The mixture begins to separate immediately after mixing, and when it reaches the burner, the separation proceeds and causes incomplete combustion. In the mixing apparatus disclosed in Patent Literature 1, the mixed state of the mixture after being discharged may be unstable and separated, and the mixture is discharged from the discharge port in an insufficiently mixed state, and the combustion of the mixture is not stable. There are challenges.

Therefore, an object of the present invention is to provide a mixing apparatus capable of increasing the mixing state (closeness) between a plurality of materials to be mixed and making a good mixing state.

In order to achieve the above object, the mixing apparatus of the present invention has the following configuration. That is, the present invention is a mixing device for mixing a plurality of materials to increase the closeness between the materials, and has a heating means, heating a plurality of supplied materials to vaporize, and rotating A stirrer that is connected to a shaft and has a rotating blade that is rotatably arranged around the rotating shaft, is heated by the heating unit, is supplied with a plurality of vaporized materials, and is stirred by the rotating blade And a mixed material is produced. According to this configuration, it is possible to enhance the mixing action of a plurality of materials to be mixed and to generate a mixed material in a good mixed state.

In the present invention, the internal space of the heating unit may be heated to a temperature equal to or higher than the boiling point of the supplied material. According to this, since the material passes through the heating unit heated to the boiling point of the supplied material or more, the material is vaporized.

In the present invention, the material may be water and heavy oil A. According to this, even water and A heavy oil can be mixed uniformly, and the resulting mixed material is difficult to re-separate, and a stable flame can be obtained when burned.

According to the configuration of the mixing apparatus of the present invention, it is possible to increase the mixing state (closeness) between a plurality of materials to be mixed and to achieve a good mixing state.

It is a figure which shows schematic structure of the mixing apparatus concerning embodiment of this invention.

Hereinafter, the mixing apparatus 10 of the present invention will be described based on the embodiments.

FIG. 1 shows a schematic diagram of a mixing apparatus 10 according to the present embodiment. The mixing apparatus 10 concerning this Embodiment has the heating part 20 and the stirring part 40, as shown in FIG. The heating unit 20 includes a heating unit 24, and a plurality of materials supplied from the material supply port 22 are heated by the heating unit 20 and vaporized in the heating unit 20. The heating unit 20 and the stirring unit 40 communicate with each other through the communication unit 30, and a plurality of materials heated and vaporized by the heating unit 20 pass through the communication unit 30 and are supplied to the stirring unit 40. The stirring unit 40 includes a rotating blade 44 that is connected to a rotating shaft 42 and is disposed so as to be rotatable about the rotating shaft 42. The plurality of materials supplied from the heating unit 20 are agitated by the rotary blades 44 together with the air flowing in from the air inlet 46, and are fed forward while being mixed, and the mixed material is discharged from the discharge port 48. In the stirrer 40, since the plurality of materials that are heated and vaporized are uniformly mixed, the closeness is increased, and the flame is stabilized even if the generated mixed material is burned. In addition, the arrow in a heating part 20, the communication part 30, and the stirring part 40 in a figure, and the arrow of a dotted line show the flow of the substance in each inside.

The inside of the heating unit 20 is heated to a temperature close to or higher than the boiling point of the supplied material depending on the supplied material. The heating means 24 can be heated to a temperature close to or higher than the boiling point of the supplied material, and is arranged in the heating unit 20 and has a structure in which there is a space through which the material can pass. Although the heating means 24 shown in FIG. 1 is one, it is also possible to provide a plurality of heating means 24, which are connected to each other. The supplied material is sufficiently heated and vaporized while passing around the heating means 24.

When the supplied material is heated around the heating means 24, the vaporized material is added to the force of a plurality of materials supplied from the material supply port 22 and flows into the communication unit 30. The plurality of materials before passing through the communication part 30 do not necessarily have the same vaporization temperature, so that there are some materials in which the vaporized materials are separated and others in a mixed state. In order to bring this separated vaporized product into a good mixed state, it is sent to the stirring unit 40 and stirred by the stirring unit 40. The communication part 30 should just be a position and a structure which can pass the vaporized vapor, and in the mixing apparatus 10 of this embodiment, the communication part 30 is provided in the lower part of the stirring part 40. FIG.

The stirring unit 40 is provided with an air inlet 46 so that air is sent from outside the mixing device 10 into the stirring unit 40, and the air inlet 46 is arranged in the stirring unit 40 in an arrangement facing the communication unit 30. ing. Furthermore, a blower (not shown) may be provided in the air inlet 46. The vaporized material rises in the stirring unit 40 together with the air sent from the blower due to the pushing force of the vapor flowing into the stirring unit 40 and the high temperature of the vapor sent from the communication unit 30. It becomes the flow to do. And the discharge outlet 48 should just be located in the upper part of a side surface like FIG. In FIG. 1, the rotating shaft 42 is disposed so as to stand upright in the stirring unit 40, and each rotating blade 44 connected to the rotating shaft 42 rotates around the rotating shaft 42. However, the rotating shaft 42 is not necessarily upright, and the rotating shaft 42 may be inclined with respect to the horizontal plane so that the vaporized substance rises in the stirring unit 40 and moves toward the discharge port 48.

