DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refuse treatment apparatus used for incinerating combustible municipal waste.

[0002]

[Prior art and its problems] Municipal waste such as paper and cloth
There are incombustible refuse such inflammable dust or empty cans and bottles, these garbage sieved and those ones of the flammable and nonflammable, followed flammable waste as shown in FIG. 4 Nigomi The garbage truck 6 puts the waste directly into the garbage pit 2 from the platform 5 serving as the garbage inlet. The volume of the refuse pit 2 is about 3000 cubic meters, and usually stores refuse for 5 to 6 days.

[0003] The waste put into the waste pit 2 is then transferred from the waste pit 2 by the crane 8 and thrown into the hopper 3. This operation is performed by the operator directly watching the dust pit 2 from the control room 7 or watching the image from the monitor camera 10 mounted above the dust pit 2. The refuse introduced into the hopper 3 is supplied to the incinerator 4 and incinerated while being transferred from the upstream 9a to the downstream 9b of the incineration line 9. Although incineration of garbage uses oil only at the time of ignition, it is carried out by self-combustion.
Above the refuse must be burned continuously. Therefore, in order to burn the refuse in the incinerator 4 without extinguishing the fire, it is necessary to supply the refuse from the hopper 3 to the incinerator 4 according to the combustion state in the incinerator 4.

[0004] However, some of the garbage collected by the garbage truck 6 contains a large amount of moisture, while others do not. This is true for garbage collected on a fine day. The garbage collected on the day is very wet. Therefore, in the garbage pit 2, garbage pits containing a large amount of water and garbage with a small amount of water are irregularly distributed, and the garbage stored in the garbage pit 2 is directly put into the hopper 3 and incinerated. If it burns out quickly, the fire in the incinerator 4 goes out, and if the garbage contains a lot of water, the water will extinguish the fire in the incinerator 4 or even until the fire does not go out, as shown in FIG. As in the case of the flame f, the combustion state was uneven and incomplete combustion occurred.

Therefore, in order to solve this problem, the refuse stored in the refuse pit 2 is agitated by a crane 8 to equalize the water content of the refuse in the refuse pit 2.
Actually, the water contained in the garbage
It was difficult to determine how the minutes were distributed .

[0006]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above problems, and has been made to make uniform the moisture of the refuse stored in the refuse pit, efficiently, and burn the refuse in an incinerator. It is an object of the present invention to provide a refuse treatment device in which a constant value is obtained.

[0007]

[Means for solving the problems] The purpose of the above
The combustible waste stored in the waste pit is placed above the waste pit.
Is supplied to the incinerator by the crane installed in the
Waste treatment equipment that incinerates the waste in a furnace
In the above , the air is blown toward the wall surface opposite to the wall portion on the upper portion of the wall portion on the side of the garbage input position of the garbage pit .
A wind separator is provided, and the air is blown out of the
Depending on the water content of the garbage thrown in from the entry position
It is unevenly distributed in the waste pit, and then
The garbage is further stirred to remove water in the garbage pit.
After being evenly distributed, supply the waste to the incinerator
This is achieved by a refuse treatment apparatus characterized by the above.

[0008]

[Function] Since an air outlet is provided above the wall on the garbage input position side, the refuse input from the garbage input position side is a relatively humid garbage containing a relatively large amount of moisture. Dry garbage that is unevenly distributed in the area and contains almost no moisture is unevenly distributed on the wall side opposite to the wall side of the garbage input position, so it is easy to distinguish between dry garbage and wet garbage. it can. Then, stir the waste with a crane,
After evenly distributing the water in the pit,
By supplying to the incinerator, the combustion rate is kept constant and the waste
Can be incinerated reliably.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a waste disposal apparatus according to an embodiment of the present invention will be described with reference to the drawings. The same components as those of the conventional example are denoted by the same reference numerals, and the description of the portions of the conventional example that are not sufficiently described will be supplemented.

FIG. 1 shows an entire refuse treatment apparatus 1 according to an embodiment of the present invention. Garbage input door 1 on platform 5
6 is provided, and the garbage truck 6 is a platform 5
When entering, the refuse input door 16 is opened.
A door switch 14 is attached to the refuse input door 16, and switches the switch between ON and OFF when the refuse input door 16 is opened and closed.

A wind separator 15 is attached to an opening 22 above the wall 23 on the platform 5 side of the waste pit 2, and the wind separator 15 is thrown into the waste pit 2 by the garbage truck 6. The garbage blows out the wind a in the direction of the arrow.
That is, dust is unevenly distributed on the side of the wall portion 24 facing the wall portion 23 to which the wind separator 15 is attached.

The crane 8 moves the dust holding portion 8a along the X axis in the drawing.
The dust can be freely moved in the Y-axis direction and the Z-axis direction, and the dust holding portion 8a conveys the dust in the dust pit 2 to the hopper 3.

FIG. 2 shows a platform 5 where the garbage truck 6 puts refuse into the refuse pit 2. On the side wall of the platform 5, a photoelectric tube 12 serving as a photoelectric switch and a light receiver 11 receiving the light are mounted to face each other. As shown, the garbage truck 6 on the platform 5
Comes in, the light emitted from the photoelectric tube 12 is blocked by the garbage truck 6, and it can be determined whether or not the garbage truck 6 is on the platform 5.

