(See FIG. 2).
Further, one end side of the oil supply pipe 41 is led out from the upper side wall portion 211 to the outdoor side, and is connected to the oil supply source 40 through the pump 42 and the valve 43.

The other end side of the oil supply pipe 41 is inserted into the other end side piped in the liquid storage region D2 of the water supply pipe 31 via the closing member 213 described above. More specifically, a predetermined length is inserted in the longitudinal direction L with respect to the central portion in the radial direction on the other end side of the water supply pipe 31, and a length reaching the central portion in the longitudinal direction L of the water supply pipe 31 is inserted. .

A discharge port 411 for discharging the oil E supplied from the oil supply source 40 is opened at the insertion side end of the oil supply pipe 41. The discharge port 411 is provided at a predetermined distance in the longitudinal direction L from the arrangement region D <b> 3 set on the other end side of the water supply pipe 31.

The mesh tube 50 is formed into a mesh-like tube (or tube) by a metal filament, and is immersed in the mixed fuel WE in the water supply tube 31, specifically, the outer peripheral surface of the water supply tube 31. The piping is arranged so as to surround the entire length (see FIG. 2).

One end side of the mesh tube 50 is fixed in a watertight state with respect to the outer peripheral portion of the closing member 212 described above. The other end side of the mesh tube 50 is fixed in a watertight state with respect to the outer peripheral portion of the closing member 213.
Note that the mesh of the mesh tube 50 is formed in a size and shape that allows the water W and the oil E to permeate (or pass through) (see an enlarged view of a part in FIG. 2).

Between the opposing surfaces of the water supply pipe 31 and the mesh pipe 50, a liquid storage for temporarily storing the mixed fuel WE in which the water W and the oil E discharged from the hole 311 of the water supply pipe 31 are mixed. Part 430 is formed.
While mixing the water W supplied into the water supply pipe 31 and the oil E discharged from the discharge port 411 of the oil supply pipe 41 between the opposed surfaces of the water supply pipe 31 and the oil supply pipe 41, A passage 431 for transferring toward the other end of the water supply pipe 31 is formed.

The ultrasonic vibrator 60 is mounted on the outer surface of the central portion of the lower wall portion 214 of the mixing chamber 21, and the ultrasonic vibration is substantially uniform with respect to the mixed fuel WE stored in the liquid storage region D <b> 2 in the mixing chamber 21. It arrange | positions so that it may be provided (refer FIG. 2).

The stirring device 70 includes a rotating shaft 71 that is rotatably supported with respect to one side wall portion of the mixing chamber 21, a plurality of blades 72 attached to the shaft peripheral surface of the rotating shaft 71, and a shaft end portion of the rotating shaft 71. The motor 73 is directly connected, and is provided so as to be immersed in the mixed fuel WE stored in the liquid storage region D2 in the mixing chamber 21 (see FIG. 2).

That is, the driving force of the motor 73 rotates the blades 72 attached to the rotating shaft 71 in the forward direction to agitate the mixed fuel WE stored in the liquid storage region D2 in the mixing chamber 21.
The blades 72 attached to the rotating shaft 71 may be rotated in the reverse direction, may be rotated forward and backward in the forward direction and the reverse direction, or the rotational speed may be varied.

A mixing method for mixing the water W and the oil E using the above-described fuel mixing device 20 will be described.
First, the water W supplied from the water supply source 30 and the oil E supplied from the oil supply source 40 are supplied to the water supply pipe 31 and the oil supply pipe 41 constituting the composite pipe 501, respectively. The water W supplied into the pipe 31 and the oil E discharged from the discharge port 411 of the oil supply pipe 41 are mixed (see FIGS. 1 and 2).

The inner diameter of the oil supply pipe 41 is smaller than the inner diameter of the water supply pipe 31 into which the oil supply pipe 41 is inserted, and the water is smaller than the discharge amount of the oil E discharged from the discharge port 411 of the oil supply pipe 41. Since the supply amount of the water W supplied into the supply pipe 31 is larger, the oil E discharged from the discharge port 411 of the oil supply pipe 41 is caused by the momentum of the water W supplied into the water supply pipe 31. While being transported in the direction opposite to the discharge port 411, it is fed into the passage 431 (see FIG. 2).

Water W and oil E fed into the passage 431 are transferred toward the arrangement region D3 set in the water supply pipe 31 along the passage 431 while being mixed with each other in the passage 431. The ultrasonic vibration generated by the ultrasonic vibrator 60 is applied to the water W and the oil E in the mixed fuel WE transferred through the passage 431 to reduce the particles of the water W and the oil E in the mixed fuel WE. (See FIG. 2).

Accordingly, a sufficient transfer distance and transfer time for mixing the water W and the oil E can be secured, and the oil E is formed in the arrangement region D3 of the water supply pipe 31 without being sufficiently mixed with the water W. It is possible to prevent discharge from the plurality of holes 311.

