Description

Technical Field

[0001] This invention belongs to the field of manufacturing and installation, and relates to a box-type furnace, particularly to a transport structure for the box-type furnace and a method for manufacturing it. This invention also relates to a method for manufacturing a container. Background Technology

[0002] In the field of methane steam reforming, box furnaces used in hydrogen production conversion systems need to be transported from the manufacturing plant to the user's site. Since refractory linings need to be installed inside the box furnaces, protection of the refractory linings must be considered during transportation.

[0003] Transporting the entire box furnace with its refractory lining installed directly to the user's site can effectively protect the internal refractory lining; however, it occupies more transport space. This not only increases transportation costs but also sometimes exceeds the size limitations of the transport process, making it impossible to implement.

[0004] Therefore, there are currently two common methods for transporting and assembling this type of box furnace. One method is to horizontally cut the entire box furnace into several sections along its height, and then connect them on-site. The other method is to transport the entire box furnace separately, including the panels, steel structure, and refractory lining. Upon arrival at the user's site, they are then reassembled; that is, the refractory lining is installed only after the steel structure and panels are assembled.

[0005] The first method has the disadvantage that even when segmented along the height, the dimensions are still relatively large, occupying a significant amount of transport space. The second method suffers from low on-site assembly efficiency and increased risk of damage to the exposed refractory lining during on-site construction. Furthermore, additional lining protection measures are required during transport, resulting in excessive packaging costs.

[0006] Therefore, a solution is needed to make the entire manufacturing process of box furnaces easier. Summary of the Invention

[0007] The purpose of this invention is to provide a box furnace and its transportation structure and manufacturing method, which can facilitate the manufacturing of the box furnace.

[0008] Another object of the present invention is to provide a method for manufacturing a container, which facilitates the manufacturing of the container.

[0009] This invention provides a box-type furnace having four box sidewalls extending longitudinally and forming a closed quadrilateral in the circumferential direction. The box-type furnace includes four docking modules, each docking module including an L-shaped wall extending longitudinally and having an L-shaped cross-section. The four L-shaped walls belonging to the four docking modules are connected in pairs along the circumferential direction by docking structures, thereby forming a closed quadrilateral and respectively constituting the four corners cut from the closed quadrilateral.

[0010] In one embodiment, each docking module further includes a bottom wall and / or a top wall. The bottom wall connects longitudinally to the L-shaped bottom edge of the corresponding docking module's L-shaped wall, and the bottom walls of the four docking modules are joined together to form the bottom wall of the box furnace. The top wall connects longitudinally to the L-shaped top edge of the corresponding docking module's L-shaped wall, and the top walls of the four docking modules are joined together to form the top wall of the box furnace.

[0011] In one implementation, the closed quadrilateral is rectangular. The cross-sections of the L-shaped walls of the four docking modules are identical in size.

[0012] In one embodiment, in the mating structure, two mating posts are respectively connected to the outer sides of two adjacent L-shaped walls at their joint, and include two mating surfaces facing each other. A gasket is sandwiched between the two mating surfaces belonging to the two mating posts. Fasteners pass through the two mating surfaces and the gasket, thereby connecting the two mating posts and subsequently the two adjacent L-shaped walls. Solder fills the space between the two mating surfaces and on the outer side of the gasket.

[0013] The present invention also provides a transport structure for a box-type furnace, the box-type furnace having four box side walls extending longitudinally and forming a closed quadrilateral in the circumferential direction. The transport structure includes a pair of docking modules, each docking module including an L-shaped wall configured to extend longitudinally and have an L-shaped cross-section. The pair of L-shaped walls belonging to the pair of docking modules are connected to each other by a temporary connecting structure to form another quadrilateral smaller than the closed quadrilateral. The pair of L-shaped walls are configured to respectively form two of the four corners cut from the closed quadrilateral.

[0014] In one embodiment, each docking module further includes a bottom end wall and / or a top end wall. The bottom end wall continues longitudinally to the L-shaped bottom edge of the L-shaped wall of the corresponding docking module and is configured to form part of the bottom wall of the box furnace. The top end wall continues longitudinally to the L-shaped top edge of the corresponding docking module and is configured to form part of the top wall of the box furnace. A pair of docking modules are longitudinally offset such that the bottom end walls of the pair of docking modules are spaced apart from each other by a predetermined distance, and / or, the top end walls of the pair of docking modules are spaced apart from each other by a predetermined distance.

[0015] In one implementation, the closed quadrilateral is rectangular. The cross-sections of the L-shaped walls of the pair of mating modules are identical in size.

