本發明涉(she)及熱處理(li)技(ji)術領域,特別涉(she)及一(yi)種(zhong)氣氛燒結(jie)爐。
背景技術:
隨(sui)著中國(guo)機械工業的發展(zhan),越(yue)來越(yue)多的機械設備已(yi)得到廣(guang)泛使用。
在(zai)工(gong)礦開(kai)采、生產(chan)制造(zao)類企業中,往往需要經過高(gao)溫(wen)處(chu)理(li)(li)工(gong)序(xu)。高(gao)溫(wen)設(she)備的(de)種類很(hen)多,其(qi)中比較常(chang)見的(de)有(you)燃(ran)煤鍋爐(lu)(lu)、電磁爐(lu)(lu)和(he)氣(qi)氛(fen)燒(shao)結爐(lu)(lu)等(deng)。以氣(qi)氛(fen)燒(shao)結爐(lu)(lu)為(wei)例,氣(qi)氛(fen)燒(shao)結爐(lu)(lu)是一種在(zai)高(gao)溫(wen)下,通(tong)入各(ge)種工(gong)藝氣(qi)體對產(chan)品進行燒(shao)結處(chu)理(li)(li),主要包括硬質合金(jin)燒(shao)結爐(lu)(lu)和(he)粉末(mo)冶金(jin)爐(lu)(lu)等(deng),也有(you)用于銅材,鋼(gang)帶退(tui)火等(deng)熱處(chu)理(li)(li),同樣可用于厚(hou)膜電路、厚(hou)膜電阻(zu)、電子元件電極(ji)、鋼(gang)加(jia)熱器、太陽(yang)能電池板等(deng)類似產(chan)品的(de)高(gao)溫(wen)燒(shao)結、熱處(chu)理(li)(li)。
氣氛燒(shao)結(jie)(jie)爐內對工件進行燒(shao)結(jie)(jie)時,在內膽中(zhong)通(tong)入各種工藝(yi)氣體(ti)(ti),比如(ru)氫(qing)、氧(yang)、氮和(he)惰性(xing)(xing)氣體(ti)(ti)等,工藝(yi)氣體(ti)(ti)中(zhong)攜帶(dai)有介質粉體(ti)(ti),其與工件表面(mian)相遇時,能夠提高制品致密化(hua)程度、獲得優良(liang)性(xing)(xing)能。、
目前,氣(qi)(qi)氛燒結爐(lu)通(tong)過(guo)工(gong)(gong)藝氣(qi)(qi)體(ti)(ti)(ti)(ti)對工(gong)(gong)件(jian)(jian)的處理方式,一(yi)般是(shi)通(tong)過(guo)引入一(yi)定量的工(gong)(gong)藝氣(qi)(qi)體(ti)(ti)(ti)(ti)在(zai)(zai)爐(lu)子(zi)的內(nei)(nei)膽內(nei)(nei)進(jin)行悶(men)燒,或者(zhe)在(zai)(zai)引入工(gong)(gong)藝氣(qi)(qi)體(ti)(ti)(ti)(ti)的同時排出工(gong)(gong)藝氣(qi)(qi)體(ti)(ti)(ti)(ti),由于工(gong)(gong)件(jian)(jian)的表面積一(yi)般較大(da),且長度(du)特征比較明顯,而同時內(nei)(nei)膽為了(le)保證真空(kong)度(du),在(zai)(zai)其側(ce)壁上一(yi)般只設(she)置有一(yi)個或幾(ji)個進(jin)氣(qi)(qi)口,因(yin)此現(xian)有技術(shu)中(zhong)往內(nei)(nei)膽中(zhong)通(tong)入工(gong)(gong)藝氣(qi)(qi)體(ti)(ti)(ti)(ti)的方式,往往無法使工(gong)(gong)藝氣(qi)(qi)體(ti)(ti)(ti)(ti)完全(quan)覆蓋到(dao)工(gong)(gong)件(jian)(jian)表面的每(mei)個角落,工(gong)(gong)件(jian)(jian)表面的燒結程度(du)不(bu)均勻。
因此(ci),如何提高工藝氣(qi)體與工件(jian)表面(mian)的(de)接觸(chu)面(mian)積,使工件(jian)表面(mian)的(de)燒結程度和處(chu)理效果變得均勻(yun),是本領(ling)域技(ji)術(shu)人員亟(ji)待(dai)解決的(de)技(ji)術(shu)問題(ti)。

在本發明所(suo)提供的一種具(ju)體實施(shi)方(fang)式中,氣(qi)氛燒結(jie)爐主要包括內膽1和(he)擾流部件2。
