Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a liquid plate fuel combustion apparatus for atomizing supplied liquid fuel.

<Prior Art> As a conventionally used liquid fuel combustion apparatus, for example, a liquid fuel combustion apparatus disclosed in Japanese Utility Model Publication No. 60-9542 is known. In this case, in the fuel supply and atomization mechanism, the fuel ejected from the upper surface of the fixed plate is atomized by the rotary scattering plate having the interval t (about 0.6 mm or less).

<Problems to be Solved by the Invention> However, there are the following problems in supplying fuel to the rotary scatter plate here.

(1) When the distance t between the fixed plate and the rotary scatter plate is 0.6 mm or less, the fuel smoothly moves to the rotary scatter plate and there is no problem in atomization and vaporization, but the interval t is 0.6 mm or more. In this case, some of the rotary scatter plates cannot move the fuel, and the fuel stays on the fixed plate, and when the amount of the stagnant water exceeds a certain amount, the fuel suddenly drops on the vaporizing surface, and breathing phenomenon appears in vaporization and combustion.

(2) Also, the pool drops from the central part of the fixed plate and causes oil leakage.

(3) It is extremely difficult to control the gap between the fixed plate and the rotary scattering plate to be 0.6 mm or less. The present invention has been made in view of the above circumstances, and an object thereof is to provide a liquid fuel combustion apparatus which eliminates the above defects by improving the legs of the fixing plate.

<Means for Solving Problems> In the present invention, a vaporization chamber and a burner head for burning a mixed gas of fuel and air vaporized in the vaporization chamber are provided, and the vaporization chamber has a fixing plate and the fixing plate. Is a liquid fuel combustion device that has a rotary scatter plate provided on a fixed plate with a gap, and supplies fuel between the fixed plate and the rotary scatter plate, wherein the fixed plate is a disc shape, Around this, there are provided fixing legs and a plurality of fuel flow-down legs separately from the fixing legs.

<Operation> Due to the above configuration, the fuel accumulated on the fixing plate flows not only to the fixing legs but also to the bottom of the vaporization chamber not only through the fixing legs but also through the plurality of legs provided separately from the fixing legs. Therefore, vaporization is performed continuously and there is no combustion of the breathing phenomenon. In addition, since the fixing plate has an upward burring hole in the center,
There is no oil leakage from the central part that will be the motor shaft hole.

<Embodiment> Hereinafter, the present invention will be described in detail with reference to the drawings of an embodiment.

Reference numeral 1 denotes a fixing plate disposed on the burner ventilation port 3 on the upper surface of the air supply housing 2. The fixing plate 1 has a disc-like fixing plate shape and has a predetermined fixing leg (3 in FIG. ) Is bent, and a plurality of (6 in the figure) legs 5 for fuel flow-down (thin legs in FIG. 3) are formed in the middle of the leg 4,
In addition, the burring hole 7 facing upward is formed in the central portion that becomes the motor shaft hole.
It has a structure that has formed. Reference numeral 8 denotes a rotary scattering stirrer disposed on the fixed plate 1 at a predetermined interval t. The rotary scattering stirrer 8 comprises a rotary scattering plate 9 and a stirring blade 11 facing the burner head 10 side, and is attached to the center. Motor shaft 12
Is connected to the motor 13 in which the fixed plate 1 is housed in the lower part of the air supply housing 2, and a fan 14 is provided in the middle of the motor shaft 12.
Reference numeral 15 is a fuel supply pipe connected to a pump 17 provided in the oil reservoir 16, and the fuel supply pipe 15 faces the upper surface of the fixed plate 1.
Reference numeral 18 is a burner, 19 is a vaporization chamber, and 20 is a peripheral wall of the vaporization chamber.

To explain this action, first, when the ignition plug 21 is ignited, the liquid fuel in the oil reservoir 16 is guided to the upper surface of the fixed plate 1 via the fuel supply pipe 15.

Here, the fuel accumulated on the fixed plate 1 continuously flows down into the vaporization chamber 19 through a plurality of thin fuel flow-down legs 5. In this case, the fuel is atomized by the rotary scattering plate 9 and supplied to the vaporization chamber 19 when the distance t between the fixed plate 1 and the rotary scattering plate 9 becomes 0.6 mm or more. Since it is supplied to the vaporization chamber 19 from the leg 4 of the book, vaporization is continuously carried out, and inconvenience such as combustion of breathing phenomenon does not occur.

At the same time, since the fixing plate 1 itself has an upward burring hole 7 in the center thereof, oil leakage from the center is eliminated. Furthermore, by making the inner diameter of the fuel supply pipe 15 about 0.8φ from the conventional 1.3φ, the fuel easily moves to the fixed scatter plate 9, and the distance t between the fixed plate 1 and the rotary scatter plate 9 becomes
Compared with this type of conventional one, it can be more than doubled and the control size can be relaxed.

<Effect of the Invention> As described above, in the liquid fuel combustion apparatus of the present invention, the fixing plate disposed in the vaporization chamber and below the rotary scatter plate has a plurality of legs in addition to the predetermined fixing legs. By installing the fuel, the fuel accumulated on the fixed plate continuously flows down into the vaporization chamber and is vaporized, so that the burner ignition does not cause a breathing phenomenon. Also, if the distance between the fixed plate and the rotary splatter plate becomes wide, even if there is fuel that cannot move to the rotary splatter plate due to the surface tension of the fuel, etc., there is an upward burring hole in the center of the fixed plate, which causes oil leakage. There is a practical effect such as not doing.
