Description

Technical Field

[0001] This utility model relates to the field of wear-resistant protective tile technology, and in particular to a wear-resistant protective tile for an air preheater. Background Technology

[0002] The air preheater is a key component of the boiler system, improving boiler efficiency by recovering waste heat from flue gas. However, because the uppermost tubes are in direct contact with high-speed, dust-laden flue gas, they are subjected to long-term airflow erosion and particle wear, resulting in a significantly higher wear rate than tubes in other locations. Frequent replacement of worn tube sections not only increases maintenance costs but also affects the continuous operation of the boiler system. Therefore, the uppermost tubes of existing air preheaters are equipped with wear-resistant tiles. However, these tiles are subject to long-term airflow erosion and particle wear, leading to damage and necessitating replacement. Currently, the wear-resistant tile cylinders are fixed to the uppermost tubes of the air preheater using bolts or welding. This fixing method presents several problems: welding requires cutting the clamps with a cutting machine to remove the wear-resistant tiles, while bolts can rust and become difficult to remove over time. Therefore, both welding and bolt fixing methods affect the efficiency of wear-resistant tile replacement. Summary of the Invention

[0003] This utility model proposes an anti-wear protective tile for an air preheater to solve the problems in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A wear-resistant protective tile for an air preheater includes a tile body, wherein wear-resistant cover plates are provided at both ends of the tile body;

[0006] Multiple clamps are evenly distributed on the bottom surface of the protective tile body. A circular hole is symmetrically opened on each clamp, and a fixing component is installed in the circular hole.

[0007] Preferably, the fixing component includes a circular rod slidably disposed within a circular hole one, a locking block disposed at one end of the circular rod, and a circular plate at the other end. A circular hole three is formed in the circular hole one to cooperate with the circular rod, and the circular rod slides through the circular hole three. A spring is sleeved on the outer wall of the circular rod between the circular plate and the circular hole one. A circular hole two is formed on the protective tile body to cooperate with the circular hole three. Both the circular hole two and the circular hole three are provided with vertical grooves to cooperate with the locking block. An arc-shaped groove is formed at the bottom of the vertical groove to cooperate with the locking block. A locking groove is formed on the bottom surface of the arc-shaped groove to cooperate with the locking block.

[0008] Preferably, a groove is formed on the bottom surface of the circular plate.

[0020] 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.

[0021] Please see Figure 1 - Figure 5 This utility model provides a technical solution:

[0022] A wear-resistant protective tile for an air preheater includes a tile body 1, which is installed on the windward side of the uppermost tube of the air preheater via clamps 2 and fasteners. The tile body 1 is made of S31603 stainless steel, which improves its strength, high temperature resistance, wear resistance, and corrosion resistance, thereby extending its service life. The tile body 1 is 3mm thick and has an arc-shaped design to better fit the air preheater tube, thus protecting it. Wear-resistant cover plates 3 are provided at both ends of the tile body 1, and these cover plates 3 are bolted to both ends to seal the gap between the tile body 1 and the enamel sleeve (existing technology, not shown in the figure).

[0023] Multiple clamps 2 are evenly provided on the bottom surface of the protective tile body 1. Circular holes 4 are symmetrically opened on the clamps 2, and fixing parts are provided in the circular holes 4. The use of fixing parts makes it easy to install the protective tile body 1 on the air preheater tube. Conversely, it also makes it easy to disassemble the protective tile body 1. The operation is simple and convenient, improving the efficiency of replacing the protective tile body 1.

[0024] In this utility model, the fixing component includes a circular rod 10 slidably disposed in a circular hole 4, a locking block 8 disposed at one end of the circular rod 10, and a circular plate 7 at the other end. A circular hole 3 is provided in the circular hole 4 to cooperate with the circular rod 10, and the circular rod 10 slides through the circular hole 3. A spring 5 is sleeved on the outer wall of the circular rod 10 between the circular plate 7 and the circular hole 4. The spring 5 needs to recover its elastic deformation after being compressed, thereby compressing the circular plate 7, further making the locking block 8 stably locked in the locking groove 13, and further improving the stability of the installation of the protective tile body 1. A circular hole 2 9 is provided on the protective tile body 1 to cooperate with the circular hole 3. A vertical groove 11 is provided on both the circular hole 2 9 and the circular hole 3 to cooperate with the locking block 8. An arc groove 12 is provided at the bottom of the vertical groove 11 to cooperate with the locking block 8. A locking groove 13 is provided on the bottom surface of the arc groove 12 to cooperate with the locking block 8.

[0025] In this utility model, a groove 6 is provided on the bottom surface of the circular plate 7. The use of the groove 6 facilitates the rotation of the circular plate 7, thereby facilitating the installation or removal of the protective tile body 1.

[0026] In this utility model, the wear-resistant cover plate 3 is made of S31603 stainless steel, which improves the strength, wear resistance and corrosion resistance of the wear-resistant cover plate 3, thereby increasing the service life of the wear-resistant cover plate 3; and the thickness of the wear-resistant cover plate 3 is 3mm, and the wear-resistant cover plate 3 is in contact with the outer wall of the protective tile body 1.

[0027] Working principle: When using this utility model, when installing the protective tile body 1, first place the protective tile body 1 on the windward side of the uppermost tube of the air preheater, then place the clamp 2 below the air preheater tube and align the circular hole three with the circular hole two 9, then insert the round rod 10 into the circular hole three and move the locking block 8 along the vertical groove 11. When the locking block 8 moves into the arc groove 12, rotate the circular plate 7 to drive the round rod 10 to rotate, thereby moving the locking block 8 above the locking groove 13. Finally, release the circular plate 7, and under the action of the spring 5, the locking block 8 is locked in the locking groove 13. The installation of the protective tile body 1 is achieved by the round rod 10 passing through the circular hole two 9 and the circular hole three.

[0028] When disassembling the protective tile body 1, insert a flat wrench into the flat slot 6 and press the circular plate 7 to move the locking block 8 into the arc slot 12. Then rotate the circular plate 7 to move the locking block 8 into the vertical slot 11. Then release the circular plate 7. Finally, under the action of the spring 5, the round rod 10 is moved out of the circular hole 4, thus realizing the disassembly of the protective tile body 1.
