Further, the expansion cavity and it is connected with and puts three groups of expansion chambers, sound deadening capacity, expansion chambers described in three groups can be effectively improved
Entrance is collected at one and passes through the first partition, and expansion chambers outlet described in three groups both passes through the second partition, and air-flow leads to
Noise can effectively be reduced by crossing the change in section.
Further, the expansion chambers are arranged in series three segment length gradually increased cavity.
Further, the sound-absorbing material both ends are bonded in the inner walls, and the sound-absorbing material surface is arranged to
Folded plate type, the contact area of increase noise and the sound-absorbing material, the sound-absorbing material surface cover wire netting as mask knot
Structure, can protect the sound-absorbing material.
Further, the lead to the hole site of the 3rd partition plate, the 4th partition plate and the 5th partition plate is different, this
Sample can change the direction of airflow, effectively reduce noise.
Further, described porous snorkel one end is fixedly connected on the 5th partition plate, and the porous snorkel is another
One end is fixedly connected on the gas outlet inner wall.
Further, the through-hole diameter of the porous ventilation tube wall is arranged to from the remote gas outlet to the outlet
Mouthful direction is gradually reduced, different through-hole diameters can specific aim eliminate the noise of different frequency.
Relative to the prior art, a kind of silencing means described in the invention has the advantage that：
(1) a kind of silencing means described in the invention effectively eliminates the noise of different frequency, highly practical.
(2) a kind of silencing means described in the invention is applied widely, and simple in structure, noise elimination effect is preferable.

Embodiment
It should be noted that in the case where there is no conflict, the feature in embodiment and embodiment in the invention can
To be mutually combined.
The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments creates.
A kind of silencing means, including cylindrical shell 1,1 both ends of housing are respectively equipped with air inlet 2 and gas outlet 3,
From described 2 one end of air inlet, order sets first partition 4, second partition 5, the 3rd partition plate 6,7 and of the 4th partition plate in the housing 1
5th partition plate 8, sets deflector 21, the first partition 4 and described second between the air inlet 2 and the first partition 4
Expansion cavity 9 is set between partition plate 5, setting sound-absorbing material 10 between the second partition 5 and the 3rd partition plate 6, the described 3rd
Through hole is equipped with partition plate 6, the 4th partition plate 7 and the 5th partition plate 8, is equipped between the 5th partition plate 8 and the gas outlet 3 porous
