產品概(gai)況
回轉式(shi)三筒烘(hong)干機(ji)改(gai)進(jin)原(yuan)單(dan)(dan)(dan)筒烘(hong)干機(ji)內(nei)部結(jie)構，增加(jia)入機(ji)前濕(shi)料的(de)預烘(hong)干和延長濕(shi)料在機(ji)內(nei)烘(hong)干時間，再(zai)加(jia)上密(mi)封(feng)、保溫以及合(he)(he)理的(de)配套措施(shi)，使烘(hong)干機(ji)生產(chan)能力與原(yuan)單(dan)(dan)(dan)筒式(shi)烘(hong)干機(ji)相比，提高48-80%，單(dan)(dan)(dan)位(wei)容(rong)積蒸發強度可達120-180kg/m3，標準(zhun)煤(mei)耗僅為(wei)6-8kg/t。其技術(shu)先(xian)進(jin)、運(yun)行參數合(he)(he)理，操作簡單(dan)(dan)(dan)可行，廣泛(fan)應用于各個行業的(de)礦渣、粘土、煤(mei)。
產品結構
三筒烘(hong)干(gan)機(ji)是(shi)通過對(dui)單筒烘(hong)干(gan)機(ji)的單筒體改(gai)為套疊在一起的三筒，以縮短烘(hong)干(gan)機(ji)體的外(wai)形(xing)尺寸(cun)。該(gai)機(ji)工(gong)作時，物(wu)料(liao)和熱氣(qi)流(liu)依(yi)次進入內(nei)至外(wai)筒體，在機(ji)體Z形(xing)往復折流(liu)后，充分(fen)利用(yong)熱能烘(hong)干(gan)物(wu)料(liao)后再卸出。
烘干機筒(tong)體部分由三個同軸水平放置的內、中、外筒(tong)套疊組成，這(zhe)就使筒(tong)體的截面得到充分的利用(yong)。其筒(tong)體外形總(zong)長度約為與之(zhi)相當的單筒(tong)的30-35%。從而大幅度地減(jian)少占(zhan)地面積和廠房(fang)建(jian)筑面積。
該機(ji)的支(zhi)承(cheng)(cheng)裝置(zhi)，是在外筒上(shang)輪(lun)帶(dai)與(yu)托輪(lun)支(zhi)承(cheng)(cheng)，由電(dian)機(ji)直接(jie)(jie)帶(dai)動(dong)托輪(lun)。通過(guo)托輪(lun)與(yu)輪(lun)帶(dai)摩(mo)擦(ca)，使筒體轉(zhuan)動(dong)。該機(ji)總體結構(gou)緊湊、合理、簡單，為便于磨損件(jian)的檢修更換，在中間設計成軸向剖分式，用螺栓固定連接(jie)(jie)。
工作原理
物料(liao)(liao)由(you)供(gong)料(liao)(liao)裝置進(jin)(jin)入(ru)回轉(zhuan)滾(gun)筒(tong)(tong)(tong)的(de)內層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng),實(shi)現順流烘干,物料(liao)(liao)在內層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)的(de)抄板下(xia)不斷抄起、散落呈(cheng)螺旋行(xing)(xing)進(jin)(jin)式實(shi)現熱交換，物料(liao)(liao)移(yi)動至(zhi)內層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)的(de)另(ling)(ling)一(yi)端進(jin)(jin)入(ru)中層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)，進(jin)(jin)行(xing)(xing)逆流烘干，物料(liao)(liao)在中層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)不斷地被反復(fu)揚進(jin)(jin)，呈(cheng)進(jin)(jin)兩步(bu)退一(yi)步(bu)的(de)行(xing)(xing)進(jin)(jin)方式，物料(liao)(liao)在中層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)既充分吸(xi)收內層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)(tong)散發的(de)熱量(liang)，又吸(xi)收中層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)(tong)的(de)熱量(liang)，同時(shi)又延(yan)長了干燥時(shi)間，物料(liao)(liao)在此(ci)達到干燥狀態。物料(liao)(liao)行(xing)(xing)至(zhi)中層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)另(ling)(ling)一(yi)端而落入(ru)外層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)，物料(liao)(liao)在外層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)滾(gun)筒(tong)(tong)(tong)內呈(cheng)矩(ju)(ju)形(xing)多回路方式行(xing)(xing)進(jin)(jin)，達到干燥效(xiao)(xiao)果(guo)的(de)物料(liao)(liao)在熱風作用下(xia)快(kuai)速(su)行(xing)(xing)進(jin)(jin)排(pai)出滾(gun)筒(tong)(tong)(tong)，沒(mei)有達到干燥效(xiao)(xiao)果(guo)的(de)濕物料(liao)(liao)因自重(zhong)而不能快(kuai)速(su)行(xing)(xing)進(jin)(jin)，物料(liao)(liao)在此(ci)矩(ju)(ju)形(xing)抄板內進(jin)(jin)行(xing)(xing)充分干燥，由(you)此(ci)完成干燥目的(de)。
