產品(pin)概(gai)況
回轉式(shi)三筒(tong)烘干(gan)機(ji)(ji)改進(jin)原單(dan)(dan)筒(tong)烘干(gan)機(ji)(ji)內部結構,增加入機(ji)(ji)前濕料的預烘干(gan)和延(yan)長濕料在機(ji)(ji)內烘干(gan)時間,再加上密封、保溫以及合(he)理的配套措施(shi),使(shi)烘干(gan)機(ji)(ji)生產能力與(yu)原單(dan)(dan)筒(tong)式(shi)烘干(gan)機(ji)(ji)相比(bi),提高(gao)48-80%,單(dan)(dan)位容積蒸發(fa)強(qiang)度可達120-180kg/m3,標準(zhun)煤(mei)耗僅(jin)為6-8kg/t。其技(ji)術(shu)先進(jin)、運行參數(shu)合(he)理,操作簡單(dan)(dan)可行,廣(guang)泛應(ying)用于各個(ge)行業的礦渣、粘土、煤(mei)。
產品結構
三筒烘干機(ji)是(shi)通過對單(dan)筒烘干機(ji)的(de)(de)單(dan)筒體改為(wei)套疊在一起的(de)(de)三筒,以縮短(duan)烘干機(ji)體的(de)(de)外形(xing)尺寸(cun)。該(gai)機(ji)工作時,物料(liao)和熱氣流依次進入內至外筒體,在機(ji)體Z形(xing)往復折流后,充分利(li)用熱能烘干物料(liao)后再卸出。
烘干機筒(tong)(tong)體(ti)部分由三個同軸(zhou)水平放置的內、中、外(wai)筒(tong)(tong)套疊組成,這就使(shi)筒(tong)(tong)體(ti)的截面得(de)到充分的利用。其筒(tong)(tong)體(ti)外(wai)形總(zong)長度約為與(yu)之相當的單筒(tong)(tong)的30-35%。從(cong)而(er)大幅度地減少占地面積和廠(chang)房建筑面積。
該(gai)機(ji)的支承裝(zhuang)置(zhi),是(shi)在外筒(tong)上輪(lun)帶(dai)與(yu)托輪(lun)支承,由電機(ji)直(zhi)接(jie)帶(dai)動托輪(lun)。通過托輪(lun)與(yu)輪(lun)帶(dai)摩擦(ca),使筒(tong)體轉動。該(gai)機(ji)總體結(jie)構緊湊、合理、簡單,為便于磨損件的檢修更換,在中間設計成軸向剖分式,用螺栓固(gu)定(ding)連接(jie)。
工(gong)作原理
物(wu)料(liao)由(you)(you)供料(liao)裝置進(jin)入回轉滾(gun)(gun)(gun)(gun)筒(tong)(tong)的內(nei)層(ceng)(ceng)(ceng),實現順(shun)流(liu)烘(hong)干,物(wu)料(liao)在內(nei)層(ceng)(ceng)(ceng)的抄板(ban)下(xia)不(bu)斷抄起、散落呈螺旋行(xing)(xing)進(jin)式實現熱交換,物(wu)料(liao)移動至內(nei)層(ceng)(ceng)(ceng)的另一(yi)(yi)端(duan)進(jin)入中層(ceng)(ceng)(ceng),進(jin)行(xing)(xing)逆(ni)流(liu)烘(hong)干,物(wu)料(liao)在中層(ceng)(ceng)(ceng)不(bu)斷地被(bei)反復(fu)揚進(jin),呈進(jin)兩步退一(yi)(yi)步的行(xing)(xing)進(jin)方式,物(wu)料(liao)在中層(ceng)(ceng)(ceng)既(ji)充(chong)分(fen)吸收(shou)內(nei)層(ceng)(ceng)(ceng)滾(gun)(gun)(gun)(gun)筒(tong)(tong)散發(fa)的熱量,又吸收(shou)中層(ceng)(ceng)(ceng)滾(gun)(gun)(gun)(gun)筒(tong)(tong)的熱量,同時(shi)又延(yan)長了干燥(zao)(zao)時(shi)間,物(wu)料(liao)在此(ci)(ci)達(da)到干燥(zao)(zao)狀態(tai)。物(wu)料(liao)行(xing)(xing)至中層(ceng)(ceng)(ceng)另一(yi)(yi)端(duan)而落入外層(ceng)(ceng)(ceng),物(wu)料(liao)在外層(ceng)(ceng)(ceng)滾(gun)(gun)(gun)(gun)筒(tong)(tong)內(nei)呈矩形(xing)多(duo)回路方式行(xing)(xing)進(jin),達(da)到干燥(zao)(zao)效(xiao)果(guo)的物(wu)料(liao)在熱風作(zuo)用(yong)下(xia)快速(su)行(xing)(xing)進(jin)排(pai)出滾(gun)(gun)(gun)(gun)筒(tong)(tong),沒有達(da)到干燥(zao)(zao)效(xiao)果(guo)的濕(shi)物(wu)料(liao)因(yin)自重而不(bu)能快速(su)行(xing)(xing)進(jin),物(wu)料(liao)在此(ci)(ci)矩形(xing)抄板(ban)內(nei)進(jin)行(xing)(xing)充(chong)分(fen)干燥(zao)(zao),由(you)(you)此(ci)(ci)完成(cheng)干燥(zao)(zao)目(mu)的。
