DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for treating waste by means of at least two treatment lines installed side by side.

[0002]

2. Description of the Related Art Generally, in a treatment facility for treating wastes, various facilities such as coarse dust type and non-combustible type treatment facilities are installed. Normally, each system of these treatment facilities is provided independently to improve the efficiency of the treatment work, and the waste is directly input from a truck to the waste receiving hopper provided at the work start point of the treatment facility of each system. You can do it.

As a treatment facility for each system, for example, a coarse dust treatment system is provided with a crusher, a magnetic separator, and a trommel (rotary sieve) behind the receiving hopper, and an incombustible waste treatment system is provided behind the receiving hopper. A bag breaker, a bag separation conveyor, a magnetic separator, etc. are provided, and the optimum processing work is performed for each waste type by these facilities.

[0004]

However, when the waste is carried into the processing facility, the types of the waste loaded on the truck or the like are only incombustible waste, only coarse waste, or a mixed state thereof. Often, it is not known at the time of delivery, and it is not always easy to select it immediately. Also, when one system is in the process of processing and the receiving hopper is full, if the same type of waste material continues to arrive there, the truck cannot immediately put it into the receiving hopper, and the truck etc. I have to wait an hour. Further, although the waste is once sorted and put into the receiving hopper, even if the sorting is not appropriate, once it is put in, it is sent to an unsuitable processing facility as it is.

In the present invention, in consideration of the current state of the treatment in the conventional waste treatment facility described above, any waste is generated at the treatment work starting position on the upstream side of the treatment facility system for each type of waste. Provide a receiving hopper and an apron conveyor that can be operated in the normal and reverse directions. By this, the waste can be sorted or the time can be adjusted, and the waste can be transferred to each treatment system to provide a treatment system that can improve work efficiency. This is an issue.

[0006]

In order to solve the above problems, the present invention has at least two systems for receiving wastes such as incombustible dusts and bulky dusts and treating each waste type. Forward / reverse operation in which a processing facility is installed side by side, a receiving hopper that can directly input target waste is installed at the processing work start position of each system, and this receiving hopper and the hopper of the processing facility of each system above are connected to this receiving hopper. A free apron conveyor is provided, and the type of waste that is put into this apron conveyor is selected on this conveyor, and a waste treatment system that treats with an optimal treatment system is provided.

[0007]

According to the above system of the present invention, when the type of waste is unknown, the waste is put on the apron conveyor at the processing start position, the contents are sorted on this, and it is reliably transferred to the optimum processing system. To do. When the content of waste is known in advance, it is put directly into the receiving hopper of each processing system. However, the processing apparatus of the system to be loaded may be full, and in this case also, the apron conveyor at the processing work start position can be used. Therefore, the collection vehicle does not have to wait for a long time, and the processing work is performed extremely efficiently.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic block diagram of a waste treatment facility of the present invention.

1 is a waste receiving hopper, and 2 is an apron conveyor for the forward and reverse operation of the apron conveyor, and the apron conveyor is provided with two systems of waste treatment equipment. The system shown in the upper stage is a non-combustible waste treatment facility, 3 is a receiving hopper, 4 is an apron conveyor for non-combustible waste, 5 is a bag breaking machine, 6 is a bag separating conveyor, 7 is a magnetic separator,
Reference numeral 8 is a conveyor. The following processing equipment is not shown. Further, all of these individual processing facilities are known, and details thereof are omitted in the drawing.

The system in the lower stage is a treatment facility for coarse dust, 11 is a receiving hopper, 12 is an apron conveyor for coarse dust, 13 is a crusher, and 14 is a carry-out conveyor. Equipment is omitted. Further, individual processing equipment is also known, and details thereof are omitted in the drawing. The details of the treatment facility near the waste receiving hopper 1 and the apron conveyor 2 described above are shown in FIG. Collection vehicle X shown in FIG.
The hopper is provided in the pit 10 so that the hopper can approach any of the receiving hoppers 1, 3, and 11. The apron conveyor 2 is configured to be capable of rotating in the normal and reverse directions, and both ends thereof communicate with the receiving hoppers 3 and 11 of the above-mentioned two-system processing equipment.

In such a waste treatment facility, waste is treated as follows. First, when it is clear in advance whether the content of the waste is incombustible waste or bulky waste, the collection vehicle X directly approaches the receiving hopper 3 or 11 of the system for which the waste is suitable, garbage,
Alternatively, throw in large dust. However, there are cases where it is not clear in which system the content of waste should be treated. In this case, the waste is once put into the receiving hopper 1. In the vicinity of the hopper 1, an operator visually checks the thrown-in waste into non-combustible dust or coarse dust. If the result of the discrimination is non-combustible dust, the apron conveyor to the upper system of FIG. 2 is operated to transfer to the receiving hopper 3 of this system.

[0012] In this way, the waste can be treated in the treatment facility of the optimum treatment system. Therefore, the collection vehicle X does not have to wait for a long time, and the work is processed extremely efficiently.

Even if the contents of the waste are known in advance, the receiving hopper of the system to which the waste belongs may be full. Even in this case, the waste can be once put into the waste receiving hopper 1. When the work of the system to which the receiving hopper 1 belongs progresses while waiting, the receiving hopper 1
Wastes stored in the system will be transferred to either system and the work will be continued. Therefore, also in this case, the work is extremely smooth and efficient.

In the above embodiment, the non-combustible waste system and the bulky waste system are described as an example, but various systems other than the above may be provided as the system of the treatment equipment. It goes without saying that the method can be applied.

[0015]

[Effects] As described in detail above, the treatment method of the present invention has at least two waste treatment facilities installed side by side, and selectively discards the waste by means of an apron conveyor that can be operated in the forward and reverse directions provided at the upstream processing start position. Since the system is designed to transfer materials to the treatment equipment of each system, even if the content of the waste is unknown, it can be sorted on the apron conveyor and transferred to the optimal processing system, and the content of the waste can be understood. However, even if one of the processing systems is full, it is possible to wait on the apron conveyor when the processing system is full.
