Description

Technical Field

[0001] This utility model relates to the field of refractory materials technology, specifically to a hanging plate installation structure for a waste incineration power plant. Background Technology

[0002] Waste-to-energy incineration is the most effective way to achieve the harmlessness, reduction, resource recovery, and sustainable development of waste, and it is also the most widely used method in countries around the world for efficient and clean waste treatment. During the waste incineration process, the refractory material lining the incinerator not only protects the main metal structure from corrosion and damage by the complex internal atmosphere at high temperatures, but also plays a crucial role in extracting the waste heat generated from waste incineration for power generation.

[0003] Currently, hanging panels are the primary material used for lining waste incinerators. As a dense, shaped product, hanging panels offer significant advantages over unshaped products, including higher bulk density, higher strength, better thermal conductivity, superior corrosion resistance, and stronger thermal shock resistance. These characteristics result in a longer service life and higher thermal efficiency, effectively protecting the metal structure of the waste incinerator from high-temperature corrosion, making them an ideal material for long-life, high-efficiency waste-to-energy incinerator linings. During construction, the hanging panels are suspended from hooks between water-cooled metal pipes via hanging openings, and then castable refractory is poured into the gaps between the water pipe walls and the hanging panels.

[0004] Existing mounting plates mainly rely on the cooperation of hooks and mounting openings to connect with water-cooled metal pipes. However, this connection method easily creates cavities between the water-cooled metal pipes and the mounting plate when pouring castable refractory into the gaps. To solve this problem, a refractory mounting plate for waste incineration power plants has emerged in the prior art, as detailed in reference 1.

[0005] Reference 1: Chinese patent document with patent publication number CN 212673236 U.

[0006] The refractory hanging plate for a waste incineration power plant disclosed in Reference 1 has arc-shaped grooves on its body that precisely match the water-cooling pipes. A gap is left between the inner diameter surface of each arc-shaped groove and the outer wall surface of the corresponding water-cooling pipe for filling with castable refractory. A hanging opening is provided between two adjacent arc-shaped grooves, and a hook matching the hanging opening is provided on the water-cooling pipe at the corresponding position. In addition, the body also has a through hole communicating with the hanging opening, the function of which is to exhaust air. One end of the through hole connects to the end of the hanging opening, and the other end extends beyond the upper end surface of the body. By providing the through hole, gas can be guided out, reducing the possibility of cavity formation to a certain extent, thereby ensuring that the hanging plate as a whole has high thermal conductivity and effectively preventing the occurrence of localized high temperatures.

[0007] However, the through-hole design described in Reference 1 has certain drawbacks. Due to the location of the through-hole, it is easily blocked by the hook, making it difficult for air to escape. At the same time, this design cannot effectively maintain the distance between the mounting plate and the water-cooling pipe, which makes it inconvenient for workers to perform casting pouring operations. Utility Model Content

[0008] The purpose of this invention is to solve the problem in the prior art that the filler material cannot be easily poured in and filled with high quality during the installation of the mounting plate, and to provide a mounting plate installation structure for a waste incineration power plant.

[0009] To address the shortcomings of the aforementioned technical problems, the present invention adopts the following technical solution: a mounting structure for a waste incineration power plant, which has a hook on a water-cooling pipe and a hanging opening on the mounting plate. The end of the hook facing away from the water-cooling pipe is provided with a deformation part, and the hanging opening is provided with a limiting groove.

[0010] The limiting groove is an inclined upward slot with a gradually decreasing space. The limiting groove can restrict the deformation part so that the hook cannot be fully engaged in the hanging opening, maintaining the distance between the hanging plate and the water cooling pipe. Moreover, after the deformation part is deformed by force, the limiting groove can make the hanging opening and the hook fully engage, reducing the distance between the hanging plate and the water cooling pipe.

[0011] As a further optimization of the mounting structure of the hanging plate for the waste incineration power plant of this utility model: both the hook and the hanging opening are L-shaped, the horizontal section of the hook is the support part, the horizontal section of the hanging opening is the support part, and the support parts are fitted together with a gap.

[0012] As a further optimization of the mounting structure of the hanging plate for the waste incineration power plant of this utility model: both the hook and the hanging opening are obtuse-angled triangles that are inclined upwards, the deformation part is located at the upward inclined end of the hook, and the limiting groove is located at the upward inclined end of the hanging opening.

[0013] As a further optimization of the mounting structure of the hanging plate for the waste incineration power plant of this utility model: the deformable part is the end of the hook away from the water cooling pipe, and a deformation groove is opened at the end of the hook away from the water cooling pipe.

[0014] As a further optimization of the mounting structure of the hanging plate for the waste incineration power plant of this utility model: the deformable part is the end of the hook away from the water cooling pipe, and an elastic layer is provided on the outer periphery of the end of the hook away from the water cooling pipe. After the elastic layer deforms, the hook can be fully engaged in the limiting groove.

