產品概況
回(hui)轉式三(san)筒(tong)(tong)烘(hong)(hong)干機(ji)(ji)改進原(yuan)單(dan)筒(tong)(tong)烘(hong)(hong)干機(ji)(ji)內部結構，增加入機(ji)(ji)前(qian)濕料的(de)預烘(hong)(hong)干和(he)延長濕料在(zai)機(ji)(ji)內烘(hong)(hong)干時間，再加上密封、保溫(wen)以及(ji)合(he)理的(de)配套措(cuo)施，使烘(hong)(hong)干機(ji)(ji)生產能力與原(yuan)單(dan)筒(tong)(tong)式烘(hong)(hong)干機(ji)(ji)相(xiang)比，提(ti)高48-80%，單(dan)位容積(ji)蒸發強度(du)可達120-180kg/m3，標準煤耗僅為6-8kg/t。其技術(shu)先(xian)進、運行(xing)參數合(he)理，操(cao)作簡單(dan)可行(xing)，廣泛應(ying)用于各(ge)個(ge)行(xing)業(ye)的(de)礦渣、粘土、煤。
產(chan)品結構
三(san)筒(tong)(tong)(tong)烘(hong)(hong)干(gan)機是通過對單(dan)筒(tong)(tong)(tong)烘(hong)(hong)干(gan)機的單(dan)筒(tong)(tong)(tong)體(ti)改為套疊在(zai)一起的三(san)筒(tong)(tong)(tong)，以縮短烘(hong)(hong)干(gan)機體(ti)的外(wai)形(xing)尺寸(cun)。該(gai)機工作時(shi)，物(wu)料(liao)和熱(re)氣流(liu)依次進入內(nei)至外(wai)筒(tong)(tong)(tong)體(ti)，在(zai)機體(ti)Z形(xing)往復折流(liu)后(hou)，充分利(li)用熱(re)能烘(hong)(hong)干(gan)物(wu)料(liao)后(hou)再卸(xie)出。
烘干機筒(tong)體部分由三個同軸水(shui)平放置的(de)(de)(de)內(nei)、中、外筒(tong)套疊組成，這(zhe)就使筒(tong)體的(de)(de)(de)截面(mian)得到充分的(de)(de)(de)利用(yong)。其筒(tong)體外形總長(chang)度約為與(yu)之相當的(de)(de)(de)單筒(tong)的(de)(de)(de)30-35%。從而大(da)幅度地減(jian)少占地面(mian)積和廠房建筑面(mian)積。
該機的支承(cheng)(cheng)裝置，是在外筒(tong)上輪(lun)(lun)帶與托輪(lun)(lun)支承(cheng)(cheng)，由電機直接帶動(dong)托輪(lun)(lun)。通過托輪(lun)(lun)與輪(lun)(lun)帶摩擦，使筒(tong)體(ti)轉動(dong)。該機總(zong)體(ti)結構緊(jin)湊(cou)、合理(li)、簡單(dan)，為便于磨損件的檢修更換，在中間設計(ji)成軸向剖分式，用螺栓固定連接。
工作原(yuan)理
物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)由(you)供(gong)料(liao)(liao)(liao)(liao)裝置進(jin)(jin)入回(hui)轉滾(gun)筒的內層(ceng)(ceng),實現順(shun)流烘干(gan)(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)內層(ceng)(ceng)的抄板下(xia)不斷抄起、散落呈螺旋行(xing)進(jin)(jin)式(shi)實現熱交換，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)移動至內層(ceng)(ceng)的另一端(duan)進(jin)(jin)入中層(ceng)(ceng)，進(jin)(jin)行(xing)逆(ni)流烘干(gan)(gan)(gan)，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)中層(ceng)(ceng)不斷地(di)被(bei)反復(fu)揚進(jin)(jin)，呈進(jin)(jin)兩步退(tui)一步的行(xing)進(jin)(jin)方式(shi)，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)中層(ceng)(ceng)既充分(fen)吸收內層(ceng)(ceng)滾(gun)筒散發的熱量(liang)(liang)，又吸收中層(ceng)(ceng)滾(gun)筒的熱量(liang)(liang)，同時(shi)又延(yan)長(chang)了干(gan)(gan)(gan)燥(zao)(zao)(zao)時(shi)間，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)此達到(dao)干(gan)(gan)(gan)燥(zao)(zao)(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)行(xing)至中層(ceng)(ceng)另一端(duan)而落入外(wai)(wai)層(ceng)(ceng)，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)外(wai)(wai)層(ceng)(ceng)滾(gun)筒內呈矩形多回(hui)路方式(shi)行(xing)進(jin)(jin)，達到(dao)干(gan)(gan)(gan)燥(zao)(zao)(zao)效(xiao)果的物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)熱風作用(yong)下(xia)快(kuai)速行(xing)進(jin)(jin)排出(chu)滾(gun)筒，沒有(you)達到(dao)干(gan)(gan)(gan)燥(zao)(zao)(zao)效(xiao)果的濕物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)因自重(zhong)而不能快(kuai)速行(xing)進(jin)(jin)，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)此矩形抄板內進(jin)(jin)行(xing)充分(fen)干(gan)(gan)(gan)燥(zao)(zao)(zao)，由(you)此完成干(gan)(gan)(gan)燥(zao)(zao)(zao)目的。
