Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refuse processing apparatus, and more particularly to a processing apparatus for municipal waste.

[0002]

2. Description of the Related Art FIG. 3 shows the whole of a conventional municipal solid waste processing apparatus. In the garbage pit 1, municipal solids collected by a dump truck are thrown in. With the dust M accumulated up to the height as shown in the figure, the dust dumping work by the dump trucks sequentially arriving at the fixed time of the day, for example, at 4 pm, is stopped.

Next, the worker 21 of the waste plant switches to automatic operation of this plant, but the waste in the waste pit 1 is uneven, not being thrown in flat as a whole. The worker 21 directly looks at the inside of the pit 1 and operates the crane 6 to make it flat, or while observing the image from the monitor camera on the monitor TV, operates the crane to make the dust in the pit almost flat. To do.

After this, the crane 6 is switched to automation, but the hopper 3 always stores dust, which is sequentially stored on the incinerator Q side by a natural drop from the hopper 3 to cause a stoker for incineration. The level meter L is provided in the hopper, and when the signal from this L determines that the level of dust in the hopper 3 is below this level, the crane 6 automatically operates. Then, it is moved down into the waste pit 1, and the amount of waste corresponding to this capacity is nipped, conveyed to the hopper 3, and thrown therein. Next, it arrives again inside the dust pit 1 to prepare for the next transportation. In response to this work, the dust pit 1 is divided into a plurality of checkerboard-like patterns in a plan view, which are stored in the computer. Each address is given to each of the addresses, but according to this address order, for example, if starting from the mth row and the nth column as shown in FIG. Next, the crane 6 is clamped by the crane 6 and put into the hopper 3.

As described above, the crane 6 operates each time together with the detection signal of the level meter L of the hopper 3, and sequentially moves according to the address in the dust pit 1 and according to the program of the computer to sequentially move the dust pit 1. Before the automatic switching, the dust M, which has been made substantially flat before being automatically switched, is grasped by the crane 6 and conveyed to a position above the hopper 3, where it is thrown in.

Before the automatic switching, the worker 21 in the plant
The dust M in the dust pit 1 has to be made almost flat, but this work is very cumbersome and inaccurate. That is, if the operation is switched to the above-described automatic operation in the uneven state, the amount of dust grasped by the crane 6 is too small in some cases, and the crane 6 frequently follows a predetermined route by the detection signal of the level meter. You have to make a round trip. In some cases, there is a risk of empty gripping. The crane 6 moves downward when it reaches a predetermined address specified by the computer, grabs dust at a predetermined address, and conveys it to the hopper 3. However, depending on the unevenness of the accumulation, Fear.

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and the flattening of the dust in the dust pit after the end of the dump truck by the dump truck and the predetermined address from the dust pit after the automatic switching are performed. An object of the present invention is to provide a waste processing device that can surely carry out the work of grasping and throwing the waste into the hopper.

[0008]

[Means for Solving the Problems] The above object is to provide a means for emitting / detecting a light wave or a sound wave above the dust pit so as to be movable in a horizontal plane, and seeing the dust pit in a plan view to form a plurality of dust traps. Divided into regions, the emission / detection means is moved along a predetermined path in a horizontal plane, and the height of dust accumulated in the plurality of regions is sequentially detected by reflected light or reflected sound waves, and based on the detection result. The present invention is achieved by a waste processing device characterized in that the waste in the waste pit is processed for a predetermined purpose.

[0009]

[Operation] Emitting light waves or sound waves above the garbage pit
A detection means, for example, a laser emission / detection means, is provided, which can move in a horizontal plane in the X direction and the Y direction along a predetermined program. This garbage pit is divided into a plurality of areas when viewed two-dimensionally. This is because a program in the computer allows the garbage transport means, such as a crane, to move sequentially along this program. However, prior to this, for example, the laser emission / detection means moves in a horizontal plane, so the height of dust accumulation at each address is detected by the reflected light, and this is stored in the computer to determine which area and how much dust accumulation. It is memorized whether or not the piles are piled up at a height, and after switching to the automatic switching, the cranes grab the piles in descending order of the pile height based on this memory so that the cranes throw the piles into the hopper according to the level detection signal from the hopper. As a result, the crane does not miss the grip and the amount of the grip is not particularly small, and almost the same amount of dust can be always grabbed and thrown into the hopper. Therefore, after the crane has been reciprocated a certain number of times, it can be maintained in a substantially horizontal state,
After this, start from 1 row and 1 column as before,
Alternatively, the garbage may be sequentially grabbed by a crane and loaded into the hopper from one corner.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an apparatus for treating municipal solid waste according to an embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, parts corresponding to those of FIG. 3 showing a conventional device are designated by the same reference numerals, and detailed description thereof will be omitted.

FIG. 1 shows the entire processing apparatus for municipal solid waste according to an embodiment of the present invention. The pit 1 has a known size, and the municipal solid waste M successively carried by the dump truck 2 is shown. Are put in this pit 1. A hopper 3 for sequentially supplying the municipal solid waste M to an incinerator (including a stoker) Q is disposed on the side of the pit 1, and a level detector 4 is attached to the hopper 3. This may have a known structure, for example, the hopper 3
You may make it detect the level by the change of the internal pressure applied to the inner wall of. The output signal of the level detector 4 is supplied to the computer 22 in the control tower 20.

