Description
Technical Field
[0001] The utility model relates to the technical field of pipeline silencers, in particular to a barrier-type pipeline silencer. Background Art
[0002] The barrier type pipe silencer is a silencer that uses sound absorbing materials to absorb noise. Its working principle is to fix the sound absorbing materials on the inner wall of the airflow channel or arrange them in the pipe in a certain way, and convert the sound energy into heat energy and dissipate it through friction resistance and viscosity, so as to achieve the purpose of noise reduction. This type of silencer is particularly suitable for situations with large air volume and large pipes, because it can divide the large pipe into multiple smaller noise reduction channels, which not only maintains a larger airflow channel, but also increases the circumference of the sound absorbing material in the airflow channel, thereby improving the noise reduction effect.
[0003] At present, when silencing a pipeline, the sound emitted by the pipeline is generally reduced by using sound-absorbing materials. Although the sound-absorbing materials have good sound-absorbing effects, the sound-absorbing materials inside the silencer are prone to absorb a large amount of water vapor. After the sound-absorbing materials are affected by water vapor, the sound-absorbing performance is easily reduced or the material is damaged, which reduces the service life. At the same time, the sound-absorbing materials need to be replaced regularly and frequently. Therefore, a barrier-type pipeline silencer is proposed. Utility Model Content

[0025] A fixing ring 8 is fixedly installed on the right outer wall of the glass wool felt 6. The glass wool felt 6 is cylindrical in shape. The diameter of the fixing ring 8 is the same as the diameter of the glass wool felt 6. The distance between the pipe 1 and the air duct 5 is the same as the thickness of the glass wool felt 6. The inner wall and the outer wall of the glass wool felt 6 are slidingly connected to the outer wall of the air duct 5 and the inner wall of the pipe 1 respectively. Two clamping seats 9 are fixedly installed on the right outer wall of the fixing ring 8. A sealing ring 10 is movably installed on the right outer wall of the pipe 1. Two clamping grooves are opened on the left outer wall of the sealing ring 10. The clamping seat 9 is clamped in the inside of the clamping groove and the size is adapted. The diameter of the sealing ring 10 is the same as the diameter of the pipe 1, and the inner diameter of the sealing ring 10 is the same as the inner diameter of the air duct 5.
[0026] Two mounting seats 11 are fixedly installed on the outer peripheral wall of the sealing ring 10, two fixing seats 12 are fixedly installed on the outer peripheral wall of the pipe 1, bolts 13 are movably installed inside the mounting seats 11, mounting holes are opened inside the mounting seats 11, threaded holes are opened inside the fixing seats 12, the bolts 13 are slidably connected to the mounting holes and threadedly connected inside the threaded holes and are of matching sizes, two mounting rods 14 are fixedly installed on the outer peripheral wall of the sealing ring 10, three rubber rings 15 are fixedly installed on the outer peripheral wall of the pipe 1, and four connecting rods 16 are fixedly installed between the three rubber rings 15.
[0027] In this embodiment, the air guide plate 7 blocks the water vapor in the pipeline 1, which greatly reduces the adsorption of water vapor in the pipeline 1 by the glass wool felt 6 and reduces the number of times the glass wool felt 6 needs to be replaced.
[0028] In this embodiment, the gas guide seat 4 guides the gas in the pipeline 1 so that all of the gas is input into the interior of the gas guide pipe 5 .
[0029] In this embodiment, the glass wool felt 6 has a loose internal structure and a relatively large overall density, and can absorb and emit sound in a timely manner, thereby effectively reducing environmental noise.

[0031] The working principle of the above embodiment is:
[0032] After the air with water vapor is input into the interior of the pipe 1, the water vapor and air are input into the interior of the air guide pipe 5 through the air guide seat 4 and the mounting ring 3. At this time, due to the action of the air guide plate 7, the water vapor cannot directly contact the glass wool felt 6. At the same time, the noise in the pipe 1 is absorbed through the sound-absorbing holes. At the same time, the vibration and noise of the pipe 1 are absorbed through the action of the rubber ring 15. When the glass wool felt 6 needs to be replaced, the bolt 13 is removed from the inside of the mounting seat 11 and the fixing seat 12, and then the sealing ring 10 is removed from the right side of the pipe 1. At this time, the card seat 9 is pulled to remove the glass wool felt 6 from the inside of the pipe 1. At this time, the rubber ring 15 is removed from the outer wall of the pipe 1 through the mounting rod 14, and the glass wool felt 6 can be replaced.
