본 발명은 에프터 쿨러의 응축수 드레인 장치에 관한 것으로서, 에어 콤프레샤(air compressor)에서 생성되는 압축공기를 각종 공압기기에 공급함에 있어, 압축공기 냉각시 압축공기에 포함된 수중기 형태의 수분에 의해 발생되는 응축수를 자동·배수할 수 있도록 한 에프터 쿨러의 응축수 드레인 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a condensate drain device of an after cooler, and is supplied by various types of pneumatic equipment in compressed air generated by an air compressor, and is generated by water in the form of submerged water contained in the compressed air during cooling of the compressed air. The present invention relates to a condensate drain device of an after cooler capable of automatically and draining condensate.

현대사회는 고도한 기술의 발달로 인해 산업현장 설비가 무인자동화 시스템으로 바뀌어 가고 있는 추세이므로 이를 실현하기 위한 수단으로는 많은 전자부품과 각종 산업기기가 요구되는바, 특히, 산업기기에 있어서 유·공압을 이용한 공압기기는 경제성과 안전성이 우수하여 산업전반에 걸쳐 널리 사용되고 있으며, 이러한 공압기기의 동력원으로는 압축공기가 사용되며, 압축공기는 에어 콤프레샤에 의해 생성된다.In modern society, due to the development of advanced technology, industrial facilities are changing to unmanned automation system, so many electronic parts and various industrial devices are required as a means for realizing them. Pneumatic equipment using pneumatics is widely used throughout the industry because of its excellent economy and safety, compressed air is used as a power source of such pneumatic equipment, and compressed air is generated by an air compressor.

현재, 에어 콤프레샤에 의해 생성된 압축공기는 에어공급관을 통해 각종 공압기기에 직접공급되거나 또는 에어필터에 의해 정화 및 수분이 제거된 상태로 공급되어 공압기기의 작동이 이루어지고 있으나, 압축공기는 콤프레샤에 의한 생성과정에서 대기중의 수중기상태의 수분이 공기와 함께 압축되므로 소정의 수분이 함유된 상태이고 압축과정에서 발생되는 열에 의해 비교적 고온상태이므로 수분이 함유되고 비교적 고온 상태인 압축공기가 공압기기에 직접공급되어 사용될 경우에는 수분에 의한 공압기기의 오동작 및 수명단축을 초래하게 되는 폐단을 안고 있으며, 필터에 의한 압축공기의 정화 및 수분제거율(에어휠터에 의한 수분제거·흡수율은약 40%정도 내외)이 높지 않아 전자인 압축공기의 직접공급시 발생되는 폐단이 해소되지 못하여 원할한 공압기기의 작동이 이루어지지 않게 되는 문제점을 갖게 되었다.At present, the compressed air generated by the air compressor is directly supplied to various pneumatic equipment through the air supply pipe or supplied with the purified and water removed by the air filter, but the compressed air is operated. Since the water in the air in the air is compressed with the air during the production process by the air, the compressed air containing moisture and the relatively high temperature is pneumatic because it is in a state of high temperature by heat generated during the compression process. When directly supplied to the equipment, it has a closed end that may cause malfunction of the pneumatic equipment and shorten the life of the pneumatic equipment. Purification of compressed air by the filter and moisture removal rate (water removal and absorption rate by the air filter is about 40%) Because it is not high, it is not possible to solve the end that occurs when directly supplying compressed air which is electron. There is a problem that the operation of the limiting pneumatic equipment is not made.

또한, 구동모우터와 휀을 이용하여 에어 콤프레샤로부터 생성된 압축공기를 냉각·응축시켜 수분을 제거하기 위한 에프터 쿨러에서는 압축공기의 수분제거시 발생되는 응축수 배출 작업이 수작업에 의해 이루어지게 되므로 항시 일정시간마다 일일이 응축수를 체크하여 배출을 위한 밸브 개폐작업을 행해야 되므로 번거로움이 수반되었다.In addition, in the after cooler for removing moisture by cooling and condensing the compressed air generated from the air compressor using the driving motor and the fan, the condensed water discharged during the removal of the moisture of the compressed air is always performed by hand. It was cumbersome to check the condensate every hour and to open and close the valve for discharge.

