본 발명은 압축기의 소음저감장치에 관한 것으로, 특히 압축기의 실린더 내에서 발생하는 소음이 외부로 누출되는 것을 최소화시키기 위한 소음저감장치에 관한 것이다.The present invention relates to a noise reduction device of a compressor, and more particularly, to a noise reduction device for minimizing leakage of noise generated in a cylinder of a compressor to the outside.

일반적으로 압축기는 기체를 압축시켜 그 압력을 높이는 장치로서, 압축공기를 일정한 용량의 저장탱크에 저장했다가 필요시 이 고압의 저장 공기를 이용하여 여러 가지의 작업을 가능하게 하는 장비이다.In general, a compressor is a device that compresses gas to increase pressure, and stores compressed air in a storage tank having a constant capacity, and when necessary, uses a high-pressure storage air to enable various operations.

이와 같은 압축기는 실린더블록 내측에 설치되어 있는 피스톤을 상하왕복 운동시킴으로써 흡기밸브를 통해 공기를 흡입하고 이를 압축하여 배기밸브를 통해 배기시킴에 따라 토출파이프를 통해 압축공기를 저장탱크에 저장시킨다.Such a compressor sucks air through the intake valve by reciprocating the piston installed inside the cylinder block, and compresses it and exhausts it through the exhaust valve, thereby storing the compressed air in the storage tank through the discharge pipe.

그런데, 상기 흡기밸브가 빠른속도로 왕복운동하면서 공기를 흡입하는 과정에서 흡기밸브가 밸브시트에 충돌하면서 소음이 발생하게 되는데, 이러한 소음을 줄이기 위해 종래에는 압축기의 흡입구 측에 에어필터를 내장한 소음저감장치를 설치하였다.However, in the process of sucking the air while the intake valve reciprocates at a high speed, noise is generated while the intake valve collides with the valve seat. In order to reduce such noise, conventionally, an air filter is built in the inlet of the compressor. An abatement device was installed.

이와 같이, 국내특허등록 제501567호에 게재된 종래의 소음저감장치는 에어필터를 감싸는 케이스가 주로 불투명한 금속재로 이루어져 있어, 케이스 내측의 에어필터의 오염정도를 확인할 수 없었으며 이를 확인하기 위해서는 상부 커버를 흡 기구 또는 케이스로부터 분리해야하는 번거로운 문제가 있었다.As described above, the conventional noise reduction device disclosed in Korean Patent Registration No. 501567 is mainly made of an opaque metal material surrounding the air filter, so that the degree of contamination of the air filter inside the case could not be confirmed. There has been a cumbersome problem of removing the cover from the intake or case.

상기한 문제를 해결하기 위해, 본 발명의 목적은 실린더 내로 유입되는 공기를 필터링하기 위한 에어필터의 오염정도를 소음저감장치 외부에서 육안으로 쉽게 확인하여 에어필터의 교체시기를 파악할 수 있는 소음저감장치를 제공하는데 있다.In order to solve the above problems, an object of the present invention is to reduce the pollution level of the air filter for filtering the air flowing into the cylinder with the naked eye from the outside of the noise reduction device to easily determine the replacement time of the air filter noise reduction device To provide.

본 발명의 다른 목적은 압축기의 흡기구에서 발생하는 소음이 외부로 누출되는 것을 최소화하기 위한 소음저감장치를 제공하는데 있다.Another object of the present invention is to provide a noise reduction device for minimizing the leakage of noise generated at the inlet of the compressor to the outside.

