Abstract

PURPOSE:To quickly carry out evaporation of fuel oil by providing a plurality of flow-down checking members and cylindrically disposing the same on the inner peripheral surface of an evaporating cylinder, and forming the flow-down checking members attachably and detachably to and from the inner peripheral surface of the evaporating cylinder. CONSTITUTION:At the time of evaporating a fuel oil, even if the fuel oil which has been diffused by a fuel oil diffusing member 3 and pulverized in mist-shape is sprayed to the side of the evaporating cylinder 4, the fuel oil is received by the flow-down checking member 5 and does not make contact directly with the inner peripheral surface of the evaporating cylinder 4. Therefore, the fuel oil is liquefied as it is repulsed by the heated evaporating cylinder 4, and is surely evaporated. In the case of detaching the flow-down checking member 5, if a stopper 10 is removed and the evaporating cylinder 4 is removed from a rotary shaft 2, the flow-down checking member 5 can be readily taken out of the device. When the end surface of the flow-down checking body 5 is bent inwardly of the evaporating cylinder 4 to separate a cutout portion 23 from the mounting portion 20 and thereafter is pulled to the opening side of the evaporating cylinder 4, it can be easily taken out of the evaporating cylinder 4.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a vaporizer in a burner having a flow prevention body attached to the inner circumferential surface of a vaporizer cylinder to promote gasification of fuel.

(Prior art) During the Congregation and Song Dynasty, a flow prevention body was fixed by spot welding inside the vaporization cylinder, or a rough surface was formed on the inner peripheral surface of the vaporization cylinder itself to prevent the vaporized gas from liquefying. ing.

(Problems to be Solved by the Invention) However, in the former case, if cracks or damage occur in the fixed portion, the vaporization tube and the flow prevention body must be replaced, resulting in a great deal of waste. In addition, in the latter case, when the vaporizing cylinder is heated, the rough surface formed on the inner peripheral surface is also heated, so the fuel that has been diffused by the fuel diffuser and becomes atomized is repelled by the rough surface. , gasification may be hindered.

(Means for solving the problem) In order to solve the above technical problem, the following technical measures were taken.

That is, the tip vaporizing tube (4) of the rotating shaft (2) extended into the combustion tube (1) is attached to and detached from the rotating shaft (2) so as to be adjacent to the fuel diffuser (3) and completely cover it. Attach freely to the vaporizer cylinder (
4) A plurality of flow prevention bodies (5) having a rough surface and an arcuate cross section are arranged in a cylindrical shape on the inner peripheral surface, and the flow prevention bodies (5) are connected to the vaporization cylinder (4). Constructed so that it can be installed and removed from the inner circumferential surface.

(Effects of the invention) Since the supplied fuel can be evenly dispersed and atomized into the vaporization cylinder using the fuel diffuser, the mixture with the combustion air is improved, and when this atomized fuel is scattered, it is heated. It vaporizes quickly without being repelled on the inner surface of the vaporizer cylinder.

Furthermore, if the flow prevention body (5) is damaged or becomes unusable, remove the vaporizer tube (4) and then remove the vaporizer tube (4).
Since it can be replaced separately from 4), it is cheaper, and
This exchange is also easy. Furthermore, when the flow prevention body (5) is to be attached, it can be easily done because it can be arranged in a cylindrical shape along the inner circumferential surface of the vaporization cylinder (4). Furthermore, attachment and detachment operations can be carried out in a short time by simply attaching and detaching the one among the plurality of flow-blocking bodies in which an abnormality has occurred.

(Example) Hereinafter, an example of the present invention will be specifically described based on the drawings.

First, to explain its configuration, the combustion tube (1) is provided adjacent to the ventilation chamber (7) in which the carburetor motor (6) is housed, and the combustion tube (1) has a large number of smoke holes (8a). A gas chamber (9) is formed with the wall (8).

