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

0002

2. Description of the Related Art Generally, in a waste treatment facility, treatment facilities are installed for various systems, such as those for bulky waste and those for incombustibles. Normally, each system of these processing facilities is set up independently in order to make processing work more efficient, and waste is directly input from a truck or the like into a waste receiving hopper installed at the starting point of each system's processing facility. It is now possible to do so.

As processing equipment for each system, for example, the bulky waste processing system is equipped with a crusher, magnetic separator, and trommel (rotary sieve) behind the receiving hopper, and the non-combustible waste processing system is installed behind the receiving hopper. A bag tearing machine, a bag separation conveyor, a magnetic separator, etc. are installed, and these facilities perform optimal treatment for each type of waste.

[Problem to be Solved by the Invention] However, when waste is transported to a treatment facility, the types of waste loaded on trucks, etc. may be only non-combustible garbage, only bulky garbage, or a mixture of these. In many cases, it is not known at the time of delivery, and it is not always easy to sort them out immediately. In addition, if one system is in process of processing and the receiving hopper is full, if the same type of waste continues to arrive there, it will not be possible to immediately dump the waste from the trucks, etc. into the receiving hopper, and the trucks, etc. will take a long time. have to wait an hour. Furthermore, even if the waste has been sorted and thrown into the receiving hopper, but the sorting is not appropriate, once the waste has been thrown in, it will be directly sent to an inappropriate treatment facility.

[0005] The present invention takes into consideration the current state of processing methods in conventional waste processing facilities as described above, and provides a system for processing equipment for each type of waste, with a receiving hopper and a receiver for receiving any type of waste in the upper stage. To provide a processing method that improves work efficiency by providing an apron conveyor that can be operated in reverse, connecting each processing system, and sorting the waste or adjusting the time to transfer the waste to each processing system. The task is to

[0006]

[Means for Solving the Problems] In order to solve the above problems, the present invention provides at least two systems of processing equipment for processing each type of waste, such as non-combustible garbage and bulky garbage, and provides processing equipment for each system. The target waste can be directly thrown into the receiving hopper at the starting position, and a receiving apron conveyor that can be operated in forward and reverse directions is installed at the upper stage of the receiving hopper and the hopper, and the waste to be thrown into this apron conveyor is connected to both hoppers. This is a waste treatment method in which the types of waste are sorted on this conveyor and processed by the optimal treatment system.

[0007]

According to the above method of the present invention, when the type of waste is unknown, it can be thrown onto the upper receiving apron conveyor, the contents of which can be sorted, and the waste can be reliably transferred to the most suitable treatment system. When the content of waste is known in advance, it can be directly thrown into the receiving hopper of each treatment system. However, the processing equipment of the system to which the product is to be input may be full, and in this case as well, the upper receiving apron conveyor can be used. Therefore, the collection vehicles are not kept waiting for a long time, and the processing work is carried out extremely efficiently.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples 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 that implements the treatment method of the present invention.

Reference numeral 1 denotes a waste receiving hopper, and 2 a receiving apron conveyor, which is configured to be able to be operated in forward and reverse directions, and two systems of waste processing equipment are provided for this apron conveyor. The system shown in the upper row is the processing equipment for non-combustible garbage; 3 is a receiving hopper, 4 is an apron conveyor for receiving non-combustible garbage, 5 is a bag tearing machine, 6 is a bag separation conveyor, 7 is a magnetic separator, and 8 is a transport conveyor. It is. The following processing equipment is not shown. Furthermore, all of these individual processing facilities are well known, and detailed illustrations are omitted.

[0010] The lower system is a bulky garbage processing equipment, 11 is a receiving hopper, 12 is an apron conveyor for bulky garbage, 13 is a crusher, and 14 is an output conveyor. Similar to the upper system, the following processing is performed. Equipment is omitted. Further, individual processing equipment is also well known, and details thereof are omitted from illustration. Details of the processing equipment near the waste receiving hopper 1 and receiving apron conveyor 2 described above are shown in FIG. 2 and below. A hopper is provided in the pit 10 so that the collection vehicle X shown in FIG. 1 can approach any of the receiving hoppers 1, 3, and 11. The receiving apron conveyor 2 is configured to be capable of forward and reverse rotation, and both ends thereof are connected to the receiving hoppers 3 and 11 of the two processing equipment systems.

[0011] In such waste treatment facilities, waste is treated as follows. First, when it is clearly known in advance whether the content of the waste is non-combustible garbage or bulky garbage, the collection vehicle rubbish,
Or throw in bulky garbage. However, there are cases where it is not clear which system should be used to treat the contents of the waste. In this case, the waste is once placed into the receiving hopper 1. The thrown waste is visually judged by a worker near this hopper 1 to determine whether it is non-combustible waste or bulky waste, and if the result of the judgment is non-combustible waste, it is transferred to the receiving apron to the upper system in Figure 1. The conveyor 2 is operated to transfer to the receiving hopper 3 of this system.

[0012] In this way, the waste can be treated with the treatment equipment of the optimal treatment system. Therefore, the collection vehicle X is not kept waiting for a long time, and the work is processed extremely efficiently.

Furthermore, 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 temporarily thrown into the waste receiving hopper 1. If the work of the system to which it belongs progresses while it is waiting in receiving hopper 1, then receiving hopper 1
The waste stored in the system will be transferred to one of the systems and work will continue. Therefore, in this case as well, the work becomes extremely smooth and efficient.

Although the above embodiment has been described as an example in which a non-combustible waste system and a bulky waste system are installed together, various systems other than the above-mentioned processing equipment systems can be provided, and in that case, the present invention also applies. It goes without saying that the method can be applied.

[0015]

[Effects] As explained in detail above, the treatment method of the present invention has at least two systems of waste treatment equipment, and a receiving apron conveyor installed in the upper stage that can be operated in forward and reverse directions.
Since waste is selectively transferred to the processing equipment of each system, even if the contents of the waste are unknown, the waste can be sorted on the receiving apron conveyor and transferred to the most suitable processing system. Even if the contents of the processing system are known, it is possible to have the processing system stand by on the receiving apron when one processing system is full, which has the advantage of greatly improving work efficiency.
