Description

Technical Field

[0001] This utility model relates to the technical field of thermal power plants, and in particular to a boiler compressed air silencer. Background Technology

[0002] A boiler is a device that heats water to high-temperature, high-pressure steam or hot water by burning fuel or using electricity. It is widely used in industrial and building heating, hot water supply, and power generation. The boiler's compressed air system provides power to the equipment, but the release of compressed air generates significant noise, which not only affects operators but also interferes with the normal operation of the equipment. Therefore, silencers are used to reduce noise during air release. Silencers effectively reduce noise generated by gas flow by altering the airflow path and slowing the airflow velocity. Silencers are particularly important when the airflow velocity in the compressed air system is high or the air discharge volume is large. In summary, the use of silencers for compressed air in boilers aims to reduce noise pollution, protect the environment, and improve equipment comfort and stability.

[0003] The working principle of a boiler compressed air silencer is primarily based on reducing noise during the compressed air flow process. When compressed air is released through a pipeline under high pressure, the gas expands rapidly due to the high airflow velocity, generating significant noise. Silencers typically use multiple openings, extended pipes, or sound-absorbing materials to slow down the airflow velocity, change the airflow direction, and reduce the impact force and turbulence of the airflow, thereby reducing noise. Simultaneously, sound-absorbing materials such as foam and cotton cloth are used inside the silencer to absorb sound energy, further reducing sound propagation. Through these methods, boiler compressed air silencers effectively reduce noise, ensuring smoother boiler system operation and minimizing interference with the environment and operators. In summary, boiler compressed air silencers reduce noise by slowing down airflow velocity, changing the airflow path, and using sound-absorbing materials, providing a quieter working environment for the boiler system.

[0004] In existing technologies, some boiler compressed air silencers lack effective anti-clogging mechanisms. This means that when the silencer's internal silencing holes become clogged due to the accumulation of dust, dirt, or other impurities, the silencer's normal function will be affected. Clogging leads to poor airflow, reduces the silencing effect, and may even exacerbate the noise problem. Therefore, a boiler compressed air silencer is proposed to address these issues.

[0005] To overcome the above shortcomings, this utility model provides a boiler compressed air silencer, which aims to improve the problem that some existing boiler compressed air silencers lack anti-clogging mechanisms, causing the silencer holes to become clogged and directly affecting the silencer effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a boiler compressed air silencer, comprising a silencer body, four support legs fixedly connected to the bottom of the silencer body, an air vent pipe fixedly connected to the bottom of the silencer body, a cleaning and filtering mechanism fixedly connected to the bottom of the air vent pipe, and an anti-clogging silencer mechanism rotatably connected inside the silencer body.

[0016] 1. In this utility model, the gas generated by the boiler enters the interior of the silencer body through the air inlet. During this process, the gas pushes the fan blades located inside the air pipe, and then drives the rotating shaft through the fan blades.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 2 , Figure 4 One embodiment of this utility model is a boiler compressed air silencer, which includes a silencer body 1. The silencer body 1 is the core part of the whole device and is responsible for accommodating and supporting the anti-clogging silencer mechanism. The design of the silencer body 1 needs to ensure that it can effectively withstand the pressure of the boiler compressed air during operation, while providing sufficient space and structural stability for easy installation and maintenance. Four support legs 2 are fixedly connected to the bottom of the silencer body 1. The support legs 2 are used to support the silencer body 1 and ensure that the silencer is placed stably on the ground or on a bracket. A vent pipe 11 is fixedly connected to the bottom of the silencer body 1. The vent pipe 11 is a pipe that connects the boiler system and the silencer and is responsible for guiding the compressed air into the silencer. A cleaning and filtering mechanism is fixedly connected to the bottom of the vent pipe 11. The cleaning and filtering mechanism is used to clean impurities, dust, oil and other substances in the boiler system and prevent impurities, dust and oil from entering the silencer and clogging the silencer holes. An anti-clogging silencer mechanism is rotatably connected inside the silencer body 1. The main function of the anti-clogging silencer mechanism is to prevent the silencer holes from being blocked by the accumulation of dirt, which would affect the silencer effect. An installation groove is opened inside the silencer body 1, and the sound-absorbing block 9 is fixedly connected to the inside of the installation groove.

