產品概(gai)況
回轉式三(san)筒(tong)烘干機(ji)(ji)改進原(yuan)單(dan)(dan)筒(tong)烘干機(ji)(ji)內部結構，增(zeng)加入機(ji)(ji)前濕料的預烘干和延(yan)長濕料在機(ji)(ji)內烘干時(shi)間，再(zai)加上(shang)密(mi)封(feng)、保溫以及合(he)理的配套措(cuo)施，使烘干機(ji)(ji)生產能力與原(yuan)單(dan)(dan)筒(tong)式烘干機(ji)(ji)相比，提高48-80%，單(dan)(dan)位容積蒸發強度可達120-180kg/m3，標準煤耗僅(jin)為6-8kg/t。其技術(shu)先進、運行(xing)參(can)數合(he)理，操作簡(jian)單(dan)(dan)可行(xing)，廣(guang)泛應(ying)用于各個(ge)行(xing)業的礦渣、粘(zhan)土、煤。
產品結構
三筒烘(hong)干(gan)機(ji)是(shi)通(tong)過對單(dan)筒烘(hong)干(gan)機(ji)的(de)單(dan)筒體改為套疊在一起的(de)三筒，以(yi)縮短烘(hong)干(gan)機(ji)體的(de)外(wai)形尺寸。該機(ji)工作時，物料和熱(re)氣流依次進入(ru)內至外(wai)筒體，在機(ji)體Z形往復(fu)折流后，充分利用熱(re)能烘(hong)干(gan)物料后再卸出。
烘(hong)干機筒(tong)體(ti)部分由三個(ge)同軸水平放置的內、中、外(wai)筒(tong)套疊組成，這就使筒(tong)體(ti)的截面(mian)得到充(chong)分的利(li)用(yong)。其(qi)筒(tong)體(ti)外(wai)形總長度約為與(yu)之相當的單筒(tong)的30-35%。從(cong)而大(da)幅度地減少占(zhan)地面(mian)積和廠房建筑面(mian)積。
該機(ji)(ji)的支承(cheng)裝置，是在外筒(tong)上輪(lun)帶與托輪(lun)支承(cheng)，由電機(ji)(ji)直接帶動托輪(lun)。通(tong)過托輪(lun)與輪(lun)帶摩擦，使筒(tong)體轉動。該機(ji)(ji)總體結構緊湊、合理、簡(jian)單，為便于磨損件(jian)的檢修更換，在中間設計成軸向(xiang)剖分式，用螺栓固(gu)定連接。
工作(zuo)原理
物(wu)料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝(zhuang)置(zhi)進(jin)(jin)(jin)(jin)入(ru)回轉滾(gun)筒的內層(ceng)(ceng)(ceng),實現順流(liu)(liu)烘(hong)(hong)干,物(wu)料(liao)(liao)(liao)在(zai)內層(ceng)(ceng)(ceng)的抄(chao)板下不(bu)(bu)斷(duan)抄(chao)起、散(san)落呈(cheng)螺旋行(xing)(xing)進(jin)(jin)(jin)(jin)式實現熱(re)交換，物(wu)料(liao)(liao)(liao)移動至內層(ceng)(ceng)(ceng)的另(ling)一端進(jin)(jin)(jin)(jin)入(ru)中層(ceng)(ceng)(ceng)，進(jin)(jin)(jin)(jin)行(xing)(xing)逆流(liu)(liu)烘(hong)(hong)干，物(wu)料(liao)(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)不(bu)(bu)斷(duan)地被反復(fu)揚進(jin)(jin)(jin)(jin)，呈(cheng)進(jin)(jin)(jin)(jin)兩步退一步的行(xing)(xing)進(jin)(jin)(jin)(jin)方式，物(wu)料(liao)(liao)(liao)在(zai)中層(ceng)(ceng)(ceng)既充(chong)分吸收內層(ceng)(ceng)(ceng)滾(gun)筒散(san)發的熱(re)量，又吸收中層(ceng)(ceng)(ceng)滾(gun)筒的熱(re)量，同時(shi)又延長了干燥(zao)(zao)(zao)時(shi)間，物(wu)料(liao)(liao)(liao)在(zai)此達到(dao)干燥(zao)(zao)(zao)狀態。物(wu)料(liao)(liao)(liao)行(xing)(xing)至中層(ceng)(ceng)(ceng)另(ling)一端而落入(ru)外層(ceng)(ceng)(ceng)，物(wu)料(liao)(liao)(liao)在(zai)外層(ceng)(ceng)(ceng)滾(gun)筒內呈(cheng)矩(ju)形多回路方式行(xing)(xing)進(jin)(jin)(jin)(jin)，達到(dao)干燥(zao)(zao)(zao)效果(guo)的物(wu)料(liao)(liao)(liao)在(zai)熱(re)風作(zuo)用下快速行(xing)(xing)進(jin)(jin)(jin)(jin)排出滾(gun)筒，沒有達到(dao)干燥(zao)(zao)(zao)效果(guo)的濕(shi)物(wu)料(liao)(liao)(liao)因(yin)自重而不(bu)(bu)能快速行(xing)(xing)進(jin)(jin)(jin)(jin)，物(wu)料(liao)(liao)(liao)在(zai)此矩(ju)形抄(chao)板內進(jin)(jin)(jin)(jin)行(xing)(xing)充(chong)分干燥(zao)(zao)(zao)，由此完成干燥(zao)(zao)(zao)目的。
