Description

Detailed Description of the Invention The present invention is capable of replenishing fuel and combustion air without emitting bad odors to the surrounding area, even in indoor or outdoor workplaces where electric light lines are not installed, disaster areas, farms, or other remote mountainous areas. The present invention relates to an engine-driven burner that can achieve long-term continuous complete combustion under

Conventionally, burners have been commonly used and well known to burn liquid fuel efficiently, in which combustion air is generated using a blower driven by an electric motor, and the resulting combustion air is blown into a combustion section for combustion. It is being Therefore, in the past, when burning liquid fuel with a burner, a power source was always required to drive the electric motor. In places where there is no power source, a portable generator is prepared, and the power obtained by the portable generator drives the burner motor and blower to blow combustion air to the combustion section and cause combustion. This is what I used to do.

Therefore, in order to burn fuel with a burner in indoor workshops, outdoor workshops, farms, remote mountain areas, etc. where there is no power source, it is inconvenient that an expensive portable generator must be provided in addition to the burner, electric motor, and blower. This is something that has been strongly desired to be improved.

In view of the above, the present invention connects a discharge tube of an engine-driven blower and a blower tube equipped with a burner to form an air passage leading to the burner inside, and a discharge port of an exhaust pipe of the engine-driven blower is connected to a blower tube provided with a burner. By opening into the street, you can easily obtain and supply combustion air by directly connecting the blower to the engine and rotating it, even in indoor workplaces, outdoor workplaces, farms, remote mountain areas, etc. where electric light lines are not installed. In addition to efficiently burning liquid fuel, engine exhaust gas is also sent to the burner together with combustion air to be combusted together with the fuel, thereby preventing the foul odor of exhaust gas from being dissipated into the surrounding area during combustion. At the same time, a blowhole is opened at a suitable place in the air passage to direct a part of the fresh combustion air flowing through the air passage to the engine-driven blower, so that the radiant heat of combustion can be used to blow the air into the engine-driven blower. The present invention provides an engine-driven burner that prevents the side from being heated more than necessary and allows combustion to continue well over a long period of time.The configuration of the engine-driven burner according to the present invention is attached below. A preferred embodiment shown in the drawings will be described.

In the drawings, reference numeral 1 denotes an engine-driven blower for continuously generating a predetermined amount of combustion air by driving a blower 3 when an engine 2 is started. A blower 3, which rotatably houses a blower impeller (not shown) inside, is directly connected to one side of an engine 2, which is started by the engine. It is equipped with a tank 5, an air cleaner 6, and a muffler 7. The discharge tube 8 of the blower 3 is connected via a connecting member 11 to the base end side of a blow tube 9 equipped with a burner 10 on the tip side, and an air passage leading to the burner 10 is provided inside the discharge tube 8 and the blow tube 9. 12 is formed, and the generated combustion air is blown to the burner 10 to efficiently and completely burn the liquid fuel supplied to the burner 10 from the fuel supply pipe 13. 14 is an adjustment valve for the oil supply pipe 13.

An exhaust pipe 15 is connected to the muffler 7 , and the exhaust pipe 15 is inserted so that a discharge port 16 opened at its tip side is opened in the air passage 12 . The exhaust gas generated by the startup is forcibly blown out into the air passage 12 and sent to the burner 10 while stirring and mixing with the combustion air,
Burn with liquid fuel.

A blowhole 17 is opened at an appropriate position in the air passage 12 on the side closer to the engine-driven blower 1 before the discharge port 16 of the exhaust pipe 15, and at the position of the blower hole 17, the front of the engine-driven blower 1 is opened. A shielding plate 18 of an appropriate size so as to shield the side
has been erected. Note that the shielding plate 18 is connected to the connecting member 1
1 by an appropriate mounting means, and the proximal end portion 19 of the shielding plate 18 is made to pass through the blowhole 17 and protrude into the air passage 12, so that the air is blown up by the blower 3, and the air passage 12 is A part of the fresh combustion air blown into the air is received, and the fume is distributed upward while being diffused from the jet nozzle 17 along the shielding plate 18. The front side of an engine-driven blower 1 is cooled to prevent the engine-driven blower 1 from being heated more than necessary due to the radiant heat of a burner 10, thereby making it durable for long-term use.

The burner 10 shown in FIG. 1 is a vertical type in which the combustion flame is directed upward, but this can be changed to a second embodiment shown in FIG. A horizontal burner 10' for blowing a flame may be attached to the tip side of the blast tube 9. In that case, the length of the blower tube 9 may be shorter than the length of the blower tube 9 of the first embodiment.

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

Now, if the recoil starter 4 is operated to start the engine 2 in FIG. and continuously supplies it to the burner 10. When fresh combustion air is now being sent to the burner 10 in this way, adjust the fuel adjustment valve 14 to supply a predetermined amount of liquid fuel to the burner 10 via the fuel supply pipe 13 and start ignition. For example, the liquid fuel is completely combusted with supplemental combustion air and used as a suitable heating source.

By the way, the exhaust gas discharged from the engine 2 at the same time as the above-mentioned combustion occurs is discharged into the air passage 12 from the discharge port 16 through the exhaust pipe 15, and is stirred and mixed with the circulating combustion air. It is sent to the burner 10 and burned. Therefore, all of the exhaust gas generated during operation of the engine 2 is combusted by the burner 10, so the bad odor of the exhaust gas is not dissipated to the surroundings, and the workers are not affected by the bad odor. Prevented. On the other hand, while combustion continues, a part of the fresh combustion air blown up is received by the base end 19 of the shielding plate 18 and moves upwardly from the jet nozzle 17 along the shielding plate 18. The fumes are distributed, forming an air layer on the surface of the shielding plate 18, and forming an air layer on the front side of the engine-driven blower 1 and the shielding plate 18.
Let it air cool.

Therefore, no matter how large the combustion amount of the burner 10 is, the radiant heat of the burner 10 prevents the engine-driven blower 1 and the engine oil tank 5 from heating up more than necessary, and the engine is always kept running. By inhaling fresh air, combustion can continue for a long time under efficient and sanitary environmental conditions, even in indoor workplaces without power, outdoor workplaces, disaster areas, farms, or remote mountain areas. can be easily achieved.

In short, the present invention connects the discharge tube 8 of the engine-driven blower 1 and the blower tube 9 equipped with the burner 10 to form an air passage 12 leading to the burner 10 inside, and the exhaust pipe 15 of the engine-driven blower 1 The discharge port 16 is opened into the air passage 12, and a part of the fresh air flowing through the air passage 12 is driven by the engine at a suitable position in the air passage 12 before the position of the discharge opening 16 of the exhaust pipe 15. Since the blower port 17 is opened to cause a jet of gas toward the blower 1, even in an indoor workshop without an electric light line, an outdoor workshop, a disaster area, a farm, or a remote mountainous area, the engine-driven blower 1 can be operated. Not only can the combustion air be sent to the burner 10 to efficiently and completely burn the liquid fuel, but also the exhaust gas exhausted during operation of the engine-driven blower 1 is mixed with the combustion air and sent to the burner 10. 10, it is possible to burn it together with liquid fuel, prevent the release of bad odor into the surrounding area, and maintain sanitary environmental conditions.
A portion of the fresh combustion air is jetted from the jet nozzle 17 toward the engine-driven blower 1 to cool the engine-driven blower 1.
Even if the amount of combustion is large, the radiant heat does not cause the engine-driven blower 1 to reach an unnecessarily high temperature, allowing good combustion to continue over a long period of time and allowing the engine to always take in fresh air.
