產品概況
回轉式(shi)三筒(tong)烘(hong)(hong)干機改進(jin)原單筒(tong)烘(hong)(hong)干機內(nei)部結構，增(zeng)加(jia)入機前濕料(liao)的預(yu)烘(hong)(hong)干和延長濕料(liao)在機內(nei)烘(hong)(hong)干時間，再加(jia)上(shang)密封(feng)、保溫以及合(he)理(li)的配套措施，使烘(hong)(hong)干機生(sheng)產能力(li)與原單筒(tong)式(shi)烘(hong)(hong)干機相比(bi)，提高48-80%，單位(wei)容積(ji)蒸發(fa)強(qiang)度可達120-180kg/m3，標準煤耗僅為(wei)6-8kg/t。其技術先進(jin)、運行(xing)(xing)參數合(he)理(li)，操作簡單可行(xing)(xing)，廣泛應用于各(ge)個行(xing)(xing)業的礦(kuang)渣、粘(zhan)土、煤。
產品結(jie)構
三筒(tong)(tong)(tong)(tong)烘(hong)干(gan)機是通過(guo)對單筒(tong)(tong)(tong)(tong)烘(hong)干(gan)機的(de)單筒(tong)(tong)(tong)(tong)體改為套(tao)疊在一起的(de)三筒(tong)(tong)(tong)(tong)，以縮短烘(hong)干(gan)機體的(de)外(wai)形(xing)尺寸。該(gai)機工作時，物料(liao)和(he)熱氣流依次進入內至外(wai)筒(tong)(tong)(tong)(tong)體，在機體Z形(xing)往復折流后(hou)，充分利用熱能烘(hong)干(gan)物料(liao)后(hou)再卸出。
烘干(gan)機筒(tong)(tong)體部分由(you)三個同軸水平放置的(de)內、中、外(wai)筒(tong)(tong)套疊組成，這就使(shi)筒(tong)(tong)體的(de)截面得到充分的(de)利用。其筒(tong)(tong)體外(wai)形總長度(du)約為與(yu)之相(xiang)當的(de)單筒(tong)(tong)的(de)30-35%。從而(er)大幅度(du)地(di)減(jian)少占地(di)面積和廠房(fang)建筑面積。
該機(ji)(ji)的(de)支(zhi)承裝置，是在外筒上輪(lun)(lun)帶與托輪(lun)(lun)支(zhi)承，由(you)電機(ji)(ji)直接帶動托輪(lun)(lun)。通(tong)過托輪(lun)(lun)與輪(lun)(lun)帶摩擦，使筒體(ti)轉動。該機(ji)(ji)總體(ti)結構(gou)緊湊(cou)、合理、簡單，為(wei)便于(yu)磨(mo)損件的(de)檢(jian)修更換，在中間設(she)計(ji)成軸向剖分式，用螺栓(shuan)固定(ding)連接。
工作(zuo)原理
物(wu)(wu)料(liao)(liao)(liao)由(you)供(gong)料(liao)(liao)(liao)裝(zhuang)置進(jin)(jin)入回轉滾(gun)筒的(de)內層(ceng)(ceng)(ceng),實現順流烘干(gan),物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)內層(ceng)(ceng)(ceng)的(de)抄板下(xia)不斷(duan)抄起、散落(luo)呈(cheng)螺旋行(xing)(xing)進(jin)(jin)式(shi)(shi)實現熱(re)交換，物(wu)(wu)料(liao)(liao)(liao)移(yi)動至(zhi)內層(ceng)(ceng)(ceng)的(de)另一(yi)(yi)端(duan)進(jin)(jin)入中(zhong)層(ceng)(ceng)(ceng)，進(jin)(jin)行(xing)(xing)逆流烘干(gan)，物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)不斷(duan)地被(bei)反復揚進(jin)(jin)，呈(cheng)進(jin)(jin)兩步(bu)退(tui)一(yi)(yi)步(bu)的(de)行(xing)(xing)進(jin)(jin)方(fang)式(shi)(shi)，物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)中(zhong)層(ceng)(ceng)(ceng)既充分吸(xi)收內層(ceng)(ceng)(ceng)滾(gun)筒散發的(de)熱(re)量(liang)，又(you)(you)吸(xi)收中(zhong)層(ceng)(ceng)(ceng)滾(gun)筒的(de)熱(re)量(liang)，同時又(you)(you)延(yan)長了干(gan)燥(zao)時間，物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)此(ci)達到(dao)干(gan)燥(zao)狀態。物(wu)(wu)料(liao)(liao)(liao)行(xing)(xing)至(zhi)中(zhong)層(ceng)(ceng)(ceng)另一(yi)(yi)端(duan)而落(luo)入外(wai)層(ceng)(ceng)(ceng)，物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)外(wai)層(ceng)(ceng)(ceng)滾(gun)筒內呈(cheng)矩形多回路方(fang)式(shi)(shi)行(xing)(xing)進(jin)(jin)，達到(dao)干(gan)燥(zao)效果的(de)物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)熱(re)風作(zuo)用下(xia)快速行(xing)(xing)進(jin)(jin)排出滾(gun)筒，沒有達到(dao)干(gan)燥(zao)效果的(de)濕物(wu)(wu)料(liao)(liao)(liao)因自重而不能快速行(xing)(xing)進(jin)(jin)，物(wu)(wu)料(liao)(liao)(liao)在(zai)(zai)此(ci)矩形抄板內進(jin)(jin)行(xing)(xing)充分干(gan)燥(zao)，由(you)此(ci)完成(cheng)干(gan)燥(zao)目的(de)。
