Abstract

PURPOSE:To easily and inexpensively obtain a fuel having a high efficiency of combustion by compression-molding an organic waste, e.g. a kitchen refuse, into a board having many through-holes extending from one to the other side. CONSTITUTION:A cylinder 1 having on its side wall a fine mesh 13 through which only water permeates is provided with a press board 3 in a slidable manner. The board 3 is provided with projections 32 on its pressing side. A perforated board 2 having through-holes 22 penetrable by the projections 32 is disposed opposite to the board 3. An organic waste W, e.g. a kitchen refuse, is put in the cylinder 1 via a tilting passageway 12. The board 3 is forced down to compress the waste W. Simultaneously therewith, the waste W is pierced by the projections 32 to form many through-holes, and the resultant waste liquid is discharged through the mesh 13. Thus, the compression-molded objective fuel is obtained which is in a board form having many through-holes extending from one to the other side.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel which is made of organic waste such as raw garbage from a household, and a device for producing the fuel.

[0002]

2. Description of the Related Art Conventionally, as a fuel made from organic waste such as raw garbage, for example, raw garbage has been crushed and subjected to various complicated chemical, physical and biological treatments. It is known to dry and form into pellets.

The conventional technique for producing a fuel from such an organic waste as a raw material has a problem that the production cost increases because various treatment steps are required. On the other hand, it has a problem that it is not practical because it has a lower combustion efficiency than a fuel made of an organic raw material such as petroleum, coal and livestock excrement.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-mentioned problems, and provides a fuel having a high combustion efficiency at a low manufacturing cost and a device suitable for manufacturing the fuel. The challenge is to provide.

[0005]

In order to solve the above-mentioned problems, the organic waste fuel according to the present invention is, as shown in claim 1, compression-molded into a disk shape and a large number of air is flowed from the front surface to the back surface. It is characterized in that the holes are formed so as to penetrate therethrough.

In the organic waste fuel production apparatus according to the present invention, as described in claim 2, a cylindrical body having a fine mesh portion or a slit portion that allows only moisture to permeate, and slidable on this cylindrical body. A compression plate having a large number of projections fitted on the press surface and a perforated plate fixed to one end of the cylinder and having an insertion hole for penetrating the projections on the press surface. Adopt means.

Further, the apparatus for producing organic waste fuel according to the present invention, as set forth in claim 3, produces about 60 organic waste.
It is characterized in that the compression plate and / or the perforated plate are provided with heating means for heating to -80 ° C.

[0008]

According to the above-mentioned means, according to the first aspect, only the compression molding is performed, and the processing steps for the chemical, physical and biological conditions as in the above-mentioned conventional example are not required, so that the manufacturing cost is expanded. There is nothing to do. Moreover, since a large number of air holes are formed in the compression-molded disc-shaped fuel, the flow of air (oxygen) is improved during combustion, and combustion efficiency is improved.
Therefore, the problem of providing a fuel with low manufacturing cost and high combustion efficiency is solved.

According to the second aspect of the present invention, after the organic waste is put into the cylindrical body, the compression plate is slid with the pressing surface toward the waste side, so that the waste is generated between the compression plate and the porous plate. It is compression-molded into a disk shape and a large number of air holes are easily formed by the projections on the pressing surface. At the same time, the moisture contained in the waste is permeated and discharged from the mesh portion or slit portion of the cylinder and the perforated plate to be dried.

At this time, if the heating means is provided as described in claim 3, the waste can be heated from the front surface and / or the back surface at the same time during the compression operation, and the dryness can be further enhanced. . Furthermore, a sterilizing effect can be expected by this heating operation. That is, the bacteria contained in the organic matter can be killed by heating the compression plate and / or the perforated plate to heat the waste to 60 to 80 ° C. In this case, it goes without saying that the heating time and the heating temperature of the compression plate and / or the porous plate should be adjusted in consideration of the thickness of the plate-shaped waste after heating the pressing surface of the compression plate and the projections. . The lower limit is 60 degrees here because the sterilizing effect is significantly reduced below 60 degrees, and the upper limit is 80 degrees above which the sterilizing effect is not improved and the energy for heating is not improved. This is because the consumption is useless.

Embodiments of the organic waste fuel and the apparatus for producing the same according to the present invention will be described below with reference to the drawings.