[0016] In one embodiment, the temporary connection structure includes two angle steels, each L-shaped wall having a mating post on the outer side of both ends. Each angle steel has two sides connected to the mating posts of the pair of L-shaped walls at their joints via fasteners, thereby connecting the pair of L-shaped walls together using the two angle steels and fasteners.

[0017] This invention provides a method for manufacturing a box-type furnace. The box-type furnace to be manufactured has four side walls extending longitudinally and forming a closed quadrilateral in the circumferential direction. The manufacturing method includes a preparation step and an assembly step. In the preparation step, four docking modules are prepared, such that each docking module includes an L-shaped wall that is configured to extend longitudinally and has an L-shaped cross-section, and the four L-shaped walls belonging to the four docking modules are prepared to respectively form the four corners cut from the closed quadrilateral. In the assembly step, the four L-shaped walls are joined together in pairs along the circumferential direction through the docking structure, thereby forming a closed quadrilateral, thus obtaining the box-type furnace.

[0018] In one embodiment, during the fabrication step, each docking module further includes a bottom wall and / or a top wall. The bottom wall connects longitudinally to the L-shaped bottom edge of the corresponding L-shaped wall of the docking module, and the top wall connects longitudinally to the L-shaped top edge of the corresponding L-shaped wall of the docking module. During the assembly step, the bottom walls of the four docking modules are joined together to form the bottom wall of the box furnace, and the top walls of the four docking modules are joined together to form the top wall of the box furnace.

[0019] In one embodiment, during the fabrication step, four docking modules with identical cross-sectional dimensions are fabricated to form L-shaped walls. The closed quadrilateral is rectangular.

[0020] In one embodiment, during the fabrication step, mating posts are provided on the outer sides of both ends of each L-shaped wall. During the assembly step, the ends of two adjacent L-shaped walls are mated together, such that the two mating surfaces of the mating posts belonging to the two adjacent L-shaped walls face each other. A gasket is sandwiched between the two mating surfaces, and fasteners are passed through the two mating surfaces and the gasket to connect the two mating posts, and thus the two adjacent L-shaped walls. Then, welding is performed on the outer sides of the gasket to securely connect the two mating surfaces, and thus the two adjacent L-shaped walls.

[0021] In one embodiment, a preparation step is performed at a first location, and an assembly step is performed at a second location. At the first location, every two of the four docking modules prepared in the preparation step are paired to assemble two transport structures for the box furnaces, which are then transported to the second location. At the second location, prior to the assembly step, a disassembly step is performed to disassemble the docking modules from the two transport structures, resulting in the four docking modules used in the assembly step. Each transport structure includes a pair of docking modules. Dock supports are provided on the outer sides of both ends of the L-shaped wall of each docking module. The pair of L-shaped walls belonging to a pair of docking modules connect to form another quadrilateral smaller than the closed quadrilateral. The two L-shaped walls are configured to form two of the four corners cut from the closed quadrilateral. Each docking module also includes two angle steels, and in the transport structure, the two sides of each angle steel are connected to the dock supports of the pair of L-shaped walls at their joints via fasteners.

[0022] This invention also provides a method for manufacturing a container. The container to be manufactured has N sidewalls extending longitudinally and forming a closed shape circumferentially. The manufacturing method includes a preparation step and an assembly step. In the preparation step, N docking modules are prepared, such that each docking module includes a wall segment extending longitudinally, and the N wall segments belonging to the N docking modules are prepared to form N segments cut circumferentially from the closed shape. The N wall segments are arranged to be divided into several groups, and at least two wall segments in each group are arranged to be connected to each other to form another closed shape smaller than the closed shape. In the assembly step, the N wall segments are connected pairwise along the circumferential direction through the docking structure to form a closed shape, thereby obtaining the container.

[0023] In one embodiment, a preparation step is performed at a first location, and an assembly step is performed at a second location, wherein N segments are formed by dividing a closed shape into N equal parts circumferentially. At the first location, every two docking modules from the N docking modules prepared in the preparation step are paired to assemble a transport structure of M containers, which is then transported to the second location, where M = N / 2. At the second location, prior to the assembly step, a disassembly step is performed to disassemble the docking modules from the M transport structures, thereby obtaining the N docking modules used in the assembly step. Each transport structure includes a pair of docking modules, the wall segments of which are connected to each other by a temporary connecting structure to form another closed shape.

