Abstract
Description
Technical Field
[0001] This utility model relates to the field of graphitization furnace technology, and in particular to a prefabricated composite graphitization furnace wall component. Background Technology
[0002] The size of a precast component is closely related to its structural strength. If a precast component is heated unevenly during use, inconsistent shrinkage will cause stress and lead to cracks.
[0003] Existing precast furnace wall components, such as the one disclosed in CN220356084U, can separate the surface of the baffle from the expanded polyethylene foam layer. This prevents the insulation layer and the expanded polyethylene foam layer from compressing the concrete wall panel during expansion, thus preventing the concrete wall panel from cracking due to compression. This allows the concrete wall panel to effectively insulate the graphitization furnace. However, the fixed connection between the main structures not only increases the difficulty of filling the material within the precast furnace wall component but also leads to structural instability. The lack of sufficient stress support points significantly reduces the structural strength, seriously affecting its safe use as a furnace wall component in graphitization furnaces. Utility Model Content
[0004] The purpose of this utility model is to solve the problem of the limited functionality and inconvenience of using prefabricated furnace walls with fixed structures in the prior art, and to propose a composite prefabricated furnace wall for graphitization furnaces.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A prefabricated composite graphitization furnace wall includes a concrete wall, a composite fiber reinforced board, a plastic steel fence, and a sealing plate. The concrete wall, composite fiber reinforced board, plastic steel fence, and sealing plate are arranged sequentially. A first connecting component is provided between the concrete wall and the composite fiber reinforced board to fix the two together. A second connecting component is provided on the concrete wall for fixing the plastic steel fence on the composite fiber reinforced board. The sealing plate is fixedly connected to the plastic steel fence by bolts.
[0007] Preferably, the concrete wall, composite fiber reinforced board, plastic steel fence and sealing plate are concentrically distributed.
[0008] Preferably, the first connecting assembly includes a square frame integrally connected to the concrete wall, and the concrete wall forms an inner cavity and an outer cavity through the square frame. A locking rod extending into the outer cavity is slidably fitted in the square frame. An extension rod is integrally connected to the composite fiber reinforced plate, and a locking through hole corresponding to the locking rod is opened in the extension rod. A guide rod is integrally connected to the concrete wall, and a strong spring and a movable washer for moving and pulling the locking rod are provided on the guide rod. A threaded rod is threadedly installed in the composite fiber reinforced plate and movably fitted on the guide rod.
[0009] Preferably, the strong spring is fixedly mounted on the guide rod, and the movable pad is slidably mounted on the guide rod. A traction link is connected between the movable pad and the locking rod by a pin.
[0010] Preferably, the second connecting component includes an L-shaped plug rotatably mounted on the composite fiber reinforced plate, and the bottom end of the plastic steel fence is provided with a corresponding slot for the L-shaped plug. The concrete wall is provided with a connected locking cavity and a locking hole, and a c-shaped clip for abutting and fixing the L-shaped plug is fitted in the locking cavity.
[0011] Preferably, a locking screw for fixing the shaped clip is threaded into the locking hole.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figures 1-6 A prefabricated composite graphitization furnace wall includes a concrete wall 1, a composite fiber reinforced board 2, a plastic steel fence 3, and a sealing plate 4. The concrete wall 1, composite fiber reinforced board 2, plastic steel fence 3, and sealing plate 4 are arranged sequentially. It should be noted that the sealing plate 4 has integrally extended lifting lugs on all four sides. The lifting lugs have countersunk holes corresponding to the plastic steel fence 3, and the plastic steel fence 3 also has threaded holes corresponding to the countersunk holes. The sealing plate 4 is fixedly connected to the furnace wall by tightening bolts extending from the countersunk holes to the threaded holes. On the PVC-U fence 3, it should be noted that by forming a locking rod 52 and an extension rod 53 with a warp and weft structure between the concrete wall 1 and the composite fiber reinforced board 2, more stress support structure is provided for both. By installing the PVC-U fence 3 on the composite fiber reinforced board 2 to form a cavity, and filling the space with expanded polyethylene foam material with heat insulation and pressure resistance, and then filling the outer position of the corresponding sealing plate 4 with 0.8-1㎡ of high temperature heat insulation board or high alumina fiberboard, the structural strength of the furnace wall prefabrication is improved.
