Description

Technical Field

[0001] This utility model relates to the field of water-cooled wall technology, and more specifically to a water-cooled fireplace wall reinforcement device. Background Technology

[0002] In modern industrial boilers, incinerators, and other thermal equipment, water-cooled walls are an important component of the furnace. They are constructed by welding together side-by-side water-cooled tubes and connecting fins, forming the heating surface and sealed furnace wall. Operating in a high-temperature flue gas environment for extended periods, water-cooled walls inevitably suffer from various adverse factors such as high-temperature corrosion, erosion, and thermal stress cycles.

[0003] Existing water-cooled fireplace walls typically employ various measures to enhance their strength. However, the overall rigidity of the water-cooled wall structure is sometimes insufficient to effectively resist impacts and vibrations within the furnace, potentially leading to deformation or even failure of the wall during long-term operation.

[0004] Therefore, it is necessary to propose a water-cooled fireplace wall reinforcement device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the problem that existing water-cooled fireplace walls, which typically employ various measures to enhance their strength, sometimes lack sufficient overall rigidity to effectively resist impacts and vibrations within the furnace, potentially leading to deformation or even failure of the furnace wall during long-term operation.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: A water-cooled fireplace wall reinforcement device includes a water-cooled fireplace wall connected by water-cooled wall fins. A trapezoidal block is fixedly connected between each pair of adjacent water-cooled wall fins. The trapezoidal block has an arc-shaped groove on the side facing the water-cooled wall fins to avoid water-cooling pipes. A baffle is inserted into the side of the water-cooled wall fins away from the water-cooled fireplace wall.

[0007] Furthermore, a convex groove is provided on the side of the trapezoidal block away from the water-cooled fireplace wall, and a convex strip is inserted into the convex groove. The baffle is fixedly connected to the outside of the convex strip and fits the trapezoidal block.

[0008] Furthermore, a limiting strip is fixedly connected to the lower end of the baffle, and the limiting strip fits against the lower end of the trapezoidal block.

[0009] Furthermore, the trapezoidal block has an insertion hole on its left side, and an insertion block parallel to the insertion hole is fixedly connected to the right side of the trapezoidal block.

[0010] Furthermore, the upper end of the baffle is higher than the upper surface of the trapezoidal block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the arrangement of trapezoidal blocks, raised strips and baffles, facilitates the welding and fixing of trapezoidal blocks onto water-cooled wall fins.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1 to 2 A water-cooled fireplace wall reinforcement device includes a water-cooled fireplace wall connected by water-cooled wall fins 8. A trapezoidal block 1 is fixedly connected between each pair of adjacent water-cooled wall fins 8. The trapezoidal block 1 is in the shape of an isosceles trapezoid. An arc-shaped groove 2 for avoiding water-cooling pipes is provided on the side of the trapezoidal block 1 facing the water-cooled wall fins 8, so that the trapezoidal block 1 does not contact the water-cooling pipes. A baffle 6 is inserted on the side of the water-cooled wall fins 8 away from the water-cooled fireplace wall.

[0017] Specifically, a convex groove is provided on the side of the trapezoidal block 1 away from the water-cooled fireplace wall, and a convex strip 5 is inserted into the convex groove. The baffle 6 is fixedly connected to the outside of the convex strip 5 and fits the trapezoidal block 1, so as to facilitate the installation of the trapezoidal block 1 in one go.

[0018] Specifically, a limiting strip 7 is fixedly connected to the lower end of the baffle 6. The limiting strip 7 fits against the lower end of the trapezoidal block 1, further ensuring the stability of the connection between the trapezoidal block 1 and the baffle 6.

[0019] Specifically, the trapezoidal block 1 has an insertion hole 4 on its left side, and an insertion block 3 parallel to the insertion hole 4 is fixedly connected to the right side of the trapezoidal block 1. This is used for positioning when installing the trapezoidal block 1 and to ensure that the convex groove between each two adjacent trapezoidal blocks 1 is through.

[0020] Specifically, the upper end of the baffle 6 is higher than the upper surface of the trapezoidal block 1, which facilitates subsequent welding and fixing with the trapezoidal block 1.

[0021] Installation method: The following description is only one of the installation methods in this embodiment. First, the first trapezoidal block 1 is positioned on the water-cooled wall fin 8. After positioning, welding is performed. Then, the insertion hole 4 on the second trapezoidal block 1 is inserted into the corresponding insertion block 3. The convex strip 5 is passed through the convex groove of the first trapezoidal block 1 and then through the convex groove of the second trapezoidal block 1. Then, the second trapezoidal block 1 is welded. After all the trapezoidal blocks 1 are welded, the baffle 6 and the trapezoidal blocks 1 are welded together, that is, the part of the baffle 6 that is higher than the trapezoidal block 1 and the gap between the trapezoidal blocks 1 are welded together to complete the fixation.

[0022] The above are merely preferred embodiments of this utility model and are not intended to limit this utility model. The patent protection scope of this utility model is determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of this utility model should also be included within the protection scope of this utility model.