[0024] When the box furnace is constructed and manufactured using the above-described method, it is cut into four corners, allowing the refractory lining to be installed in the manufacturing workshop as part of the L-shaped wall. This reduces on-site construction work and lowers exposure risks during construction. Furthermore, the construction and manufacturing method make it possible to transport the furnace components using the aforementioned transport structure. This significantly reduces transport space and provides reliable protection for the already installed refractory lining during transport. Therefore, the box furnace, its transport structure, and manufacturing method facilitate the production of box furnaces.

[0025] Similarly, the above-described method for making containers also facilitates the production of containers. Attached Figure Description

[0037] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. However, it should be understood that the present invention is not limited to the embodiments described below, and the technical concept of the present invention can be implemented in combination with other known technologies or functions, or with other technologies similar to those known technologies.

[0038] For example, if the first feature described subsequently in the specification is formed above or on the second feature, this can include embodiments where the first and second features are formed by direct connection, or embodiments where an additional feature is formed between the first and second features, so that the first and second features are not directly connected. Furthermore, when the first element is described in a manner connected or combined with the second element, the description includes embodiments where the first and second elements are directly connected or combined with each other, as well as embodiments where one or more other intervening elements are incorporated to indirectly connect or combine the first and second elements with each other.

[0039] The following is combined Figures 1A to 7 Embodiments according to the present invention are described below. It is understood that the accompanying drawings are merely illustrative and are not necessarily drawn to scale, and should not be construed as limiting the scope of protection actually claimed by the present invention.

[0040] This invention provides a box furnace 10. The box furnace 10 is a furnace with a generally hexahedral body, capable of accommodating high-temperature activities such as combustion reactions. For example, the illustrated box furnace 10 is used in a hydrogen production conversion furnace system for methane steam reforming (SMR) processes. Box furnaces 10 are also commonly used in ethylene cracking furnaces and catalytic reforming furnace systems. Figure 1A and Figure 1B Taking the box furnace 10 of the hydrogen production conversion furnace system shown as an example, the box furnace 10 includes an outer frame and a refractory lining 60 protected by the outer frame (see also...). Figure 2A and Figure 2B The outer frame includes steel structure 40, panels 50, etc. Steel structure 40 typically includes main columns 401 located at the four corners for primary support, secondary columns 402 distributed between adjacent main columns 401, and beams 403 typically perpendicular to the columns. Panels 50 are usually formed by welding or other means, supported by steel structure 40, to constitute the various surfaces of the box furnace 10. Figure 1A and Figure 1B The diagram also shows that the main columns 401 located at the four corners protrude downwards by a certain distance relative to the bottom panel 50, and this protruding part can be regarded as the support legs of the box furnace 10. Figure 1A and Figure 1B The diagram shows a typical working state of the box furnace 10. In this state, the columns 401, 402, etc., usually extend vertically, while the crossbeam 403 usually extends horizontally.

[0041] The refractory lining 60 can be made of refractory fiber materials, such as ceramic fiber materials. Typically, on one side of the box furnace 10, the refractory lining 60 can be formed by assembling multiple panels (or modules). The refractory lining 60 is usually protected by an outer frame, particularly its panel 50, encircling the interior. In practical engineering, the refractory lining 60 can include multiple layers, such as a backing board / blanket and fiber modules located inside the backing board / blanket. The fiber modules can be integral and / or layered ceramic fiber products or other refractory fiber products, such as environmentally friendly fiber products. The backing board / blanket can be, for example, a ceramic fiber board, an environmentally friendly fiber blanket, or a nanoboard. In other words, the refractory lining 60 can also be made of more than two materials.

[0042] Combination Figures 1A to 2B The box furnace 10 has four box side walls 11 extending along the longitudinal direction H1 and forming a closed quadrilateral T0 in the circumferential direction C0. In other words, the four box side walls 11 constitute the four sides of the aforementioned hexahedron, and the bottom and top surfaces will be mentioned later. Generally, after the box furnace 10 is manufactured (or assembled) and erected, the longitudinal direction H1 is the vertical or height direction of the box furnace 10, while the circumferential direction C0 is generally the horizontal or transverse direction around the box furnace 10.

[0043] The box furnace 10 includes four docking modules 1a, 1b, 1c, and 1d, which are collectively referred to as docking module 1 without distinction in description.

[0044] Combination Figures 1A to 2B Each docking module 1 includes an L-shaped wall 2 extending longitudinally along H1 and having an L-shaped cross-section, referred to in the description as L-shaped walls 2a, 2b, 2c, and 2d respectively. See also... Figure 2B The L-shaped wall 2 includes a pair of generally straight wall segments 21 and 22, one end of which is connected to each other in the figure (on the circumferential direction C0), so that the pair of straight wall segments 21 and 22 are connected at an angle to each other, or vertically in the figure, thus forming an L-shape.

