濰坊三筒式烘干機

詳細介紹

三筒式烘干機

產品概況

三筒式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)品結構

三(san)筒式烘(hong)干(gan)(gan)機(ji)是通過對單筒烘(hong)干(gan)(gan)機(ji)的單筒體(ti)(ti)改為套疊在一起的三(san)筒,以縮(suo)短烘(hong)干(gan)(gan)機(ji)體(ti)(ti)的外形尺寸。該(gai)機(ji)工作時,物料和熱(re)氣流依次進入內至外筒體(ti)(ti),在機(ji)體(ti)(ti)Z形往復(fu)折流后(hou),充分利用(yong)熱(re)能烘(hong)干(gan)(gan)物料后(hou)再卸(xie)出。

烘(hong)干機筒(tong)體(ti)部分由三個同(tong)軸(zhou)水(shui)平放置(zhi)的(de)內(nei)、中、外筒(tong)套疊(die)組(zu)成,這就(jiu)使筒(tong)體(ti)的(de)截面(mian)得到充分的(de)利用。其筒(tong)體(ti)外形總長度約為與之相當的(de)單筒(tong)的(de)30-35%。從而大幅度地減少(shao)占地面(mian)積(ji)和(he)廠房建(jian)筑面(mian)積(ji)。

該(gai)機(ji)的支承裝置,是(shi)在外筒(tong)上輪(lun)帶(dai)與(yu)托輪(lun)支承,由電(dian)機(ji)直(zhi)接帶(dai)動(dong)托輪(lun)。通過(guo)托輪(lun)與(yu)輪(lun)帶(dai)摩擦,使筒(tong)體轉動(dong)。該(gai)機(ji)總體結(jie)構緊湊、合理、簡(jian)單,為(wei)便于磨損件的檢修更(geng)換,在中間設計成軸向(xiang)剖分式(shi),用(yong)螺栓固定連接。


工作(zuo)原理

物(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝(zhuang)置進(jin)(jin)(jin)入回(hui)轉滾(gun)(gun)筒(tong)(tong)(tong)的(de)(de)內(nei)層(ceng)(ceng)(ceng)(ceng),實(shi)現順(shun)流烘干(gan)(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)抄板下不斷抄起、散落(luo)呈(cheng)螺旋行(xing)(xing)進(jin)(jin)(jin)式實(shi)現熱(re)交(jiao)換,物(wu)(wu)(wu)料(liao)(liao)移動(dong)至內(nei)層(ceng)(ceng)(ceng)(ceng)的(de)(de)另一端(duan)進(jin)(jin)(jin)入中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng),進(jin)(jin)(jin)行(xing)(xing)逆(ni)流烘干(gan)(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)不斷地(di)被反復揚進(jin)(jin)(jin),呈(cheng)進(jin)(jin)(jin)兩步退一步的(de)(de)行(xing)(xing)進(jin)(jin)(jin)方式,物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)既充分(fen)吸收內(nei)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)(tong)散發的(de)(de)熱(re)量,又(you)吸收中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)(tong)的(de)(de)熱(re)量,同時又(you)延長了(le)干(gan)(gan)(gan)燥(zao)時間,物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)此達到(dao)干(gan)(gan)(gan)燥(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)行(xing)(xing)至中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)另一端(duan)而落(luo)入外層(ceng)(ceng)(ceng)(ceng),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)外層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)(tong)內(nei)呈(cheng)矩形(xing)多回(hui)路方式行(xing)(xing)進(jin)(jin)(jin),達到(dao)干(gan)(gan)(gan)燥(zao)效果的(de)(de)物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)熱(re)風(feng)作(zuo)用(yong)下快(kuai)(kuai)速行(xing)(xing)進(jin)(jin)(jin)排出滾(gun)(gun)筒(tong)(tong)(tong),沒有達到(dao)干(gan)(gan)(gan)燥(zao)效果的(de)(de)濕物(wu)(wu)(wu)料(liao)(liao)因(yin)自重而不能快(kuai)(kuai)速行(xing)(xing)進(jin)(jin)(jin),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)(zai)此矩形(xing)抄板內(nei)進(jin)(jin)(jin)行(xing)(xing)充分(fen)干(gan)(gan)(gan)燥(zao),由此完成(cheng)干(gan)(gan)(gan)燥(zao)目(mu)的(de)(de)。
