Abstract

PROBLEM TO BE SOLVED: To remove deposited ash in safety from the inside of a fixed incinerator by inclining the bottom face downward from the air supply opening of a blower to the ash drop opening and providing the air supply opening with an air supply guide which inclines toward the ash drop opening. SOLUTION: A blower 15 for supplying outdoor air into a incinerator 1 is provided at the lower part on the back of the incinerator, and the air supply opening 17 of the blower 15 is inclined below a grate 6 in order to accelerate incineration of refuse. A downward inclining face 16 is provided on the bottom face of the incinerator 1 from the back face thereof to the ash drop opening 7, in order to collect ash dropping from the roster 6 at the ash drop opening 7. Furthermore, an air supply guide 18 inclining downward is formed at the upper edge of the air supply opening 17, in order to collect ash on the inclining face 16 at the ash drop opening 7 by supplying air from the blower 15. When an open/close plate 8 is opened in that state, ash collected at the ash drop opening 7 is blown out along the inclining face 16, dropped into an ash removal hole 12 and deposited on the bottom thereof by supplying air from the blower 15.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ash extraction device for a fixed-type incinerator made of a heat-resistant brick.

[0002]

2. Description of the Related Art Conventionally, in fixed incinerators,
An ash outlet is formed below the refuse inlet provided on the front side wall, the furnace is divided into upper and lower parts by a roaster, and the ash generated by incineration falls down through the roaster and accumulates in the ash storage chamber. To scrape ash from
In this case, not only does the ash accumulate in the ash storage chamber and hinders the ventilation in the furnace, lowering the incineration efficiency.In addition, when removing the ash during or immediately after incineration, touch the hot ash outlet door, When scraping the ash, there was a danger of burns by directly touching the hot ash.

[0003]

SUMMARY OF THE INVENTION The present invention provides an incinerator ash removal device capable of safely removing accumulated ash from the inside of a fixed incinerator.

[0004]

According to the present invention, an ash dropping port is opened at the bottom of an ash storage chamber formed at the bottom of an incinerator, thereby communicating the ash storage chamber with an ash discharge hole formed thereunder. At the ash falling port, an opening / closing plate that opens downward around the support shaft is attached, an air vent is opened on the rear side wall of the ash storage chamber, and the bottom of the ash storage chamber between the rear side wall and the air vent is inclined to blow air. The mouth side is formed high, and a blower is connected to the blower outlet, and the blower guide is installed at a low inclination toward the inside of the ash storage chamber,
Further, an ash outlet was opened on the side wall of the ash storage room opposite to the air outlet.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described with reference to the accompanying drawings. 1 is a front sectional view showing the configuration of the incinerator of the present invention, FIG. 2 is a plan sectional view thereof, and FIG. 3 is a side sectional view thereof.
The incinerator 1 is formed by stacking heat-resistant bricks on a base frame 2 made of a combination of steel materials to form a box shape, and a garbage inlet 3 for charging incinerated material and a ash intake below the front side wall. 4 is formed. The garbage inlet 3 can be opened and closed freely.
Install. The refuse inlet 3 and the ash removal port 4 are partitioned by the rooster 6, and an ash storage chamber 11 is formed below the storm 6, and the ash falls through the storm 6 and accumulates in the ash storage chamber 11. An ash fall port 7 is provided substantially at the center of the bottom surface of the ash storage chamber 11, and an opening / closing plate 8 for closing the ash fall port 7 is provided.
One side of the opening / closing plate 8 is supported on the base frame 2 by a pair of fulcrum arms 9 and attached to be tiltable downward. A chimney 10 is provided on the upper surface of the incinerator 1.

[0006] In the bottom surface of the ash storage chamber 11, an ash extraction hole 12 is formed by digging deeply so as to face the ash falling port 7. One side of the opening / closing plate 8 is pivotally supported by a fulcrum arm 9,
The open side is inserted into the ash extraction hole 12. The ash take-out hole 12 is so deep that the opening / closing plate 8 can be sufficiently inclined so that no ash remains on the opening / closing plate 8. Opening / closing plate 8
An opening / closing plate lifting arm 13 is attached to the open side of the, and the opening / closing plate lifting arm 13 is pulled up by a wire 14 to close the ash fall opening 7.

An air blower 15 for blowing outside air into the furnace is provided below the back of the incinerator 1.
Tilt 7 below Rostor 6 to expedite the incineration of blast waste. On the bottom surface from the back of the incinerator 1 to the ash drop 7, an inclined surface 16 is provided downward from the back, and the ash that has fallen from the roaster 6 is collected at the ash drop 7. Further, a blowing guide 18 is formed to be inclined downward at the upper edge of the blowing port 17, and the ash on the inclined surface 16 is collected in the ash falling port 7 by the wind of the blowing blower 15.

When the opening / closing plate 8 is opened in this state, the ash collected at the ash falling port 7 by the wind of the blower blower 15
And fall into the ash extraction hole 12 to be deposited on the bottom thereof. Further, the ash that has fallen and deposited between the ash collecting port 4 and the ash falling port 7 on the front can be easily scraped out from the ash collecting port 4 with a scraping rod or the like. In this operation, even if the ash remains at a high temperature, the blower 15
The ash is discharged into the ash extraction hole 12 and the temperature of the ash is lowered in the ash extraction hole 12. Then, the ash can be easily taken out by a machine such as a shovel-type excavator without the operator directly handling the high-temperature ash. In addition, the number of persons involved in the ash extraction work can be reduced, and labor can be saved.

[0009]

According to the present invention, since the bottom surface from the blow port of the blower blower to the ash drop port is inclined downward, and the blow port is provided with a blower guide which is tilted low toward the ash drop port, the wind blower is provided. Blows down along the slope and opens the opening and closing plate, and the ash deposited on the slope is reliably sent to the ash fall port,
This has the effect of dropping everything into the ash extraction hole.