[0045] Combination Figure 2A and Figure 2B The four L-shaped walls 2a, 2b, 2c, and 2d, belonging to the four docking modules 1a, 1b, 1c, and 1d respectively, are connected in pairs along the circumferential direction C0 via the docking structure 6, thus forming a closed quadrilateral T0 and respectively constituting the four corners cut from the closed quadrilateral T0. That is, the four L-shaped walls 2 are connected at their ends (i.e., along the circumferential direction C0) at the four corners. Figure 2BThe free ends of the straight wall segments 21 and 22 in the diagram (that is, the end faces of the two ends 28 of the L-shaped wall 2) are connected end-to-end, so that each L-shaped wall, such as 2a, is connected to two L-shaped walls, such as 2b and 2d, respectively, through its two ends 28, ultimately forming a closed quadrilateral T0. The closed quadrilateral T0 is then cut (or deconstructed or broken down) into four corners, which roughly correspond to the L-shapes formed by the four L-shaped walls 2. In other words, with... Figure 2B Taking the clockwise direction of the circumferential C0 in the diagram as an example, the downstream end of each L-shaped wall 2 in the clockwise direction can be called the tail end, and the upstream end can be called the head end. The head end of each L-shaped wall 2 (e.g., 2a) is connected to the tail end of the adjacent L-shaped wall 2 (e.g., 2d) in the clockwise direction, while the tail end of each L-shaped wall 2 (e.g., 2a) is connected to the head end of another adjacent L-shaped wall 2 (e.g., 2b) in the clockwise direction, which is located downstream.

[0046] It is understood that the aforementioned butt joints or splices of the L-shaped walls 2 indicate that the outer frame, composed of the steel structure 40, panel 50, etc., needs to be cut, and the corresponding internal refractory lining 60 is also cut into corresponding panels. Each straight wall segment 21 of the L-shaped wall 2 may contain a corresponding complete panel or multiple spliced ​​panels. For the box furnace 10 shown in the figure, the L-shaped wall 2 may substantially include correspondingly cut panels 50, correspondingly cut refractory lining 60, and even correspondingly cut steel structure 40. That is, this description does not limit the L-shaped wall 2 to a single-layer wall or to a monolithic wall.

[0047] When using the aforementioned box furnace 10 structure, the refractory lining 60 can be installed in the manufacturing workshop, thus reducing the exposure risk during on-site installation. It is worth noting that some regions have specific safety requirements regarding this aspect.

[0048] Since the refractory lining 60 can be installed in the manufacturing workshop, the assembly of the box side wall 11 can be completed by connecting the four docking modules 1 in pairs at the user site. Therefore, less scaffolding is required at the user site, and on-site welding work can also be reduced, which not only reduces costs but also increases the safety of construction workers.

[0049] When the box furnace 10 adopts the above-described structure, two docking modules, such as 1a and 1c, can be paired during transportation to form another closed shape, thereby significantly reducing the transportation size while protecting the internal refractory lining 60. Moreover, it can be quickly assembled upon arrival at the customer's site. These details will be described in more detail later.

[0050] See Figure 4 Each docking module 1 may also include a bottom wall 3 and / or (in the figure, “and”) a top wall 4. Figure 4 The two top walls 4 indicated in the diagram belong to a pair of mating modules 1a and 1c. It is understood that the term "and / or" as used herein includes any and all combinations of one or more of the related listed items. Unless otherwise stated, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood in the art to which this invention pertains. It should also be understood that terms, such as those defined in common dictionaries, should be understood to have the same meaning as they have in the context of this specification and the related art, and should not be interpreted in an idealized or overly formal sense unless expressly stated herein. For the sake of brevity and / or clarity, well-known functions or constructions may not be described in detail.

[0051] Combination Figure 3B and Figure 4 The bottom wall 3 connects to the L-shaped bottom edge 23 of the corresponding docking module 1 along the longitudinal direction H1. Further integration Figure 1A and Figure 5 The bottom walls 3 of the four docking modules 1 are spliced ​​together to form the bottom wall 13 of the box furnace 10. Similar to the bottom wall 3, the top wall 4 connects to the L-shaped top edge 24 of the L-shaped wall 2 of its respective docking module 1 along the longitudinal direction H1. The top walls 4 of the four docking modules 1 are spliced ​​together to form the top wall 14 of the box furnace 10. It can be understood that the bottom wall 13 and the top wall 14 respectively constitute the bottom and top surfaces of the aforementioned hexahedron. (Reference) Figure 5 The bottom wall 3 (and similarly the top wall 4) can form a quarter of the bottom wall 13 (and similarly the top wall 14) of the box after a cross-cut.