본 발명은 상기와 같은 종래에서 수반되어지는 문제점을 해결하기 위한 것으로서, 그 목적은 에어콤프레샤에 의해 생성·공급되어지는 압축공기를 구동모우터에 의해 회동되는 팬(fan)을 이용하여 고온상태로 공급되어지는 압축공기를 냉각(열교환에 의한 냉각)시켜 압축공기에 수중기 상태로 함유된 수분을 냉각·응축시켜 응축수로 자동·배수시킬 수 있도록 된 새로운 형태의 에프터 쿨러의 응축수 드레인장치를 제공하고자 하는 것이다.The present invention is to solve the problems associated with the prior art as described above, the object of which is to produce a high-temperature state by using a fan (rotation) is rotated by the drive motor compressed air generated and supplied by the air compressor To provide a condensate drain device for a new type of after cooler that cools (compresses by heat exchange) the compressed air to be supplied and cools and condenses the water contained in the compressed air in the state of underwater. It is.

이와 같은 목적을 달성하기 위하여, 본 발명은 에어 콤프레샤에서 생성된 압축공기를 공압기기에 공급함에 있어서, 원통형상으로 하단이 폐쇄되고 일측방에 다수개의 분기관이 연통·결합된 메인 공급관에 의해 압축공기가 순환·공급되는 에프터 쿨러에 있어 상기 메인 공급관 하부에 연통·결합되는 배출관에 의해 볼 밸브가 설치되되, 볼 밸브의 개폐레버 양쪽 측단부에는 전기적인 신호에 의해 로드가구동되는 솔레노이드와 코일스프링이 결합된 응축수 드레인 장치가 구비된 특징을 갖는다.In order to achieve the above object, the present invention provides a compressed air generated by the air compressor to the pneumatic equipment, the lower end is closed in a cylindrical shape and compressed by the main supply pipe in which a plurality of branch pipes are connected and coupled to one side.

도 2는 본 발명에 따른 응축수 드레인 장치를 나타내는 평단면도로서, 구동모우터(도면에 도시되지 않음)에 의해 회전되는 휀(F)이 내설된 몸체부(20)에는 메인 공급관(3)과 연통·결합된 분기관(2)이 횡방향으로 설치되고 배출관(11) 선단부에 설치된 볼 밸브(12)의 개폐레버(13) 일측단부에는 고정브라켓(18)에 의해 지지된 솔레노이드(15)의 로드(14)가 링크(17)에 의해 결합되며 타측단부에는 코일스프링(16)의 일단이 끼워져 결합된 것을 나타내는 것이다.FIG. 2 is a plan sectional view showing a condensate drain device according to the present invention, and communicates with the main supply pipe 3 to a body portion 20 in which a fan F is rotated by a driving motor (not shown). A rod of the solenoid 15 supported by the fixing bracket 18 at one end of the opening / closing lever 13 of the ball valve 12 installed at the distal end of the branched pipe 2 coupled to the transverse direction. 14 is coupled by the link 17, and the other end thereof is fitted with one end of the coil spring 16 fitted thereto.

도 3(a), (b)는 본 발명에 따른 응축수 드레인 장치의 볼 밸브 작동상태를 설명하기 위한 개략 단면도로서, 도 3(a)는 볼 밸브(12)가 폐쇄(잠김)된 상태를 나타내는 것이고, 도 3(b)에서는 볼 밸브(12)가 개방(열림)된 상태를 나타내는 것이다.Figure 3 (a), (b) is a schematic cross-sectional view for explaining the ball valve operating state of the condensate drain device according to the present invention, Figure 3 (a) shows a state in which the ball valve 12 is closed (locked). In FIG. 3B, the ball valve 12 is opened (opened).

도 3(b)에서와 같이, 볼 밸브(12)의 개방은 제어부(통상의 전기신호장치로서 도면에는 도시되지 않음)로부터 전기적인 신호에 의해 솔레노이드(15)의 로드(14)가 구동(후진이동)됨에 따라 이에 링크(17)로 결합된 볼 밸브(12)의 개폐레버(13)가 고정점을 기점으로 회동(고정점을 기점으로 양쪽단부가 반대방향으로 회동됨)되어 볼 밸브(12)가 개방되는 것이다.As shown in Fig. 3B, the opening of the ball valve 12 is driven by the rod 14 of the solenoid 15 driven by an electrical signal from a control unit (usually an electric signal device, not shown in the drawing). As a result, the opening / closing lever 13 of the ball valve 12 coupled to the link 17 is rotated from the fixed point (both ends are rotated in the opposite direction from the fixed point) and the ball valve 12 ) Is open.

이때, 솔레노이드(15) 구동에 의해 개폐레버(13)가 회동됨에 따라 이와 반대쪽 측단부에 결합된 코일스프링(16)이 인장되어 소정의 반발력(압축)을 갖게 됨에 따라, 전기적인 신호가 멈추게 되면 개폐레버(13)는 코일스프링(16)의 반발력에 의해 다시 역방향(도 3a 참조)으로 회동되어 볼 밸브(12)가 폐쇄된다.At this time, as the opening and closing lever 13 is rotated by driving the solenoid 15, the coil spring 16 coupled to the opposite side end is tensioned to have a predetermined repulsion force (compression). The opening / closing lever 13 is rotated again in the reverse direction (see FIG. 3A) by the repulsive force of the coil spring 16 to close the ball valve 12.

