Description

철도차량용 공기정화장치{Air cleaner of railway train}Air cleaner for railway vehicles {Air cleaner of railway train}

본 고안은 철도차량용 공기정화장치에 관한 것으로서, 보다 상세하게는 철도차량의 제동장치에 설치되어 압축공기 중에 포함된 이물질을 자동적으로 배출할 수 있도록 한 철도차량용 공기정화장치에 관한 것이다.The present invention relates to an air purifier for a railroad car, and more particularly, to an air purifier for a railroad car, which is installed in a brake of a railroad car to automatically discharge foreign substances contained in compressed air.

철도차량의 제동장치에는 압축공기에 포함된 이물질을 걸러주는 공기정화장치가 마련되는데, 최근에는 필터에 의해 걸러진 이물질을 자동적으로 배출되도록 하는 공기정화장치가 개발되어 국내 실용신안등록출원 제 93-12158호에 개시된바 있다.An air purifying device for filtering foreign matters contained in compressed air is provided in a brake system of a railway vehicle. Recently, an air purifying device for automatically discharging foreign substances filtered out by a filter has been developed. It is disclosed in the call.

이러한 공기정화장치는 도 1에서와 같이, 공기유입구(61)와 연통되며 중앙에는 1차필터(71)를 갖는 1차공기정화실(64)과, 상기 1차공기정화실(64) 직하방에 마련된 공기와류실(62)과, 상기 1차공기정화실(4)과 연통되며 중앙에는 2차필터(72)가 구비된 2차공기정화실(65)과, 상기 2차공기정화실(65)과 연통되는 공기송출구(66)와, 상기 공기와류실(62)의 직하방에 마련된 오물유집실(63)과, 상기 오물유집실(63)에 모인 오물을 배출시키기 위한 개폐봉(73)과, 이 개폐봉(73)을 작동시키기 위해 실린더(75)에 설치되며 내부에는 공기유입세공(81)이 형성된 피스톤(80)과, 상기 실린더(75)와 연통되는 공간부(68)와, 상기 2차공기정화실(65)과 공간부(68)를 연통시켜 주는 통로(67)와, 상기 피스톤(80)의 일측에 형성되며 압축공기를 저장하여 철도차량의 브레이크 동작시 피스톤(80)의 후퇴시키기 위한 압축공기실(69)을 각각 구비하여서 된 것이다.1, the air purifying apparatus communicates with the air inlet 61 and directly under the primary air purifying chamber 64 having the primary filter 71 at the center, and directly below the primary air purifying chamber 64. And a secondary air purification chamber (65) having a secondary filter (72) at the center and in communication with the air vortex chamber (62) provided in the air filter, and the primary air purification chamber (4). An air outlet 66 communicating with 65, a waste collection chamber 63 provided directly below the air swirl chamber 62, and an opening / closing rod for discharging the waste collected in the waste collection chamber 63; 73, a piston 80 installed in the cylinder 75 to operate the opening and closing rod 73, the air inlet hole 81 formed therein, and the space portion 68 in communication with the cylinder 75 And a passage 67 for communicating the secondary air purification chamber 65 and the space portion 68, and a piston formed at one side of the piston 80 to store compressed air so as to store the compressed air during a brake operation of the railway vehicle. 80) Each of them has a compressed air chamber 69 for retreating.

따라서, 공기유입구(61)를 통해 유입되는 압축공기는 공기와류실(62) 내에서 와류현상을 일으키면서 공기 중에 포함된 이물질은 원심력에 의해 낙하되어 오물유집실(63)에 집적되고 공기는 1차공기정화실(64)의 1차필터(71)와 2차공기정화실(65)의 2차필터(72)를 거치면서 여과된 후 연통된 공기송출구(66)를 통해 철도차량의 공기저장탱크로 압송된다.Therefore, the compressed air introduced through the air inlet 61 causes vortexing in the air vortex chamber 62, and foreign matter contained in the air is dropped by centrifugal force and accumulated in the waste collection chamber 63, and the air is 1. After passing through the primary filter 71 of the secondary air purifying chamber 64 and the secondary filter 72 of the secondary air purifying chamber 65, the air of the railway vehicle is communicated through the air outlet 66 communicated with each other. Are transported to storage tanks.