[0052] In this way, the L-shaped wall 2 of the docking module 1 is blocked at both ends in the longitudinal direction H1 by the bottom wall 3 and the top wall 4, which can better protect the fire-resistant lining 60. Moreover, it can also improve the efficiency of on-site construction after arriving at the customer's site.

[0053] See Figure 2A The closed quadrilateral T0 can be a rectangle. The cross-sections of the L-shaped walls 2 of the four docking modules 1a, 1b, 1c, and 1d are identical in size. That is, the cross-sections of the four L-shaped walls 2 are congruent L-shapes with the same shape and size. For example, the dimensions of the four cross-sections corresponding to the length direction of the rectangle are approximately the same, and the dimensions corresponding to the width direction of the rectangle are also approximately the same. Figure 2A and Figure 2B In this process, the rectangle, which serves as an example of a closed quadrilateral T0, can be cut into four identical right angles using a cross cut (see the cross centered at point O0 in the diagram). The L-shapes formed by the L-shaped walls 2 of these four docking modules 1 correspond to this. Thus, the two transport structures 20 mentioned later (see...) Figures 3A to 4 The consistent size makes them easier to transport without restrictions.

[0054] Figure 6 yes Figure 2A A magnified view of the area near docking structure 6, as indicated in the diagram. See also... Figure 6 The mating structure 6 includes two mating posts 61, a gasket 62, a fastener 63, and solder 64. The two mating posts 61 are respectively connected to the outer sides of the joint P0 of two adjacent L-shaped walls 2, and include two opposing mating surfaces 611. Figure 2A It is understood that the term "outer side" here refers to the inner and outer angles of the L-shaped wall 2, or to the closed quadrilateral T0 formed or to be formed by the L-shaped wall 2. Unless otherwise specified, this reference is generally used when referring to "inner" and "outer" in the text. In the figure, the connecting column 61 can be made of channel steel, and the outer surface of the channel bottom (referring to the groove of the channel steel) constitutes the aforementioned connecting surface 611. The connecting column 61 can actually be formed by one of the secondary columns 402 that are originally required in the box furnace 10, as long as the secondary column 402 is set at the joint P0. In fact, the two channel steels welded together (as an example of the connecting column 61) constitute an integral column similar to an I-beam, which can be regarded as a secondary column 402. Other secondary columns 402 between adjacent main columns 401 can all be made of I-beams, for example, see Figure 3A .

[0055] Back Figure 6 A gasket 62 is sandwiched between the two mating surfaces 611 of the two mating posts 61. The gasket 62 is, for example, a ceramic fiber tape. A fastener 63 passes through the two mating surfaces 611 and the gasket 62, thereby connecting the two mating posts 61 to two adjacent (i.e., adjacent in the circumferential direction C0) L-shaped walls 2. The fastener can be, for example, a bolt, screw, rivet, etc.

[0056] Solder 64 is filled between the two mating surfaces 611 and on the outside of the gasket 62. The construction described herein is intended to further fix and connect the two mating surfaces 611 and the two adjacent L-shaped walls 2 by welding, and also to provide a reliable seal.

[0057] The aforementioned docking structure 6 can tightly connect two adjacent docking modules 1, especially their L-shaped walls 2, and reliably seal them, preventing internal heat from easily dissipating to the external environment.

[0058] Figure 6 The refractory lining 60, which is filled with a pattern of three vertical bars and three horizontal bars arranged in an alternating pattern, can be seen more clearly in the middle, compared to the sheet-like panel 50 covering the outside of the refractory lining 60.

[0059] As mentioned above, the structure of the box furnace 10 facilitates transportation. This invention also provides a method for transporting the box furnace 10, and in particular, provides a transport structure 20 for the box furnace 10, which can be specifically referred to... Figures 3A to 4 The transport structure 20 is the structure used during the transport of materials (or, elements constituting the box furnace 10) in order to ultimately manufacture the box furnace 10.

[0060] The transport structure 20 includes a pair of docking modules 1 (e.g., 1a, 1c). Each docking module 1 includes an L-shaped wall 2 configured to extend along the longitudinal direction H1 and have an L-shaped cross-section. That is, after the box furnace 10 is subsequently assembled, the L-shaped wall 2 in the box furnace 10 extends along the longitudinal direction H1.

[0061] A pair of L-shaped walls 2 (e.g., 2a, 2b) belonging to the aforementioned pair of docking modules 1a and 1c are connected to each other by a temporary connection structure 7 to form another quadrilateral T1 that is smaller than the closed quadrilateral T0. The aforementioned pair of L-shaped walls 2a and 2b are configured to form two of the four corners cut from the closed quadrilateral T0.

