Description

Technical Field

[0001] This utility model relates to the field of array-type silencers, and in particular to the trapezoidal reflective sound absorber of the array-type silencer. Background Technology

[0002] Ventilation and air conditioning systems are core supporting facilities in modern buildings, widely used in various scenarios such as subways, residential buildings, commercial buildings, and industrial plants. The noise generated during their operation directly affects the indoor and outdoor acoustic environment, and noise control has become an important technical requirement in this field. As the mainstream noise control equipment in ventilation and air conditioning systems, array silencers rely on sound absorbers as the core component for achieving their noise reduction function. Their structural design is closely related to system adaptability. As the construction industry continues to increase its requirements for acoustic environment quality, equipment installation convenience, and long-term stability, the shortcomings of traditional sound absorbers are becoming increasingly prominent, making it difficult to meet practical application needs.

[0003] In existing traditional silencers, sound waves often pass through the sound-absorbing structure once and are then discharged, resulting in insufficient absorption and attenuation.

[0004] To address this, an array-type silencer with a trapezoidal reflective sound absorber is proposed. Utility Model Content

[0005] In view of this, the present invention aims to provide an array-type muffler trapezoidal reflective sound absorber to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial alternative.

[0006] The technical solution of this utility model embodiment is implemented as follows: the array-type silencer trapezoidal reflective sound absorber includes a main body structure, which includes: a galvanized perforated plate, metal plates disposed on both sides of the galvanized perforated plate, a galvanized steel plate disposed on one side of the metal plate, perforations disposed on both sides of the galvanized perforated plate, wear-resistant rings disposed on both sides of the galvanized perforated plate, ultrafine centrifugal glass wool disposed inside the galvanized perforated plate, trapezoidal reflective steel plates disposed on both sides inside the ultrafine centrifugal glass wool, sound-absorbing perforated plates disposed on both sides of the trapezoidal reflective steel plates, openings disposed inside the sound-absorbing perforated plates, and a glass fiber cloth outer covering layer disposed on the outer wall of the ultrafine centrifugal glass wool.

[0007] In some embodiments, mounting plates are provided at the top and bottom of the galvanized perforated plate, and a rubber plate is provided on one side of the mounting plate.

[0008] In some embodiments, a maintenance plate is provided on one side of the mounting plate, and a fixing bolt is provided on the other side of the mounting plate.

[0009] The present invention has the following advantages due to the adoption of the above technical solution: The array-type silencer uses a trapezoidal reflective sound absorber. When working, sound waves first enter the interior through the openings of the perforated plate and sound-absorbing plate. The ultra-fine centrifugal glass wool absorbs the sound waves, and the trapezoidal reflective steel plate reflects the sound waves back to the glass wool area. This process allows the sound waves to be absorbed and attenuated multiple times. The coordinated action of each component allows the sound waves to fully function inside, thereby effectively improving the sound absorption effect.

[0010] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0014] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0015] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0016] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0017] Example 1: like Figures 1-4 As shown, the array-type silencer trapezoidal reflective sound absorber includes a main body 100, which includes: a galvanized perforated plate 101, metal plates 102 installed on both sides of the galvanized perforated plate 101, a galvanized steel plate 103 installed on one side of the metal plate 102, perforations 104 opened on both sides of the galvanized perforated plate 101, wear-resistant rings 105 installed on both sides of the galvanized perforated plate 101, ultrafine centrifugal glass wool 109 filled inside the galvanized perforated plate 101, trapezoidal reflective steel plates 110 installed on both sides inside the ultrafine centrifugal glass wool 109, sound-absorbing perforated plates 111 installed on both sides of the trapezoidal reflective steel plates 110, openings 112 opened inside the sound-absorbing perforated plates 111, and a glass fiber cloth outer covering 113 wrapped around the outer wall of the ultrafine centrifugal glass wool 109.

[0018] In this embodiment, mounting plates 106 are installed on the top and bottom of the galvanized perforated plate 101. A rubber plate 107 is adhered to one side of the mounting plate 106, and a maintenance plate 108 is installed on one side of the mounting plate 106. A fixing bolt is threaded to the other side of the mounting plate 106. This not only ensures the sealing of the connection between the sound absorber and the silencer body to prevent noise leakage, but also greatly facilitates the maintenance of the internal sound-absorbing components and extends the service life of the sound absorber.

[0019] In this embodiment: when working, the sound wave first enters the interior through the opening 112 of the perforated plate 111 and the transparent grid 104. The ultrafine centrifugal glass wool 109 absorbs the sound wave, and the trapezoidal reflective steel plate 110 reflects the sound wave back to the glass wool area, so that the sound wave is absorbed and attenuated multiple times. The various components work together to allow the sound wave to fully play inside, thereby effectively improving the noise reduction effect.

[0020] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