상기한 목적을 달성하기 위해, 본 발명은 압축기의 흡기구에 연통 설치되고, 흡입한 공기를 필터링하도록 내측에 에어필터를 갖는 소음저감장치에 있어서, 상기 에어필터의 상/하단을 각각 커버링함과 동시에 다수의 연결볼트를 통해 상호 에어필터를 사이에 두고 상호 고정되는 상부커버 및 하부커버와, 상기 에어필터 내측에 배치되며 일단이 상기 하부커버를 관통하여 외부로 노출되어 흡기구와 연통되는 소음부와, 상기 에어필터를 감싸고, 상기 상부커버 및 하부커버에 의해 상단 및 하단이 고정되는 투명 확인부와, 상기 에어필터 및 확인부 사이의 흡입채널로 공기를 유입하기 위해, 상기 상부커버 상에 흡입채널과 대응하는 부분에 형성된 다수의 흡입구멍을 포함하는 것을 특징으로 하는 압축기의 소음저감장치를 제공한다.In order to achieve the above object, the present invention is provided in communication with the intake port of the compressor, in the noise reduction device having an air filter inside to filter the sucked air, while covering the upper and lower ends of the air filter, respectively An upper cover and a lower cover which are fixed to each other with a plurality of connecting bolts interposed therebetween, a noise unit disposed inside the air filter and having one end exposed to the outside through the lower cover and communicating with an intake port; A transparent check unit surrounding the air filter and fixed to the upper and lower ends by the upper cover and the lower cover, and a suction channel on the upper cover to introduce air into the suction channel between the air filter and the check unit. It provides a noise reduction device for a compressor, characterized in that it comprises a plurality of suction holes formed in the corresponding portion.

이에 따라 본 발명은 확인부를 통해 소음저감장치를 분해할 필요 없이 외부에서 유안으로 에어필터의 오염여부를 용이하게 파악할 수 있다.Accordingly, the present invention can easily determine whether the air filter is contaminated with the eye from the outside without having to disassemble the noise reduction device through the confirmation unit.

또한, 상기 상부커버는 저면에 확인부의 상단이 삽입 고정되는 제1 슬롯이 돌출 형성되고, 상기 하부커버는 상면에 확인부의 하단이 삽입 고정되는 제2 슬롯이 돌출 형성되는 것이 바람직하다.In addition, it is preferable that the upper cover has a first slot protruding from the bottom of which the upper end of the identification part is inserted into and fixed, and the lower cover protrudes from a second slot through which the lower end of the identification is inserted into the upper surface.

상기 확인부의 내측에 소정 간격을 두고 부착된 다수의 흡음재를 더 포함함에 따라 실린더 내부에서 발생하는 소음을 흡수하여 외부로 나가는 소음을 최소화 할 수 있다.By further comprising a plurality of sound absorbing material attached to the inside of the check unit at a predetermined interval to minimize the noise to the outside to absorb the noise generated inside the cylinder.

이 경우, 상기 확인부는 투명부재와 흡음재가 교호로 배치되거 물론 가능하다.In this case, the checking unit is of course arranged alternately with the transparent member and the sound absorbing material.

이하, 첨부된 도면을 참고하여 본 발명의 제1 실시예에 따른 압축기의 소음저감장치의 구성을 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings illustrating a configuration of a noise reduction device of a compressor according to a first embodiment of the present invention.

도 1 및 도 2와 같이, 본 발명의 제1 실시예에 따른 소음저감장치는 필터부(31)와 필터부(31) 외주면에 결합된 철망(33)으로 이루어진 에어필터(30)를 구비하고, 상기 에어필터(30)는 그 상/하단이 각각 상/하부커버(11,13)에 의해 커버링됨과 동시에 고정된다. 이 경우, 상기 상/하부커버(11,13)는 다수의 연결볼트(15a∼15d) 및 너트(16a∼16d)에 의해 에어필터(30)를 사이에 두고 상호 고정됨에 따라, 상기 에어필터(30)는 연결볼트(15a∼15d)의 체결력에 의해 상/하부커버(11,13)에 의해 가압되면서 고정된다.1 and 2, the noise reduction device according to the first embodiment of the present invention is provided with an air filter 30 consisting of a filter unit 31 and a wire mesh 33 coupled to the outer peripheral surface of the filter unit 31 and The air filter 30 is fixed at the same time as the upper and lower ends thereof are covered by the upper and lower covers 11 and 13, respectively. In this case, the upper / lower covers 11 and 13 are fixed to each other with the air filter 30 interposed by a plurality of connecting bolts 15a to 15d and nuts 16a to 16d. 30 is fixed while being pressed by the upper / lower covers 11 and 13 by the fastening force of the connecting bolts 15a to 15d.

