Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to the following technology: After the fuel supply operation to the fuel diffusion surface is stopped due to the extinguishment of vaporization combustion, the fuel remaining in the fuel supply pipe is dispersed in a high temperature state. This invention relates to a refueling device for a vaporizing burner, which prevents the oil from naturally leaking onto the surface and being evaporated and vaporized, and completely eliminates the dispersion of bad odor into the surrounding area when extinguishing vaporized combustion.

[Prior art] Conventionally, a horizontal rotating shaft is protruded from the base end of a horizontal combustion cylinder in which a gas chamber is installed, the distal end of the horizontal rotating shaft is closed, and the open base end is connected to the gas chamber. A horizontally cylindrical rotary vaporizer is attached and arranged so as to be freely rotatable, and the base end side of the horizontal combustion tube is connected to a blowing chamber that blows forced air into the rotary vaporizer, and the inner side of the tip of the rotary vaporizer is The surface is used as a fuel diffusion surface, and a fuel supply pipe with a fuel filler opening at the tip is inserted into the vaporizer, and the fuel supplied from the fuel filler port through the fuel diffusion surface to the circumferential surface of the rotary vaporizer is dispersed into a mist. The heating effect of the raw combustion flame evaporates and vaporizes the fuel supplied to the inner surface of the rotary vaporizer, and the generated vaporized gas is stirred and mixed with forced air to create an air mixture. A vaporizing burner capable of burning gas with more force than in a gas chamber is known, having been described in, for example, Japanese Patent Publication No. 59-50003 and Japanese Utility Model Application Publication No. 56-99216 prior to this application.

[Problems to be Solved by the Invention] Incidentally, in the conventional horizontal type vaporizing burner of this type, all of the oil supply pipes inserted into the rotary vaporizing body are provided above the horizontal rotation axis. Therefore, the tip of the fuel supply pipe is bent downward, and the fuel supply port opened at the tip necessarily opens downward at a position lower than the installation position of the fuel supply pipe inserted into the rotary carburetor. It had been. Therefore, even after the solenoid valve or oil supply pump is activated to stop fuel supply from the fuel supply pipe to the combustion diffusion surface when extinguishing vaporization combustion, the arrangement between the fuel supply pipe and the fuel inlet is Due to the differential head pressure caused by the difference in the height of the installation location, a small amount of fuel remaining in the fuel supply pipe naturally leaks from the end of the fuel filler port onto the hot fuel diffusion surface, and this evaporates on the fuel diffusion surface. The problem was that raw gas was generated and emitted into the surrounding area as a foul odor.

Therefore, in the present invention, when extinguishing vaporization combustion, even if the refueling operation from the fuel supply pipe to the fuel diffusion surface is stopped, a small amount of fuel remaining in the fuel supply pipe will naturally flow from the fuel supply port end onto the fuel diffusion surface. To provide a refueling device for a vaporizing burner, which can surely prevent the gas from leaking and falling, and can completely eliminate the dispersion of bad odor caused by raw gas generated when extinguishing vaporized combustion into the surrounding area.

[Means for Solving the Problems] Therefore, the technical problem of the present invention is to completely prevent a small amount of fuel remaining in the fuel supply pipe from spontaneously leaking and falling onto the fuel diffusion surface when vaporization combustion is extinguished. It's about getting used to it.

In the present invention, a horizontal cylinder is provided with a horizontal rotation shaft protruding from the base end of the horizontal combustion cylinder having a gas chamber therein, a distal end closed to the horizontal rotation shaft, and an open base end connected to the gas chamber. A rotary vaporizer is attached and arranged so as to be freely rotatable, and the base end side of the horizontal combustion tube is connected to a blowing chamber that blows forced air into the rotary vaporizer, and the inside tip of the rotary vaporizer has its surface covered with fuel. In the case where the fuel supply pipe has a diffusion surface, a fuel supply pipe is inserted into the rotary vaporizing body from a position lower than the horizontal rotation axis toward the fuel diffusion surface, and the tip side thereof is inclined upward toward the fuel diffusion surface, and the fuel supply pipe is connected to the fuel supply port. This is a refueling device for a vaporizing burner characterized by having an opening close to a fuel oil diffusion surface.

[Function] Now, when starting the burner, if the rotary vaporizer 6 is rotated at high speed, forced air is blown into the rotary vaporizer 6 from the ventilation chamber 9, and fuel is supplied from the oil supply pipe 20, the fuel will be The fuel is supplied to the fuel diffuser 19 which is rotating at high speed, and is diffused into the rotating vaporizer 6.
The mixture is further mixed with the forced air blown from the blower tube 9 in the rotary vaporizer 6 to become fine particles, and then ejected into the horizontal combustion tube 1 from the open peripheral end of the rotary vaporizer 6. Therefore, if it is ignited, raw combustion will occur within the horizontal combustion tube 1.

Then, when raw combustion occurs in the horizontal combustion tube 1,
Since the rotary vaporizer 6 is rapidly heated by the combustion flame, the fuel sprayed inside the rotary vaporizer 6 evaporates and becomes vaporized gas, which is further mixed with the forced air blown from the ventilation chamber 9. The mixed gas becomes a mixed gas, and after being pressurized into the gas chamber 4, it is ejected under a constant pressure state, and vaporization combustion occurs in the horizontal combustion tube 1. Once the state shifts to vaporization combustion, the rotary vaporization body 6 continues to be heated to a high temperature at all times, so vaporization combustion continues in the horizontal combustion tube 1.

