產品概況
回轉式三筒烘(hong)(hong)干(gan)機(ji)(ji)改進(jin)原單(dan)(dan)筒烘(hong)(hong)干(gan)機(ji)(ji)內部結構(gou)，增(zeng)加入(ru)機(ji)(ji)前(qian)濕料(liao)的預烘(hong)(hong)干(gan)和延長濕料(liao)在(zai)機(ji)(ji)內烘(hong)(hong)干(gan)時間，再加上(shang)密封、保溫(wen)以及合理(li)的配套(tao)措施，使烘(hong)(hong)干(gan)機(ji)(ji)生(sheng)產能力與原單(dan)(dan)筒式烘(hong)(hong)干(gan)機(ji)(ji)相比，提(ti)高48-80%，單(dan)(dan)位容積(ji)蒸發(fa)強(qiang)度可達120-180kg/m3，標準煤耗僅為(wei)6-8kg/t。其技術先進(jin)、運(yun)行(xing)參(can)數合理(li)，操作簡單(dan)(dan)可行(xing)，廣泛應(ying)用于(yu)各(ge)個行(xing)業的礦(kuang)渣、粘土、煤。
產品(pin)結構
三筒(tong)(tong)烘干(gan)(gan)機是通(tong)過對單筒(tong)(tong)烘干(gan)(gan)機的(de)單筒(tong)(tong)體改為套(tao)疊在一起的(de)三筒(tong)(tong)，以(yi)縮短烘干(gan)(gan)機體的(de)外形(xing)尺寸。該機工作時(shi)，物料和熱(re)氣流依次進入內至外筒(tong)(tong)體，在機體Z形(xing)往復折(zhe)流后，充分(fen)利用(yong)熱(re)能烘干(gan)(gan)物料后再卸出。
烘干機筒(tong)體部(bu)分由三個同軸(zhou)水平放置的內、中(zhong)、外筒(tong)套(tao)疊組成，這就使筒(tong)體的截(jie)面(mian)得到充分的利用。其筒(tong)體外形總長度約為與之相當的單筒(tong)的30-35%。從而(er)大幅度地(di)減少(shao)占地(di)面(mian)積(ji)和廠(chang)房(fang)建筑面(mian)積(ji)。
該(gai)機的支承裝置，是在(zai)外筒(tong)上輪帶(dai)與(yu)托(tuo)輪支承，由(you)電機直接(jie)帶(dai)動(dong)托(tuo)輪。通過托(tuo)輪與(yu)輪帶(dai)摩擦，使筒(tong)體(ti)轉(zhuan)動(dong)。該(gai)機總體(ti)結構緊湊、合理(li)、簡單，為(wei)便(bian)于磨損(sun)件的檢(jian)修更換，在(zai)中間設計成軸向(xiang)剖分(fen)式，用螺栓固定連接(jie)。
工作原理
物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝(zhuang)置進(jin)(jin)(jin)入回(hui)轉滾(gun)筒(tong)的(de)內(nei)層(ceng)(ceng)(ceng)(ceng),實(shi)現(xian)(xian)順(shun)流(liu)烘(hong)干(gan),物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)抄(chao)板下(xia)不(bu)斷抄(chao)起、散落呈(cheng)(cheng)螺(luo)旋行(xing)進(jin)(jin)(jin)式實(shi)現(xian)(xian)熱交換，物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)移動至內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)另(ling)一端(duan)進(jin)(jin)(jin)入中(zhong)層(ceng)(ceng)(ceng)(ceng)，進(jin)(jin)(jin)行(xing)逆(ni)流(liu)烘(hong)干(gan)，物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)不(bu)斷地被反(fan)復揚(yang)進(jin)(jin)(jin)，呈(cheng)(cheng)進(jin)(jin)(jin)兩步(bu)退(tui)一步(bu)的(de)行(xing)進(jin)(jin)(jin)方式，物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)(ceng)既充分吸(xi)收(shou)內(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)散發(fa)的(de)熱量(liang)，又(you)吸(xi)收(shou)中(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)的(de)熱量(liang)，同時又(you)延(yan)長了干(gan)燥(zao)(zao)時間，物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)此達(da)到干(gan)燥(zao)(zao)狀(zhuang)態(tai)。物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)行(xing)至中(zhong)層(ceng)(ceng)(ceng)(ceng)另(ling)一端(duan)而(er)落入外層(ceng)(ceng)(ceng)(ceng)，物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)內(nei)呈(cheng)(cheng)矩形多(duo)回(hui)路方式行(xing)進(jin)(jin)(jin)，達(da)到干(gan)燥(zao)(zao)效(xiao)果(guo)的(de)物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)熱風作用(yong)下(xia)快(kuai)速行(xing)進(jin)(jin)(jin)排出滾(gun)筒(tong)，沒有達(da)到干(gan)燥(zao)(zao)效(xiao)果(guo)的(de)濕物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)因(yin)自(zi)重(zhong)而(er)不(bu)能快(kuai)速行(xing)進(jin)(jin)(jin)，物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)此矩形抄(chao)板內(nei)進(jin)(jin)(jin)行(xing)充分干(gan)燥(zao)(zao)，由此完成干(gan)燥(zao)(zao)目的(de)。
