產品(pin)概況
回轉式三筒烘(hong)(hong)干(gan)(gan)(gan)機(ji)(ji)改進(jin)原單(dan)筒烘(hong)(hong)干(gan)(gan)(gan)機(ji)(ji)內部結構(gou)，增加入機(ji)(ji)前濕料(liao)的預烘(hong)(hong)干(gan)(gan)(gan)和延(yan)長濕料(liao)在機(ji)(ji)內烘(hong)(hong)干(gan)(gan)(gan)時間，再加上密(mi)封、保溫以及合理的配套措(cuo)施，使烘(hong)(hong)干(gan)(gan)(gan)機(ji)(ji)生產能(neng)力與原單(dan)筒式烘(hong)(hong)干(gan)(gan)(gan)機(ji)(ji)相比，提高48-80%，單(dan)位容積蒸發強度可(ke)達120-180kg/m3，標準煤耗僅為6-8kg/t。其技術先進(jin)、運(yun)行(xing)(xing)(xing)參(can)數合理，操作簡單(dan)可(ke)行(xing)(xing)(xing)，廣泛應用(yong)于各個行(xing)(xing)(xing)業的礦(kuang)渣、粘土、煤。
產(chan)品(pin)結構
三筒(tong)烘干(gan)(gan)機(ji)(ji)是(shi)通過對單筒(tong)烘干(gan)(gan)機(ji)(ji)的單筒(tong)體改為(wei)套疊在(zai)一起(qi)的三筒(tong)，以縮短烘干(gan)(gan)機(ji)(ji)體的外形尺寸。該機(ji)(ji)工作時(shi)，物料和熱(re)氣流(liu)依次進入內至外筒(tong)體，在(zai)機(ji)(ji)體Z形往(wang)復折流(liu)后(hou)，充分利用熱(re)能(neng)烘干(gan)(gan)物料后(hou)再卸(xie)出。
烘干(gan)機(ji)筒(tong)(tong)(tong)體部分由三個同軸水平放置(zhi)的(de)(de)內、中(zhong)、外筒(tong)(tong)(tong)套疊(die)組成(cheng)，這就使筒(tong)(tong)(tong)體的(de)(de)截面(mian)得到充分的(de)(de)利(li)用。其筒(tong)(tong)(tong)體外形總長度(du)約為與(yu)之相(xiang)當的(de)(de)單筒(tong)(tong)(tong)的(de)(de)30-35%。從而(er)大幅度(du)地減少(shao)占地面(mian)積和廠房(fang)建筑面(mian)積。
該機(ji)的(de)支承裝置，是在(zai)外筒(tong)上輪(lun)(lun)(lun)帶(dai)(dai)與(yu)托輪(lun)(lun)(lun)支承，由(you)電機(ji)直接(jie)(jie)帶(dai)(dai)動托輪(lun)(lun)(lun)。通過(guo)托輪(lun)(lun)(lun)與(yu)輪(lun)(lun)(lun)帶(dai)(dai)摩(mo)擦，使筒(tong)體轉(zhuan)動。該機(ji)總體結構緊湊、合理、簡單，為便于磨損件的(de)檢(jian)修更換，在(zai)中間設計成軸向剖(pou)分式，用螺栓固(gu)定連(lian)接(jie)(jie)。
工作原理
物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)(liao)裝置進(jin)(jin)入回轉滾(gun)筒(tong)(tong)的內(nei)層(ceng)(ceng),實現順流烘干(gan),物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)內(nei)層(ceng)(ceng)的抄板下不斷(duan)抄起(qi)、散落呈螺旋行(xing)(xing)(xing)進(jin)(jin)式實現熱(re)(re)交換，物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)移(yi)動至內(nei)層(ceng)(ceng)的另一(yi)端進(jin)(jin)入中(zhong)層(ceng)(ceng)，進(jin)(jin)行(xing)(xing)(xing)逆流烘干(gan)，物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)不斷(duan)地(di)被(bei)反復揚進(jin)(jin)，呈進(jin)(jin)兩(liang)步退一(yi)步的行(xing)(xing)(xing)進(jin)(jin)方(fang)式，物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)既(ji)充分吸收內(nei)層(ceng)(ceng)滾(gun)筒(tong)(tong)散發的熱(re)(re)量，又(you)吸收中(zhong)層(ceng)(ceng)滾(gun)筒(tong)(tong)的熱(re)(re)量，同時(shi)又(you)延長了(le)干(gan)燥時(shi)間(jian)，物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)此(ci)(ci)達(da)到干(gan)燥狀態(tai)。物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)行(xing)(xing)(xing)至中(zhong)層(ceng)(ceng)另一(yi)端而(er)(er)落入外(wai)層(ceng)(ceng)，物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)外(wai)層(ceng)(ceng)滾(gun)筒(tong)(tong)內(nei)呈矩(ju)(ju)形(xing)多回路(lu)方(fang)式行(xing)(xing)(xing)進(jin)(jin)，達(da)到干(gan)燥效(xiao)果(guo)的物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)熱(re)(re)風作用下快速(su)行(xing)(xing)(xing)進(jin)(jin)排(pai)出滾(gun)筒(tong)(tong)，沒有達(da)到干(gan)燥效(xiao)果(guo)的濕物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)因自重而(er)(er)不能快速(su)行(xing)(xing)(xing)進(jin)(jin)，物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)在(zai)(zai)此(ci)(ci)矩(ju)(ju)形(xing)抄板內(nei)進(jin)(jin)行(xing)(xing)(xing)充分干(gan)燥，由此(ci)(ci)完成干(gan)燥目(mu)的。
