Abstract

The utility model discloses a novel silencer, which comprises a barrel with an upper sealing cover and a lower sealing cover, an outlet connecting pipe arranged on the upper sealing cover, and an inlet connecting pipe arranged on the lower sealing cover. A partition board is arranged in the barrel. Two silencing pipes are arranged on the partition board. The silencing pipes and the partition board are arranged in the barrel at a certain inclination angle along a central axis on one side of an air inlet. Silencing materials are wrapped on the barrel. An outlet flange is arranged on the outlet connecting pipe. An inlet flange is arranged on the inlet connecting pipe. An air outlet is reserved in the outlet flange. The air inlet is reserved in the inlet flange. The novel silencer has a rational structure, and is easy to manufacture and good in silencing effect.

Description

Novel baffler
Technical field
The utility model relates to a kind of baffler, especially a kind of novel baffler.
Background technique
Baffler is to stop sound transmission and a kind of device of allowing air communication to cross, is the important measures of eliminating air power noise.Baffler is mounted on the air-flow path of aerodynamic force equipment (like bigger equipment of relief opening noise such as blower, air compressor, boiler exhaust mouth, generator, water pumps) or the device of the reduction noise in the inlet and exhaust system.
The kind of baffler is a lot, but studies carefully its noise elimination mechanism, can be divided into six kinds of main types to them again, promptly resistive baffler, resistant noise-reducing device, impedance complex formula baffler, microperforated panel baffler, aperture baffler and active baffler.
There is unreasonable structure in existing baffler, makes problems such as complicacy and erasure effect difference.
Summary of the invention
The utility model purpose is to provide a kind of rational in infrastructure, model muffler of making simple and good muffling effect.
The technological scheme of the utility model is: comprise the cylindrical shell that has upper cover and following capping, be installed in the discharge connection on the upper cover, be installed in down the entrance sleeve in the capping, dividing plate is installed in cylindrical shell, two hush pipes are installed on dividing plate.
Be enclosed with quieter material on the described cylindrical shell.
Described hush pipe and dividing plate are a fixed inclination in suction port one side along central shaft and are installed in the cylindrical shell, and described angle of bevel is 15~180 degree.
Described discharge connection is provided with outlet(discharge) flange, and entrance sleeve is provided with suction flange, has the air outlet on the outlet(discharge) flange, has suction flange on the suction flange.The utility model is rational in infrastructure, manufacturing is simple and good muffling effect.
