產品概(gai)況
回轉式三(san)筒(tong)烘干(gan)機(ji)(ji)(ji)改進原(yuan)單筒(tong)烘干(gan)機(ji)(ji)(ji)內部結構,增加(jia)入機(ji)(ji)(ji)前濕料的預(yu)烘干(gan)和(he)延長(chang)濕料在機(ji)(ji)(ji)內烘干(gan)時間,再加(jia)上密封(feng)、保溫以及合理的配(pei)套措(cuo)施(shi),使烘干(gan)機(ji)(ji)(ji)生產能(neng)力與原(yuan)單筒(tong)式烘干(gan)機(ji)(ji)(ji)相比,提高48-80%,單位容積蒸發強度可達(da)120-180kg/m3,標準煤(mei)(mei)耗僅(jin)為6-8kg/t。其(qi)技術先進、運(yun)行(xing)參(can)數合理,操作簡(jian)單可行(xing),廣(guang)泛應用于各個行(xing)業的礦渣、粘土、煤(mei)(mei)。
產(chan)品結構
三(san)筒烘(hong)干機(ji)(ji)(ji)是通(tong)過(guo)對單(dan)筒烘(hong)干機(ji)(ji)(ji)的(de)單(dan)筒體(ti)改為套(tao)疊在一起的(de)三(san)筒,以縮短烘(hong)干機(ji)(ji)(ji)體(ti)的(de)外(wai)形尺寸(cun)。該機(ji)(ji)(ji)工作時,物(wu)料和熱(re)氣流(liu)依次(ci)進入內至外(wai)筒體(ti),在機(ji)(ji)(ji)體(ti)Z形往復折流(liu)后,充分利(li)用熱(re)能烘(hong)干物(wu)料后再(zai)卸出(chu)。
烘干機筒(tong)體(ti)部分由三(san)個同(tong)軸(zhou)水平放置的內(nei)、中(zhong)、外筒(tong)套疊組(zu)成,這就使(shi)筒(tong)體(ti)的截面(mian)(mian)得到充(chong)分的利用(yong)。其筒(tong)體(ti)外形總長(chang)度約(yue)為與之相當的單筒(tong)的30-35%。從而大(da)幅度地減(jian)少占地面(mian)(mian)積(ji)和(he)廠房建筑(zhu)面(mian)(mian)積(ji)。
該機的(de)支(zhi)承(cheng)裝置,是在外(wai)筒(tong)上輪(lun)帶與托輪(lun)支(zhi)承(cheng),由電(dian)機直接帶動(dong)托輪(lun)。通過托輪(lun)與輪(lun)帶摩(mo)擦,使筒(tong)體轉(zhuan)動(dong)。該機總體結(jie)構(gou)緊湊(cou)、合理、簡單,為(wei)便(bian)于磨損件的(de)檢修更換,在中間設(she)計(ji)成(cheng)軸(zhou)向剖分式,用(yong)螺栓固定(ding)連(lian)接。
工作原(yuan)理(li)
物料(liao)(liao)(liao)由(you)供料(liao)(liao)(liao)裝置進(jin)(jin)(jin)(jin)入回(hui)轉滾(gun)筒的內層(ceng)(ceng),實現順(shun)流烘(hong)(hong)干(gan)(gan),物料(liao)(liao)(liao)在(zai)(zai)內層(ceng)(ceng)的抄板下(xia)不斷(duan)抄起、散落(luo)呈(cheng)螺(luo)旋行(xing)(xing)進(jin)(jin)(jin)(jin)式實現熱(re)(re)交(jiao)換,物料(liao)(liao)(liao)移動至內層(ceng)(ceng)的另一(yi)(yi)端進(jin)(jin)(jin)(jin)入中(zhong)(zhong)層(ceng)(ceng),進(jin)(jin)(jin)(jin)行(xing)(xing)逆流烘(hong)(hong)干(gan)(gan),物料(liao)(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)不斷(duan)地被(bei)反復揚(yang)進(jin)(jin)(jin)(jin),呈(cheng)進(jin)(jin)(jin)(jin)兩步(bu)退一(yi)(yi)步(bu)的行(xing)(xing)進(jin)(jin)(jin)(jin)方式,物料(liao)(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)既充分吸收內層(ceng)(ceng)滾(gun)筒散發(fa)的熱(re)(re)量(liang),又吸收中(zhong)(zhong)層(ceng)(ceng)滾(gun)筒的熱(re)(re)量(liang),同時(shi)(shi)又延長了(le)干(gan)(gan)燥(zao)(zao)(zao)(zao)時(shi)(shi)間,物料(liao)(liao)(liao)在(zai)(zai)此(ci)達(da)到干(gan)(gan)燥(zao)(zao)(zao)(zao)狀態(tai)。物料(liao)(liao)(liao)行(xing)(xing)至中(zhong)(zhong)層(ceng)(ceng)另一(yi)(yi)端而落(luo)入外層(ceng)(ceng),物料(liao)(liao)(liao)在(zai)(zai)外層(ceng)(ceng)滾(gun)筒內呈(cheng)矩形(xing)多回(hui)路方式行(xing)(xing)進(jin)(jin)(jin)(jin),達(da)到干(gan)(gan)燥(zao)(zao)(zao)(zao)效果的物料(liao)(liao)(liao)在(zai)(zai)熱(re)(re)風(feng)作用下(xia)快速行(xing)(xing)進(jin)(jin)(jin)(jin)排(pai)出滾(gun)筒,沒(mei)有達(da)到干(gan)(gan)燥(zao)(zao)(zao)(zao)效果的濕(shi)物料(liao)(liao)(liao)因自重而不能快速行(xing)(xing)進(jin)(jin)(jin)(jin),物料(liao)(liao)(liao)在(zai)(zai)此(ci)矩形(xing)抄板內進(jin)(jin)(jin)(jin)行(xing)(xing)充分干(gan)(gan)燥(zao)(zao)(zao)(zao),由(you)此(ci)完(wan)成干(gan)(gan)燥(zao)(zao)(zao)(zao)目(mu)的。