其(qi)中,內(nei)(nei)(nei)(nei)膽1為氣(qi)氛燒(shao)結爐的(de)重要(yao)組成部(bu)分,設(she)置(zhi)在(zai)(zai)(zai)氣(qi)氛燒(shao)結爐的(de)爐體3內(nei)(nei)(nei)(nei),工(gong)件在(zai)(zai)(zai)燒(shao)結時就放置(zhi)在(zai)(zai)(zai)內(nei)(nei)(nei)(nei)膽1內(nei)(nei)(nei)(nei),為加(jia)快燒(shao)結過程,內(nei)(nei)(nei)(nei)膽1內(nei)(nei)(nei)(nei)的(de)溫度一(yi)般(ban)很高。內(nei)(nei)(nei)(nei)膽1可呈圓筒狀或方筒狀,在(zai)(zai)(zai)其(qi)左右兩側設(she)置(zhi)有(you)保(bao)持內(nei)(nei)(nei)(nei)部(bu)高溫的(de)保(bao)溫門(men),一(yi)般(ban)由石(shi)墨制成。在(zai)(zai)(zai)燒(shao)結工(gong)件時,需要(yao)工(gong)件表面(mian)與工(gong)藝處理(li)氣(qi)體均勻接觸以提高工(gong)件的(de)燒(shao)結質量,為此,一(yi)般(ban)在(zai)(zai)(zai)內(nei)(nei)(nei)(nei)膽1的(de)側壁上(shang)設(she)置(zhi)有(you)不同位置(zhi)的(de)進氣(qi)口,以保(bao)證(zheng)氣(qi)氛均勻性。
擾(rao)流部件2設(she)置在內(nei)(nei)(nei)膽1內(nei)(nei)(nei),其(qi)可(ke)自由(you)旋(xuan)轉(zhuan),并且在其(qi)進(jin)(jin)行(xing)旋(xuan)轉(zhuan)時(shi)(shi)(shi),將(jiang)(jiang)對進(jin)(jin)入到(dao)(dao)(dao)內(nei)(nei)(nei)膽1中的(de)(de)工(gong)(gong)藝(yi)(yi)(yi)氣(qi)(qi)(qi)體(ti)進(jin)(jin)行(xing)強力攪動(dong),使得工(gong)(gong)藝(yi)(yi)(yi)氣(qi)(qi)(qi)體(ti)被吹(chui)散(san)。具體(ti)的(de)(de),考(kao)慮(lv)到(dao)(dao)(dao)工(gong)(gong)藝(yi)(yi)(yi)氣(qi)(qi)(qi)體(ti)從某個或某幾個進(jin)(jin)氣(qi)(qi)(qi)口處進(jin)(jin)入到(dao)(dao)(dao)內(nei)(nei)(nei)膽時(shi)(shi)(shi),工(gong)(gong)藝(yi)(yi)(yi)氣(qi)(qi)(qi)體(ti)的(de)(de)聚(ju)集度(du)較(jiao)高、密度(du)較(jiao)大,并且剛從進(jin)(jin)氣(qi)(qi)(qi)口噴出時(shi)(shi)(shi),其(qi)運動(dong)速(su)度(du)高度(du)一致,如(ru)此(ci)可(ke)將(jiang)(jiang)剛 進(jin)(jin)入到(dao)(dao)(dao)內(nei)(nei)(nei)膽1中的(de)(de)工(gong)(gong)藝(yi)(yi)(yi)氣(qi)(qi)(qi)體(ti)看作“工(gong)(gong)藝(yi)(yi)(yi)氣(qi)(qi)(qi)體(ti)團(tuan)(tuan)”。顯然,“工(gong)(gong)藝(yi)(yi)(yi)氣(qi)(qi)(qi)體(ti)團(tuan)(tuan)”所(suo)攜帶(dai)的(de)(de)大部分介(jie)(jie)質(zhi)粉體(ti)都(dou)集中在一處,與(yu)工(gong)(gong)件的(de)(de)接觸(chu)面(mian)(mian)積非常小,不利(li)于(yu)工(gong)(gong)件表(biao)面(mian)(mian)的(de)(de)燒(shao)結質(zhi)量。