產(chan)品概況

三筒烘干機是在單筒回轉式烘干機基礎上改進的節能產品。

回轉式三筒烘(hong)干機(ji)(ji)(ji)改進(jin)原單筒烘(hong)干機(ji)(ji)(ji)內(nei)部結構(gou),增加(jia)入(ru)機(ji)(ji)(ji)前濕(shi)料(liao)的(de)預(yu)烘(hong)干和延長濕(shi)料(liao)在機(ji)(ji)(ji)內(nei)烘(hong)干時間,再(zai)加(jia)上(shang)密封、保(bao)溫(wen)以及合理的(de)配套措施,使烘(hong)干機(ji)(ji)(ji)生產能力與原單筒式烘(hong)干機(ji)(ji)(ji)相比,提(ti)高(gao)48-80%,單位容積蒸(zheng)發強度(du)可達(da)120-180kg/m3,標準煤耗僅為(wei)6-8kg/t。其(qi)技術先進(jin)、運行參數合理,操作簡單可行,廣泛應用(yong)于各個行業的(de)礦(kuang)渣、粘土、煤。


產(chan)品結構

三筒(tong)(tong)烘干機(ji)(ji)是通過對單(dan)筒(tong)(tong)烘干機(ji)(ji)的(de)單(dan)筒(tong)(tong)體(ti)改(gai)為套疊在一起的(de)三筒(tong)(tong),以縮短烘干機(ji)(ji)體(ti)的(de)外形尺寸。該機(ji)(ji)工作時,物(wu)料和熱氣流依次進入內至外筒(tong)(tong)體(ti),在機(ji)(ji)體(ti)Z形往復折(zhe)流后(hou),充分利用熱能烘干物(wu)料后(hou)再卸出。

烘干機筒(tong)體部分(fen)由三個同軸水平放置的(de)(de)內(nei)、中、外筒(tong)套疊組成,這就使筒(tong)體的(de)(de)截面得到充(chong)分(fen)的(de)(de)利用。其筒(tong)體外形(xing)總長度約為與之相(xiang)當的(de)(de)單筒(tong)的(de)(de)30-35%。從而大幅度地減少(shao)占地面積和廠(chang)房建筑面積。

該機(ji)的支承(cheng)裝置,是在(zai)外筒上輪(lun)(lun)帶(dai)與托(tuo)輪(lun)(lun)支承(cheng),由(you)電機(ji)直接(jie)帶(dai)動托(tuo)輪(lun)(lun)。通過托(tuo)輪(lun)(lun)與輪(lun)(lun)帶(dai)摩擦,使筒體(ti)轉動。該機(ji)總體(ti)結(jie)構緊湊、合理(li)、簡單,為便于磨損件的檢(jian)修更換,在(zai)中(zhong)間(jian)設計成軸(zhou)向剖分式(shi),用螺栓固(gu)定(ding)連接(jie)。


工(gong)作(zuo)原理(li)

物(wu)(wu)(wu)(wu)料由供料裝置進(jin)(jin)入回(hui)轉滾(gun)筒(tong)的(de)(de)內(nei)(nei)層(ceng)(ceng)(ceng),實(shi)(shi)現順(shun)流(liu)烘干(gan)(gan),物(wu)(wu)(wu)(wu)料在(zai)內(nei)(nei)層(ceng)(ceng)(ceng)的(de)(de)抄(chao)(chao)板下(xia)不(bu)斷抄(chao)(chao)起、散落(luo)呈(cheng)螺旋行(xing)(xing)(xing)進(jin)(jin)式(shi)實(shi)(shi)現熱(re)(re)交換(huan),物(wu)(wu)(wu)(wu)料移(yi)動(dong)至(zhi)內(nei)(nei)層(ceng)(ceng)(ceng)的(de)(de)另一(yi)端進(jin)(jin)入中(zhong)(zhong)層(ceng)(ceng)(ceng),進(jin)(jin)行(xing)(xing)(xing)逆流(liu)烘干(gan)(gan),物(wu)(wu)(wu)(wu)料在(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)不(bu)斷地(di)被(bei)反復揚進(jin)(jin),呈(cheng)進(jin)(jin)兩(liang)步退一(yi)步的(de)(de)行(xing)(xing)(xing)進(jin)(jin)方(fang)式(shi),物(wu)(wu)(wu)(wu)料在(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)既充(chong)(chong)分吸收內(nei)(nei)層(ceng)(ceng)(ceng)滾(gun)筒(tong)散發的(de)(de)熱(re)(re)量(liang)(liang),又(you)(you)吸收中(zhong)(zhong)層(ceng)(ceng)(ceng)滾(gun)筒(tong)的(de)(de)熱(re)(re)量(liang)(liang),同時(shi)又(you)(you)延長(chang)了(le)干(gan)(gan)燥(zao)(zao)時(shi)間,物(wu)(wu)(wu)(wu)料在(zai)此達(da)到(dao)(dao)(dao)干(gan)(gan)燥(zao)(zao)狀態。物(wu)(wu)(wu)(wu)料行(xing)(xing)(xing)至(zhi)中(zhong)(zhong)層(ceng)(ceng)(ceng)另一(yi)端而落(luo)入外層(ceng)(ceng)(ceng),物(wu)(wu)(wu)(wu)料在(zai)外層(ceng)(ceng)(ceng)滾(gun)筒(tong)內(nei)(nei)呈(cheng)矩(ju)形(xing)多回(hui)路方(fang)式(shi)行(xing)(xing)(xing)進(jin)(jin),達(da)到(dao)(dao)(dao)干(gan)(gan)燥(zao)(zao)效果的(de)(de)物(wu)(wu)(wu)(wu)料在(zai)熱(re)(re)風作用下(xia)快(kuai)速行(xing)(xing)(xing)進(jin)(jin)排出滾(gun)筒(tong),沒有達(da)到(dao)(dao)(dao)干(gan)(gan)燥(zao)(zao)效果的(de)(de)濕物(wu)(wu)(wu)(wu)料因自重而不(bu)能快(kuai)速行(xing)(xing)(xing)進(jin)(jin),物(wu)(wu)(wu)(wu)料在(zai)此矩(ju)形(xing)抄(chao)(chao)板內(nei)(nei)進(jin)(jin)行(xing)(xing)(xing)充(chong)(chong)分干(gan)(gan)燥(zao)(zao),由此完成(cheng)干(gan)(gan)燥(zao)(zao)目的(de)(de)。
