Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a device for automatically supplying solid fuel to a combustion device.

<Prior art> Conventionally, solid fuels such as coal, coke, and charcoal used in various combustion devices are normally consumed in fixed amounts such as 10 [Kg] and 15 [Kg], except when large quantities are consumed. Sold in bags made of paper, cloth, etc.
Consumers scoop the required amount from the bag as needed.
It is taken out with clips, etc. and supplied to the combustion device, and at the beginning of combustion, it is ignited directly or by kindling to ignite the solid fuel and perform the first combustion. It is necessary to gradually replenish the fuel before the spark goes out. At this time, replenishing the fuel had to be done manually while measuring the amount, which was very time-consuming and often soiled hands and clothes. Additionally, measuring the amount of fuel by eye makes the amount supplied uneven and makes the next refill time uncertain, so if you want to do it accurately, you must always have a monitoring device such as a meter installed. It was impossible.

Therefore, in order to automatically supply the required amount of fuel when replenishment is required, conventional solid fuel was packed in paper bags in the required amount for combustion and supplied to the combustion device when continuous combustion was required. There were some shortcomings.

Also, Utility Model No. 52-68439, No. 56-139590,
Bagged fuel and ignited charcoal are disclosed in Utility Model Publication No. 57-9845, etc., but the former two are mainly alcohol fuels for portable and tabletop use, and the bags are simply portable packaging bags, and after combustion, It is also a material that remains flammable.
In addition, igniting charcoal is used in combination with briquettes, pea charcoal, charcoal, etc., and is individually covered with a hydrophobic resin film, or packed in multiple bags, but it is not a type that burns the entire bag containing multiple pieces. do not have. or,~
There is no disclosure of any means for periodically introducing fuel into the combustion device by an automatic supply device. Japanese Utility Model Publication No. 56-50257 is known as an automatic solid fuel supply device, and this device stores rod-shaped solid fuel (not in bags) horizontally in a hopper, stacks them in multiple tiers, and stores the solid fuel in the bottom tier. The fuel is pushed out into the combustion chamber by a fuel pushing rod, and the fuel is pushed down into the combustion chamber.The operation of the fuel pushing rod is due to the weight of the fuel supported on the tray in the combustion chamber. floats up, and the arm connected to it, the connecting rod, the spring, and the fuel pushing rod operate.

Therefore, the operation is completely mechanical, each member is connected by multiple joints, and it is a bulky mechanism.Furthermore, fuel falls from above each time a cylinder is burned, so there is no need to contact the joints at the joints. The weight and vibrations are transmitted quickly, causing damage to various parts.Furthermore, in order to push out fuel one by one, shielding plates and shielding plates are attached to block the next fuel, which further causes failures in the interlocking mechanism and rotation operation. is also likely to occur.
It is also completely unsuitable for extruding irregularly shaped groups of fuel in flexible bags, and no mechanism suitable for this is shown.

<Purpose of the invention> The present invention focuses on the above-mentioned problems, stores the required amount of solid fuel in a synthetic resin bag, automatically supplies it to the combustion device when necessary, and leaves no ash content in the burned bag. The purpose of the present invention is to provide a device that does the following.

<Configuration of the Invention> The solid fuel supply device of the present invention includes a support section that supports and stores solid fuel for replenishment, and a control section that is controlled by a sensor and a timer and supplies solid fuel when required. be done. In addition, the fuel storage bag is made of polymer film, and it was discovered that combustion ash is not generated due to the polymer.

<Example> Hereinafter, it will be explained in detail using examples.

The solid fuel supply device 3 includes a support part 5 that supports the solid fuel 4 packed in bags, a hook 6 for suspending and holding a plurality of solid fuels 4 packed in plastic bags, and hooks 6 for hanging and holding a plurality of solid fuels 4 packed in plastic bags. The guide groove 7 that guides the packed solid fuel 4 to the fuel input port 2 and the vent 8 of the solid fuel combustion device 1 are opened and closed at predetermined intervals or at a predetermined temperature by a timer or sensor, and the bagged solid fuel 4 is dropped. Control device 9 for controlling operation
and an opening/closing door 10 of the support section 5. Further, 11 is a mounting table for height adjustment.

