Description

[Detailed explanation of the idea] The present invention relates to an oil combustion device.

More specifically, it relates to oil combustion equipment with a top and bottom wick type.

Recently, some oil combustion equipment with an upper and lower wick have adopted a configuration in which an automatic fire extinguishing device is used to rapidly lower the wick and extinguish the fire in the event of vibrations such as an earthquake.In this case, the space above the fuel tank is The vaporized fuel gas rose from the gap between the core frame and the empty cylinder, creating residual fire and delaying the extinguishing time.

The present invention has been developed in view of the above points, and is configured so that the fuel vaporized gas generated in the fuel tank when the core is lowered by an automatic fire extinguishing device is discharged to the outside of the oil combustion apparatus.

The present invention will be explained below with reference to the diagram. Oil combustion equipment main body 1
A combustor 4 is disposed within a frame 3 which is open at the front and disposed on a stand 2.

The combustor 4 has a so-called double tank structure, with an air cylinder 7 passing through a main tank 5 and an auxiliary tank 6, a combustion cylinder 8 disposed above the air cylinder, and a core frame 9 disposed outside the air cylinder 7. A core up-and-down device that allows the core body 10 located between the core body 10 to slide vertically, and is connected to the core up-and-down device, and when the main body 1 shakes due to an earthquake or the like, the core up and down device is activated to lower the core body 10. Consists of fire extinguishing equipment, etc.

The upper part of the auxiliary tank 6 bulges outward in diameter to form a fuel reservoir 11, and has a volume that can sufficiently store the fuel present in the auxiliary tank 6 when the main body 1 falls over, and the lower part of the core body 9 extends outward. It bulges out to form a fuel vaporized gas storage chamber 12, and an on-off valve 13 pivotally supported by a pin 35 is installed in the storage chamber at a proper position.
A pipe 14 having a tip positioned slightly upward is inserted through the pipe 14.

Further, a protector 16 having an opening 15 is fixed to the tip of the pipe 14 so as to surround the on-off valve 13 with a gap, and a protector 16 is attached to the outside of the protector with a gap surrounding the on-off valve 13. and a communication pipe 1 that penetrates the frame 3 and communicates with the outside air.
A covering body 18 connected to 7 is provided.

The combustion tube 8 has through holes 19, 19, 20, 20...
A wire mesh 24 is arranged on the large cylinder 23, and the space between the small cylinder 21 and the middle cylinder 22 is used as a combustor 25, and the core body 10 It is configured so that it is located at the top.

Further, the lead up/down device includes a knob 27 that rotates the lead up/down shaft 26.
The spring 28 and the claw 29 are wound around the core vertical shaft 26.
The structure is such that it works in conjunction with a fire extinguishing system that stores force in a gear 30 etc. that engages with the vibration sensor 31 and lowers the core body 10 using the return force of the spring 28 due to the swinging of the seismic sensor 31.

A horizontal reflector 32 is provided near the combustion tube 8, a reflector 33 is provided above it along the frame 3, and a heat shield 34 is provided around the outer periphery of the fuel vaporized gas storage chamber 12 of the core frame 9. It is.

The present invention is constructed as described above, and when the core body 10 is raised and combustion is performed for a long time, a certain amount of heat is shielded by the heat shield plate 34, but due to heat conduction by the core frame 9, etc., the main tank 5
The fuel in the auxiliary tank 6 is gasified, and the fuel reservoir 11. above the main tank 5 and in the auxiliary tank 6 is gasified. The gas storage chamber 12 is filled.

If the main body 1 shakes or falls due to an earthquake or the like, or the seismic sensor 31 is intentionally activated to disengage the pawl 29 and the gear 30, and the core body 10 is lowered by the restoring force of the spring 28, the auxiliary tank The volume of the space inside 6 becomes smaller due to the lowering of the core body 10, and since the gap between the core frame 9 and the core body 10 is extremely narrow, most of the pressure is applied to the opening/closing plate 13, and the tip of the pipe 14 opens. .

As a result, the fuel gas in the auxiliary tank 6 is guided to the outside of the main body 1 via the pipe 14, the opening 15, the covering 18, and the communication pipe 17.

As described above, according to the present invention, the fuel gas in the auxiliary tank is released to the outside of the main body when the core is lowered, so that it leaks from the extremely narrow gap between the core frame and the core and delays the extinction of the combustion flame. The fire is quickly extinguished as the core falls.

In other words, the inside of the combustion device's frame is heated by the combustion flame, so if the gas from the tank were to flow out into the flame, there would be no difference in temperature between the inside of the tank and the inside of the frame, so the gas would flow out poorly. However, in this invention, the gas flows out outside the frame, so the temperature outside the frame is much lower than the temperature inside the tank (i.e., the temperature inside the frame), so the gas flow ends instantly due to the temperature difference and the chimney effect of the pipe, and the fire can be quickly extinguished. It is done.

In addition, when the main body falls backward, since the stand 2 of the main body protrudes outward from the frame, it falls in an inclined state and a gap is created between the frame and the floor, and there is no problem with gas leakage.

Furthermore, in the case of a backward fall, the opening degree of the on-off valve increases due to its own weight, so that gas can flow out smoothly from the pipe.
