Description of the invention [Technical field to which the invention pertains] The present invention relates to fuel in a fuel storage tank of a ship or the like, and more particularly to the flow of fuel heated by a sedimentation tank from a sedimentation tank or a supply tank m storage tank mixing method for heating the fuel in the tank to a predetermined temperature, in particular, a fuel heating method in a fuel storage tank that can partially enhance the heating effect of the fuel in the tank. [Prior Art] In ships and the like, when fuel is supplied to the engine, fuel is usually delivered from the fuel storage tank to the fuel sedimentation tank through the transfer pipe through the transfer pump, and after the fuel is heated, the fuel supply tank (fuel oil) Small out of the slot) and fuel. Cleaner and other supply engines. At this time, the fuel in the fuel storage tank must be heated in order to make it low in viscosity and easy to convey. Such a heating device is known in the prior art as a fuel storage tank 1 as shown in Fig. 8, and a fuel storage tank 3 having a heating device (not shown) that communicates via the conveying pipe 2; The fuel in the fuel storage tank 1 is sent to the transfer pump 4 for the fuel settling tank 3; the fuel supply tank 5 connected to the fuel settling tank 3'; one of the fuel settling tank 3 and the fuel supply tank 5 or both sides are connected to the fuel The suction pipe 6 of the storage tank 1 and the device provided in the suction pipe 6, and the fuel pumping tank 3 and the fuel oil supply tank 5, or both of the heated fuel, are discharged to the downflow pump 7 of the fuel storage tank. In Fig. 8, 8 is a heater, 9 is a temperature sensor, and 1 〇, 11, 12, and 13 are valves, respectively. -4- (2) 13〇1866 In the apparatus of Fig. 8 above, the fuel in the fuel settling tank 3 is heated by a heating device not shown in Fig. 2, and secondly by a fuel purifier (not shown). It is sent to the fuel supply tank 5, and is distributed to the main unit, the auxiliary machine, the boiler, and the like. At the same time, a part of this heated fuel is discharged to the fuel storage tank 1 through the suction main pipe 14 in the tank 1 by the action of the down pump 7, and the fuel in the tank 1 is warmed. In the apparatus of Fig. 8 above, when a portion of the heated oil is heated from the fuel solution tank 3 to the fuel supply tank 5 and returned to the fuel storage tank 1 to heat the fuel in the tank 1, the back The flow rate and temperature must be changed according to the length of the suction pipe 6 or the delivery pipe 2, or the temperature change of the seawater or the external air, and the size of the fuel storage tank 1. That is to say, when the heat of the reflowed fuel is more than the optimum amount, the heat dissipation of the sea water or the external air is increased, and when the amount of heat is small, the predetermined amount of fuel cannot be delivered. Therefore, it is necessary to maintain the optimum. The amount and temperature of the fuel heated under reflux. ® However, in the apparatus of Fig. 8 above, the temperature of the heated fuel returned to the fuel storage tank 1 by the suction main pipe 14 is relatively high in specific gravity, so that it immediately rises above the tank 1 or diffuses into the entire storage tank 1, Make it _ hot. Therefore, the periphery of the suction main pipe 14 maintains a high-temperature cold oil state, and the suction failure from the suction main pipe 14 is formed, and the thermal efficiency is poor. In particular, as shown in Figs. 1 and 2, a balance tank 16 for water is provided in the bottom 15 of the ship, a fuel storage tank 1 is provided thereon, and a triple bottom type ship A composed of a cargo layer 17 is provided thereon. As shown in Fig. 1, the fuel storage tank 1 is formed with an open-cell expansion without a compartment. Therefore, the heated fuel -5-(3) 1301866 oil immediately diffuses into the entire tank 1, and the fuel in the fuel storage tank 1 is added. The temperature is difficult. ^ A means for solving this problem, which is well known in the prior art is a device for erecting a barrier in front of the suction main pipe 1 in the storage tank 1 to prevent fuel from being diffused after heating (refer to Japanese Patent Application No. 2001 1 - 5293 (Special Edition 2002-) 3083 99 )). However, in the case of this device, the effect on the fuel tank of high or deep is large, but low and flat requires high construction cost. 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 The above-mentioned conventional knowledge is improved by mixing the heated fuel from the sedimentation tank or the oil supply tank to the storage tank and mixing the fuel in the tank to a predetermined temperature. 'The fuel heating efficiency in the fuel tank in the partial lifting tank' A fuel storage tank having the disadvantages of the technology. 黩^ [Means for Solving the Problem] In order to solve the above problems, the method for heating the fuel in the fuel storage tank according to the present invention is characterized in that the heated fuel is passed through the tank. a method of heating the fuel in the fuel storage tank by mixing the suction main pipe of the hole into the fuel storage tank, and forming a box type in the storage tank by surrounding the front end of the suction main pipe with a partition plate Between, heating -6- (4) 1301866 fuel flows through the front end of the suction main pipe into the diffusion and heat dissipation of the box type fuel, and the above-mentioned invention for partially lifting the fuel is separated by Surround suction, the front end is positioned in the small compartment of the 鄕 type, because the heated fuel can prevent diffusion and heat dissipation, and the fuel is heated to form a low viscosity and can be easily transported φ.