而(er)當(dang)“工(gong)(gong)藝(yi)(yi)(yi)氣(qi)(qi)(qi)體(ti)團(tuan)(tuan)”碰到(dao)(dao)(dao)擾(rao)流部件2的(de)(de)高速(su)旋(xuan)轉(zhuan)和(he)強力攪動(dong)時(shi)(shi)(shi),“工(gong)(gong)藝(yi)(yi)(yi)氣(qi)(qi)(qi)體(ti)團(tuan)(tuan)”就瞬間被打散(san)、擾(rao)亂,進(jin)(jin)入分散(san)成為密度(du)很(hen)小、分布很(hen)廣且迅(xun)速(su)遍布到(dao)(dao)(dao)整個內(nei)(nei)(nei)膽容積的(de)(de)“工(gong)(gong)藝(yi)(yi)(yi)氣(qi)(qi)(qi)體(ti)云”,如(ru)此(ci)“工(gong)(gong)藝(yi)(yi)(yi)氣(qi)(qi)(qi)體(ti)云”將(jiang)(jiang)非常容易地與(yu)工(gong)(gong)件的(de)(de)表(biao)面(mian)(mian)全接觸(chu),同時(shi)(shi)(shi)將(jiang)(jiang)攜帶(dai)的(de)(de)介(jie)(jie)質(zhi)粉體(ti)撒(sa)播到(dao)(dao)(dao)工(gong)(gong)件表(biao)面(mian)(mian)上,由(you)于(yu)“工(gong)(gong)藝(yi)(yi)(yi)氣(qi)(qi)(qi)體(ti)云”的(de)(de)分布廣、密度(du)較(jiao)均(jun)勻(yun)(yun),因此(ci)工(gong)(gong)件表(biao)面(mian)(mian)覆蓋的(de)(de)介(jie)(jie)質(zhi)粉體(ti)也同樣分布較(jiao)均(jun)勻(yun)(yun)。
因此,本發明所提(ti)供的(de)氣(qi)氛(fen)燒結(jie)爐,通過(guo)在內膽1內設置用于對(dui)工(gong)藝氣(qi)體進行攪動的(de)擾流部件2,使得工(gong)藝氣(qi)體的(de)分布更(geng)廣、更(geng)均勻,從(cong)而提(ti)高(gao)了工(gong)藝氣(qi)體與工(gong)件表(biao)面的(de)接觸面積(ji),使工(gong)件表(biao)面的(de)燒結(jie)程度和處理(li)效果變得更(geng)加均勻。
在關于(yu)擾(rao)流部(bu)(bu)件(jian)2的(de)(de)一種優選實施(shi)方(fang)式中(zhong),為方(fang)便地實現擾(rao)流部(bu)(bu)件(jian)2在內膽1內的(de)(de)轉(zhuan)(zhuan)動(dong)(dong)(dong),本實施(shi)例(li)在爐體(ti)3上設置(zhi)了專用于(yu)帶(dai)(dai)動(dong)(dong)(dong)擾(rao)流部(bu)(bu)件(jian)2旋(xuan)(xuan)轉(zhuan)(zhuan)的(de)(de)驅動(dong)(dong)(dong)電(dian)(dian)(dian)機(ji)4。驅動(dong)(dong)(dong)電(dian)(dian)(dian)機(ji)4的(de)(de)轉(zhuan)(zhuan)動(dong)(dong)(dong)是可控的(de)(de),同時轉(zhuan)(zhuan)速也是可調的(de)(de),此外還能正反(fan)轉(zhuan)(zhuan),如(ru)此通過驅動(dong)(dong)(dong)電(dian)(dian)(dian)機(ji)4帶(dai)(dai)動(dong)(dong)(dong)擾(rao)流部(bu)(bu)件(jian)2旋(xuan)(xuan)轉(zhuan)(zhuan)的(de)(de)方(fang)式,可以(yi)使得擾(rao)流部(bu)(bu)件(jian)2的(de)(de)工作(zuo)狀況(轉(zhuan)(zhuan)速、轉(zhuan)(zhuan)向)能夠(gou)根據工件(jian)燒(shao)結過程的(de)(de)具體(ti)要(yao)求而定(ding)。
具體的,由于(yu)爐體3內空間局促(cu),驅動(dong)電機4一般(ban)設(she)置(zhi)在(zai)爐體3的外壁(bi)外表面上(shang),如此(ci)驅動(dong)電機4可(ke)以通過傳動(dong)軸5與擾(rao)流部(bu)(bu)件(jian)(jian)2相連的方式驅動(dong)擾(rao)流部(bu)(bu)件(jian)(jian)2。由于(yu)擾(rao)流部(bu)(bu)件(jian)(jian)2設(she)置(zhi)在(zai)內膽(dan)(dan)1內,而驅動(dong)電機4設(she)置(zhi)在(zai)爐體3的外壁(bi),因此(ci)傳動(dong)軸5需(xu)要(yao)依次穿透爐體3的側(ce)壁(bi)和(he)內膽(dan)(dan)1的側(ce)壁(bi)。
