Sheet type efficient silencer

Abstract

The invention discloses a sheet type efficient silencer. The sliencer comprises a mounting shell and a mounting bracket, the mounting bracket is fixed in the mounting shell in the vertical direction through expansion bolts or bolts or by welding; a first-type sheet silencing body and a second-type sheet silencing body are arranged on the mounting bracket; each of the first-type sheet type silencing body and the second-type sheet type silencing body is composed of a silencing framework, flow guide covers and silencing cotton, the silencing frameworks are filled with the silencing cotton, the flow guide covers are welded to the two ends, in the airflow direction, of each silencing framework, reinforcing supports are transversely welded to the two ends of an inlet and an outlet of the mounting shell, and protective grids are fixed to the two ends of the inlet and the outlet of the mounting shell through bolts. The sheet type efficient silencer has the beneficial effects that the effectivesilencing area is increased by adopting the sheet type silencing body, the sheet type efficient silencer is simple to install and transport and attractive in appearance, and the silencing effect canbe improved; due to the fact that the concave-convex parts between every two adjacent sheet type silencing bodies are arranged in a staggered mode, the circulation rate of the noise elimination cavityis guaranteed, and noise elimination is facilitated.

Description

Technical field [0001] The invention relates to the field of noise reduction and noise reduction equipment, in particular to a sheet-type high-efficiency muffler. Background technique [0002] The muffler is a device that allows airflow to pass through, but can prevent or reduce sound propagation, and is an important measure to eliminate aerodynamic noise. The muffler can block the propagation of sound waves and allow airflow to pass through, and is an effective tool for noise control. [0003] The noise reduction area of ​​the traditional muffler is purely four-sided, and the area is relatively small. The processing technology of the similar chip muffler is relatively simple. The muffler frame usually adopts a whole plane perforated plate, and an unobstructed muffler cavity is formed between two adjacent mufflers. The effective area of ​​muffler is less. The sound effect needs to be improved, especially the noise reduction treatment at the air inlet or outlet with large diameter...

Problems solved by technology

The processing technology of the similar chip muffler is relatively simple. The muffler skeleton usually adopts a whole flat punching plate, and an unobstructed muffler cavity is formed between two adjacent mufflers. The effective area of ​​muffler is small, and the muffler The sound effect needs to be improved, especially in the muffler treatment of the air inlet or outlet with a large diameter and large air volume, which often fails to meet the actual muffler requirements.
