產品概況
回轉式三(san)筒烘(hong)干機(ji)(ji)改進原單筒烘(hong)干機(ji)(ji)內(nei)部(bu)結構，增加(jia)入機(ji)(ji)前濕(shi)料的預(yu)烘(hong)干和延長濕(shi)料在機(ji)(ji)內(nei)烘(hong)干時間，再(zai)加(jia)上密(mi)封、保溫以及合理(li)的配套(tao)措(cuo)施，使烘(hong)干機(ji)(ji)生產能(neng)力與(yu)原單筒式烘(hong)干機(ji)(ji)相比，提高(gao)48-80%，單位容積蒸發(fa)強度可(ke)達120-180kg/m3，標(biao)準煤耗僅為6-8kg/t。其(qi)技(ji)術(shu)先進、運行(xing)參(can)數(shu)合理(li)，操(cao)作(zuo)簡單可(ke)行(xing)，廣泛應用于各個行(xing)業(ye)的礦渣、粘土、煤。
產品結(jie)構
三筒(tong)(tong)(tong)烘(hong)(hong)干機是(shi)通過(guo)對單(dan)(dan)筒(tong)(tong)(tong)烘(hong)(hong)干機的單(dan)(dan)筒(tong)(tong)(tong)體(ti)(ti)改為套疊在一起的三筒(tong)(tong)(tong)，以縮短(duan)烘(hong)(hong)干機體(ti)(ti)的外形尺寸(cun)。該機工作時，物料和(he)熱(re)氣流依次進(jin)入內至外筒(tong)(tong)(tong)體(ti)(ti)，在機體(ti)(ti)Z形往復(fu)折流后，充分利用(yong)熱(re)能烘(hong)(hong)干物料后再卸出。
烘干機筒體(ti)(ti)部分(fen)由三個同軸水平(ping)放置(zhi)的(de)內(nei)、中、外筒套(tao)疊組成(cheng)，這(zhe)就使筒體(ti)(ti)的(de)截面得到充分(fen)的(de)利用。其筒體(ti)(ti)外形總(zong)長度約為(wei)與之相(xiang)當的(de)單筒的(de)30-35%。從而大幅(fu)度地減少占地面積(ji)(ji)和廠房(fang)建筑面積(ji)(ji)。
該(gai)機的支承(cheng)裝置(zhi)，是在(zai)外筒上輪(lun)(lun)帶(dai)與托(tuo)(tuo)輪(lun)(lun)支承(cheng)，由(you)電(dian)機直接帶(dai)動托(tuo)(tuo)輪(lun)(lun)。通(tong)過托(tuo)(tuo)輪(lun)(lun)與輪(lun)(lun)帶(dai)摩擦，使筒體轉動。該(gai)機總體結(jie)構緊湊、合理、簡單(dan)，為(wei)便于磨損(sun)件的檢修更換(huan)，在(zai)中(zhong)間(jian)設(she)計成軸向剖分式，用螺栓固定連(lian)接。
工作原(yuan)理
物(wu)(wu)料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝置進(jin)(jin)入回轉滾(gun)筒(tong)(tong)的(de)(de)(de)內(nei)(nei)層(ceng)(ceng),實現順流(liu)(liu)烘干(gan),物(wu)(wu)料(liao)(liao)(liao)在內(nei)(nei)層(ceng)(ceng)的(de)(de)(de)抄(chao)板下不斷抄(chao)起、散(san)落呈(cheng)螺旋(xuan)行(xing)(xing)(xing)進(jin)(jin)式(shi)實現熱(re)交換，物(wu)(wu)料(liao)(liao)(liao)移動(dong)至(zhi)內(nei)(nei)層(ceng)(ceng)的(de)(de)(de)另一端(duan)(duan)進(jin)(jin)入中(zhong)(zhong)(zhong)層(ceng)(ceng)，進(jin)(jin)行(xing)(xing)(xing)逆流(liu)(liu)烘干(gan)，物(wu)(wu)料(liao)(liao)(liao)在中(zhong)(zhong)(zhong)層(ceng)(ceng)不斷地(di)被反復(fu)揚進(jin)(jin)，呈(cheng)進(jin)(jin)兩步退一步的(de)(de)(de)行(xing)(xing)(xing)進(jin)(jin)方(fang)(fang)式(shi)，物(wu)(wu)料(liao)(liao)(liao)在中(zhong)(zhong)(zhong)層(ceng)(ceng)既充分吸(xi)收內(nei)(nei)層(ceng)(ceng)滾(gun)筒(tong)(tong)散(san)發的(de)(de)(de)熱(re)量，又吸(xi)收中(zhong)(zhong)(zhong)層(ceng)(ceng)滾(gun)筒(tong)(tong)的(de)(de)(de)熱(re)量，同時(shi)又延長了干(gan)燥(zao)(zao)時(shi)間，物(wu)(wu)料(liao)(liao)(liao)在此達到干(gan)燥(zao)(zao)狀態。物(wu)(wu)料(liao)(liao)(liao)行(xing)(xing)(xing)至(zhi)中(zhong)(zhong)(zhong)層(ceng)(ceng)另一端(duan)(duan)而落入外層(ceng)(ceng)，物(wu)(wu)料(liao)(liao)(liao)在外層(ceng)(ceng)滾(gun)筒(tong)(tong)內(nei)(nei)呈(cheng)矩形多回路(lu)方(fang)(fang)式(shi)行(xing)(xing)(xing)進(jin)(jin)，達到干(gan)燥(zao)(zao)效果(guo)的(de)(de)(de)物(wu)(wu)料(liao)(liao)(liao)在熱(re)風作(zuo)用下快速行(xing)(xing)(xing)進(jin)(jin)排(pai)出滾(gun)筒(tong)(tong)，沒有達到干(gan)燥(zao)(zao)效果(guo)的(de)(de)(de)濕(shi)物(wu)(wu)料(liao)(liao)(liao)因自重而不能快速行(xing)(xing)(xing)進(jin)(jin)，物(wu)(wu)料(liao)(liao)(liao)在此矩形抄(chao)板內(nei)(nei)進(jin)(jin)行(xing)(xing)(xing)充分干(gan)燥(zao)(zao)，由此完成干(gan)燥(zao)(zao)目的(de)(de)(de)。