이와 같이 공기정화기능이 행해질 때 2차공기정화실(65)에 유입된 고압의 공기는 통로(67)와 공간부(68) 및 피스톤의 공기유입세공(81)을 거쳐 압축공기저장실(69)에 충진된다. 또한, 압축공기저장실(69)내의 공기압과 공간부(68)의 공기압이 동일하게 되면 스프링(83)의 탄발력에 의해 피스톤(80)이 전진하게 되며 피스톤(80)에 연결된 개폐봉(73)이 전진되어 개폐구(74)를 닫게 된다.When the air purifying function is performed as described above, the high-pressure air introduced into the secondary air purification chamber 65 passes through the passage 67, the space portion 68, and the air inlet hole 81 of the piston. Is filled in. In addition, when the air pressure in the compressed air storage chamber 69 and the air pressure of the space 68 are equal, the piston 80 is advanced by the spring force of the spring 83, and the opening and closing rod 73 connected to the piston 80 is provided. This advances to close the opening and closing port 74.

한편, 기관실에서 비상브레이크를 작동시키게 되면 도면에 도시되지 않은 제동장치의 공기이송관 내의 압축공기가 배출되어 압력이 급격히 저하되면서 순간적으로 압축공기저장실(69)을 제외한 모든 공간의 공기가 공기유입구(61)를 통해 빠져나가게 되므로 피스턴(80)이 압축공기저장실(69)의 압력에 의해 후퇴되면서 개폐봉(73)을 후퇴시켜 오물배출용 개폐구(74)를 개방하게 되며, 오물유집실(63) 내에 모인 오물을 공기압력에 의하여 강제로 배출시키게 된다.On the other hand, when the emergency brake is operated in the engine room, the compressed air is discharged in the air transfer pipe of the braking device, not shown in the drawing, and the pressure is drastically reduced, and the air in all the spaces except the compressed air storage room 69 is instantaneously introduced. Since the piston 80 is retracted by the pressure of the compressed air storage chamber 69, the retracting rod 73 is retracted to open the opening / closing opening 74 for waste discharge, and within the waste collection chamber 63. Collected dirt is forced out by air pressure.

그러나, 이러한 구조의 공기정화장치는 그 구조가 매우 복잡하며 부품수가 증가되어 재료의 낭비를 초래할 뿐만 아니라, 이를 제조 및 조립하기가 어려워 제품의 생산단가가 현저히 상승되는 문제점이 있다. 또한, 이와 같이 부품수가 많아짐에 따라 그 구성품 중 어느 하나의 부품이 원활하게 작동되지 않게 되면, 전체적으로 불량율이 증가되는 문제점이 있다.However, the air purifier of such a structure has a problem that the structure of the air purifier is very complicated and the number of parts is increased, leading to waste of materials, and it is difficult to manufacture and assemble it, thereby significantly increasing the production cost of products. In addition, as the number of parts increases as described above, if any one of the components does not operate smoothly, there is a problem that the overall defective rate increases.

또한, 상기 공기정화장치는 장치내의 압축공기 배출속도가 공기 유입세공(81)을 통해 배출되는 압축공기의 배출속도보다 현저히 클 경우 피스톤(80)이 압축공기 저장실(69)의 압력에 의해 스프링(83)의 탄성력을 이기고 공간부(68)쪽으로 밀리면서 이물질을 배출할 수 있도록 되어 있므로, 일반 제동시에는 작동되기 어려우며, 급제동시에만 작동되는 단점이 있다.In addition, the air purifier is a spring 80 (by the pressure of the compressed air storage chamber 69 when the compressed air discharge rate in the apparatus is significantly greater than the discharge rate of the compressed air discharged through the air inlet hole 81) It is difficult to operate during normal braking because it is capable of discharging foreign matters while pushing the elastic force of 83) and pushing toward the space portion 68, and has a disadvantage in that it operates only during rapid braking.

