The invention belongs to the technical field of resistive silencers, and particularly discloses a sectional resistive ventilation silencer and an assembly method thereof, and the sectional resistive ventilation silencer comprises a first silencer body and a second silencer body; the opposite ends of the first silencer body and the second silencer body are connected through a middle piece. The first silencer body and the second silencer body are each provided with a fixing piece, and the two fixing pieces are connected through a connecting piece. The fixing part comprises an upper arc-shaped clamping plate and a lower arc-shaped clamping plate which are correspondingly arranged up and down, an upper lug plate is fixedly connected to the outer side of the upper arc-shaped clamping plate, a fixing plate is arranged at the top of the upper arc-shaped clamping plate, and a through hole is formed in the fixing plate; a through groove is formed in the position, above the through hole, of the fixing plate, a mounting hole is formed in the top of the fixing plate, and a first fastening bolt is movably arranged in the mounting hole; the outer side of the lower arc-shaped clamping plate is fixedly connected with a lower lug plate, and the lower lug plate and the upper lug plate are fixedly connected through a second fastening bolt. Silencers with different lengths can be assembled according to use requirements.
Description
technical field [0001] The invention relates to the technical field of resistive mufflers, in particular to a segmented resistive ventilation muffler and an assembling method thereof. Background technique [0002] A resistive muffler is a device that prevents sound from propagating and allows airflow to pass through, and is an important measure to eliminate aerodynamic noise. Resistive mufflers mainly use porous sound-absorbing materials to reduce noise. The sound-absorbing material is fixed on the inner wall of the airflow channel or arranged in the pipeline in a certain way, and the sound energy is converted into heat energy and dissipated due to friction, so that the noise propagating along the pipeline is attenuated with the distance, so as to achieve the purpose of muffler. , which constitutes a resistive muffler. [0003] When the existing resistive muffler is used, it is inconvenient for users to assemble mufflers of different lengths according to the needs of use, ...