[0024] A first connecting component 5 is provided between the concrete wall 1 and the composite fiber reinforced board 2 to fix them together. See the attached instruction manual for details. Figure 4 With appendix Figure 5 The first connecting component 5 includes a frame 51 integrally connected to the concrete wall 1, and the concrete wall 1 forms an inner cavity and an outer cavity through the frame 51. A locking rod 52 extending into the outer cavity is slidably fitted in the frame 51. An extension rod 53 is integrally connected to the composite fiber reinforced board 2. It should be noted that the number of locking rods 52 and extension rods 53 is equal, and can be set to 2-4 circumferentially equidistantly distributed to form a close-knit structure between the concrete wall 1 and the composite fiber reinforced board 2. A corresponding lock is provided in the extension rod 53. The locking through hole 54 of the locking rod 52 is integrally connected to the concrete wall 1. A guide rod 55 is integrally connected to the concrete wall 1. A strong spring 56 is fixedly connected to the guide rod 55 and a movable shim 57 is used to move the locking rod 52. A threaded rod 58 is threadedly installed in the composite fiber reinforced plate 2 and is movably fitted on the guide rod 55. By spiraling the threaded rod 58 on the composite fiber reinforced plate 2, the movable shim 57 moves linearly along the guide rod 55, thereby causing the locking rod 52 to expand radially until it is connected and fixed with the extension rod 53.
[0025] A second connecting component 6 is provided on the concrete wall 1 for fixing the plastic steel fence 3 to the composite fiber reinforced board 2. See the attached instruction manual for details. Figure 3 With appendix Figure 6 The second connecting component 6 includes an L-shaped plug 61 rotatably mounted on the composite fiber reinforced plate 2. The bottom end of the plastic steel fence 3 is inclined with a corresponding slot 62 for the L-shaped plug 61. The concrete wall 1 has a connected locking cavity 63 and a locking hole 64. The locking cavity 63 is fitted with a chamfered clip 65 for resisting and fixing the L-shaped plug 61. The number of the second connecting components 6 can be set to 2-4 sets, symmetrically arranged left and right and front and back, so as to facilitate reverse traction and fixation of the plastic steel fence 3 on the composite fiber reinforced plate 2.
[0026] The concrete wall 1, composite fiber reinforced board 2, plastic steel fence 3 and sealing board 4 are concentrically distributed and all adopt a square structure to facilitate mass production and assembly, providing convenience for the use of graphitization furnace walls.
[0027] A strong spring 56 is fixedly mounted on a guide rod 55, and a movable pad 57 is slidably mounted on a guide rod 55. A traction link 59 is pin-connected between the movable pad 57 and the locking rod 52. By applying pressure to the movable pad 57 on the guide rod 55, a unified drive is achieved for the circumferentially equidistant locking rods 52.
[0028] A locking screw for securing the inclined clip 65 is threaded into the locking hole 64 to ensure that the inclined clip 65 is securely positioned at one end of the L-shaped plug 61.
[0029] It should be noted that the specific models and specifications of the concrete wall 1, composite fiber reinforced board 2 and sealing board 4 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation methods adopt the existing technology in this field, so they will not be elaborated here.
[0030] The functional principle of this utility model can be explained through the following operation methods:
[0031] The composite fiber reinforced board 2 is pressed against the concrete wall 1, so that the extension rod 53 extends into the outer cavity. The threaded rod 58 is screwed into the composite fiber reinforced board 2. The threaded rod 58 goes deep along the guide rod 55 and applies pressure to the movable pad 57, which is elastically supported by the strong spring 56. The movable pad 57 supports the locking rod 52 through the extension rod 53 via the traction connecting rod 59. This improves the structural strength of the concrete wall 1 and the composite fiber reinforced board 2 while ensuring the fixed assembly connection between the two.
[0032] The plastic steel fence 3 is embedded in the composite fiber reinforced board 2. The incised clip 65 is installed in the clip cavity 63, and the incised clip 65 is locked and fixed by the locking screw in the locking hole 64, so that one end of the L-shaped plug 61 is fitted into the clip 62, thereby realizing the fixed connection of the plastic steel fence 3 on the composite fiber reinforced board 2.
[0033] By connecting the sealing plate 4 to the plastic steel fence 3, the lifting lugs are made to fit tightly against the plastic steel fence 3. The bolts in the four lifting lugs are tightened until they are in close contact with the threaded holes in the plastic steel fence 3, thereby fixing the sealing plate 4 to the plastic steel fence 3.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