A mixed fuel WE in which water W and oil E are mixed is discharged in a radially outward direction from a plurality of holes 311 formed in the arrangement region D3 of the water supply pipe 31, and the water supply pipe 31, mesh pipe 50, The liquid is temporarily stored in the liquid storage part 430 formed between the opposing surfaces (see FIG. 2).

When the mixed fuel WE temporarily stored in the liquid storage unit 430 passes through the mesh pipe 50 surrounding the water supply pipe 31, the mixed fuel WE passes through the water W and the oil E in the mixed fuel WE. After the particles are made small, the liquid is stored in the liquid storage region D2 in the mixing chamber 21.

The ultrasonic vibration generated by the ultrasonic vibrator 60 is applied to the mixed fuel WE stored in the liquid storage region D2 in the mixing chamber 21, and the particles of water W and oil E in the mixed fuel WE are further reduced. At the same time, the mixed fuel WE stored in the liquid storage region D2 in the mixing chamber 21 is actively stirred by the stirring device 70 (see FIG. 2).

Accordingly, the water W and the oil E in the mixed fuel WE are reduced to fine particles by the synergistic action of the penetration of the mesh tube 50, the ultrasonic vibration of the ultrasonic vibrator 60, and the stirring of the stirring device 70. In addition, the water W and the oil E can be mixed in a uniform state.

As a result, it is difficult to separate the mixed water W and oil E, and the uniform mixed fuel WE in which the water W and oil E are easily burned and mixed in a stable state is supplied to the combustion apparatus 10 shown in FIG. it can. The mixed fuel WE in which the water W and the oil E are mixed can be used as the fuel of the existing combustion apparatus 10 and can be completely burned.

Moreover, since the oil supply pipe 41 that supplies the oil E and the passage 431 that mixes while transferring the water W and the oil E are separated, the mixed fuel WE that is being transferred through the passage 431 can be It is possible to reliably prevent the oil E from being mixed from the middle.
Thereby, since the ratio of the water W and the oil E to be mixed in the passage 431 can be kept constant, the uniform mixed fuel WE in which the water W and the oil E are easily mixed and more stably mixed is obtained. You can definitely get it.

Furthermore, since the mixed fuel WE stored in the liquid storage region D2 in the mixing chamber 21 is stirred by the stirring device 70, the water W and the oil E in the mixed fuel WE can be mixed in a more uniform state. .
Thereby, the uniform mixed fuel WE in which the water W and the oil E are easily combusted and mixed in a more stable state can be obtained more reliably.

Furthermore, the mixing ratio may be variably adjusted so that the mixing amount of the water W supplied from the water supply source 30 is larger than the mixing amount of the oil E supplied from the oil supply source 40. The mixed fuel WE contained can be completely burned by the existing combustion apparatus 10 as fuel.

Hereinafter, other examples of the fuel mixing apparatus 20 described above will be described. In this description, parts that are the same as or equivalent to those in the above configuration are denoted by the same reference numerals, and detailed description thereof is omitted.

(Example 2)
In the first embodiment, the example in which the oil supply pipe 41 is inserted to reach the central portion in the longitudinal direction L of the water supply pipe 31 has been described. However, in the second embodiment, as illustrated in FIG. Next, the fuel mixing device 20 inserted through a length that passes through the central portion in the longitudinal direction L of the water supply pipe 31 and reaches the portion bent upward on one end side will be described.
FIG. 3 is an enlarged cross-sectional view of the fuel mixing device 20 of the second embodiment.

In the fuel mixing device 20 of the second embodiment, the arrangement region D4 in which the hole 311 is arranged is set in a wide range including the other end side in the longitudinal direction L of the water supply pipe 31 and the central portion. The other end side of the oil supply pipe 41 passes through the central portion in the longitudinal direction L of the water supply pipe 31 and is inserted so as to reach a part bent upward on the one end side (the left part shown in FIG. 3). Yes.

Thereby, compared with the channel | path 431 of Example 1, the channel | path 432 of Example 2 is longer, and it can ensure more reliably the transfer distance and transfer time sufficient to mix the water W and the oil E. it can.
Therefore, the water W and the oil E can be reliably discharged in the radially outward direction from the many holes 311 formed in the arrangement region D4 of the water supply pipe 31 while mixing the water W and the oil E more uniformly in the passage 432. .

As a result, the water W and the oil E are more easily combusted and stable when the water W and the oil E are mixed in the passage 432 of the second embodiment than in the passage 431 of the first embodiment. Therefore, the effects and effects added to Example 1 can be achieved.

In addition, the arrangement area D4 of the second embodiment is wider than the arrangement area D3 of the first embodiment, and the number of holes 311 arranged in the arrangement area D3 is larger than the number of holes 311 arranged in the arrangement area D4. The number of arrangements can be increased.

