Description
Technical field
The utility model is related to noise reduction technical fields, are specially a kind of chimney muffler.
Background technology
The main function of chimney is the cigarette that puts a chimney on the stove and make the fire draw, and drains flue gas, improves burning condition, and current general chimney does not have noise reduction
Device, and noise pollution is excessive when discharging flue gas, for this purpose, we have proposed a kind of chimney mufflers.
Utility model content
It is mentioned above in the background art general to solve the purpose of this utility model is to provide a kind of chimney muffler
Chimney there is no silencing means, and the problem of noise pollution is excessive when discharging flue gas.
To achieve the above object, the utility model provides following technical solution：A kind of chimney muffler, including kuppe,
Bottom silencer is connected at the top of the kuppe, muffler, the bottom silencer are connected at the top of the bottom silencer
Ceramic fiber blanket is bonded with the inner wall of upper muffler, the inner wall of the ceramic fiber blanket is provided with hollow shelf, the sky
The inner wall of septum cordis plate is provided with heat insulation sound silencing board, the cross central line pair of the inner cavity of the heat insulation sound silencing board on heat insulation sound silencing board
Title is provided with two groups of punched-plates, and the inner cavity of the heat insulation sound silencing board of the upper suppressor lumen is longitudinally evenly arranged with acoustical cotton plate,
And acoustical cotton plate is set with punched-plate square crossing.
Preferably, flanged joint between the kuppe, bottom silencer and upper muffler.
Preferably, bonded together between the ceramic fiber blanket, hollow shelf and heat insulation sound silencing board by adhesive.
Preferably, the heat insulation sound silencing board is aluminosilicate heat insulation sound silencing board.
Compared with prior art, the beneficial effects of the utility model are：By the setting of this chimney muffler, it is mountable to
Chimney top carries out noise reduction to chimney, reduces noise pollution, improves working environment.
Description of the drawings
Fig. 1 is the utility model structure diagram.
In figure：1 kuppe, 2 bottom silencers, muffler, 4 ceramic fiber blankets, 5 hollow shelfs, 6 heat insulation sound silencing boards, 7 on 3
Punched-plate, 8 acoustical cotton plates.
Specific 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
It clearly and completely describes, 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 chimney muffler, it is described including kuppe 1
The top of kuppe 1 is connected with bottom silencer 2, and the top of the bottom silencer 2 is connected with muffler 3, the bottom silencer 2
Ceramic fiber blanket 4 is bonded with the inner wall of upper muffler 3, the inner wall of the ceramic fiber blanket 4 is provided with hollow shelf 5, institute
The inner wall for stating hollow shelf 5 is provided with heat insulation sound silencing board 6, the transverse direction of the inner cavity of the heat insulation sound silencing board 6 on heat insulation sound silencing board 6
Center line symmetrical setting has two groups of punched-plates 7, and the inner cavity of the heat insulation sound silencing board 6 of upper 3 inner cavity of muffler is longitudinally uniformly arranged
There is acoustical cotton plate 8, and acoustical cotton plate 8 is set with 7 square crossing of punched-plate.
Wherein, flanged joint between the kuppe 1, bottom silencer 2 and upper muffler 3, easy to connect, the ceramics are fine
It is bonded together between dimension blanket 4, hollow shelf 5 and heat insulation sound silencing board 6 by adhesive, makes connection structure more stable, the guarantor
Warm acoustical panel 6 be aluminosilicate heat insulation sound silencing board, noise reduction good heat-insulation effect.
Operation principle：Kuppe 1 is connected with chimney top, ceramic fiber blanket 4 can play the role of heat-insulating, fire-preventing, empty
Septum cordis plate 5 can play the role of heat-insulating sound-insulating, and heat insulation sound silencing board 6 can play heat-resisting noise reduction, multiple heat-insulated noise reduction
Protection, make the heat insulation of this muffler and erasure effect more preferable, be not easy to feel when making staff close to this muffler
To hot gas and noise, comfortable environment is given people, when flue gas is discharged into bottom silencer 2 by kuppe 1, the flue gas of flowing is by small
The passage of cross section enters the passage of big cross section, and when being flowed into 2 inner cavity of bottom silencer, flue gas, which is spread apart, to be come, flowing velocity
It is slack-off, while by the stop and shunting of punched-plate 7, the flowing velocity for making flue gas is slower, reduces noise, and then flue gas passes through
Bottom silencer 2 is flowed into upper muffler 3, is further reduced noise, and is absorbed by acoustical cotton plate 8, makes flue gas during discharge
Speed is slow, and noise is lower, plays the role of noise reduction, good muffling effect.
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 in the case where not departing from the principle of the utility model and spirit can these embodiments be carried out with a variety of variations, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
