Description of the Invention: [Technical Field] The present invention relates to an industrial bright furnace having a sheathed curved multi-layer inner wall, the crucible comprising a convexly curved furnace lining, and at least the furnace lining 17 There are also matching refractory bricks. [Prior Art] Different furnace structures, such as the Maerz brand annular shaft furnace or the parallel vertical storage furnace, have an annular furnace body, and the furnace body is defined by an inner wall which is provided by a sergeant or a hanging. When the heating is in contact with the combustible gas, the convex outer layer of the convex coating is immediately expanded and enlarged, so that the outer fireproof bricks are pushed outward to form a support. Since the squeezing action is not performed uniformly, the tension is formed to loosen the structure of the fireproof brick, and finally, many fireproof monuments may be broken. In addition, when the operation is stopped, cracks are caused by the phenomenon of shrinkage, and the cracks formed are easily invaded by foreign matter. When the furnace body is heated again, the above-mentioned effects are intensified, so that the increase is increased. Damage to the fire brick structure. Therefore, the damage formed after several heating and cooling processes may cause at least replacement of the outer wall convex layer. On the concave inner lining of the outer wall, the preloading effect on the structure is caused by the thermal expansion factor. SUMMARY OF THE INVENTION The purpose of this invention is mainly to avoid the above-mentioned disadvantages, and to create an industrial furnace having a furnace lining with high heat resistance and thus having a good operational safety of 200540384. The above object is solved in that the outer lining layer formed by the heat-resistant fireproof brick is interrupted in the circumferential direction through at least one balance region formed by the cement member, the balance region having a expansion joint, and the heat-resistant cement member is tied to Formed on the adjacent heat-resistant fireproof bricks, they are meshed with each other by the convex tooth structure, and are fixed to the metal inner layer of the cylindrical inner wall through the cement support.
【實施方式】 如於文獻中多次說明的Maerz品牌的豎爐，本發明的 至少兩彼此平行的爐身丨分別具有一環形通道2，而可燃 氣體係以箭頭3的方向導入該環形通道2中，故該可燃氣 體得以溢流至一未圖示出的蓄熱式的第二爐身。因此，向 内界定出環形通道2的圓柱形内壁4得受到高溫氣體的環 流，故其溫度於加熱石灰時得以高達約攝氏一千度。 於本發明實施例中所示的懸掛式内壁4結構係設有一 金屬式的内載層5，其間具有氣體流經的冷卻通道6。於 忒内載層5的底端處設有一固定器7用來固定一耐熱水泥 所澆鑄而成的支承下環8。該内載層5的兩側係為隔離層b 9，1 0所保濩。上述圓柱形内壁4的外緣分別形成有由耐 熱防火磚11，12所構成的抗磨外殼，而藉由耐熱防火磚u， 因而形成一外凸和一内凹的爐襯層13，14。 上述懸掛式的内壁4結構極少為人所應用，原因在於 傳統式的結構會有使用上的危險，因為高溫氣體會經由一 7 200540384 抽壞的外凸爐概層13到達該内載層5而予以破壞。根據 本發明的設計，藉由一從下方予以支撐的結構而得以避免 上述危險下來實現有利的懸掛式結構。 在炼爐的運作當中，持續的增溫會形成熱脹現象，因 此於内凹的爐襯層丨4上，會造成設置於該處之耐熱防火 f 2的1縮而/肖除其内應力，但在外凸爐有見f 13上卻將 t成擴張的現象。若本發明沒有下列即將說明的結構設計 時，本發明亦同樣合路& 日日„ 银Θ叙生刖述一開始即予以提及的耐熱防 _火磚11結構的鬆散問題。 ,為了避免因為熔爐之外凸的爐襯層13的加熱所形成的 ㈣而造成耐熱防火磚結構的損壞問題，爐…3設置 有至少一平衡區域15-18來早以士齡6 μ— ;予以令斷，而依據第2圖所示 的貫施例，於周向上传的勺却^罢士 厂I Γ7上係均勾δ又置有四個平衡區域15·18。 如弟4、5圖所示’每一单俺f a， Ρ, ^ +衡£域15_18具有兩於其間 圍、、堯一伸縮縫19的水泥元件2〇，21，兮卜 2 1 该水泥元件20，2 1 :周向上係與相鄰的耐熱防火磚， 二 μ , . 