此(ci)外,由于為(wei)了(le)保(bao)證工件(jian)在燒結(jie)過程中(zhong)的(de)(de)燒結(jie)質量,需要在爐體3內(nei)和(he)內(nei)膽1內(nei)保(bao)持真空(kong),因此(ci),為(wei)避免(mian)傳動軸5穿透爐體3的(de)(de)側(ce)壁時(shi)破壞其內(nei)的(de)(de)真空(kong)度(du),針對(dui)此(ci),本實(shi)施例還在傳動軸5與爐體3的(de)(de)結(jie)合部位處設置了(le)動密(mi)封(feng)件(jian)6,比如油封(feng)、軟填料等。該動密(mi)封(feng)件(jian)6能夠在傳動軸5的(de)(de)轉(zhuan)動過程中(zhong),與爐體3的(de)(de)側(ce)壁形(xing)成氣密(mi)封(feng),從而保(bao)證爐體3內(nei)的(de)(de)真空(kong)度(du)。

進一步的(de),為了(le)使控(kong)制(zhi)器7較精(jing)確地(di)判斷(duan)工(gong)(gong)(gong)件(jian)(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)的(de)燒(shao)(shao)結(jie)均勻(yun)程度(du),本實施例在內膽1的(de)內壁上設(she)置了(le)多(duo)個溫(wen)(wen)(wen)(wen)度(du)探(tan)(tan)頭(tou)8,并且各溫(wen)(wen)(wen)(wen)度(du)探(tan)(tan)頭(tou)8均與控(kong)制(zhi)器7信號連接(jie)(jie)。具體(ti)的(de),溫(wen)(wen)(wen)(wen)度(du)探(tan)(tan)頭(tou)8能夠探(tan)(tan)測出工(gong)(gong)(gong)件(jian)(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)的(de)溫(wen)(wen)(wen)(wen)度(du),而(er)多(duo)個溫(wen)(wen)(wen)(wen)度(du)探(tan)(tan)頭(tou)8同(tong)時(shi)(shi)(shi)(shi)檢測時(shi)(shi)(shi)(shi),即(ji)可形成工(gong)(gong)(gong)件(jian)(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)的(de)全(quan)面(mian)(mian)積(ji)溫(wen)(wen)(wen)(wen)度(du)分布圖(tu)(tu)。考慮(lv)到工(gong)(gong)(gong)藝(yi)(yi)氣(qi)體(ti)在被擾流部件(jian)(jian)(jian)2吹(chui)散并與工(gong)(gong)(gong)件(jian)(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)相接(jie)(jie)觸時(shi)(shi)(shi)(shi),工(gong)(gong)(gong)件(jian)(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)與工(gong)(gong)(gong)藝(yi)(yi)氣(qi)體(ti)之間勢必存在一定范圍內的(de)溫(wen)(wen)(wen)(wen)差,兩(liang)個具有(you)溫(wen)(wen)(wen)(wen)差的(de)物體(ti)互相接(jie)(jie)觸,必然(ran)就會(hui)產生熱(re)量傳遞(di),如(ru)此工(gong)(gong)(gong)件(jian)(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)的(de)瞬時(shi)(shi)(shi)(shi)溫(wen)(wen)(wen)(wen)度(du)就會(hui)在與工(gong)(gong)(gong)藝(yi)(yi)氣(qi)體(ti)接(jie)(jie)觸時(shi)(shi)(shi)(shi)發生變化(hua),可能升(sheng)高也可能會(hui)降低。