Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ash removal device for a fixed-type refuse incinerator made of heat-resistant bricks. [0002] Conventionally, in fixed-type refuse 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. The ash is scraped from the ash.
In this case, not only does ash accumulate in the ash storage chamber and hinders ventilation in the furnace, reducing incineration efficiency.In addition, when removing ash during or immediately after incineration, touch the hot ash door, When scraping the ash, there was a risk of burns by directly touching the hot ash. [0003] The present invention provides an incinerator ash removal device capable of safely removing accumulated ash from the inside of a fixed incinerator. According to the present invention, an ash dropout port is opened at the bottom of an ash storage chamber formed at the bottom of an incinerator, thereby forming an ash storage chamber and an ash discharge hole formed thereunder. The ash fall opening is equipped with an opening / closing plate that opens downward around the support shaft, an opening is opened in the rear side wall of the ash storage room, and the bottom of the ash storage room between the rear side wall and the air opening is inclined. To form a high air outlet side, connect the air blower to the air outlet, and install the air blow guide at a low inclination toward the inside of the ash storage chamber,
In addition, an ash outlet was opened on the side wall of the ash storage room opposite to the air outlet. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described with reference to the accompanying drawings. FIG. 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. 4 is formed. Opening door 5 that can be opened and closed
Install. The waste inlet 3 and the ash removal port 4 are partitioned by the rostr 6 to form an ash storage chamber 11 below the roast 6, and the ash falls through the rost 6 and accumulates in the ash storage chamber 11. An ash fall port 7 is provided at substantially 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 is attached to be tiltable downward. On the upper surface of the incinerator 1, a chimney 10 is provided. On 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 opening, and the opening / closing plate lifting arm 13 is pulled up by a wire 14 to close the ash fall opening 7. [0007] A 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 dropped 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 accumulate 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 to the ash extraction hole 12 and the temperature of the ash is lowered at 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. According to the present invention, 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 blow guide inclined at a low angle toward the ash drop port. So, when the wind blows down along the slope and opens the opening and closing plate, the ash that has accumulated on the slope is reliably sent to the ash fall port,
This has the effect of dropping everything into the ash extraction hole.

Claims (1)

(57) [Claims] [Claim 1] An ash storage chamber is formed at the bottom of the incinerator, and an ash dropping port is opened at the bottom thereof, and the ash dropping port is opened downward around a support shaft. An opening / closing plate is provided, a ventilation port is provided on a rear side wall of the ash storage chamber, a bottom of the ash storage chamber between the ash falling port and the ventilation port is inclined to form a high ventilation port side, and a ventilation blower is provided in the ventilation port. At the same time, the blast guide is installed at a low inclination toward the inside of the ash storage chamber, and the opening and closing plate is opened, and the blast in the ash storage chamber is swept to the ash fall opening by the blower, so that the ash in the ash storage chamber falls outside the machine.
