Description

[Detailed Description of the Invention] The present invention relates to preventing oil droplets from falling in a rotary vaporizing burner.

Conventionally, in a rotary vaporizing burner that burns upward, the rotor cup placed in the center of the combustion tube opens downward, the oil pipe is inserted into the cup from below, and the oil feed port opens upward or sideways. was. The oil sent out from the oil pipe was supplied through a small gap to a diffuser that was integrally attached to the center of the rotor cup. However, because there is a gap between the diffuser and the oil pipe, the oil droplets do not transfer to the diffuser.
Either it would fall straight down, or it would run down the axis of rotation. As a result, the amount of oil being combusted was small relative to the amount of oil being fed, resulting in poor efficiency.Furthermore, since the amount of falling oil droplets was not constant, the amount of oil supplied to the rotor cup fluctuated, resulting in unstable combustion. In addition, the oil that dripped down the shaft was applied to the electric motor that rotates the rotor cup, causing failure. As a countermeasure, a non-rotating saucer is installed under the oil supply port.
Therefore, there is a device that receives the falling oil droplets and transfers the accumulated oil to a diffuser, but since the diffuser rotates, it is necessary to provide a gap between it and the saucer, and through this gap, the rotation axis is transmitted. Since the oil droplets drip, no great effect can be obtained, and the sealing means for this gap requires a device with a complicated structure.

The present invention solves the above-mentioned difficulties, makes it difficult for oil droplets to fall, and even if they do fall, all of the falling oil droplets are re-combusted. Explain.

FIG. 1 is a cross-sectional view of one embodiment of the present invention, in which 1 is a bottomed combustion tube with a flame port on the inner surface and a gas chamber 2 inside, and an opening 3 provided in the center of the gas chamber 2. A rotating shaft 4 is inserted into the combustion cylinder 1 so as to protrude long toward the combustion cylinder 1 side.
A hollow cylindrical rotor cup 5 with an opening at the bottom is fixed to the upper end of the rotating shaft 4 so as to have a scattering gap 6 between it and the opening 3, and the lower end is directly connected to an electric motor 7 so that it can be rotated. ing. An inverted circular diffuser 8 is attached to the center of the interior of the rotor cup 5, and an oil feed pipe 10 extending from an oil feed pump 9 opens at the side of the diffuser 8 with a slight gap. A swirler blade 11 is located below the diffuser 8 at the portion where the rotating shaft 4 is inserted into the rotor cup 5.
The swirling blade 11 is provided to rotate integrally with the swirling blade 11.
As shown in FIG. 2, it is composed of oil stops 12 and 13, a scattering part 14 at the tip thereof, and a blowing part 15. Further, a blower tube 16 is provided at the center of the bottom of the combustion tube 1.
has been inserted.

The present invention has such a configuration, which drives the electric motor 7 to rotate the rotary shaft 4, and simultaneously rotates the blower tube 1.
Air is blown into the rotor cup 5 from 6. When the oil pump 9 is driven, oil is pushed out from the oil pipe 10 toward the diffuser 8, adsorbs on the surface of the diffuser 8, and moves along the surface of the diffuser 8 toward the rotor cup 4 while forming a thin film. go. Near the opening of the oil pipe 10, in addition to the wind from the blower tube 16, an upward air flow generated by the wind blowing part 15 of the swirler blade 11 provided below the diffuser 8 is added, and the diffuser 8
Although oil droplets are prevented from falling through the gap between the oil supply pipe 10 and the oil supply pipe 10, oil droplets that do not successfully transfer to the diffuser 8 either fall straight down from the mouth of the oil supply pipe 10 or are removed from the diffuser 8. It hangs down towards the rotating shaft 4. The oil droplets that have fallen directly below are caught by the oil stop 13 of the swirler 11, and the oil droplets that have traveled along the rotating shaft 4 are caught by the oil stop 12, and the centrifugal force sends them from the scattering part 14 at the tip of the swirler 11 to the rotor. It is blown onto the inner surface of the cup 5 and attached to the inner surface of the rotor cup 5. Then, it mixes with the oil that has migrated on the surface of the diffuser 8 and diffused on the inner surface of the rotor cup 5, and initially it scatters from the scattering gap 6 and burns droplets, and as the rotor cup 5 is heated by the combustion heat. It is vaporized in the rotor cup 5, and the gas chamber 2
It is sent to the flame and ejects from the flame port and burns.

As described above, the present invention provides a swirling vane consisting of an oil stop part, a scattering part, and a wind blowing part that rotates together with the rotating shaft below the diffuser, so that the upward wind generated by the wind blowing part is The force makes it difficult for oil droplets to fall, and even if they do fall, they are caught by the oil stopper, scattered from the scattering part to the rotor cup, and re-supplied to the inner surface of the rotor cup as vaporized fuel. Can be supplied to the cup.
That is, it eliminates fluctuations in the amount of oil supplied to the rotor cup, making stable combustion possible, and also prevents oil droplets from splashing on the motor, thereby reducing failures.
