Description

[Detailed description of the invention] This invention uses the inner and outer surfaces of the hollow diffusion cylinder to reliably send the fuel sent into the combustion reservoir in a diffused manner to the inner surface on the tip side of the vaporization cylinder. The present invention relates to an improvement in an oil feeding device for a vaporizing burner that can achieve very good combustion and vaporizing combustion under stable conditions.

Conventionally, a vaporizer tube with a closed tip and an open base end is directly connected to a rotating shaft inserted into a combustion tube, and a conical diffuser is closely attached to the inside of the tip of the vaporizer tube. A tapered oil feeding fitting is arranged on the outer periphery of the free end side of the diffuser, and the tip opening of the oil feeding pipe is connected to the oil feeding fitting, so that the fuel sent from the oil feeding pipe to the oil feeding fitting is connected to the oil feeding fitting. An oil feeding device for a vaporizing burner that can achieve a vaporizing combustion state rather than a main combustion state by sending oil along only the surface of the diffuser and in a diffused manner to the inner surface of the vaporizing cylinder was developed by the applicant of the present invention. It has been developed as shown in Japanese Patent No. 52-55721, and its implementation has brought about considerable effects.

By the way, in the oil feeding device for the vaporizing burner as described above, the fuel feeding action was performed only through the outer surface of the diffusion tube, so dust may adhere to the outer surface of the diffusion tube for some reason. If this occurs, the suction action may stop due to the deposits, or the suction may become unsmooth, resulting in a situation in which a certain amount of combustion cannot be uniformly distributed and supplied over the entire inner surface of the tip side of the vaporizer cylinder. As a result, the amount of moisture gas generated becomes unstable, resulting in the inconvenience that stable vaporization combustion cannot be continued for a long period of time, and there is a strong desire to improve this problem.

In view of the above, the present invention has been developed by disposing a hollow diffusion tube with a gap between the fumes and the inner and outer surfaces of the rotating vaporization tube as fuel suction and diffusion surfaces inside the tip of the rotating vaporization tube, and furthermore, on the free end side of the diffusion tube. In this case, a fuel reservoir cylinder is curved in a U-shaped cross section so that the free end side of the fuel suction and diffusion surface provided on the inner and outer surfaces of the diffusion tube is disposed in a non-rotating state, and one end of the oil pipe is connected to the fuel reservoir. By inserting an opening into the reservoir cylinder, even if either the inner or outer surface of the diffusion cylinder is dusty or rough, and the oil delivery operation becomes inaccurate, the fuel can be supplied into the reservoir cylinder. A vaporizer that reliably diffuses and transfers fuel to the inner surface of the vaporizer cylinder through the fuel suction and diffusion surfaces provided on the inner and outer surfaces of the diffusion cylinder, thereby not only generating live combustion but also allowing vaporization combustion to continue after a stable state. The present invention is intended to provide an oil feeding device for a burner, and the configuration of the device according to the present invention will be described below with reference to a preferred embodiment shown in the accompanying drawings.

In the drawing, 1 indicates a large number of gas ejection holes 4 on the surface.
It is a combustion cylinder in which a gas chamber 3 is formed by extending combustion disks 2 with perforated holes along the inner periphery at appropriate intervals, and an opening 5 is provided approximately in the center of the gas chamber 3. A vaporizing tube 6 with one side open and directly connected to a rotating shaft 7 inserted into the combustion tube 1 is positioned opposite the opening 5, so that the rotating vaporizing tube 6 and the gas chamber 3 are communicated with each other. Make it familiar.

Reference numeral 8 denotes a blower tube which extends through the vaporizer tube 6 and has an opening therethrough.

Reference numeral 9 denotes an air mixture plate attached to the open end of the carburetor cylinder 6 with a gap 10 sufficient for scattering particulate fuel, and a moisture passage 11 is provided in the center of the air mixture plate 9. There is.

Reference numeral 12 denotes a fume chamber located between the inner bottom wall 2a of the combustion plate 2 and the air mixture plate 9, and around the opening 5 of the gas chamber 3; It is connected to a ventilation chamber (not shown) through the air supply chamber.

Note that the above-mentioned blower tube 8 is also connected to the blower chamber.

A fumarole passage 14 capable of blowing forced air obliquely upward is formed between the moisture plate 9 and the fumarole chamber 12, and a fumarole passage 15 is opened on the bottom side of the fumarole chamber 12, so that the forced air By causing the steam to flow along the inner bottom wall 2a of the combustion disk 2, accidents caused by burnout of the combustion disk 2 can be completely eliminated.

Reference numeral 16 denotes an ignition plug inserted into the combustion disk 2.

