Problems solved by technology

[0002] Existing motor inlet and outlet airflow noise elimination devices mostly use resistive, resistive, micro-perforated or rent-resistant composite pipe mufflers, which have complex structures, cumbersome production, large pressure loss, weak noise reduction effect per unit length, and single-body mufflers. Product quality is heavy, therefore, has certain disadvantages

Abstract

The invention relates to a perforated plate muffler which includes a perforated plate and an airflow guiding device. The perforated plate muffler is characterized in that the outer walls of the perforated plate are provided with sound-absorbing cotton, the outer sides of the sound-absorbing cotton are provided with corrosion-resistant boards, and the airflow guiding device is adhered to the perforated plate through adhesive. By utilizing a composite structure design, combined with the usage of glass fiber reinforced plastic materials which have high strength and light weight and are corrosion-resistant, the perforated plate muffler can be assembled quickly, and is simple in structure, low in resistance coefficient and good in sound insulation effect.

Description

technical field [0001] The invention relates to a muffler, especially a perforated plate muffler. Background technique [0002] Existing motor inlet and outlet airflow noise elimination devices mostly use resistive, resistive, micro-perforated or rent-resistant composite pipe mufflers, which have complex structures, cumbersome production, large pressure loss, weak noise reduction effect per unit length, and single-body mufflers. Product quality is heavy, therefore, has certain disadvantages. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a perforated plate muffler which is simple to manufacture, convenient to maintain and reliable in operation. [0004] The technical solution adopted by the present invention to solve the technical problem is: a perforated plate muffler, including a perforated plate and an airflow guiding device, characterized in that: the outer wall of the perforated plate is provided with soun...
