Description

Technical Field

[0001] The present application relates to the field of sintering equipment, and in particular to a sintering furnace. Background Art

[0002] The thermal insulation layer is an important component of the sintering furnace, which is used to reduce the heat loss in the furnace and improve the sintering efficiency. The thermal insulation layer is usually arranged on the supporting structure on the inner side of the sintering furnace body. The existing support structure of the thermal insulation layer usually includes at least two supporting units, each supporting unit includes a horizontal plate and a vertical plate welded to the inner side of the furnace body in the horizontal and vertical directions respectively. The horizontal plate and the vertical plate are welded and fixed to each other, and together support the thermal insulation layer in the furnace body. Although this support structure can realize the support function of the thermal insulation layer, the following problems exist in actual use: the welding points between the horizontal plate and the vertical plate, and the welding points between the vertical plate and the furnace body are stress concentration areas. After multiple high-temperature sintering, they are prone to cracking, affecting their own service life, and then affecting the support effect of the thermal insulation layer and the normal operation of the sintering furnace. After cracking, the support structure needs to be reworked and re-welded, and the process of disassembling the thermal insulation layer is relatively complicated, which causes a lot of unnecessary time and maintenance costs.

[0003] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field. Utility Model Content

[0004] (1) Technical problems solved

[0005] An embodiment of the present application provides a sintering furnace that can solve the problem in the prior art of how to reduce cracking of the insulation layer support structure at the welding points and extend its service life.

[0006] (2) Technical solution

[0007] To solve the above technical problems, this application provides the following technical solutions:

[0008] A sintering furnace is provided, comprising: a furnace body, a folding plate and a baffle;

[0009] The folding plate is used to support the insulation layer in the furnace body, and includes a first supporting portion and a second supporting portion formed integrally, one end of the first supporting portion is connected to the second supporting portion, and the other end is supported on the inner side of the furnace body, and the bottom of the second supporting portion is welded to the inner side of the furnace body;

[0010] The baffle is fixedly connected to the inner side of the furnace body and is connected to the second supporting portion by screws.

[0011] In some embodiments, the first support portion is disposed horizontally, and the second support portion is disposed vertically.

[0012] In some embodiments, the baffle is parallel to the second supporting portion.

[0013] In some embodiments, the bottom of the baffle is welded to the inner side of the furnace body.

[0014] In some embodiments, the other end of the first supporting portion is welded to the inner side of the furnace body.

[0015] In some embodiments, the folding plates and baffles are evenly arranged into at least two groups in the length direction of the furnace body.

[0016] In some embodiments, the sintering furnace further includes a reinforcing plate, which is fixedly connected to the first supporting portion of each group of the folding plates and is located on top of the first supporting portion and the second supporting portion.

[0017] In some embodiments, the folding plates and baffles are symmetrically arranged in at least two groups with the radial plane in the vertical direction of the furnace body as the center.

[0018] (3) Beneficial effects

[0019] Compared with the prior art, the technical solutions provided in the embodiments of the present application have at least the following beneficial effects:

[0020] The sintering furnace of the present application uses folded plates to support the insulation layer within the furnace body, and uses baffles to reinforce the structural strength of the folded plates, thereby extending its service life. Specifically, because the first and second support parts are designed as an integrated structure, the number of weld points is reduced compared to the traditional connection method of horizontal and vertical plates that requires additional welding. This improvement significantly reduces the risk of cracking at the connection, thereby improving the reliability and durability of the structure. At the same time, the second support part is not only welded to the furnace body, but also connected to the baffle via screws. This dual fixing method allows the second support part to better distribute the applied force to the baffle, thereby enhancing the load-bearing capacity of the structure. When subjected to the same load, this structure can more effectively reduce the risk of cracking at the connection between the vertical connecting plate and the furnace body compared to the traditional vertical plate fixing method. By reducing the risk of cracking at the weld points, the support structure of the present application reduces the need for rework and repairs caused by cracking. This not only reduces the various maintenance costs required, but also improves production efficiency and ensures the continuous and stable operation of the sintering furnace.

DETAILED DESCRIPTION

[0029] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See Figure 1 As shown, Figure 1This is a schematic diagram of an existing insulation layer support structure. The existing insulation layer support structure typically includes at least two support units 100. Each support unit 100 includes a horizontal plate 110 and a vertical plate 120 welded to the inner side of the furnace body in the horizontal and vertical directions, respectively. The horizontal plate 110 and the vertical plate 120 are welded and fixed to each other, and together support the insulation layer within the furnace body. Although this support structure can support the insulation layer, it suffers from the following problems during actual use: the welding points between the horizontal plate 110 and the vertical plate 120, as well as the welding points between the vertical plate 120 and the furnace body 1, are stress concentration areas and are prone to cracking after multiple high-temperature sintering cycles, which affects their service life.

