FIG. 2 is a general schematic of the present application;

the reference numbers are as follows: the muffler comprises a muffler body 1, a cavity 11, an exhaust pipe 21, an inlet pipe 22, a sub-muffler mechanism 3, an expansion chamber 31, a filter screen 32, a main muffler mechanism 4, a muffler pipe 41, a muffler material 42 and a drain valve 5.

Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

As shown in fig. 1 and 2, an environment-friendly airflow silencer comprises a silencer main body 1, wherein the silencer main body 1 comprises a housing, a cavity 11 is arranged in the housing, two sections of air pipes are respectively arranged at two ends of the housing, one end of the air pipe used for being connected with a high-pressure exhaust mechanism is used as an air inlet pipe 22, and the other end of the air pipe is used as an exhaust pipe 21.

Wherein, it is above-mentioned still be provided with vice amortization mechanism 3 in the cavity 11, vice amortization mechanism 3 is including expansion chamber 31, expansion chamber 31 diameter is greater than intake pipe 22, expansion chamber 31 with intake pipe 22 intercommunication, it is specific, expansion chamber 31 is separated by the baffle that sets up two parallels in cavity 11 and forms, and intake pipe 22 one end is located the casing outside and is used for connecting high-pressure exhaust mechanism, and its other end inserts to expansion chamber 31 in.

In addition, a main silencing mechanism 4 is disposed on one side of the auxiliary silencing mechanism 3 away from the air inlet pipe 22, the main silencing mechanism 4 is also fixedly mounted in the cavity 11, a silencing packing cavity is disposed in the main silencing mechanism 4, a plurality of silencing pipes 41 penetrating through the silencing packing cavity are disposed in the silencing packing cavity, a plurality of silencing holes are disposed at positions of the silencing pipes 41 in the silencing packing cavity, silencing materials 42 are filled in the silencing packing cavity, one end of each silencing pipe 41 is communicated with the upper end of the expansion cavity 31, and the other end is communicated with the exhaust pipe 21, in one embodiment, the silencing packing cavity is disposed near the upper end of the expansion cavity 31, the lower end of the silencing packing cavity seals the expansion cavity 31, the silencing pipes 41 are straight pipes disposed in the silencing packing cavity, and it should be understood that the silencing pipes 41 can be directly communicated with the exhaust pipe, the exhaust pipe 21 may communicate with the cavity 11 through the housing indirectly.

The working principle of this application is, when high pressure exhaust mechanism exhausts, gas process intake pipe 22, gas at first enters into expansion chamber 31, because the diameter in expansion chamber 31 is great, the gas expansion velocity of flow slows down, thereby can reduce some air current sound, entering into the amortization passageway, inhale the sound through bloop and amortization material 42 on the amortization pipeline 41, the mesh of amortization has been reached, wherein, gas is when passing through expansion chamber 31, because the condensation easily takes place for the gas expansion, and because the upper end intercommunication in amortization pipeline 41 and expansion chamber 31, the drop of water after the condensation can be held back in expansion chamber 31, consequently, most comdenstion water can not get into to the amortization pipeline 41 along with gas in, consequently can not wet amortization material 42, it is preferred, amortization material 42 is the amortization sponge.

On the basis of the above, in order to further improve the sound attenuation effect, the parts of the inlet pipe 22 and the outlet pipe 21 in the cavity 11 are provided with a plurality of small holes.

In addition, in order to improve the interception effect of the condensed water, the auxiliary noise reduction mechanism 3 further includes a plurality of filter screens 32 disposed in the expansion chamber 31, and the condensed water is partially intercepted on the filter screens after the filter screens contact.

In addition, this application is still in expansion chamber 31 bottom is provided with and is used for opening and shutting expansion chamber 31's drain valve 5 can clear up the liquid of intercepting in the drain chamber through drain valve 5.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
