產品概況(kuang)
回轉式三筒烘干機改進原單筒烘干機內部結構，增加入機前濕料的預烘干和延長濕料在機內烘干時間，再加上密封、保溫以及合理的配套措施，使烘干機生產能力與原單筒式烘干機相比，提高48-80%，單位容積蒸發強度可達120-180kg/m3，標準煤耗僅為6-8kg/t。其技術先進、運行參數合理，操作簡單可行，廣泛應用于各個行業的礦渣、粘土、煤。
產(chan)品(pin)結(jie)構
三筒(tong)(tong)(tong)式(shi)烘干(gan)機(ji)(ji)(ji)是通過對單筒(tong)(tong)(tong)烘干(gan)機(ji)(ji)(ji)的單筒(tong)(tong)(tong)體改(gai)為套疊在一起的三筒(tong)(tong)(tong)，以(yi)縮短烘干(gan)機(ji)(ji)(ji)體的外形尺寸。該機(ji)(ji)(ji)工(gong)作時(shi)，物料和熱氣流依(yi)次進入(ru)內至外筒(tong)(tong)(tong)體，在機(ji)(ji)(ji)體Z形往復折(zhe)流后(hou)(hou)，充分利用熱能烘干(gan)物料后(hou)(hou)再卸出。
烘干機筒(tong)(tong)(tong)體(ti)(ti)部(bu)分(fen)由三(san)個同(tong)軸水平放置的(de)內、中、外筒(tong)(tong)(tong)套疊組成，這就(jiu)使筒(tong)(tong)(tong)體(ti)(ti)的(de)截面得到充分(fen)的(de)利用。其筒(tong)(tong)(tong)體(ti)(ti)外形(xing)總長(chang)度(du)約為與(yu)之相當的(de)單筒(tong)(tong)(tong)的(de)30-35%。從(cong)而(er)大幅(fu)度(du)地(di)減少占地(di)面積和廠房建筑面積。
該機的(de)支承裝置，是(shi)在外筒(tong)上輪(lun)帶與托輪(lun)支承，由電機直接(jie)帶動托輪(lun)。通過(guo)托輪(lun)與輪(lun)帶摩擦，使筒(tong)體(ti)轉動。該機總體(ti)結(jie)構緊湊、合理、簡(jian)單，為便于(yu)磨損(sun)件的(de)檢修更(geng)換，在中間設計成軸向剖分式(shi)，用螺栓固(gu)定連接(jie)。
工作原理
物(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置進(jin)(jin)(jin)(jin)入(ru)回(hui)轉滾(gun)(gun)筒(tong)的內(nei)層(ceng)(ceng),實現順流(liu)烘(hong)干(gan)(gan)(gan)(gan)(gan),物(wu)(wu)料(liao)(liao)在(zai)(zai)內(nei)層(ceng)(ceng)的抄板下不斷(duan)抄起、散(san)落呈(cheng)螺旋行(xing)進(jin)(jin)(jin)(jin)式(shi)實現熱(re)交換，物(wu)(wu)料(liao)(liao)移動(dong)至內(nei)層(ceng)(ceng)的另一(yi)端進(jin)(jin)(jin)(jin)入(ru)中(zhong)層(ceng)(ceng)，進(jin)(jin)(jin)(jin)行(xing)逆流(liu)烘(hong)干(gan)(gan)(gan)(gan)(gan)，物(wu)(wu)料(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)不斷(duan)地(di)被反復揚進(jin)(jin)(jin)(jin)，呈(cheng)進(jin)(jin)(jin)(jin)兩步退一(yi)步的行(xing)進(jin)(jin)(jin)(jin)方式(shi)，物(wu)(wu)料(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)既充分吸收(shou)內(nei)層(ceng)(ceng)滾(gun)(gun)筒(tong)散(san)發的熱(re)量(liang)(liang)，又(you)吸收(shou)中(zhong)層(ceng)(ceng)滾(gun)(gun)筒(tong)的熱(re)量(liang)(liang)，同時又(you)延長了干(gan)(gan)(gan)(gan)(gan)燥(zao)時間，物(wu)(wu)料(liao)(liao)在(zai)(zai)此(ci)達到干(gan)(gan)(gan)(gan)(gan)燥(zao)狀(zhuang)態。物(wu)(wu)料(liao)(liao)行(xing)至中(zhong)層(ceng)(ceng)另一(yi)端而(er)落入(ru)外層(ceng)(ceng)，物(wu)(wu)料(liao)(liao)在(zai)(zai)外層(ceng)(ceng)滾(gun)(gun)筒(tong)內(nei)呈(cheng)矩形多回(hui)路(lu)方式(shi)行(xing)進(jin)(jin)(jin)(jin)，達到干(gan)(gan)(gan)(gan)(gan)燥(zao)效(xiao)果的物(wu)(wu)料(liao)(liao)在(zai)(zai)熱(re)風作用下快速行(xing)進(jin)(jin)(jin)(jin)排出滾(gun)(gun)筒(tong)，沒有(you)達到干(gan)(gan)(gan)(gan)(gan)燥(zao)效(xiao)果的濕物(wu)(wu)料(liao)(liao)因自重而(er)不能快速行(xing)進(jin)(jin)(jin)(jin)，物(wu)(wu)料(liao)(liao)在(zai)(zai)此(ci)矩形抄板內(nei)進(jin)(jin)(jin)(jin)行(xing)充分干(gan)(gan)(gan)(gan)(gan)燥(zao)，由此(ci)完(wan)成干(gan)(gan)(gan)(gan)(gan)燥(zao)目的。
