產品(pin)概況(kuang)
回轉式三筒烘(hong)(hong)干(gan)機(ji)(ji)(ji)改進原單(dan)筒烘(hong)(hong)干(gan)機(ji)(ji)(ji)內部結構,增加(jia)入機(ji)(ji)(ji)前濕料的預(yu)烘(hong)(hong)干(gan)和延長濕料在機(ji)(ji)(ji)內烘(hong)(hong)干(gan)時間(jian),再加(jia)上密封(feng)、保溫以(yi)及合理的配套措施,使烘(hong)(hong)干(gan)機(ji)(ji)(ji)生產(chan)能力(li)與原單(dan)筒式烘(hong)(hong)干(gan)機(ji)(ji)(ji)相比,提高48-80%,單(dan)位(wei)容積(ji)蒸發強度可(ke)達120-180kg/m3,標準煤耗僅為6-8kg/t。其技術先進、運(yun)行參(can)數合理,操作簡單(dan)可(ke)行,廣泛應用于各個行業的礦(kuang)渣、粘(zhan)土、煤。
產品結構
三筒(tong)烘(hong)(hong)(hong)干機(ji)是通(tong)過對(dui)單(dan)筒(tong)烘(hong)(hong)(hong)干機(ji)的單(dan)筒(tong)體(ti)(ti)改為套(tao)疊在一(yi)起的三筒(tong),以縮(suo)短(duan)烘(hong)(hong)(hong)干機(ji)體(ti)(ti)的外形尺寸。該機(ji)工(gong)作時,物(wu)料和熱氣流依次進(jin)入(ru)內至外筒(tong)體(ti)(ti),在機(ji)體(ti)(ti)Z形往(wang)復折流后,充分利用熱能(neng)烘(hong)(hong)(hong)干物(wu)料后再(zai)卸出。
烘干機筒體部分由(you)三個同軸水平(ping)放(fang)置的內(nei)、中、外筒套疊組成,這就使(shi)筒體的截(jie)面得(de)到充分的利用。其筒體外形總長度(du)(du)約(yue)為與之相當的單筒的30-35%。從而大幅度(du)(du)地(di)減少占地(di)面積和廠房建筑面積。
該機的支(zhi)承裝置,是在外筒上輪(lun)帶與(yu)托(tuo)輪(lun)支(zhi)承,由電機直接帶動(dong)托(tuo)輪(lun)。通過(guo)托(tuo)輪(lun)與(yu)輪(lun)帶摩擦,使筒體(ti)轉動(dong)。該機總(zong)體(ti)結(jie)構緊湊、合理、簡單(dan),為(wei)便(bian)于磨損件的檢修更換,在中間設(she)計(ji)成軸(zhou)向剖(pou)分式,用螺栓固(gu)定連接。
工作原理(li)
物(wu)(wu)(wu)料(liao)(liao)(liao)由(you)供料(liao)(liao)(liao)裝置進(jin)入(ru)回轉(zhuan)滾筒(tong)(tong)的(de)(de)(de)內(nei)層(ceng)(ceng),實(shi)現順流烘干(gan)(gan)(gan)(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)內(nei)層(ceng)(ceng)的(de)(de)(de)抄板(ban)下不(bu)斷抄起、散落(luo)呈(cheng)螺旋(xuan)行(xing)(xing)進(jin)式實(shi)現熱交換,物(wu)(wu)(wu)料(liao)(liao)(liao)移動至(zhi)內(nei)層(ceng)(ceng)的(de)(de)(de)另一端進(jin)入(ru)中(zhong)(zhong)層(ceng)(ceng),進(jin)行(xing)(xing)逆流烘干(gan)(gan)(gan)(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)不(bu)斷地被反復揚進(jin),呈(cheng)進(jin)兩步退(tui)一步的(de)(de)(de)行(xing)(xing)進(jin)方(fang)式,物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)既充分(fen)(fen)吸收內(nei)層(ceng)(ceng)滾筒(tong)(tong)散發的(de)(de)(de)熱量,又吸收中(zhong)(zhong)層(ceng)(ceng)滾筒(tong)(tong)的(de)(de)(de)熱量,同(tong)時又延長了干(gan)(gan)(gan)(gan)(gan)燥(zao)(zao)(zao)時間,物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)此達(da)到干(gan)(gan)(gan)(gan)(gan)燥(zao)(zao)(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)(liao)行(xing)(xing)至(zhi)中(zhong)(zhong)層(ceng)(ceng)另一端而落(luo)入(ru)外層(ceng)(ceng),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)外層(ceng)(ceng)滾筒(tong)(tong)內(nei)呈(cheng)矩形多回路方(fang)式行(xing)(xing)進(jin),達(da)到干(gan)(gan)(gan)(gan)(gan)燥(zao)(zao)(zao)效(xiao)果的(de)(de)(de)物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)熱風作(zuo)用下快(kuai)(kuai)速行(xing)(xing)進(jin)排出滾筒(tong)(tong),沒有(you)達(da)到干(gan)(gan)(gan)(gan)(gan)燥(zao)(zao)(zao)效(xiao)果的(de)(de)(de)濕物(wu)(wu)(wu)料(liao)(liao)(liao)因自重而不(bu)能快(kuai)(kuai)速行(xing)(xing)進(jin),物(wu)(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)此矩形抄板(ban)內(nei)進(jin)行(xing)(xing)充分(fen)(fen)干(gan)(gan)(gan)(gan)(gan)燥(zao)(zao)(zao),由(you)此完成干(gan)(gan)(gan)(gan)(gan)燥(zao)(zao)(zao)目的(de)(de)(de)。
