More specifically, the shooter 101 is formed of a bent or curved cylinder, and the side opening 101 b of the shooter 101 and the solid fuel inlet 14 of the combustion chamber 13 communicate with each other. In addition, a damper 102 that receives the solid fuel 7 supplied from the solid fuel storage and conveyance device 1 and feeds it into the hollow portion of the shooter 101 is provided at or near the upper opening 101 a of the shooter 101. Further, a solid fuel feed section 104 that receives the solid fuel 7 fed from the damper 102 and puts it into the combustion chamber 13 is installed at or near the side opening 101 b of the shooter 101.
Note that each of the damper 102 and the solid fuel feed unit 104 shown in FIG. 1 is configured to rotate with the pivot 103 and the pivot 105 provided in the hollow portion of the shooter 101 as the base axes.
In the solid fuel supply apparatus 100 according to the present embodiment, the upper opening 101 a of the shooter 101 is substantially the solid fuel inlet 14 of the combustion chamber 13.

Next, the detailed structure and operation mechanism of the solid fuel supply apparatus 100 according to the present embodiment will be described in detail with reference to FIG.
FIG. 2 is a cross-sectional view of a solid fuel supply apparatus according to an embodiment of the present invention. In addition, the same code | symbol is attached | subjected about the part same as what was described in FIG. 1, and the description about the structure is abbreviate | omitted.
As shown in FIG. 2, the damper 102 of the solid fuel supply apparatus 100 according to the embodiment is arranged in the vicinity of the upper opening 101 a of the shooter 101 and near the inner wall of the shooter 101, with the pivot 103 passing through the shooter 101 and horizontally. A flat support portion 102b that opens and closes the upper opening 101a of the shooter 101 is fixedly provided on the peripheral side surface of the pivot shaft 103 (including a substantially horizontal concept). Further, the upper surface of the support portion 102b of the damper 102 receives the rod-shaped solid fuel 7 supplied to the upper opening 101a of the shooter 101 while buffering it, and also causes the solid fuel to fall when the support portion 102b is tilted. A flat plate-like mounting portion 102a is provided.
Further, as shown in FIG. 2, in the solid fuel supply apparatus 100 according to the present embodiment, when the damper 102 is rotated to drop the solid fuel 7 into the shooter 101, the support portion 102b (and the placement portion 102a). ) Is used as a slide, the pivot 103 is disposed in the vicinity of the inner wall of the shooter 101 on the side away from the combustion facility 12.
Further, by placing the mounting portion 102a of the damper 102 at a position slightly behind the upper opening 101a of the shooter 101, the opening of the cylindrical body forming the upper opening 101a of the shooter 101 is allowed to drop the solid fuel 7 Can be used as a stopper to prevent
In addition, by providing the funnel-shaped guide portion 112 between the flat support portion 102b and the upper opening 101a of the shooter 101, hot air in the combustion chamber 13 escapes to the outside through the hollow portion of the shooter 101. Is preventing.

The damper 102 receives the solid fuel 7 supplied to the upper opening 101a of the shooter 101 on its upper surface and then rotates the pivot 103 clockwise as shown in FIG. The mounting portion 102a is tilted by rotating the pivot 103 about the base shaft (in the direction indicated by the symbol A in FIG. 2), and the rod-shaped solid fuel 7 placed on the placing portion 102a is moved into the shooter 101. The solid fuel is supplied to the solid fuel feeding unit 104 by being dropped.
At this time, the pivot 103 is rotated by the power transmitted from the first drive mechanism 106 via the power transmission unit 107.
As the power transmission unit 107 that operates the damper 102, for example, a combination of a piston 107a and an arm 107b can be used as shown in FIG.

In FIG. 2, the case where the pivot 103 is disposed in the vicinity of the upper opening 101a of the shooter 101 is described as an example, but there is no possibility that the solid fuel 7 dropped into the upper opening 101a jumps out to the outside due to the reaction. In this case, the pivot 103 may be disposed so as to be placed on the upper opening 101 a of the shooter 101.
In addition, the mounting portion 102a provided on the upper surface of the damper 102 is provided to smooth the feeding of the solid fuel 7 to the solid fuel feeding portion 104, which will be described later, and is solid even without the mounting portion 102a. When the solid fuel 7 can be smoothly supplied to the fuel feeding unit 104, the placement unit 102a is not necessarily provided.

