Abstract
The utility model discloses a kind of exhaust outlet denoising structures, including exhaust duct, described exhaust duct one end is installed with mounting plate, the mounting plate quadrangle is provided with installation bolt, another terminal bolt of exhaust duct installs connecting tube, the connecting tube lower end is provided with gas outlet, wind deflector is fixedly connected with inside the gas outlet, and wind deflector is equipped with three groups.The utility model by exhaust duct due to being designed to warp architecture, changeable air flow direction, pipeline air feed is after the decompression reduction of speed of exhaust duct, what can more be mitigated is discharged from gas outlet, larger noise is not will produce, since three-chip type semi-circular design is made in gas outlet, the separable segmentation sound of wind deflector, exhaust sound is allowed to greatly reduce, so as to effectively reduce noise when exhaust outlet air draft, pass through the sound-proof material of installation, also the propagation of sound can be obstructed, it more ensure that the effect of noise reduction, it is simple in structure, noise reduction effect is apparent, and low manufacture cost, it is suitble to produce in enormous quantities and uses.
Description
Technical field
The utility model is related to a kind of exhaust outlet, more particularly to a kind of exhaust outlet denoising structure.
Background technology
Exhaust system refers to prevent the nuisance that equipment generates in process of production from generating pollution to workshop air, often leads to
It crosses hood or inlet scoop is on the spot trapped nuisance, and be piped to cleaning equipment and handled, reach discharge
After standard, then reuse or it is discharged into air, is generally required for using exhaust outlet in exhaust system air draft is carried out to it.
But the exhaust outlet functionality of majority is all relatively simple currently on the market, it is also very inconvenient to use, traditional
Exhaust outlet majority is directly to go out formula exhaust outlet, and noise is very big, and highest estimated has 70-80 decibels, in line that factory outside noise can be caused exceeded,
Noise pollution causes environmental issue, is not suitable for producing use in enormous quantities.For this purpose, it is proposed that a kind of exhaust outlet denoising structure.
Utility model content
The main purpose of the utility model is to provide a kind of exhaust outlet denoising structure, the utility model is due to by exhaust duct
Be designed to warp architecture, air flow direction can be changed, pipeline air feed after the decompression reduction of speed of exhaust duct, can more mitigate from going out
Gas port is discharged, and not will produce larger noise, since three-chip type semi-circular design is made in gas outlet, when air is discharged from gas outlet
When, the separable segmentation sound of wind deflector is allowed to exhaust sound and greatly reduces, making an uproar when so as to effectively reduce exhaust outlet air draft
Sound can also obstruct the propagation of sound by the sound-proof material of installation, more ensure that the effect of noise reduction, simple in structure, noise reduction effect
Obviously, and low manufacture cost, suitable mass production use, and can effectively solve the problems in background technology.
To achieve the above object, the technical solution that the utility model is taken is：
Mounting plate, the mounting plate is fixedly mounted in a kind of exhaust outlet denoising structure, including exhaust duct, described exhaust duct one end
Quadrangle is provided with installation bolt, and another terminal bolt of exhaust duct installs connecting tube, and the connecting tube lower end is provided with gas outlet,
Wind deflector is fixedly connected with inside the gas outlet, and wind deflector is equipped with three groups.
Further, it is provided with sound-proof material between the gas outlet inner wall and outer wall.
Further, the exhaust duct is the exhaust duct of warp architecture.
Further, the wind deflector is the wind deflector of semicircular structure.
Further, the gas outlet can make three-chip type semi-circular design by wind deflector.
Compared with prior art, the utility model has the advantages that：
1, since exhaust duct is designed to warp architecture air flow direction can be changed, pipeline air feed is by row in the utility model
After the decompression reduction of speed of air hose, what can more be mitigated is discharged from gas outlet, not will produce larger noise.
2, the utility model, when air is discharged from gas outlet, is led since three-chip type semi-circular design is made in gas outlet
The separable segmentation sound of aerofoil, is allowed to exhaust sound and greatly reduces, so as to effectively reduce noise when exhaust outlet air draft.
3, the utility model can also obstruct the propagation of sound, more ensure that the effect of noise reduction by the sound-proof material of installation,
Simple in structure, noise reduction effect is apparent, and low manufacture cost, is suitble to produce use in enormous quantities.

Specific implementation mode
To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below
In conjunction with specific implementation mode, the utility model is expanded on further.
As shown in Figs. 1-3, peace is fixedly mounted in a kind of exhaust outlet denoising structure, including exhaust duct 1,1 one end of the exhaust duct
Loading board 6,6 four jiaos of the mounting plate are provided with installation bolt 5, and 1 another terminal bolt of the exhaust duct installs connecting tube 2, the company
2 lower end of take over is provided with gas outlet 3, wind deflector 4 is fixedly connected with inside the gas outlet 3, and wind deflector 4 is equipped with three groups.
Wherein, it is provided with sound-proof material 7 between 3 inner wall of the gas outlet and outer wall.
Wherein, the exhaust duct 1 is the exhaust duct of warp architecture.
Wherein, the wind deflector 4 is the wind deflector of semicircular structure.
Wherein, the gas outlet 3 can make three-chip type semi-circular design by wind deflector 4.
It should be noted that the utility model is a kind of exhaust outlet denoising structure, when work, first passing through mounting plate 6 will arrange
Air port is installed, in use, air can enter in exhaust duct 1, air flow direction can be changed in exhaust duct 1, and pipeline air feed is by row
After the decompression reduction of speed of air hose 1, what can more be mitigated is discharged from gas outlet 3, larger noise is not will produce, due to doing gas outlet 3
At three-chip type semi-circular design, when air is discharged from gas outlet 3, it is big to be allowed to exhaust sound for the separable segmentation sound of wind deflector 4
Big to reduce, so as to effectively reduce noise when exhaust outlet air draft, and sound-proof material 7 can also obstruct the propagation of sound, more protect
The effect of noise reduction is demonstrate,proved.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
