Abstract

The present disclosure relates to a pipeline anti-wear device and a boiler pipeline system. The pipeline anti-wear device comprises: an anti-wear tile assembly comprising at least two interconnected anti-wear tiles for surrounding the outside of the pipeline; and a sliding structure disposed between two adjacent anti-wear tiles to enable relative sliding between the tiles when the tiles expand due to heat. This effectively solves the problem of existing pipeline anti-wear tiles being unable to freely expand and contract due to thermal expansion, resulting in deformation, displacement, and even detachment of the tiles.

Description

Technical Field

[0001] The present disclosure relates to the technical field of pipeline anti-wear, and in particular to a pipeline anti-wear device and a boiler pipeline system. Background Art

[0002] Anti-wear tiles are special accessories for boilers. Anti-wear tiles are also called anti-wear covers, anti-wear plates, anti-wear protective tiles, anti-wear covers, etc. They are commonly used accessories for the heating surface pipes of power station boilers. Anti-wear tiles are mainly used on the windward side of the heating surface pipes such as the boiler's superheater, reheater, economizer, and water-cooled wall pipes. Their main function is to protect the windward side of the boiler pipes and reduce the wear of smoke and dust on the tube rows. They are generally used in conjunction with clamps to use the clamps to fix the anti-wear tiles on the pipes, thereby preventing the pipes from wearing.

[0003] However, this type of anti-wear tile presents certain problems during use. For example, due to the different materials of the anti-wear tile and the heating surface tubes, the expansion coefficients of the anti-wear tile and the heating surface tubes are different. This can cause the anti-wear tile to deform, shift, and fall off after thermal expansion. Furthermore, the vibrations of the furnace during operation and the loose installation of the anti-wear tile make it very easy for the anti-wear tile to deflect, deform, and fall off after thermal expansion, ultimately resulting in the loss of protection for the boiler heating surface tubes. The anti-wear tile cannot freely expand and contract during thermal expansion, and there is no limit device to prevent the anti-wear tile from flipping over when thermal expansion occurs.

[0004] Therefore, there is an urgent need for an anti-wear device that can prevent pipes from wearing and is not prone to displacement, falling off or flipping after the anti-wear tiles expand due to heat. Summary of the Invention

[0005] The purpose of the present disclosure is to provide a pipeline anti-wear device and a boiler pipeline system, which can solve the problem that the existing pipeline anti-wear tiles cannot freely expand and contract after thermal expansion, resulting in deformation, displacement and falling off of the anti-wear tiles.

[0006] In order to achieve the above objectives, the first aspect of the present disclosure provides a pipeline anti-wear device, comprising:

[0007] The anti-wear tile assembly includes at least two anti-wear tiles spliced ​​together to surround the outside of the pipeline;

[0008] The sliding structure is arranged between two adjacent anti-wear tiles so as to enable the two adjacent anti-wear tiles to slide relative to each other when the anti-wear tiles expand due to heat.

[0009] Optionally, the sliding structure includes a sliding rod and a sliding groove;

[0010] The sliding rod is fixed to one end of one of the anti-wear tiles, and the sliding groove is provided at one end of an adjacent anti-wear tile;

[0011] When two adjacent anti-wear tiles are spliced ​​together, the sliding rod on one of the anti-wear tiles is slidably arranged in the sliding groove of the other anti-wear tile.

[0012] Optionally, two sliding rods are provided on the anti-wear tile, and a gap is provided between the two sliding rods;

[0013] When two adjacent anti-wear tiles are spliced ​​together, the two sliding rods on one of the anti-wear tiles are slidably arranged in the sliding groove of the other anti-wear tile.

[0014] Optionally, the diameter of the sliding rod is smaller than the width of the sliding groove.

[0015] Optionally, the width of the sliding groove on the anti-wear tile is 0.8-1.2 cm, and the diameter of the sliding rod is 0.6-1 cm.

[0016] Optionally, the pipeline anti-wear device further includes an anti-overturning structure;

[0017] The anti-overturning structure is arranged between two adjacent anti-wear tiles to prevent the anti-wear tiles from overturning.

[0018] Optionally, the pipeline anti-wear device also includes an anti-flip structure between two adjacent anti-wear tiles, and the anti-flip structure includes a limit rod, which is arranged on the sliding rod to prevent the end of one of the anti-wear tiles having the sliding groove from falling off the sliding rod of the adjacent anti-wear tile.

[0019] Optionally, there is a gap between the limiting rod and the anti-wear tile.

