產品概況
回轉式(shi)三筒烘(hong)(hong)干(gan)(gan)(gan)機(ji)改進(jin)原單(dan)(dan)筒烘(hong)(hong)干(gan)(gan)(gan)機(ji)內部結構，增加入機(ji)前濕料的(de)預烘(hong)(hong)干(gan)(gan)(gan)和延(yan)長濕料在機(ji)內烘(hong)(hong)干(gan)(gan)(gan)時間，再(zai)加上密封、保溫(wen)以及合(he)理的(de)配套措施，使烘(hong)(hong)干(gan)(gan)(gan)機(ji)生產能力與(yu)原單(dan)(dan)筒式(shi)烘(hong)(hong)干(gan)(gan)(gan)機(ji)相比，提(ti)高(gao)48-80%，單(dan)(dan)位容積蒸(zheng)發強(qiang)度可達(da)120-180kg/m3，標準煤耗(hao)僅為(wei)6-8kg/t。其技術先進(jin)、運行參(can)數合(he)理，操作簡單(dan)(dan)可行，廣泛應用于各個行業(ye)的(de)礦渣、粘(zhan)土、煤。
產品結構
三(san)筒(tong)(tong)(tong)烘干(gan)機(ji)是通過(guo)對單筒(tong)(tong)(tong)烘干(gan)機(ji)的(de)單筒(tong)(tong)(tong)體改為套疊在一起的(de)三(san)筒(tong)(tong)(tong)，以(yi)縮短烘干(gan)機(ji)體的(de)外形尺寸。該機(ji)工作時(shi)，物(wu)料和熱(re)氣流(liu)依次進(jin)入內至(zhi)外筒(tong)(tong)(tong)體，在機(ji)體Z形往復折流(liu)后(hou)，充分利用熱(re)能烘干(gan)物(wu)料后(hou)再卸出。
烘干機筒(tong)體(ti)部分由(you)三個同軸水平放置(zhi)的(de)(de)內、中、外(wai)筒(tong)套疊組成，這就使(shi)筒(tong)體(ti)的(de)(de)截(jie)面得到充分的(de)(de)利(li)用。其筒(tong)體(ti)外(wai)形總(zong)長(chang)度(du)(du)約為與之相當的(de)(de)單筒(tong)的(de)(de)30-35%。從而大幅度(du)(du)地(di)減少占(zhan)地(di)面積和(he)廠(chang)房(fang)建(jian)筑面積。
該機的支承裝置(zhi)，是在(zai)外筒上輪(lun)帶與托(tuo)輪(lun)支承，由(you)電機直接(jie)帶動(dong)托(tuo)輪(lun)。通過托(tuo)輪(lun)與輪(lun)帶摩(mo)擦，使(shi)筒體轉動(dong)。該機總體結構緊湊、合理、簡單，為(wei)便于磨損(sun)件的檢修更換，在(zai)中間設計成軸向剖分式，用(yong)螺栓固定連接(jie)。
工作原理
物(wu)(wu)(wu)料(liao)(liao)由供料(liao)(liao)裝置(zhi)進(jin)(jin)入回轉滾(gun)筒(tong)(tong)(tong)的內(nei)(nei)層(ceng),實(shi)現(xian)(xian)順流烘干(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)內(nei)(nei)層(ceng)的抄(chao)板(ban)下不(bu)斷抄(chao)起、散落呈螺(luo)旋行(xing)進(jin)(jin)式實(shi)現(xian)(xian)熱(re)(re)(re)(re)交換，物(wu)(wu)(wu)料(liao)(liao)移動(dong)至內(nei)(nei)層(ceng)的另(ling)一端(duan)進(jin)(jin)入中層(ceng)，進(jin)(jin)行(xing)逆流烘干(gan)，物(wu)(wu)(wu)料(liao)(liao)在(zai)中層(ceng)不(bu)斷地被(bei)反(fan)復(fu)揚進(jin)(jin)，呈進(jin)(jin)兩步退一步的行(xing)進(jin)(jin)方(fang)式，物(wu)(wu)(wu)料(liao)(liao)在(zai)中層(ceng)既充分(fen)吸收(shou)內(nei)(nei)層(ceng)滾(gun)筒(tong)(tong)(tong)散發的熱(re)(re)(re)(re)量(liang)，又吸收(shou)中層(ceng)滾(gun)筒(tong)(tong)(tong)的熱(re)(re)(re)(re)量(liang)，同時(shi)又延長了干(gan)燥(zao)時(shi)間(jian)，物(wu)(wu)(wu)料(liao)(liao)在(zai)此(ci)達到(dao)干(gan)燥(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)行(xing)至中層(ceng)另(ling)一端(duan)而落入外層(ceng)，物(wu)(wu)(wu)料(liao)(liao)在(zai)外層(ceng)滾(gun)筒(tong)(tong)(tong)內(nei)(nei)呈矩(ju)形(xing)多回路方(fang)式行(xing)進(jin)(jin)，達到(dao)干(gan)燥(zao)效(xiao)果(guo)的物(wu)(wu)(wu)料(liao)(liao)在(zai)熱(re)(re)(re)(re)風作用下快速行(xing)進(jin)(jin)排出滾(gun)筒(tong)(tong)(tong)，沒有(you)達到(dao)干(gan)燥(zao)效(xiao)果(guo)的濕物(wu)(wu)(wu)料(liao)(liao)因(yin)自重而不(bu)能快速行(xing)進(jin)(jin)，物(wu)(wu)(wu)料(liao)(liao)在(zai)此(ci)矩(ju)形(xing)抄(chao)板(ban)內(nei)(nei)進(jin)(jin)行(xing)充分(fen)干(gan)燥(zao)，由此(ci)完(wan)成(cheng)干(gan)燥(zao)目的。
