Abstract
The utility model relates to a kind of reactive mufflers, including cylindrical silencing pot, characterized by further comprising it is several along side wall ring around first baffle and it is several along silencing pot axle center arrangement second baffle, the first baffle and the second baffle are spaced, the second baffle is equipped with through-hole, the second baffle outer diameter is greater than the internal diameter of the first baffle, the second baffle connects the first baffle by connecting column, and the second baffle and the first baffle are equipped with honeycomb groove；Using the utility model sound in the process of propagation, first pass through first baffle, the abrupt change of cross-section reduces sound, second baffle can change the path of sound transmission, make sound can not directly straight line propagated in silencing pot, curve propagation can only be carried out, to make sound have the function that interfere, to play the effect of noise reduction.
Description
Technical field
The utility model relates to silencer fields, and in particular to a kind of reactive muffler.
Background technique
Reactive muffler is that production connects resonant cavity etc. during acoustic propagation by the mutation of pipeline section or side and causes
The change of impedance and generation sound can reflection, interference, so that the sound energy from silencer to external radiation is reduced, to reach noise elimination purpose
Silencer.A kind of silencer that sound wave is reflected back into sound source.Impedance is lost using structures such as expansion and acoustic resonator in it
It is equipped with reflected acoustic wave.It is mainly used for air compressor, automobile engine and other piston-engined air inlets and exhaust outlet, especially
The case where suitable for low-frequency noise elimination and having high temperature, inflammable gas.
The utility model designs a kind of structure of novel reactive muffler, and more abundant and comprehensive is utilized section
The effect that mutation and sound interfere, to achieve the effect that noise elimination.
Utility model content
In order to solve the above problem, the utility model is achieved through the following technical solutions:
A kind of reactive muffler, including cylindrical silencing pot and it is several along side wall ring around first baffle and several
Along the second baffle of silencing pot axle center arrangement, the first baffle and the second baffle are spaced, on the second baffle
Equipped with through-hole, the second baffle outer diameter is greater than the internal diameter of the first baffle, and the second baffle connects institute by connecting column
First baffle is stated, the second baffle and the first baffle are equipped with honeycomb groove.
The lead to the hole site of through-hole eccentric setting, two adjacent second baffles mutually staggers.
First baffle is in a circular table shape, and the first baffle gradually extends along the direction of voice transmission from inside to outside.
In coniform, the second baffle gradually extends along the direction of voice transmission second baffle from inside to outside.
The utility model has the advantages that
1, using the utility model sound in the process of propagation, first baffle is first passed through, the abrupt change of cross-section reduces sound,
Second baffle can change the path of sound transmission, make sound can not directly straight line propagated in silencing pot, curve can only be carried out
It propagates, to make sound have the function that interfere, to play the effect of noise reduction.
2, through-hole eccentric setting, and position mutually staggers, and sound can not be made from straightline propagation, sound can be made to distinguish
It is propagated from the position between through-hole and first baffle and second baffle, to be easier to play the role of interfering.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the utility model cross section structure schematic diagram.
Appended drawing reference is as follows:
1, silencing pot；2, first baffle；3, second baffle；31, through-hole；4, connecting column.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples, it should be understood that this is practical new
The structure of type is not limited in following embodiment:
As shown in Figs. 1-2, a kind of reactive muffler, including cylindrical silencing pot 1 and it is several along side wall ring around
First baffle 2 and several second baffles 3 along the arrangement of 1 axle center of silencing pot, the first baffle 2 are alternate with the second baffle 3
Arrangement, the second baffle 3 are equipped with through-hole 31, and 3 outer diameter of second baffle is greater than the internal diameter of the first baffle 2, described
Second baffle 3 connects the first baffle 2 by connecting column 4, and the second baffle 3 is equipped with honeycomb with the first baffle 2
Shape groove.
Using the utility model, sound passes through silencing pot 1, respectively between second baffle 3 and first baffle 2 and from logical
It is propagated in hole 31, can play the role of interfering, when sound passes through first baffle 2, generate the abrupt change of cross-section, it can
To lower sound, the comprehensive effect for playing noise reduction.
31 position of the through-hole of 31 eccentric setting of through-hole, the second baffle 3 of adjacent two mutually staggers.Through-hole 31
Position mutually stagger, can not make through-hole 31 white silk it is in alignment, make sound along straightline propagation.
First baffle 2 is in a circular table shape, and the first baffle 2 gradually extends along the direction of voice transmission from inside to outside.
In coniform, the second baffle 3 gradually extends along the direction of voice transmission second baffle 3 from inside to outside.Using
Above-mentioned scheme is easy the effect of the inclined surface by first baffle 2 and second baffle 3 in the communication process of sound, makes sound edge
Silencing pot 1 one both fixed track is transmitted so that sound is easier to play the role of interfering in transmission process, from
And achieve the effect that noise reduction.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Ability
The technology people in domain is described in the above embodiment and specification it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model can also
There are various changes and modifications, these various changes and improvements fall within the scope of the claimed invention.The utility model is wanted
Protection scope is asked to be defined by the appending claims and its equivalent thereof.
