Abstract

PURPOSE:To prevent occurrence of vibration during rotation and enable quiet gasification and combustion to be continuously maintained by a construction wherein the length of revolving shaft is reduced by forming the gasifying cylinder in a forwardly divergent shape. CONSTITUTION:If an air mixing inner cylinder 5 and a gasifying outer cylinder 6 are rotated concentrically at a high speed by a revolving shaft 4, while forced air is allowed to flow into an air passage 3, then the forced air flows through an air mixing gas passage 11 in the direction shown by arrows to eject forcibly from a main flame passage 15 and a sub-flame passage 16 towards the leading end and bottom wall 2 of a combustion cylinder 1 and also part of the forced air from the air passage 3 is spouted through a draft passage 17 along the bottom wall 2 of the combustion cylinder 1. If, under this condition, fuel oil is fed through a fuel oil supply pipe 18 towards the base end of the revolving gasifying cylinder 6, then the fuel oil is continuously moved along the inner surface of the cylinder 6 from its bace end to its leading end by the action of the centrifugal force generated by rotation and by ejection of the forced air. As a result, the fuel oil is ejected from a primary fuel oil spouting end 8 to the inner surface of a concentrically revolving jet gas branch cylinder 12, and further it is ejected from a secondary fuel oil spouting end 13 fitted to the leading end of the cylinder 12 to the inner surface of the combustion cylinder 1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to promote the production of live combustion phosphorus by atomizing the supplied fuel even when using a vaporizing outer cylinder that is open from the proximal end to the distal end. The temperature of the vaporization atmosphere is raised to a temperature sufficient to evaporate the fuel in the vaporization cylinder within a short period of time, and then the supplied fuel is rapidly evaporated and vaporized to complete warm gas. The present invention also relates to a vaporizing burner that can maintain good vaporized combustion over a long period of time by emitting flames in a branched manner toward the bottom wall of the combustion cylinder to efficiently heat the vaporizing outer cylinder.

The present applicant has previously developed a vaporizing burner that automatically shifts the fuel supplied by a rotating vaporizing tube from a semi-burned state to a vaporized state to maintain good vaporized combustion over a long period of time. It is well known that it has been developed and has achieved considerable effects as it has been put into practice.

By the way, in conventional vaporizing burners of this kind, the vaporizing cylinders for burning raw fuel or superoxidizing and vaporizing hot gas are all closed at the tip end and open at the base end. had been adopted.

However, even if the above-mentioned carburetor cylinder has a shape that is completely opposite to the conventional carburetor cylinder, with the direction open from the proximal end to the distal end, if the same vaporizing combustion instant as described above can be achieved, the length of the rotating shaft will be Not only can a vaporizing burner be provided at a lower cost by significantly shortening the time, but also by preventing the occurrence of the rotational shaking phenomenon as much as possible, it is possible to continuously maintain quieter vaporizing combustion with fewer failures.

In view of the foregoing, the present invention includes an air-fuel mixture cylinder with one tip open and the base end closed in a combustion phosphorus cylinder with an open tip and a ventilation passage provided on the bottom wall of the base, and an air-fuel mixture cylinder with one tip open and the base end closed. Next fuel splash end and base end 1
A vaporizing outer cylinder with an open air supply window communicating with the Ilk air passage is arranged so as to be able to rotate concentrically, and a tip is open between the air mixture inner cylinder and the vaporizing outer cylinder, and a proximal end is connected to the air passage. In addition to forming a hot gas passageway through which the air flows, fume gas branch pipes are integrally installed at intervals on the outer periphery of the primary fuel scattering end of the vaporizing outer cylinder, the tip of which is the secondary fuel scattering end. The end open side of the gas passage is divided into a main jetting path that spews smoke toward the tip 111 of the combustion cylinder, and a submerging path that jets flame toward the bottom wall of the combustion cylinder along the vaporization outer cylinder. Even if the outer cylinder is opened from the proximal end to the distal end, it will automatically shift from the raw combustion state to the vaporized bisque firing state, which will prevent malfunctions. The purpose of this invention is to provide a tight burner that can vaporize combustion φ quietly without any noise.The structure of the vaporizer burner according to the present invention will be described below with reference to a preferred embodiment shown in the accompanying drawings.

The end wall 7 portion on the open end side is bent toward the inner circumferential surface of the clay cylinder 1, and the terminal end of the stiff end wall 7 is used as the primary fuel @ dispersed end 8, and a ventilation passage 3 is provided in the central part of the proximal end side. A connecting member 20 connects the vaporizing outer cylinder 6 which has an air supply window 9 that communicates with the connecting member 20, so that they can be directly connected concentrically and rotated. In addition, the mixed inner cylinder 5
The end wall 10 of the open end @j is also bent toward the inner circumferential surface of the combustion tube 1, similar to the vaporizing outer tube 6. - And between the air mixture inner cylinder 5 and the vaporizing outer cylinder 6, there is a hot gas passage 11 which is open at the tip and communicates with the ventilation passage 3 from the base end side.
At the same time, on the outer periphery of the primary fuel scattering end 8 of the vaporizing outer cylinder 6, a fume gas branch pipe 12 having a secondary fuel scattering end 13 at its tip is integrated via several mounting members 14. The main flame passage 15 and the vaporizing outer cylinder 6 are attached to the main flame passage 15 and the vaporizing outer cylinder 6, which direct the open end side of the hot gas passage 11 toward the front end side of the combustion cylinder 1.
The bottom 1i12IHC direction of the combustion tube 1 is formed so as to branch into a sub-flame path 16 along which the flame is emitted.

