Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solid waste receiving apparatus, and more particularly to a solid waste receiving apparatus in a solid waste treatment system having a separation processing unit for separating solid waste groups.

[0002]

2. Description of the Related Art Solid waste including construction waste and the like is 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. As a solid waste sorting system, there is already known one including a sorting processing unit for sorting the solid waste group and a solid waste receiving device for guiding the solid waste group to the sorting processing unit. . The solid waste receiving device is composed of a storage unit for storing the solid waste group and a transfer unit for receiving the solid waste group input from the storage unit and transferring it to the separation processing unit. .

The transfer section is composed of a belt conveyor or the like adjacent to the storage section. The solid waste group is loaded into the belt conveyor from the side and is conveyed to the separation processing unit by the belt conveyor.

[0004]

In the above-mentioned conventional solid waste receiving apparatus, only one belt conveyor is adjacent to the storage section, and a large amount of solid waste cannot be conveyed. If the amount of conveyance cannot be increased, the amount of separation processing cannot be increased. An object of the present invention is to improve the transportation efficiency of a solid waste group to a separation processing unit.

[0005]

A solid waste receiving apparatus according to the present invention is an apparatus in a solid waste processing system having a separation processing unit for separating and processing a solid waste group. This apparatus includes a storage unit for storing a solid waste group, and a transfer unit that receives the solid waste group input from the storage unit and transfers it to the separation processing unit. The transport unit includes a plurality of conveyors that extend in a direction intersecting the loading direction in the loading direction front side of the storage unit, and that the upstream end in the transport direction extends further in the forward direction of the loading direction.

[0006]

In the solid waste receiving apparatus according to the present invention, a plurality of conveyors intersect the loading direction in front of the solid waste group loading direction of the storage section. In addition, in the plurality of conveyors, the upstream end in the transport direction extends further forward as it goes from the reservoir to the front in the loading direction.

For this reason, the solid waste group can be introduced into the plurality of conveyors from the side. Therefore, the transport efficiency of the solid waste group to the separation processing unit can be improved.

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.

Has become.

Next, a solid waste treatment operation in the construction waste treatment 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, the belt conveyors 11, 12 and 13 are located at the upstream end portions 11a and 12 as they go forward in the loading direction (arrow direction in the figure) of the storage unit 2.
Since a and 13a extend further ahead, a large amount of solid waste group can be received at one time by the three belt conveyors 11, 12, and 13. Therefore, it is possible to improve the efficiency of transporting the solid waste group to the second conveyor unit. Further, the guide plate 15 can prevent the overflow of the solid waste group introduced from the reservoir 2 to the belt conveyors 11, 12, and 13.

Each belt conveyor 1 of the first conveyor section 3
The solid waste groups placed on 1, 12, and 13 are, for example,
It is conveyed to the second conveyor section 4 at a conveying speed of 2.5 m / min. Since the belt conveyors 11, 12, and 13 are arranged horizontally, the driving force for pulling up the solid waste, which has been conventionally required, is unnecessary. Next, the solid waste group consists of the belt conveyors 11 of the first conveyor section 3,
Belt conveyors 1 to 12 and 13 to the second conveyor section 4
It falls on 6, 17, and 18. Belt conveyor 16,1
The conveying speed of 7, 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 unit 3, the belt conveyor 1
On 6, 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 piece that has fallen onto the belt conveyor 29 is in the pit 36.
Housed in.

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.
The glass introduced from the inlet 50 of FIG.
And collide with the upper step portion 52a. At this time, combustible materials such as plastics, papers, and wood chips mixed in the glass are decelerated and separated to some extent. further,
The glass is guided by the duct 51a and passes in front of the outlet of the blower 53. At this time, the combustible material in the glass, which is easily affected by the wind force, is blown away by the wind pressure and separated from the blower port 54a to the adjacent duct 51b. Further, the glass is again subjected to the same sorting by the step portion 52b and the blower 53b arranged below. Thus, the sorted solid wastes are collected from the combustibles outlet 55 and the incombustibles outlet 56, respectively.

[Other Embodiments] In the above embodiment, the first conveyor section 3 is provided with three belt conveyors 11, 12, 1.
However, the present invention can be implemented even when the number of belt conveyors is two or four or more.