[0020] A second aspect of the present disclosure provides a boiler piping system, comprising:

[0021] pipeline;

[0022] A pipeline anti-wear device is provided on the pipeline, and the pipeline anti-wear device is the pipeline anti-wear device described in any one of the above embodiments.

[0023] Optionally, the boiler piping system further comprises a clamping ring;

[0024] The clamping ring is arranged on the anti-wear tiles at both ends of the anti-wear tile group, and both ends of the clamping ring are fixed to the pipeline.

[0025] Through the above technical solution, an anti-wear tile group is set up, and a sliding structure is set between two adjacent anti-wear tiles of the anti-wear tile group. When the anti-wear tile group is set at the pipeline for anti-wear, if the anti-wear tile expands due to heat, the two adjacent anti-wear tiles can slide relative to each other, thereby avoiding the problem that the anti-wear tiles cannot move and are deformed, which ultimately leads to damage or falling off of the anti-wear tiles.

[0035] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0036] The present disclosure provides a pipe anti-wear device, which can be installed on pipes of a boiler pipe system, such as superheater, reheater, economizer or water-cooled wall pipes, to prevent the pipes from wearing.

[0037] like Figure 1As shown, the pipeline anti-wear device includes an anti-wear tile assembly and a sliding structure 20. The anti-wear tile assembly includes at least two mutually connected anti-wear tiles 10. The mutually connected anti-wear tiles 10 are used to surround the outside of the pipeline 50 to protect the pipeline 50 from wear. The sliding structure 20 is disposed between two adjacent anti-wear tiles 10. That is, the two adjacent anti-wear tiles 10 are connected by the sliding structure 20 so that the two adjacent anti-wear tiles 10 can slide relative to each other when the anti-wear tiles 10 expand due to heat.

[0038] Through the setting of this structure, after the anti-wear tiles 10 that are spliced ​​together are set on the pipe 50 and the two adjacent anti-wear tiles 10 are connected to each other by using the sliding structure 20, when the boiler is running, the anti-wear tiles 10 expand due to heat or the boiler vibrates and causes the anti-wear tiles 10 to move, the two adjacent anti-wear tiles 10 can slide relative to each other, so that the anti-wear tiles 10 have a certain sliding space, avoiding the problem that the anti-wear tiles 10 cannot move relative to each other, causing the anti-wear tiles 10 to deflect or deform, and ultimately causing the anti-wear tiles 10 to fall off.

[0039] In some embodiments, combined Figure 3 、 Figure 4 and Figure 5 As shown, the above-mentioned sliding structure 20 includes a sliding rod 21 and a sliding groove 22, wherein the sliding rod 21 is fixedly connected to one end of one of the anti-wear tiles 10, and the sliding groove 22 is arranged at one end of the adjacent anti-wear tile 10. When the two adjacent anti-wear tiles 10 are spliced ​​together, the sliding rod 21 on one of the anti-wear tiles 10 is slidably arranged in the sliding groove 22 of the other anti-wear tile 10, that is, the sliding rod 21 is inserted into the sliding groove 22 of the adjacent anti-wear tile 10.

[0040] In this way, when the anti-wear tiles 10 are displaced due to thermal expansion, the sliding rod 21 can move in the sliding groove 22 so that two adjacent anti-wear tiles 10 slide relative to each other.

[0041] In a further embodiment, Figure 2 As described above, there are two sliding rods 21 on the above-mentioned anti-wear tile 10, and there is a gap between the two sliding rods 21. When two adjacent anti-wear tiles 10 are spliced ​​together, the two sliding rods 21 on one anti-wear tile 10 are slidably set in the sliding groove 22 of the other anti-wear tile 10.

[0042] By setting up two sliding rods 21, the connection between two adjacent anti-wear tiles 10 can be made more stable without affecting the relative sliding of the two adjacent anti-wear tiles 10. In addition, if one of the sliding rods 21 breaks or has other damage problems, the other sliding rod 21 can be used for supporting the connection to avoid the anti-wear tiles 10 falling off directly.

[0043] Furthermore, the sliding rod 21 is cylindrical, and the diameter of the sliding rod 21 is smaller than the width of the sliding slot 22 .

[0044] Through such a setting, the sliding rod 21 can also have a certain movement gap in the width direction of the sliding groove 22, so that when the anti-wear tile 10 is heated and offset, the anti-wear tile 10 has a certain movement space in all directions, so as to further avoid the anti-wear tile 10 from being deformed due to the limitation of the movement space.

