產品(pin)概(gai)況
回轉(zhuan)式三筒烘(hong)(hong)干機改進原單(dan)筒烘(hong)(hong)干機內部結(jie)構(gou)，增加入機前濕料的預烘(hong)(hong)干和延長(chang)濕料在機內烘(hong)(hong)干時間，再加上密封、保(bao)溫(wen)以及合(he)理的配套措施，使烘(hong)(hong)干機生產能力與原單(dan)筒式烘(hong)(hong)干機相比(bi)，提高48-80%，單(dan)位容積蒸發強度(du)可達120-180kg/m3，標準煤(mei)(mei)耗(hao)僅為6-8kg/t。其技術先進、運行參(can)數合(he)理，操作(zuo)簡單(dan)可行，廣泛應(ying)用于各個行業的礦渣、粘土、煤(mei)(mei)。
產品結構
三筒(tong)(tong)烘(hong)干(gan)機(ji)(ji)是通(tong)過對單筒(tong)(tong)烘(hong)干(gan)機(ji)(ji)的單筒(tong)(tong)體改為套疊在一起的三筒(tong)(tong)，以(yi)縮短烘(hong)干(gan)機(ji)(ji)體的外形尺寸。該(gai)機(ji)(ji)工作時(shi)，物(wu)料(liao)(liao)和熱(re)氣流依(yi)次進入內至外筒(tong)(tong)體，在機(ji)(ji)體Z形往復(fu)折流后(hou)，充(chong)分利用熱(re)能烘(hong)干(gan)物(wu)料(liao)(liao)后(hou)再卸出。
烘干機筒(tong)(tong)(tong)體部分由三(san)個同軸水平放置的內、中、外筒(tong)(tong)(tong)套疊組(zu)成，這就(jiu)使筒(tong)(tong)(tong)體的截面得到充(chong)分的利用。其筒(tong)(tong)(tong)體外形總長度(du)約(yue)為(wei)與之(zhi)相(xiang)當的單筒(tong)(tong)(tong)的30-35%。從(cong)而大幅度(du)地減少占地面積(ji)和(he)廠房(fang)建筑(zhu)面積(ji)。
該(gai)機(ji)(ji)的支(zhi)承裝置，是在外筒(tong)上輪(lun)(lun)(lun)帶(dai)與托(tuo)輪(lun)(lun)(lun)支(zhi)承，由電(dian)機(ji)(ji)直接帶(dai)動托(tuo)輪(lun)(lun)(lun)。通(tong)過托(tuo)輪(lun)(lun)(lun)與輪(lun)(lun)(lun)帶(dai)摩(mo)擦，使筒(tong)體轉動。該(gai)機(ji)(ji)總體結構緊湊、合(he)理、簡單，為便(bian)于(yu)磨損件(jian)的檢修(xiu)更換(huan)，在中間設計成(cheng)軸向剖分式，用螺栓固定連接。
工作原(yuan)理
物(wu)(wu)料(liao)(liao)(liao)由(you)供料(liao)(liao)(liao)裝置進(jin)(jin)(jin)入回轉滾(gun)筒(tong)(tong)的(de)(de)內層(ceng)(ceng)(ceng),實現(xian)順(shun)流烘干(gan)(gan),物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)(zai)內層(ceng)(ceng)(ceng)的(de)(de)抄(chao)板(ban)下不(bu)(bu)斷抄(chao)起、散落呈(cheng)螺旋行(xing)進(jin)(jin)(jin)式實現(xian)熱交(jiao)換，物(wu)(wu)料(liao)(liao)(liao)移動至(zhi)內層(ceng)(ceng)(ceng)的(de)(de)另一(yi)端進(jin)(jin)(jin)入中層(ceng)(ceng)(ceng)，進(jin)(jin)(jin)行(xing)逆流烘干(gan)(gan)，物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)(zai)中層(ceng)(ceng)(ceng)不(bu)(bu)斷地(di)被反復(fu)揚進(jin)(jin)(jin)，呈(cheng)進(jin)(jin)(jin)兩步(bu)退(tui)一(yi)步(bu)的(de)(de)行(xing)進(jin)(jin)(jin)方式，物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)(zai)中層(ceng)(ceng)(ceng)既充分吸收(shou)內層(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)散發的(de)(de)熱量(liang)，又(you)吸收(shou)中層(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)的(de)(de)熱量(liang)，同時(shi)又(you)延(yan)長了(le)干(gan)(gan)燥(zao)時(shi)間(jian)，物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)(zai)此(ci)達到(dao)干(gan)(gan)燥(zao)狀態。物(wu)(wu)料(liao)(liao)(liao)行(xing)至(zhi)中層(ceng)(ceng)(ceng)另一(yi)端而落入外層(ceng)(ceng)(ceng)，物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)(zai)外層(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)內呈(cheng)矩形多回路方式行(xing)進(jin)(jin)(jin)，達到(dao)干(gan)(gan)燥(zao)效(xiao)果的(de)(de)物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)(zai)熱風作用下快速(su)(su)行(xing)進(jin)(jin)(jin)排出滾(gun)筒(tong)(tong)，沒有達到(dao)干(gan)(gan)燥(zao)效(xiao)果的(de)(de)濕物(wu)(wu)料(liao)(liao)(liao)因自重而不(bu)(bu)能(neng)快速(su)(su)行(xing)進(jin)(jin)(jin)，物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)(zai)(zai)此(ci)矩形抄(chao)板(ban)內進(jin)(jin)(jin)行(xing)充分干(gan)(gan)燥(zao)，由(you)此(ci)完成干(gan)(gan)燥(zao)目的(de)(de)。