더욱이, 상기 공기정화장치는 1차 및 2차 필터(71,72)가 직렬로 설치되기 때문에 그 만큼 공기의 저항력이 증가되어 급제동시에도 장치 내부에 급격한 감압현상이 발생되지 않아 오물유집실(63)에 모인 이물질을 원활하게 배출시키지 못하는 문제점이 있다.In addition, since the air purifier has the primary and secondary filters 71 and 72 installed in series, the resistance of the air is increased so that a sudden depressurization does not occur in the apparatus even during sudden braking. There is a problem that does not smoothly discharge the foreign matter gathered in).

또한, 이와 같이 오물유집실(63)에 모인 먼지 등이 외부로 원활하게 배출되지 않게 되면, 먼지 등의 이물질이 압축공기에 의해 공기와류실(62) 내부를 순환하다가 필터(71,72)에 걸려 눈메꿈현상을 유발시키게 되므로, 원활한 정화기능을 할 수 없는 문제점이 있다.In addition, when the dust collected in the waste collection chamber 63 is not smoothly discharged to the outside, foreign matter such as dust circulates inside the air vortex chamber 62 by compressed air, and then passes through the filters 71 and 72. It will cause the eyes hanging, there is a problem that can not be a smooth purification function.

본 고안은 전술한 바와 같은 문제점을 해결하기 위한 것으로서, 본 고안의 목적은 간단한 구조로 이루어져 제조 및 조립이 용이하고, 불량율이 저하되며, 급제동시에는 물론 일반제동시에도 걸러진 이물질을 배출해주므로써, 원활한 정화기능을 수행할 수 있도록 된 철도차량용 공기정화장치에 관한 것이다.The present invention is to solve the problems as described above, the purpose of the present invention is made of a simple structure, easy to manufacture and assembly, the failure rate is reduced, by discharging the foreign matter filtered during rapid braking as well as during normal braking, The present invention relates to an air purifying device for a railroad car capable of performing a smooth purification function.

상기 개폐봉(20)은 오물유집실(13)의 개폐구(14)에 설치되어 실린더(16) 내부로 연장되며 그 상단부 내측에는 걸림턱(27)이 형성되고 이 걸림턱(27) 아래의 외주면에는 상단으로부터 연통된 공기세공(26)이 형성된다.The opening and closing rod 20 is installed in the opening and closing hole 14 of the waste collection chamber 13 and extends into the cylinder 16, the upper end of the engaging jaw (27) is formed and the outer peripheral surface below the engaging jaw (27) The air hole 26 communicated from the upper end is formed.

상기 제1피스톤(40)은 개폐봉(20)의 걸림턱(27) 상부에 슬라이드되도록 결합되어 실린더(16)의 공기유입공(19) 아래쪽에 수평방향으로 설치되어 공기 유입시 개폐봉(20)을 아래로 밀어주는 역활을 한다. 상기 제2피스톤(45)은 개폐봉(20)의 선단과 접해지도록 실린더(16)의 공기유입공(19) 위쪽에 수평방향으로 설치되고 그 내부에는 공기세공(46)이 형성되어 급격한 감압시 개폐봉(20)을 아래로 밀어주는 역할을 한다.The first piston 40 is coupled to slide on the top of the locking jaw 27 of the opening and closing rod 20 is installed in the horizontal direction below the air inlet hole 19 of the cylinder 16 to open and close the rod (20) ) To push down. The second piston 45 is installed in the horizontal direction above the air inlet hole 19 of the cylinder 16 to be in contact with the front end of the opening and closing rod 20 and the air pore 46 is formed therein when sudden decompression The opening and closing rod 20 serves to push down.

