產品(pin)概況
回轉式三筒(tong)烘(hong)(hong)(hong)干機改進(jin)原單筒(tong)烘(hong)(hong)(hong)干機內部結構,增加(jia)入機前濕料的(de)預(yu)烘(hong)(hong)(hong)干和延長(chang)濕料在機內烘(hong)(hong)(hong)干時(shi)間,再加(jia)上密封、保(bao)溫以(yi)及合(he)(he)理的(de)配套措(cuo)施,使烘(hong)(hong)(hong)干機生(sheng)產(chan)能力與原單筒(tong)式烘(hong)(hong)(hong)干機相比,提(ti)高(gao)48-80%,單位(wei)容積(ji)蒸發(fa)強度可達(da)120-180kg/m3,標準煤耗僅(jin)為6-8kg/t。其技術先進(jin)、運行(xing)參數合(he)(he)理,操(cao)作簡單可行(xing),廣泛應用于各個行(xing)業的(de)礦(kuang)渣、粘土、煤。
產(chan)品結構
三筒(tong)(tong)烘干機(ji)(ji)(ji)是通過(guo)對(dui)單(dan)筒(tong)(tong)烘干機(ji)(ji)(ji)的單(dan)筒(tong)(tong)體(ti)改為套疊在(zai)一起的三筒(tong)(tong),以縮短(duan)烘干機(ji)(ji)(ji)體(ti)的外形(xing)尺(chi)寸。該機(ji)(ji)(ji)工作時,物(wu)料(liao)和熱(re)氣(qi)流依次進入內至外筒(tong)(tong)體(ti),在(zai)機(ji)(ji)(ji)體(ti)Z形(xing)往(wang)復(fu)折流后(hou),充分利用熱(re)能(neng)烘干物(wu)料(liao)后(hou)再卸出。
烘干機筒(tong)體(ti)部(bu)分由三個(ge)同軸(zhou)水平放置的內、中、外(wai)筒(tong)套(tao)疊組成,這就使筒(tong)體(ti)的截面得到(dao)充(chong)分的利(li)用。其筒(tong)體(ti)外(wai)形總長度約為與之相(xiang)當的單(dan)筒(tong)的30-35%。從而大幅(fu)度地(di)減少占地(di)面積(ji)和廠房建筑面積(ji)。
該機(ji)(ji)的支承裝置,是(shi)在外筒上(shang)輪(lun)帶與托(tuo)輪(lun)支承,由電(dian)機(ji)(ji)直接帶動托(tuo)輪(lun)。通過(guo)托(tuo)輪(lun)與輪(lun)帶摩擦,使筒體(ti)轉動。該機(ji)(ji)總體(ti)結構緊湊、合理(li)、簡單,為(wei)便于磨損件(jian)的檢修更換,在中間設計成軸向剖分式(shi),用螺(luo)栓固定連接。
工作原理(li)
物(wu)(wu)料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝置進(jin)(jin)(jin)入回(hui)轉滾(gun)(gun)筒(tong)(tong)的(de)內(nei)(nei)層(ceng)(ceng)(ceng),實現(xian)順流(liu)烘干(gan),物(wu)(wu)料(liao)(liao)(liao)在(zai)內(nei)(nei)層(ceng)(ceng)(ceng)的(de)抄(chao)(chao)板下不(bu)斷抄(chao)(chao)起、散落呈(cheng)(cheng)螺旋行(xing)(xing)(xing)進(jin)(jin)(jin)式實現(xian)熱交換,物(wu)(wu)料(liao)(liao)(liao)移(yi)動至內(nei)(nei)層(ceng)(ceng)(ceng)的(de)另一(yi)端(duan)(duan)進(jin)(jin)(jin)入中(zhong)(zhong)層(ceng)(ceng)(ceng),進(jin)(jin)(jin)行(xing)(xing)(xing)逆流(liu)烘干(gan),物(wu)(wu)料(liao)(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)不(bu)斷地被反(fan)復揚進(jin)(jin)(jin),呈(cheng)(cheng)進(jin)(jin)(jin)兩步(bu)退一(yi)步(bu)的(de)行(xing)(xing)(xing)進(jin)(jin)(jin)方(fang)式,物(wu)(wu)料(liao)(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)既充分吸收(shou)內(nei)(nei)層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)散發(fa)的(de)熱量,又(you)吸收(shou)中(zhong)(zhong)層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)的(de)熱量,同時又(you)延長了干(gan)燥(zao)時間,物(wu)(wu)料(liao)(liao)(liao)在(zai)此(ci)達(da)到(dao)干(gan)燥(zao)狀態。物(wu)(wu)料(liao)(liao)(liao)行(xing)(xing)(xing)至中(zhong)(zhong)層(ceng)(ceng)(ceng)另一(yi)端(duan)(duan)而落入外層(ceng)(ceng)(ceng),物(wu)(wu)料(liao)(liao)(liao)在(zai)外層(ceng)(ceng)(ceng)滾(gun)(gun)筒(tong)(tong)內(nei)(nei)呈(cheng)(cheng)矩(ju)(ju)形多回(hui)路(lu)方(fang)式行(xing)(xing)(xing)進(jin)(jin)(jin),達(da)到(dao)干(gan)燥(zao)效果的(de)物(wu)(wu)料(liao)(liao)(liao)在(zai)熱風作用下快速行(xing)(xing)(xing)進(jin)(jin)(jin)排出滾(gun)(gun)筒(tong)(tong),沒(mei)有達(da)到(dao)干(gan)燥(zao)效果的(de)濕物(wu)(wu)料(liao)(liao)(liao)因自(zi)重而不(bu)能快速行(xing)(xing)(xing)進(jin)(jin)(jin),物(wu)(wu)料(liao)(liao)(liao)在(zai)此(ci)矩(ju)(ju)形抄(chao)(chao)板內(nei)(nei)進(jin)(jin)(jin)行(xing)(xing)(xing)充分干(gan)燥(zao),由此(ci)完成干(gan)燥(zao)目(mu)的(de)。
