Problems solved by technology
However, the heated fuel oil is prone to convection in the fuel oil storage tank
As a result, the temperature distribution of the fuel in the fuel oil storage tank becomes uneven, and when the temperature of the fuel oil at the extraction position is still low, the transfer efficiency deteriorates due to the high viscosity of the fuel oil
In order to prevent the transfer efficiency from deteriorating, it is necessary to install a heat source in a large area, which becomes a cause of cost increase

Embodiment Construction
[0023] Hereinafter, specific embodiments of the present invention will be described.
[0024] figure 1 It is a figure which shows the structure of the fuel oil transfer apparatus 1 which concerns on embodiment of this invention.
[0025] The fuel oil transfer device 1 includes a fuel oil settling tank 3 and a fuel oil daily tank 4 that communicate with a fuel oil storage tank 2 .
[0026] The fuel oil settling tank 3 is a tank for heating fuel oil, and the fuel oil is heated to a temperature of 70 to 80°C as an example by a heater not shown.
[0027] The fuel oil storage tank 2 and the fuel oil settling tank 3 are connected through a transfer pipe 5 , and a transfer pump 6 , a temperature sensor 7 and a pressure sensor 8 are arranged in the middle.
[0028] The temperature sensor 7 measures, for example, the temperature on the fuel oil inlet side of the transfer pump 6 .
[0029] The pressure sensor 8 is provided to monitor the pressure change of the fuel oil sucked into th...

The present invention provides a fuel oil transfer device capable of preventing fuel oil taken out from a fuel oil storage tank from being in a state of increased viscosity due to the influence of atmospheric temperature, thereby preventing deterioration of transfer efficiency. A fuel oil transfer device comprising: a fuel oil storage tank (2) installed at a position receiving heat from the atmosphere; and a fuel oil settling tank (3) for heating fuel oil sucked from the fuel oil storage tank (2) , and in order to return the heated fuel oil to the fuel oil storage tank (2), the fuel oil daily tank (4) temporarily stores the heated fuel oil, so that the fuel oil can be circulated, wherein the fuel oil storage tank ( 2) Equipped with: a suction pipe (2C) having a bell mouth (2B) opening toward the bottom at the deepest position in the longitudinal direction; and steam heating pipes (30) provided in pairs near the bell mouth (2B).
Description
technical field [0001] The present invention relates to a fuel oil transfer device, and more specifically, to a fuel oil storage tank for storing fuel oil supplied to an internal combustion engine or the like. Background technique [0002] Fuel oil used in boilers such as ships and generators is stored in storage units such as tanks, and is supplied to internal combustion engines and the like for consumption. [0003] As a storage unit for fuel oil used in ships, for example, in the case of a cargo ship, tanks arranged on a part of the double bottom provided on the lower side of the cargo hold are used. [0004] However, at this position, if a part of the double bottom is damaged due to grounding or the like, fuel oil may flow out from the fuel oil storage part. [0005] Therefore, it is proposed to secure a space for the fuel oil storage tank not at the bottom of the hull, but at a position higher than the bottom such as a corner near the upper deck (for example, Patent Do...
