Description of the invention [Technical field to which the invention belongs] The present invention relates to fuel oil in fuel storage tanks of ships and the like, and more specifically, it relates to flowing down the fuel heated by the sedimentation tank from the sedimentation tank or oil supply tank- The storage tank mixes a heating method for heating the fuel in the tank to a predetermined temperature, and in particular, it relates to a fuel heating method in a fuel storage tank that can partially enhance the heating effect of the fuel in the tank. [Previous technology] In ships, etc., when fuel is supplied to the engine, the fuel is usually transferred from the fuel storage tank to the fuel sedimentation tank through a transfer pipe through a transfer pipe. After heating the fuel, the fuel is passed through the fuel supply tank (the fuel is small). Out of the tank) and fuel purifier. At this time, the fuel in the fuel storage tank must be heated in order to make it low in viscosity and easy to transport. This kind of heating equipment is known in the past as a fuel storage tank 1 as shown in FIG. 8; a fuel sedimentation tank 3 equipped with a heating device (not shown) connected via a transfer pipe 2; The fuel pump in the fuel storage tank 1 is sent to the fuel pump 4 for the fuel settling tank 3; the fuel supply tank 5 connected to the fuel settling tank 3 "; either one of the fuel settling tank 3 and the fuel supply tank 5 'or both A suction pipe 6 of the fuel storage tank 1; and a device provided in the suction pipe 6 to flow down any one of the fuel sedimentation tank 3 and the fuel supply tank 5 or the heated fuel to the downflow pump 7 of the fuel storage tank 1. In FIG. 8, 8 is a heater, 9 is a temperature sensor, and i 〇, 1 1, 1, 2, 1 3 are valves, respectively. -4- 200537019 (2) In the device shown in Figure 8 above, the fuel in the fuel sedimentation tank 3 is heated by a heating device (not shown), and then cleaned by a fuel purifier (not shown) and sent to the fuel supply. The oil tank 5 is distributed and supplied to the main engine, auxiliary equipment, boiler, and the like. At the same time, a part of this heated fuel flows down through the suction main pipe 14 in the tank 1 to the fuel storage tank 1 by the action of the down-flow pump 7-, and the fuel in the tank 1 is warmed. In the device of FIG. 8 described above, a part of the heated oil is returned from the fuel precipitation tank 3 to the fuel supply tank 5 to the fuel storage tank 1 when the fuel in the tank 1 is heated. The flow rate and temperature must change according to the length of the suction pipe 6 or the conveying pipe 2, or the temperature change of seawater or outside air, and the size of the fuel storage tank 1. That is, when the heat of the reflowed fuel is more than the optimal amount, the heat radiation to the seawater or the outside air is increased, and when there is less, the predetermined amount of fuel cannot be delivered. Therefore, it is necessary to maintain the reflow heating optimally The amount and temperature of the fuel. Φ However, in the device of FIG. 8 described above, the temperature of the heated fuel returned to the fuel storage tank 1 through the suction main pipe 14 is high and the specific gravity is relatively low. Therefore, it rises immediately above the tank 1 or diffuses into the entire storage tank 1. Make it plus-hot. Therefore, a high-viscosity cold-warm oil state is maintained around the suction main pipe 14, and a poor suction from the suction main pipe 14 results in a poor thermal efficiency. In particular, as shown in FIG. 1 and FIG. 2, a water tank with a triple bottom is constituted by installing a water balance tank 16 6 ′ on the bottom 15 and a fuel storage tank 1 and a cargo layer 17 on the bottom. A is as shown in the first figure. The fuel storage tank 1 is formed with an open and expanded shape without compartments. Therefore, the heated -5- 200537019 (3) oil will spread to the entire tank 1 immediately. Fuel heating is a means to solve this problem. In the past, there is a well-known device that erects a barrier in front of the suction pipe 14 in the storage tank 1 to prevent the fuel from spreading after heating (see Japanese Patent Application No. 200 1-1 5293 (Japanese Patent Application Laid-Open) 2002-3083 99)). However, in the case of this device, the effect on a high or even deep fuel tank is large, but a low and flat fuel tank requires a high construction cost. • [Patent Document 1] Japanese Patent Application No. 2002-198408 [Patent Document 2] Japanese Patent Application No. 2001-115294 (Japanese Patent Application Laid-Open No. 2002-308399 [Summary of the Invention] [Problems to be Solved by the Invention] Here, the problem of the present invention is to provide When the heated fuel flows from the sedimentation tank or oil supply tank to the storage tank and is mixed to warm the fuel in the tank to a predetermined temperature of φ, the fuel heating efficiency in the fuel tank in the tank is partially improved, and the above-mentioned conventional technology is improved. There are disadvantages of the fuel storage tank. _ [Means for solving the problem] In order to solve the above-mentioned problem, according to the method for heating fuel oil in the fuel storage tank of the present invention, it is characterized by passing the heated fuel through the openings in the tank. In the heating method for mixing the fuel flowing down from the suction main pipe into the fuel storage tank to warm the fuel in the fuel storage tank, a partition wall is formed around the front end of the suction main pipe to form a box-shaped compartment in the storage tank. Heating-6-200537019 (4) Fuel flows into the box-type compartment through the front end of the suction main pipe to prevent the diffusion and heat dissipation of the heated fuel, and partially increases the heating of the fuel Since the present invention described above surrounds the front edge of the suction main pipe with a baffle plate and positions the front end in a small compartment of the 鄕 type, the heated fuel flowing into the fuel through the front end can prevent diffusion and heat dissipation, and effectively reduce the size of the box. The fuel in the compartment is heated to form a low viscosity and can be easily transported. Φ [Embodiment] Hereinafter, the present invention will be described in detail using the attached drawings.

Main machine, auxiliary machine, boiler, etc. At the same time, a part of the heated fuel is flowed down to the fuel storage tank 1 through the suction main pipe 14 in the tank 1 by the action of the down pump 7 to warm the fuel in the tank 1. The feature of the present invention is that, as shown in FIG. 3, the front end 18 of the suction main pipe 14 provided in the tank 1 is surrounded by a partition plate 19 in a direction that crosses the fuel storage tank 1, and there is fuel storage. A small box-shaped compartment 20 is formed in the groove 1. Thereby, the front end 18 is arranged in the box-shaped cubicle 20. In FIG. 3, the upper side of the partition plate 19 is preferably provided with a plurality of exhaust holes 21, and the lower side is preferably provided with a plurality of oil passage holes 22. In addition, the hole 23 is a relatively large hole, and is a hole for passing oil to a person.
