Abstract
The invention discloses a novel silencer, which comprises a cylinder body provided with an upper sealing cover and a lower sealing cover, an outlet joint pipe mounted on the upper sealing cover, and an inlet joint pipe mounted on the lower sealing cover, wherein a baffle plate is mounted in the cylinder body; two silencing pipes are mounted on the baffle plate; the silencing pipes and the baffle plate are mounted in the cylinder body at a certain oblique angle along a central shaft on one side of an air inlet; a silencing material is wrapped on the cylinder body; an outlet flange is arranged on the outlet joint pipe; an inlet flange is arranged on the inlet joint pipe; an air outlet is formed in the outlet flange; and an air inlet is formed in the inlet flange. The novel silencer is reasonable in structure, simple in manufacturing and good in silencing effect.
Description
Technical field
The present invention relates to a kind of baffler, especially a kind of Novel muffler.
Background technique
Baffler is to stop sound transmission and a kind of device of allowing air-flow to pass through, is the important measures of eliminating air power noise.Baffler is mounted in the low noise device that falls on the air-flow path of aerodynamic force equipment (such as larger equipment of relief opening noise such as blower, air compressor, boiler exhaust mouth, generator, water pumps) or 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, i.e. resistive muffler, resistant noise-reducing device, impedance complex formula baffler, microperforated panel baffler, aperture baffler and active baffler.
There is unreasonable structure in existing baffler, make the problems such as complexity and erasure effect is poor.
Summary of the invention
The object of the invention is to provide a kind of rational in infrastructure, model muffler of making simple and good muffling effect.
Technological scheme of the present invention is: comprise with the cylindrical shell of upper cover and lower capping, be installed in the discharge connection on the upper cover, be installed in the entrance sleeve that lower seal covers, dividing plate is installed in cylindrical shell, at dividing plate two hush pipes are installed.
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 ℃.
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.
