Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vaporizing liquid fuel combustion device that uses petroleum as fuel.

[Conventional technology] FIG. 2 shows an example of a conventional vaporized liquid fuel combustion device.

A vaporizer lid 3 is placed on the top of the vaporizer 2 in which the heater 1 is embedded.
are arranged integrally for thermal conduction, and a burner section 4 is connected to the burner section 4 through an outlet opening formed near the center thereof. A rotor 6 is disposed in the inner space of the carburetor 2 by a motor 5 provided below the carburetor 2 . A diffusion vane 7 is integrally arranged on the rotor 6. A combustion fan 8 is integrally fixed to the motor 5 below the rotor 6, and a case 9
surrounded by One end of the oil supply pipe 10 faces near the rotor 6, and the other end faces the oil supply tank 12.
The fuel pump 11 is connected to the oil supply pump 11 disposed on the top of the tank.

When the heater 1 is energized and the vaporizer 2 reaches a predetermined temperature, the motor 5 is driven and the rotor 6, diffusion blade 7, and combustion fan 8 are rotated. On the other hand, the fuel is supplied by the fuel pump 11
The oil is discharged onto the potter's wheel through the oil supply pipe 10, and is evenly dispersed and atomized from the outer periphery of the diffusion layer 17 by the centrifugal force of the rotating rotor 6 and the diffusion layer ff17.

The atomized fuel is vaporized on the heated inner wall of the vaporizer 2 and mixed with combustion air supplied by the combustion fan 8 to form a mixed gas.

The mixed gas is further uniformly mixed by the rotating diffusion vane II7, reaches the burner section 4 through the outlet opening of the carburetor lid 3, and is ignited and burned by an igniter (not shown).

[Problem to be solved by the invention]

However, with the above configuration, there is a limit to the range in which the combustion amount can be varied, and when increasing the combustion capacity by increasing the number of burners to two or two, the number of combustion fans must be increased by the same number. However, there was a major problem in that it required a large installation space.

The present invention is intended to solve these conventional problems, and aims to make it easy to add burners, easily increase combustion capacity, and widen the variable range of combustion amount.

(Means for Solving 1g) In order to solve the above problems, the liquid fuel combustion device of the present invention includes a plurality of vaporizers provided on one burner base, and a plurality of vaporizers provided above each of the vaporizers. a plurality of burner heads disposed, a plurality of rotary atomizing means for liquid fuel disposed inside each of the vaporizers, a blower box formed at a lower part of the burner base, and a blower box formed in the blower box. It is comprised of one provided combustion fan and a plurality of motors that rotate each of the rotary atomizing means disposed through the ventilation box.

[Function] With the above-described configuration, one rotary burner is formed by a motor, a rotary atomizing means, a diffusion vane, a vaporizer, and a set of burner heads, and each rotary burner is connected to the rotary burner through a blower box. Since combustion air can be supplied from a single combustion fan, it is possible to add more rotary burners on the burner base.

[Embodiment] An embodiment of the present invention will be described with reference to FIG. 1 of the accompanying drawings.

In FIG. 1, a plurality of vaporizers 15 in which heaters 14 are embedded are provided on one burner base 13, and a mixing chamber 17 in which a baffle plate 16 is disposed above the vaporizers 15 is shown. is provided, and a burner head 18 is provided at the upper opening of this mixing chamber 17. A rotary atomizing means 19 for liquid fuel is disposed inside the vaporizer 15.
A diffusion vane 20 is integrally provided with the rotary atomization means 19 . The rotary atomizing means 19 and the diffusion vanes 20 pass through the blower box 21 formed at the lower part of the burner base 13.
A motor 22 that rotates the is fixed to the bottom of the case 23. A combustion fan 2 is installed at the bottom of the ventilation box 21.
4 are arranged.

The exterior of the carburetor 15 is surrounded by a carburetor cover 25 and is insulated, and a fuel supply pipe 2 is provided near the rotary atomization means 19.
6 is coming. The other end of the oil supply pipe 26 is connected to the oil supply pump (
(not shown).

In the above configuration, the rotation of the motor 22 causes the rotary atomization means 19 to rotate, and the operation of the oil supply pump (not shown) causes the liquid fuel to pass through the oil supply pipe 26 to the rotation atomization means I.
9. The liquid fuel supplied to the rotary atomization means 19 is atomized by centrifugal force, collides with the vaporization surface of the inner wall of the vaporizer 15, and is vaporized. The vaporized fuel gas is mixed with a portion of the combustion air supplied by the combustion fan 24 to form a mixed gas. The mixed gas is further uniformly mixed by the rotating diffusion vane 20 and conveyed to the mixing chamber 17, where it is mixed with the remaining combustion air, dispersed by the baffle plate 16, and ejected from the burner head 18. ) and ignites and burns.

In this way, this liquid fuel combustion device includes the motor 22, the rotary atomizing means 19, the diffusion vanes 20, the vaporizer 15, and the mixing chamber 1.
7, one rotary burner is formed by one set of the baffle plate 16 and the burner head 1B, and a combustion fan 2 is connected to each rotary burner via a ventilation box 21.
Since combustion air can be supplied from 4, burner base 13
Rotary burners can be easily added to the top, and by turning on and off multiple rotary burners, the combustion amount can be varied over a wide range, and the installation space can also be reduced.

〔Effect of the invention〕

The liquid fuel combustion device of the present invention includes a plurality of vaporizers provided on one burner base, a plurality of burner heads arranged above each of the vaporizers, and an interior of each of the vaporizers. a plurality of rotary atomizing means for liquid fuel disposed in the burner base, a blower box formed at the lower part of the burner base, one combustion fan provided in the blower box, and a combustion fan extending through the blower box. and a plurality of motors for rotating each of the disposed rotary atomizing means,
It is possible to easily add rotary burners on the burner base, and by turning on and off a plurality of burners, the combustion amount can be varied over a wide range, and the installation space can be reduced, which is a great effect.
