Description

Technical Field

[0001] This utility model relates to the field of silencer technology, and in particular to a novel pressure swing adsorption oxygen generation silencer device. Background Technology

[0002] The existing new type of pressure swing adsorption (PSA) oxygen generator silencer is a device used to eliminate noise for PSA oxygen generators. When PSA oxygen generators are working normally, they need to discharge a large amount of waste gas into the atmosphere. During the discharge, the instantaneous discharge of high-pressure gas into the atmosphere will generate a relatively large airflow noise. Therefore, the exhaust port needs to be silenced to maintain a good working environment.

[0003] However, when it is used, it only relies on simple spatial changes or sound-absorbing materials to reduce noise. Without a multi-layered porous structure to buffer, divert, and interfere with the airflow, the noise reduction effect is limited. Moreover, it does not have a structure to absorb and dissipate sound wave energy. Relying solely on its own materials and structure, it is difficult to reduce the noise generated by device vibration caused by changes in gas pressure. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a novel pressure swing adsorption (PSA) oxygen generator silencer device. After the exhaust gas enters the silencer sleeve, it first enters the innermost honeycomb pores through the air inlet on the inner wall, and then gradually passes outward through multiple rings of honeycomb pores and connecting holes. The multiple rings of honeycomb pores, together with the connecting holes, can buffer and divert the airflow multiple times, so that the airflow pressure is evenly distributed, which can avoid direct impact and high-speed jet of gas. When the gas flows in the honeycomb pore structure, the sound waves of different paths will interfere with each other and cancel each other out, thereby reducing the noise intensity and achieving noise reduction. The piston will generate a certain displacement under the action of exhaust gas pressure. The buffer spring and buffer damper at the rear end will absorb the vibration energy of the piston, which can effectively reduce the vibration of the device caused by the change of gas pressure, thereby reducing the noise generated by vibration. In addition, the spring and damper can also absorb and dissipate sound waves, further enhancing the silencing effect.

[0013] Compared with existing technologies, this novel pressure swing adsorption (PSA) oxygen generator silencer device, after the exhaust gas enters the silencer sleeve, first enters the innermost honeycomb structure through the air inlet on the inner wall, and then gradually passes outward through multiple rings of honeycomb structure and connecting holes. The multiple rings of honeycomb structure and connecting holes can buffer and divert the airflow multiple times, so that the airflow pressure is evenly distributed. This can avoid direct impact and high-speed jet of gas. When the gas flows in the honeycomb structure, the sound waves of different paths will interfere with each other and cancel each other out, thereby reducing the noise intensity and achieving noise reduction. The piston will generate a certain displacement under the action of exhaust gas pressure. The buffer spring and buffer damper at the rear end will absorb the vibration energy of the piston. This can effectively reduce the vibration of the device caused by changes in gas pressure, thereby reducing the noise generated by vibration. In addition, the spring and damper can also absorb and dissipate sound waves, further enhancing the silencing effect. Attached Figure Description

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4 This utility model discloses a novel pressure swing adsorption oxygen generator silencer device, comprising: a silencer sleeve 9, an upper connecting plate 2 fixedly connected to the upper surface of the silencer sleeve 9, a lower connecting plate 6 fixedly connected to the lower surface of the silencer sleeve 9, a spring 8 fixedly connected to the upper surface of the upper connecting plate 2, a damper 7 fixedly connected to the upper surface of the upper connecting plate 2, a spring 11 fixedly connected to the lower surface of the lower connecting plate 6, a damper 10 fixedly connected to the lower surface of the lower connecting plate 6, a top plate 1 fixedly connected to the upper ends of the spring 8 and the damper 7, a bottom plate 23 fixedly connected to the lower ends of the spring 11 and the damper 10, a support rod 20 fixedly connected between the top plate 1 and the bottom plate 23, and a mounting plate 21 fixedly connected to the side surface of the bottom plate 23, with mounting holes 22 provided on the mounting plate 21.

