Description

Technical Field

[0001] The utility model relates to the technical field of double-channel venting and silencer, in particular to a double-channel venting and silencer device. Background Art

[0002] A muffler is a noise reduction device for air flow ducts that also transmit noise. It can be made of pipes and elbows with sound-absorbing linings, or by utilizing pipes with sudden changes in cross-sectional area and other discontinuous acoustic impedance.

[0003] In publication number: CN201320193621.7, a dual-path venting silencer is disclosed, in which the gas is discharged into a buffer tank without resistance, so that the original exhaust pressure can be reduced to below 50%. The depressurized gas is then divided into two paths for dual-path release. During the dual-path release process, the gas passes through a sound-absorbing board equipped with sound-absorbing material and is discharged on the circumferential side of the sound absorber, so that the noise can be greatly reduced.

[0004] However, the device lacks protection for the inside of the pipeline. When the airflow flows in the pipeline, it will cause noise in the pipeline. If the noise generated by the airflow impacting the pipeline is not handled, it will not only damage the internal structure of the pipeline and reduce the service life of the pipeline, but the noise will also pass through the pipeline to the outside of the pipeline, causing trouble to the surrounding residents and workers.

[0005] To this end, we propose a dual-path venting silencer. Utility Model Content

[0006] The main purpose of the utility model is to provide a dual-path venting silencer, which can prevent noise from being transmitted from the inside of the pipeline to the outside of the pipeline by setting a vacuum layer between the inner wall and the outer wall of the discharge buffer tank and the unobstructed release tank, and can reduce the impact force of the gas in the pipeline and the noise generated by the collision between the gas and the pipeline when combined with a wave protection pad, thereby effectively solving the problems in the background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A dual-path venting silencer device comprises a discharge buffer tank and an unobstructed release tank, both ends of the discharge buffer tank are provided with unobstructed release tanks, the unobstructed release tanks are provided at two locations, a first cavity is provided inside the discharge buffer tank, and second cavities are provided inside the two unobstructed release tanks, and the interior of the first cavity is connected to the interior of the second cavity;

[0009] An exhaust interface is provided on one side of the discharge buffer tank, a first buffer pad is provided inside the discharge buffer tank, and second buffer pads are provided on the inner bottoms of the two unobstructed release tanks.

[0010] Furthermore, the top of the unobstructed release tank is fixedly connected to the muffler through a flange interface, and the muffler is provided with two locations, and a third cavity is provided inside the two mufflers, and the interior of the third cavity is connected to the interior of the second cavity.

[0011] Furthermore, a second vacuum layer is provided between the inner wall and the outer wall of the muffler, a first sound-absorbing sponge is pasted on the inner wall of the muffler, and a second sound-absorbing sponge is pasted on the inner wall of the first sound-absorbing sponge.

[0012] Furthermore, an exhaust hole is provided at the top of the muffler, and a plurality of exhaust holes are provided. A noise meter is provided at the outside of the muffler, and a detection end of the noise meter is located inside the muffler.

[0013] Furthermore, wave protection pads are pasted on the inner walls of the discharge buffer tank and the unobstructed release tank, and a first vacuum layer is provided between the inner wall and the outer wall of the discharge buffer tank and between the inner wall and the outer wall of the two unobstructed release tanks.

[0014] Compared with the prior art, the utility model has the following beneficial effects: by setting a vacuum layer between the inner wall and the outer wall of the discharge buffer tank and the unobstructed release tank, the noise can be prevented from being transmitted from the inside of the pipeline to the outside of the pipeline, and in combination with a wave protection pad, the impact force of the gas in the pipeline can be reduced, and the noise generated by the collision between the gas and the pipeline can also be reduced.
