[Industrial application field]

This invention is a fuel tank for engines used outdoors, such as portable engine generators. Collect spilled fuel at the oil inlet to the tank, and remove moisture such as rainwater and fuel oil. This relates to a configuration for separating and selecting fuel oil and putting only fuel oil into the fuel tank.

0002

[Conventional technology]

The technology related to fuel tank overflow fuel recovery equipment has been known for some time. -ing For example, the technology described in Japanese Utility Model Application Publication No. 52-132918. be. Also, technology that configures an overflow fuel recovery device using membrane members for oil and water separation. Also, since the technology described in Japanese Patent Application Laid-Open No. 1-310161 is known, Ru.

[Problems that the idea should solve]

However, in the above conventional technology, the overflow fuel is guided through a pipe, etc. Valuable fuel was wasted as it was being discharged outside the aircraft, and the discharged fuel also ignited. There was a risk of it catching fire. Additionally, in the past, the discharged fuel oil was left in a puddle. The problem was that it spread to the surface and caused environmental pollution in the vicinity. The present invention aims to solve these problems of the prior art.

0004

[Means to solve the problem]

The purpose of this invention is to eliminate the above-mentioned problems, and it is constructed as follows. has been completed. That is, the glass fiber filter net 1 impregnated with tetrafluoroethylene resin is opened. -Provided in the bar flow passage 2, and made of tetrafluoroethylene resin to prevent overflow fuel. The water and fuel oil are separated by the difference in the water repellent angle, and the water is separated from the fuel oil through the overflow passage. 2, the fuel oil passes through the glass fiber filtration net 1, and is discharged from the auxiliary fuel tank 5. It is recovered into the main fuel tank 6.

[0005]

[Effect]

Next, the operation of the present invention will be explained. That is, the overflow fuel is converted into tetrafluoroethylene. It passes through a glass fiber filtration net 1 made of resin and is separated into water and fuel oil. However, moisture such as raindrops is removed by the glass fiber filtration net 1 due to the water repellent angle difference. 1, it reaches the drain passage 8 from the drain hole 7 and is discharged outside the aircraft. be done. Since the water repellency angle of fuel oil is smaller than that of water, the glass fiber filtration net 1 from the glass fiber filtration network 1 to the main fuel tank 6. They will be guided by the guide.

【Example】

Next, embodiments of the present invention will be described. Figure 1 shows the overflow fuel recovery device of this invention. 2 is a perspective view of an engine working machine equipped with a 3 is a front view, and FIG. 4 is a front sectional view. The engine working machine mentioned above is The engine E drives the generator D to generate electricity, and is used at construction sites and other places. It will be placed in other places where emergency power is required. As shown in Figure 4, the engine An engine E and a generator D are arranged inside the gin work machine. The engine E A radiator 18 for cooling is placed on the side, and is separated from the radiator 18. A muffler chamber in which a muffler 16 is arranged is configured with a wall separating the muffler chamber. Engine E An air cleaner 17 is installed horizontally in front of the. A battery is located in front of generator D. The main fuel tank is located above the generator D and the battery 15. 6 is placed. In the present invention, fuel is poured into the filler cap 10 of the main fuel tank 6. This eliminates the spillage of fuel oil that occurs when oiling.

[0007] As shown in Figures 1, 2, and 3, there is an opening/closing door for repair and inspection on the front of the engine working machine. 21.21 are provided. In addition, a muffler with a muffler 16 placed on the top surface. A cooling air outlet 20 is provided for blowing out the radiator cooling air from inside the room. Ru. Also, place the engine working machine at the center of gravity of the machine on the top plate 9, such as a crane or forklift. A lifting hook 22 is provided for lifting by a hand. Also suspended Two-point hanging hooks 13, 13 are also provided in case there are two points. The hanging Since the reinforcing formwork material is installed at the lifting hook 22, the reinforcing formwork material is The channel portion is used as the drain passage 8. In addition, the oil filler cap 10 is It is provided near the part of the drain passage 8 that the reinforcing formwork material constitutes, and the oil filler port The fuel oil spilled when filling the lid 10 is automatically filled into the main fuel tank 6. It is something to do.

[0008] Figure 5 shows a drain passage formed by reinforcing formwork in the top plate 9 of an engine working machine. 8 is a perspective view of part 8. FIG. Figure 6 shows a cross section of the drain passage 8 and the glass fiber filter net 1. The top view and FIG. 7 are similarly enlarged sectional views. As shown in FIG. 5, the lower surface of the upper plate 9 Then, fill the entire width of the top plate 9 with glass so as to cross the overflow passage 2. An auxiliary fuel tank 5 provided with a fiber filtration net 1 is provided. Also in Figure 6 As shown, a reinforcing construction material 11 is installed in the middle of the drain passage 8 made of reinforced formwork material. is constructed, and the top plate 9 is stretched over it, and the bridge portions 14 and 14 of the top plate 9 are Ru. Further, two-point hanging hooks 13, 13 are arranged at the front and rear positions. Lubrication cap 1 0, an overflow passage 2 is provided at a position one step lower than the top plate 9. The fuel oil spilled without being filled into the oil filler cap 10 is stored in the overflow passage. 2, passes through the glass fiber filtration net 1, enters the auxiliary fuel tank 5, and the auxiliary fuel From the take-out pipe 3 from the tank 5 and the inherited rubber hose 4, connect it to the tank pipe 12. It is contained within. If it rains again, rainwater collects on the overflow passage 2. In order to prevent this rainwater from being guided into the main fuel tank 6, A glass fiber filtration net 1 made of ethylene resin is configured to repel rainwater. -ing The rainwater flows along the drain passage 8 before and after the engine working machine. It is configured to flow in the direction.

[0009] As shown in FIGS. 6 and 7, an overflow passage 2 and an auxiliary fuel tank 5 are constructed. has been completed. That is, the overflow passage 2 is configured at a position one level lower than the top plate 9. and passes through the drain hole 7 at a position one step lower than the overflow passage 2. A drain passage 8 is provided through which rainwater flows. Also, overflow passage 2 and door An auxiliary fuel tank 5 is provided in a groove shape between the drain holes 7 and across the entire width of the top plate 9. The upper surface of the auxiliary fuel tank 5 is covered with glass at the height of the overflow passage 2. The fiber filtration network 1 is blocked. The inside of the glass fiber filtration net 1 is made of tetrafluoride. It is composed of ethylene resin, and the tetrafluoroethylene resin has different water repellent angles. This allows only fuel oil to pass through without water, separating rainwater and fuel oil. It is possible. Then, it passes through a glass fiber filtration net 1 to an auxiliary fuel tank 5. The fuel oil accumulated inside is transferred from the take-out pipe 3 to the tank pipe via the rubber hose 4. from the tank pipe 12 to the main fuel tank 6. I'm going.

[Effect of the idea]

Since the present invention is constructed as described above, it has the following effects. That is, , First, all the fuel oil spilled when filling oil from the oil filler cap 10 is covered with glass fibers. Since it passes through the filter net 1 and is collected from the auxiliary fuel tank 5 to the main fuel tank 6, This eliminates the risk of leaking outside the body and igniting it or polluting the environment. . Second, by keeping the auxiliary fuel tank 5 open to the air at all times, rain can be avoided. There is a risk that rainwater will be collected in the main fuel tank 6 if the auxiliary fuel tank A glass fiber filtration net 1 made of tetrafluoroethylene resin is interposed in the section 5. Therefore, rainwater cannot pass through the glass fiber filtration net 1 due to the difference in water repellency. , it can be discharged from the drain hole 7 through the drain passage 8 to the outside of the aircraft. Ru.
