DETAILED DESCRIPTION

[0014] The present invention will be further described below with reference to the accompanying drawings and through examples.

[0015] A device for reducing vibration of fixed pipelines is arranged between the main pipeline 8 of the clean ring high-pressure pump group and the high-pressure filter outlet pipeline 10; it includes a pipeline reinforcement plate 1, a pipeline reinforcement plate 2, a pipeline reinforcement plate 3, a support column 4 and a support column 2 5. The pipeline reinforcement plate 1 and the pipeline reinforcement plate 2 are arranged on the lower surface of the main pipeline 8 of the clean ring high-pressure pump group, and the pipeline reinforcement plate 3 is arranged on the upper surface of the high-pressure filter outlet pipeline 10; the two ends of the support column 1 4 are respectively vertically connected to the pipeline reinforcement plate 2 2 and the pipeline reinforcement plate 3 3, the support column 2 5 is arranged at an angle, and the two ends of the support column 2 5 are respectively connected to the pipeline reinforcement plate 1 and the pipeline reinforcement plate 3 3 to form a triangular frame structure.

[0016] A plurality of pipe supports 12 are provided on the main pipeline 8 of the clean-ring high-pressure pump group and the outlet pipeline 10 of the high-pressure filter to play a supporting role.

[0017] The pipeline reinforcement plate 1 is arranged at the connection between the clean ring high-pressure pump group main pipeline 8 and the clean ring high-pressure pump group outlet pipeline 9, the pipeline reinforcement plate 3 is arranged at the pipe support position of the high-pressure filter outlet pipeline 10, and the pipeline reinforcement plate 2 2 is arranged on the clean ring high-pressure pump group main pipeline 8 between the two clean ring high-pressure pump group outlet pipelines 9, and corresponds to the pipeline reinforcement plate 3 3.

[0018] The pipeline reinforcement plate 1 and pipeline reinforcement plate 2 are both square reinforcement plates, and their length is twice the outer diameter of the support column 1 4; the pipeline reinforcement plate 3 is a rectangular reinforcement plate, and its length is three times the outer diameter of the support column 1 4, and its width is the same as the length of the square reinforcement plate.

[0019] The outer diameters of the support column 1 4 and the support column 2 5 are the same.

[0020] In this embodiment, there are three clean-ring high-pressure pump groups 7, one clean-ring high-pressure diesel engine pump 11, and two high-pressure filters 6; the vibration amplitude of the clean-ring high-pressure pump group outlet pipe 9 located in the middle position is relatively high, and a pipe reinforcement plate 1 is provided on the lower surface of the clean-ring high-pressure pump group main pipe 8 at the connection position between the clean-ring high-pressure pump group main pipe 8 and the clean-ring high-pressure pump group outlet pipe 9, and a pipe reinforcement plate 3 3 is provided at the pipe support position of the high-pressure filter outlet pipe 10, and a pipe reinforcement plate 2 2 is provided on the lower surface of the clean-ring high-pressure pump group main pipe 8 connecting the two clean-ring high-pressure pump group outlet pipes 9, and the pipe reinforcement plate 2 2 corresponds to the pipe reinforcement plate 3 3 and is connected by a support column 4, and the pipe reinforcement plate 2 2 and the pipe reinforcement plate 3 3 are both perpendicular to the support column 4, and the pipe reinforcement plate 1 1 and the pipe reinforcement plate 3 3 are connected by an inclined support column 2 5 to form a firm and stable triangular frame structure, ensuring that the impact of vibration can be effectively reduced in various environments.

[0021] This utility model is a device for reducing vibration caused by factors other than equipment installation. Its core structure includes three sturdy pipe reinforcement plates and two support columns, which cleverly form a stable and strong triangular frame structure. Triangular frame structures are widely recognized in engineering for their excellent stability and support. To further enhance the stability and durability of the structure, support point protection, namely pipe reinforcement plates, are provided at key locations. The lower surface of the main pipeline of the clean ring high-pressure pump unit and the upper surface of the high-pressure filter outlet pipeline are tightly connected by two sturdy support columns, forming a strong and stable triangular frame, ensuring that the impact of vibration can be effectively reduced in various environments.

[0022] The pipe reinforcement plate is designed to further enhance the protection of equipment pipelines, thereby effectively extending their service life. In the specific implementation process, we first conduct a detailed analysis and precise calculation of the pipeline area where three support points need to be welded. Next, we select pipeline materials with a strong texture and moderate wall thickness to ensure that their dimensions perfectly match the original pipeline. On this basis, using professional cutting technology, two square reinforcement plates are precisely cut out, set to twice the diameter of the support column to ensure sufficient coverage and improve structural strength. At the same time, a rectangular reinforcement plate is cut out, the length of which is three times the diameter of the support column, and the width remains consistent with the square reinforcement plate. Finally, the three manufactured pipe reinforcement plates are directly welded to the three pre-designed key points to construct a solid triangular frame that cooperates with the support column to provide all-round, long-lasting and stable protection for the equipment pipeline.

[0023] The position of the pipeline reinforcement plate 1 takes into account the vibration of the outlet pipeline of the clean ring high-pressure pump group. A precise welding point is selected on the lower surface of the clean ring high-pressure pump group main pipeline at the connection position of the clean ring high-pressure pump group outlet pipeline and the clean ring high-pressure pump group main pipeline, where the vibration amplitude is relatively high. Another welding point is set at the position of the clean ring high-pressure pump group main pipeline where the two clean ring high-pressure pump group outlet pipelines intersect; a welding point is set at the pipe support position of the high-pressure filter outlet pipeline, and is vertically connected to the welding point on the lower surface of the clean ring high-pressure pump group main pipeline between the two clean ring high-pressure pump group outlet pipelines through a support column 1. This design forms a stable triangular support structure between the support column and the clean ring high-pressure pump group outlet pipeline with relatively high vibration, thereby improving the seismic resistance and overall stability of the equipment pipeline.

[0024] This new device successfully reduces vibrations caused by equipment that exceed construction standards, not only improving overall equipment efficiency but also effectively extending its service life. Furthermore, it effectively ensures operational safety, significantly reducing potential safety risks. This new device is particularly effective in ensuring safe production in blast furnaces, providing a solid foundation for the company's continued stable operations.

[0025] The utility model reduces the vibration of the unit during operation, ensuring the normal operation of the unit. In special cases, the utility model can reduce the high vibration problem of the unit except for equipment defects, poor alignment and installation problems, and has the characteristics of convenient construction, simple operation and good commissioning effect.