Next, the solid fuel feed unit 104 disposed at or near the side opening 101b of the shooter 101 will be described. The solid fuel feed unit 104 is a facility that receives the rod-shaped solid fuel 7 supplied from the damper 102 and feeds it into the combustion chamber 13 of the combustion facility 12.
The solid fuel feed section 104 is fixed to the pivot 105 with an L-shaped cross section comprising a flat plate-shaped receiving section 104a and a stopper 104c that abuts the end of the receiving section 104a perpendicularly (including a substantially vertical concept). It has been done. In such a solid fuel feed section 104, each is arranged so that the extension direction of the corner of the above-mentioned L-shaped section matches the extension direction of the pivot 105 (including the concept of substantially matching).
Further, the stopper 104c in the solid fuel feeding unit 104 prevents the solid fuel 7 from dropping excessively from the receiving unit 104a when the rod-shaped solid fuel 7 supplied from the damper 102 is received by the receiving unit 104a. Is for.
In the solid fuel supply apparatus 100 according to the present embodiment, these are arranged so that the upper surface of the placement portion 102a of the rotated damper 102 and the upper surface of the receiving portion 104a of the solid fuel feed portion 104 form an obtuse angle. It is good to leave. In this case, the rod-shaped solid fuel 7 dropped from the damper 102 can be reliably received without being missed by the receiving portion 104 a of the solid fuel feeding portion 104.

Further, by tilting the upper surface of the receiving portion 104a so as to descend toward the pivot 105 instead of being horizontal, the extension direction of the rod-shaped solid fuel 7 on the receiving portion 104a coincides with the extension direction of the pivot 105. Can be held. That is, the rod-shaped solid fuel 7 that has fallen to the receiving portion 104a can be always held in a state of being brought close to the stopper 104c.
Thus, the state of the solid fuel 7 fed into the combustion chamber 13 by the solid fuel feed unit 104 is also constant by always making the direction of the rod-shaped solid fuel 7 held by the solid fuel feed unit 104 constant. Can be.

Further, the pivot 105 of the solid fuel feed unit 104 is rotated by a second drive mechanism 108 provided at the lower part of the shooter 101. More specifically, a power transmission unit 109 made of, for example, a power transmission chain or a belt is interposed between the drive shaft of the second drive mechanism 108 and the pivot 105, so that the second drive The power generated in the mechanism 108 is transmitted to the pivot 105 through the power transmission unit 109 to rotate the pivot 105.
In such a solid fuel supply apparatus 100 according to this embodiment, the pivot 105 is rotated clockwise on the paper surface of FIG. 2, so that the L-shaped cross section composed of the receiving portion 104 a and the stopper 104 c is formed on the pivot 105. It rotates clockwise with the central axis as the base axis (the direction indicated by symbol B in FIG. 2).
By this operation, the receiving portion 104a having the L-shaped cross section is turned upside down as shown by a broken line in FIG. 2, and the rod-shaped solid fuel 7 held on the receiving portion 104a is moved into the combustion chamber 13 ( In the direction indicated by symbol C in FIG.

At this time, the rod-shaped solid fuel 7 is dropped into the combustion chamber 13 so as to straddle the side opening 101b in a state where the axis of the solid fuel 7 is kept horizontal (including a substantially horizontal concept). The probability that the dropped solid fuel 7 is placed on the combustion bed 19 is extremely high.
Therefore, as shown in FIG. 4, it is possible to prevent the rod-shaped solid fuel 7 from being supplied in a state where it is leaned against the inner wall of the combustion chamber 13.
That is, by using the solid fuel supply device 100 according to the present embodiment, it is easy to make the axis of the rod-shaped solid fuel 7 reaching the combustion bed 19 of the combustion chamber 13 horizontal (including a substantially horizontal concept). Become.
Thereby, it is possible to prevent the combustion temperature in the combustion chamber 13 from being outside the desired range due to the non-constant arrangement of the rod-shaped solid fuel 7 in the combustion chamber 13.