[0045] Among them, the width of the sliding groove 22 on the above-mentioned anti-wear tile 10 is 0.8-1.2 cm, and the diameter of the sliding rod 21 is 0.6-1 cm. For example, the width of the sliding groove 22 is 1 cm, and the diameter of the sliding rod 21 is 0.8 cm. In this way, after the sliding rod 21 is inserted into the sliding groove 22, the sliding rod 21 can have a certain movable gap in the width direction of the sliding groove 22.

[0046] In some embodiments, as Figure 1 As shown, the pipeline anti-wear device further includes an anti-overturning structure, which is provided between two adjacent anti-wear tiles 10 to prevent the anti-wear tiles 10 from overturning.

[0047] The anti-flip structure is used to prevent the anti-wear tile 10 from flipping and falling due to thermal expansion and displacement after being installed on the pipe 50.

[0048] In this embodiment, if Figure 1 and Figure 2 As shown, the anti-flip structure includes a limit rod 30, which is connected to the sliding rod 21, and the limit rod 30 and the sliding rod 21 are perpendicular to each other to prevent one end of one of the anti-wear tiles 10 having the sliding groove 22 from falling off the sliding rod 21 of the adjacent anti-wear tile 10.

[0049] When the anti-wear tile 10 expands due to heat and flips over, the anti-wear tile 10 will abut against the limiting rod 30, so that the limiting rod 30 will prevent the anti-wear tile 10 from continuing to flip over, thereby preventing the anti-wear tile 10 from falling off due to flipping.

[0050] Furthermore, there is a gap between the above-mentioned limit rod 30 and the anti-wear tile 10, that is, after the two adjacent anti-wear tiles 10 are connected to each other, the sliding rod 21 on one of the anti-wear tiles 10 is connected to the sliding groove 22 of the adjacent anti-wear tile 10, and the limit rod 30 is connected to the sliding rod 21, there is a gap between the sliding rod 21 and the above-mentioned anti-wear tile 10 provided with the sliding groove 22.

[0051] In this way, when the anti-wear tile 10 is displaced due to thermal expansion, there is a certain amount of room for the anti-wear tile 10 to flip over, thereby further preventing the anti-wear tile 10 from being deformed.

[0052] It should be noted that the above-mentioned limit rod 30 can be directly fixedly connected to the sliding rod 21, such as directly welding the limit rod 30 to the sliding rod 21; the limit rod 30 can also be detachably connected to the sliding rod 21 for subsequent disassembly, such as providing an external thread on the limit rod 30 and providing a threaded hole on the limit rod 30 so that the limit rod 30 is threadedly connected to the sliding rod 21, so that the limit rod 30 can be conveniently installed and disassembled.

[0053] Based on the same technical concept, an embodiment of the present disclosure further provides a boiler piping system, which includes a pipe 50 and the pipe anti-wear device involved in the above embodiment, wherein the pipe anti-wear device is arranged on the pipe 50.

[0054] By setting the pipeline anti-wear device on the pipeline 50 of the boiler pipeline system, it can play a good anti-wear role on the pipeline 50 of the boiler pipeline system. At the same time, after the pipeline anti-wear device is heated and expanded, the anti-wear tiles 10 of the pipeline anti-wear device will not be deformed or fall off.

[0055] In some embodiments, as Figure 1 As shown, the boiler piping system further includes a clamping ring 40 , which is connected to the anti-wear tiles 10 at both ends of the anti-wear tile group, and both ends of the clamping ring 40 can be fixed to the pipe 50 .

[0056] By setting the clamping ring 40 , when the anti-wear tile group is set on the pipe 50 , the anti-wear tiles 10 at both ends of the anti-wear tile group can be fixed to the pipe 50 using the clamping ring 40 , so that the anti-wear tile group is stably fixed to the pipe 50 .

[0057] When using the clamping ring 40 to fix the anti-wear tile 10 to the pipe 50, the anti-wear tile 10 can be first set on the pipe 50, and then the clamping ring 40 can be set on the anti-wear tile 10, and the two ends of the clamping ring 40 can be fitted to the pipe 50. Then, the clamping ring 40 is welded to the position where the pipe 50 is fitted, and the two ends of the clamping ring 40 are welded and fixed to the pipe 50. In this way, the anti-wear tiles 10 at both ends of the anti-wear tile group can be stably fixed to the pipe 50 using the clamping ring 40.

[0058] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

[0059] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0060] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
