본 발명에서 제공하는 유압유닛용 오일탱크(1)는 오일을 저장하는 상부 개방형 저유조(2)를 구성하고, 저유조(2)의 개방된 상측으로는 덮개(3)를 덮어 저유조(2)를 밀폐한다. 이때 저유조(2)와 덮개(3)의 사이에는 누유를 방지할 수 있도록 패킹(4)을 개재하며, 볼트와 너트의 조합으로 구성되는 고정수단(5)에 의해 상호 결합되게 함으로 해서 덮개(3)를 임의로 탈착할 수 있게 한다. The oil tank 1 for an oil pressure unit according to the present invention constitutes an upper open low oil tank 2 for storing oil and a lid 3 is provided on the open upper side of the low oil tank 2, ). At this time, the packing 4 is interposed between the low oil tank 2 and the lid 3 so as to prevent leakage, and they are coupled to each other by the fixing means 5 composed of a combination of bolts and nuts, 3) can be arbitrarily detached.

상기 저유조(2)에는 유면계(6)를 설치하여 저유량을 육안으로 쉽게 확인할 수 있게 한다.An oil level meter (6) is installed in the low oil tank (2), so that a low flow rate can be visually confirmed easily.

상기 덮개(3)의 상부에는 유압펌프(7)가 설치되며, 유압펌프(7)와 연결되며 저유조(2)에 집유되어 있는 오일에 단부가 침지되는 공급관(8)과 함께 사용처를 경유한 오일을 저유조(2)로 회수하는 회수관(9)을 각각 배관한다.A hydraulic pump 7 is provided at the upper portion of the lid 3 and is connected to a hydraulic pump 7 and is connected to a supply pipe 8 through which the end portion is immersed in oil contained in the low- And a return pipe 9 for collecting the oil into the low-temperature tank 2 are respectively piped.

상기 공급관(8)의 선단에는 오일에 침지 상태로 있도록 석션필터(10)를 교환 가능하도록 나사 조립한다.At the tip of the supply pipe (8), the suction filter (10) is screwed so as to be replaceable so as to be immersed in the oil.

상기와 같은 구성의 유압유닛용 오일탱크(1)는 일반적으로 널리 사용되고 있는 구성이다.The oil tank 1 for the hydraulic unit having the above-described structure is a widely used construction.

본 발명은 상기와 같이 구성되는 유압유닛용 오일탱크(1)를 구성함에 있어서, 첫째 고압의 에어를 석션필터(10)의 역방향에서 제공하는 방법으로 석션필터(10)의 청소가 간편하게 이루어질 수 있게 하고, 둘째 오일에 침지 상태로 있는 쇳가루 제거수단(20) 설치하여 오일에 포함되는 쇳가루를 수시로 청소할 수 있도록 한다.The present invention provides an oil tank (1) for a hydraulic unit as described above, wherein the first high pressure air is provided in a direction opposite to the suction filter (10) so that the suction filter (10) And secondly, the powder removal means 20, which is immersed in the oil, is installed so that the powder contained in the oil can be cleaned from time to time.

상기 석션필터(10) 청소를 하기 위한 구성으로는 도 4에 도시된 바와 같이 공급관(8)에 T형 엘보(11)를 이용하여 고압의 에어가 공급되는 에어주입관(12)을 배관연결하고, 오일탱크(1)에서 T형 엘보(11)를 지난 위치의 공급관(8)과 에어주입관(12)에 각각 오일차단용 밸브(13)와 에어차단용 밸브(14)를 설치하여 역방향으로 고압의 에어를 공급토록 함으로 해서 석션필터(10)를 수시로 청소할 수 있게 한다.As shown in FIG. 4, the suction filter 12 is connected to the supply pipe 8 by piping an air injection pipe 12 through which a high-pressure air is supplied by using a T-shaped elbow 11 , An oil shutoff valve 13 and an air shutoff valve 14 are provided in a supply pipe 8 and an air inflow pipe 12 at a position past the T-shaped elbow 11 in the oil tank 1, So that the suction filter 10 can be cleaned from time to time by supplying high-pressure air.

즉, 오일을 공급할 때에는 오일차단용 밸브(13)를 개방하고, 에어차단용 밸브(14)를 차단하며, 고압의 에어로 석션필터(10)를 청소코자 할 시에는 상기와는 반대로 오일차단용 밸브(13)를 차단하고, 에어차단용 밸브(14)를 개방한 상태에서 석션필터(10)에 역방향으로 고압의 에어를 공급한다.That is, when oil is supplied, the oil shutoff valve 13 is opened, the air shutoff valve 14 is shut off, and when the high-pressure air suction filter 10 is to be cleaned, Pressure air is supplied to the suction filter 10 in the reverse direction while the air shutoff valve 14 is opened.