In the case of the solid fuel combustion apparatus 11 according to the prior art shown in FIGS. 3 and 4, the rod-shaped solid fuel 7 is merely dropped by the damper 16 onto the slope-shaped guide plate 18.
For this reason, in the solid fuel combustion apparatus 11 according to the prior art, the solid fuel 7 may stay on the guide plate 18.
On the other hand, since the solid fuel supply device 100 according to the present embodiment includes the solid fuel feeding unit 104 in addition to the damper 102, the solid fuel 7 is reliably delivered to the combustion chamber 13 by a two-stage operation. Can do. Therefore, the solid fuel 7 does not stay in the shooter 101. Therefore, the solid fuel 7 can be reliably supplied to the combustion chamber 13 when necessary, and it becomes easy to maintain the combustion temperature of the combustion chamber 13 within a desired range.
In the solid fuel supply apparatus 100 according to the present embodiment, the damper 102 is tilted by rotating the pivot 103 around the pivot 103 in order to reliably deliver the rod-shaped solid fuel 7 supplied to the damper 102 to the combustion chamber 13. After that, it is necessary to rotate the solid fuel feed unit 104.

Further, in the solid fuel supply apparatus 100 according to the present embodiment, shielding for blocking hot air from the combustion chamber 13 at or near the side opening 101b that is a connection portion between the combustion chamber 13 of the combustion facility 12 and the shooter 101. You may provide the board 110 so that opening and closing is possible.
By providing this shielding plate 110, it is possible to prevent the hot air in the combustion chamber 13 from escaping from the shooter 101 to the outside, so that the heating efficiency by the combustion facility 12 can be improved.
As a driving mechanism for the shielding plate 110, for example, the shielding plate 110 is pivotally connected to the side opening 101b of the shooter 101 or the vicinity thereof via a rotation shaft 111, and the first and second driving mechanisms are provided. A drive mechanism other than 106 and 108 may be provided and opened and closed in accordance with the operation of the solid fuel feed unit 104. Alternatively, the shielding plate 110 may be opened and closed in conjunction with the solid fuel feed unit 104 using the power of the second drive mechanism 108 (not shown).

In addition, as a method for opening and closing the shielding plate 110 as described above, there are also the following methods.
For example, as shown in FIG. 2, a push-up portion 104b made of a fan-like flat plate is fixed to the outer periphery of the pivot 105, and when the pivot 105 rotates clockwise, the push-up portion 104b is pivoted. The shield plate 110 may be configured to be pushed up by turning the shaft 105 around the base shaft so that the arcuate outer edge of the push-up portion 104b is brought into contact with the shield plate 110.
In this case, when the pivot 105 rotates counterclockwise, the contact between the fan-shaped push-up part 104b and the shielding plate 110 is released, and the shielding plate 110 returns to the position before being pushed up by its own weight. That is, the side opening 101 b of the shooter 101 is shielded by the shielding plate 110.
As described above, it is not necessary to separately provide a drive mechanism for opening and closing the shielding plate 110 by opening and closing the shielding plate 110 in conjunction with the rotation operation of the solid fuel feed unit 104. Therefore, the configuration of the solid fuel supply apparatus 100 according to the present embodiment can be simplified. In this case, power (such as electric power) for opening and closing the shielding plate 110 can be saved.
Further, a shield 114 may be provided below the solid fuel feed unit 104 so as to partition the space on the lower surface side of the receiving unit 104a. In this case, the shield 114 and the shield plate 110 cooperate to prevent hot air in the combustion chamber 13 from flowing into the shooter 101. Thereby, the heating efficiency by the combustion facility 12 can be further improved.

Furthermore, in the solid fuel supply apparatus 100 according to the present embodiment, the damper 102 may be provided with a sensor 113 for detecting the open / closed state of the damper 102.
In this case, for example, the first driving mechanism 106 and the second driving mechanism are used by using a control unit (not shown) so that the solid fuel feeding unit 104 rotates after a desired time after the rotating operation of the damper 102 is detected. By controlling the drive of 108, the rod-shaped solid fuel 7 can be smoothly and reliably supplied to the combustion chamber 13.

Here, returning to FIG. 1 again, the solid fuel combustion apparatus 115 provided with the solid fuel supply apparatus 100 according to the present embodiment as described above will be described.
