Description

Technical Field

[0001] This utility model belongs to the technical field of chain grate plates, specifically relating to a chain grate plate strength enhancement structure. Background Technology

[0002] The chain grate machine is a non-standard, customized large-scale metallurgical sintering equipment, mainly used for drying and preheating materials. It has been used in the cement and metallurgical industries in China for many years.

[0003] Chain grate plates are an important component of chain grate machines, mainly used in the drying, preheating, and conveying stages of pellet production. Currently available chain grate plates have a simple structure. While they can perform drying and preheating functions, their overall strength is insufficient. Furthermore, during drying and preheating, the drying temperature needs to be maintained at 800-900℃, and the preheating temperature can reach 1050-1100℃. With accumulated working time, the chain grate plates may become damaged, requiring replacement, which is extremely inconvenient. Utility Model Content

[0004] The purpose of this utility model is to address the above-mentioned shortcomings in the prior art by providing a strength-enhancing structure for chain grate plates, thereby solving the problems of the existing chain grate plate structure being too simple and lacking in strength.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A chain grate plate strength enhancement structure includes a plate body; the plate body includes a base layer, a first reinforcement layer, an elastic layer and a second reinforcement layer that are closely distributed from bottom to top; The top surface of the second reinforcement layer is provided with a ceramic coating; multiple sets of reinforcing ribs are evenly installed on the second reinforcement layer, the elastic layer, the first reinforcement layer, and the base layer.

[0006] Furthermore, the reinforcing rib passes sequentially through the first reinforcing layer and the elastic layer along the base layer, and is housed within the second reinforcing layer.

[0007] Furthermore, the reinforcing rib includes multiple vertical ribs, each of which is fitted with multiple fixing sleeves, and a horizontal rib connects the two fixing sleeves on two adjacent vertical ribs.

[0008] Furthermore, the plurality of vertical ribs are arranged in a vertical direction and form a columnar structure; Furthermore, the first and second reinforcing layers have the same structure, both including multiple vertical ribs and multiple horizontal ribs, which are arranged in an alternating pattern.

[0009] Furthermore, the elastic layer includes one or more elastic sublayers, each with the same structure, including multiple elastic units, which are mutually compressed and arranged neatly.

[0010] Furthermore, the elastic unit includes an elastic ball one, an elastic column and an elastic ball two; the elastic ball one is connected to multiple elastic columns, and each elastic column is connected to an elastic ball two.

[0011] Furthermore, the base layer is made of metal.

[0012] The chain grate plate strength enhancement structure provided by this utility model has the following beneficial effects: This invention incorporates a ceramic coating, reinforcing ribs, an elastic layer, a first reinforcing layer, and a second reinforcing layer. The alternating arrangement of the first and second reinforcing layers significantly enhances the overall tensile strength of the board. Combined with the reinforcing ribs, this improves the overall rigidity of the board. The elastic layer cushions the board under stress, preventing strong external forces from directly impacting the surface and extending its lifespan. The ceramic coating ensures excellent high-temperature resistance, reducing the impact of high temperatures on the board during operation and effectively improving its overall strength.

[0033] 5. Material selection and heat treatment: The base layer 11 and the reinforcing layers (12 and 14) must be made of high-strength, high-temperature resistant metal materials (such as heat-resistant steel). Heat treatment (such as quenching and tempering) is required to improve the mechanical properties and heat resistance of the materials.

[0034] 6. Dimensional accuracy and surface flatness: Plate 1 needs to ensure high dimensional accuracy and surface flatness to ensure the stability of installation and operation on the chain grate machine.