而(er)控(kong)制(zhi)器7就根據各個溫(wen)(wen)(wen)(wen)度(du)探(tan)(tan)頭(tou)8所檢測到的(de)工(gong)(gong)(gong)件(jian)(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)各個部位的(de)瞬時(shi)(shi)(shi)(shi)溫(wen)(wen)(wen)(wen)度(du)變化(hua),形成工(gong)(gong)(gong)件(jian)(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)的(de)全(quan)面(mian)(mian)積(ji)瞬時(shi)(shi)(shi)(shi)溫(wen)(wen)(wen)(wen)度(du)變化(hua)分布圖(tu)(tu),根據此分布圖(tu)(tu)即(ji)可較精(jing)確地(di)判斷(duan)出工(gong)(gong)(gong)件(jian)(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)與工(gong)(gong)(gong)藝(yi)(yi)氣(qi)體(ti)的(de)接(jie)(jie)觸面(mian)(mian)積(ji),也即(ji)工(gong)(gong)(gong)件(jian)(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)的(de)燒(shao)(shao)結(jie)均勻(yun)程度(du)。
在關于(yu)擾(rao)(rao)流(liu)部(bu)件(jian)2的另一種優選實施(shi)方式中,該(gai)擾(rao)(rao)流(liu)部(bu)件(jian)2無需外部(bu)的驅(qu)動(dong)電機4的驅(qu)動(dong),當其設置(zhi)在內(nei)膽(dan)1內(nei)時,可以(yi)自(zi)動(dong)旋(xuan)轉。具體的,該(gai)擾(rao)(rao)流(liu)部(bu)件(jian)2為螺(luo)(luo)旋(xuan)槳葉(xie),設置(zhi)在內(nei)膽(dan)1側壁(bi)上(shang)的進氣(qi)(qi)口處,并且(qie)螺(luo)(luo)旋(xuan)槳葉(xie)具有沿軸(zhou)向傾斜一定角度的螺(luo)(luo)旋(xuan)流(liu)線型形狀,該(gai)形狀使(shi)得進氣(qi)(qi)口中通(tong)入快速流(liu)動(dong)的工(gong)(gong)藝(yi)氣(qi)(qi)體時,能夠將工(gong)(gong)藝(yi)氣(qi)(qi)體與螺(luo)(luo)旋(xuan)槳葉(xie)的軸(zhou)向撞擊力轉化為沿著(zhu)周向分布的扭(niu)矩載荷(he),從(cong)而推動(dong)螺(luo)(luo)旋(xuan)槳葉(xie)周向旋(xuan)轉。如此設置(zhi),擾(rao)(rao)流(liu)部(bu)件(jian)2即可利用工(gong)(gong)藝(yi)氣(qi)(qi)體的動(dong)能推動(dong)自(zi)身進行(xing)高速旋(xuan)轉,將工(gong)(gong)藝(yi)氣(qi)(qi)體吹散(san),節(jie)省了外部(bu)驅(qu)動(dong)的能源。
當(dang)然,相比于(yu)驅(qu)動(dong)(dong)電機4主動(dong)(dong)驅(qu)動(dong)(dong)的(de)(de)方式,被(bei)動(dong)(dong)旋(xuan)轉(zhuan)的(de)(de)擾(rao)流(liu)部件2對工(gong)藝(yi)氣體(ti)的(de)(de)攪動(dong)(dong)程度較低(di),針對此,本實施例在螺(luo)旋(xuan)槳(jiang)葉的(de)(de)內膽1的(de)(de)側壁上設置了多個螺(luo)旋(xuan)槳(jiang)葉,并(bing)且(qie)各螺(luo)旋(xuan)槳(jiang)葉沿(yan)著內膽1的(de)(de)軸向方向均勻分(fen)布。如此,當(dang)工(gong)藝(yi)氣體(ti)通過進氣口高(gao)速(su)涌入內膽1時,各個螺(luo)旋(xuan)槳(jiang)葉即可同時旋(xuan)轉(zhuan),并(bing)且(qie)迅速(su)地將工(gong)藝(yi)氣體(ti)團分(fen)散到工(gong)件表(biao)面的(de)(de)各個角落。
不(bu)僅如此,考慮到(dao)氣氛燒結(jie)爐在工作(zuo)時,內(nei)膽1的(de)溫(wen)(wen)度較高,為此,本實(shi)施例在擾(rao)流部(bu)件(jian)2的(de)表面上設置了用于抗高溫(wen)(wen)的(de)碳-碳復合(he)材(cai)料層,該碳-碳復 合(he)材(cai)料層是由(you)碳纖維及其(qi)增強的(de)碳基復合(he)材(cai)料,其(qi)強度隨著溫(wen)(wen)度的(de)升(sheng)(sheng)高而(er)升(sheng)(sheng)高,能夠耐2800℃以上的(de)高溫(wen)(wen)。
