產品概況
回轉式(shi)三筒烘(hong)干機(ji)(ji)改(gai)進原(yuan)單筒烘(hong)干機(ji)(ji)內部結(jie)構，增(zeng)加入機(ji)(ji)前濕料(liao)的預烘(hong)干和延長濕料(liao)在機(ji)(ji)內烘(hong)干時間，再加上(shang)密封、保溫以及合理的配套措施，使烘(hong)干機(ji)(ji)生產能力與原(yuan)單筒式(shi)烘(hong)干機(ji)(ji)相比，提高48-80%，單位容積蒸發強度可達120-180kg/m3，標準煤(mei)(mei)耗(hao)僅(jin)為6-8kg/t。其技(ji)術先進、運行(xing)參數合理，操(cao)作簡(jian)單可行(xing)，廣泛應用于各(ge)個行(xing)業的礦渣、粘(zhan)土、煤(mei)(mei)。
產品結構
三(san)筒(tong)(tong)烘(hong)干(gan)(gan)機是通過對(dui)單(dan)筒(tong)(tong)烘(hong)干(gan)(gan)機的單(dan)筒(tong)(tong)體(ti)(ti)改為套(tao)疊在一起的三(san)筒(tong)(tong)，以縮短烘(hong)干(gan)(gan)機體(ti)(ti)的外(wai)形尺寸。該機工(gong)作時，物(wu)料和(he)熱(re)(re)氣流依次進入內至外(wai)筒(tong)(tong)體(ti)(ti)，在機體(ti)(ti)Z形往復折流后，充分利(li)用熱(re)(re)能烘(hong)干(gan)(gan)物(wu)料后再卸出。
烘(hong)干機筒(tong)體部分由三個同軸水平放(fang)置(zhi)的(de)內、中、外筒(tong)套疊組成，這就使(shi)筒(tong)體的(de)截(jie)面(mian)得到充分的(de)利用。其筒(tong)體外形總長度約為與(yu)之相當的(de)單(dan)筒(tong)的(de)30-35%。從(cong)而大幅度地減少(shao)占地面(mian)積和廠房建筑面(mian)積。
該機的支(zhi)承裝置，是在外(wai)筒(tong)上輪帶(dai)(dai)與托(tuo)輪支(zhi)承，由電機直接(jie)帶(dai)(dai)動托(tuo)輪。通過托(tuo)輪與輪帶(dai)(dai)摩擦，使筒(tong)體轉動。該機總體結構緊湊、合理、簡單(dan)，為(wei)便(bian)于磨損(sun)件的檢(jian)修(xiu)更換，在中間設計成軸向剖分式，用(yong)螺栓(shuan)固定連(lian)接(jie)。
工(gong)作原理
物(wu)(wu)(wu)料(liao)(liao)由(you)供料(liao)(liao)裝(zhuang)置(zhi)進(jin)(jin)(jin)(jin)入(ru)(ru)回轉(zhuan)滾(gun)筒的內層(ceng)(ceng)(ceng),實現順流(liu)烘干(gan)(gan)(gan),物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)內層(ceng)(ceng)(ceng)的抄(chao)板下(xia)不(bu)斷抄(chao)起(qi)、散落呈螺旋行(xing)(xing)(xing)進(jin)(jin)(jin)(jin)式實現熱(re)交(jiao)換，物(wu)(wu)(wu)料(liao)(liao)移(yi)動至內層(ceng)(ceng)(ceng)的另一端(duan)進(jin)(jin)(jin)(jin)入(ru)(ru)中(zhong)(zhong)層(ceng)(ceng)(ceng)，進(jin)(jin)(jin)(jin)行(xing)(xing)(xing)逆(ni)流(liu)烘干(gan)(gan)(gan)，物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)不(bu)斷地被(bei)反復(fu)揚進(jin)(jin)(jin)(jin)，呈進(jin)(jin)(jin)(jin)兩步(bu)退一步(bu)的行(xing)(xing)(xing)進(jin)(jin)(jin)(jin)方式，物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)既充分(fen)吸(xi)收(shou)內層(ceng)(ceng)(ceng)滾(gun)筒散發(fa)的熱(re)量(liang)，又吸(xi)收(shou)中(zhong)(zhong)層(ceng)(ceng)(ceng)滾(gun)筒的熱(re)量(liang)，同時又延長了干(gan)(gan)(gan)燥(zao)(zao)時間，物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)此(ci)(ci)達(da)到干(gan)(gan)(gan)燥(zao)(zao)狀態。物(wu)(wu)(wu)料(liao)(liao)行(xing)(xing)(xing)至中(zhong)(zhong)層(ceng)(ceng)(ceng)另一端(duan)而落入(ru)(ru)外(wai)層(ceng)(ceng)(ceng)，物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)外(wai)層(ceng)(ceng)(ceng)滾(gun)筒內呈矩形多(duo)回路方式行(xing)(xing)(xing)進(jin)(jin)(jin)(jin)，達(da)到干(gan)(gan)(gan)燥(zao)(zao)效果(guo)的物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)熱(re)風作用(yong)下(xia)快速行(xing)(xing)(xing)進(jin)(jin)(jin)(jin)排出滾(gun)筒，沒有達(da)到干(gan)(gan)(gan)燥(zao)(zao)效果(guo)的濕(shi)物(wu)(wu)(wu)料(liao)(liao)因(yin)自(zi)重而不(bu)能快速行(xing)(xing)(xing)進(jin)(jin)(jin)(jin)，物(wu)(wu)(wu)料(liao)(liao)在(zai)(zai)此(ci)(ci)矩形抄(chao)板內進(jin)(jin)(jin)(jin)行(xing)(xing)(xing)充分(fen)干(gan)(gan)(gan)燥(zao)(zao)，由(you)此(ci)(ci)完成干(gan)(gan)(gan)燥(zao)(zao)目的。