도 4는 본 발명에 따른 응축수 드레인 장치가 설치된 에프터 쿨러를 나타내는 개략도로서, 에어 콤프레샤(CP)로부터 생성된 압축공기가 공급관(P)을 통하여 에프터 쿨러(1)를 거치면서 압축공기에 포함된 수분이 제거된 후, 에어 필터(AF)에서 정화된 후 공압기기(AM)로 공급되는 것을 나타내는 것이다.4 is a schematic view showing an after cooler in which a condensate drain device according to the present invention is installed, wherein the compressed air generated from the air compressor CP passes through the after cooler 1 through a supply pipe P. After this is removed, the filter is purified by the air filter AF and then supplied to the pneumatic device AM.

이때, 에프터 쿨러(1)의 일측 하단부에는 드레인 장치(10)가 설치되어 에프터 쿨러(1)에 의한 압축공기의 수분 제거시 발생된 응축수를 자동·배출시키게 된다.At this time, the drain device 10 is installed at one lower end of the after cooler 1 to automatically discharge and discharge the condensed water generated when water is removed from the compressed air by the after cooler 1.

이와 같은 본 발명의 사용상태를 설명하면 다음과 같다.Referring to the use state of the present invention as follows.

도 1 내지 도 4에 도시된 바와 같이, 에어 콤프레샤(C)에 의해 생성된 압축공기를 공압기기(AM)에 공급함에 있어, 압축공기에 포함된 수분을 제거하려면, 먼저, 에프터 쿨러(1)의 메인 공급관(3) 하부에 볼 밸브(12)가 설치된 배출관(11)을 연통·결합시키되, 볼 밸브(12)의 개폐레버(13) 양쪽 측단부에는 전기적인 신호에 의해 로드(14)가 구동되는 솔레노이드(15)와 코일스프링(16)을 결합하여 응축수 드레인 장치(12)를 도 4에 도시된 바와 같이, 에어 콤프레샤(CP)에 연결된 공급관(P)에 연결·설치한다.1 to 4, in order to remove the water contained in the compressed air in supplying the compressed air generated by the air compressor (C) to the pneumatic device (AM), first, the after cooler (1) The discharge pipe 11 in which the ball valve 12 is installed in the lower part of the main supply pipe 3 of the ball valve 12 is connected and coupled, and the rod 14 is connected to both ends of the opening / closing lever 13 of the ball valve 12 by an electrical signal. The driven solenoid 15 and the coil spring 16 are combined to connect and install the condensate drain device 12 to the supply pipe P connected to the air compressor CP, as shown in FIG. 4.

이와 같이, 응축수 드레인 장치(10)가 구비된 에프터 쿨러(1)가 설치되면, 에어 콤프레샤(CP)에 의해 생성된 압축공기는 공급관(P)을 통해 에프터 쿨러(1)를 거치면서 압축공기에 포함된 수분이 제거된 후, 에어 필터(AF)에서 2차 정화(압축공기에 포함된 미세한 이물질 따위를 제거함)된 상태로 공압기기(AM)에 공급되어 공압기기(AM)가 구동되는 것이다.As such, when the after cooler 1 equipped with the condensate drain device 10 is installed, the compressed air generated by the air compressor CP passes through the after cooler 1 through the supply pipe P. After the moisture contained is removed, the air filter AF is supplied to the pneumatic equipment (AM) in the state of the secondary purification (removing fine foreign substances contained in the compressed air) is driven by the pneumatic equipment (AM).

이때, 에프터 쿨러(1)에서 압축공기의 수분이 제거되는 것은 통상적인 열교환 방식에 의한 것으로서, 압축공기가 메인 공급관(3)을 통해 분기관(2)으로 유입된 후, 구동모우터에 의해 회전되는 휀(F)과 분기관(2)에 형성된 방열핀(4)에 의해열교환이 이루어지면서 압축공기가 냉각되면서 응축현상에 의해 기체(수중기)상태로 압축공기에 포함된 수분이 결로현상을 일으키며 물방울(응축수)상태로 분기관(2)내에서 걸러지게 되어 압축공기에 포함된 수분이 제거 된다.At this time, the moisture of the compressed air is removed from the after cooler (1) by a conventional heat exchange method, and after the compressed air flows into the branch pipe (2) through the main supply pipe (3), it is rotated by a drive motor The heat exchange is performed by the heat radiation fins 4 formed in the fin (F) and the branch pipe (2) to cool the compressed air and condensation causes moisture contained in the compressed air in the gas (underwater) state, causing condensation. It is filtered in the branch pipe 2 in the form of water droplets (condensed water) to remove moisture contained in the compressed air.