[0062] The aforementioned transport structure 20 allows for a significant reduction in transport dimensions while reliably protecting the internal fire-resistant lining 60 from damage. Furthermore, the transport structure 20 is not only easy to form but also very convenient to disassemble, thus facilitating subsequent assembly.

[0063] In one embodiment, each docking module 1 may further include a bottom wall 3 and / or a top wall 4. The bottom wall 3 is connected to the L-shaped bottom edge 23 of the L-shaped wall 2 of the corresponding docking module 1 in the longitudinal direction H1, and is configured to form part of the bottom wall 13 of the box furnace 10. The top wall 4 is connected to the L-shaped top edge 24 of the L-shaped wall 2 of the corresponding docking module 1 in the longitudinal direction H1, and is configured to form part of the top wall 14 of the box furnace 10.

[0064] The aforementioned pair of docking modules 1a and 1c are staggered in the longitudinal direction H1, such that the bottom end walls 3 of the aforementioned pair of docking modules 1a and 1c are separated from each other by a predetermined distance, and / or, the top end walls 4 of the aforementioned pair of docking modules 1a and 1c are separated from each other by a predetermined distance. Figure 4 The specified distance dt is, for example, 200mm or more, further 300mm or even 500mm.

[0065] The above arrangement, while making the structure compact, can protect the fire-resistant lining 60 from damage. As mentioned earlier, the closed quadrilateral T0 can be rectangular. The cross-sections of the L-shaped walls 2 of the aforementioned pair of docking modules 1a and 1c can be identical in size.

[0066] See also Figure 3AThe temporary connection structure 7 includes two angle steels 72, and each L-shaped wall 2 has a connecting post 61 on the outer side of both ends 28. The two sides 721 of each angle steel 72 are connected to the connecting post 61 at the junction P1 of the aforementioned pair of L-shaped walls 2a and 2c by fasteners 73, thereby connecting the aforementioned pair of L-shaped walls 2a and 2c to each other through the two angle steels 72 and the fasteners 73.

[0067] It's important to understand here that the use of the concrete term "angle steel" in the text doesn't necessarily limit the material of this component to steel. Rather, using industry-standard terminology helps to more clearly express the structural characteristics of the component. This doesn't preclude the use of other materials, especially if sufficient strength is available. Similar expressions include the previously mentioned steel structures.

[0068] This invention also provides a method M0 for manufacturing a box furnace 10, which can be combined with reference to [other methods]. Figures 1A to 7 As will be seen from the following description, "manufacturing" here may include one or more stages from manufacturing parts in the workshop to the final assembly on site. The box furnace 10 to be manufactured has four box sidewalls 11 extending along the longitudinal direction H1 and forming a closed quadrilateral T0 in the circumferential direction C0.

[0069] The manufacturing method M0 may include preparation step S1 and assembly step S2.

[0070] In preparation step S1, four docking modules 1 are prepared, such that each docking module 1 includes an L-shaped wall 2 that is configured to extend along the longitudinal direction H1 and has an L-shaped cross-section, and the four L-shaped walls 2 belonging to the four docking modules 1 are prepared to form the four corners cut from a closed quadrilateral T0. The preparation step can be completed, for example, in a manufacturing workshop.

[0071] In assembly step S2, the four L-shaped walls 2 are connected in pairs along the circumferential direction C0 through the docking structure 6, thereby forming a closed quadrilateral T0, and thus obtaining the box furnace 10. That is, the two adjacent straight wall segments 21 and 22 belonging to two adjacent L-shaped walls 2 are connected through the docking structure 6, thereby forming one of the four box side walls 11. Assembly step S2 can be performed at the user's site, for example.

[0072] This assembly method makes it possible to reduce the size during transportation while protecting the refractory lining.

[0073] Similar to what was mentioned earlier, in preparation step S1, each docking module 1 may also include a bottom wall 3 and / or a top wall 4. The bottom wall 3 is connected to the L-shaped bottom edge 23 of the L-shaped wall 2 of the corresponding docking module 1 along the longitudinal direction H1. The top wall 4 is connected to the L-shaped top edge 24 of the L-shaped wall 2 of the corresponding docking module 1 along the longitudinal direction H1.

[0074] Correspondingly, in assembly step S2, the bottom walls 3 of the four docking modules 1 can be spliced ​​together to form the bottom wall 13 of the box furnace 10, and the top walls 4 of the four docking modules 1 can be spliced ​​together to form the top wall 14 of the box furnace 10.

