Description

[Detailed Description of the Invention] The present invention relates to a vaporizing cylinder of a vaporizing burner. The liquid fuel sprayed into the combustion chamber is ignited from the fuel scattering edge of the rotating vaporization cylinder, resulting in live combustion.This combustion heats the vaporization cylinder, vaporizes the liquid fuel in the vaporization cylinder, and opens the vaporization cylinder. For example, a device that gasifies and burns vaporized gas by introducing it into a gas chamber that communicates with the end and ejecting the vaporized gas from the gas chamber into the combustion chamber is
It is known from Publication No. 56-52119.

However, in this case, a wire mesh is placed on the inner surface of the vaporization cylinder to prevent the fuel from sliding down from the inner circumferential surface of the vaporization cylinder.

To install this wire mesh, it is necessary to attach it uniformly and closely to the inner wall of the carburetor cylinder, but special means are used to install it tightly, and the assembly is troublesome, and the fuel runs in a straight line on the inner wall of the carburetor cylinder. Since the fuel flows downward, the contact time with the high-temperature part at the top of the vaporization cylinder is short, and therefore the vaporization cylinder needs to be made that large.Furthermore, when the fire is extinguished, odor is generated due to the fuel remaining between the vaporization cylinder and the wire mesh. There are inconveniences such as

The purpose of the present invention is to obtain a vaporizing cylinder for a vaporizing burner that does not have such inconveniences. and burn it live,
This raw combustion heats the vaporization cylinder 1 to vaporize the liquid fuel in the vaporization cylinder 1, and guides the vaporized gas into the gas chamber 4 that communicates with the open end of the vaporization cylinder 1, and from the gas chamber 4 into the combustion chamber 3. In a vaporizing burner which blows out vaporized gas to gasify and burn it, a spiral spring 5 is arranged along the inner circumferential surface of the vaporizing cylinder 1.

In the illustrated embodiment, the vaporization cylinder 1 is supported on a rotating shaft 8 that stands up from the upper end of a motor 7 provided in an air supply chamber 6, and a diffusion cylinder 9 is attached to the inner upper end of the vaporization cylinder 1. A fuel supply pipe 10 is placed inside the diffusion tube 9 to uniformly supply fuel to the inner circumferential surface of the vaporization tube 1 through the diffusion tube 9.

In the drawing, 11 is a turbo fan mounted on a rotating shaft 12 protruding from the lower end of the motor 8, and 13 is a blow cylinder 14 facing into the carburetor cylinder 1 from the air feed chamber 7, which connects the air feed chamber 7 and the cold air blow chamber 15. Connecting passages 16 and 17 are blowholes through which air from the air blowing chamber 7 is ejected from the cold air blow chamber 15 in an air curtain shape, 18 is a spark plug facing into the combustion chamber 3, 19 is a flame rod, and 20 is a drain. It's a pipe.

In the illustrated embodiment, only the upper end of the helical spring 5 is attached to the inner surface of the vaporizer cylinder 1 by spot welding or other means, so that the helical spring 5 can freely expand and contract due to thermal expansion.

In this case, the spiral spring 5 is installed so that when the carburetor cylinder 1 rotates clockwise, the spiral spring 5 is wound counterclockwise.
As the carburetor cylinder 1 rotates, the spiral spring 5 is brought into close contact with the carburetor cylinder 1.

Next, to explain the vaporization of fuel in the vaporization tube, when the vaporization tube 1 is rotated and fuel is supplied from the fuel supply pipe 10 into the diffusion tube 9, the fuel is transferred to the vaporization tube 1.
The fuel is uniformly supplied to the inner circumferential surface of the fuel tank, flows down along the spiral spring 5, is scattered from the fuel scattering edge 2 into the combustion chamber 3, and is ignited and burned when it touches the spark of the ignition plug 18, and is vaporized by the heat. The tube 1 is heated, and most of the fuel supplied into the vaporization tube 1 evaporates as soon as it touches the vaporization tube 1, and the remaining fuel evaporates while flowing over the upper edge of the spiral spring 5.

Especially when the surface temperature of the vaporizer cylinder 1 becomes high,
A portion of the fuel becomes spherical and slides down the inner peripheral surface of the carburetor cylinder 1, but when the spiral spring 5 is provided, this sliding fuel is moved along the spiral spring 5 and its movement is During this time, it completely evaporates. Therefore, it is possible to completely prevent the unvaporized fuel from being ejected from the fuel scattering edge 2 or the gas chamber 4 into the combustion chamber 3 and combusting in a red flame state.

In this way, according to the present invention, by arranging the spiral spring 5 along the inner peripheral surface of the carburetor cylinder 1, the fuel supplied into the carburetor cylinder 1 is caused to flow down along the upper edge of the spiral spring 5. , it is possible to vaporize the fuel while moving it over a longer distance than the conventional wire mesh type.
It is possible to completely vaporize the fuel, and it also eliminates the disadvantages of the wire mesh type, such as simply installing the spiral spring 5 in the vaporization cylinder 1, making the fabrication process easier compared to the conventional wire mesh method. It has the effect of eliminating it.
