dan)(dan)筒(tong)(tong)體(ti)改為套疊(die)在一起的(de)三筒(tong)(tong),以縮(suo)短烘(hong)干(gan)(gan)機(ji)體(ti)的(de)外形尺寸。該機(ji)工作時,物(wu)料(liao)和熱(re)氣(qi)流(liu)(liu)依次進(jin)入內至外筒(tong)(tong)體(ti),在機(ji)體(ti)Z形往復折流(liu)(liu)后,充分(fen)利用熱(re)能烘(hong)干(gan)(gan)物(wu)料(liao)后再卸出。
烘(hong)干機筒(tong)(tong)(tong)體(ti)部分由三個(ge)同軸(zhou)水平放置的(de)(de)內、中、外筒(tong)(tong)(tong)套疊組成,這就(jiu)使(shi)筒(tong)(tong)(tong)體(ti)的(de)(de)截面(mian)得(de)到(dao)充(chong)分的(de)(de)利用。其筒(tong)(tong)(tong)體(ti)外形總長度約為與之相當的(de)(de)單筒(tong)(tong)(tong)的(de)(de)30-35%。從(cong)而大幅度地減(jian)少占(zhan)地面(mian)積(ji)(ji)和廠房建(jian)筑面(mian)積(ji)(ji)。
該機的(de)支(zhi)承(cheng)(cheng)裝置,是在(zai)(zai)外筒上(shang)輪(lun)帶與托(tuo)輪(lun)支(zhi)承(cheng)(cheng),由電(dian)機直接帶動托(tuo)輪(lun)。通過托(tuo)輪(lun)與輪(lun)帶摩(mo)擦(ca),使筒體(ti)轉動。該機總體(ti)結構緊湊、合理、簡單,為(wei)便于磨損件的(de)檢(jian)修更換,在(zai)(zai)中間設計(ji)成軸向(xiang)剖分(fen)式,用(yong)螺(luo)栓固定連接。
工作原理
物(wu)(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝(zhuang)置進(jin)入(ru)回(hui)轉滾(gun)(gun)筒(tong)的(de)(de)內(nei)(nei)層(ceng)(ceng)(ceng),實現順流烘干(gan)(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)內(nei)(nei)層(ceng)(ceng)(ceng)的(de)(de)抄板下(xia)不(bu)斷抄起、散(san)落(luo)(luo)呈(cheng)螺旋行進(jin)式(shi)實現熱交換(huan),物(wu)(wu)(wu)(wu)料(liao)(liao)移動至內(nei)(nei)層(ceng)(ceng)(ceng)的(de)(de)另一端進(jin)入(ru)中層(ceng)(ceng)(ceng),進(jin)行逆(ni)流烘干(gan)(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)不(bu)斷地(di)被反復揚進(jin),呈(cheng)進(jin)兩(liang)步(bu)退一步(bu)的(de)(de)行進(jin)方(fang)式(shi),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)既充(chong)(chong)分(fen)吸收(shou)內(nei)(nei)層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)散(san)發的(de)(de)熱量(liang),又吸收(shou)中層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)的(de)(de)熱量(liang),同時(shi)又延(yan)長(chang)了干(gan)(gan)燥時(shi)間(jian),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此達到干(gan)(gan)燥狀態。物(wu)(wu)(wu)(wu)料(liao)(liao)行至中層(ceng)(ceng)(ceng)另一端而(er)落(luo)(luo)入(ru)外(wai)層(ceng)(ceng)(ceng),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)外(wai)層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)內(nei)(nei)呈(cheng)矩形多(duo)回(hui)路方(fang)式(shi)行進(jin),達到干(gan)(gan)燥效果的(de)(de)物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)熱風作(zuo)用(yong)下(xia)快速行進(jin)排(pai)出滾(gun)(gun)筒(tong),沒有達到干(gan)(gan)燥效果的(de)(de)濕物(wu)(wu)(wu)(wu)料(liao)(liao)因自重(zhong)而(er)不(bu)能快速行進(jin),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)此矩形抄板內(nei)(nei)進(jin)行充(chong)(chong)分(fen)干(gan)(gan)燥,由此完成干(gan)(gan)燥目(mu)的(de)(de)。
