[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste storage pit in a waste incineration plant.

[0002]

2. Description of the Related Art Conventionally, for example, a waste storage pit of a waste incinerator as shown in FIG. 14 is known.

[0003] In the figure, reference numeral 101 denotes a platform on which refuse is to be thrown in by a garbage truck 102 that has entered,
103 is a waste pit for storing waste, 104 is a waste crane, and 105 is a waste hopper.

Here, the flat surface of the refuse storage pit is determined based on the site area, the construction of the plant, and the like.
The garbage pit 103 generally has a capacity of two to three days, but the area of the garbage incinerator is limited.
The depth was obtained by underground drilling to secure the waste storage volume.

[0005] In the garbage storage pit having such a structure, even if the garbage crane 104 breaks down, the garbage from the garbage collection vehicle 102 is received for about one day unless garbage is extremely stored in the garbage pit 103. It can be accepted without any problem, and the operation room of the garbage crane 104 can be lowered to the second floor level (in the case where the position where the refuse is charged is at the first floor level), and can be installed together with the central operation room. There is an advantage.

On the other hand, since the depth of the refuse pit 103 is deep, it is difficult to construct the pit 103 at a place where the groundwater level is high. Also,
It is necessary to take sufficient waterproof measures. In addition, there is a risk that refuse is input from the refuse collection vehicle 102. Garbage pit 10
3 is deep, so you may be afraid.
The construction of No. 03 is costly and takes a lot of time. There is also a disadvantage that the space above the first floor is wasted and cannot be used effectively.

Therefore, a waste storage pit disclosed in Japanese Utility Model Laid-Open No. 4-57032 has been proposed as shown in FIG. In the figure, 201 is a platform, 202 is a refuse collection unit, 203 is a refuse pit for storing refuse, and 204 is a refuse hopper.

The bottom surface 202A of the refuse collection unit 202 is lower than the level of the platform 201 on which the refuse collection vehicle 205 enters. The garbage pit 203 is adjacent to the garbage collection unit 202,
Is surrounded all around by a wall 206 higher than the level.

[0009] Waste hopper 2 adjacent to the waste pit 203
04 is arranged. Then, a garbage main crane 207 is disposed above the garbage pit 203, and the garbage main crane 207 includes
The second refuse is transferred to the refuse pit 203, and the refuse in the refuse pit 203 is thrown into the refuse hopper 204 into the refuse collection unit 202.

In the waste storage pit, the waste hopper 2
The depth of the underground pit of 04 is about 3-4m,
Since the garbage truck 205 normally works only in the daytime, when the garbage transferred to the garbage pit 203 on the garbage incinerator side is incinerated at night, a fully automatic crane system at night is used.

Since the underground portion of the garbage pit 203 is significantly shallower, the moving range of the garbage crane 207 in the height direction can be reduced. There is also an advantage that, when there is no partition wall, it does not hurt to see the garbage pile.

[0012]

[Problem to be Solved by the Invention] However, one waste crane 207 is moved from the waste collection unit 202 to the waste pit 2
03, and the waste transfer from the waste pit 203 to the waste hopper 204. There is a problem that the operation rate of the operation for the waste transfer operation is low.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to improve the operation rate of the operation of a waste crane for transferring waste from a waste pit to a waste hopper. The goal is to provide a waste storage pit that can be used.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 to 13 show a waste storage pit according to an embodiment of the present invention.

In the figure, 1 is a platform, 2 is a waste collection unit, 3 is a waste pit for storing waste, 4
The garbage hoppers are shown respectively. The refuse collection unit 2 is configured in a slender space, and the bottom surface 2A is lower than the level of the platform 1 from which the refuse collection vehicle 5 enters.

The waste pit 3 is adjacent to the waste collection unit 2,
It is surrounded by a first partition wall 3A, a second partition wall 3B, a back wall 3C, and a front wall 3D higher than the level of the platform 1. Between the end 3E of the first partition wall 3A and the back wall 3C,
An opening 3F is formed, and the garbage pit 3 and the garbage collection unit 2 communicate with each other via a lower portion of the opening 3F. In addition, the bottom surfaces of the refuse collection unit 2 and the refuse pit 3 are formed on the same plane, and are inclined with a downward slope toward the refuse wastewater pit 13 described later.

Between the end 3E of the first partition wall 3A and the left side wall 6, refuse input doors 7, 7, 7 are provided. The platform 1 is located on the left side of the first partition wall 3A, and the dust hoppers 4, 4 are arranged adjacent to the waste pit 3 in a state of being separated by the second partition wall 3B.

At the center of the back wall 3C, there is a first partition wall 3A.
The projection 8 is formed near the right side of the end 3E and is formed by the inclined surfaces 8A and 8B and forms an obtuse angle. The height position of the upper end of the projection 8 is substantially the same as the height position of the upper end of the first partition wall 3A.

Reference numeral 9 denotes a main crane for refuse, which is disposed above the refuse pit 3 and is capable of traveling in the depth direction, a traveling device 9B traveling on the rail 9A in the left-right direction, and a traveling device. The hopper 9C is suspended from the hopper 9C and runs horizontally and vertically.

