Abstract
The utility model discloses a silencer having a left-built air exhaust outlet facing upwards. The silencer includes a cylindrical shell the bottom end of the cylindrical shell is provided with a first separator plate, a second separator plate and a third separator plate are respectively and transversely arranged in the middle part of the cylindrical shell, a vertical coaming plate is connected with the second separator plate and the third separator plate, plugs are respectively arranged at the upper end and the lower end of the cylindrical shell, an air inlet pipe is connected at the upper end of the cylindrical shell, the outer end of the air inlet pipe is connected with an air inlet joint, a breather pipe penetrates through the second separator plate and the third separator plate, the bottom end of the cylindrical shell is connected with an air outlet pipe, the outer end of the air outlet pipe is connected with an air outlet joint, and a rib plate is arranged between the outer sidewall of the cylindrical shell and the air outlet pipe. The silencer provided is reasonable in structure and design and good in noise abatement effect, if the total area of a nozzle keeps unchanged and the nozzle is replaced by a plurality of small nozzles, the frequency spectrum of air blowing noises can move to high frequency or ultrahigh frequency when air flow passes through the small nozzles, thus the acoustic sounds of the frequency spectrum can be greatly reduced and the interference and harmfulness to human also can be reduced.
Description
Technical field
The utility model relates to the silencing apparatus field, belongs to an a kind of left side more specifically and puts relief opening silencing apparatus up.
Background technique
The baffler of heavy truck is mounted on the heavy truck, links to each other with motor, reduces engine noise.A kind of device that stops sound transmission and allow air communication to cross is the important measures of eliminating air power noise.Baffler is mounted in aerodynamic force equipment, as on the air-flow path of the bigger equipment of relief opening noises such as blower, air compressor, boiler exhaust mouth, generator, water pump or the device of the reduction noise in the inlet and exhaust system.Structure is the straight tube of an endcapped, be drilled with a lot of apertures on the tube wall, the principle of aperture baffler is that frequency spectrum with jet noise is a foundation, replace with a lot of little spouts if the gross area of maintenance spout is constant, when the frequency spectrum of air-flow during through small holes, jet noise will be shifted to high frequency or ultra-high frequency, audible sound composition in the frequency spectrum is obviously reduced, thereby reduce interference and injury the people.Complex structure, noise elimination weak effect in the prior art, situations such as life cycle weak point.
The model utility content
The purpose of this utility model provides an a kind of left side and puts relief opening silencing apparatus up, reasonable in design, and the noise elimination effect is good, has reduced interference and injury to human body, and life cycle is long.
The technical solution of the utility model is as follows:
Relief opening silencing apparatus is up put on an a kind of left side, include cylindrical shell, the bottom of described cylindrical shell is provided with first dividing plate, second, third dividing plate is laterally established at the middle part of described cylindrical shell respectively, be connected with vertical coaming plate between described first dividing plate and the second partition middle part, the upper and lower end of described cylindrical shell is respectively equipped with end socket, described cylindrical shell upper end is connected with suction tude, the suction tude outer end is connected with air input joint, passed breathing pipe on described second, third dividing plate, described cylindrical shell bottom is connected with steam outlet pipe, and the outer end of steam outlet pipe is connected with air outlet adapter.
Be provided with gusset between described cylindrical shell outer side wall and the steam outlet pipe.
The utility model reasonable in design, it is effective to eliminate the noise, replace with a lot of little spouts if the gross area of maintenance spout is constant, when the frequency spectrum of air-flow during through small holes, jet noise will be shifted to high frequency or ultra-high frequency, audible sound composition in the frequency spectrum is obviously reduced, thereby reduce interference and injury to the people, it is also convenient to use.
