연료유 이송장치{AN APPARATUS FOR TRANSPORTING FUEL OIL}Fuel oil transfer device {AN APPARATUS FOR TRANSPORTING FUEL OIL}

본 발명은 선박, 발전기 등의 보일러(이하, 「선박 등」이라 함.)의 연료유 이송장치에 관한 것이고, 특히 연료유 세틀링(settling) 탱크 및/또는 연료유 서비스 탱크 중의 가열된 연료유의 정지 중의 자연유하(自然流下) 내지는 역류를 방지하는 연료유 이송장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel oil transfer device for a boiler (hereinafter referred to as a "ship", etc.) of a ship, a generator, and the like, in particular, for a heated fuel oil in a fuel oil settling tank and / or a fuel oil service tank. The present invention relates to a fuel oil feeder that prevents natural oil dropping or backflow during stoppage.

선박 등에서 연료유를 기관에 공급할 때에, 통상, 우선, 연료유를 연료유 저장탱크로부터 이송펌프에 의해서 이송관을 통과하여 연료유 세틀링 탱크로 보내고, 다음으로, 이 연료유 세틀링 탱크로부터 연료유 서비스 탱크(연료유 소출(小出)탱크)로 보내며, 여기로부터 연료유를 기관에 공급하고 있다. 이 때, 연료유 저장탱크 중의 연료유는 점도를 낮게 하여 이송하기 쉽게 하기 위해서 가온(加溫)되는 것이 필요하다.When supplying fuel oil to an engine from a ship or the like, usually, the fuel oil is first sent from the fuel oil storage tank to the fuel oil settling tank by a transfer pump, and then the fuel oil is set from the fuel oil settling tank. It is sent to an oil service tank (fuel oil output tank), from which fuel oil is supplied to the engine. At this time, the fuel oil in the fuel oil storage tank needs to be warmed in order to lower the viscosity and to facilitate transport.

이런 종류의 가온설비를 가지는 연료유 이송장치로서, 종래, 도 1에서의 밸브(15)를 구비하지 않는 장치, 즉, 연료유 저장탱크(1)와, 이것과 이송관(2)을 통하여 연통된 도시하지 않은 가열장치를 구비한 연료유 세틀링 탱크(3)와, 연료유 저장탱크(1) 중의 연료유를 연료유 세틀링 탱크(3)에 이송하기 위한 이송펌프(4)와, 연료유 세틀링 탱크(3)에 연통된 연료유 서비스 탱크(5)와, 연료유 세틀링 탱크(3) 및 연료유 서비스 탱크(5) 중 어느 한쪽 또는 양쪽을 연료유 저장탱크(1)에 연통하는 흡입관(6)과, 흡입관(6)에 설치되고, 연료유 세틀링 탱크(3) 및 연료유 서비스 탱크(5) 중 어느 한쪽 또는 양쪽 중의 가열된 연료유를 연료유 저장탱크(1)에 흘러내리게 하는 유하펌프(7)를 구비한 장치가 알려져 있다. 도 1에서 8은 히터, 9는 온도센서, 10, 11, 12, 13은 밸브이다.A fuel oil feeder having this kind of heating equipment, which is conventionally not provided with the valve 15 in FIG. 1, that is, communicates with the fuel oil storage tank 1 through this and the transfer pipe 2. A fuel oil settling tank 3 having a heating device (not shown), a transfer pump 4 for transferring the fuel oil in the fuel oil storage tank 1 to the fuel oil settling tank 3, and a fuel; The fuel oil service tank 5 communicated with the oil settling tank 3, and either or both of the fuel oil settling tank 3 and the fuel oil service tank 5 communicate with the fuel oil storage tank 1. And the heated fuel oil in any one or both of the fuel oil settling tank 3 and the fuel oil service tank 5 is installed in the fuel oil storage tank 1. A device having a falling pump 7 for flowing down is known. 1, 8 is a heater, 9 is a temperature sensor, and 10, 11, 12, and 13 are valves.

상술의 밸브(15)를 가지지 않는 도 1의 장치에서는 연료유 세틀링 탱크(3) 중의 연료유는 도시하지 않은 가열장치에 의해 가열되고, 다음으로, 도시하지 않은 연료유 청정기(淸淨機)에서 청정되어 연료유 서비스 탱크(5)로 이송되며, 여기로부터 도시하지 않은 주기(主機), 보기(補機), 보일러 등으로 분배 공급된다. 동시에 이 가열된 연료유의 일부는 유하펌프(7)의 작동에 의해 연료유 저장탱크(1)에 이 탱크(1) 중의 흡입주관(14)을 통하여 흘려내려, 이 탱크(1) 중의 연료유를 가온한다.In the apparatus of FIG. 1 which does not have the above-mentioned valve 15, the fuel oil in the fuel oil settling tank 3 is heated by the heating apparatus which is not shown in figure, Next, the fuel oil purifier which is not shown in figure Is cleaned and transported to the fuel oil service tank 5 from which it is distributed and supplied to a main machine, bogie, boiler, and the like not shown. At the same time, a part of the heated fuel oil flows into the fuel oil storage tank 1 through the suction main pipe 14 of the tank 1 by the operation of the lower pump 7 to discharge the fuel oil in the tank 1. Warm.