1T is a ventilation passage connected from the base end side to the ventilation passage 3 between the base end side of the vaporization outer cylinder 6 and the bottom wall 2 of the combustion cylinder 1, and a portion of the forced air is supplied from the ventilation passage 17. The combustion tube 1 is injected into the combustion tube 1 along the bottom wall 2 of the combustion tube 1 to prevent heating loss of the combustion tube 1. Reference numeral 18 denotes an oil feed pipe whose tip is visible toward the inner surface of the vaporizer outer cylinder 6 through an air feed window 9 provided on the base end side of the vaporizer outer cylinder 6;
Reference numeral 9 denotes an ignition plug disposed within the combustion cylinder 1 at a position corresponding to the secondary fuel scattering end 13.

The vaporizing burner shown in FIG. 2 is an embodiment in which the base end side of the moisture inner cylinder 5 is used to promote fuel atomization. A hollow inverted conical fuel diffuser 21 is integrally attached to the center of the inner surface on the base end side of the cylinder 5 so that a fuel flow gap 22 is formed between it and the air-fuel mixture inner cylinder 5. The structure is the same as that of the vaporizing burner shown in FIG. 1, except that the tip of the oil feed pipe 18' is shown on the inner base end side.

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

Now, in FIG. 1, if the hot air inner cylinder 5 and the vaporizing outer cylinder 6 are caused to concentrically rotate at high speed by the rotating shaft 4, and at the same time forced air is circulated in the ventilation passage 3, the forced air will be used to generate air-fuel mixture gas. Passage 1
1 through the main flame passage 15 and the sub-flame passage 16 in the direction of the arrow, and forcefully flows toward the tip side and bottom wall 2 side of the combustion tube 1, and forced air from the ventilation passage 3. A part of the air is blown along the bottom wall 2 of the combustion tube 1 through the ventilation passage 1T.

In this state, when fuel is sent from the oil pipe 18 to the base end of the rotating vaporizer outer cylinder 6, the fuel is rotated on the inner surface of the vaporizer outer cylinder 6 by the action of centrifugal force and the injection action of forced air. Continuously moving from the base end to the distal end, the primary fuel splashing end is sprayed onto the inner surface of the fume gas branch tube 12 that rotates concentrically, and furthermore, this sprayed melt oil is sprayed onto the inner surface of the fume gas branch pipe 12, which rotates concentrically. It is sprayed onto the inner surface of the Ie brick 1 from the secondary fuel spray 1113 provided at the tip @ of the cylinder 12. Therefore, the sprayed fuel becomes more atomized by the primary and secondary spraying action, so the spark plug 19
The starting layer of raw P phosphorus is quickly fired, the fuel is completely combusted, and a part of the rising raw combustion flame is transferred to the bottom wall 2 of the combustion tube 1.
The liquid flows sideways and intensely heats the peripheral wall of the vaporizing outer cylinder 6. As a result, when the temperature inside the mixed gas passage 11 formed between the vaporizing outer cylinder 6 and the moisture inner cylinder 5 rises to the vaporizing atmosphere temperature sufficient to evaporate the fuel, the fuel is subsequently transferred. Oil pipe 1
The fuel sent to the base end side of the vaporization outer cylinder 6 through the gas mixture passage 11 evaporates and becomes vaporized gas while being transferred to the open end side of the gas mixture passage 11. It is stirred and mixed with the forced air flowing through the gas passage 11, and becomes completely humid gas, and part of it is ejected toward the tip side of the combustion tube 1 through the main smoke path 15, while the other part is ejected into the auxiliary smoke path. 16 along the vaporization outer cylinder 6 toward the bottom wall 2 of the combustion cylinder 1, and the vaporized fuel φ
While the vaporizing outer cylinder 6 is heated from the surroundings by the flame, the vaporizing combustion flame is ejected toward the tip side of the combustion cylinder 1.

In other words, if the vaporizing cylinder 6 is sufficiently heated by the vaporizing combustion flame, then the fuel sent thereafter will evaporate and vaporize during the transition, becoming a completely humid gas and being vaporized and burned continuously. By significantly shortening the length of the rotating shaft 4, the air-fuel mixture inner cylinder 5 and the vaporizing outer cylinder 6 can be rotated quietly without rotational vibration, and good vaporization combustion can be continued for a long period of time.

In short, since the present invention has the above-mentioned configuration, the vaporizing outer cylinder 6, which is capable of raw combustion or vaporization of the supplied fuel, is directed from the base end to the distal end.
Even in the open shape, it is possible to obtain good vaporization combustion similar to that of conventional vaporization burners, and the length of the rotating shaft 4 is significantly shortened, so that the air-fuel mixture inner cylinder 5 and the vaporization outer cylinder 6 can prevent rotational vibration. Cheap evaporative burners that can prevent malfunctions or poor evaporative fuel consumption.
In addition, it is possible to burn the fuel in a quiet state, and during raw combustion, the primary fuel scattering end 8 and the secondary fuel scattering end 13 promote the image particle ignition of the supplied fuel, resulting in complete combustion. φ, and the vaporizing outer cylinder 6 can be heated to the temperature of the vaporizing atmosphere within a short time, and when the vaporizing combustion is φ, the mixture gas generated in the mixture gas passage 11 is transferred from the main flame passage 15 to the tip of the combustion tube 1. While flames are ejected to the side, other air-fuel mixture gas is ejected from the cabinet blowing path 16 toward the bottom wall 2 of the combustion cylinder along the vaporizer outer cylinder 6 to heat the vaporizer outer cylinder 6 from the outer periphery. However, it has the effect of being able to perform a good superacidification of hot gas.