A garbage sub-crane 10 for transferring garbage from the garbage collection unit 2 to the garbage pit 3 is installed above the garbage collection unit 2, and a rail support unit 12 suspended from a ceiling 11 and a left side support unit 12. A rail portion 10A suspended horizontally between the walls 6, and a traveling device 10B traveling on the rail portion 10A
And a hopper 10C suspended from the traveling device 10B. The rail support portion 12 is configured to be inclined, and its tip projects above the dust pit 3. And the tip of the rail 10A near the opening 3F
Extends upward near the opening 3F in the garbage pit 3.
In the garbage pit 3, the lane near the opening 3F
Below the tip of the garbage part 10A, inward of the garbage pit 3.
The above-mentioned inclined surface 8A is provided at a predetermined height from the bottom surface 3G.
Have been.

As shown in FIGS. 9 to 13, a waste pit 13 is provided outside the wall of the waste pit 3, and a screen 14 is provided between the waste pit 3 and the waste pit 13. . The screen 14 is composed of a number of pillars 14A having a triangular cross section and standing upright with a predetermined gap therebetween.
A gap 14B of about 30 mm is formed between A and 14A, and the rear portion of the gap 14B of the screen 14 is wide.

In this embodiment, the refuse collection vehicle 5 enters the platform 1 and refuse is introduced into the refuse collection unit 2 from the refuse input door 7. Then, the refuse sub-crane 10 transfers the refuse of the refuse collection unit 2 to a position below the rail support unit 12 of the refuse pit 3.

When the garbage pit 3 is highly loaded with garbage, a small amount of garbage falls from the garbage pit 3 to the garbage collection unit 2 through the opening 3F, but one input door on the right side is closed. Also, refuse can be input from the two refuse input doors 7 on the left side. In addition, when the garbage caught by the hopper 10C of the garbage sub-crane 10 is thrown into the garbage pit 3, the garbage is guided away by the inclined surface 8A of the projection 8 and thus is thrown away from the vicinity of the opening 3F. Therefore, dust does not accumulate near the opening 3F, and the ingress of the dust pit 3 into the dust collection unit 2 is reduced.

The dust spreads over the entire surface while being deposited in the dust pit 3 due to its fluidity. As for the deposited waste, the waste in the waste pit 3 is thrown into the waste hopper 4 by the waste main crane 9.

[0027] In addition, since the dust collection unit 2 Togomi pit 3 is in communication with, refuse sewage is collected in garbage sewage pit 13. That is, the bottom 2A of the waste collection unit 2 and the waste pit 3
Since the bottom surface 3G is inclined toward the waste sewage pit 13, the sewage is collected in the sewage pit 13 as shown by an arrow in FIG. Then, while the garbage in the garbage pit 3 flows out of the gap 14B of the screen 14 to the garbage pit 13 through the screen 14, the garbage is blocked by the screen 14, and the garbage and the garbage are separated. The refuse blocked by the screen 14 is removed by the main refuse crane 9, so that the refuse is not clogged and blocked.

According to the above configuration, the refuse sub-crane 10 can transfer the refuse of the refuse collection unit 2 to the refuse pit 3 , so that the refuse pit is independent of the operation of the refuse sub-crane 10. The waste main crane 9 can be used for the operation of throwing the waste in the waste hopper 3 into the waste hopper 4.
The operating rate of the operation (from the waste hopper 4) can be improved.

Further, the slender waste collection unit 2 includes a waste pit 3
Is disposed at a right angle, the position of the first partition wall 3A of the garbage pit 3 can be shifted to the left so that the area of the garbage pit 3 can be widened, so that the garbage main crane 9 can be obtained. In addition, the function of stirring the waste so as to be uniform can be satisfied, the stirring of the waste in the waste pit 3 can be facilitated, and the stirring efficiency of the waste can be improved. Further, conventionally, as shown in FIG.
Even if 03 is divided, the garbage pit 2 is located on the left side of the partition wall of the garbage pit 203.
The plane of 03 is restricted, and it may be necessary to dig a pit underground to secure the volume,
In this embodiment, as described above, the area of the dust pit 3 can be made large, so that such a concern can be solved.

Further, conventionally, since there is only one garbage crane, the garbage input to the garbage collection unit can be used as it is.
In some cases, flammable and non-flammable materials are solidified and sent to the refuse incinerator, which may cause unstable combustion. Reference numeral 9 denotes a structure that does not pick up the refuse of the refuse collection unit 2 and, therefore, refuse is always sent in the order of the refuse collection unit 2 → the refuse pit 3 → the refuse hopper 4. And transferred to the refuse hopper 4, so that combustion in the refuse incinerator can be stabilized.

Since the refuse sub-crane 10 is a crane that only travels along the rail portion 10A, sensors for detecting the height of a refuse layer below the rail portion 10A are provided at intervals of 1 to 2 m. The position where garbage should be transported can be determined with a burst, so that when the input door 7 is opened, it does not pass through that position, and when it is at that position, it is rolled up and the input door 7 is closed. By setting up a program that waits until fully automated, it can be easily automated.
