본 고안은 이동식 공기 압축기(Portable Air Compressor)에 사용되는 필터(이하 필터자 약칭함)의 개량 고안이다.The present invention is an improved design of a filter (hereinafter, abbreviated to filter) used in a portable air compressor.

공기 압축기는 암반굴착, (탄광·공사장), 식품업게 제약업계등 각종 산업분야에서 다양하게 활용된다.Air compressors are widely used in various industries such as rock excavation, (coal mining and construction), food industry and pharmaceutical industry.

고압의 압축 공기는 콤프래샤의 실린더내에서 피스톤에 의하여 압축, 송출 과정을 거치게 됨으로 미량의 윤활유가 혼입됨을 막을 수 없는 것이고, 이와 같은 윤활유 및 공기중의 수분을 제거하기 위하여 윤활유 및 수분회수용 필터를 사용하게 된다.The high pressure compressed air is compressed and discharged by the piston in the cylinder of the compressor to prevent the incorporation of a small amount of lubricating oil. In order to remove such lubricant and moisture in the air, the lubricating oil and the water recovery filter Will be used.

특히 윤활유의 회수를 철저히 해야하는 분야를 열거하면, 식품업계, 제약업계 반도체공자, 화학업체등 여러 분야를 들 수있다In particular, if you list the areas that need to thoroughly recover lubricants, there are many fields such as food industry, pharmaceutical industry semiconductor technicians, chemical companies, etc.

종래 공기 압축기용 공기 필터는 제1도에 예시된 바와 같이 공기 주입구(1) 및 배출구(2)를 갖는 케이스(3)내에 원통형 여과체(4)를 내장하고, 압축공기를 주입구(1) 및 방향 유도격판(5)을 거쳐 여과체(4)를 심층부에서 외측으로 통과 시킨 다음 배출구(2)로 안내되며, 모아진 윤활유 등의 찌꺼기는 케이스 상의 배출구(6)로 회수할 수 있게 된 것, 또는 제2도에서와 같이 주입구(1) 및 배출구(2)를 갖는 케이스(3)내에 원통형 여과체(4) 및 판상의 적층여과체(4')를 직렬로 접속 내장하고, 압축 공기를 주입구(1) 및 방향 유도 격판(5)을 거쳐 여과체(4)를 통과하게 하여 여과시키고 이어서 배출구(2)로 내보내는 것이었다.A conventional air filter for an air compressor includes a cylindrical filter body 4 in a case 3 having an air inlet 1 and an outlet 2, as illustrated in FIG. 1, and compressed air inlet 1 and The filter body 4 is passed through the directional guide plate 5 to the outside from the depth portion and then guided to the outlet 2, and the collected debris, such as lubricating oil, can be recovered to the outlet 6 on the case, or As shown in FIG. 2, a cylindrical filter member 4 and a plate-shaped laminated filter 4 'are connected in series in a case 3 having an inlet 1 and an outlet 2, and compressed air is injected into the inlet ( 1) and through the direction guide diaphragm (5) to pass through the filter body (4) and to filter and then to the outlet (2).

이와같은 필터들의 결점을 든다면 점도가 높은 윤활유를 직접 여과체에 접촉시킴에 따라 여과체는 짧은 시간내에 윤활유에 젖게된다.(여과체가 윤활유에 젖으면 에어필터의 기능을 상실하게 됨)The shortcomings of these filters are that the highly viscous lubricating oil is brought into direct contact with the filter and the filter is immersed in the lubricating oil within a short time (if the filter is wet, the air filter loses its function).

그리하여 여과체의 평균 수명이 1500시간 정도에 불과하며 이에 따라 운전비용은 증대되고 취약한 기계적 구성에 기인되어 쉽게 파손되는등의 결점을 지적할 수가 있는 것이다.Therefore, the average life of the filter medium is only about 1500 hours, and thus the operating cost is increased and the defects such as being easily broken due to the weak mechanical configuration can be pointed out.

본 고안은 여과체의 사용수명이 3000내지 4000시간 정도가 되는 경제성이 높은 필터이며, 견고한 기계적 구성으로 본체의 수명도 내구적이고 한편 여과체 바꾸기 작업이 간편한 공기 압축기용 필터인 것이다.The present invention is a highly economical filter with a service life of about 3000 to 4,000 hours, and is a filter for an air compressor that has a durable mechanical structure and a long life of the main body, and is easy to change the filter medium.