Inside the center inside the tip of the vaporizing tube 6 configured as described above, a hollow diffusion tube 17 having an inverted conical shape is formed integrally with the base 17a on the large diameter side so as to form a fumarole gap 18. The diffusion tube 17 is fitted onto the rotating shaft 7 so that the objects are brought into close contact with each other, and the inner and outer surfaces of the diffusion tube 17 are arcuate to form fuel suction and diffusion surfaces 19a and 19b.

On the free end side of the diffusion tube 17, a fuel reservoir tube 20 is arranged in a non-rotatable state and has a U-shaped cross section so that the free end side of the diffusion tube 17 can be inserted into the fuel reservoir tube 20. On one side of the reservoir cylinder 20, the distal end side of the oil feed pipe 21 is inserted and opened, and the fuel supplied from the oil feed pipe 21 to the diffusion cylinder 17 is provided with fuel suction and diffusion surfaces 19a formed on the inner and outer surfaces of the diffusion cylinder 17, respectively. , 19b toward the inner surface of the vaporizer cylinder 6, thereby causing the fuel to be absorbed by the suction surface 19a,
Even if either one of 19b becomes unable to be sucked up for some reason, the fuel can be sucked up using other suction and diffusion surfaces, and a stable oil feeding action can be maintained, resulting in good raw combustion and Vaporization combustion can be performed.

Next, the operation of the present invention will be explained.

Now, in the figure, the rotating shaft 7 is rotated to rotate the vaporizing tube 6 and the diffusion tube 17 together, and at the same time forced air is sent from the blowing chamber through the blowing tube 8 and the air passage 13 to the vaporizing tube 6 and the fumarole chamber 1.
2. Painting style.

Then, a part of the forced air flowing in the blast tube 8 is directly blown into the vaporization tube 6, and the other part flows through the diffusion tube 17 and then flows through the fumarole gap 18 to the inner surface of the vaporization tube 6. The gas is injected into the gas chamber 3, and finally, the gas is ejected all at once from the numerous gas ejection holes 4 toward the vaporization tube 6, and the forced air supplied into the fumarole chamber 12 flows through the fumarole passage 14 and the fumarole passage. 15 to the inner bottom wall 2a of the combustion disk 2 to form an air curtain on the inner bottom wall 2a of the combustion disk 2, and the combustion disk 2 is cooled by the air curtain.

Under such conditions, when fuel is sent through the oil transfer pipe 21, the fuel enters the fuel receiving tube 20 from the oil transfer tube 21, and then passes through the fuel suction tube provided on the inner and outer surfaces of the diffusion tube 17. Diffusion surface 19a.

After being sucked up along the direction 19 b, the forced air flowing through the fumarole gap 18 scatters the gas toward the inner surface of the vaporization cylinder 6 .

Therefore, even if a situation occurs in which the fuel suction action becomes impossible or unsmooth due to adhesion of dust to one of the inner and outer surfaces of the fuel suction diffusion surface 19a or 19b during the oil feeding process, the fuel receiving cylinder Since the fuel in the fuel tank 20 can be accurately sucked up using the other suction and diffusion surfaces and transferred to the inner surface of the vaporizing cylinder 6 in a diffusive manner, the oil feeding action can always be carried out in a stable state.

As described above, the fuel supplied to the inner surface of the vaporization tube 6 is smoothly diffused by the centrifugal diffusion effect caused by the rotation of the vaporization tube 6 and the jetting effect of the circulating forced air, and then is dispersed into fine particles from the gap 10. As a result, it is scattered onto the inner surface of the combustion disk 2, and is quickly ignited to cause raw combustion, thereby heating the vaporization cylinder 6.

As a result, the fuel sent through the oil pipe 21 quickly becomes vaporized gas due to the preheating effect while diffusing on the inner surface of the vaporization cylinder 6, and the generated vaporized gas mixes with the flowing forced air and completely completes the process. The gas becomes a humid gas that is pressurized into the gas chamber 3, and is vigorously combusted through the numerous gas ejection holes 4, allowing vaporization and combustion to continue satisfactorily over a long period of time.

In short, since the present invention has the above-mentioned configuration, in the process of diffusing fuel to the inner surface of the vaporization tube 6 using the diffusion tube 17, the fuel suction and diffusion surface provided on the diffusion tube 17 is free from dust. Even if a situation occurs where the suction and diffusion effect becomes impossible or unsmooth due to adhesion or other causes, the fuel receiving cylinder 2
The fuel fed into the cylinder 6 can be sucked up by the fuel sucking and diffusing surface 19a or 19b on either the inner or outer surface, and the fuel can be sent to the inner surface of the vaporization cylinder 6 while being diffused.

Therefore, in the present invention, the fuel suction diffusion surface 19
By providing a and 19 b particularly on the inner and outer surfaces of the diffusion tube 17, a constant amount of fuel can always be stably supplied to the inner surface of the vaporization tube 6, so that not only raw combustion but also vaporization combustion can be stably continued. Make the most of your efforts.
