[0003] The noise of large equipment is mainly medium and high frequency, which can cause noise pollution to the working environment and harm the personal health of the operating personnel. Therefore, various large devices for atmospheric air suction generally need to be provided with a silencer to reduce the noise transmitted by air flow.

The sound absorption reflection plate is located in front of the pipe opening of the fan inlet pipe, and the first sound absorption plate is located on the side of the sound absorption reflection plate close to the fan inlet pipe. The first end of the first sound absorption plate is connected with the sound absorption reflection plate, and the second end of the first sound absorption plate is open and covers the outside of the fan inlet pipe. The sound absorption sound insulation device absorbs and dissipates energy through the sound absorption reflection plate, and further absorbs and dissipates energy through the first sound absorption plate in the possible reflection direction of sound. Noise can be absorbed by multiple reflections, and the sound absorption sound insulation effect is good, which can effectively reduce noise.

[0005] The sound absorption sound insulation device described in the above patent performs sound wave impact on the noise in the air suction equipment through the silencer, which causes energy loss, thereby reducing the noise generated by the air suction equipment. Although the above method can meet the absorption and blocking of the noise of the air suction equipment, the silencer cannot quickly attract and soundproof the noise generated at the original silencer when the device is used. At the same time, when the sound insulation material is used, the device is in a sealed state, which causes the device to be unable to dissipate heat, and the long-term high-temperature environment can easily cause damage to the internal components, greatly reducing the practicability of the device.
