Description

Technical Field

[0001] This utility model relates to the field of boiler equipment technology, and in particular to a lightweight grate support. Background Technology

[0002] A grate is a component in a boiler or industrial furnace that holds and effectively combusts solid fuel, with the grate support being cast as a single piece.

[0003] The weight of a single-piece grate support increases the overall load on the boiler or industrial furnace, leading to faster equipment wear and a shorter service life. Furthermore, the thickness of a single-piece cast grate affects the even distribution of heat, thus impacting fuel combustion efficiency and reducing thermal energy utilization. The heavy grate also makes maintenance and replacement more difficult, increasing maintenance costs and downtime.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a lightweight grate support to reduce the weight of the grate support.

[0006] The technical solution of this utility model is as follows:

[0007] A lightweight grate support is mounted on the furnace frame to support the grate bars. The lightweight grate support includes a support plate, a connecting rod, and a limiting rod.

[0008] The support plate consists of two pieces;

[0009] The connecting rod is disposed between the two support plates;

[0010] The limiting rod is disposed between the two support plates;

[0011] The two support plates are provided with a connecting hole and a limiting hole respectively; the connecting hole is a through hole, and the connecting rod is disposed between the two support plates through the connecting hole; the limiting hole is a blind hole, and the limiting rod is disposed between the two support plates through the limiting hole, with the end face of the limiting rod contacting the bottom of the limiting hole.

[0012] A further technical solution is that the limiting rod is provided with two rods.

[0013] A further technical solution is that, along the length of the support plate, the limiting rod is disposed on both sides of the connecting rod.

[0014] A further technical solution is that the height of one of the limiting rods is higher than the height of the connecting rod.

[0015] A further technical solution is that the connecting rod and the limiting rod are hollow rods.

[0016] A further technical solution is that the support plate includes an upper plate, a lower plate, and a support rod; the support rod is disposed between the upper plate and the lower plate, and the support rod connects the upper plate and the lower plate.

[0017] A further technical solution is that a circular cover is provided between the support plates; a limiting hole is formed around the inner wall of the circular cover; and the support rod is connected to the circular cover.

[0018] A further technical solution is that a ring is provided between the support plates; the inner wall of the ring surrounds the connecting hole.

[0019] A further technical solution is that the lower plate is bent inward toward the upper plate; a groove is formed on the surface of the lower plate away from the upper plate.

[0020] A further technical solution is that the two ends of the lower plate are connected to the two ends of the upper plate.

[0021] The beneficial technical effects of this utility model are as follows:

[0022] (1) The lightweight grate support in this utility model is a split design, which connects two support plates through connecting rods and limiting rods. The split design allows for reduced material usage in the grate plates, optimizing the strength-to-weight ratio of the structure and reducing the weight of the grate plates. The lightweight grate plates reduce the overall load on the boiler or industrial furnace, extending the service life of the equipment. The reduced weight also facilitates disassembly and maintenance by personnel, reducing downtime during equipment maintenance. The lightweight grate plates are also smaller in size, facilitating uniform heat conduction and improving fuel combustion efficiency. In addition, by using the limiting rod to abut against the bottom of the limiting hole, the distance between the two support plates can be quickly determined, improving the assembly efficiency of the grate support.

[0023] (2) Furthermore, two limiting rods are provided, which can more stably support the grate plates. A connecting rod is positioned between the two limiting rods, and when the distance between the two support plates is determined by the limiting rods, the limiting rods abut against both ends of the support plate's length. When the two support plates are positioned by the limiting rods, the limiting rods provide more stable support for the two support plates.

[0024] (3) Furthermore, the height of one of the limiting rods is higher than the height of the connecting rod, creating a height difference between the connecting rod and the limiting rod. When the grate plates are supported by the connecting rod and the limiting rod, the grate plates are more likely to form an inclination angle, facilitating the transport of the stacked solid fuel along the inclined grate.