[0015] As a further optimization of the mounting structure of the hanging plate for the waste incineration power plant of this utility model: auxiliary blocks are evenly provided on the side of the hook facing the water cooling pipe.

[0016] As a further optimization of the mounting structure of the hanging plate for a waste incineration power plant of this utility model: the auxiliary block is made of elastic material, so as to assist the top pressure water cooling pipe in positioning the hanging plate during the process of hooking into the hanging port.

[0017] As a further optimization of the mounting structure of the hanging plate for a waste incineration power plant of this utility model: the auxiliary block is integrally formed with the hanging plate, so as to assist in positioning the hanging plate by pressing the water cooling pipe when the hook is fully connected to the hanging opening.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention utilizes a limiting groove within the hanging opening to engage with the deformable portion of the hook at the end opposite the water-cooling pipe, maintaining a certain distance between the hanging plate and the hook. This greatly facilitates the installation of filler material, allowing workers to easily insert it. After filling, the worker can tap the hanging plate to fully insert the deformable portion into the limiting groove, achieving complete connection between the hook and the hanging opening under this external force. At this point, the hanging plate tilts, applying pressure to the filler material. This tilting and pressing method not only effectively ensures the stability of the connection between the hanging plate, filler material, and water-cooling pipe but also significantly reduces the probability of cavities within the filler material. The reduction in cavities greatly improves the overall thermal conductivity of the hanging plate, enabling more efficient heat transfer and effectively preventing localized high temperatures. This improves the convenience of filling the hanging plate during installation and ensures high-quality completion of subsequent filling work. Attached Figure Description

[0026] To better understand this utility model, the following embodiments further illustrate the content of this utility model, but the content of this utility model is not limited to the following embodiments.

[0027] <Example 1>

[0028] like Figure 1 and Figure 2 As shown, a mounting structure for a waste incineration power plant is disclosed. Similar to existing technologies, this structure includes hooks 3 mounted on water-cooling pipes 1 and mounting plates 2 with hanging openings 4. The hooks 3 and hanging openings 4 can be connected to each other, providing convenience for workers to subsequently fill the material.

[0029] The significant difference between this structure and existing technologies lies in the unique design of the hook 3. The hook 3 consists of a support part 301 securely connected to the water-cooling pipe 1, and a deformation part 302 located on the side of the support part 301 facing away from the water-cooling pipe 1. The deformation part 302 and the support part 301 form an L-shaped configuration. Specifically, the limiting groove 402 is inclined, and its internal space gradually narrows from one end to the other. The limiting groove 402 and the insertion groove 401 also form an L-shaped configuration. The deformation part 302 can pass through the insertion groove 401 included in the hanging opening 4, and is thus restricted by the flared position of the limiting groove 402. Simultaneously, the hook 3 only partially enters the hanging opening 4. This ensures a certain gap is maintained between the hanging plate 2 and the water-cooling pipe 1, allowing workers to easily fill the gap between the water-cooling pipe 1 and the hanging plate 2 with filling material.

[0030] After the operator completes the filling of the filler material between the water-cooling pipe 1 and the mounting plate 2, they simply tap the surface of the mounting plate 2. At this time, the limiting groove 402 will exert a squeezing effect on the deformable part 302, causing the deformable part 302 to deform and penetrate deeper into the limiting groove 402. Immediately afterwards, the hook 3 will fully enter the hanging opening 4. Through the mutual squeezing between the limiting groove 402 and the deformable part 302, the stability of the mounting plate 2 connected to the water-cooling pipe 1 is effectively ensured. Moreover, during the tapping of the mounting plate 2, the mounting plate 2 will tilt closer to the water-cooling pipe 1. This action will cause the mounting plate 2 to squeeze the filler material, thereby expelling the gas inside the filler material, greatly reducing the possibility of cavities forming inside the filler material, and further enhancing the tightness of the connection between the mounting plate 2 and the water-cooling pipe 1 and the filler material.

[0031] There are two specific forms of the deformation part 302. The first form is where the deformation part 302 is the end of the hook 3 facing away from the water-cooling pipe 1 where a deformation groove 303 is formed. When the mounting plate 2 is struck, under the constraint of the limiting groove 402, the deformation groove 303 will squeeze the deformation part 302, causing the hook 3 to fully engage with the mounting opening 4. This process will drive the mounting plate 2 to tilt closer to the water-cooling pipe 1, thereby squeezing the filler material, expelling the gas inside the filler material, reducing the probability of cavities forming inside the filler material, and significantly improving the fit between the mounting plate 2 and the water-cooling pipe 1 as well as the tightness of the connection with the filler material. The second form is where the deformation part 302 can also be the end of the hook 3 facing away from the water-cooling pipe 1 with an elastic layer on its outer periphery. Specifically, the elastic layer is made of elastic rubber, and the supporting part of the hook 3 is smaller than the minimum space at the top of the limiting groove 402. In this case, the elastic layer can deform under the squeezing action of the limiting groove 402, so that the hook 3 can be fully inserted into the hanging opening 4, thus successfully completing the connection.