1 to 3 show an embodiment of a fuel production apparatus according to the present invention. In this embodiment, a cylindrical body 1 for accommodating organic waste W such as domestic garbage is provided with a perforated plate 2 horizontally at the lower end and supported on a supporting leg 11. Although not shown in the figure, it is also possible to use a horizontal type in which the cylinder is laid sideways instead of the vertical type. The following description relates only to the vertical type. Above the side portion of the tubular body 1, a loading slope 12 for loading the organic waste W into the tubular body 1 is provided, and the side portion of the tubular body 1 below the lower end of the loading slope 12 is A mesh part 13 is provided. This mesh portion 13 (or slit portion, the same applies hereinafter) is erected in a tubular shape surrounded by a fine-corrosion resistant member that allows only water to pass therethrough, for example, a stainless steel net. Further, an outlet 14 for taking out the organic waste W that has been compression-molded into a disc-shaped fuel is provided on one side of the lowermost end of the side of the tubular body 1, and is normally closed by a door 15. A push-out port 16 is opened on the side facing the take-out port 14 and is closed by a door 17. An extruding rod 18 is slidably provided on the perforated plate 2 outside the door 17.

A compression platen 3 is forcibly suspended inside the cylindrical body 1 so that it can be moved up and down. This compression platen 3 has a cylindrical body 1.
It has a press surface 31 formed corresponding to the horizontal surface of (1) and a large number of protrusions 32 provided on the press surface 31, and is suspended by a rod 33. The protrusion 32 is set to have a length longer than the thickness of the organic waste W compression-molded into a disc shape. The rod 33 is usually connected to a press such as a cylinder (not shown), but it may be manually driven by a handle or the like. The protrusions 3 on the perforated plate 2
A large number of insertion holes 22 through which 2 is inserted are formed at locations corresponding to the large number of protrusions 32. Further, a waste liquid tray 19 is installed below the perforated plate 2, and a drainage pipe is connected to the waste liquid tray 19 to guide the waste liquid to a sewer pipe or the like.

The compression platen 3 is preferably provided with heating means 4. In this heating means 4, a heater is incorporated on the back side of the press surface 31 and in the projection 32, and the rod 33 is formed in a hollow shape, and a conductor of the heater is passed through the rod 33 to connect to the power source. Since the temperature of the pressing surface 31 and the protrusion 32 heated by the heating means 4 is sufficient to bring the organic waste W to about 60 to 80 ° C., a general household power source should be used. it can. Although not shown, it is more preferable to provide the heating means 4 on the porous plate 2 as well as the compression platen 3.

According to the embodiment of the apparatus for producing organic waste fuel according to the present invention, first, as shown in FIG. 1, a certain amount of organic waste is discharged from the charging slope 12 of the cylinder 1 into the cylinder 1. The material W is put in, and then the compression platen 3 is forcibly lowered as shown in FIG. 2 to compress the organic waste W. Then, the organic waste W is penetrated by the protrusion 32 and the insertion hole 22 to open a large number of air holes 5 and sandwiched between the compression platen 3 and the perforated plate 2 to be compressed. The waste liquid is discharged from the mesh portion 13 or the slit portion 13 on the side wall to remove the water content and solidify into a disc shape.

At this time, the press surface 31 is heated by the heating means 4.
If the perforated plate 2 and / or the protrusions 32 are heated, the organic waste W is further dried by heating and sterilized. Therefore, the organic waste W compression-molded into a disk shape does not decompose as a fuel in a short time. Further, in this compression heating, a large number of projections 32 are contained in the organic waste W compressed by the pressing surface 31 of the compression platen 3.
Since the protrusions 32 are penetrated, the inside of the organic waste W can be efficiently heated by heating the protrusion 32. Moreover, the air holes 5 formed by being penetrated by the projection 32 also have the effect of increasing the combustion efficiency of the organic waste W as a fuel.

After the organic waste W is formed into a disk shape as shown in FIG. 3, the compression disk 3 is raised in the tube body 1 to move it into the tube body 1.
The door 15 and the door 17 are opened, and the push rod 18 is horizontally projected onto the perforated plate 2 and dropped from the take-out port 14 and taken out.

It should be noted that the organic waste W in the aforementioned cylinder 1 is
It is also possible to pulverize the organic waste W at the time of charging, or to mix the organic waste W with a catalyst agent or the like for improving combustion efficiency.

FIG. 4 shows an embodiment of the organic waste fuel of the present invention.

The fuel of the organic waste W manufactured as described above is formed in a disk shape and can be stacked for convenient storage, and since it is dried, it has no offensive odor and is unlikely to rot. . In use, since combustion air flows through the air holes 5, the combustion efficiency is good. In particular, since the air holes 5 communicate from the front surface 6 to the back surface 7, the flow of combustion air is smooth. Further, when the fuel is too large, it is easy to have the air holes 5 to break the fuel.
