產(chan)品概(gai)況
回轉式(shi)(shi)三筒烘(hong)干(gan)機(ji)(ji)(ji)改進原單筒烘(hong)干(gan)機(ji)(ji)(ji)內(nei)(nei)部結構，增加入機(ji)(ji)(ji)前(qian)濕料的預烘(hong)干(gan)和延長濕料在(zai)機(ji)(ji)(ji)內(nei)(nei)烘(hong)干(gan)時(shi)間，再加上密封(feng)、保溫(wen)以及合理的配套措施，使(shi)烘(hong)干(gan)機(ji)(ji)(ji)生產(chan)能力與原單筒式(shi)(shi)烘(hong)干(gan)機(ji)(ji)(ji)相比，提高(gao)48-80%，單位容積蒸發(fa)強度(du)可達(da)120-180kg/m3，標準煤(mei)(mei)耗(hao)僅為6-8kg/t。其技術先進、運行(xing)(xing)參數合理，操作簡單可行(xing)(xing)，廣泛應用于(yu)各個行(xing)(xing)業的礦(kuang)渣(zha)、粘(zhan)土、煤(mei)(mei)。
產品(pin)結構
三筒烘干(gan)機(ji)是通(tong)過對(dui)單筒烘干(gan)機(ji)的單筒體(ti)(ti)改為套(tao)疊在一起的三筒，以縮短(duan)烘干(gan)機(ji)體(ti)(ti)的外形(xing)尺寸(cun)。該機(ji)工作時，物料(liao)和熱氣流依次(ci)進(jin)入(ru)內至外筒體(ti)(ti)，在機(ji)體(ti)(ti)Z形(xing)往(wang)復折流后(hou)，充分利用熱能(neng)烘干(gan)物料(liao)后(hou)再卸出(chu)。
烘干機筒(tong)(tong)體(ti)部分(fen)由三個同(tong)軸(zhou)水平放置(zhi)的內、中、外筒(tong)(tong)套疊(die)組(zu)成，這(zhe)就(jiu)使筒(tong)(tong)體(ti)的截面得到充分(fen)的利用(yong)。其(qi)筒(tong)(tong)體(ti)外形總長度(du)約為(wei)與之相當的單筒(tong)(tong)的30-35%。從而大幅度(du)地(di)減少占地(di)面積和(he)廠房(fang)建(jian)筑(zhu)面積。
該機的(de)支(zhi)承裝置(zhi)，是(shi)在外筒上輪(lun)帶(dai)與托輪(lun)支(zhi)承，由(you)電機直接(jie)(jie)帶(dai)動(dong)(dong)托輪(lun)。通過托輪(lun)與輪(lun)帶(dai)摩(mo)擦，使(shi)筒體(ti)轉動(dong)(dong)。該機總體(ti)結構緊湊、合理、簡單(dan)，為便于磨損件的(de)檢修更(geng)換，在中間設(she)計(ji)成軸向剖分式，用螺(luo)栓固定連接(jie)(jie)。
工作(zuo)原(yuan)理
物(wu)(wu)(wu)(wu)料(liao)由供料(liao)裝(zhuang)置進(jin)入回轉滾(gun)(gun)筒(tong)的(de)(de)(de)內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng),實現順流烘(hong)干(gan),物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)(zai)內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)抄板下(xia)不斷(duan)抄起(qi)、散落(luo)呈(cheng)螺旋行(xing)(xing)(xing)進(jin)式(shi)實現熱(re)(re)(re)交換(huan)，物(wu)(wu)(wu)(wu)料(liao)移動至(zhi)內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)另一端(duan)進(jin)入中層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)，進(jin)行(xing)(xing)(xing)逆流烘(hong)干(gan)，物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)(zai)中層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)不斷(duan)地被反復(fu)揚進(jin)，呈(cheng)進(jin)兩步退一步的(de)(de)(de)行(xing)(xing)(xing)進(jin)方式(shi)，物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)(zai)中層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)既充(chong)分(fen)吸收內(nei)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)散發的(de)(de)(de)熱(re)(re)(re)量(liang)，又(you)吸收中層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)的(de)(de)(de)熱(re)(re)(re)量(liang)，同時又(you)延長了干(gan)燥時間，物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)(zai)此(ci)達到干(gan)燥狀態。物(wu)(wu)(wu)(wu)料(liao)行(xing)(xing)(xing)至(zhi)中層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)另一端(duan)而落(luo)入外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)，物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)(zai)外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)內(nei)呈(cheng)矩(ju)形(xing)(xing)多回路(lu)方式(shi)行(xing)(xing)(xing)進(jin)，達到干(gan)燥效果的(de)(de)(de)物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)(zai)熱(re)(re)(re)風作用下(xia)快(kuai)速行(xing)(xing)(xing)進(jin)排(pai)出滾(gun)(gun)筒(tong)，沒有達到干(gan)燥效果的(de)(de)(de)濕物(wu)(wu)(wu)(wu)料(liao)因自重而不能(neng)快(kuai)速行(xing)(xing)(xing)進(jin)，物(wu)(wu)(wu)(wu)料(liao)在(zai)(zai)(zai)此(ci)矩(ju)形(xing)(xing)抄板內(nei)進(jin)行(xing)(xing)(xing)充(chong)分(fen)干(gan)燥，由此(ci)完成干(gan)燥目的(de)(de)(de)。