따라서, 공기유입구(11)를 통해 유입되는 압축공기는 공기정화실(15)의 외벽에 부딪쳐 공기와류실(12) 내에서 와류현상을 일으키면서 공기에 함유된 이물질은 원심력에 의해 공기와류실(12)의 하부로 낙하되어 오물유집실(13)에 집적되고 공기는 공기정화실(15)의 필터(50)를 통과하면서 여과되어 공기송출구(18)를 통해 철도차량의 공기저장탱크로 압송된다.Therefore, the compressed air introduced through the air inlet 11 hits the outer wall of the air purifying chamber 15, causing vortexing in the air vortex chamber 12, and the foreign matter contained in the air is caused by the centrifugal force of the air vortex chamber ( 12 is dropped to the lower part of the dust collection chamber 13, the air is filtered while passing through the filter 50 of the air purification chamber 15, and is conveyed to the air storage tank of the railway vehicle through the air outlet (18) do.

이와 같은 과정에서 압축공기는 도 3에 도시된 바와 같이, 공기유입공(19)을 통해 실린더(16) 내부로 유입되어 제1피스톤(40)을 하강시켜 개폐봉(20)을 아래쪽으로 밀어주어 개폐구(14)를 개방하게 되며, 오물유집실(13)에 모인 이물질이 외부로 배출되도록 한다. 계속해서 실린더(16)로 유입된 압축공기는 공기세공(26,46)을 통해 제2피스톤(45) 상부의 압축공기저장실(17)과 제1피스톤(40) 하부의 실린더(16)에 채워져 각 피스톤(40,45)의 상하부 압력이 균형을 이루게 되며 개폐봉(20)이 스프링(25)의 탄성력에 의해 상부로 밀어올려지면서 개폐구(14)를 닫게 된다.In this process, as shown in FIG. 3, the compressed air flows into the cylinder 16 through the air inlet 19 to lower the first piston 40 to push the opening / closing rod 20 downward. Opening and closing the opening 14, the foreign matter collected in the waste collection chamber 13 is to be discharged to the outside. Then, the compressed air introduced into the cylinder 16 is filled in the compressed air storage chamber 17 above the second piston 45 and the cylinder 16 below the first piston 40 through the air holes 26 and 46. The upper and lower pressures of the pistons 40 and 45 are balanced, and the opening and closing rod 20 is pushed upward by the elastic force of the spring 25 to close the opening and closing hole 14.

이러한 압축공기 유입과정은 비상제동시는 물론 일반제동시에도 제동이 해제되면 자동적으로 이루어지는 것이므로, 오물유집실(13)에 모인 이물질이 원활하게 배출된다.The compressed air inflow process is automatically made when the braking is released during emergency braking as well as during emergency braking, and foreign matter collected in the waste collection chamber 13 is smoothly discharged.

또한, 기관실에서 비상브레이크를 작동시키게 되면, 제동장치의 공기이송관 내의 압력이 급격히 저하되면서 순간적으로 압축공기저장실(17)을 제외한 모든 공간에서의 공기가 공기유입구(11)를 통해 빠져나가게 되므로 제2피스톤(45)이 압축공기저장실(17)의 압력에 의해 밀리되면서 개폐봉(20)을 밀어내려 오물유집실(13)의 개폐구(14)를 개방하게 되며, 이물질을 공기압력에 의하여 강제로 배출시키게 된다.In addition, when the emergency brake is operated in the engine room, the pressure in the air transfer pipe of the braking device is drastically lowered, and the air in all spaces except the compressed air storage room 17 is instantly released through the air inlet 11. As the piston 45 is pushed by the pressure of the compressed air storage chamber 17, the piston 45 pushes the opening / closing rod 20 to open the opening / closing opening 14 of the waste collection chamber 13, and the foreign matter is forcibly discharged by the air pressure. Let's go.