상술의 밸브(15)를 가지지 않는 도 1의 장치에서 가열된 연료유의 일부를 연료유 세틀링 탱크(3) 내지는 연료유 서비스 탱크(5)로부터 연료유 저장탱크(1)로 되돌리고, 이 탱크(1) 중의 연료유를 가온할 때, 이 되돌림 양 및 온도는 흡입관(6)이나 이송관(2)의 길이 혹은 해수(海水)나 외기의 온도변화에 대응하여 변화시킬 필요가 있다.A portion of the fuel oil heated in the apparatus of FIG. 1 without the above-described valve 15 is returned from the fuel oil settling tank 3 or the fuel oil service tank 5 to the fuel oil storage tank 1, and this tank ( When warming up the fuel oil in 1), this return amount and temperature need to be changed in correspondence with the length of the suction pipe 6 or the transfer pipe 2 or the temperature change of sea water or the outside air.

즉, 되돌려지는 가열된 연료유의 열량이 적정값보다 많은 경우에는 해수나 외기로의 열량의 방열이 많아지고, 적은 경우에는 소요량의 연료유의 이송을 할 수 없게 되며, 이 때문에, 되돌려지는 가열된 연료유의 양과 온도를 적정하게 유지할 필요가 있다.In other words, when the amount of heat of the heated fuel oil returned is greater than an appropriate value, heat dissipation of the amount of heat to seawater or outside air is increased, and when it is small, transfer of the required amount of fuel oil becomes impossible, and therefore, the heated fuel returned It is necessary to keep the amount and temperature of oil appropriately.

그러나, 상술의 밸브(15)를 구비하지 않는 도 1의 장치에서는 세틀링 탱크 및/또는 서비스 탱크 중의 가열된 연료유의 일부를 연료유 저장탱크로 흘러내리게 할 때에 연료유는 연료유 저장탱크로 돌아오지 않고 이송관 방향으로 역류해 버린다. 또, 연료유 저장탱크로부터의 연료유를 이송관 방향으로 보낼 때에 공기방울이 발생해 버린다.However, in the apparatus of FIG. 1 without the above-described valve 15, the fuel oil returns to the fuel oil storage tank when a portion of the heated fuel oil in the settling tank and / or the service tank flows down into the fuel oil storage tank. It does not come and flows back to the feed pipe direction. Moreover, air bubbles generate | occur | produce when sending the fuel oil from a fuel oil storage tank to a conveying pipe direction.

또한, 상술의 밸브(15)를 이송관(2)에만 밖에 구비하지 않는 도 1의 장치도 알려져 있다.(일본국 특허 제3807597호)Moreover, the apparatus of FIG. 1 in which only the above-mentioned valve 15 is provided only in the feed pipe 2 is also known. (Japanese Patent No. 3807597)

이 연료유 이송장치는 정지 중에서도 입구 측(흡입 측)의 압력이 높고, 출구 측(토출 측)의 압력이 낮은 경우가 대부분이다. 이것은 연료유 세틀링 탱크(펌프의 흡입 측)가 연료유 저장탱크(펌프의 토출 측)보다 높은 것에 의한다. 따라서, 장치의 정지 중에서도 이 압력에 의해 의도하지 않게 세틀링 탱크 및/또는 서비스 탱크로부터 저장탱크로 자연히 기름이 흐르게 된다.This fuel oil transfer device is most often at a high pressure on the inlet side (suction side) and a low pressure on the outlet side (discharge side) even during stop. This is because the fuel oil settling tank (the suction side of the pump) is higher than the fuel oil storage tank (the discharge side of the pump). Thus, even during shutdown of the device, this pressure causes the oil to flow naturally from the settling tank and / or the service tank into the storage tank.

그리고, 상술의 본 발명의 장치에 있어서, 개량의 주(主)포인트는 이송관(2)의 이송펌프(4)보다도 하류 측에 스프링(16)을 유지한 밸브(15)를 설치하고, 또한, 흡입관(6)의 유하펌프(7)보다도 하류 측에도 스프링(16)을 유지한 밸브(15)를 설치한 것에 있으며, 이것에 의해 세틀링 탱크(3) 및/또는 서비스 탱크(5) 중의 가열된 연료유를 이송관(2)의 방향으로 역류시키지 않고, 또한, 상기 세틀링 탱크(3) 및/또는 서비스 탱크(5) 중의 가열된 연료유를 흡입관(6)으로 흘러내리게 하지 않으며, 자연유하를 방지하면서, 상기 저장탱크(1)로 흘러내리게 하도록 한 것을 특징으로 한다.In the apparatus of the present invention described above, the main point of improvement is provided with a valve 15 which holds the spring 16 on the downstream side of the transfer pump 4 of the transfer pipe 2, The valve 15 which holds the spring 16 in the downstream of the flow-pump 7 of the suction pipe 6 is provided, and is heated by the settling tank 3 and / or the service tank 5 by this. Does not flow back the fuel oil in the direction of the transfer pipe 2, and does not cause the heated fuel oil in the settling tank 3 and / or the service tank 5 to flow into the suction pipe 6, It is characterized in that the flow to the storage tank (1) while preventing the falling.

