[0002] In industrial production, compressed air, as an efficient and reliable power source, is widely used to drive various pneumatic tools and equipment; and compressed air pipelines, as the medium for this power transmission, play a vital role. They are widely laid in industrial production lines, construction sites and agricultural machinery and equipment to ensure the stable delivery of compressed air.
[0003] However, when compressed air pipelines are actually used, the compressed air will generate significant noise when flowing at high speed in the pipeline, which not only affects the hearing health of the operators, but may also disturb the tranquility of the surrounding environment and even mask the working signals of important equipment, bringing certain hidden dangers to safe production. It has technical defects such as high noise and strong impact. Traditional methods mostly use passive noise reduction measures such as increasing the pipe wall thickness and using sound-absorbing materials, but these methods often have limited effects, and increasing the pipe wall thickness and adding sound-absorbing materials have the problem of high cost. Therefore, an economical and practical noise-reducing compressed air pipeline is provided. Utility Model Content

[0031] The following is combined with Figure 1-4 This application is described in further detail.
[0032] The embodiment of the present application discloses a noise-reducing compressed air pipeline. Figure 1 The noise reduction compressed air pipeline includes a pipeline body 1. The interior of the pipeline body 1 is a hollow structure. The hollow structure can ensure the normal use of the pipeline, thereby ensuring normal compressed air transmission work.
[0033] Reference Figure 1Flanges 7 are fixedly installed on the outer walls of the two ends of the pipe body 1. The integrated flange 7 connector can effectively improve the pipe connection effect between the compressed air pipes, thereby increasing the laying and installation speed of the compressed air pipes. It has good practicality, and the pipe connection is convenient, fast and practical.
[0034] Reference Figure 1 and Figure 2 A number of reinforcing holes 2 are provided in the pipe body 1. The reinforcing holes 2 are provided along the length direction of the pipe body 1. The reinforcing holes 2 are distributed in a circle with equal intervals along the center point of the pipe body 1. A reinforcing rib 3 is fixedly inserted in each reinforcing hole 2. The reinforcing rib 3 can effectively improve the internal structural strength of the pipe body 1, so that it has better pressure resistance, can effectively resist external impact force, avoid deformation of the pipe due to external force, improve the overall use strength and service life of the pipe, and has better pressure and impact resistance.
[0035] Reference Figure 1 and Figure 2 In order to ensure the lightweight use of the reinforcing ribs 3 in this embodiment, the material used for the reinforcing ribs 3 is aluminum alloy. The reinforcing ribs 3 made of aluminum alloy not only have strong impact resistance structural strength when used, but also have a lighter weight, which can effectively reduce the overall weight of the pipe body 1, thereby achieving a lightweight and high-strength use effect.
[0036] Reference Figure 2 and Figure 3 The outside of the pipe body 1 is wrapped with a jacket 8, and a thermal insulation material layer 4 is filled between the jacket 8 and the pipe body 1. In this embodiment, the thermal insulation material layer 4 can be a thermal insulation material such as rock wool, mineral wool, polyurethane foam, etc. The thermal insulation material layer 4 can effectively perform external thermal insulation treatment on the compressed air pipe, effectively avoiding the condensation of water in the pipe when the compressed air pipe is used in an environment with low temperature in winter, and has a certain thermal insulation effect, thereby improving the use effect of the pipe.
[0037] Reference Figure 2 and Figure 3 A vacuum outer layer 5 is fixedly installed on the outside of the jacket 8, and a vacuum air nozzle 9 is installed on the vacuum outer layer 5. The bottom end of the vacuum air nozzle 9 is inserted between the vacuum outer layer 5 and the jacket 8; the vacuum air nozzle 9 performs vacuum treatment to make it in a vacuum state. When the compressed air pipeline is transporting high-pressure air, the outside of the pipeline is in a vacuum state, so that the noise can be effectively reduced through the vacuum state.
[0038] Reference Figure 4A number of fixed lifting ears 6 are welded and fixed on the vacuum outer layer 5, and the fixed lifting ears 6 are evenly spaced along the central point of the pipe body 1, which can facilitate the lifting of the compressed air pipe. This can facilitate the overall transportation, transfer or handling of the compressed air pipe, improve the convenience of lifting the compressed air pipe, and have good practical effect.
[0039] Reference Figure 4 A lifting hole 61 is provided on any fixed lifting ear 6. In this embodiment, the lifting hole 61 is designed as a through-hole structure. As a through-hole structure, the lifting hole 61 is convenient for the lifting tool to quickly and accurately penetrate and fix the pipeline, which not only improves the safety of the lifting operation, but also reduces the risk of accidents caused by improper operation.
[0040] The implementation principle of a noise-reducing compressed air pipeline in an embodiment of the present application is as follows: when the compressed air pipeline needs to be noise-reduced, the vacuum equipment is started, and the vacuum air nozzle 9 is used for vacuum treatment to put it in a vacuum state. Since sound is a mechanical wave, its sound propagation needs to be transmitted through a medium (such as air, water, solid, etc.), so sound cannot vibrate in a vacuum. Since there is no medium in a vacuum, sound cannot propagate in a vacuum. When the compressed air pipeline is carrying high-pressure air, the outside of the pipeline is in a vacuum state, so that the noise can be effectively reduced through the vacuum state to reduce the impact of noise; through the arrangement of the outer jacket 8, the vacuum outer layer 5 and the vacuum air nozzle 9, vacuum noise reduction has the technical characteristics of low cost and good noise reduction effect compared with traditional noise reduction means, which can effectively reduce the noise reduction cost of the compressed air pipeline, reduce the maintenance and repair cost of the compressed pipeline, improve the economic effect of the enterprise, and effectively improve the noise reduction effect.
[0041] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