[0032] In order to solve the above technical problems, this embodiment provides a sintering furnace, see Figures 2 to 5 As shown, Figure 2 is a schematic diagram of a sintering furnace in an embodiment of the present application, Figure 3 yes Figure 2 Schematic diagram of area A in the middle. Figure 4 yes Figure 2 The cross-sectional view of section B, Figure 5 yes Figure 2 Cross-sectional view of section C.

[0033] The sintering furnace of this embodiment includes: a furnace body 1 , a folding plate 2 and a baffle 3 .

[0034] The furnace body 1 is the main body of the sintering furnace, which is used to accommodate the insulation layer and the material to be sintered, and provide the necessary sintering environment.

[0035] The folded plate 2 is used to support the insulation layer in the furnace body and includes an integrally formed first support portion 21 and a second support portion 22. One end of the first support portion 21 is connected to the second support portion 22, and the other end is supported on the inner side of the furnace body 1. The bottom of the second support portion 22 is welded to the inner side of the furnace body 1.

[0036] The baffle 3 is fixedly connected to the inner side of the furnace body 1 and is screwed to the second support portion 22. The main function of the baffle 3 is to further strengthen the support structure, disperse the force exerted on the folding plate 2, and prevent the insulation layer from shifting in the horizontal direction.

[0037] The sintering furnace of the above technical solution supports the insulation layer in the furnace body through the folding plate 2, and strengthens the structural strength of the folding plate 2 through the baffle 3, thereby extending the service life. Specifically, the folding plate 2 supports the insulation layer in the furnace body through the first support part 21 and the second support part 22. Since the first support part 21 and the second support part 22 are integrally formed, compared with the traditional horizontal plate and vertical plate, the welding point between the two is eliminated, which can significantly reduce the risk of cracking at the connection. At the same time, the second support part 22 is connected to the baffle 3 by screws on the basis of being welded to the furnace body 1, which can disperse the force it is subjected to to the baffle 3. Compared with the traditional vertical plate that is only fixed to the furnace body 1 by welding, it can withstand a greater load and reduce the risk of cracking at the connection between the vertical connecting plate and the furnace body 1 under the same load. It can be seen that the sintering furnace of the above technical solution can reduce the cracking at the welding point, thereby extending the service life, reducing the rework caused by cracking, and reducing the various costs required for maintenance.

[0038] For example, see Figure 3 As shown, the first support portion 21 is arranged horizontally, and the second support portion 22 is arranged vertically. The first support portion 21 is arranged horizontally to directly support the insulation layer within the furnace body, ensuring that the insulation layer can stably cover the inner side of the furnace body 1 and reduce heat loss. The second support portion 22 is arranged vertically, and its bottom is fixedly connected to the inner side of the furnace body 1 by welding, forming a stable support structure. This design not only improves the strength of the support structure, but also effectively prevents the insulation layer from falling off and deforming.

[0039] In order to facilitate the connection of the baffle 3 and the second support portion 22 by screws, see Figure 3 As shown, the baffle 3 is parallel to the second support portion 22 and is respectively provided with horizontally arranged screw holes for screw insertion and installation.

[0040] In one embodiment of the above-mentioned fixed connection between the baffle 3 and the furnace body 1, see Figure 3 As shown, the bottom of the baffle 3 is welded to the inner side of the furnace body 1 .

[0041] In other embodiments in which the baffle 3 is fixedly connected to the furnace body 1 , the baffle 3 and the furnace body 1 are integrally formed or fixedly connected by bolts.

[0042] The first support portion 21 can be supported on the inner side of the furnace body 1 by welding or connecting the other end of the first support portion 21 to the inner side of the furnace body 1. It is understandable that the first support portion 21 can also be directly mounted on the inner side of the furnace body 1.

[0043] For example, see Figure 4 and Figure 5As shown, the folding plates 2 and baffles 3 are evenly arranged in at least two groups along the length of the furnace body 1. This arrangement ensures that the insulation layer is evenly supported throughout the interior of the furnace body 1. This even arrangement also improves the overall stability of the support structure and further reduces cracking at weld points.

[0044] In order to further improve the strength and stability of the support structure and the support effect of the insulation layer, refer to Figure 3 and Figure 5 As shown, the sintering furnace also includes a reinforcing plate 4, which is fixedly connected to the first support portion 21 of each group of folding plates 2 by welding, and is located on top of the first support portion 21 and the second support portion 22. The reinforcing plate 4 can not only improve the integrity of each group of folding plates 2, but also evenly distribute the local force to each folding plate 2 when the individual folding plates 2 are subjected to greater force, thereby reducing the load on the individual folding plates 2, and further reducing the risk of cracking of the support structure at the welding points.

[0045] For example, see Figure 3 and Figure 5 As shown, at least two sets of folded plates 2 and baffles 3 are symmetrically arranged around a vertical radial plane of the furnace body 1. This symmetrical design not only improves the symmetry of the support structure but also provides uniform vertical support for the insulation layer, further enhancing stability. Furthermore, the symmetrical support structure evenly distributes the forces acting on the insulation layer, reducing the risk of cracking of individual folded plates 2 due to excessive force.

[0046] The above description is merely an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