이와 같이, 에프터 쿨러(1)에 의해 제거된 압축공기에 포함된 수분 즉, 응축수는 드레인 장치(10)에 의해 자동·배출되는 것으로서, 응축수 배출을 위한 드레인 장치(10)는 전기적인 신호에 의해 구동되는 솔레노이드(15)와 코일스프링(16)에 의해 볼 밸브(12)가 자동 개폐됨에 따라 별도의 수작업 없이 자동 배출이 가능한 것으로 이는 첨부 도면 도 3(a), (b)에 도시된 바와 같이, 일정시간 동안 에프터 쿨러(1)에 의해 압축공기에 포함된 수분이 제거되어 메인 공급관(3)에 일정량의 응축수가 고이게 되면, 제어부로부터 전기적인 신호가 솔레노이드(15)에 인가되어 로드(14)가 구동(후진이동)됨에 따라 이와 링크(17)로 연결된 개폐레버(13)가 회동되어 볼 밸브(12)가 개방된 상태[도 3(b)참조]를 이루게 되어 제거된 응축수가 배출되는 것이다.As described above, the water contained in the compressed air removed by the after cooler 1, that is, the condensate is automatically discharged by the drain device 10, and the drain device 10 for discharging the condensate is discharged by an electrical signal. As the ball valve 12 is automatically opened and closed by the driven solenoid 15 and the coil spring 16, it can be automatically discharged without a separate manual operation, as shown in FIGS. 3 (a) and (b). When the water contained in the compressed air is removed by the after cooler 1 for a predetermined time and a certain amount of condensed water is accumulated in the main supply pipe 3, an electrical signal from the controller is applied to the solenoid 15 so as to load 14. Is driven (reversely moved), the opening / closing lever 13 connected to the link 17 is rotated to form a state in which the ball valve 12 is opened (see FIG. 3 (b)), and the removed condensate is discharged. .

이상태에서, 일정시간이 경과하여 제어부로부터 전기적인 신호가 차단되어 솔레노이드(15)의 구동이 멈추게 되면, 개폐레버(13)의 타측단부에 결합된 코일스프링(16)의 반발력(솔레노이드의 로드 구동시 구동 거리에 해당하는 만큼 코일스프링 인장에 따른 탄발력)에 의해 개폐레버(13)가 로드(14)에 의한 구동(후진이동)시와는 반대방향으로 구동되어 볼 밸브(12)가 폐쇄(닫힘)되어 응축수 배출이 중단된다.In this state, when a predetermined time passes and the electric signal is cut off from the control unit and the driving of the solenoid 15 is stopped, the repulsive force of the coil spring 16 coupled to the other end of the opening / closing lever 13 (when driving the solenoid The opening / closing lever 13 is driven in the opposite direction as the driving (backward movement) by the rod 14 due to the elastic force according to the coil spring tension as much as the driving distance, so that the ball valve 12 is closed (closed). The discharge of condensate is stopped.

이와 같이하여, 에어 콤프레샤(CP)에서 생성된 압축공기를 냉각시킴과 동시에 이에 포함된 수분을 제거하여 응축수로 배출시킬 수 있는 것이다.In this way, it is possible to cool the compressed air generated by the air compressor (CP) and at the same time remove the moisture contained in it to be discharged to the condensate.

이와 같이, 본 발명에 따른 응축수 드레인 장치를 이용하여 에어 콤프레샤에서 생성된 압축공기의 압축열을 냉각시킬 수 있고, 또한 압축공기에 포함된 수중기 형태의 수분을 응축수화하여 제거·배출시킴에 있어, 응축수 배출이 자동으로 이루어짐에 따라, 수작업(응축수 배출을 위한 밸브개폐작업)에 의한 번거로움을 해소할 수 있을 뿐만 아니라, 수분에 의한 공압기기의 오동작을 예방할 수 있어 공압기기의 수명연장과 작업효율을 높일 수 있는 효과가 있다.As described above, the condensate drain apparatus according to the present invention can cool down the heat of compression of the compressed air generated by the air compressor, and also condensate and remove and discharge the water in the form of the submerged water contained in the compressed air. As the condensate is discharged automatically, it is possible to solve the trouble of manual operation (valve opening / closing operation for condensate discharge) and to prevent malfunction of the pneumatic equipment due to moisture. There is an effect that can increase the efficiency.
