Abstract
The utility model relates to an air pipe noise elimination equipment, it includes a plurality of anechoic sheets and tie -beam, the firmware the dismantled fixed mounting that the anechoic sheet was equipped with through both ends is on the tie -beam, each side of anechoic sheet all is equipped with the V type groove of indent along airflow direction, the anechoic sheet is evenly arranged in air pipe along airflow direction, the both ends of anechoic sheet still are equipped with the kuppe that matches rather than the cross sectional shape respectively, and the anechoic sheet of neighbouring air pipe inner wall and the distance of air pipe inner wall are anechoic sheet interval within a definite time half, the utility model discloses compressive strength is high, and the installation flexibility is high and absorb sound effectually.
Description
Technical field
This utility model is related to a kind of ventilation shaft silencing equipment.
Background technology
Acoustic filter is for reducing the transfer voice via pipeline, conduit or opening, and does not stop setting of medium transmission
Standby.There is problems with traditional strip-type silencer：Traditional strip-type silencer generally existing structure is insecure, bearing in higher
Produce during external differential and subside；Traditional strip-type silencer all holds out against ventilation shaft opposed inner walls and installs, and must first survey in a pre-installation
The distance of amount ventilation shaft opposed inner walls, leads to anechoic sheet Installation Flexibility not enough, makes the installation of acoustic filter, maintenance less square
Just；Install because traditional strip-type silencer holds out against ventilation shaft opposed inner walls, anechoic sheet only has two sides and air flow contacts,
Less with air flow contacts area, thus causing actual soundproof effect less desirable.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of comprcssive strength high, peace
Dress motility height and the good acoustic filter for ventilation shaft of acoustically effective.
For solving above-mentioned technical problem, a kind of acoustic filter for ventilation shaft of the present utility model, including some noise eliminations
Piece and tie-beam, described anechoic sheet is fixedly mounted on tie-beam by the detachable firmware that two ends are provided with, described anechoic sheet
Each side is equipped with the V-groove of indent along airflow direction, and described anechoic sheet is evenly arranged in ventilation shaft along airflow direction.
Further, the two ends of described anechoic sheet further respectively have the kuppe mating with its cross sectional shape.
Yet further, between the distance of the anechoic sheet of neighbouring ventilation shaft inwall and ventilation shaft inwall is between anechoic sheet
Away from half.
Anechoic sheet is uniformly dispersed ground by using tie-beam by a kind of acoustic filter for ventilation shaft of the present utility model
In arrangement ventilation shaft, the layout of anechoic sheet can be changed according to demand, improve Installation Flexibility, make installation, maintenance more convenient, with
When improve the contact area of anechoic sheet and air-flow, improve soundproof effect；Acoustic filter arranges V also by each side of anechoic sheet
Type groove, improves the comprcssive strength of anechoic sheet, it is to avoid easily produce situation about subsiding when bearing higher inside and outside differential pressure.
Brief description
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is the structural representation of anechoic sheet of the present utility model.
Specific embodiment
Accompanying drawings below combines and this utility model is described in detail.
As depicted in figs. 1 and 2, a kind of acoustic filter for ventilation shaft, including some anechoic sheets 1 and tie-beam 2, in figure
6 pieces of anechoic sheets are only shown, it is not limited to 6 pieces, the quantity of anechoic sheet can change according to different demands.For reducing anechoic sheet
Resistance to air-flow, described anechoic sheet 1 be respectively arranged at two ends with the kuppe 1.2 mating with its cross sectional shape.Disappear to improve
The Installation Flexibility of sound piece, makes installation, safeguards more convenient, the fixing peace of detachable firmware that described anechoic sheet 1 is provided with by two ends
It is contained on tie-beam 2.In order to improve the comprcssive strength of anechoic sheet, in each side of described anechoic sheet 1 is equipped with along airflow direction
Recessed V-groove 1.1.In order to improve the contact area of anechoic sheet and air-flow, improve soundproof effect, described anechoic sheet 1 is along air-flow
Direction is evenly arranged in ventilation shaft 3.The anechoic sheet 1 of neighbouring ventilation shaft 3 inwall is to disappear with the distance of ventilation shaft 3 inwall
The half of the spacing between sound piece 1.
The above is preferred implementation of the present utility model, comes for those skilled in the art
Say, on the premise of without departing from this utility model principle, some improvement can also be made, it is new that these improvement are also regarded as this practicality
The protection domain of type.
