Technical Field
[0001] This utility model belongs to the field of coal conveying pipe technology, and in particular relates to a reinforcement structure for internal baffles of coal conveying pipe. Background Technology
[0002] The internal arc-shaped baffle of the coal conveying pipe is an arc-shaped structural component installed inside the coal conveying pipeline. It is made of wear-resistant steel or composite materials and its curvature and spacing can be adjusted as needed. In pneumatic conveying, it can guide the gas-coal mixture flow, reduce the impact loss of bends, and prevent blockage. In mechanical conveying, it assists the conveying device to evenly distribute coal, reduce dust and energy consumption. This component optimizes the conveying flow pattern through fluid dynamics design, reduces resistance, and extends the pipeline life. It is an important component to ensure coal conveying efficiency and stable system operation.
[0003] In coal conveying scenarios using coal conveying pipelines, the impact force generated by the coal flow continuously acts on the internal baffles, easily causing baffle deformation, displacement, or even breakage. This not only leads to turbulent coal flow and reduced conveying efficiency but may also cause increased local wear in the pipeline, increasing maintenance costs and safety hazards. Therefore, we need to design a baffle reinforcement structure for the internal baffles of coal conveying pipelines that can effectively resist coal impact, prevent baffle deformation and displacement, maintain a stable coal flow, reduce conveying resistance, significantly improve its impact and deformation resistance, optimize the flow field distribution inside the pipe, reduce conveying resistance and energy consumption, and ensure the stability and continuity of the coal conveying system.

[0010] The beneficial effects of this utility model are:
[0011] 1. This utility model uses the combination of a circular block, a clamping plate, and a connecting piece to fix the circular block and the connecting piece with bolts. The arc-shaped baffle is stably installed in the inner cavity of the coal conveying pipe. Then, when the conveyor belt is conveying coal, the arc-shaped baffle can resist the impact force of the coal, so that the coal can flow smoothly into the bottom of the inner cavity of the coal conveying pipe. This achieves the purpose of resisting the impact force of the coal, preventing the baffle from deforming and shifting, optimizing the flow field inside the pipe, reducing conveying energy consumption, and improving the stability and continuity of system operation.

[0013] 3. By setting a fixing rod, this utility model ensures that the fixing rod guides the two rotating blocks as they rotate on the surface of the fixing rod, thus preventing the two rotating blocks from shifting their positions when they drive the clamping plate to rotate and improving the stability of the rotating blocks.

