產品概況
回轉式三筒(tong)(tong)烘(hong)(hong)干機(ji)(ji)改進原(yuan)單筒(tong)(tong)烘(hong)(hong)干機(ji)(ji)內(nei)部結構(gou)，增加入機(ji)(ji)前濕料(liao)的預烘(hong)(hong)干和延長濕料(liao)在(zai)機(ji)(ji)內(nei)烘(hong)(hong)干時(shi)間，再加上密封、保溫以及合理的配套措(cuo)施，使烘(hong)(hong)干機(ji)(ji)生產(chan)能(neng)力與原(yuan)單筒(tong)(tong)式烘(hong)(hong)干機(ji)(ji)相(xiang)比(bi)，提(ti)高48-80%，單位容積蒸發強度(du)可達(da)120-180kg/m3，標(biao)準煤耗僅為(wei)6-8kg/t。其技(ji)術先進、運(yun)行(xing)參數(shu)合理，操作簡單可行(xing)，廣泛應(ying)用于各個(ge)行(xing)業(ye)的礦(kuang)渣、粘土、煤。
產品結構
三筒(tong)(tong)(tong)烘干機(ji)是(shi)通過對單筒(tong)(tong)(tong)烘干機(ji)的單筒(tong)(tong)(tong)體(ti)改為套(tao)疊在一起的三筒(tong)(tong)(tong)，以縮短烘干機(ji)體(ti)的外(wai)形尺(chi)寸。該(gai)機(ji)工作(zuo)時(shi)，物(wu)料和熱氣(qi)流(liu)依次(ci)進(jin)入內至外(wai)筒(tong)(tong)(tong)體(ti)，在機(ji)體(ti)Z形往復折流(liu)后，充(chong)分(fen)利用(yong)熱能烘干物(wu)料后再卸出。
烘(hong)干機(ji)筒(tong)(tong)(tong)體部(bu)分由(you)三個同軸(zhou)水平(ping)放置的內、中、外(wai)筒(tong)(tong)(tong)套疊組成，這就使筒(tong)(tong)(tong)體的截面(mian)得到充分的利(li)用(yong)。其(qi)筒(tong)(tong)(tong)體外(wai)形總(zong)長度約(yue)為與之相(xiang)當(dang)的單筒(tong)(tong)(tong)的30-35%。從而大幅度地減(jian)少占地面(mian)積(ji)和廠房建筑面(mian)積(ji)。
該機(ji)(ji)的支承裝置，是(shi)在外筒(tong)上(shang)輪帶與托(tuo)輪支承，由電(dian)機(ji)(ji)直接帶動(dong)托(tuo)輪。通過托(tuo)輪與輪帶摩擦，使筒(tong)體轉動(dong)。該機(ji)(ji)總體結構緊湊、合理、簡單(dan)，為便(bian)于磨損件的檢修更換(huan)，在中間設(she)計成軸向(xiang)剖分式，用螺栓固定(ding)連接。
工作原理
物(wu)(wu)料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝置進(jin)(jin)入回轉滾(gun)(gun)筒的內(nei)層(ceng)(ceng),實(shi)現順流烘干(gan)(gan),物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)內(nei)層(ceng)(ceng)的抄板下(xia)不斷(duan)抄起、散(san)落呈(cheng)螺旋行進(jin)(jin)式實(shi)現熱(re)交換，物(wu)(wu)料(liao)(liao)(liao)移(yi)動至(zhi)內(nei)層(ceng)(ceng)的另一端(duan)進(jin)(jin)入中(zhong)層(ceng)(ceng)，進(jin)(jin)行逆流烘干(gan)(gan)，物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)不斷(duan)地(di)被反(fan)復揚進(jin)(jin)，呈(cheng)進(jin)(jin)兩步退(tui)一步的行進(jin)(jin)方(fang)式，物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)既充(chong)分吸收(shou)(shou)內(nei)層(ceng)(ceng)滾(gun)(gun)筒散(san)發的熱(re)量，又(you)吸收(shou)(shou)中(zhong)層(ceng)(ceng)滾(gun)(gun)筒的熱(re)量，同時又(you)延長(chang)了(le)干(gan)(gan)燥(zao)(zao)時間，物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)此達到干(gan)(gan)燥(zao)(zao)狀態。物(wu)(wu)料(liao)(liao)(liao)行至(zhi)中(zhong)層(ceng)(ceng)另一端(duan)而落入外層(ceng)(ceng)，物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)外層(ceng)(ceng)滾(gun)(gun)筒內(nei)呈(cheng)矩形多回路方(fang)式行進(jin)(jin)，達到干(gan)(gan)燥(zao)(zao)效(xiao)果(guo)的物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)熱(re)風作用下(xia)快(kuai)(kuai)速行進(jin)(jin)排出滾(gun)(gun)筒，沒有(you)達到干(gan)(gan)燥(zao)(zao)效(xiao)果(guo)的濕物(wu)(wu)料(liao)(liao)(liao)因自重而不能快(kuai)(kuai)速行進(jin)(jin)，物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)此矩形抄板內(nei)進(jin)(jin)行充(chong)分干(gan)(gan)燥(zao)(zao)，由此完(wan)成(cheng)干(gan)(gan)燥(zao)(zao)目的。
