[0002]

2. Description of the Related Art Solid wastes including construction wastes are separated for the purpose of reusing materials from the viewpoint of environmental protection. These separation treatments are carried out in a waste treatment plant having a solid waste separation system. The solid waste sorting system mainly includes a solid waste receiving section and a sorting section.

As the solid waste receiving section, a solid waste storage section for storing a solid waste group carried in from a construction site and a belt for mounting the solid waste and conveying it to the separation processing section. It is already known to have a conveyor. The belt conveyor is located at the bottom of the pit for loading the solid waste group. There, solid waste carried in from a construction site or the like is collected in a solid waste storage unit and put into a pit by a bulldozer or the like. The solid waste put in the pit is conveyed to the separation processing section by the belt conveyor at the bottom.

[0004]

In the solid waste receiving device of the solid waste sorting system, when the solid waste group collected in the solid waste storage section is placed on the belt conveyor, the solid waste is collected by the bulldozer. The group is pushed into the pit. However, in this case, excess solid waste easily overflows to the outside of the pit. For this reason, the solid waste group must be conveyed to the separation processing unit by the belt conveyor while adjusting the amount of waste input into the pit, and a large amount of solid waste cannot be processed.

An object of the present invention is to improve the transport efficiency of solid waste and to make it possible to increase the amount of acceptance.

[0006]

A pit portion 7 for processing the conveyed separated waste, a sieving portion 8 connected to a downstream end portion of the second conveyor portion 4, and a fourth conveyor connected to a downstream end portion of the sieving portion 8. It is composed of a unit 9 and a wind power sorter 10 connected to the downstream end of the fourth conveyor unit 9.

The storage unit 2 is composed of a substantially flat ground, and can store a solid waste group unloaded from a transportation vehicle such as a dump truck in a mountain shape. In addition, in the storage unit 2,
A solid waste group is pushed out in the arrow direction (the input direction) using a bulldozer or the like. The first conveyor unit 3 is arranged adjacent to the storage unit 2, and its transport direction (rightward in the drawing) is orthogonal to the loading direction of the storage unit 2. The first conveyor section 3 is composed of three belt conveyors 11, 12 and 13 each having a rubber annular belt. The belt conveyors 11, 12 and 13 are arranged parallel to each other and horizontally, and as shown in FIG. 3, a groove 14 formed on the ground.
Are located at the bottom of each.

On each of the belt conveyors 11, 12 and 13 on the side away from the storage section 2, the solid waste group introduced from the storage section 2 is fed to the belt conveyors 11, 12 and 13.
A guide plate 15 for guiding to 13 is attached.
The guide plate 15 extends upward along the side wall surface of the groove 14,
Further, it extends above the storage portion 2. The belt conveyors 11, 12 and 13 have a greater amount of expansion as they go forward in the loading direction of the storage unit 2. That is,
The upstream end of the belt conveyor 12 is the belt conveyor 1
It is arranged between the upstream end of No. 1 and the second conveyor unit 4. Further, the upstream end of the belt conveyor 13 is arranged between the upstream end of the belt conveyor 12 and the second conveyor unit 4. Further, as is clear from FIG. 1, each guide plate 15 is provided on the belt conveyors 11, 12, 13 at the portion exposed in the loading direction with respect to the reservoir 2.

With this configuration, the solid waste group fed from the storage section 2 is transferred to the three belt conveyors 11, 12, and 13.

Next, a solid waste processing operation in the construction waste processing plant 1 will be described. First, a solid waste group is placed on the storage unit 2 by a dump truck or the like. The placed solid waste group is put into the first conveyor unit 3 by a bulldozer or the like. At this time, since the guide plate 15 is attached to the upstream end of each belt conveyor 11, 12, 13 at the side away from the reservoir 2, it is excessively pushed into the groove 14. The overflow of solid waste groups is prevented. Moreover, even when the solid waste is piled up to the upper part of the guide plate 15,
Excess waste is sequentially guided by the guide plate 15 onto the belt conveyors 16, 17, and 18. Therefore, it is possible to increase the input amount when pushing the waste by the bulldozer. As a result, each belt conveyor 16, 17, 1
8 can improve the transportation efficiency of the solid waste group,
The amount of acceptance can be increased.

Each belt conveyor 1 of the first conveyor section 3

There, the conveyance speed of the belt conveyors 16, 17 and 18 is set to, for example, 8.0 m / min, and even if the solid waste group is thickly piled up in the first conveyor section 3, the belt conveyor is On 16, 17, and 18, it is developed to a thickness suitable for manual selection. Thereby, the worker on the scaffold 19 can easily perform the sorting work.

The solid wastes taken out by the sorting operation are dropped for each type on the belt conveyors 24 to 29 arranged below and stored in the pits 31 to 36 of the pit section 7, respectively. Here, since the second conveyor unit 4 intersects with the third conveyor unit 6, the sorting work can be easily performed. Next, at the downstream end of the second conveyor section 4, the magnetic separator 5 arranged above removes the metal pieces from the solid waste. Here, the metal piece is attached to the lower surface of the thin film belt 22 by the magnet 23 and falls above the conveyor 29. The metal pieces that have fallen onto the belt conveyor 29 are in the pit 3.
It is housed in 6.

Further, the solid waste passes through the sieving section 8. There, the solid waste is passed through a vibrating sieving machine 37, and a sieve below 10 mm falls on the belt of a belt conveyor 38. The waste on the sieving machine 37 (on the sieving machine) is put into the wind force sorter 10 via the fourth conveyor section 9.
