產品概(gai)況
回(hui)轉式(shi)三筒(tong)(tong)烘(hong)干(gan)機(ji)改進(jin)(jin)原(yuan)單筒(tong)(tong)烘(hong)干(gan)機(ji)內部結構(gou)，增加入機(ji)前濕料(liao)的(de)預烘(hong)干(gan)和延長濕料(liao)在機(ji)內烘(hong)干(gan)時間，再加上(shang)密封、保(bao)溫以及合理的(de)配套(tao)措(cuo)施，使烘(hong)干(gan)機(ji)生產能力與原(yuan)單筒(tong)(tong)式(shi)烘(hong)干(gan)機(ji)相比，提高48-80%，單位容積蒸(zheng)發(fa)強(qiang)度(du)可達120-180kg/m3，標準煤耗僅為6-8kg/t。其技術先進(jin)(jin)、運行參數合理，操作(zuo)簡單可行，廣泛(fan)應用于(yu)各個行業的(de)礦渣、粘(zhan)土、煤。
產品結(jie)構
三筒烘干(gan)(gan)(gan)機是通過對單筒烘干(gan)(gan)(gan)機的(de)單筒體(ti)改為套疊(die)在(zai)一起(qi)的(de)三筒，以縮短烘干(gan)(gan)(gan)機體(ti)的(de)外形尺寸。該機工作時，物料(liao)和熱(re)氣流依次進入內(nei)至(zhi)外筒體(ti)，在(zai)機體(ti)Z形往復(fu)折流后(hou)，充分利用熱(re)能烘干(gan)(gan)(gan)物料(liao)后(hou)再卸(xie)出。
烘干機筒(tong)(tong)(tong)體(ti)部分(fen)由(you)三個同軸水平放置的(de)(de)內、中(zhong)、外(wai)筒(tong)(tong)(tong)套疊組成(cheng)，這(zhe)就(jiu)使筒(tong)(tong)(tong)體(ti)的(de)(de)截面得到充分(fen)的(de)(de)利用(yong)。其筒(tong)(tong)(tong)體(ti)外(wai)形總長度約為(wei)與之相當的(de)(de)單筒(tong)(tong)(tong)的(de)(de)30-35%。從而大(da)幅(fu)度地減少占地面積和廠房建筑面積。
該(gai)機(ji)(ji)的支(zhi)承(cheng)裝置，是在外(wai)筒上輪帶(dai)與托(tuo)輪支(zhi)承(cheng)，由電(dian)機(ji)(ji)直接帶(dai)動托(tuo)輪。通過托(tuo)輪與輪帶(dai)摩擦，使筒體(ti)轉動。該(gai)機(ji)(ji)總體(ti)結(jie)構緊湊、合理、簡(jian)單，為便于磨損(sun)件的檢修更換(huan)，在中(zhong)間設計成軸向剖分(fen)式(shi)，用螺栓固(gu)定(ding)連接。
工作(zuo)原理
物(wu)(wu)(wu)料(liao)由供料(liao)裝(zhuang)置(zhi)進(jin)(jin)(jin)(jin)入(ru)(ru)回轉滾(gun)(gun)(gun)筒(tong)(tong)的(de)(de)內層(ceng)(ceng)(ceng)(ceng),實(shi)現(xian)順流(liu)烘干,物(wu)(wu)(wu)料(liao)在(zai)內層(ceng)(ceng)(ceng)(ceng)的(de)(de)抄板下不(bu)斷抄起、散落呈(cheng)螺(luo)旋行(xing)(xing)進(jin)(jin)(jin)(jin)式實(shi)現(xian)熱交(jiao)換(huan)，物(wu)(wu)(wu)料(liao)移動至(zhi)內層(ceng)(ceng)(ceng)(ceng)的(de)(de)另(ling)一(yi)端進(jin)(jin)(jin)(jin)入(ru)(ru)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)，進(jin)(jin)(jin)(jin)行(xing)(xing)逆流(liu)烘干，物(wu)(wu)(wu)料(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)不(bu)斷地被(bei)反復揚進(jin)(jin)(jin)(jin)，呈(cheng)進(jin)(jin)(jin)(jin)兩步(bu)退一(yi)步(bu)的(de)(de)行(xing)(xing)進(jin)(jin)(jin)(jin)方(fang)式，物(wu)(wu)(wu)料(liao)在(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)既充(chong)分吸收(shou)內層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)(tong)散發(fa)的(de)(de)熱量，又吸收(shou)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)(tong)的(de)(de)熱量，同時(shi)(shi)又延長了干燥(zao)時(shi)(shi)間，物(wu)(wu)(wu)料(liao)在(zai)此(ci)達(da)到干燥(zao)狀態。物(wu)(wu)(wu)料(liao)行(xing)(xing)至(zhi)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)另(ling)一(yi)端而(er)落入(ru)(ru)外層(ceng)(ceng)(ceng)(ceng)，物(wu)(wu)(wu)料(liao)在(zai)外層(ceng)(ceng)(ceng)(ceng)滾(gun)(gun)(gun)筒(tong)(tong)內呈(cheng)矩形(xing)多(duo)回路方(fang)式行(xing)(xing)進(jin)(jin)(jin)(jin)，達(da)到干燥(zao)效(xiao)果的(de)(de)物(wu)(wu)(wu)料(liao)在(zai)熱風作用下快速行(xing)(xing)進(jin)(jin)(jin)(jin)排出滾(gun)(gun)(gun)筒(tong)(tong)，沒有達(da)到干燥(zao)效(xiao)果的(de)(de)濕物(wu)(wu)(wu)料(liao)因自重而(er)不(bu)能快速行(xing)(xing)進(jin)(jin)(jin)(jin)，物(wu)(wu)(wu)料(liao)在(zai)此(ci)矩形(xing)抄板內進(jin)(jin)(jin)(jin)行(xing)(xing)充(chong)分干燥(zao)，由此(ci)完(wan)成干燥(zao)目的(de)(de)。
