Abstract

PROBLEM TO BE SOLVED: To obtain an incinerator with a fire grate which enables easier separation into resins, metal and the like after incineration by forming an opening part from an upper part to a lower part of the fire grate while the fire grate has a sufficient strength. SOLUTION: After the incineration of matters 2 to be incinerated, metal fittings separated from resins are caught in a gap (about 5mm long) between bars 12 composing a fire grate 11 to be accumulated as slag 57 of metal on a carrier surface 17 of the fire grate 11. A user inserts an ash takeoff device into an upper part of the inside of an opening port 6 to manipulate a handle of the ash takeoff device so that the slag 57 of the metal on the carrier surface 17 is taken out by an L-shaped plate to be housed into a first housing bag. Then, the user inserts the ash takeoff device into a lower part of the inside of the opening part 6 to manipulate the handle thereof so that the slag 56 of resins accumulated on a bottom part 4 of a combustion furnace 3 is taken out by the L-shaped plate to be housed into a second housing bag. Thus, the slag 56 of the resins and the slag 57 of the metal can be simply discriminated and collected.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an incinerator.

[0002]

2. Description of the Related Art Conventionally, an incinerator for burning an incineration object by a combustion burner is disclosed in, for example, Japanese Patent Application No. 7-311 by the present applicant.
No. 720 filed. In this incinerator, a combustion burner is provided on a side of a combustion furnace, and a lid is provided on an upper inlet. In order to prevent the incinerated material from falling down, for example, a relatively large pitch (50 to 60 m
A grate consisting of a plurality of rods arranged in m) is arranged inside the combustion furnace. An opening is formed in a side of the combustion furnace located below the grate, and a door is provided for opening and closing the opening.

[0003]

In the above-described incinerator, when incinerated objects (for example, clay fired by clay shooting) in which plastic (resin) and metal fittings (metal) are integrated, the melted plastic and metal fittings are used. Fell from the grate and settled at the bottom of the furnace. Then, the user opened the door and used the ash extraction tool to remove the residue. However, the residue has a first drawback in that the molten plastic and the metal fittings are integrated and cannot be collected separately.

Further, the grate is composed of a plurality of aligned rods, and a short rod is used in a portion along the inner surface of the cylindrical combustion furnace, which has a second disadvantage that the strength is insufficient. Accordingly, the present invention provides an incinerator having a grate having sufficient strength that can be easily separated into plastic (resin) and metal fittings (metal) after incineration in consideration of such conventional disadvantages. .

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a combustion furnace which has a bottom and sides and is formed in a cylindrical shape and in which incineration materials are stored, and which is disposed in the combustion furnace. A grate and a door that opens and closes an opening formed on the side are provided, and the opening is formed above and below the grate.

The present invention desirably includes a plurality of aligned rods,
The grate is constituted by the opening plate adjacent to the bar located at the end.

Have been. The legs 54, 55 are fixed to the mounting plates 50, 51. The incinerator 1 is constituted by the above components.

Next, the operation of the present incinerator 1 will be described again with reference to FIGS. First, the user turns the handle 29 clockwise to open the lid 24, inserts the incineration object 2 through the inlet 23, and turns the handle 29 counterclockwise to close the lid 24. Thereafter, the smoke elimination burner 46 is operated, and the high-temperature exhaust gas flows into the smoke elimination furnace 33.

In this manner, when the temperature inside the smoke-removing furnace 33 reaches a predetermined temperature, the combustion burner 20 is operated, and
Start the incineration operation of. Then, the gas generated from the combustion furnace 3 enters the smoke removing furnace 33 via the duct 43, is made smokeless by the smoke removing burner 46, and is discharged to the atmosphere via the chimney 49.

When the combustion burner 20 is operated for a predetermined time (for example, 1 to 3 hours) and the incineration operation is completed, the combustion burner 20 is stopped. After that, for a while, smoke removal burner 4
Continue the operation of No. 6 and perform smokeless operation. Thereafter, when a predetermined time has elapsed, the smoke elimination burner 46 is stopped, and the entire operation is stopped.

Thereafter, when the time elapses and the temperature of the combustion furnace 3 or the like is sufficiently lowered, the user opens the door 7. At this time, the incinerator 1 includes an incinerated material 2 in which plastic and metal fittings are integrated.
The molten plastic (for example, clay powder fired by clay shooting) is incinerated, and the melted plastic falls from the gap between the rods 12 constituting the grate 11 and accumulates as resin residue 56 on the bottom 4 of the combustion furnace 3. The above-mentioned melted plastic is grate 1
1 also falls through the holes of the opening plates 13 and 14 which constitute 1.

The metal fittings, which are incinerated from the incinerated material 2 and separated from the plastic, are caught in the gaps (length: about 5 mm) between the rods 12 constituting the grate 11 and are placed on the mounting surface 17 of the grate 11. Is accumulated as metal residue 57.

Then, the user can use the ash extractor 5 shown in FIG.
8 is inserted into the upper part of the opening 6 and the handle 5 of the ash extracting tool 58 is inserted.
9, the metal residue 57 on the mounting surface 17 is taken out by the L-shaped plate 60, and the first storage bag (not shown) is used.
Housed inside.

Next, the user inserts the ash extractor 58 into the lower part of the opening 6 and operates the handle 59 to cause the resin residue accumulated on the bottom 4 of the combustion furnace 3 by the L-shaped plate 60. 56
Is taken out and stored in a second storage bag (not shown). Thus, the resin residue 56 and the metal residue 57 can be easily separated and collected. This concludes the description of the operation of the present incinerator 1.

[0027]

According to the present invention, as described above, the openings formed on the sides of the combustion furnace are provided above and below the mounting surface of the grate. As a result, the residue of the incinerated material (eg, metal residue) remaining on the mounting surface of the grate and the residue of the incinerated material (eg, resin residue) remaining below the mounting surface are easily separated. Can be collected separately.

The present invention preferably comprises a plurality of aligned rods;
A grate is made up of an opening plate adjacent to the bar located at the end. Thus, the mechanical strength of the grate is increased by disposing the aperture plate at the end. Further, by disposing the aperture plate at the end, the aperture plate follows the inner wall of the combustion furnace. As a result, it is possible to prevent large ones (for example, metal fittings) from falling down among the incinerated objects located on the grate.