도 2는 밸브(15)가 닫힌 상태, 도 3은 열린 상태의 단면도이며, 운전휴지 중은 도 2에 나타내는 바와 같이, 핸들(18)을 닫아 밸브누름부(21)를 밸브자리(22)에 맞닿게 한다. 이 상태에서는 입구(19)로부터의 연료유는 출구(20)로 진행하지 않는다.2 is a cross-sectional view of a state in which the valve 15 is closed, and FIG. 3 is an open state. As shown in FIG. 2 during operation stop, the handle 18 is closed to close the valve pressing portion 21 to the valve seat 22. Make contact. In this state, the fuel oil from the inlet 19 does not proceed to the outlet 20.

운전 중, 통상은 도 3에 나타내는 바와 같이 핸들(18)을 열고, 밸브봉(23)을 위쪽으로 올린 상태로 해 둔다. 이 상태에서도, 통상은 스프링(16)의 가압력에 의해서 밸브누름부(21)가 와셔(17)를 통하여 밸브자리(22)에 가압된다. 이 때문에 밸브누름부(21)는 밸브자리(22)에 맞닿고 있으며, 입구(19)로부터의 연료유는 밸브누름부(21)로 저지되어 출구(20)로는 통하지 않는다. 따라서, 가열된 연료유가 이송관(2)의 방향으로 역류되는 것은 방지되며, 또한, 가열된 연료유가 흡입관(6)의 방향으로 자연유하되는 것도 방지된다. 동시에, 연료유 저장탱크(1)로부터 흡입주관(14)을 거쳐 발생한 공기방울도 부숴져 없어져 버린다.During operation, normally, as shown in FIG. 3, the handle 18 is opened and the valve rod 23 is raised upward. Even in this state, normally, the valve pressing portion 21 is pressed to the valve seat 22 via the washer 17 by the pressing force of the spring 16. For this reason, the valve press part 21 is in contact with the valve seat 22, and the fuel oil from the inlet 19 is blocked by the valve press part 21, and it does not go to the outlet 20. As shown in FIG. Therefore, the heated fuel oil is prevented from flowing back in the direction of the feed pipe 2, and the heated fuel oil is also prevented from naturally falling in the direction of the suction pipe 6. At the same time, air bubbles generated from the fuel oil storage tank 1 via the suction pipe 14 are also broken down.

스프링(16)은 임의의 압력, 예를 들면 약0.098MPa. 1.0Kgf/㎠(전개(全開)시)로 설정할 수 있다. 이것에 의해, 연료유 저장탱크(1)로부터의 가열된 연료유는 입구(19)로부터 밸브누름부(21)를 밀어 올려 출구(20) 방향으로 흐른다. 이 때, 공기에서 발생한 거품도 압력에 의해 소거(消去)한다.The spring 16 may be at any pressure, for example about 0.098 MPa. It can be set to 1.0 Kgf / cm 2 (when fully developed). Thereby, the heated fuel oil from the fuel oil storage tank 1 pushes the valve | bulb press part 21 from the inlet 19, and flows to the outlet 20 direction. At this time, bubbles generated in the air are also removed by the pressure.

본 발명에 관한 연료유 이송장치는 이송관(2)의 이송펌프(4) 및 흡입관(6)의 유하펌프(7)보다도 하류 측에 각각 스프링(16)을 유지한 밸브(15)를 설치했기 때문에, 세틀링 탱크(3) 및/또는 서비스 탱크(5) 중의 가열된 연료유를 이송관(2)으로 역류시키지 않고, 또한, 흡입관(6)에 자연유하시키지 않고 상기 저장탱크로 흘러내리게 하며, 또한, 이송관(2) 중의 공기방울도 자동적으로 부서져 없어져 버려, 산업상의 이용 가능성이 높다.In the fuel oil conveying apparatus according to the present invention, a valve 15 holding springs 16 is provided on the downstream side of the transfer pump 4 of the transfer pipe 2 and the lower pump 7 of the suction pipe 6, respectively. Thus, the heated fuel oil in the settling tank 3 and / or the service tank 5 is allowed to flow down into the storage tank without being flowed back into the transfer pipe 2 and without a natural drop in the suction pipe 6. In addition, air bubbles in the transfer pipe 2 are also automatically broken down, and industrial applicability is high.