상기 에어필터(30) 내측에는 소음부(20)가 배치되며, 소음부(20)는 일단의 니플부(21)가 상기 하부커버(13)를 관통하여 외부로 노출됨과 동시에 고정너트(23)에 의해 하부커버(13)에 착탈 가능하게 고정된다. 이렇게 외부로 노출된 니플부(21)는 흡기구 측에 체결되어 필터링된 흡입공기를 흡기구로 안내하는 유로역할을 한다.The silencer 20 is disposed inside the air filter 30, and the silencer 20 is exposed to the outside by passing through the lower cover 13 at one end of the nipple portion 21 and fixing nuts 23. Removably fixed to the lower cover 13 by. The nipple portion 21 exposed to the outside is fastened to the intake port side and serves as a flow path for guiding the filtered suction air to the intake port.

이러한 소음부(20)는 에어필터(30)에 의해 필터링된 흡입공기를 한번 더 필터링함과 동시에 흡입구 내측 예를 들면 흡기밸브가 동작하는 실린더 블록 내에서 발생하는 소음이 소음저감장치 외부로 나가는 것을 방지할 수 있다. The silencer 20 filters the intake air filtered by the air filter 30 once more, and at the same time, the noise generated in the cylinder block inside the intake port, for example, the intake valve operates, goes out of the noise reduction device. You can prevent it.

한편, 확인부(40)는 상기 에어필터(30)와 소정 간격을 두면서 에어필터(30)를 감싸도록 배치된다. 상기 확인부(40)는 에어필터(30)와 마찬가지로 상/하부커버(11,13)에 의해 상/하단이 고정되며, 그 높이는 대략 에어필터(30)와 동일하게 이루어는 것이 바람직하다.On the other hand, the verification unit 40 is disposed to surround the air filter 30 at a predetermined interval from the air filter 30. Like the air filter 30, the check unit 40 is fixed to the upper and lower ends by the upper / lower covers 11 and 13, and the height thereof is preferably substantially the same as that of the air filter 30.

상기 확인부(40)는 내측에 배치된 에어필터(30)의 오염정도를 작업자가 별도의 작업없이 단지 육안으로만 확인이 가능하도록 투명 아크릴재로 이루어진다. 본 발명의 실시예에서는 확인부(30)를 아크릴로 예를 들어 설명하지만 아크릴에 제한되지 않으며, 소정의 내구성을 갖고 있으면서 투명한 재질을 갖는 재료이면 사용 가능하다.The check unit 40 is made of a transparent acrylic material so that the operator can check the contamination level of the air filter 30 disposed inside only by the naked eye without additional work. In the embodiment of the present invention, the confirmation unit 30 is described as an example of acryl, but is not limited to acryl, and may be used as long as it has a predetermined durability and a material having a transparent material.

또한, 상기 에어필터(30) 및 확인부(40) 사이에는 소음저감장치 내로 유입된 흡입공기를 에어필터(30)로 유입하기 위한 소정의 흡입채널(18)이 형성된다. 상기 흡입채널(18)로 외부 공기를 흡입하기 위해, 도 3과 같이 상기 상부커버(11) 상에는 흡입채널(18)과 대응하는 부분에 형성된 다수의 흡입구멍(17)이 형성된다.In addition, a predetermined suction channel 18 is formed between the air filter 30 and the checker 40 to introduce the suction air introduced into the noise reduction device into the air filter 30. In order to suck the outside air into the suction channel 18, a plurality of suction holes 17 formed in the portion corresponding to the suction channel 18 are formed on the upper cover 11 as shown in FIG. 3.

상기 다수의 흡입구멍(17)의 직경 및 그 개수는 압축기의 공기 압축성능을 고려하여 설정하는 것이 바람직하다.The diameter and the number of the plurality of suction holes 17 are preferably set in consideration of the air compression performance of the compressor.

이와 같이 구성된 본 발명의 제1 실시예에 따른 소음저감장치의 작용을 설명하면 다음과 같다.Referring to the operation of the noise reduction device according to the first embodiment of the present invention configured as described above are as follows.

압축기의 실린더 내의 피스톤(미도시)이 왕복운동을 하면서 흡입구(1) 측에 흡입력이 발생하면 외부 공기는 다수의 흡입구멍(17)을 통해 흡입채널(18, 도 2 참조)로 유입되고, 이렇게 유입된 공기는 에어필터(30)를 통과하여 내측으로 흡입된다.When a piston (not shown) in the cylinder of the compressor reciprocates and a suction force is generated on the suction port 1 side, outside air flows into the suction channel 18 (see FIG. 2) through the plurality of suction holes 17. Inflowed air passes through the air filter 30 and is sucked inward.