As shown in FIG. 1, the rotary blade 44 is connected to a plurality of locations of the rotary shaft 42. Moreover, the internal space of the stirring unit 40 is divided into a plurality of mixing chambers. FIG. 1 shows an example in which the internal space of the stirring unit 40 is divided into three mixing chambers. The mixing chambers are a first mixing chamber 50, a second mixing chamber 52, and a third mixing chamber 54, respectively. Above the first mixing chamber 50, there is a second mixing chamber 52, and above the second mixing chamber 52, there is a third mixing chamber 54, which are in communication with each other. First, the vaporized material flowing in from the communication part 30 enters the first mixing chamber 50, and then the vaporized material flows upward in the order of the first mixing chamber 50, the second mixing chamber 52, and the third mixing chamber 54. Regarding the rotary blades, the whole blade in the stirring unit 40 is referred to as the rotary blade 44, the one in the first mixing chamber 50 is the rotary blade 60, the one in the second mixing chamber 52 is the rotary blade 62, the second one. Those in the three mixing chambers 54 are distinguished as rotating blades 64. By the rotary blades 60 provided in the first mixing chamber 50 and the rotary blades 62 provided in the second mixing chamber 52, the vaporized material is conveyed while being stirred, and a mixed material in a good mixed state can be generated. The mixed material can be generated by the rotating blades 64 provided in the third mixing chamber 54 and the mixed material sufficiently mixed can be sent to the discharge port 48. Each room has a different size, the first mixing chamber 50 being the largest, and then the second mixing chamber 52 being the largest. Although not illustrated, the outer shape of the stirring unit 40 may be a cone shape or a truncated cone shape that decreases upward, and the inner space of the stirring unit 40 with respect to the direction along the flow path of the airflow. The cross-sectional area becomes smaller.

The size of the rotary blade 44 and the number of blades are different. In the stirring unit 40 shown in FIG. 1, the first mixing chamber 50 has three rotary blades 60 with six blades, and the second mixing chamber 52 has one rotary blade 62 with eight blades. There are groups. The rotating blades 62 in the second mixing chamber 52 have smaller blades and more blades than the rotating blades 60 in the first mixing chamber 50. The rotary blade 60 of the first mixing chamber 50 and the rotary blade 62 of the second mixing chamber 52 are connected to the outer peripheral surface of the rotary shaft 42. The uppermost third mixing chamber 54 is provided with one rotary blade 64 at the tip of the rotary shaft 42. By such a rotary blade 44, the mixed material containing the mixed gas is sent to the discharge port 48 while mixing. A plurality of rotary blades 44 are provided, and the size of the rotary blades 44 is reduced upward so as to increase the number of the rotary blades 44, whereby vaporized substances can be mixed more uniformly and finely. Since the obtained mixed material is difficult to separate and stable, a stable flame can be obtained by discharging from the discharge port 48 and igniting. In the stirring unit 40, the vaporized material flowing in from the communication unit 30 and a part of the stirred mixed gas may be aggregated, and a mixed material containing the mixed gas is generated.

The power of the rotating blades 44 and the rotating shaft 42 is the force that a plurality of materials supplied from the material supply port 22 flows in, that is, the force and the air flow that the vaporized material vaporized in the heating unit 20 flows into the stirring unit 40. This is due to the force of air flowing in from the inlet 46. For this reason, the rotary blade 44 and the rotary shaft 42 rotate naturally. Along with this, there is also added by the rising vapor of the warmed vapor.

In addition, the material supplied to the heating unit 20 may be either solid or liquid, and at least one material may be solid or liquid, and the state of other materials may be different. However, the material supplied to the heating unit 20 is vaporized when heated by the heating unit 20, and at least one of the materials becomes fuel. The heating temperature by the heating means 24 is 280 ° C. or higher, and can be raised to a temperature at which the supplied material is hard to be carbonized, more preferably 300 to 400 ° C. The heating temperature is appropriately changed according to the supplied material. As an example of the plurality of materials to be supplied, water and A heavy oil can be cited. In this case, the heating means 24 heats the material to a boiling point higher than the boiling point of the A heavy oil having the highest boiling point among the supplied materials.

A plurality of material supply ports 22 of the heating unit 20 may be provided, or another material supply port 22 may be provided for each material. In addition, a mixing nozzle may be provided in front of the material supply port 22 and a mixture of a plurality of materials may be supplied to the material supply port 22.

A nozzle may be provided at the discharge port 48, and the mixed material may be jetted and ignited to emit a flame.