[0075] See also Figure 5 Taking the bottom wall 3 spliced ​​together to form the bottom wall 13 of the box as an example, a splicing structure 8 similar to the docking structure 6 can also be used to complete the task. Figure 5 In the middle, corresponding to the four bottom end walls 3, four splicing structures 8 are shown, respectively corresponding to Figure 5 The four arms of the cross are shown in the figure. The splicing structure 8 includes splicing beams 81 disposed on the outer sides 31 of the two bottom end walls 3 (e.g., 3a, 3b) to be spliced, and the two splicing beams 81 can be connected by through holes in fasteners 83. Figure 5 Along the extension direction of the splicing crossbeam 81, multiple through holes are provided, and corresponding fasteners 83 are used for connection. This can also be applied to the fasteners 63 of the aforementioned mating structure 6. A gasket similar to the aforementioned gasket 62 can also be sandwiched between the two splicing crossbeams 81, and welding similar to the aforementioned solder 64 can be used on the outside.

[0076] Similar to what was mentioned earlier, in preparation step S1, four docking modules 1 with identical cross-sectional dimensions of the L-shaped wall 2 can be prepared. The closed quadrilateral T0 can be rectangular.

[0077] In preparation step S1, docking columns 61 are provided on the outer sides of both ends 28 of each L-shaped wall 2.

[0078] In assembly step S2, the ends 28 of two adjacent L-shaped walls 2 (e.g., 2a, 2b) are joined together, so that the two mating surfaces 611 of the mating posts 61 belonging to the two adjacent L-shaped walls 2a, 2b are facing each other. A gasket 62 is sandwiched between the two mating surfaces 611. A fastener 63 passes through the two mating surfaces 611 and the gasket 62, thereby connecting the two mating posts 61 and the two adjacent L-shaped walls 2a, 2b. Then, welding is performed on the outside of the gasket 62, so that the two mating surfaces 611 and the two adjacent L-shaped walls 2a, 2b are fixedly connected.

[0079] In manufacturing method M0, preparation step S1 can be performed in a first location, and assembly step S2 can be performed in a second location. As mentioned earlier, the first location is, for example, a manufacturing workshop, and the second location is, for example, the user's site.

[0080] It is understood that the terms "first" and "second" in this document are used for descriptive purposes only and do not refer to limitations on chronological order, quantity, or importance. They should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated, but are merely used to distinguish one technical feature from another in this technical solution. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "multiple" means two or more (i.e., more than two), unless otherwise explicitly specified. Similarly, qualifiers such as "one" appearing in this document do not refer to limitations on quantity, but rather describe technical features not previously mentioned. Likewise, unless a noun is modified by a specific quantifier, it should be considered to include both singular and plural forms; the technical solution may include either a singular or plural number of the technical feature. Similarly, modifiers such as "approximately" or "about" preceding numerals in this document generally include the number itself, and their specific meaning should be understood in conjunction with the context.

[0081] In the first location, each pair of docking modules 1 (e.g., 1a and 1c, 1b and 1d) from the four docking modules 1 prepared in preparation step S1 is paired to assemble a transport structure 20 for two box furnaces 10, and then the transport structure 20 is transported to the second location. In other words, the manufacturing method M0 also includes a transport step S12, in which the transport structure 20 is transported.

[0082] In the second location, prior to assembly step S2, disassembly step S14 is performed to disassemble the docking modules 1 from the two transport structures 20, thereby obtaining the four docking modules 1 used in assembly step S2. Disassembly step S14 is also about to... Figure 3A For example, the angle steel 72 in the temporary connection structure 7 is removed, thereby separating the pair of docking modules 1, such as 1a and 1c, that make up the transport structure 20.

[0083] It is understood that when a method described in the text includes several operations, such as steps, the order of execution of the operations is not limited unless otherwise specified. If it is specifically stated that the second operation is performed after the first operation, or a similar description is used, it only indicates the order of execution of the first and second operations, and does not exclude the possibility of performing a third operation between the first and second operations, nor does it exclude the possibility of performing a third operation before or after the first operation. For example, as described above, in assembly step S2, the four L-shaped walls 2 are connected in pairs to form a closed quadrilateral T0, thereby obtaining the box furnace 10. However, in reality, in order to obtain the box furnace 10, in addition to connecting the L-shaped walls 2, many other operations are required, such as splicing the bottom wall 3 and the top wall 4.

