Description
Technical field
Boiler chimney technical field is the utility model is related to, is specially a kind of muffler anechoic sheet.
Background technology
Boiler is the indispensable heat power equipment of thermal power industry, and boiler operatiopn noise is universal existing for each city
Disturb residents sound source.The noise pollution of boiler chimney is the main noise pollution of boiler operatiopn.Since gas turbine (air-introduced machine) conveys
The high temperature gas flow come transmits the air pertormance noise that wind turbine produces along pipeline, because steel pipe is to noise alleviation very little,
Environmental noise is often resulted in from the noise of throat effusion and exceedes local criteria for noise, and becoming influences workers ' health and interference environment
Misfortune source.Particularly adjacent to the chimney in living area, its air pertormance noise produced, even more pollutes the principal element of environment,
Public hazards are formed, are one of the main objects that Industry Branch administers noise pollution in recent years.Usually installed in boiler chimney
Muffler carries out the elimination to noise, and existing muffler noise elimination chip architecture is single, and erasure effect is poor, and service life is low, is
This, it is proposed that a kind of muffler anechoic sheet.
Utility model content
It is proposed in the above background technology existing to solve the purpose of this utility model is to provide a kind of muffler anechoic sheet
The problem of some muffler noise elimination chip architectures are single, and erasure effect is poor, and service life is low.
To achieve the above object, the utility model provides following technical solution：A kind of muffler anechoic sheet, including by two groups
The anechoic sheet skeleton of bottom bound edge and two groups of side bound edge compositions, the bottom of the anechoic sheet skeleton is provided with kuppe, the noise elimination
Be both provided with lifting lug at left and right sides of the top of piece skeleton, the inner cavity of the anechoic sheet skeleton be longitudinally equidistantly positioned two groups erect every
Bar, the inner cavity of the anechoic sheet skeleton have laterally been equidistantly positioned two groups of tabula bars, the inner cavity of the anechoic sheet skeleton or so two
Punched-plate is both provided with, ceramic blanket and steel wire are provided between punched-plate described in two groups, and steel wire is wrapped in ceramic blanket
Outer wall.
Preferably, the left and right sides of the top and bottom of the tabula bar is tiltedly installed with reinforcing plate.
Preferably, the bottom of the kuppe is provided with semi-circular sheet steel.
Compared with prior art, the beneficial effects of the utility model are：A kind of muffler that the utility model proposes is eliminated the noise
Piece, simple in structure, structural strength is high, significantly reduces the weight of muffler, convenient to install and maintain, and sound-absorbing effect is good, cost
It is cheap, service life length.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
In figure：1 anechoic sheet skeleton, 2 kuppes, 3 punched-plates, 4 side bound edges, 5 bottom bound edges, 6 ceramic blankets, 7 steel wires, 8 are hung
Ear, 9 tabula bars, 10 perpendicular spacer bars.
Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained, shall fall within the protection scope of the present invention.
Referring to Fig. 1, the utility model provides a kind of technical solution：A kind of muffler anechoic sheet, including wrapped by two groups of bottoms
The anechoic sheet skeleton 1 that side 5 and two groups of side bound edges 4 form, the bottom of the anechoic sheet skeleton 1 is provided with kuppe 2, the noise elimination
Lifting lug 8 is both provided with left and right sides of the top of piece skeleton 1, the inner cavity of the anechoic sheet skeleton 1 has longitudinally been equidistantly positioned two groups
Perpendicular spacer bar 10, the inner cavity of the anechoic sheet skeleton 1 have laterally been equidistantly positioned two groups of tabula bars 9, the anechoic sheet skeleton 1 it is interior
Chamber or so two is both provided with punched-plate 3, ceramic blanket 6 and steel wire 7 is provided between punched-plate 3 described in two groups, and steel wire 7 wraps
It is rolled in the outer wall of ceramic blanket 6.
Wherein, the left and right sides of the top and bottom of the tabula bar 9 is tiltedly installed with reinforcing plate, the kuppe 2
Bottom be provided with semi-circular sheet steel.
Operation principle：The anechoic sheet skeleton 1 formed using two groups of bottom bound edges 5 and two groups of side bound edges 4, bottom bound edge 5 and side bag
Side 4 uses stainless steel, and is welded to each other, and improves the stability and intensity of structure, top of anechoic sheet skeleton 1 or so two
Side is both provided with lifting lug 8, is easily installed and moves, and sound deadening is realized using punched-plate 3 and ceramic blanket 6, tabula bar 9 and it is perpendicular every
Bar 10 plays the role of structural strengthening, the utility model of simple structure and strong practicability.
While there has been shown and described that the embodiment of the utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from the principle of the utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