이와 같이 고압의 에어를 공급할 경우 에어는 석션필터(10)의 망공을 통해 저유조(2) 내의 오일로 배출되는데, 이때 석션필터(10)에 달라붙어 망공을 차단하고 있는 쇳가루 등이 석션필터(10)에서 분리되어 오일에 혼입되는 것이다.When the high-pressure air is supplied, the air is discharged to the oil in the low-pressure tank 2 through the vents of the suction filter 10. At this time, the dust or the like which sticks to the suction filter 10 and blocks the vents, 10) and mixed in the oil.

그리고 상기 쇳가루 제거수단(20)의 설치는 덮개(3)에 돌출되도록 소재구(21)를 형성하고, 소재구(21)에는 분리 가능하게 소재용 뚜껑(22)을 결합한다.The material removing means 20 is provided with a material mouth 21 so as to protrude from the lid 3 and a material lid 22 is removably attached to the material mouth 21.

상기 소재용 뚜껑(22)에는 도 5에 도시된 바와 같이 쉽게 휘어지는 탄성봉(23)을 결합하고, 탄성봉(23)에는 쇳가루를 흡착할 수 있는 영구자석(24)을 결합한다.As shown in FIG. 5, the material lid 22 is coupled with an easily bending elastic rod 23, and the elastic rod 23 is coupled with a permanent magnet 24 capable of adsorbing flour.

상기 영구자석(24)은 링타입으로 구성된 것을 여러개 결합하며, 영구자석(24) 사이에는 비자성체로 구성된 간격유지 링(25)을 결합토록 한다.The permanent magnets 24 are coupled to a plurality of ring-type permanent magnets 24, and a gap retaining ring 25 made of a nonmagnetic material is coupled between the permanent magnets 24.

상기 탄성봉(23)은 오일에 침지된 상태에서 변형이 없는 탄소섬유(23a) 또는 코일스프링(23b) 중 하나 또는 둘을 조합한 것을 사용한다.The elastic rods 23 are made of a combination of one or both of the carbon fibers 23a and the coil springs 23b which are not deformed in a state immersed in oil.

또한 상기 탄성봉(23)은 저유조(2)의 높이보다 길게 형성하여 도 3에 도시된 바와 같이 오일에 침지된 상태에서 휘어지도록 한다.Further, the elastic bar 23 is formed to be longer than the height of the lower oil tank 2, and is bent in a state of being immersed in oil as shown in FIG.

상기와 같이 쇳가루 제거수단(20)을 구성할 경우 오일에 포함되는 쇳가루가 영구자석(24)에 달라붙게 되고 또 석션필터(10) 청소과정에서 오일에 혼입되는 쇳가루를 흡착시킬 수 있으며, 작업자가 소재용 뚜껑(22)을 분리하는 수고로움으로 영구자석(24)에 흡착된 쇳가루를 청소할 수 있게 되는 것이다.When the loose powder removing means 20 is constructed as described above, the loose powder contained in the oil adheres to the permanent magnet 24 and the loose powder mixed in the oil can be adsorbed during the cleaning process of the suction filter 10, The lump 22 for the material can be removed to clean the powder adsorbed on the permanent magnet 24. [

또한 본 발명의 쇳가루 제거수단(20)은 탄성봉(23)이 저유조(2)의 높이보다 길게 형성되므로 소재용 뚜껑(22)을 회전시킬 때 탄성봉(23)에 결합되는 영구자석이 저유조(2)의 바닥에서 원을 그리게 되므로 오일과의 접지면적이 많아져 쇳가루 흡착을 더욱 효과적으로 행할 수 있는 것이다.Since the elastic rod 23 is formed to be longer than the height of the low oil bath 2, the loose powder removing means 20 of the present invention can prevent the permanent magnets, which are coupled to the elastic rods 23 when the material lid 22 is rotated, Since a circle is drawn from the bottom of the oil tank 2, the ground contact area with the oil is increased, so that the flour can be more effectively adsorbed.

도면 중 미설명 부호 15는 회수관(9)에 설치되어 회수되는 오일을 냉각하는 오일쿨러를 도시한 것으로, 16은 유압펌프(7)를 구동하는 모터를 도시한 것이다.In the figure, reference numeral 15 denotes an oil cooler provided in the recovery pipe 9 for cooling the recovered oil, and 16 denotes a motor for driving the hydraulic pump 7.

본 발명의 상세한 설명에서는 구체적인 실시례에 관해 설명하고 있으나, 본 발명의 범주에서 벗어나지 않는 한도 내에서 다양한 변형이 가능함은 물론이다. 그러므로 본 발명의 보호 범위는 설명된 실시례에 국한되어 정해져서는 안 되며, 후술하는 청구범위 뿐만 아니라 균등한 것들에 의해 정해져야 한다.