[0084] As mentioned earlier, each transport structure 20 may include a pair of docking modules 1 (e.g., 1a, 1c), with docking posts 61 provided on the outer sides of both ends 28 of the L-shaped wall 2 of each docking module 1. The pair of L-shaped walls 2 (e.g., 2a, 2c) belonging to the aforementioned pair of docking modules 1 connect to form another quadrilateral T1, smaller than the closed quadrilateral T0. The two L-shaped walls 2 are configured to respectively form two of the four corners cut from the closed quadrilateral T0, for example, two corners on the diagonal. Each docking module 1 may also include two angle steels 72, and in the transport structure 20, the two sides 721 of each angle steel 72 are respectively connected to the docking posts 61 at the connection point P1 of the aforementioned pair of L-shaped walls 2a, 2c by fasteners 73.

[0085] Assembly step S2 is preferably performed with the box furnace 10 in a horizontal position. The manufacturing method M0 may subsequently include a flipping step S3. That is, see [link to documentation]. Figure 7 For example, by hoisting, the horizontally lying box furnace 10 can be flipped to an upright position, thus making the longitudinal direction H1 extend horizontally relative to the ground. Figure 7 (bottom right corner) switch to vertical extension ( Figure 7 (Top left corner). Assembling in a horizontal position is more convenient and safer.

[0086] As an example of a furnace or even a container, the structure and manufacturing method of the aforementioned box furnace 10 can be applied to containers. As can be seen from the preceding description, the above structure and method are particularly suitable for containers that require special material layers inside, such as the aforementioned refractory lining, and therefore require special protection during transportation.

[0087] Therefore, the present invention also provides a method for manufacturing a container, wherein the container to be manufactured has N side walls (corresponding to the four box side walls 11 in the figure) extending along the longitudinal direction H1 and forming a closed shape (corresponding to the closed quadrilateral T0 in the figure) on the circumferential direction C0.

[0088] The manufacturing method includes a preparation step S1 and an assembly step S2. In the preparation step S1, N docking modules 1 are prepared, such that each docking module 1 includes a wall segment extending along the longitudinal direction H1 (corresponding to the L-shaped wall 2 in the figure). The N wall segments belonging to the aforementioned N docking modules 1 are prepared to form N segments cut from a closed shape in the circumferential direction C0. The aforementioned N wall segments are arranged to be divided into several groups (corresponding to groups 1a, 1c and 1b, 1d in the figure). At least two wall segments in each group (corresponding to the L-shaped walls 1a and 1c in the figure) are arranged to be able to connect with each other to form another closed shape that is smaller than the closed shape (corresponding to another quadrilateral T1 in the figure).

[0089] In assembly step S2, the aforementioned N wall segments are connected in pairs along the circumferential direction C0 through the docking structure 6, thereby forming the aforementioned closed shape and thus obtaining the container.

[0090] In particular, the aforementioned closed shape can be centrally symmetrical, such as a circle, rhombus, or regular hexagon. This allows two segments located diagonally opposite the center to connect with each other, such as... Figure 2B Two L-shaped walls, 2a and 2c, are located on the diagonal.

[0091] Furthermore, in the above manufacturing method, preparation step S1 can be performed in the first location, and assembly step S2 can be performed in the second location. The aforementioned N segments can be formed by dividing the aforementioned closed shape into N equal parts in the circumferential direction.

[0092] In the first location, every two docking modules 1 of the N docking modules 1 prepared in preparation step S1 are paired to assemble M transport structures, such as 20, and then the transport structures 20 are transported to the second location. Wherein, M = N / 2.

[0093] In the second location, before assembly step S2, disassembly step S14 is performed to disassemble docking modules 1 from the M transport structures 20, thereby obtaining N docking modules 1 used in assembly step S2.

[0094] Each transport structure 20 includes a pair of docking modules 1, the wall sections of which are connected to each other by a temporary connection structure, such as 7, to form a closed shape compared to the aforementioned.

[0095] The aforementioned structure and method, through ingenious deconstruction, can significantly reduce the size of the intermediate structure, i.e., the transport structure, during transportation, thus facilitating transport operations. Simultaneously, it ensures reliable protection for special internal materials. Overall, it solves the problem of size-based transportation limitations without increasing excessive packaging costs, while minimizing on-site installation workload.

[0096] Unless otherwise clearly indicated, each aspect or embodiment defined herein may be combined with any other aspect or embodiment. In particular, any feature indicated as preferred or advantageous may be combined with any other feature indicated as preferred or advantageous.

[0097] The foregoing description in this specification represents only preferred embodiments of the present invention. These embodiments are merely illustrative of the technical solutions of the present invention and are not intended to limit the scope of the invention. Any technical solutions that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation based on the concept of the present invention should be within the scope of the present invention.
