產品概況
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。
產品(pin)結構
三筒(tong)式(shi)烘干機(ji)(ji)(ji)是通(tong)過(guo)對單(dan)(dan)筒(tong)烘干機(ji)(ji)(ji)的單(dan)(dan)筒(tong)體改為(wei)套疊(die)在一(yi)起的三筒(tong),以縮短烘干機(ji)(ji)(ji)體的外形尺寸(cun)。該機(ji)(ji)(ji)工作(zuo)時,物料和熱(re)氣流依次進入(ru)內至外筒(tong)體,在機(ji)(ji)(ji)體Z形往復折流后(hou),充分(fen)利(li)用(yong)熱(re)能烘干物料后(hou)再卸出。
烘干機筒(tong)(tong)(tong)體部分由(you)三個同(tong)軸(zhou)水平(ping)放置(zhi)的(de)內、中、外筒(tong)(tong)(tong)套疊組成,這(zhe)就(jiu)使(shi)筒(tong)(tong)(tong)體的(de)截面得到充分的(de)利用。其筒(tong)(tong)(tong)體外形總(zong)長度約為與之相當的(de)單筒(tong)(tong)(tong)的(de)30-35%。從而大幅度地減(jian)少占地面積和廠房建筑(zhu)面積。
該機(ji)的支承(cheng)裝置,是(shi)在外筒上輪(lun)帶與托輪(lun)支承(cheng),由電(dian)機(ji)直(zhi)接帶動(dong)托輪(lun)。通過托輪(lun)與輪(lun)帶摩(mo)擦(ca),使筒體轉動(dong)。該機(ji)總體結(jie)構(gou)緊(jin)湊、合理、簡單,為便于磨損件的檢修(xiu)更換,在中間設計成軸向剖分(fen)式,用螺(luo)栓固定連接。
工作原理(li)
物(wu)料(liao)(liao)由供料(liao)(liao)裝置進(jin)(jin)(jin)(jin)入(ru)回轉滾(gun)筒的(de)(de)(de)內(nei)(nei)(nei)層(ceng)(ceng),實(shi)現(xian)順流(liu)烘(hong)干(gan)(gan)(gan)(gan),物(wu)料(liao)(liao)在(zai)內(nei)(nei)(nei)層(ceng)(ceng)的(de)(de)(de)抄(chao)板(ban)下不(bu)斷(duan)抄(chao)起、散落(luo)呈(cheng)螺旋行(xing)進(jin)(jin)(jin)(jin)式實(shi)現(xian)熱交換,物(wu)料(liao)(liao)移(yi)動至(zhi)(zhi)內(nei)(nei)(nei)層(ceng)(ceng)的(de)(de)(de)另一端進(jin)(jin)(jin)(jin)入(ru)中(zhong)(zhong)(zhong)(zhong)層(ceng)(ceng),進(jin)(jin)(jin)(jin)行(xing)逆(ni)流(liu)烘(hong)干(gan)(gan)(gan)(gan),物(wu)料(liao)(liao)在(zai)中(zhong)(zhong)(zhong)(zhong)層(ceng)(ceng)不(bu)斷(duan)地被(bei)反復揚進(jin)(jin)(jin)(jin),呈(cheng)進(jin)(jin)(jin)(jin)兩步(bu)退一步(bu)的(de)(de)(de)行(xing)進(jin)(jin)(jin)(jin)方式,物(wu)料(liao)(liao)在(zai)中(zhong)(zhong)(zhong)(zhong)層(ceng)(ceng)既充分吸收內(nei)(nei)(nei)層(ceng)(ceng)滾(gun)筒散發的(de)(de)(de)熱量(liang),又(you)吸收中(zhong)(zhong)(zhong)(zhong)層(ceng)(ceng)滾(gun)筒的(de)(de)(de)熱量(liang),同時又(you)延長了干(gan)(gan)(gan)(gan)燥(zao)時間,物(wu)料(liao)(liao)在(zai)此(ci)(ci)達到(dao)干(gan)(gan)(gan)(gan)燥(zao)狀(zhuang)態。物(wu)料(liao)(liao)行(xing)至(zhi)(zhi)中(zhong)(zhong)(zhong)(zhong)層(ceng)(ceng)另一端而落(luo)入(ru)外層(ceng)(ceng),物(wu)料(liao)(liao)在(zai)外層(ceng)(ceng)滾(gun)筒內(nei)(nei)(nei)呈(cheng)矩(ju)形(xing)多回路方式行(xing)進(jin)(jin)(jin)(jin),達到(dao)干(gan)(gan)(gan)(gan)燥(zao)效(xiao)果(guo)的(de)(de)(de)物(wu)料(liao)(liao)在(zai)熱風作用下快速(su)行(xing)進(jin)(jin)(jin)(jin)排出滾(gun)筒,沒有達到(dao)干(gan)(gan)(gan)(gan)燥(zao)效(xiao)果(guo)的(de)(de)(de)濕(shi)物(wu)料(liao)(liao)因自(zi)重而不(bu)能快速(su)行(xing)進(jin)(jin)(jin)(jin),物(wu)料(liao)(liao)在(zai)此(ci)(ci)矩(ju)形(xing)抄(chao)板(ban)內(nei)(nei)(nei)進(jin)(jin)(jin)(jin)行(xing)充分干(gan)(gan)(gan)(gan)燥(zao),由此(ci)(ci)完(wan)成(cheng)干(gan)(gan)(gan)(gan)燥(zao)目的(de)(de)(de)。