[0026] The anti-clogging silencing mechanism includes a rotating shaft 7, which is located inside the muffler body 1 and connected to a cleaning block 8. The rotating shaft 7 can drive the cleaning block 8 to rotate inside the muffler. The external part of the rotating shaft 7 is rotatably connected to the inside of the muffler body 1. The top of the rotating shaft 7 is fixedly connected to the cleaning block 8, which is located inside the muffler and is used to clean dirt or impurities around the silencing holes to prevent clogging. The muffler body 1 has a cavity inside, and a sound-absorbing block 9 is fixedly connected inside the cavity. The sound-absorbing block 9 can enhance the sound absorption effect when the air passes through the muffler, thereby effectively reducing noise. The external part of the cleaning block 8 is rotatably connected to the inside of the cavity. The muffler body 1 has multiple silencing holes inside. The number and arrangement of the silencing holes directly affect the silencing effect. The external part of the rotating shaft 7 is fixedly connected to multiple flow rate buffer components. The cleaning block 8 adopts a ramp design in the counterclockwise direction. Both the inner and outer walls of the cleaning block 8 are in contact with the cavity inside the muffler body 1.

[0027] The flow rate buffer assembly includes multiple deceleration funnels 6. These funnels 6 are used to reduce the flow rate of compressed air, preventing excessively fast airflow from generating severe noise. The deceleration funnels 6 are externally fixedly connected to the inside of the muffler body 1. Multiple scrapers 14 are externally fixedly connected to the rotating shaft 7. The scrapers 14 contact the deceleration funnels 6, mechanically scraping away impurities in the air to prevent clogging the muffler's interior. The top of the scrapers 14 contacts the bottom of the deceleration funnels 6. A buffer shaft 5 is externally fixedly connected to the rotating shaft 7. The deceleration funnels 6 and buffer shaft 5 help slow down the flow rate of compressed air, reducing noise sources. The design of the deceleration funnels 6 allows the airflow to gradually expand, reducing the impact force of the airflow. The top of the scrapers 14 contacts the bottom of the buffer shaft 5. Multiple through holes are opened inside the deceleration funnels 6, which are funnel-shaped blocks, wider at the top and narrower at the bottom. Multiple air vents are opened inside the buffer shaft 5.

[0028] Reference Figure 1 , Figure 3 The cleaning and filtration mechanism includes a filter box 4, which is located at the bottom of the vent pipe 11 and is responsible for collecting and storing filter materials and dust. The top of the filter box 4 is fixedly connected to the bottom of the vent pipe 11. A filter mounting block 12 is slidably connected inside the filter box 4. The filter mounting block 12 is installed inside the filter box 4 to facilitate sliding and installing the filter plate 13. The design of the filter mounting block 12 allows for easy disassembly and cleaning of the filter plate 13. The filter plate 13 is slidably connected inside the filter mounting block 12. The filter plate 13 is the part of the silencer that directly contacts the vent pipe 11 and is responsible for filtering impurities in the air. The bottom of the vent pipe 11 contacts the top of the filter plate 13. An air inlet 3 is fixedly connected to the front of the filter box 4 and contacts the boiler outlet. A sliding groove is provided inside the filter box 4. The filter mounting block 12 is slidably connected to the inside of the sliding groove. Guide grooves are provided on the left and right sides of the sliding groove. Guide blocks are provided on the left and right sides of the filter mounting block 12. The guide blocks are slidably connected to the inside of the guide groove. Multiple fan blades 10 are fixedly connected to the outside of the rotating shaft 7. The fan blades 10 are rotating parts inside the silencer. Their function is to generate wind power by rotating, which helps to accelerate airflow and carry away dust or impurities inside. The multiple fan blades 10 are rotatably connected to the inside of the vent pipe 11.

[0029] Working principle: The gas generated by the boiler flows to the filter box 4 through the air inlet 3. Then, the filter mounting block 12, which is slidably connected to the filter box 4, is responsible for accumulating large impurities in the air. At the same time, the filter plate 13, which is slidably connected to the filter mounting block 12, is responsible for coarse filtration of the air. Then, the air drives the fan blade 10 located inside the air pipe 11 through the vent pipe 11 at the top of the filter box 4 to rotate. Then, the fan blade 10 drives the rotating shaft 7 to rotate. Finally, the scraper 14 and the cleaning block 8, which are fixed outside the rotating shaft 7, scrape the silencing holes inside the silencer body 1 and the through holes inside the speed reduction funnel 6, thereby achieving the function of preventing blockage.

[0030] The through-hole inside the deceleration funnel 6 reduces the airflow velocity, thereby reducing the sound generated when the air passes through the silencer hole, thus improving the silencer effect. In addition, the sound-absorbing block 9 fixed inside the silencer body 1 absorbs the noise generated inside the silencer body 1, further improving the silencer effect.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