본 고안의 기술 구성을 요약하면 외부 케이스내에 유입된 고속의 압축공기는 다중의 안내격판으로 구성된 지그재그의 유로를 통과할때 질량과 점성이 큰 윤활유 입자가 격판에 접촉되어 제거되고(이하 접촉 제거라침함)이어서, 여과체 내부케이스 내에 안내되며, 여과체 내부케이스내에서는 1차 필터의 심층에서 외측으로 외향유로를 따라, 2차 필터에서는 외주면에서 심층으로 내향유로를 따라 반복 통과하는 동안 잔여 윤활유가 여과체에 흡수되게함(이하 다중 흡수제거라칭함)으로써 청정한 압축 공기를 얻을 수 있을뿐 아니라 여과체의 사용수명을 배가하며, 내외층의 2중 케이스 구조를 갖게됨에 따라 견고함은 물론 분해조립의 조작이 간편하게된 것이다.In summary, the high-speed compressed air introduced into the outer case is removed by contacting the diaphragm with high mass and viscosity of lubricating oil particles when passing through the zigzag flow path composed of multiple guide plates. ), Which is guided into the inner case of the filter medium, and in the inner case of the filter medium, residual lubricant flows through the inward flow path from the outer periphery of the primary filter to the outer side and in the secondary filter from the outer circumferential surface to the depth. By being absorbed by the filter body (hereinafter referred to as multi-absorption elimination), not only can you obtain clean compressed air, but also double the service life of the filter medium, it has a double casing structure of the inner and outer layers, it is not only robust, but also It is easy to operate.

본 고안을 첨부도면에 따라서 상세하게 설명하면 다음과 같다.Referring to the present invention in detail according to the accompanying drawings as follows.

케이스는 내부케이스(10)와 외부케이스(20)의 2중 구조이며, 외부케이스(20)에는 일측의 주입구(21), 타측의 플랜지형덮개(22)상에 배출굼(23)을 갖고 다시, 주입구(21)측에 다중의 격판(24)과 안내구멍(24')으로 조합된 지그재그유로(25) 및 상폐(常閉)상태인 제1회수 밸브(26)를 갖는다.The case is a double structure of the inner case 10 and the outer case 20, the outer case 20 has the discharge port 23 on the inlet 21 of one side, the flange-shaped cover 22 of the other side again And a zigzag flow passage 25 combined with a plurality of diaphragms 24 and guide holes 24 'on the injection port 21 side, and a first recovery valve 26 in a closed state.

내부 케이스(10)는 다중의 흡수제거 기구로서 외부케이스속에 내장되며 외측의 기저판(11)이 외부케이스와 덮개 사이에 물려 고정되고, 1차 여과체(12)는 내관판(13)에 고정되어 심부에서 외측으로 흐르는 외향유로(14)를 구성하였으며, 2차 여과체(15)는 외단판(16)상에 고정되어 배출구(23)와 연통되는 내향유로(17)를 구성하였고, 상폐 상태인 제2회수 밸브(18)를 갖는 구성인 것이다.The inner case 10 is embedded in the outer case as multiple absorption removal mechanisms, and the outer base plate 11 is fixed between the outer case and the cover, and the primary filter body 12 is fixed to the inner tube plate 13. The outward flow passage 14 which flows outward from the core portion is constituted, and the secondary filter body 15 is fixed on the outer end plate 16 to form an inward flow passage 17 which communicates with the outlet 23, and is in a closed state. It is a structure which has the 2nd recovery valve 18 which is phosphorus.

한편 여과체(12) (15)의 세부 구성을 보면 내측으로부터 내부지지 원통(40) (다공성임), 여과지와 그물망(41), 석면(4)(유리성분이 없는것), 중간삽입 원통(43) (다공성임), 석면(44) 및 외부지지원통(45)의 적층으로 구성되어 있는 것이고 실시예에 의하면 지지원통은 직경 0.8미리의 구멍을 1미리 간격으로 배열하여된 것이다.On the other hand, the detailed structure of the filter bodies 12 and 15 shows the inner support cylinder 40 (which is porous) from the inside, the filter paper and the mesh 41, the asbestos 4 (without the glass component), and the intermediate insertion cylinder 43. (Porous), asbestos 44 and the outer support cylinder 45, and in accordance with the embodiment, the support cylinder is a hole with a diameter of 0.8 millimeters arranged at intervals of 1 millimeter.

본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention is as follows.

