Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underground incinerator ash extractor.

[0002]

2. Description of the Related Art An underground incinerator has a structure in which the main body of the furnace is installed underground and only the upper surface of the furnace is on the ground so that the entire surface can be released.

The incineration system is a top-burning gasification system, which is suitable for incinerating plastic that is difficult to incinerate because it does not clog because it does not have a grate, melts during incineration, and obstructs ventilation.

Since the underground incinerator is buried in the ground, there is no appropriate method for taking out ash, and the conventional underground incinerator is taken out by using a crane or a bucket from the upper opening. As a result, the operating rate is significantly reduced.

[0005]

SUMMARY OF THE INVENTION The present invention greatly improves such unsafe and inefficient ash removal.

The present invention solves the above-mentioned conventional problems, and provides an ash take-out device which can take out ash efficiently at a very low cost with a relatively simple facility, and has low power and is simple. It is an object of the present invention to provide an underground incinerator with a high operating rate, which is capable of discharging ash to the outside of the furnace extremely efficiently with a structure.

[0007]

In order to achieve the above object, the present invention forms a recess below the surface of the earth and slopes the bottom to form an ash discharge horizontal hole through an ash discharge vertical hole provided at the lower end of the slope. A cylinder is provided in a machine accommodating pit provided at one end of the lateral hole, an ash discharge vertical hole closing cylinder is provided at the tip of the cylinder, and an upper and lower surface opening box is provided at the tip of the cylinder. The other end of the horizontal hole is communicated with the ash storage pit, the closed cylinder and the upper and lower opening boxes are fitted in the horizontal hole so as to be reciprocally slidable, and the other end of the horizontal hole is opened on the inner wall of the ash storage pit. The underground incinerator ash extractor upper and lower surface opening box formed so that the standing hole is closed on the upper surface of the closed cylinder in a state where the box projects into the ash storage pit Is long in the direction of the lateral hole, and the width in the direction perpendicular to the direction of the lateral hole is almost It is composed of the same underground incinerator ashing device described in the above invention.

[0008]

In the present invention, when waste is put into the recess and burned, the combustion ash is accumulated at the bottom and passes through the ash discharge vertical hole at the lower end of the inclined surface and the closed cylinder of the vertical hole in the ash discharge horizontal hole. Is supported on the upper surface of the above, and is filled in the standing hole.

In this state, when the cylinder in the machine accommodating pit is contracted and the closing cylinder in the lateral hole is slid toward the cylinder to stop the upper and lower opening boxes at the tip just below the standing hole, the standing hole is opened. The combustion ash inside is lowered and stored in the box by its own weight.

When the cylinder is extended in this state, the closed cylinder and the upper and lower opening box slide in the lateral hole toward the ash storage pit side, and the box advances into the pit from the other end opening of the lateral hole. When stopped, the combustion ash in the box falls by its own weight to the lower part of the pit, and the upper surface of the closing cylinder closes the standing hole until it reaches the stopping position. It never falls inside.

Thereafter, the cylinder is contracted to position the box just below the standing hole, and the operation of dropping and storing the combustion ash in the standing hole into the box is repeated to store the ash accumulated in the bottom inclined portion of the recess. It can be discharged intermittently to the pit.

[0012]

EXAMPLE A primary combustion chamber 2'formed by a concave portion 2 is formed on the ground surface 1, a bottom portion 3 is inclined toward a central portion, and an ash discharging vertical hole 4 is formed in the central portion. The vertical hole 4 communicates with the central ceiling of a horizontal hole 5 for discharging ash formed in the lower portion thereof, and the combustion ash accumulated in the bottom 3 falls into the horizontal hole 5 through the vertical hole 4. .

The bottom part 3 may be partly an upright wall, and an upright hole 4 is provided at the lower end of the upright wall, and the bottom part 3 faces the upright hole 4.
The lower end of the inclined surface can be connected.

A pit 6 for accommodating a machine such as a cylinder 7 and its hydraulic equipment is formed at one end (left end in FIG. 1) of the lateral hole 5, and an ash accommodating pit 10 is formed at the other end (right end in FIG. 1). The bottom surface 10 ′ of the accommodation pit 10 is formed considerably lower than the level of the lateral hole 5, and an opening 12 is formed in the inner wall 11 of the accommodation pit 10.

A closed cylinder 8 for the upright hole 4 is provided at the tip of a rod 7'that moves in and out from the tip (right end) of the cylinder 7.
The upper and lower open boxes 9 that stop immediately below the upright holes 4 are provided at the tip of the cylinder 8 and the box 9 and the closed cylinder 8 are reciprocally slidably fitted into the lateral holes 5.

When the box 9 is moved to the left in FIG. 1 and stopped at a position directly below the upright hole 4, the combustion ash in the upright hole 4 and the bottom portion 3 is accommodated in the box 9 by its own weight.
After that, when the cylinder 7 is operated and the box 9 is slid from the solid line position in FIG. 1 to the phantom line position in FIG. 1, the upright hole 4 remains closed in the upper surface 8 ′ of the closed cylinder 8 and the box 9 remains in the ash storage pit 10. Projecting from the opening 12 of the lateral hole 5 into the inside of the
The ash in the box 9 falls into the pit 10 by its own weight. After that, the closed cylinder 8 and the box 9 are slid to the left in the position shown by the solid line in FIG. 1 so that the box 9 is located immediately below the upright hole 4 and the ash in the bottom 3 and upright hole 4 is lowered into the box 9 by its own weight. Is repeated.

The combustion ash stored in the ash storage pit 10 is discharged by an inclined conveyor, a bucket elevator or the like 13 to a carry-out conveyor or an ash receiving vat 14 on the ground surface 1. Reference numeral 15 in the drawing is a secondary combustion chamber connected to the primary combustion chamber 2 ', 16 is a chimney, 17 is an operation panel, 18 is a ladder, 19 is a waste inlet, and 20 is its opening / closing lid.

The vertical hole 4 has a width of 0.5 m and a depth of 0.5 m.
(The direction of the lateral hole 5), the depth is 0.8 m, the ash storage box 9 has a width of 0.5 m, a height of 0.5 m, and a length of 1 m in the direction of the lateral hole 5. The width in the direction perpendicular to the direction is substantially the same, and the box 9 is formed longer in the direction of the lateral hole 5 than the depth of the standing hole 4.

[0019]

Since the present invention is configured as described above, it is not necessary to take out the combustion ash accumulated at the bottom of the primary combustion chamber due to the recess to the surface of the ground from the waste input port of the recess using a crane or bucket, and the bottom of the bottom can be removed. Not only can it be easily discharged into the ash storage pit from the lateral hole provided in the box, but also the bottom standing hole is closed by the closing cylinder while the box reaches the pit, and the combustion ash to the lateral hole There is no drop scattering and there is an effect that it can be efficiently discharged into the pit with simple equipment.

The standing hole and the box have substantially the same lateral width, and the length of the box in the direction of the lateral hole is longer than that of the standing hole, so that the ash can be reliably stored in the box.
