2. Description of the Related Art Conventionally, as a crushing and sorting apparatus for various kinds of waste, for example, there is one disclosed in Japanese Patent Publication No. 57-48262 of the same applicant.

Hereinafter, this conventional crushing / sorting apparatus will be briefly described with reference to the drawings. FIG. 2 is a partial cross-sectional view showing a conventional crushing and sorting apparatus. In FIG. 2, 1 is a crusher. The crusher 1 includes a vertical rotary shaft 3 housed in a casing 2, a plurality of chains 4 radially mounted on the vertical rotary shaft 3, and a blower blade 5 mounted below the vertical rotary shaft 3. It is configured.

Reference numeral 6 is a sorter connected to the crushed material discharge port 7 of the crusher 5. The sorting machine 6 is a cylindrical basket-shaped rotary sorting cylinder 9 placed horizontally on a roller 8, a driving means (not shown) for rotating the sorting cylinder 9, and fixed to the entrance of the sorting cylinder 9. It consists of 10 baffles.

According to this crushing / sorting apparatus, the waste introduced into the casing 2 of the crusher 1 by the conveyor 11 is crushed by the chain 4 rotating at a high speed and sent to the sorter 6. Of the crushed waste, the waste A such as metal or stone collides with the baffle plate 10 of the sorting machine and drops first, and the waste B such as wood chips and household dust is sorted by the sorting cylinder 9
The waste C, such as vinyl or paper, that has fallen from the mesh of the sorting cylinder 9 by the wind from the blower blades 5 of the shredder 1.
Falls from the rear.

[0006]

According to the above-mentioned crushing / sorting apparatus, it is possible to effectively crush and sort waste, but it is also necessary to sort highly accurately crushed waste. There may be. For example, if a large amount of wood pieces, glass, sand, fine glass pieces, etc. are mixed in the selected metal pieces, or plastic, foam polystyrene is mixed in a large amount in the selected household dust. However, in both cases, the reuse of waste is hindered.

Therefore, the object of the present invention is to crush the waste that has been crushed by a crusher and subjected to primary selection, such as heavy waste such as metal pieces, stones, medium quantity waste such as wood pieces and glass pieces, and vinyl and paper. An object of the present invention is to provide a sorting device capable of easily and surely sorting light waste such as.

[0008]

SUMMARY OF THE INVENTION According to the present invention, an input port for waste that has been crushed by a crushing and sorting machine and has been primarily sorted is formed in the upper portion, and heavy waste such as metal pieces and stones is discharged in the center side portion. An outlet is formed, and a medium-weight waste discharge port such as wood chips and glass fragments is formed in the central side portion facing the heavy waste discharge port, and the heavy waste discharge port is in the tank. A vibrating screen horizontally provided between the outlet and the lightweight waste discharge port, and a conveyor for discharging residues such as sand and fine glass fragments, which are provided at the bottom of the tank, dropped from the vibrating screen. A blower for feeding air into the tank below the vibrating screen, and a dust collector for sucking lightweight waste such as vinyl or paper from the tank above the vibrating screen. I have.

[0009]

According to the present invention, the waste that has been crushed and primary-sorted by utilizing the vibrating screen and the wind force,
Further, it is possible to easily and surely sort into heavy waste such as metal pieces and stones, medium amount waste such as wood pieces and glass pieces, and light weight waste such as vinyl and paper.

[0010]

Next, an embodiment of the sorting apparatus of the present invention will be described.
A description will be given with reference to the drawings.

FIG. 1 is a schematic front view showing an embodiment of the sorting apparatus of the present invention.

In FIG. 1, reference numeral 12 is a tank. 12A
Is a charging port provided in the upper part of the tank 12, from which the waste that has been crushed by the crushing and sorting machine (not shown) and that has been primarily sorted is fed into the tank 12. 12B is a heavy waste discharge port provided on the center side of the tank 12 such as metal pieces and stones. 12C is a medium-volume waste discharge port such as a piece of wood or a piece of glass, which is provided on the central side opposite to the heavy-weight waste discharge port.

Reference numeral 13 denotes a heavy waste discharge port 12A in the tank 12.
It is a vibrating screen horizontally installed between the light waste discharge outlet 12B and the light waste discharge outlet 12B. 14 is provided at the bottom of the tank 12,
This is a conveyor for discharging residues such as sand and fine glass pieces that have fallen from the vibrating screen 13. Reference numeral 15 is a blower for sending air into the tank 12 below the vibrating screen 13. 16 vibrating screen 13
Is a dust collector for sucking lightweight waste such as vinyl and paper from the inside of the tank 12 above.

According to the sorting apparatus of the present invention having such a configuration, the crushed waste is further sorted as follows. As the waste, for example, waste such as metal pieces and stones crushed and sorted by the crushing and sorting machine shown in FIG. 2 will be described as an example.

Waste material is introduced by the conveyor 17 into the inlet 12A.
When the waste is put into the tank 12, the waste falls on the vibrating screen 13. When the waste falls on the vibrating screen 13, the residue such as sand and fine glass fragments mixed in the waste is removed by the vibrating screen.
After passing through the 13th sieve, it falls on the conveyor 17 and is discharged to the outside of the tank 12. Lightweight waste such as vinyl and paper on the vibrating screen 13 rises to the upper part of the tank 12 as the wind from the blower 15 passes through the vibrating screen 13 and is removed by the dust collector 16.

Of the wastes on the vibrating screen 13, heavy wastes such as metal pieces and stones move to the heavy waste discharge port 12A side,
On the other hand, medium-sized waste such as wood chips and glass fragments moves to the lightweight waste discharge port 12B side. In this way, only the metal pieces and stones are sorted from the waste that has been primarily sorted. It should be noted that it is possible to easily select only the metal pieces from the metal pieces or stones by a known magnetic separator or the like.

[0017]

As described above, according to the present invention, the waste that has been crushed and primary-selected by utilizing the vibrating screen and the wind force, and further the heavy waste such as metal pieces, stones, etc. In addition, it is possible to easily and surely sort into medium-sized waste such as wood pieces and glass pieces and light-weight waste such as vinyl and paper.