Next, control for operating the wind separator 15 will be described. FIG. 3 shows a state in which the refuse input door 16 is closed. When the refuse input door 16 is opened, the door switch 14 is closed and the constant voltage circuit 17 and the controller 13 are closed.
Is supplied with power. As a result, the constant voltage circuit 17 supplies a high-level signal to the AND circuit 18, and the controller 13 operates the photoelectric tube 12 and the light receiver 11. That is, when the garbage truck 6 is not on the platform 5, the light receiver 11
Receives light from the photoelectric tube 12 and the controller 13 is turned on to output a high-level signal, which is inverted by the inverting element 21 and outputs a low-level signal to the AND circuit 18. In this case, the gate of the AND circuit 18 is not opened and the relay 1
9 does not operate and the contact 19a remains open,
Is not powered. When the garbage truck 6 is on the platform 5, the light receiver 11 cuts off light from the photoelectric tube 12, the controller 13 is turned off, and a low level signal is output. To output a high-level signal. As a result, the gate of the AND circuit 18 is opened, the relay 19 is operated, and the contact 19
a is closed, power is supplied to the wind separator 15,
The wind a is blown in the direction of the arrow shown in FIG . Therefore, the gate of the AND circuit 18 is opened only when the refuse input door 16 is opened and the refuse collection vehicle 6 is at the platform 5.

When the garbage truck 6 leaves the platform 5, the light receiver 11 receives the light from the photoelectric tube 12 and
3 turns ON and outputs a high-level signal, but the inverting element 21 is inverted and outputs a low-level signal to the AND circuit 18. As a result, the gate of the AND circuit 18 is closed and the contact 19a of the relay 19 is opened, so that the supply of power to the wind separator 15 is stopped, and the blowing is stopped.

The refuse treatment apparatus 1 according to the embodiment of the present invention is configured as described above. Next, this operation will be described.

When the dust input door 16 is opened, power is supplied to the photoelectric switches 11 and 12. As shown in FIG.
When the garbage truck 6 arrives at the platform 5, light emitted from the photoelectric tube 12 is blocked by the garbage truck 6,
The light receiver 11 does not detect light. This is received by the controller 13, and the relay 19 is operated by the above-described circuit, so that the contact 1
9 a is closed, and power is supplied to the wind separator 15. Thereby, the wind separator 15 sends the wind a in the direction of the arrow.

As shown in FIG. 1, when the garbage truck 6 puts the refuse into the refuse pit 2, the introduced refuse is sent to the wind separator 15 above the wall on the platform 5 side, that is, immediately below the refuse inlet. , The garbage receives the wind a in the direction of the arrow by the wind separator 15. Garbage pit 2
There are wet and dry refuse such as paper and cloth put into the garbage, and naturally, wet refuse is heavier than dry refuse. Therefore, wet garbage with a large amount of water falls on the wall 23 on the platform 5 side, and if it is dry garbage, it is blown off to the wall 24 opposite thereto and falls. If the refuse is slightly wet, it falls in the middle of the refuse pit 2. That is, as for the refuse introduced into the refuse pit 2, a large amount of wet refuse is collected on the wall 23 side, and a large amount of dry refuse is collected on the wall 24 side. In the middle, a little damp garbage is collected. further
According to the present embodiment, the jet air of the wind separator 15 is applied to the opposing wall.
Because it is blown toward the wall of the part 24,
Garbage can be reliably stored in the garbage pit 2
You.

The waste put into the waste pit 2 is incinerated in the incinerator 4, but as described above, the fire in the incinerator 4 is kept from being extinguished, the waste is made uniform, and the waste is put into the hopper 3. Is done. Therefore, the refuse in the refuse pit 2 is stirred by the crane 8. The operator has one juicy where the garbage in garbage pit 2, and since know where to advance or there is moisture <br/> less, more wall 23 side of the dust moisture on the wall portion 24 side What is necessary is just to move and move the dry refuse from the wall part 24 to the wall part 23 side.

As described above, the worker can efficiently and surely equalize the dust without mistaking how the moisture contained in the dust in the dust pit 2 is distributed .

Next, the refuse whose moisture has been made uniform in the refuse pit 2 is put into the hopper 3 by the crane 8 and automatically supplied to the incineration line 9 of the incinerator 4. Since the moisture of the refuse is made uniform on the incineration line 9, the burning rate becomes almost constant as in the case of the flame F shown in FIG. 1, and the fire does not disappear on the way.

Although the embodiments of the present invention have been described above, the present invention is, of course, not limited thereto, and various modifications can be made based on the technical concept of the present invention.

For example, in the above-described embodiment, the wind separator 15 is moved only when the garbage truck 6 enters the platform 5.
Although the power is supplied to the wind separator 15, the power may be manually supplied.

[0024]

According to the present invention, the refuse introduced from the refuse input position is scattered on the wall on the refuse input side due to the blast air from the air outlet, and if it is dry refuse,
Since it is unevenly distributed on the wall opposite to the wall at the refuse input position, dry refuse and wet refuse can be easily distinguished. Thereby, the worker who stirs and equalizes the waste can efficiently and surely equalize the waste without mistaking how the moisture contained in the waste in the waste pit is distributed . Also, the refuse supplied to the incinerator is
Since the moisture in the refuse is made uniform, the burning rate is almost constant and the fire does not go out in the incinerator.