As a result, the mixed fuel WE in which the water W and the oil E are mixed can be efficiently discharged in the radially outward direction from the numerous holes 311 formed in the arrangement region D4. And oil E can be efficiently mixed, and a large amount of the mixed fuel WE can be supplied to the combustion apparatus 10 shown in FIG.

(Example 3)
In the first embodiment, the example in which the water W and the oil E are mixed while being transferred has been described. However, in the third embodiment, as shown in FIG. 4, the convex shape in which the water W and the oil E are formed in the passage 431. The fuel mixing device 20 that gets over the stirring protrusion 433 and mixes the fuel actively will be described.
FIG. 4 is an enlarged cross-sectional view of the fuel mixing device 20 of the third embodiment.

In the fuel mixing device 20 of the third embodiment, convex stirring protrusions 433 formed in a substantially hemispherical cross section are staggered with respect to the inner peripheral surface of the water supply pipe 31 and the outer peripheral surface of the oil supply pipe 41. A plurality of them are arranged in the longitudinal direction L at a predetermined interval.

Specifically, the water W supplied into the water supply pipe 31 and the oil E discharged from the discharge port 411 of the oil supply pipe 41 are formed along a passage 431 formed between the opposing surfaces of the supply pipes 31 and 41. Then, the plurality of agitation protrusions 433 formed on the opposing surfaces of the supply pipes 31 and 41 are moved over and mixed positively.
That is, since the mixed fuel WE in which the water W and the oil E are mixed is transferred while meandering in the radial direction and the circumferential direction, the water W and the oil E can be uniformly mixed (see FIG. 4).

Thereby, rather than mixing while transferring the water W and the oil E, the water W and the oil E can be mixed more positively in a stable state in which the water W and the oil E are easily combusted.
As a result, the effects and effects added to Example 1 can be achieved.

In addition, when the plurality of stirring protrusions 433 are moved over, the ultrasonic vibration generated by the ultrasonic vibrator 60 is applied so that the water W and the oil E in the mixed fuel WE transferred in the passage 430 are finer. Therefore, the water W and the oil E can be mixed in a more uniform state.
In addition, you may combine the channel | path 432 of Example 2, and the stirring protrusion 433 of Example 3, and can mix the water W and the oil E efficiently in a more uniform state.

However, in the fourth embodiment, as illustrated in FIG. The fuel mixing device 20 disposed on the outer surface of the central portion in the direction L will be described.
FIG. 5 is an enlarged cross-sectional view of the fuel mixing device 20 of the fourth embodiment.

In the fuel mixing device 20 of the fourth embodiment, the ultrasonic transducer 61 that is smaller than the ultrasonic transducer 60 of the first embodiment is not clogged with respect to the outer surface of the central portion in the longitudinal direction L of the mesh tube 50. While being mounted, the water supply pipe 31 is arranged so as to avoid the arrangement region D3 set.

Specifically, the ultrasonic vibration generated by the ultrasonic vibrator 61 is a mixture fuel WE in which water W and oil E discharged from the hole 311 of the water supply pipe 31 are mixed, and the water supply pipe 31 and mesh pipe. It is applied to the mixed fuel WE stored in the liquid storage section 430 between 50 and 50.

As a result, the water W and the oil E in the mixed fuel WE are reduced to finer particles by the synergistic action of the permeation of the mesh tube 50 and the ultrasonic vibrations of the ultrasonic vibrators 60 and 61, and the water W And oil E can be mixed in a uniform state.
As a result, the effects and effects added to Example 1 can be achieved.
In addition, when attaching the ultrasonic transducer | vibrator 61 to the mesh pipe | tube 50 of Example 3, it arrange | positions avoiding the arrangement | positioning area | region D4 set to the water supply pipe | tube 31. FIG.

(Example 5)
In Example 1, although the example which surrounded the outer peripheral surface full length of the water supply pipe 31 with the mesh pipe | tube 50 was demonstrated, in Example 5, only the outer peripheral surface of arrangement | positioning area | region D3 of the water supply pipe 31 is shown, as shown in FIG. The fuel mixing device 20 surrounded by the mesh tube 50 will be described.
FIG. 6 is an enlarged sectional view of the fuel mixing device 20 of the fifth embodiment.

In the fuel mixing device 20 of the fifth embodiment, the outer peripheral surface of the arrangement region D3 of the water supply pipe 31 is surrounded by the mesh tube 50, and the outer peripheral surface other than the arrangement region D3 of the water supply pipe 31 is exposed. The area surrounded by the mesh tube 50 is smaller than that of the entire outer peripheral surface of the tube 31 surrounded by the mesh tube 50, and the cost required for manufacturing the fuel mixing device 20 can be reduced.

Moreover, the water W and the oil E can be easily combusted and mixed in a more stable and uniform state while maintaining the action and effect when the mesh tube 50 of Example 1 is infiltrated. As a result, the effects and effects added to Example 1 can be achieved.
