Description
Technical field
The utility model is related to equipment noise reduction drop sound field more particularly to a kind of array type silencers.
Background technology
Silencer is one of the effective measures for controlling air power noise.Air power noise is a kind of common makes an uproar
Sound pollution source, from jet plane, rocket, spaceship, until pneumatic tool, air conditioner equipment, internal combustion engine, pressure
The intake and exhaust of container, pipeline valve etc. can all generate the very high air power noise of sound level.In these air powered equipments
Install silencer on gas channel or in intake and exhaust additional, so that it may to reduce its noise pollution.Silencer is a kind of technical ability permission air-flow
It passes through, and can effectively stop or weaken the device that acoustic energy is propagated outward.It is worth noting that silencer can only be used for dropping
The porting noise of low air powered equipment or the noise along pipe transmmision, and cannot reduce air powered equipment casing,
The noise of the radiation such as tube wall, motor.Not every noise source, which loads onto silencer, can reduce its noise, and silencer is face sky
Aerodynamic force noise and design.
However traditional slice structure silencer is higher for civil engineering installation requirement, underaction adjustment；And production technology
It is more complex；Effect of low-frequency sound absorption is poor.
Invention content
The utility model aim is to provide a kind of array type silencer, and multiple silencing pot array settings are simple for process, eliminate the noise
It is with obvious effects, solve the above technical problem.
In order to achieve the above technical purposes, reach above-mentioned technology requirement, technical solution is used by the utility model：
A kind of array type silencer, the array type silencer is arranged inside flange, including mounting bracket, the mounting bracket
On be provided with several silencing pots, the both ends of the silencing pot are both provided with kuppe, and there are two kuppe settings
Riveting nut；The silencing pot is fastened on by riveting nut in mounting bracket, and arrangement is in a triangle；The silencing pot packet
Lateral keel is included, longitudinal keel is provided with perforated plate in lateral keel and longitudinal keel surface, is provided with and disappears on the inside of perforated plate
Sound cotton, the noise elimination cotton are centrifugally glass-wool.
Preferably：The silencing pot is provided in round or rectangle.
Preferably：The kuppe is provided in round or rectangle.
Preferably：The flange is made of welded connection by channel steel.
Preferably：The mounting bracket uses C-type steel, is set as being transversely mounted holder and longitudinally mounted holder, described
The both ends of mounting bracket connect with flange vertical welding.
The beneficial effects of the utility model；A kind of array type silencer, compared with traditional structure：It is provided in mounting bracket
Several silencing pots, array discharge, there are two riveting nuts for kuppe setting；Its sound absorber width increases, the contact surface with air-flow
Product increases, and not only increases low frequency absorption coefficient, and processing technology is simple, assembly line form can be formed, using riveting nut
Form keeps making simpler, and installation is more convenient, time saving and energy saving；Silencing pot bottom is provided with universal wheel, composition activity maintenance door, side
Just it overhauls.

Specific implementation mode
In order to make the goal of the invention, technical solution and its advantageous effects of the utility model be more clear, below in conjunction with
The drawings and specific embodiments, the present invention will be further described in detail；
In the accompanying drawings：A kind of array type silencer, the array type silencer are arranged inside flange 6, including installation
Holder 7 is provided with several silencing pots in the mounting bracket 7, and the both ends of the silencing pot are both provided with kuppe 1,
There are two riveting nuts for the setting of kuppe 1；The silencing pot is fastened on by riveting nut in mounting bracket, arrangement
In a triangle；The silencing pot includes lateral keel 4, and longitudinal keel 5 is provided in lateral keel 4 and 5 surface of longitudinal keel
Perforated plate 3 is provided with noise elimination cotton 2 in 3 inside of perforated plate, and the noise elimination cotton 2 is centrifugally glass-wool.
The silencing pot is provided in round or rectangle；The kuppe is provided in round or rectangle；The flange 6
It is made of welded connection by channel steel；The mounting bracket 7 uses C-type steel, is set as being transversely mounted holder and longitudinally mounted branch
The both ends of frame, the mounting bracket 7 are connect with 6 vertical welding of flange.
The specific implementation of the utility model：The material of perforated plate is not limited only to select galvanized steel plain sheet, can flexibly select；
When kuppe is arranged to circle, using gentle arc-shaped, when kuppe is set as rectangle, use is trapezoidal, can more make gas in this way
Levelling is slow to be passed through；Keel bracket uses the direct one-pass molding of molding machine；In silencing pot bottom, installation steering wheel group is examined at activity
Door is repaiied, it is convenient to overhaul；Round silencing pot can be assembled into rocket cartridge type silencer, and rectangular guiding cover can be assembled into wedge square formation formula and disappears
Sound device；The silencing pot of the utility model compared with prior art, increases the width of sound absorber, increases with the contact area of air-flow
Greatly, low frequency absorption coefficient is improved, corresponding low frequency noise elimination effect also improves；With the increase of total absorption area, silencer
Whole sound deadening capacity is greatly improved；Metal shell can also be added in the outside of silencing pot, just be assembled into metal shell
Array type silencer.
Above-described embodiment is only intended to clearly illustrate made by the utility model and describes, and not to the limit of embodiment
It is fixed, to those of ordinary skill in the art, other various forms of variations can also be made on the basis of the above description
Or change, there is no necessity and possibility to exhaust all the enbodiments, and the obvious variation thus amplified out
Or among changing still in the scope of protection of the utility model.
