Description

Compressed air silencer

Technical Field

The utility model relates to the technical field of silencing equipment, in particular to a compressed air silencer.

Background

The silencer is a noise reduction device for an airflow pipeline with noise transmission, such as a pipeline and an elbow with sound absorption linings or a pipeline with suddenly changed interface agents and other discontinuous acoustic impedances, and can be used for attenuating or reflecting the pipeline noise. The former is called resistive muffler and the latter reactive muffler.

The silencer is an important part in all air compressors, the part is a part for eliminating sound when being understood from the name, the silencer plays a role in reducing air noise of the air compressors to a great extent, the existing compressed air silencer is used for directly enabling noise to enter a silencing pipe to be subjected to primary silencing treatment, the treatment effect is poor, and the treated noise cannot meet the noise reduction standard.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problems mentioned in the background art, the utility model provides a compressed air silencer, which adopts the following technical scheme:

the utility model provides a compressed air silencer, includes import short circuit, pipeline and export short circuit, its characterized in that: the left part of the inlet short joint is provided with a pipeline, compressed air and noise in the compressed air enter a primary silencing pipe through the inlet short joint to carry out primary treatment on high-frequency noise in the noise, the pipeline is internally provided with the primary silencing pipe, the primary silencing pipe is provided with silencing holes, part of the high-frequency noise and the inner wall of the primary silencing pipe are rubbed to convert sound into heat energy, low-frequency noise and part of the high-frequency noise come out through the silencing holes, the right part of the primary silencing pipe is communicated with the left part of the inlet short joint, the low-frequency noise and part of the high-frequency noise enter the sound-absorbing filler through the sound-absorbing holes on the silencing pipe to carry out secondary silencing, the sound-absorbing holes enter the inner wall of the pipeline and are provided with a group of shells, the shell is internally provided with the silencing holes, the sound-absorbing filler is arranged between the shell and the silencing holes, the sound-absorbing holes are arranged on the silencing holes, the left part of the pipeline is provided with the outlet short joint, compressed air exits the end interface.

Preferably: the left end and the right end of the pipeline are elliptical seal heads, so that the impact force of compressed air coming out of the pipeline is relieved, and noise can be more fully silenced.

Preferably: the surface of the shell is of a rough structure, and noise carried by part of compressed air is rubbed with the surface of the shell, so that part of noise is eliminated and heat energy is converted.

Preferably: the inlet short circuit is provided with a first flange, and the outlet short circuit is provided with a second flange, so that the inlet short circuit can be conveniently connected with other pipelines.

Preferably: the sound absorption filler is superfine glass rock wool which has a flame retardant function.

Preferably: the silencing hole pipe is made of galvanized material, and is effectively prevented from rusting.

The utility model has the following advantages: the utility model discloses a silencer, which is characterized in that a first-stage silencing pipe is arranged in a pipeline, compressed air and noise generated by the compressed air are rubbed and converted into heat energy between the first-stage silencing pipe and the inner wall of the first-stage silencing pipe, part of high-frequency noise in the noise is eliminated, first-stage dehumidification is realized, the rest compressed air, low-frequency noise and part of high-frequency noise enter the pipeline through sound holes, and the low-frequency noise and part of the high-frequency noise enter sound absorption materials through the sound absorption holes to realize second-stage silencing.