Further, when extinguishing the vaporization combustion, the forced air blowing action and the rotation action of the rotary vaporizer 6 are continued as they are, or the fuel supply operation from the fuel supply pipe 20 is stopped while they are stopped. If so, no fuel is supplied from the fuel filler port 21 onto the fuel oil diffusion surface 19, so that vaporization combustion is automatically extinguished.

By the way, when extinguishing the vaporization combustion mentioned above,
Since the height of the refueling port 21 opened at the tip side of the refueling pipe 20 is higher than the installation position of the refueling pipe 20 inserted into the rotary vaporizer 6,
The fuel remaining in the fuel supply pipe 20 will not spontaneously leak and fall from the fuel filler port 21 onto the fuel diffusion surface 19 due to the head pressure, and the fuel supply operation can be stopped instantly when the fuel supply operation is performed. As a result, after the vaporization combustion is extinguished, it is possible to prevent the foul odor from being dissipated into the surrounding area due to the generation of raw gas caused by the fuel leaking and falling onto the high-temperature fuel diffusion surface 19 for any length of time. Evaporative combustion can be extinguished without producing a bad odor.

[Embodiments] The present invention will be described with reference to preferred embodiments shown in the accompanying drawings.

In the drawings, reference numeral 1 denotes a horizontal combustion tube with an open tip and a closed base end. The disk 2 and the outer cylinder 3 are sealed at their open ends to form a gas chamber 4 therebetween. A large number of flame holes 5 are bored in the circumferential surface of the combustion disk 2.
Reference numeral 6 denotes a horizontally cylindrical rotary vaporizer whose tip end is closed and whose base end is open. The base end side of the rotary vaporizer 6 is connected to the gas chamber 4 through an air mixture passage 8 formed at the base end of the combustion disk 2 and the outer cylinder 3. is communicated with. Further, a blowing chamber 9 is connected to the base end side of the horizontal combustion tube 1, and a blowing tube 10 is deeply inserted into the rotary vaporizer 6 from the blowing chamber 9. This blower tube 10 is integrally formed in a protruding manner with the outer tube 3 of the horizontal combustion tube 1, but for convenience, the blower tube 10 is molded separately from the outer tube 3 and then integrated with the outer tube 3. A combined configuration may also be used. A fuel splashing end 11 is formed at the open base end of the rotary vaporizer 6 and extends outward.
Further, a fuel scattering annular body 12 is attached to this portion, and a fuel spraying gap 13 is formed between the fuel scattering end 11 and the fuel scattering annular body 12. A fume chamber 15 is formed at the base end of the horizontal combustion tube 1 with a rotation gap 14 between it and the rotary vaporizer 6. It is communicated with the ventilation chamber 9.

Therefore, the wind blown from the blowing chamber 9 to the fumarole chamber 15 through the vent pipe 16 exits into the rotation gap 14 from the fume port 17 opened in the fume chamber 15, and flows through the horizontal combustion tube 1.
Fumes are emitted inside. 18 is a fuel diffuser,
The fuel oil diffuser 18 is removably mounted inside the tip of the rotary vaporizer 6 via a horizontal rotating shaft 7, and the surface of the fuel oil diffuser 18 is attached to the inner tip of the rotary vaporizer 6.
It is formed on the fuel oil diffusion surface 19 connected to the inner peripheral surface. Reference numeral 20 denotes a fuel supply pipe inserted into the rotary vaporizer 6 from a position lower than the horizontal rotating shaft 7. The tip side of the fuel supply pipe 20 is inclined upward toward the fuel diffusion surface 19, and the fuel supply pipe 20 has an opening at its tip. The port 21 is located close to the fuel oil diffusion surface 19.

Therefore, the oil supply port 21 is opened at a position higher than the position where the oil supply pipe 20 inserted into the rotary vaporizer 6 is disposed. This means that the fuel supply port 21 is opened at the distal end portion of the fuel supply pipe 20 that is curved diagonally upward. If the fuel filler port 21 is opened in this way, when the fuel supply is stopped to extinguish vaporization combustion,
The fuel remaining in the fuel supply pipe 20 naturally leaks and falls from the air supply port 21 onto the fuel diffusion surface 19 due to the head pressure difference, generating raw gas, which prevents foul odors from dispersing around.

[Effects of the Invention] In short, since the present invention has the above-mentioned technical means and effects, even if the horizontal rotation shaft 7 is inserted into the horizontal combustion tube 1 in which the gas chamber 4 is installed from the base end side. A horizontally cylindrical rotary vaporizer 6 is rotatably disposed with its tip protruding from the horizontal rotating shaft 7, its tip closed, and its base end open side connected to the gas chamber 4, and the base end of the horizontal combustion tube 1 is The rotary vaporizer 6 is connected to a blowing chamber 9 that blows forced air into the rotary vaporizer 6, and the inner surface of the tip side of the rotary vaporizer 6 is a fuel diffusion surface 19'. A fuel supply pipe 20 is inserted toward the fuel diffusion surface 19 from a position lower than the shaft 7, and its tip side is inclined upward toward the fuel diffusion surface 19, and its fuel supply port 21 is opened close to the fuel diffusion surface 19. Even when the supplied fuel is atomized and dispersed, and mixed gas is generated by evaporating the fuel and mixing with forced air to continue vaporization combustion, the fuel filler port 21 Since the installation position was higher than that of the fuel supply pipes 20 and 20' inserted into the rotary vaporizer 6, when the fuel supply pipe 20 is stopped when the vaporization combustion is extinguished, the fuel is supplied to the fuel supply pipe 20. The fuel naturally leaks from the opening 21 onto the extremely hot fuel diffusion surface 19 and generates raw gas, which prevents any foul odor from being dissipated to the surrounding area, creating a situation free of foul odors at all times. It has the effect of extinguishing a fire.
