產品(pin)概況
回轉(zhuan)式三筒(tong)烘(hong)(hong)(hong)(hong)(hong)干(gan)(gan)機(ji)(ji)改(gai)進原(yuan)單(dan)筒(tong)烘(hong)(hong)(hong)(hong)(hong)干(gan)(gan)機(ji)(ji)內部結構，增加入機(ji)(ji)前濕料的預烘(hong)(hong)(hong)(hong)(hong)干(gan)(gan)和延長濕料在機(ji)(ji)內烘(hong)(hong)(hong)(hong)(hong)干(gan)(gan)時(shi)間，再加上密封、保溫以及合(he)理的配套措施(shi)，使烘(hong)(hong)(hong)(hong)(hong)干(gan)(gan)機(ji)(ji)生產能(neng)力與原(yuan)單(dan)筒(tong)式烘(hong)(hong)(hong)(hong)(hong)干(gan)(gan)機(ji)(ji)相比，提(ti)高48-80%，單(dan)位容積蒸發強度可(ke)達120-180kg/m3，標準煤(mei)耗僅(jin)為6-8kg/t。其(qi)技術先(xian)進、運(yun)行(xing)參數合(he)理，操(cao)作簡單(dan)可(ke)行(xing)，廣泛應(ying)用于各個行(xing)業(ye)的礦渣、粘土、煤(mei)。
產品結構(gou)
三筒(tong)(tong)烘(hong)(hong)(hong)干機是通過對(dui)單筒(tong)(tong)烘(hong)(hong)(hong)干機的單筒(tong)(tong)體(ti)改為套疊在一起的三筒(tong)(tong)，以縮短烘(hong)(hong)(hong)干機體(ti)的外形尺寸。該機工作(zuo)時(shi)，物料和熱氣流依(yi)次進入內至外筒(tong)(tong)體(ti)，在機體(ti)Z形往(wang)復折流后(hou)，充(chong)分利用熱能烘(hong)(hong)(hong)干物料后(hou)再卸出。
烘干機筒(tong)體(ti)部分由(you)三(san)個(ge)同軸水平放置的(de)內、中、外筒(tong)套疊組成，這(zhe)就使筒(tong)體(ti)的(de)截(jie)面得到充分的(de)利用。其筒(tong)體(ti)外形(xing)總長度約為與之相(xiang)當的(de)單筒(tong)的(de)30-35%。從而(er)大幅度地減(jian)少占地面積和廠房建(jian)筑(zhu)面積。
該(gai)機(ji)(ji)的支承(cheng)裝置，是在外(wai)筒上輪帶與(yu)托(tuo)(tuo)輪支承(cheng)，由電機(ji)(ji)直接(jie)帶動(dong)托(tuo)(tuo)輪。通(tong)過托(tuo)(tuo)輪與(yu)輪帶摩(mo)擦，使筒體轉(zhuan)動(dong)。該(gai)機(ji)(ji)總體結構(gou)緊湊、合(he)理(li)、簡單(dan)，為便于磨損件的檢修(xiu)更換，在中間設(she)計成(cheng)軸(zhou)向剖分(fen)式，用螺(luo)栓固定連(lian)接(jie)。
工作原(yuan)理
物(wu)(wu)料(liao)由供(gong)料(liao)裝置進(jin)入(ru)回轉(zhuan)滾(gun)筒的(de)(de)(de)(de)內(nei)(nei)層(ceng)(ceng),實現(xian)順流烘干(gan),物(wu)(wu)料(liao)在(zai)內(nei)(nei)層(ceng)(ceng)的(de)(de)(de)(de)抄(chao)板下(xia)不斷(duan)抄(chao)起、散(san)落(luo)呈(cheng)螺旋(xuan)行(xing)(xing)進(jin)式實現(xian)熱(re)交換，物(wu)(wu)料(liao)移動至(zhi)內(nei)(nei)層(ceng)(ceng)的(de)(de)(de)(de)另一端(duan)進(jin)入(ru)中(zhong)層(ceng)(ceng)，進(jin)行(xing)(xing)逆流烘干(gan)，物(wu)(wu)料(liao)在(zai)中(zhong)層(ceng)(ceng)不斷(duan)地被反(fan)復揚進(jin)，呈(cheng)進(jin)兩步(bu)退一步(bu)的(de)(de)(de)(de)行(xing)(xing)進(jin)方式，物(wu)(wu)料(liao)在(zai)中(zhong)層(ceng)(ceng)既充分吸(xi)收內(nei)(nei)層(ceng)(ceng)滾(gun)筒散(san)發的(de)(de)(de)(de)熱(re)量(liang)，又吸(xi)收中(zhong)層(ceng)(ceng)滾(gun)筒的(de)(de)(de)(de)熱(re)量(liang)，同時又延長了干(gan)燥時間(jian)，物(wu)(wu)料(liao)在(zai)此(ci)達(da)到干(gan)燥狀態。物(wu)(wu)料(liao)行(xing)(xing)至(zhi)中(zhong)層(ceng)(ceng)另一端(duan)而(er)落(luo)入(ru)外層(ceng)(ceng)，物(wu)(wu)料(liao)在(zai)外層(ceng)(ceng)滾(gun)筒內(nei)(nei)呈(cheng)矩形(xing)多回路方式行(xing)(xing)進(jin)，達(da)到干(gan)燥效果的(de)(de)(de)(de)物(wu)(wu)料(liao)在(zai)熱(re)風(feng)作用(yong)下(xia)快(kuai)速(su)行(xing)(xing)進(jin)排出(chu)滾(gun)筒，沒有達(da)到干(gan)燥效果的(de)(de)(de)(de)濕物(wu)(wu)料(liao)因(yin)自(zi)重而(er)不能快(kuai)速(su)行(xing)(xing)進(jin)，物(wu)(wu)料(liao)在(zai)此(ci)矩形(xing)抄(chao)板內(nei)(nei)進(jin)行(xing)(xing)充分干(gan)燥，由此(ci)完成干(gan)燥目(mu)的(de)(de)(de)(de)。
