產品(pin)概況
回轉(zhuan)式(shi)三筒烘(hong)(hong)干(gan)機(ji)(ji)改進原單(dan)(dan)筒烘(hong)(hong)干(gan)機(ji)(ji)內(nei)部結構(gou)，增加入(ru)機(ji)(ji)前濕料的(de)(de)預烘(hong)(hong)干(gan)和延長濕料在機(ji)(ji)內(nei)烘(hong)(hong)干(gan)時間，再加上密封、保溫以(yi)及合理的(de)(de)配套措(cuo)施，使烘(hong)(hong)干(gan)機(ji)(ji)生產能(neng)力與原單(dan)(dan)筒式(shi)烘(hong)(hong)干(gan)機(ji)(ji)相比，提高48-80%，單(dan)(dan)位容積蒸(zheng)發強(qiang)度(du)可(ke)達120-180kg/m3，標準煤耗僅為6-8kg/t。其技術(shu)先進、運行參數(shu)合理，操(cao)作簡單(dan)(dan)可(ke)行，廣泛(fan)應用于各個行業的(de)(de)礦渣、粘土、煤。
產品(pin)結構
三筒烘(hong)干(gan)(gan)機(ji)是通過對(dui)單筒烘(hong)干(gan)(gan)機(ji)的單筒體改為(wei)套疊在一起的三筒，以縮短烘(hong)干(gan)(gan)機(ji)體的外形尺(chi)寸。該(gai)機(ji)工(gong)作(zuo)時，物料和熱(re)(re)氣流(liu)依(yi)次進(jin)入內至(zhi)外筒體，在機(ji)體Z形往復(fu)折流(liu)后，充分利用熱(re)(re)能烘(hong)干(gan)(gan)物料后再卸出。
烘干機筒體部分由三個同軸(zhou)水(shui)平放置的內、中、外筒套疊組成，這就使筒體的截面(mian)(mian)(mian)得到充(chong)分的利用。其筒體外形總(zong)長(chang)度約為與之相(xiang)當的單筒的30-35%。從而大幅度地減(jian)少占地面(mian)(mian)(mian)積(ji)和廠房建筑面(mian)(mian)(mian)積(ji)。
該(gai)機的支(zhi)承裝置，是(shi)在外筒(tong)上輪(lun)(lun)(lun)帶與托(tuo)輪(lun)(lun)(lun)支(zhi)承，由(you)電機直(zhi)接(jie)(jie)帶動(dong)托(tuo)輪(lun)(lun)(lun)。通(tong)過托(tuo)輪(lun)(lun)(lun)與輪(lun)(lun)(lun)帶摩擦，使(shi)筒(tong)體轉動(dong)。該(gai)機總體結構緊湊、合理、簡單，為(wei)便于(yu)磨損件的檢修更換，在中(zhong)間設計成軸向剖分(fen)式(shi)，用螺栓固定連接(jie)(jie)。
工作原理
物(wu)(wu)料(liao)(liao)(liao)(liao)由供料(liao)(liao)(liao)(liao)裝置進(jin)(jin)(jin)(jin)入回轉(zhuan)滾筒(tong)(tong)的(de)(de)(de)內層(ceng)(ceng)(ceng),實現順流烘(hong)干(gan),物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)內層(ceng)(ceng)(ceng)的(de)(de)(de)抄(chao)(chao)板(ban)下不(bu)(bu)斷(duan)抄(chao)(chao)起、散落呈(cheng)螺旋行(xing)(xing)(xing)進(jin)(jin)(jin)(jin)式(shi)實現熱交換(huan)，物(wu)(wu)料(liao)(liao)(liao)(liao)移動至(zhi)(zhi)內層(ceng)(ceng)(ceng)的(de)(de)(de)另(ling)一端(duan)進(jin)(jin)(jin)(jin)入中(zhong)(zhong)層(ceng)(ceng)(ceng)，進(jin)(jin)(jin)(jin)行(xing)(xing)(xing)逆流烘(hong)干(gan)，物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)不(bu)(bu)斷(duan)地被(bei)反復揚進(jin)(jin)(jin)(jin)，呈(cheng)進(jin)(jin)(jin)(jin)兩步退一步的(de)(de)(de)行(xing)(xing)(xing)進(jin)(jin)(jin)(jin)方式(shi)，物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)中(zhong)(zhong)層(ceng)(ceng)(ceng)既充(chong)分(fen)吸收(shou)內層(ceng)(ceng)(ceng)滾筒(tong)(tong)散發的(de)(de)(de)熱量(liang)，又吸收(shou)中(zhong)(zhong)層(ceng)(ceng)(ceng)滾筒(tong)(tong)的(de)(de)(de)熱量(liang)，同時又延長了(le)干(gan)燥(zao)(zao)(zao)時間，物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)此(ci)(ci)達到(dao)干(gan)燥(zao)(zao)(zao)狀態。物(wu)(wu)料(liao)(liao)(liao)(liao)行(xing)(xing)(xing)至(zhi)(zhi)中(zhong)(zhong)層(ceng)(ceng)(ceng)另(ling)一端(duan)而(er)落入外層(ceng)(ceng)(ceng)，物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)外層(ceng)(ceng)(ceng)滾筒(tong)(tong)內呈(cheng)矩形多回路方式(shi)行(xing)(xing)(xing)進(jin)(jin)(jin)(jin)，達到(dao)干(gan)燥(zao)(zao)(zao)效果(guo)的(de)(de)(de)物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)熱風作用下快速(su)行(xing)(xing)(xing)進(jin)(jin)(jin)(jin)排出滾筒(tong)(tong)，沒有達到(dao)干(gan)燥(zao)(zao)(zao)效果(guo)的(de)(de)(de)濕物(wu)(wu)料(liao)(liao)(liao)(liao)因(yin)自重而(er)不(bu)(bu)能(neng)快速(su)行(xing)(xing)(xing)進(jin)(jin)(jin)(jin)，物(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)此(ci)(ci)矩形抄(chao)(chao)板(ban)內進(jin)(jin)(jin)(jin)行(xing)(xing)(xing)充(chong)分(fen)干(gan)燥(zao)(zao)(zao)，由此(ci)(ci)完成(cheng)干(gan)燥(zao)(zao)(zao)目的(de)(de)(de)。
