Abstract
The utility model discloses a matrix-type ventilation silencer which comprises a frame body and a plurality of silencing pillars, wherein the silencing pillars are uniformly distributed in the frame body and parallel to one another; all the silencing pillars are arranged in a matrix manner; and the different silencing pillars as well as the silencing pillars and the frame body are connected through connecting rods. The matrix-type ventilation silencer adopts the matrix-type silencing pillars, the sizes of the silencing pillars are changeable, and the distance between the every two adjacent silencing pillars is changeable, so that the salience requirements of noises with different characteristics can be met, the slicing quantity is large, the licensing frequency is wide, and the reutilization rate of the licensing pillars is high; and the licensing pillars are connected through the connecting rods, so that the mounting is convenient and fast; and the silencer has a simple structure, and is easy to process, and wide in application range.
Description
Technical field
The utility model relates to a kind of ventilation silencer that is used for environment-friendly engineering, relates in particular to a kind of matrix form ventilation silencer.
Background technology
When rapid economy development was brought the living standard that improves day by day to people, problem of environmental pollution was also serious day by day.Noise pollution more and more becomes the problem that people pay close attention to, and ventilation silencer is the effective tool that reducing noise pollutes.
The ventilation silencer that is used for environment-friendly engineering at present adopts cylindric or laminated structure, or installs complicatedly, and it is not convenient to construct, or simple in structure but noise elimination weak effect, but and all has a low shortcoming of recycling rate of waterused.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, effective matrix form ventilation silencer of eliminating the noise with regard to being in order to address the above problem.
The utility model is realized above-mentioned purpose through following technical scheme:
The utility model comprises framework and noise elimination post; Said noise elimination post is a plurality of; Be uniformly distributed in the said framework and be parallel to each other, all said noise elimination posts are arranged, between the different said noise elimination posts, all be connected through connecting rod between said noise elimination post and the said framework.
Particularly; Said noise elimination post comprises the air diffuser of air intake, the metal tube in stage casing and the plug of outlet air end; Said air diffuser be outer little in big conically shaped body; The cross section of said metal tube is a rectangle, evenly is provided with the aperture that is interlinked to the outside in a plurality of on the tube wall of said metal tube, is filled with sound-absorbing material in the said metal tube.Behind the circular cone arcwall face of air-flow contact air diffuser, spread, pass through, reduced the pressure resistance of noise elimination post effectively air from the space between noise elimination post and the noise elimination post; When air passed the noise elimination post, the sound-absorbing material in the metal tube can sqouynd absorption lowering noise, reduces noise.
As preferably, the surface area of all said apertures account for said metal tube surface area 20%.
For easy for installation, quick, said noise elimination post is connected with said connecting rod through bolt.
The beneficial effect of the utility model is:
The utility model adopts array noise elimination post, noise elimination post variable size, and gap variable between the noise elimination post, thus satisfying the noise noise elimination requirement of different qualities, sound deadening capacity is big, and frequency of noise elimination is wide, and the recycling rate of waterused of noise elimination post is high; Connect the noise elimination post through connecting rod, quick and easy for installation; The utility model is simple in structure, is easy to processing, is widely used.
Description of drawings
Fig. 1 is the front view of the utility model;
Fig. 2 is the left view after the utility model removes the left side framework;
Fig. 3 is the structural representation of the said noise elimination post of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Shown in Fig. 1 and Fig. 2; The utility model comprises framework 2 and noise elimination post 1; Noise elimination post 1 is a plurality of; Be uniformly distributed in the framework 2 and be parallel to each other, all noise elimination posts 1 are arranged, between the different noise elimination posts 1, all be connected through bolt (unmarked among the figure) through connecting rod 3 between noise elimination post 1 and the framework 2.
As shown in figures 1 and 3; Noise elimination post 1 comprises the air diffuser 4 of air intake, the metal tube 6 in stage casing and the plug 7 of outlet air end, air diffuser 4 be outer little in big conically shaped body, the cross section of metal tube 6 is a rectangle; Evenly be provided with the aperture (unmarked among the figure) that is interlinked to the outside in a plurality of on the tube wall of metal tube 6; The surface area of aperture account for metal tube 6 surface area 20%, be filled with sound-absorbing material 5 in the metal tube 6, sound-absorbing material 5 is conventional general material.The inner of plug 7 is installed in the metal tube 6.
Like Fig. 1, Fig. 2 and shown in Figure 3, behind the circular cone arcwall face of air-flow contact air diffuser 4, spread, pass through from the space between the adjacent noise elimination post 1, reduced the pressure resistance of 1 pair of air of noise elimination post effectively; When air passed noise elimination post 1, the sound-absorbing material 5 in the metal tube 6 can sqouynd absorption lowering noise, reduces noise.
Calculate the wavelength of the frequency band noise that is primarily aimed at according to aerial spread speed of noise and frequency meter; Confirm the size of noise elimination post 1, the spacing between the adjacent noise elimination post 1 according to wavelength characteristic, and then design and satisfy the different matrix form ventilation silencers of eliminating the noise and requiring.
