FIG. 1 is a schematic perspective view of the device 1, and FIGS. 2 and 3 are cross-sectional views thereof. Note that FIG. 2 is a cross-sectional view taken in a plane perpendicular to the extending direction of the rotating shaft of the combustion material conveying section 2, and FIG. 3 is a cross-sectional view taken in a plane parallel to the extending direction of the rotating shaft. . Note that although a hot water supply device is shown here as an example, as mentioned above, it is also possible to use hot air instead of hot water, and this hot fluid supply device is not limited to only hot water.

As shown in these figures, the present device 1 is a hot water supply device that includes a combustible material transport section 2 that transports a combustible material M, and a carbonization combustion section 3 that burns and carbonizes the combustible material M. The carbonization combustion section 3 includes an outer wall member 31 that covers the upper part of the combustible material transport section 2, and the carbonization combustion section 3 further includes a fluid pipe 4 that passes through the outer wall member 31 and passes through the inside 32 of the outer wall member. provided.

Further, the present device 1 further includes a roof member 33 above the outer wall member 31. Thereby, the combustion material M can be carbonized while creating an appropriate oxygen-deficient state. Further, this roof member 33 may be provided with a chimney member 34 for discharging smoke and the like.

Moreover, the combustion material conveyance section 2 and the carbonization combustion section 3 are provided with a plurality of support legs 35 for supporting them from the ground surface. This makes it possible to separate the combustible material conveyance section 2 and the carbonization combustion section 3 from the ground surface, allowing stable installation even on somewhat uneven ground.

In addition, in the carbonization combustion section 3 of the present apparatus 1, it is preferable to have a metal mesh material 36 above the combustion material transport section 2 inside the outer wall member 31 that covers the combustion material transport section 2. By providing the metal mesh material 36, it is possible to remove soot, smoke, etc. that roll up when the combustible material M burns, and to control so that a large amount of soot, smoke, etc. is not discharged from the upper roof member 33 to the outside. It becomes possible.

Further, the combustion material transporting section 2 of the present device 1 is a member for transporting the combustion material M in at least one direction, and is arranged so as to penetrate the outer wall member 31. The combustion material conveying section 2 includes, but is not limited to, a rotating shaft 21, a spiral blade member 22 disposed around the rotating shaft 21, and a cover 23 that covers the rotating shaft 21 and the blade member 22. Preferably, the device is configured to include the following. The rotating shaft 21 and the blade member 22 are a so-called screw.

Further, the rotating shaft 21 is connected to a rotating mechanism 24 such as a motor, and is rotatable. By doing so, the combustion material conveying section 2 of the present device 1 injects the combustion material M into the gap between the blade members 22, rotates the rotating shaft 21 and the blade member 22, and efficiently stirs the combustion material M. It is possible to stably transport the material in a desired direction. Of course, it is preferable that the cover 23 is provided with an inlet 2331 near one end for injecting the combustible material M, and an outlet 2331 for discharging the combustible material (charcoal) that has been burned and carbonized at the other end. Preferably, an outlet 2321 is provided. Furthermore, as is clear from the drawings and the description of this specification, the upper part of the combustible material conveying section 2 is open within the outer wall member interior 32 and is connected to the internal space of the carbonization combustion section 3.

Further, as is clear from the above description, the cover 23 of the combustion material conveying section 2 includes a side cover 231 that covers both sides of the blade member 22, a bottom cover 232 that covers the bottom surface, and a top cover 233 that covers the top surface. There is. However, the top cover 233 is removed inside the outer wall member 31. This makes it possible to open only the upper part of the outer wall member 31 and efficiently transport the combustible material M without leaking it. Further, as described above, it is preferable that the upper surface cover 233 be provided on the portions protruding from the carbonization combustion section 3 (the front section and the rear section) and outside the outer wall member 32. This can prevent unnecessary impurities from being mixed in. Note that the input port 2331 for inputting the combustion material M is preferably provided in the top cover. Note that it is convenient to provide the exhaust port 2321 for discharging the carbonized combustion material M in the bottom cover 232.

The combustible material M in the present device 1 is not particularly limited as long as it can be charged into the combustible material transport section 2 and combusted and carbonized while being transported, but rice husks and rice straw may be used. Although it is possible to use rice husk, rice husk is more preferable.

Furthermore, it is preferable that the combustible material transport section 2 is provided with an ignition port 2332 for igniting the combustible material M at a stage upstream of and near the carbonization combustion section 3. More specifically, an opening is provided in the top cover 233. It is preferable to form the ignition port 2332 and use this as the ignition port 2332. A user can ignite the combustion material M at this ignition port 2332 using an ignition device (not shown) such as a burner to start combustion. Of course, the structure is not limited to this as long as the combustion material M can be sufficiently burned in the carbonization combustion section 3.