[0023] In the following description, embodiments of the internal baffle reinforcement structure of the coal conveying pipe of the present invention will be described with reference to the accompanying drawings.
[0024] Figure 1-6This invention illustrates an embodiment of a coal conveying pipe internal baffle reinforcement structure, comprising a coal conveying pipe 1, a conveyor belt 2 installed on the left side of the coal conveying pipe 1, an arc-shaped baffle 3 provided on the right side of the inner cavity of the coal conveying pipe 1, an upper support 4 fixedly connected to the top of the right side of the inner cavity of the coal conveying pipe 1, and a lower hinged support 5 fixedly connected to the right side of the arc-shaped baffle 3. Support rods 6 are bolted to the opposing sides of both the upper support 4 and the lower hinged support 5. Through the cooperation of the upper support 4 and the lower hinged support 5, the two ends of the support rod 6 are respectively connected to the upper support 4 and the lower hinged support 5. Seat 5 forms a rigid support system. During coal impact, the impact force is transmitted and dispersed by the arc-shaped baffle 3, lower hinged support 5, support rod 6, upper support 4, and coal conveying pipe 1, suppressing baffle deformation and displacement, enhancing structural stability, and ensuring the continuous and effective flow guidance function. A fixing plate 7 is fixedly connected to the right side of the arc-shaped baffle 3, and a circular block 8 is fixedly connected to the right side of the fixing plate 7. A connecting plate 9 is fixedly connected to the right side of the inner cavity of the coal conveying pipe 1. Two symmetrical rotating blocks 11 are set on the left side of the connecting plate 9, and a fixing rod 10 is fixedly connected to the central axis on the left side of the connecting plate 9. Block 11 is rotatably connected to the fixing rod 10. The fixing rod 10 guides the two rotating blocks 11 as they rotate on its surface, ensuring that the clamping plate 12 does not shift position when the two rotating blocks 11 rotate, thus improving the stability of the rotating blocks 11. Each of the two rotating blocks 11 has a clamping plate 12 fixedly connected to its end away from the connecting plate 9. The two clamping plates 12 are in contact with the fixing plate 7, and side baffles 13 are fixedly connected to opposite sides of each clamping plate 12. A connecting rod 14 is fixedly connected to the central axis on the right side of the side baffle 13. Connecting pieces 16 are fixedly connected to the top and bottom of the front clamping plate 12. The fixing plate 7 is located between the two connecting pieces 16. Bolts 17 are installed through the surface of the two connecting pieces 16 and the circular block 8. The bolts 17 are fixedly connected to the connecting pieces 16 and the circular block 8 through nuts. A spring 15 is sleeved on the surface of the connecting rod 14. The two ends of the spring 15 are welded to the connecting plate 9 and the side baffle 13 respectively. A circular groove for the bolts 17 to pass through is opened at the central axis of the circular block 8 and the two connecting pieces 16.
[0025] Working Principle: When this utility model is in use, the reinforcement of the arc-shaped baffle 3 during operation of the coal conveying pipe 1 mainly relies on the synergy of multiple layers. First, the lower hinged support 5 is fixedly connected to the bottom of the arc-shaped baffle 3, while the upper support 4 is firmly connected to the inner wall of the top of the coal conveying pipe 1. The two are rigidly connected by the support rod 6, forming a stable triangular support structure. When coal impacts the arc-shaped baffle 3, the impact force is transmitted along the path of the arc-shaped baffle 3, the lower hinged support 5, the support rod 6, the upper support 4, and the coal conveying pipe 1. While dispersing the impact force, it effectively suppresses the overall deformation and displacement of the arc-shaped baffle 3. Second, the fixing plate 7 is welded to the back of the arc-shaped baffle 3, and a circular block 8 is fixed on its right side. The clamping plates 12 are connected to both sides by rotating blocks 11. When coal impacts the arc-shaped baffle 3, the impact... The force pushes the fixed plate 7 to squeeze the clamping plate 12, causing the clamping plate 12 to rotate around the fixed rod 10. Through the connecting piece 16 and the bolt 17, the force is transmitted to the connecting plate 9 and further dispersed to the inner wall of the coal conveying pipe 1, absorbing the impact energy and preventing the components from being damaged due to stress concentration. The side baffle 13 limits the swing amplitude of the clamping plate 12 to prevent it from deviating excessively, ensuring that the arc-shaped baffle 3 always maintains a reasonable guiding angle, optimizing the coal flow path, and reducing resistance and secondary impact. In the actual conveying process, the conveyor belt 2 sends coal into the coal conveying pipe 1. The coal impacts the arc-shaped baffle 3. After the above-mentioned reinforcement structure disperses and absorbs the impact force, the arc-shaped baffle 3 maintains a stable guiding state, guiding the coal to flow along a reasonable path, and finally smoothly conveying it to the bottom of the inner cavity of the coal conveying pipe 1, achieving stable coal conveying.
[0026] In summary, the internal baffle reinforcement structure of this coal conveying pipe, through the combined use of the circular block 8, the clamping plate 12, and the connecting piece 16, allows the bolt 17 to fix the circular block 8 and the connecting piece 16. The arc-shaped baffle 3 is stably installed in the inner cavity of the coal conveying pipe 1. Then, when the conveyor belt 2 is conveying coal, the arc-shaped baffle 3 can resist the impact force of the coal, thereby allowing the coal to flow smoothly into the bottom of the inner cavity of the coal conveying pipe 1. This achieves the purpose of resisting the impact force of the coal, preventing the baffle from deforming and shifting, optimizing the flow field inside the pipe, reducing conveying energy consumption, and improving the stability and continuity of system operation.
