Description

Technical Field

[0001] The utility model relates to the technical field of noise reduction in air intake and exhaust areas, in particular to a stable array noise reduction unit. Background Art

[0002] Under the premise of the same sound attenuation, array silencers have a larger flow area, a smaller resistance coefficient, a smaller pressure loss, and a higher high-frequency failure cutoff frequency compared to plate silencers. In the past, array silencers were often installed to reduce noise in air inlets and exhaust ports. Since array silencers are usually installed at air inlets and exhaust ports with high air flow velocities, and there is strong airflow at the installation location, high-frequency vibrations of the silencer unit can cause the connection points to fall off or break, causing the silencer column to fall, reducing the sound attenuation, and even damaging the fan equipment. There are certain risks in long-term use.

[0003] A Chinese patent discloses a plate-type silencer (publication number: CN 209540300 U) comprising a seat and a silencer plate. The silencer plate is installed in the inner cavity of the seat and has a avoidance portion. One end of the avoidance portion is located at the outlet of the seat, and the other end is located at a position in the inner cavity where turbulence can be generated. The thickness of the avoidance portion is less than the thickness of the silencer plate. However, this type of silencer has a large flow area and a large resistance coefficient, a large pressure loss, and a low high-frequency failure cutoff frequency. This may cause the high-frequency vibration of the silencer unit, resulting in the connection point falling off or breaking, causing the silencer column to fall, reducing the silencer volume, and even damaging the fan equipment. There are certain risks and other problems during long-term use. Therefore, a stable array silencer unit is needed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art in that the silencer flow area is large, the resistance coefficient is large, the pressure loss is large, and the high-frequency failure cut-off frequency is low during use, which may cause the high-frequency vibration of the silencer unit to cause the connection point to fall off or break, causing the silencer column to fall, the sound attenuation volume to decrease, and even possible damage to the fan equipment, and there are certain risks in the long-term use process. A stable array silencer unit is proposed.

[0005] The technical solution adopted by the present invention to solve its technical problems is: the present invention describes a stable array silencer unit, including a silencer column, characterized in that: the top and bottom of the silencer column are provided with fixing components, the number of the fixing components is 2 groups and they are arranged correspondingly up and down, the fixing components include a guide head, the top center of the guide head is connected to the array silencer square tube frame, the outer wall of the array silencer square tube frame is provided with several types of connecting parts, connecting bolts are provided between the several types of connecting parts and the array silencer square tube frame, fixing screws are provided between the several types of connecting parts and the guide head, and the design of the two groups of corresponding fixing components above and below improves the structural stability of the entire silencer unit, and can remain stable even in harsh environments; improves the silencer efficiency: the stable structure helps to maintain the best working state of the sound-absorbing material, thereby improving the overall silencer effect.

[0006] Preferably, the silencer column is composed of a combination of sound-absorbing material and a perforated plate shell. The sound-absorbing material can effectively absorb the sound passing through the perforated plate and reduce noise transmission. The perforated plate shell not only protects the sound-absorbing material, but also increases the durability and weather resistance of the entire unit. The design of the perforated plate can be customized with different patterns or colors as needed to make the product more attractive.

[0007] Preferably, the sound-absorbing material is made of glass fiber, and the perforated plate shell is made of aluminum alloy. The aluminum alloy shell reduces the overall weight, facilitates installation and transportation, and ensures the strength of the structure. Aluminum alloy has good corrosion resistance and is suitable for long-term use in various harsh environments.

[0008] Preferably, a rotating connection method is adopted between the guide head and the square tube frame of the array silencer. The rotating connection method provides greater flexibility and the direction of the guide head can be adjusted according to actual needs to adapt to different installation environments and requirements. By adjusting the direction of the guide head, the airflow can be better guided into the square tube frame of the silencer, further improving the sound elimination effect.

[0009] Preferably, the specification of the connecting bolt is M10×90, and the specification of the fixing screw is M5.5×35. The standardized fasteners ensure the reliability and stability of the connection, reduce the problems caused by loosening or falling off, and the standardized fasteners are easy to replace and convenient for maintenance and repair.

[0010] Preferably, the several types of connectors are opened on the left and right and the size of the openings is related to the connecting bolts. The material of the several types of connectors is galvanized steel plates. The design of the several types of connectors ensures a close fit with the connecting bolts and improves the stability of the overall structure; corrosion resistance: galvanized steel plate material has good corrosion resistance, is suitable for outdoor environments, and extends service life.

[0011] The utility model is beneficial in that:

[0012] The present application can ensure that the silencer column of the array silencer is stable and does not fall off in a strong airflow environment, effectively reducing the noise damage to the lower fan equipment caused by the silencer column's own shaking due to falling off in an environment of strong airflow and high-frequency vibration of the equipment, optimizing the installation direction of the fixing bolts, avoiding the influence of gravity on the bolts, and efficient sound absorption: the use of efficient sound-absorbing materials, such as glass fiber, can effectively absorb the sound passing through the perforated plate and significantly reduce the noise level. The guide head and the square tube frame of the array silencer are connected in a rotating manner, and the direction of the guide head can be adjusted according to actual needs to adapt to different installation environments and requirements.