FIG. 5 shows a flow chart of the operation of the solid fuel supply device of the present invention. When using the solid fuel combustion device 1, first open the lid 1a of the solid fuel combustion device 1, put in the ignition material and ignite it, then fill it with bare solid fuel and start the first combustion. Do the following.
Further, at this time, if a temperature sustaining type ignition device such as electricity or gas is used as the ignition means, the bagged solid fuel may be filled from the beginning. after that,
When the first combustion approaches the end, a timer built into the control device 9 recognizes a preset time, or a temperature sensing element detects that the temperature inside the solid fuel combustion device 1 has fallen below a predetermined temperature. The control device 9 detects this using a sensor consisting of a sensor, and sends a control signal to the opening/closing device 12 to open the vent 8 for a predetermined period of time. Next, the control device 9 energizes the latch 6 ₁ closest to the fuel inlet 2 among the latches 6 , heats the tip of the latch 6 ₁ with a built-in heater, and heats the solid fuel 4 . The sealing hole of the plastic bag filled with is broken and the bag is dropped into the guide inclined groove 7. The fallen bagged solid fuel slides down inside the guide inclined groove 7 and is replenished into the solid fuel combustion device 1 through the fuel input port 2. From next time onwards, the previous operation is repeated at predetermined time intervals or at predetermined temperature intervals, and the bagged solid fuel 4 suspended from each latch 6 ₁ , 6 ₂ , 6 ₃ . . . is supplied in sequence. be done. When the bagged solid fuel 4 stored in the support section 5 runs out, the opening/closing door 10 can be opened to replenish the fuel and the control device 9 can be reset. In addition, here, the latch 6 is used to hold the bagged solid fuel 4, but other methods may be used, for example, as shown in FIG. Open and close the
The bagged solid fuel 4 placed on the opening/closing plate 13 is
Various methods can be considered, such as a method of sequentially supplying the bag, a method of mechanically cutting off the hooking part of the bag, and a method of forming a continuous bag and cutting the connecting part, but the gist of the present invention is This function is achieved because the bagged solid fuel is sequentially supplied in a predetermined amount at predetermined time intervals or at predetermined temperature intervals according to the control signal from the control device 9, and is then combusted. You can use other methods if you have them. Here, FIG. 2 is a perspective view showing the solid fuel supply device of the present invention, and FIG.

As a combustion device that uses the device of the present invention, especially if the low distribution solid fuel combustion device of the invention of Japanese Patent Application No. 57-199246 is used, lignite, petroleum coke, molded coke, Calsaina coke, etc., which do not burn and leave no ash, can be used. Even if this low ash solid fuel is used continuously for a long time, very little ash remains and no pollution occurs, making it even more effective.

In addition, the plastic bag is cheaper than paper and does not produce ash, and unlike paper, it melts instantly, so there is no risk of extinguishing the spark, and there is no risk of blocking ventilation even without a rooster.

<Effects of the Invention> As described above, the solid fuel supply device of the present invention has the following effects:
The combustion temperature or time is detected by a sensor or timer to supply the bagged solid fuel to the combustion device, and each bag is heated by its latching metal fittings according to a control signal, and the bag is melted or fused. Since it is difficult to supply irregularly shaped or flexible bags by mechanical interlocking or extrusion, it is possible to reliably and easily supply bags by unhooking the bag or opening the support by deforming and restoring the bag. A predetermined amount of bagged solid fuel can be automatically supplied at predetermined intervals, eliminating the need to constantly monitor and inspect combustion equipment for use in cold regions, heating greenhouses, etc., and ensuring stable supply and combustion. You can expect it.

By putting solid fuel in a plastic or other synthetic resin bag, it can be used not only in the equipment itself but also around the equipment.