In addition, in the present apparatus 1, it is also preferable to provide a blower 25 for supplying air into the combustion material transport section 2. By providing the blower 25, it is possible to also supply air and stabilize combustion.

Further, as described above, the carbonization combustion section 3 in the present device 1 is for burning and carbonizing the combustion material M, and is provided with the outer wall member 31 as described above.

Further, as described above, the carbonization combustion section 3 of the present apparatus 1 is provided with the fluid pipe 4 that passes through the outer wall member 31 and passes into the inner wall member 32.

Further, the fluid piping 4 of the present device 1 is a hollow cylindrical member, and by passing fluid through the inside, heat during combustion of the combustion material M can be transferred to the fluid and turned into a thermal fluid. It becomes possible. Further, for this reason, it is natural that the material of the fluid piping 4 is preferably metal from the viewpoint of heat conduction. The thermal fluid may be hot air or hot water, as described above.

Further, it is preferable that the fluid piping 4 of the present device 1 has a screw 41 inserted therein. By providing the screw 41, it is possible to form a spiral flow path, increase the chances of the fluid coming into contact with the outer periphery of the fluid piping 4, and improve thermal efficiency. FIG. 4 shows an outline of the screw 41. Incidentally, the screw 41 can adopt the same configuration as the above-mentioned combustible material conveying section 2, and may include, for example, a rotating shaft 21 and a blade member 22 arranged spirally along the rotating shaft 21. preferable.

Note that this screw 41 is rotatable by being connected to a rotating mechanism 24 such as a motor, similar to the fuel conveyance section 2 described above, so that the flow rate of the thermal fluid can be reliably controlled. Since the main point of view is to increase the chances of fluid contact with each other, a configuration may be adopted in which the rotation mechanism 24 is not provided and the rotation is not performed. In this case, it is also preferable that the vane member 22 be fixed within the fluid pipe 4.

Further, when the blade member 22 is fixed inside the fluid piping 4, from the viewpoint of ensuring the flow rate of the fluid, it is preferable to remove the rotating shaft 21 and join the blade member 22 to the inner surface of the fluid piping 4. . By doing so, it is possible to provide a spiral blade with a through hole, and the blade member 22 effectively increases the chance of contact between the fluid and the fluid piping 4 while ensuring the flow rate without providing any particular power. It becomes possible to secure the

Further, in the present device 1, it is also preferable to provide a plurality of fluid piping 4. By providing a plurality of them, it becomes possible to increase the amount of thermal fluid to be supplied. In particular, the advantage is that it becomes possible to supply different fluids, in particular both hot water and hot air, independently.

Further, in the case where a plurality of fluid pipes 4 are provided in the present device 1, it is preferable to provide a collective pipe 42 that brings together the plurality of fluid pipes 4 on the outside or inside of the outer wall member 31. By doing so, input and output can be supplied as a single unit. More specifically, even if the amount of fluid is the same, by branching into a plurality of thin fluid pipes 4, the surface area of each can be increased and the efficiency of heat exchange can be improved. By using one pipe, there is an advantage that the conveyance flow rate can be increased. An example of the collective piping 42 is shown in FIG.

Further, in the present device 1, although not limited to this, the plurality of fluid pipes 4 may meander inside the outer wall member 32. An image of this case is shown in FIG. The meandering may be meandering by reciprocating, but it may also be meandering in a direction perpendicular to the traveling direction (extending direction of the rotation axis of the combustion member conveying section) without reciprocating. By doing so, the contact distance between the thermal fluid and the heat is increased, and more efficient heat exchange becomes possible.

(thermal fluid supply method)
Further, the present device 1 can provide a thermal fluid supply method (hereinafter referred to as “the present method”) by operating. Specifically, the method includes (S1) transporting the combustion material to the carbonization combustion section, (S2) burning and carbonizing the combustion material inside the carbonization combustion section, and (S3) passing the combustion material into the carbonization combustion section. heating the fluid in the fluid piping.

As described above, this method includes the step of (S1) transporting the combustion material to the carbonization combustion section, which includes charging the combustion material from the input port and driving the rotation mechanism in the combustion material transportation section. This means that the combustion material is conveyed in the direction in which the rotating shaft extends.

On the other hand, by igniting the combustible material with an ignition device or the like while transporting the combustible material, the combustible material is combusted inside the carbonization combustion section, and the combustible material is carbonized. This becomes the step (S2) of burning and carbonizing the combustion material inside the carbonization combustion section.

At this time, by supplying a fluid such as wind or water into the fluid piping, it becomes possible to turn this wind or water into hot air or warm air, and (S3) the fluid passed into the carbonization combustion part. This allows for a step of heating the fluid within the pipe.

As described above, with this device, it becomes possible to transport and carbonize the combustion material, and to supply a thermal fluid by utilizing the heat during carbonization more efficiently.

The present device has industrial applicability as a thermal fluid supply device.
