Description

Technical Field

[0001] This utility model relates to the technical field of C-type anti-wear tile devices, specifically to a C-type anti-wear tile for the heating surface of a coal-fired boiler. Background Technology

[0002] Currently, most wear-resistant tiles have a semi-circular cross-sectional shape (180 degrees), though some are 120-150 degrees. They are mainly used on finned pipes (water-cooled walls). Wear-resistant tiles are classified into straight wear-resistant tiles, inwardly curved wear-resistant tiles, outwardly curved wear-resistant tiles, side-curved wear-resistant tiles, and S-shaped curved wear-resistant tiles. Straight wear-resistant tiles vary in length from 20mm to 3000mm, with 1000-2000mm being the most common. For curved wear-resistant tiles, processing drawings are generally required, and the drawings must include the following parameters: the outer diameter of the pipe used, the bending radius R of the pipe (to the center of the pipe), the bending angle, and the length of the straight sections on both sides of the curved section of the wear-resistant tile.

[0003] When wear-resistant tiles are long and thick, conventional products may slip, overturn, or fall off during on-site installation. Installation on vertical pipes is time-consuming, labor-intensive, and prone to slippage. Utility Model Content

[0004] Technical problems to be solved

[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides a C-type anti-wear tile for the heating surface of a coal-fired boiler. The outer arc of the anti-wear tile is reinforced with the pipe wall through reinforcing ribs, ensuring no loosening during long-term operation and easy installation. The external reinforcing rib structure, with its smaller outer and larger inner structure, enhances the contact effect between the internal anti-wear tile structure and the pipe, effectively solving the installation problems in existing technologies.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides a C-type anti-wear tile for the heating surface of a coal-fired boiler, including an anti-wear tile, a reinforcing rib fixedly connected to the outer side wall of the anti-wear tile, the inner side of the anti-wear tile maintaining contact with the pipe, one side cross-section of the anti-wear tile being C-shaped, and the inner side walls of both ends of the reinforcing rib being fixed to the outer side wall of one end of the anti-wear tile with an opening.

[0009] Furthermore, the included angle of the outer surface of the wear-resistant tile is α, and ∠α is 144°.

[0010] Furthermore, the reinforcing rib has a tapered structure that is smaller on the outside and larger on the inside.

[0011] Furthermore, both the wear-resistant tiles and the reinforcing ribs are made of titanium alloy steel.

[0012] Furthermore, the wear-resistant tile is formed by pressing on a press or bending on a tube bending machine using a special mold.

[0013] Furthermore, multiple sets of the reinforcing ribs are arranged in an equidistant array on the wear-resistant tile.

[0014] Beneficial effects

[0015] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0016] This utility model strengthens the connection between the outer arc of the wear-resistant tile and the pipe wall through reinforcing ribs, ensuring long-term operation without loosening and easy installation. The external reinforcing rib structure, with its smaller outer and larger inner structure, enhances the contact effect between the internal wear-resistant tile structure and the pipe, increasing the contact area and thus strengthening the connection. Overlapping parts improve structural strength. (This overcomes the problems of ordinary stamped steel plates, which may meet the dimensional requirements in the short term during pressing, but then spring back after use, open in the 180° diameter direction of the wear-resistant tile, and not tightly covering, leading to slippage and overturning). In terms of materials, the material is changed from ordinary stainless steel to titanium alloy steel, further improving the high-temperature wear resistance. During on-site processing, the production time is short, the welding performance is good, the weld is not easy to fall off, the surface is smooth, and the appearance is beautiful and flawless. The curved wear-resistant tile is formed by pressing on a press or bending on a pipe bending machine with a special mold. Attached Figure Description