[0023] Specifically: The silencer sleeve 9 is connected to spring 8, damper 7, spring 11, and damper 10 via the upper connecting plate 2 and the lower connecting plate 6 respectively. The structure composed of the top plate 1, the bottom plate 23, and the support rod 20 provides stable support for the entire silencer device. Spring 8, damper 7, spring 11, and damper 10 not only play a supporting role, but also absorb the vibration generated by the silencer sleeve 9 during operation to a certain extent, preventing the vibration from being transmitted to other parts, and further ensuring the stability of the equipment operation and the silencing effect.

[0024] One end of the silencer sleeve 9 is connected to the oxygen generator connecting pipe 3. The outer wall of the oxygen generator connecting pipe 3 is fixedly connected to the connecting flange 4. The connecting flange 4 is provided with a connecting hole 19. One end of the oxygen generator connecting pipe 3 is fixedly connected to the sealing ring 5.

[0025] Specifically: the exhaust gas generated by the pressure swing adsorption oxygen generator enters the silencer sleeve 9 through the oxygen generator connecting pipe 3. The connecting flange 4 and the connecting hole 19 are used to connect and fix the oxygen generator connecting pipe 3 to the exhaust gas outlet of the oxygen generator. The sealing ring 5 plays a sealing role to ensure that all the exhaust gas enters the silencer sleeve 9 without leakage.

[0026] The muffler sleeve 9 has multiple honeycomb holes 15 arranged in four rings, and a connecting hole 16 is provided between the multiple honeycomb holes 15. The inner wall of the muffler sleeve 9 has multiple air inlets 17, which are connected to the innermost honeycomb holes 15. The outer wall of the muffler sleeve 9 has multiple exhaust ports 14, which are connected to the outermost honeycomb holes 15.

[0027] Specifically: Exhaust gas enters the innermost honeycomb pores 15 through multiple air inlets 17 on the inner wall of the silencer sleeve 9. Since the honeycomb pores 15 are arranged in four rings and have interconnecting holes 16, the exhaust gas will be gradually transmitted outward in the multi-layer honeycomb pore structure. During this process, the airflow will be buffered and diverted multiple times, so that the airflow pressure is evenly distributed, avoiding direct impact and high-speed jet of gas, reducing the noise generated by gas emission. When the gas flows in the honeycomb pores 15, the sound waves of different paths will interfere with each other and cancel each other out, thereby reducing the noise intensity and achieving the noise reduction effect. After being buffered and noise-reduced by the honeycomb pore structure, the exhaust gas is finally discharged through multiple exhaust ports 14 on the outer wall of the silencer sleeve 9 and enters the atmosphere or subsequent treatment system.

[0028] A buffer spring 12 is fixedly connected to the inner surface of the muffler sleeve 9, and a buffer damper 13 is fixedly connected to the inner surface of the muffler sleeve 9. A piston 18 is fixedly connected to the other end of the buffer spring 12 and the buffer damper 13.

[0029] Specifically: Under the action of exhaust gas pressure, piston 18 will produce a certain displacement. The buffer spring 12 and buffer damper 13 connected to piston 18 will absorb the vibration energy of piston 18, effectively reducing the vibration of muffler sleeve 9 caused by gas pressure changes, thereby reducing the noise generated by vibration. At the same time, buffer spring 12 and buffer damper 13 can also absorb and dissipate sound waves, further enhancing the muffler effect.

[0030] Working principle: During use, the connecting flange 4 and connecting hole 19 are used to connect and fix the oxygen generator connecting pipe 3 to the exhaust port of the oxygen generator. After the exhaust gas enters the silencer sleeve 9, it will enter the innermost honeycomb hole 15 through multiple air inlets 17 on the inner wall of the silencer sleeve 9. Since the honeycomb hole 15 is set with four rings and interconnected with each other through holes 16, the exhaust gas will be gradually transmitted outward in the multi-layer honeycomb hole structure. During this process, the airflow will be buffered and diverted multiple times, so that the airflow pressure is evenly distributed, avoiding direct impact and high-speed jet of gas, and reducing the noise generated by gas emission. When the gas flows in the honeycomb hole 15, the sound waves of different paths will interfere with each other and cancel each other out, thereby reducing the noise intensity and achieving the noise reduction effect. After being buffered and noise-reduced by the honeycomb hole structure, the exhaust gas is finally discharged through multiple exhaust ports 14 on the outer wall of the silencer sleeve 9 and enters the atmosphere or subsequent treatment system.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