The rotating shaft (2) is rotated and rotated by the carburetor motor (6).
A fuel oil diffuser (3) formed in a conical shape with a wider width toward the tip is integrally fixed to the tip.

The vaporizer cylinder (4) has a closed end and an open base end, is adjacent to the outside of the fuel oil diffuser (3), and is fixed to the rotating shaft (2) via a stopper α1. Then, the vaporizer cylinder (4
) is bent toward the combustion tube (1) side, and is integrally formed with the guide member (2) which is curved outward with a ring-shaped net θD having small eyes formed therebetween. welding).

The resistance plate QD is composed of a ring part Q'J and a mounting part (3 places) which is bent downward from the end surface of this ring part 0'J and protrudes. A gap is formed between the part OI and the inner surface of the vaporizing tube (4) (it is attached to the inner surface of the vaporizing tube (4)).

The flow prevention body (5) is formed of a small mesh mesh, and
A notch (to) into which the attachment part (e) of the resistance plate Q1) can be inserted is formed at the tip. In addition, the flow prevention body (5
) is curved in an arc shape along the inner surface of the vaporization tube (4), and is configured to be attachable to and detachable from the vaporization tube (4). Note that when the flow prevention body (5) is attached to the vaporization cylinder (4), the notch part (material) fits into the attachment part so that it is supported and prevented from coming off.

α is a blower tube deeply inserted into the vaporization tube (5), and forms an air mixture passage α communicating with the gas chamber C9) between the vaporization tube (5) and the gas chamber C9).

The pipe is a fuel supply pipe that is placed close to the outer surface of the fuel diffuser (3).

θ· is an air blower, and αη is an air path that communicates the air blower Qe with the air blowing chamber (7). (One scoop is an ignition device.

Next, its effect will be explained.

First, when the rotating parts of the aircraft are driven, the fuel supply pipe αO
The fuel supplied from the carburetor falls onto the fuel diffuser (3), which is rotated by the carburetor motor (6), where it is transferred to the carburetor (4).
Spread evenly to the sides as a mist. The atomized fuel then passes from the blower device QQ through the air passage Q71 to the blower chamber (
7) It is mixed with the combustion air sent into the air mixture passage αΦ and is ejected into the combustion cylinder (1) from the gap (mesh 011) with the guide member (6).

On the other hand, since the ignition device (to) is energized at the same time as the power switch (not shown) is closed, the fuel ejected into the combustion tube (1) is ignited and raw combustion occurs. and,
The combustion field caused by raw combustion heats the vaporization tube (4), and when it reaches the evaporation temperature of the fuel, the fuel supplied into the vaporization tube (4) is evaporated and vaporized in the moisture passage α→. It mixes with the combustion air to form a mixed gas and is stored in the gas chamber (9). In this way, the mixed gas stored in the gas chamber (9) is transferred to the injection hole (8a) of the combustion plate (8).
From then on, fumes are emitted at a constant pressure to cause vaporization and combustion, and the vaporization and combustion state continues thereafter.

When the fuel is vaporized, even if the fuel that has been dispersed by the fuel diffuser (3) and atomized into mist is scattered toward the vaporizer cylinder (4), it is caught by the flow prevention member (5) and is directly dispersed. Since it does not hit the inner peripheral surface of the vaporizer cylinder, the heated vaporizer cylinder (4)
It can reliably vaporize without being repelled or liquefied.

When removing the flow prevention body (5), the stopper O
If Q is removed and the carburetor cylinder (4) is removed from the rotating shaft (2), it can be easily taken out of the machine together with the carburetor cylinder (4). Then, the end face of the flow prevention body (5) is connected to the vaporization cylinder (4).
) After bending it inward to separate the notch (e) from the attachment part @, it can be easily taken out from the vaporizer tube (4) by pulling it toward the opening of the vaporizer tube (4).

On the other hand, when installing it, insert it into the vaporization cylinder (4) with the end face of the flow prevention body (5) bent so that it approaches.
Then, the notch part @ should be fitted into the mounting part (a).
