Description

Technical Field

[0001] This utility model relates to a descaling manifold, and more particularly to a high-pressure descaling manifold for H-beams, belonging to the field of steel section rolling technology. Background Technology

[0002] During the rolling process of H-beams, iron oxide scale forms on the surface of the billet. If this scale is not removed in time, it will affect the surface quality of the H-beams and subsequent processing. Currently, high-pressure water descaling is commonly used to remove the iron oxide scale, but existing high-pressure descaling manifolds for H-beams have several problems. For example, the uniformity of water spraying from the descaling manifold is poor, resulting in ineffective descaling in some areas of the H-beam surface; the structural design of the manifold is not conducive to the efficient delivery and spraying of high-pressure water, resulting in significant energy loss; furthermore, the installation and maintenance of the manifold are not convenient, increasing production costs and downtime. Therefore, it is necessary to develop a high-pressure descaling manifold for H-beams to improve descaling efficiency and production efficiency. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide an H-beam high-pressure descaling manifold to solve the defects of uneven descaling effect, incomplete oxide scale removal, high energy loss, and inconvenient installation and maintenance, thereby achieving efficient and uniform descaling effect and reducing production costs.

[0004] Therefore, the technical solution adopted by this utility model is: A high-pressure descaling manifold for H-beams includes a main body with a square structure. Side nozzle seats are provided on both the left and right inner sides of the main body. First nozzles corresponding to the side surfaces of the H-beams are arranged from top to bottom at the front end of the side nozzle seats. Upper convex nozzle seats and lower convex nozzle seats are provided on the upper inner side and lower inner side of the main body, respectively. Upper second nozzles corresponding to the upper concave cavity and upper end face of the H-beams are installed in a stepped manner on the front side of the upper convex nozzle seats. Lower second nozzles corresponding to the lower concave cavity and lower end face of the H-beams are installed in a stepped manner on the front side of the lower convex nozzle seats.

[0005] As a further improvement to the above technical solution, the main body consists of a tee pipe, three 90-degree elbows and four branch pipes.

[0006] As a further improvement to the above technical solution, the first nozzle is a high-pressure fan-shaped nozzle, the center line of the high-pressure fan-shaped nozzle is offset by 15 degrees relative to the plane formed by the main body, and the front end face of the first nozzle is 60mm away from the side of the H-beam.

[0007] As a further improvement to the above technical solution, both the upper convex nozzle seat and the lower convex nozzle seat are two-step convex nozzle seats, and the upper second nozzle and the lower second nozzle are both installed on the front end of the two-step convex nozzle seat and the end face of the two steps.

[0008] As a further improvement to the above technical solution, both the upper second nozzle and the lower second nozzle are high-pressure fan-shaped nozzles. The center line of the upper second nozzle is offset by 20 degrees relative to the plane formed by the main body, and the center line of the lower second nozzle is offset by 10 degrees relative to the plane formed by the main body. The distance between the front end face of the upper second nozzle and the lower second nozzle and the bottom surface of the H-shaped steel cavity is 60mm.

[0009] The advantages of this utility model are: 1. This utility model, by installing a side nozzle seat, an upper convex nozzle seat, and a lower convex nozzle seat on the inner side of the main body, can guide high pressure to approach each surface of the H-beam at equal distances. In conjunction with the high pressure fan-shaped nozzle, it ensures that the high pressure water impacts each part with equal force, so that the high pressure water can be evenly sprayed onto the surface of the H-beam, thereby improving the descaling effect.

[0010] 2. The main body consists of a tee pipe, three 90-degree elbows and four branch pipes connected in series to form a square structure, which makes installation, disassembly and maintenance convenient and quick, reduces downtime and improves production efficiency. Attached Figure Description

Detailed Implementation

[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] A high-pressure descaling manifold for H-beams includes a main body with a square structure. Side nozzle seats 1 are provided on both the left and right inner sides of the main body. First nozzles 3, corresponding to the side surfaces of the H-beams 2, are arranged from top to bottom at the front end of each side nozzle seat 1. An upper convex nozzle seat 4 and a lower convex nozzle seat 5 are respectively provided on the upper and lower inner sides of the main body. An upper second nozzle 6, corresponding to the upper concave cavity and upper end face of the H-beams 2, is installed in a stepped manner on the front side of the upper convex nozzle seat 4. A lower second nozzle 7, corresponding to the lower concave cavity and lower end face of the H-beams 2, is installed in a stepped manner on the front side of the lower convex nozzle seat 5. The side nozzle seats 1, upper convex nozzle seats 4, and lower convex nozzle seats 5 are equidistant from each other, closely approximating the shape of the H-beams 2, and simultaneously guiding high-pressure water to flow evenly to each nozzle. This achieves uniform impact on the H-beams under the same pressure, thereby reducing energy loss.

[0017] As a further improvement to the above technical solution, the main body is composed of a three-way pipe 8, three 90-degree elbows 9 and four branch pipes 10 connected in series to form a square structure. The bevel position of the three-way pipe 8 is the water inlet, which is used to connect to the high-pressure water source main body. The inner cavities of the side nozzle seat, the upper convex nozzle seat and the lower convex nozzle seat are all connected to the branch pipes.

[0018] As a further improvement to the above technical solution, the first nozzle 3 is a high-pressure fan-shaped nozzle with a fan-shaped spray angle of 27 degrees. The center line of the high-pressure fan-shaped nozzle is offset by 15 degrees relative to the plane formed by the main pipe. This is to avoid mutual interference of high-pressure water during spraying, which would reduce the impact effect, and to achieve full coverage of the entire surface area of ​​the H-beam 2 on all four sides at equal distances. The front end of the first nozzle 3 is 60mm away from the side of the H-beam to avoid rebound water generated when the high-pressure water hits the H-beam. A filter screen is installed inside the first nozzle to filter impurities in the water and prevent clogging of the nozzle.

[0019] As a further improvement to the above technical solution, the upper convex nozzle seat 4 and the lower convex nozzle seat 5 are both two-step convex nozzle seats, and the upper second nozzle 6 and the lower second nozzle 7 are both installed on the front end of the two-step convex nozzle seat and the end face of the two steps.

[0020] As a further improvement to the above technical solution, both the upper second nozzle 6 and the lower second nozzle 7 are high-pressure fan-shaped nozzles. The center line of the upper second nozzle 6 is offset by 20 degrees relative to the plane formed by the main body, and the center line of the lower second nozzle 7 is offset by 10 degrees relative to the plane formed by the main body. The distance between the front end face of the upper second nozzle 6 and the lower second nozzle 7 and the bottom surface of the H-beam cavity is 60mm, so as to avoid the rebound water generated when the high-pressure water hits the H-beam.

[0021] The branch pipes of the main pipe are made of high-strength, corrosion-resistant alloy steel to ensure the service life of the manifold under high-pressure water conditions. The nozzles are made of wear-resistant and high-pressure-resistant ceramic materials to improve the nozzles' wear resistance and spraying effect.

[0022] This invention, by installing a side nozzle seat, an upper convex nozzle seat, and a lower convex nozzle seat on the inner side of the main body, can guide high pressure to approach each surface of the H-beam at equal distances. In conjunction with the high-pressure fan-shaped nozzle, it ensures that the high-pressure water impacts each part with equal force, so that the high-pressure water can be evenly sprayed onto the surface of the H-beam, thereby improving the descaling effect.

[0023] The main body consists of a tee pipe, three 90-degree elbows, and four branch pipes connected in series to form a square structure. This allows for convenient and quick installation, disassembly, and maintenance, reducing downtime and improving production efficiency. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