A worker 21 is installed in the control tower 20.
However, it is possible to observe the state of dust accumulation in the pit 1 through the glass window G. In addition, a video camera 11 is arranged on the side of the pit 1, and this is a pillar 12
The video signal from the video camera 11 is also supplied to the computer 22 in the control tower 20. A crane device 6 is mounted above the pit 1, and the crane catcher 7 is configured to be movable in the left-right direction and the vertical direction in the figure as indicated by an arrow a. further,
According to the present invention, the laser emission detector 8 is attached to the driving device 9, which is configured to be movable along the guide rails 10a and 10b in the horizontal direction in the figure and in the direction vertical to the paper surface. The detection signal from the laser emission detection body 8 is supplied to the computer 22 in the control tower 20. According to this embodiment, the laser L from the laser emission detector 8
The a is emitted to the dust M in the dust pit 1, the reflected light from this is used to detect the deposition height of the dust M in this portion, and this detection signal is supplied to the computer 22.

The waste disposal apparatus according to the embodiment of the present invention is constructed as described above, and its operation will be described below.

The dump truck 2 puts in the garbage pit 1 the refuse M sequentially called from various parts of the city. As described above, such a dumping operation of dust ends at a fixed time of the day, for example, at 4:00 pm, and thereafter, conventionally, the worker 21 enters the dust M in the dust pit 1 through the glass window G. By operating the crane 6 while observing the accumulation state of No. 1 and driving the crane catcher 7 to move it to the left or right or in the direction perpendicular to the paper surface, the accumulated dust M is conveyed from a high place to a low one. After making it almost flat,
It was switched to an automatic refuse incineration operation after this.

However, according to the present invention, the laser beam La is emitted from the laser emission detector 8 toward the dust M in the dust pit 1. This is moved at a predetermined pitch in the left-right direction and in the direction perpendicular to the paper surface in FIG.

In FIG. 2, the dust pit 1 is divided into a grid pattern (planned by a computer program) when viewed two-dimensionally. In the same manner, the sections are divided in the same size and shape. According to the present embodiment, the laser emission detectors 8 are intermittently operated according to the grid pitch of the grid from the section A in the first row and the first column. The reflected height of the laser beam La of the sections B, C ... Detects the deposition height of the dust M of each section A, B, C ... in the dust pit 1, and supplies this detection signal to the computer 22. However, it is supposed to be stored in this storage circuit.

According to the present embodiment, after the dump truck 2 has stopped the operation of throwing in the dust, the worker 21 does not need any work for flattening the dust M in the dust pit 1 as in the conventional case. Since a program for moving the laser emission detector 8 at a predetermined pitch and route is incorporated in the computer 22, it is only necessary to push a button.

Although the crane catcher 7 automatically moves according to the program, according to this embodiment,
Rather than sequentially moving in a matrix order along rows and columns as in the prior art, the crane catcher 7 sequentially moves the sections stored in the computer 22 in order from the highest section of the dust accumulation height. If the garbage, for example, m rows and n columns of garbage is accumulated at the highest height, the crane catcher 7 is automatically moved above this section, and the computer 22 also sets the garbage accumulation height in each section. The height of the waste is memorized and arranged in order of height to supply a command from the computer to the crane device 6, and to which section is to be moved next for each reciprocating motion of the crane. The catch division order is automatically programmed according to the size. The waste from the hopper 3 slides down the chute part and is supplied to the stoker 5,
The incinerated waste that is incinerated here is discharged to a predetermined location by a conveyor (not shown).

If the difference in the section of the second highest dust accumulation height due to the amount of dust caught by the crane catcher 7 at one time is greater than the amount of catcher once, the m-th row and n-th column, that is, the most The crane catcher 7 having a high pile height catches it and supplies it to the hopper 3.

When the level detector 4 detects that the level of the level of the level of the level of the level of the level of the level of the level of the level of the level of the level of the level of the level of the level of the level of the level detector 4 is constantly reduced, the level detector 4 detects that the level of the level of the dust has decreased to a level below this level. From now on, a drive signal is given to the crane device 6 so that the crane catcher 7 catches the dust M in the highest section among the sections A, B, C, ...
I am trying to throw it in. When the level detector 4 detects that dust has not been thrown in to this level in one throwing operation, the crane catcher 7 is further continuously operated to catch the dust and make the throwing operation.

Further, according to the present embodiment, the video camera 11
Due to this, the worker 21
It is possible to observe whether or not the above-mentioned operation is reliably performed even in the above-described automatic operation, and in some cases, the crane catcher 7 is operated manually. Then, the worker may catch the refuse M in the section that he / she thinks appropriate by the crane catcher 7 and throw it into the hopper 3, or may convey it to another section in the refuse pit 1 and deposit it there.

The embodiment of the present invention has been described above.
Of course, the present invention is not limited to this, and various modifications can be made based on the technical idea of the present invention.

For example, in the above embodiments, the height of each section of the accumulated dust M in the dust pit 1 is detected by the laser beam, but instead of this, the height may be detected by ultrasonic waves. Good.

Further, although the present invention is applied to the automatic operation of incineration of refuse in the above embodiments, the present invention is not limited to this, and for example, the height of dust accumulated in each section is detected by the reflected light from the laser emitting detector 8. Immediately after this, memorize this, and automatically move the crane catcher 7 to each section in order to flatten the uneven trash in the dust pit 1 according to the assembled program so that it will be flattened. May be.