[0032] Example 1

[0033] Figure 1 The diagram shows a front view of the lightweight grate support in Embodiment 1 of this utility model. Figure 2 This diagram illustrates the assembly structure of the connecting rod, limiting rod, and support plate in the lightweight grate support according to Embodiment 1 of this invention. Please refer to... Figure 1and Figure 2 A lightweight grate support is installed on the furnace frame to support the grate bars. The lightweight grate support includes a support plate 1, a connecting rod 2, and a limiting rod 3. Two support plates 1 are provided. The connecting rod 2 is positioned between the two support plates 1. The limiting rod 3 is positioned between the two support plates 1. The two support plates 1 are connected by the connecting rod 2 and the limiting rod 3. This split design allows for reduced material usage for the grate bars, optimizing the strength-to-weight ratio of the structure and reducing the weight of the grate bars. The lightweight grate bars reduce the overall load on the boiler or industrial furnace, extending the service life of the equipment. The reduced weight also facilitates disassembly and maintenance by personnel, reducing downtime during equipment maintenance. The smaller size of the lightweight grate bars also facilitates more uniform heat transfer, improving fuel combustion efficiency.

[0034] The two support plates 1 are respectively provided with connecting holes 141 and limiting holes 131. The connecting holes 141 are through holes, through which the connecting rod 2 is positioned between the two support plates 1. The limiting holes 131 are blind holes, through which the limiting rod 3 is positioned between the two support plates 1, with the end face of the limiting rod 3 contacting the bottom of the limiting hole 131. By having the limiting rod 3 abut against the bottom of the limiting hole 131, the distance between the two support plates 1 can be quickly determined, improving the assembly efficiency of the grate support.

[0035] Please refer to Figure 1 Two limiting rods 3 are provided to provide more stable support for the grate plates. Preferably, the limiting rods 3 are located on both sides of the connecting rod 2 along the length of the support plate 1. When the distance between the two support plates 1 is determined by the limiting rods 3, the limiting rods 3 abut against both ends of the length of the support plate 1. When the two support plates 1 are positioned by the limiting rods 3, the limiting rods 3 provide more stable support for the two support plates 1.

[0036] Please refer to Figure 1 One of the limiting rods 3 is higher than the connecting rod 2, creating a height difference between the connecting rod 2 and the limiting rod 3. When the grate bars are supported by the connecting rod 2 and the limiting rod 3, the grate bars are more likely to form an inclination angle, facilitating the transport of the stacked solid fuel along the inclined grate.

[0037] Preferably, the connecting rod 2 and the limiting rod 3 are hollow rods. This reduces the weight of the connecting rod 2 and the limiting rod 3, further reducing the overall weight of the lightweight grate.

[0038] The specific assembly process in this embodiment is as follows:

[0039] The assembly personnel first move the support plate 1 onto the furnace frame. Then, they insert the connecting rod 2 into the two connecting holes 141. They then insert the limiting rod 3 into the two limiting holes 131. The distance between the two support plates 1 is adjusted until both ends of the limiting rod 3 abut against the bottom of the two limiting holes 131, thus completing the assembly of the lightweight grate.

[0040] Example 2

[0041] Figure 3 The diagram shows a front view of the support plate in the lightweight grate support according to Embodiment 2 of this utility model. Please refer to... Figure 1 and Figure 2 Based on Embodiment 1, Embodiment 2 discloses a lightweight grate support plate 1, which includes an upper plate 11, a lower plate 15, and a support rod 12. The support rod 12 is disposed between the upper plate 11 and the lower plate 15, and connects the upper plate 11 and the lower plate 15. The upper plate 11 and the lower plate 15 are connected by the support rod 12, reducing the weight of the entire support plate 1.

[0042] The lower plate 15 connects to the upper plate 11 at both ends of its length, forming a closed loop to enhance the connection strength between the lower plate 15 and the upper plate 11. A circular cover 13 is also provided between the support plates 1. A limiting hole 131 is formed around the inner wall of the circular cover 13. A ring 14 is provided between the support plates 1 and the support rod 12, connecting to the circular cover 13. A connecting hole 141 is formed around the inner wall of the ring 14. The lower plate 15 is recessed and bent towards the upper plate 11. A groove 151 is formed on the surface of the lower plate 15 away from the upper plate 11.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