콤프레사로부터 생성되는 압축공기는 주입구(21)에 접속하여 윤활유 및 공기중의 수분을 제거하고 청정된 공기는 배출구(23)를 통하여 필터에서 배출되며 회수된 윤활유 또는 수분등의 폐기물을 제1회수밸브(26) 및 제2회수 밸브(18)를 열어 필터 밖으로 뽑아낼 수 있는 것이다.Compressed air generated from the compressor is connected to the inlet 21 to remove lubricating oil and water from the air, and the purified air is discharged from the filter through the outlet 23 to recover the recovered waste oil such as lubricating oil or water. The valve 26 and the second recovery valve 18 can be opened and pulled out of the filter.

윤활유의 제거 작용을 관찰하면 콤프레샤에서 공급되는 속도가 빠른 압축공기는 당중격판(24) 및 안내구멍(24)으로 구성된 지그재그 유로(25)를 통과하면서 질량 및 점도가 큰 윤활유 미접자가 격판에 포착된다. 포착된 윤활유는 격판(24)을 적시며 중력의 방향에 따라 흐르고 외부케이스(20)내에 고여 있다가 회수되는 것이다. (입자가 큰 수증기는 접촉제거시에 제거되기도하나 대부분 여과체에서 흡착제거된다)When lubricating oil is observed, high-speed compressed air supplied from the compressor passes through a zigzag flow path 25 composed of a sugar medium plate 24 and a guide hole 24, and a large amount of lubricating oil and a large amount of lubricating oil are caught on the diaphragm. do. The captured lubricant flows along the direction of gravity and wets the diaphragm 24 and is collected in the outer case 20 and then recovered. (Particulate water vapor may be removed at the time of contact removal, but most adsorption is removed from the filter medium.)

이와 같은 접촉제거에 의하여 대분분의 윤활유는 회수되는 것이며 이제는 나머지 잔여 윤활유 및 수분의 제거를 위하여 다중 흡수제거 기구인 내부원통(10)에 공급되는 것이다.By this contact removal, most of the lubricating oil is recovered and is now supplied to the inner cylinder 10, which is a multi-absorption removal mechanism, for removing the remaining residual lubricating oil and water.

내부 원통에 이른 압축공기는 1차여과체(12)의 외향유로(14)를 흐르는 동안 잔여 윤활유 및 수증기의 입자가 흡수되고 다시, 2차여과체(15)에 이르러 내향유로(17)를 거치면서 청정한 공기로 여과 되는 것이다.The compressed air reaching the inner cylinder is absorbed by the residual lubricant and water particles while flowing through the outward flow passage 14 of the primary filter body 12, and then reaches the secondary filter body 15 to direct the inward flow passage 17. As it passes, it is filtered with clean air.

여과된 공기는 배출구(23)를 통해 필터 밖으로 나가며, 1, 2차 여과체에서 흡착제거시 포착되어 내부케이스(10)내에 고이는 폐기물을 제2회수밸브(18)를 열고 제거할 수 있는 것이다.The filtered air is discharged out of the filter through the outlet 23, and the waste collected in the adsorption and removal of the primary and secondary filters is collected in the inner case 10 so as to open and remove the second recovery valve 18.

한편, 필터는 내부케이스(10)와 외부 케이스(20)로된 2중의 구조이고 내부케이스의 기저판(11)이 외부케이스(20)와 플랜지형 덮개 사이에 물려 고정되는 구조로서 견고한 구성임은 물론 분해 조립이 용이하며 여과체를 교체하기도 쉬운 것이고, 여과체는 내, 외부 지지원통 중간 삽입원통(43) 사이에 석명(42) (44), 여과지와 그물망(41)을 삽입한 다층 구조이므로 제작은 쉽고 윤활유가 흡착되어도 여과 저항이 적어 성능 좋은 흡착 효율을 내구적으로 지속할 수 있는 것이다.On the other hand, the filter is a double structure consisting of the inner case 10 and the outer case 20 and the base plate 11 of the inner case is a structure that is fixed between the outer case 20 and the flange-like cover is a solid configuration, of course It is easy to disassemble and assemble, and it is easy to replace the filter medium, and the filter medium is made of a multi-layer structure in which the transparent 42, 44, filter paper and the mesh 41 are inserted between the inner and outer support cylinder intermediate insertion cylinders 43. It is easy and durable even if the lubricating oil is adsorbed and the filtration resistance is low, and the performance of the adsorption is good.