[0032] like Figure 5 As shown, auxiliary blocks 5 are evenly distributed on the inner wall of the mounting plate 2, corresponding to the positions of the water-cooling pipe 1. These auxiliary blocks 5 can be integrally formed with the mounting plate 2, and can significantly increase the amount of filler material that is blocked and retained when the filler material is poured into the gap between the mounting plate 2 and the water-cooling pipe 1. This characteristic effectively enhances the filling effect of the filler material, providing a more solid guarantee for the stability of the subsequent connection between the mounting plate 2 and the water-cooling pipe 1. When the hook 3 and the hanging opening 4 are fully aligned, the auxiliary blocks 5 will fit tightly against the surface of the water-cooling pipe 1. This tight fit further enhances the connection tightness between the mounting plate 2 and the water-cooling pipe 1, making the entire structure more stable and reliable during operation, and effectively reducing various problems that may be caused by loose connections. The auxiliary blocks 5 can also be made of elastic material. The auxiliary blocks 5 made of elastic material not only have the functions of increasing the amount of filler material retained and enhancing the connection tightness, but also play a limiting role on the deformation part 302 of the hook 3 at the flared end of the limiting groove 402. When a certain distance is maintained between the mounting plate 2 and the water-cooling pipe 1, the elastic auxiliary block 5 can cleverly assist in pressing down on the water-cooling pipe 1. Through this pressing action, the vertical stability of the mounting plate 2 is effectively maintained, and the swaying or displacement of the mounting plate 2 during operation is avoided, thereby further improving the performance and reliability of the entire mounting plate 2 installation structure.

[0033] like Figure 1 and Figure 2As shown, in actual use, the mounting plate 2 is first accurately hung on the water-cooling pipe 1 using the cooperation of the mounting opening 4 and the hook 3. At this time, the limiting groove 402 of the mounting opening 4 cooperates with the deformable part 302 of the hook 3, so that the hook 3 only partially enters the mounting opening 4. At the same time, the auxiliary block 5 set on the inner wall of the mounting plate 2 can help maintain the vertical stability of the mounting plate 2, laying a good foundation for subsequent operations. Subsequently, the staff can easily pour the filler into the gap between the water-cooling pipe 1 and the mounting plate 2. After the filler is poured in, the staff taps the mounting plate 2 to cause the deformable part 302 to deform and penetrate into the limiting groove 402, realizing the complete connection between the hook 3 and the mounting opening 4. This process causes the mounting plate 2 to tilt closer to the water-cooling pipe 1 and squeeze the filler, thereby expelling the air in the filler and significantly improving the tightness of the filler connection between the water-cooling pipe 1 and the mounting plate 2, ensuring the stability and reliability of the entire installation structure.

[0034] <Example 2>

[0035] like Figure 3 and Figure 4 As shown, the structure of this embodiment is basically the same as that of Embodiment 1. The difference is that the vertical cross-sections of the hook 3 and the hanging opening 4 are both obtuse-angled triangles tilted upwards. The upward-tilting apex of the hook 3 is the deformation part 302, and the upward-tilting apex of the hanging opening 4 is the limiting groove. The deformation part 302 can be precisely positioned at the flared position of the limiting groove 402. Simultaneously, the hook 3 only partially enters the hanging opening 4. This ensures a certain gap between the hanging plate 2 and the water-cooling pipe 1, allowing workers to easily fill the gap between the water-cooling pipe 1 and the hanging plate 2 with filling material.

[0036] After the operator completes the filling of the filler material between the water-cooling pipe 1 and the mounting plate 2, they simply tap the surface of the mounting plate 2. At this time, the limiting groove 402 will exert a squeezing effect on the deformable part 302, causing the deformable part 302 to deform and penetrate deeper into the limiting groove 402. Immediately afterwards, the hook 3 will fully enter the hanging opening 4. Through the mutual squeezing between the limiting groove 402 and the deformable part 302, the stability of the mounting plate 2 connected to the water-cooling pipe 1 is effectively ensured. Moreover, during the tapping of the mounting plate 2, the mounting plate 2 will tilt closer to the water-cooling pipe 1. This action will cause the mounting plate 2 to squeeze the filler material, thereby expelling the gas inside the filler material, greatly reducing the possibility of cavities forming inside the filler material, and further enhancing the tightness of the connection between the mounting plate 2 and the water-cooling pipe 1 and the filler material.

It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this utility model.