2相接’並且 错由例如許多叉狀的水泥支座 .,L 22 23而固定於金屬内載 玲 上。，它們具有平面式的橫 袖十人 衩面’因此它們僅得於一 個方向上可彈性伸縮，而相對 侍於 且万向上是不可彳Φ縮 的，故而可阻播其於垂直位置上的水泥元件2Q，2中縮 經由與彼此嚙合凸齒式的耐熱防火磚丨丨 人 四個平衡區域15]8上的水泥元件2()，2ι 切接， 或弧形的襯層區24-27。該襯層區24 Ή固疋凸出式 U之間以90。的弧面，並且襯# “於平衡區域15- 襯層區2切係彈性支座式地 200540384 固定為金屬内載層5上。因此，於襯層區得以避免分離和 局部性的過渡負荷。 上述平衡區域1 5-1 8的伸縮性大小係由伸縮縫1 9的寬 度來決定。而該伸縮縫1 9的寬度最好是當爐身達到運行 /JHL度日守’可讓平衡區域1 5 -1 8至少完全關閉或是於襯層區 24-27内形成壓力，而當爐身冷卻時，該壓力將於耐熱防 火磚1 1結構内的收縮和相對運動之前先行消散。 依據第6圖實施例，於周向上錯開設有兩伸縮縫28， 29，故兩水泥元件3〇，3 }咬合相接，而伸縮縫形成逑宮式 的曲徑形狀。 如第5、6圖實施例所示，平衡區域15的水泥元件， 21和30，31具有與外凸爐襯層13的耐熱防火磚u相同 的徑向寬度，故水泥支座22，23穿過相鄰的隔離層而得 以順利進行彎曲的動作。依據第7圖的實施例，水泥元件 32，33藉由一包圍部分水泥支座22，23的嵌條34，而 延伸至金屬内載層5，因此而圍繞著一個由隔離材料所充 填的空隙34。此外，透過該等嵌條34，35，水泥支座22， 23付以強化，故於襯層區24-27内的封閉式伸縮縫19上 形成相對於第5、6圖所示實施例之較大抗壓應力。 【圖式簡單說明】 第1圖係為一蓄熱式平行豎立爐之具有圓筒式内壁區 域的軸向剖面圖； 第2圖係為依據第i圖之爐體圓筒式内壁，並沿著匕 200540384 II線所作的徑向剖面圖； 第3圖係為依據第1圖所示之爐體的放大圖. 内髮 分剖 剖面 第4圖係為依據第3圖之箭頭iv的方向所示 區域的側視圖； 第5圖係為依據第3圖之ν·ν線之内壁所作的部 面圖；以及 第6、7圖係為依據第5圖之兩變化實施例的徑向 圖。 【主要元件符號說明】 1 爐身 2 環形通道 3 箭頭 4 圓柱形内壁 5 金屬内載層 6 冷卻通道 7 固定器 8 支承下環 9 隔離層 10 隔離層 11 耐熱防大轉 12 财熱防大g 13 外凸爐槻層 14 内凹的壚觀層 200540384[Embodiment] As the Maerz brand shaft furnace repeatedly described in the literature, at least two parallel furnace shafts of the present invention respectively have an annular passage 2, and the combustible gas system is introduced into the annular passage 2 in the direction of arrow 3. Therefore, the combustible gas can be overflowed to a second regenerative furnace body (not shown). Therefore, the cylindrical inner wall 4 defining the annular passage 2 inward is subjected to the circulation of the high-temperature gas, so that the temperature is as high as about one thousand degrees Celsius when the lime is heated. The suspended inner wall 4 structure shown in the embodiment of the present invention is provided with a metallic inner carrier layer 5 with a cooling passage 6 through which gas flows. A holder 7 is provided at the bottom end of the inner carrier layer 5 for fixing a support lower ring 8 cast by a heat resistant cement. The two sides of the inner carrier layer 5 are protected by the isolation layer b 9,1 0. The outer edges of the cylindrical inner wall 4 are respectively formed with wear-resistant outer casings composed of heat-resistant fireproof bricks 11, 12, and by the heat-resistant fireproof bricks u, a convex and a concave furnace lining 13, 14 are formed. The above-mentioned suspended inner wall 4 structure is rarely used for humans because the conventional structure has a danger of use because the high temperature gas reaches the inner carrier layer 5 via the outer relief layer 13 which is smashed by a 7 200540384. Destroy it. According to the design of the present invention, an advantageous suspension structure can be realized by a structure supported from below to avoid the above danger. During the operation of the furnace, the continuous increase of temperature will cause thermal expansion. Therefore, on the concave lining layer 4, the heat-resistant fire prevention f 2 installed therein will be reduced/distracted. However, in the outer convex furnace, there is a phenomenon in which f 13 is expanded. If the