이 과정에서 공기는 에어필터(30)에 의해 먼지 등이 필터링되고, 먼지는 에어필터(30)의 외측 또는 내부에 잔류한다. 이와 같이 에어필터(30)에 잔류하는 먼지가 많아질수록 에어필터(30)의 외측은 오염부위가 확대되는데, 본 발명은 투명 확인부(40)를 통해 상기 에어필터(30)의 오염정도를 용이하게 확인할 수 있다.In this process, the dust is filtered by the air filter 30, and the dust remains outside or inside the air filter 30. As the amount of dust remaining in the air filter 30 increases, the outside portion of the air filter 30 is enlarged, and the present invention improves the degree of contamination of the air filter 30 through the transparent checking unit 40. It can be easily confirmed.

한편, 상기 에어필터(30)를 내측으로 유입된 공기는 소음부(20)를 통해 한번 더 필터링된 후, 소음부(20) 내측을 통해 흡입구(1)로 유입된다. 이때 상기 소음부(20)에 의해 압축기의 실린더 내에서 발생하는 소음이 흡기구(1)를 통해 외부로 나가는 것을 차단할 수 있다.Meanwhile, the air introduced into the air filter 30 is filtered once more through the silencer 20, and then flows into the inlet 1 through the inside of the silencer 20. At this time, the noise generated in the cylinder of the compressor by the silencer 20 can be prevented from going out through the inlet (1).

이 경우, 외부로 누출되는 소음을 한층 더 줄이기 위해, 도 4 및 도 5와 같 이 확인부(40) 내측에 소정 간격을 두고 다수의 흡음재(50)를 부착하는 것도 가능하다. 상기와 같이 흡음재(50)를 소정 간격으로 배치하는 이유는 외부에서 확인부(40)를 통해 에어필터(30)를 육안으로 확인할 수 있는 공간을 확보하기 위함이다.In this case, in order to further reduce the noise leaking to the outside, it is also possible to attach a plurality of sound absorbing material 50 at predetermined intervals inside the check unit 40, as shown in Figs. The reason for arranging the sound absorbing material 50 at predetermined intervals as described above is to secure a space where the air filter 30 can be visually checked through the check unit 40 from the outside.

이와 같은 다수의 흡음재(50)는 소음부(20)에서 미처 잡아내지 못한 소음을 최종적으로 흡수함으로써 압축기의 실린더 내의 소음이 외부로 누출되는 것을 최소한으로 줄일 수 있다.Such a plurality of sound absorbing material 50 can minimize the leakage of the noise in the cylinder of the compressor to the outside by finally absorbing the noise not detected by the silencer 20.

상기 다수의 흡음재(50)로는 폴리우레탄계, 폴리에스테르계, 멜라민계, 글라스울계 흡음재, 섬유판, 금속타공판 및 발포 알루미늄 중 어느 하나로 이루어진다.The plurality of sound absorbing materials 50 may be made of any one of polyurethane, polyester, melamine, glass wool sound absorbing material, fiber board, metal perforated plate, and foamed aluminum.

도 6은 본 발명의 제2 실시예를 나타내는 압축기의 소음저감장치의 종단면도이고, 도 7은 도 6에 도시된 하우징을 나타내는 사시도이다.FIG. 6 is a longitudinal sectional view of the noise reduction device of the compressor according to the second embodiment of the present invention, and FIG. 7 is a perspective view showing the housing shown in FIG.

본 발명의 제2 실시예에서는 전체적인 구성은 제1 실시예와 대부분 동일하며, 다만, 도 6과 같이, 상부커버(111)는 저면에 확인부(140)의 상단이 삽입되는 제1 슬롯(111a)이 돌출 형성되고, 하부커버(113)는 상면에 확인부(140)의 하단이 삽입되는 제2 슬롯(113a)이 돌출 형성된다.In the second embodiment of the present invention, the overall configuration is substantially the same as that of the first embodiment. However, as shown in FIG. 6, the upper cover 111 has a first slot 111a into which an upper end of the identification unit 140 is inserted. ) Is protruded, the lower cover 113 is protruded to form a second slot (113a) is inserted into the lower end of the check unit 140 on the upper surface.
