Description
본 고안은 압축기용 소음기에 관한 것으로, 더욱 상세하게는 압축기로 흡입되는 공기가 에어필터를 통과하여 압축기의 실린더로 유입되는 과정의 공기흐름을 개선하여 소음을 작게하는 압축기용 소음기에 관한 것이다.The present invention relates to a silencer for a compressor, and more particularly to a silencer for the compressor to reduce the noise by improving the air flow in the process of the air sucked into the compressor through the air filter into the cylinder of the compressor.
종래에도 본 고안과 같은 목적으로 개발된 다양한 소음기들이 제안되어 있지만, 그 가운데 선출원된 실용신안등록 제225151호가 있다.Conventionally, various silencers developed for the same purpose as the present invention have been proposed, but among them, there is a utility model registration No. 225151 filed previously.

상기와 같이 구성되는 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.
첨부도면 도 4내지 도 5에서와 같이 압축기(미도시)와 연결된 배기구(12)로 공기가 배출되면 몸통(11)의 내부에 존재하는 공기가 압축기로 흡입된다.When the air is discharged to the exhaust port 12 connected to the compressor (not shown) as shown in FIGS. 4 to 5, air existing in the body 11 is sucked into the compressor.
상기와 같이 몸통(11)의 내부에 기압이 하강되면 외부의 공기가 필터부(20)의 흡기판(23)에 환상으로 설치된 다수의 가는흡기관(23a)들을 통하여 필터커버(22)로 감싸여 밀폐된 공간의 흡기공동실(22a)에 유입된다.When the air pressure is lowered inside the body 11 as described above, the outside air is wrapped in the filter cover 22 through a plurality of fine intake pipes 23a annularly installed on the intake plate 23 of the filter unit 20. The gas flows into the air intake cavity 22a of the sealed space.
상기와 같이 유입되는 공기는 다수의 가는흡기관(23a)으로 분산되어 유입됨으로서 가는흡기관(23a)을 통과하는 공기의 흐름속도는 낮은 상태를 유지한다.As the air introduced as described above is dispersed and introduced into the plurality of fine intake pipes 23a, the flow rate of air passing through the fine intake pipe 23a is maintained at a low state.
따라서, 흡기공동실(22a)에 유입될 때의 기류소음은 발생되지 않으며 에어필터(21)의 전둘레에 배열설치된 가는흡기관(23a)에 의하여 공기가 에어필터(21)의 주변에 고르게 분산됨으로 와류현상은 발생되지 않는다.Therefore, no airflow noise is generated when the air inlet cavity 22a flows into the air, and the air is evenly distributed around the air filter 21 by the thin air intake pipe 23a arranged around the air filter 21. Therefore, no vortex phenomenon occurs.
상기와 같이 흡기공동실(22a)에 고르게 흡입된 공기는 에어필터(21)를 통과하면서 와류현상을 발생하지 않게 되어 굵은흡기관(13)의 굵은관진입부(13a)로 가지런히 모아지게 된다. 이때, 분산되어 에어필터(21)를 통과한 공기가 정화되면서 한곳으로 모아 짐으로서 굵은흡기관(13)을 통과하는 공기의 흐름이 빠른 상태로 굵은관배출부(13b)를 통과하게 된다.As described above, the air evenly sucked into the intake cavity chamber 22a does not generate vortex while passing through the air filter 21, and is collected neatly into the coarse pipe inlet 13a of the thick intake pipe 13. . At this time, as the air passed through the air filter 21 is dispersed and collected in one place, the air flowing through the thick intake pipe 13 passes through the thick pipe discharge part 13b in a fast state.
상기와 같이 배출된 공기는 속도가 매우 빠름으로 공명상쇄판(31)의 확산면(31b)에 충돌하게 되면서 공기를 확산시켜 흐름속도를 감소시키게 되는데 이때 상기 확산면(31b)을 진동시키게 된다. 또한, 확산되는 공기는 몸통(11)의 내부 기압을 상승시키며 그 상승된 기압에 의하여 공명상쇄판(31)의 상측에 천공된 공명상쇄공(31a)을 통하여 공명상쇄케이스(33)의 공명실(33a)로 확산된다.As the air discharged as described above collides with the diffusion surface 31b of the resonance canceling plate 31, the air is diffused to decrease the flow rate by vibrating the diffusion surface 31b. In addition, the diffused air raises the internal air pressure of the body 11 and the resonance chamber of the resonance canceling case 33 through the resonance offset hole 31a drilled on the upper side of the resonance offset plate 31 by the elevated air pressure. It spreads to 33a.
상기와 같이 공명실(33a)로 확산되어진 공기는 확산면(31b)에 충돌하면서 발생한 확산면(31b)에 접촉됨으로 진동하려는 확산면(31b)을 안정시키게 된다. 상기와 같이 공명상쇄판(31b)에 의해 확산된 공기는 기류차단판(17)에 의하여 보다 흐름속도를 낮추면 안정되며, 그 안정된 공기는 다시 기류차단판(17) 외측의 공간으로 이동하여 몸통(11)의 내부로 유입되고, 배기구(12)를 통하여 압축기로 배출되는 것이다.The air diffused into the resonance chamber 33a as described above is in contact with the diffusion surface 31b generated while colliding with the diffusion surface 31b to stabilize the diffusion surface 31b to vibrate. As described above, the air diffused by the resonance canceling plate 31b is stabilized by lowering the flow rate by the air blocking plate 17, and the stabilized air is moved back to the space outside the air blocking plate 17, and the body ( 11) is introduced into the interior, and is discharged to the compressor through the exhaust port (12).
상술한 바와 같이 본 고안에 의한 압축기용 소음기에 의하면, 에어필터에 접촉되는 공기의 흐름이 와류현상을 발생하지 않아 안정된 상태에서 에어필터를 통과함으로 필터링효율이 상승됨과 동시에 기류소음이 발생하지 않게 됨은 물론, 상기 에어필터를 통과한 공기가 안정적으로 모아 짐으로서 기류소음은 발생되지 않으며, 기압이 낮은 몸통으로 유입될 때 발생되는 확산음은 공명상쇄케이스에 형성된 공명실과 공명상쇄판에 의하여 제거함으로서 대용량의 청정공기를 압축하여 사용하는 고압 대용량의 압축기에 매우 유용하게 적용할 수 있는 고안인 것이다.As described above, according to the compressor silencer according to the present invention, the flow of air in contact with the air filter does not generate a vortex phenomenon and passes through the air filter in a stable state, thereby increasing the filtering efficiency and not generating airflow noise. Of course, as the air passing through the air filter is collected stably, no airflow noise is generated, and the diffused sound generated when the air pressure flows into the lower body is removed by the resonance chamber and the resonance offset plate formed in the resonance canceling case. It is a design that can be very usefully applied to a high-pressure large-capacity compressor used for compressing clean air.
