產品(pin)概況
回轉(zhuan)式三筒烘(hong)干機(ji)改進(jin)原(yuan)單(dan)筒烘(hong)干機(ji)內(nei)部(bu)結構,增加入機(ji)前(qian)濕(shi)料的(de)預(yu)烘(hong)干和延長濕(shi)料在機(ji)內(nei)烘(hong)干時間,再加上密封、保溫以及合理的(de)配套(tao)措施,使烘(hong)干機(ji)生(sheng)產(chan)能力與原(yuan)單(dan)筒式烘(hong)干機(ji)相比,提高48-80%,單(dan)位(wei)容積(ji)蒸(zheng)發強(qiang)度可達(da)120-180kg/m3,標準煤(mei)耗(hao)僅(jin)為6-8kg/t。其技術先進(jin)、運行(xing)參(can)數合理,操作簡單(dan)可行(xing),廣泛(fan)應(ying)用(yong)于各(ge)個(ge)行(xing)業的(de)礦渣、粘土(tu)、煤(mei)。
產品(pin)結構
三(san)筒(tong)(tong)烘(hong)干(gan)機(ji)(ji)是通過對單(dan)筒(tong)(tong)烘(hong)干(gan)機(ji)(ji)的(de)單(dan)筒(tong)(tong)體(ti)(ti)改為套疊在一起的(de)三(san)筒(tong)(tong),以縮短烘(hong)干(gan)機(ji)(ji)體(ti)(ti)的(de)外形(xing)尺寸。該機(ji)(ji)工作(zuo)時,物料(liao)和熱(re)氣流依次(ci)進入內至外筒(tong)(tong)體(ti)(ti),在機(ji)(ji)體(ti)(ti)Z形(xing)往(wang)復(fu)折流后(hou),充(chong)分利用熱(re)能(neng)烘(hong)干(gan)物料(liao)后(hou)再卸出。
烘干機筒(tong)體部分由三個同軸水平放置的內、中(zhong)、外筒(tong)套(tao)疊(die)組成,這就使筒(tong)體的截(jie)面(mian)得到充分的利用。其筒(tong)體外形總長度約(yue)為與之相當的單(dan)筒(tong)的30-35%。從(cong)而(er)大幅度地(di)減少占地(di)面(mian)積和廠房建筑面(mian)積。
該機(ji)(ji)(ji)的(de)支(zhi)承(cheng)裝置,是在(zai)外筒上輪帶(dai)(dai)與托(tuo)輪支(zhi)承(cheng),由(you)電(dian)機(ji)(ji)(ji)直接(jie)帶(dai)(dai)動(dong)托(tuo)輪。通過托(tuo)輪與輪帶(dai)(dai)摩擦,使筒體轉動(dong)。該機(ji)(ji)(ji)總體結(jie)構緊湊、合理、簡單,為(wei)便于磨損(sun)件(jian)的(de)檢修更(geng)換,在(zai)中間設計成軸(zhou)向剖(pou)分式,用螺栓固定連接(jie)。
工作原(yuan)理(li)
物(wu)(wu)料(liao)(liao)(liao)由供料(liao)(liao)(liao)裝置(zhi)進(jin)入回轉滾筒(tong)的(de)(de)(de)內層(ceng)(ceng),實現順(shun)流烘干(gan)(gan)(gan),物(wu)(wu)料(liao)(liao)(liao)在內層(ceng)(ceng)的(de)(de)(de)抄板下不(bu)斷抄起(qi)、散落呈(cheng)螺旋行(xing)(xing)(xing)進(jin)式實現熱交換(huan),物(wu)(wu)料(liao)(liao)(liao)移動(dong)至內層(ceng)(ceng)的(de)(de)(de)另一端(duan)進(jin)入中(zhong)(zhong)(zhong)層(ceng)(ceng),進(jin)行(xing)(xing)(xing)逆流烘干(gan)(gan)(gan),物(wu)(wu)料(liao)(liao)(liao)在中(zhong)(zhong)(zhong)層(ceng)(ceng)不(bu)斷地被(bei)反復揚進(jin),呈(cheng)進(jin)兩步(bu)退(tui)一步(bu)的(de)(de)(de)行(xing)(xing)(xing)進(jin)方(fang)式,物(wu)(wu)料(liao)(liao)(liao)在中(zhong)(zhong)(zhong)層(ceng)(ceng)既(ji)充分吸收(shou)內層(ceng)(ceng)滾筒(tong)散發的(de)(de)(de)熱量,又吸收(shou)中(zhong)(zhong)(zhong)層(ceng)(ceng)滾筒(tong)的(de)(de)(de)熱量,同時又延長(chang)了干(gan)(gan)(gan)燥時間(jian),物(wu)(wu)料(liao)(liao)(liao)在此達到干(gan)(gan)(gan)燥狀態。物(wu)(wu)料(liao)(liao)(liao)行(xing)(xing)(xing)至中(zhong)(zhong)(zhong)層(ceng)(ceng)另一端(duan)而落入外層(ceng)(ceng),物(wu)(wu)料(liao)(liao)(liao)在外層(ceng)(ceng)滾筒(tong)內呈(cheng)矩形(xing)多(duo)回路方(fang)式行(xing)(xing)(xing)進(jin),達到干(gan)(gan)(gan)燥效果(guo)的(de)(de)(de)物(wu)(wu)料(liao)(liao)(liao)在熱風作用(yong)下快(kuai)速(su)行(xing)(xing)(xing)進(jin)排(pai)出滾筒(tong),沒有達到干(gan)(gan)(gan)燥效果(guo)的(de)(de)(de)濕物(wu)(wu)料(liao)(liao)(liao)因自重(zhong)而不(bu)能快(kuai)速(su)行(xing)(xing)(xing)進(jin),物(wu)(wu)料(liao)(liao)(liao)在此矩形(xing)抄板內進(jin)行(xing)(xing)(xing)充分干(gan)(gan)(gan)燥,由此完成(cheng)干(gan)(gan)(gan)燥目的(de)(de)(de)。