present invention does not have the structural design to be described below, the present invention is also similar to the loosening problem of the structure of the heat-resistant _ fire brick 11 mentioned at the beginning of the day. Because of the damage caused by the heat generated by the heating of the convex lining 13 of the furnace (4), the furnace 3 is provided with at least one balance region 15-18 to be earlier than 6 μm; According to the example shown in Fig. 2, the scoop that is uploaded in the circumferential direction is the same as that of the striker factory I Γ7, and there are four balance areas 15·18. As shown in the pictures of brothers 4 and 5 Each single 俺fa, Ρ, ^ + 衡£ domain 15_18 has two cement elements 2, 21, 2, 2, 2, 2, 1 Adjacent heat-resistant fire bricks, two μ, . 2 are connected to each other and are misplaced by, for example, a plurality of fork-shaped cement bearings. L 22 23 is fixed on the metal inside. They have flat horizontal sleeves for ten people.衩 ' ' so they only have to be elastically stretchable in one direction, and the opposite is 10,000 Therefore, the cement elements 2Q, 2 in the vertical position can be prevented from being spliced through the cement elements 2 () on the four balance areas 15] 8 of the heat-resistant fire-proof bricks that are engaged with each other. Or curved lining zone 24-27. The lining zone 24 is tamped and protruded between the U-shaped U-shaped with 90., and the lining #" in the balance zone 15 - the lining zone 2 tangential elastic support The 200540384 is fixed to the metal inner carrier layer 5. Therefore, it is possible to avoid separation and localized transient loads in the lining zone. The size of the above-described balance area 1 5-1 8 is determined by the width of the expansion joint 19. The width of the expansion joint 19 is preferably such that when the furnace body reaches the running/JHL degree, the balance area 1 5 -1 8 can be at least completely closed or the pressure is formed in the lining area 24-27. When the body cools, the pressure will dissipate before the contraction and relative motion within the structure of the heat-resistant fireproof brick. According to the embodiment of Fig. 6, two expansion joints 28, 29 are provided in the circumferential direction, so that the two cement elements 3〇, 3} are engaged and joined, and the expansion joints form a labyrinth shape. As shown in the embodiment of Figs. 5 and 6, the cement elements 21, 30, 31 of the balance region 15 have the same radial width as the heat-resistant fire-resistant bricks u of the outer lining layer 13, so that the cement supports 22, 23 pass through. Adjacent barrier layers allow for smooth bending. According to the embodiment of Fig. 7, the cement elements 32, 33 extend to the metal inner carrier layer 5 by a panel 34 surrounding the partial cement supports 22, 23, thus surrounding a gap filled by the insulating material. 34. In addition, the cement supports 22, 23 are reinforced by the panels 34, 35, so that the closed expansion joints 19 in the lining regions 24-27 are formed relative to the embodiment shown in Figures 5 and 6.
