產品(pin)概況
回轉式三筒(tong)烘(hong)(hong)(hong)干(gan)機改(gai)進原(yuan)單筒(tong)烘(hong)(hong)(hong)干(gan)機內部(bu)結(jie)構,增加入機前濕(shi)料的(de)預烘(hong)(hong)(hong)干(gan)和延長濕(shi)料在機內烘(hong)(hong)(hong)干(gan)時間,再(zai)加上密封、保溫以及(ji)合(he)理的(de)配套(tao)措(cuo)施,使烘(hong)(hong)(hong)干(gan)機生產能力與原(yuan)單筒(tong)式烘(hong)(hong)(hong)干(gan)機相比,提高48-80%,單位容積蒸發強度可達120-180kg/m3,標準煤(mei)耗僅為6-8kg/t。其(qi)技(ji)術先進、運行參數合(he)理,操作(zuo)簡單可行,廣泛應用于各個行業的(de)礦渣、粘土、煤(mei)。
產品結構(gou)
三筒(tong)烘(hong)干(gan)機(ji)是通過對單(dan)筒(tong)烘(hong)干(gan)機(ji)的單(dan)筒(tong)體(ti)改為套疊(die)在一起(qi)的三筒(tong),以縮短烘(hong)干(gan)機(ji)體(ti)的外形(xing)尺寸。該機(ji)工作時(shi),物(wu)料和(he)熱(re)氣(qi)流依次進入(ru)內至外筒(tong)體(ti),在機(ji)體(ti)Z形(xing)往復折流后,充分利用熱(re)能(neng)烘(hong)干(gan)物(wu)料后再卸出。
烘干機筒(tong)(tong)體(ti)部分由三(san)個同軸水平放置的(de)內(nei)、中(zhong)、外(wai)(wai)筒(tong)(tong)套疊組成,這就使筒(tong)(tong)體(ti)的(de)截面得到充分的(de)利用。其筒(tong)(tong)體(ti)外(wai)(wai)形總長度(du)(du)約為與之(zhi)相(xiang)當的(de)單筒(tong)(tong)的(de)30-35%。從(cong)而大幅度(du)(du)地(di)減(jian)少占地(di)面積和廠房建筑面積。
該機的支(zhi)承裝(zhuang)置(zhi),是在(zai)外筒(tong)上(shang)輪(lun)(lun)帶(dai)(dai)與(yu)托輪(lun)(lun)支(zhi)承,由(you)電機直接(jie)帶(dai)(dai)動(dong)托輪(lun)(lun)。通(tong)過托輪(lun)(lun)與(yu)輪(lun)(lun)帶(dai)(dai)摩(mo)擦(ca),使筒(tong)體(ti)轉動(dong)。該機總體(ti)結(jie)構緊湊(cou)、合理、簡單(dan),為便(bian)于磨損件(jian)的檢修更換,在(zai)中(zhong)間設計成軸(zhou)向(xiang)剖分式,用螺栓固定(ding)連接(jie)。
工作原理
物(wu)(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝(zhuang)置進(jin)(jin)(jin)入回轉滾筒的(de)內(nei)(nei)層(ceng),實現順流烘干(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)內(nei)(nei)層(ceng)的(de)抄板下不斷(duan)抄起、散落呈(cheng)(cheng)螺旋行(xing)(xing)(xing)(xing)進(jin)(jin)(jin)式(shi)實現熱交換(huan),物(wu)(wu)(wu)(wu)料(liao)(liao)移動至(zhi)(zhi)內(nei)(nei)層(ceng)的(de)另一端進(jin)(jin)(jin)入中層(ceng),進(jin)(jin)(jin)行(xing)(xing)(xing)(xing)逆流烘干(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)中層(ceng)不斷(duan)地(di)被反復揚進(jin)(jin)(jin),呈(cheng)(cheng)進(jin)(jin)(jin)兩步(bu)退一步(bu)的(de)行(xing)(xing)(xing)(xing)進(jin)(jin)(jin)方式(shi),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)中層(ceng)既充(chong)分吸(xi)收(shou)內(nei)(nei)層(ceng)滾筒散發(fa)的(de)熱量(liang)(liang),又吸(xi)收(shou)中層(ceng)滾筒的(de)熱量(liang)(liang),同時又延長了干(gan)燥(zao)(zao)(zao)時間,物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)此(ci)達到(dao)干(gan)燥(zao)(zao)(zao)狀態。物(wu)(wu)(wu)(wu)料(liao)(liao)行(xing)(xing)(xing)(xing)至(zhi)(zhi)中層(ceng)另一端而(er)落入外層(ceng),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)外層(ceng)滾筒內(nei)(nei)呈(cheng)(cheng)矩形多回路方式(shi)行(xing)(xing)(xing)(xing)進(jin)(jin)(jin),達到(dao)干(gan)燥(zao)(zao)(zao)效果的(de)物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)熱風作用下快速行(xing)(xing)(xing)(xing)進(jin)(jin)(jin)排(pai)出(chu)滾筒,沒有達到(dao)干(gan)燥(zao)(zao)(zao)效果的(de)濕(shi)物(wu)(wu)(wu)(wu)料(liao)(liao)因(yin)自重而(er)不能快速行(xing)(xing)(xing)(xing)進(jin)(jin)(jin),物(wu)(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)此(ci)矩形抄板內(nei)(nei)進(jin)(jin)(jin)行(xing)(xing)(xing)(xing)充(chong)分干(gan)燥(zao)(zao)(zao),由此(ci)完成(cheng)干(gan)燥(zao)(zao)(zao)目的(de)。
