產品概況
回轉(zhuan)式(shi)三筒烘干機改進(jin)原單筒烘干機內部結構,增加(jia)入機前濕料的(de)(de)預烘干和延長濕料在(zai)機內烘干時間,再(zai)加(jia)上密封、保溫(wen)以(yi)及(ji)合理(li)的(de)(de)配套措(cuo)施,使(shi)烘干機生產(chan)能力與原單筒式(shi)烘干機相比,提高48-80%,單位容積(ji)蒸(zheng)發(fa)強度可(ke)達120-180kg/m3,標(biao)準煤耗僅為6-8kg/t。其技術先進(jin)、運(yun)行(xing)(xing)參數(shu)合理(li),操作簡單可(ke)行(xing)(xing),廣泛應(ying)用于各個行(xing)(xing)業的(de)(de)礦渣、粘土、煤。
產品結構
三(san)筒(tong)烘干(gan)機(ji)是通過對單筒(tong)烘干(gan)機(ji)的(de)單筒(tong)體改為(wei)套疊在一起的(de)三(san)筒(tong),以縮短(duan)烘干(gan)機(ji)體的(de)外形尺寸。該機(ji)工作時,物(wu)料和熱(re)(re)氣流依次(ci)進入內至外筒(tong)體,在機(ji)體Z形往復折流后,充分利用(yong)熱(re)(re)能烘干(gan)物(wu)料后再卸出。
烘干(gan)機筒(tong)(tong)體(ti)部(bu)分由三個同軸(zhou)水(shui)平放置(zhi)的(de)(de)(de)內、中(zhong)、外筒(tong)(tong)套疊組(zu)成,這就(jiu)使筒(tong)(tong)體(ti)的(de)(de)(de)截面得到充(chong)分的(de)(de)(de)利用。其筒(tong)(tong)體(ti)外形總(zong)長度約為與之相(xiang)當的(de)(de)(de)單筒(tong)(tong)的(de)(de)(de)30-35%。從而大幅度地減少占地面積和廠房建筑(zhu)面積。
該機的(de)支(zhi)承裝置,是(shi)在外筒上輪(lun)(lun)帶與(yu)托(tuo)輪(lun)(lun)支(zhi)承,由電(dian)機直接帶動托(tuo)輪(lun)(lun)。通過托(tuo)輪(lun)(lun)與(yu)輪(lun)(lun)帶摩擦,使筒體(ti)轉動。該機總(zong)體(ti)結構緊(jin)湊(cou)、合理、簡(jian)單(dan),為便于磨損件的(de)檢修(xiu)更(geng)換(huan),在中(zhong)間設計成軸向剖分式(shi),用螺栓固定連接。
工作(zuo)原理
物(wu)料(liao)(liao)由(you)供料(liao)(liao)裝(zhuang)置進入回轉滾(gun)(gun)筒的(de)(de)內層(ceng)(ceng)(ceng)(ceng),實現順流(liu)烘干(gan),物(wu)料(liao)(liao)在(zai)內層(ceng)(ceng)(ceng)(ceng)的(de)(de)抄板下(xia)不斷(duan)抄起、散落(luo)呈螺旋行(xing)(xing)進式實現熱交換,物(wu)料(liao)(liao)移動至內層(ceng)(ceng)(ceng)(ceng)的(de)(de)另(ling)(ling)一(yi)(yi)端(duan)進入中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng),進行(xing)(xing)逆流(liu)烘干(gan),物(wu)料(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)不斷(duan)地被反(fan)復揚進,呈進兩步退一(yi)(yi)步的(de)(de)行(xing)(xing)進方式,物(wu)料(liao)(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)既充分吸(xi)收(shou)內層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒散發的(de)(de)熱量(liang),又(you)吸(xi)收(shou)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒的(de)(de)熱量(liang),同(tong)時又(you)延(yan)長了(le)干(gan)燥(zao)時間,物(wu)料(liao)(liao)在(zai)此達(da)到干(gan)燥(zao)狀態。物(wu)料(liao)(liao)行(xing)(xing)至中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)另(ling)(ling)一(yi)(yi)端(duan)而落(luo)入外(wai)層(ceng)(ceng)(ceng)(ceng),物(wu)料(liao)(liao)在(zai)外(wai)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)筒內呈矩形(xing)多回路(lu)方式行(xing)(xing)進,達(da)到干(gan)燥(zao)效果(guo)的(de)(de)物(wu)料(liao)(liao)在(zai)熱風作用(yong)下(xia)快速行(xing)(xing)進排出滾(gun)(gun)筒,沒有達(da)到干(gan)燥(zao)效果(guo)的(de)(de)濕物(wu)料(liao)(liao)因自(zi)重(zhong)而不能快速行(xing)(xing)進,物(wu)料(liao)(liao)在(zai)此矩形(xing)抄板內進行(xing)(xing)充分干(gan)燥(zao),由(you)此完(wan)成干(gan)燥(zao)目的(de)(de)。
