Abstract

PURPOSE:To prevent explosion and to diminish load on breaking power by breaking waste with a cutting breaker to remove gas, classifying large blocks and small blocks with a classifier and crushing the large blocks with a crusher. CONSTITUTION:Waste is compressed and cut by a disk in the cutting breaker 1 to remove combustible gas. The waste is classified by a classifier 6 into large blocks and small blocks, metal is taken out by a 1st magnetic classifier 10 in the course of transfer of the small blocks by a conveyor 11 and transferred to a metal storing pit 13. The small blocks which are not taken out by the 1st magnetic classifier 10 are transferred into a nonmetal storing pit 14 through the conveyor 11. The large blocks from the classifier 6 are transformed by the crusher 15 into the small blocks. The small blocks from the crusher 15 are classified by a 2nd magnetic classifier and sent to a metal storing pit 13, nonmetal is sent to a non-metal storing pit 14, the small blocks are sent from the pit 13 to a compactor 17 and compacted then, transmitted by a truck from the pit 14 to a reclaimed site.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention is used in the field of crushing empty cans and the like in which flammable gas remains.

(b) Conventional technology In general, waste contains empty cans such as gas cylinders that contain residual flammable gas, and when the empty cans are crushed by impact, the flammable gas that flows out from the empty cans is released into the crusher. Fill up.

When impact crushing is performed in a crusher filled with flammable gas, there is a risk that the sparks generated by the collision between the hammer and the metal will ignite the flammable gas and cause an explosion inside the crusher.

Therefore, conventionally, as disclosed in Japanese Patent Application Laid-Open No. 56-89849, a crusher is filled with non-oxygen gas to carry out impact crushing treatment.

(C) Problems to be Solved by the Invention However, in the above structure, the crusher must always be filled with non-oxygen gas, which is very uneconomical.

Also, depending on the shape of the crusher, there is a risk that some flammable gas may remain, leading to an explosion.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a crushing device that removes gas remaining in empty cans to prevent explosions before impact crushing.

(d) Means for Solving the Problems The present invention provides a cutting and crushing machine that cuts and crushes empty cans, etc. and removes residual gas inside the empty cans, and separates the crushed empty cans, etc. into large lumps and small lumps. The present invention relates to an apparatus for crushing empty cans, etc., which is comprised of a sorter for sorting, and an impact crusher for crushing the large chunks sorted by the sorter into small chunks by impact crushing.

(e) Effect Empty gas cylinders, etc. are put into the cutting and crushing machine.

The cutting and crushing machine cuts and crushes empty cans, removes flammable gas from inside the cans, and crushes them.

At this time, since the crushing work is performed by cutting, sparks are not generated as is the case with impact crushing.

A sorter separates large chunks of crushed empty cans, etc.

The selected large lumps are put into a crusher, and the large lumps are crushed into small pieces.

(f) Embodiments Hereinafter, an embodiment of the invention will be described with reference to the drawings. (1) is a cutting and crushing machine for cutting and crushing waste.

The cutting and crushing machine (1) has a casing (
2) Two rotating shafts (3) (3) at the top and one at the bottom.
A book rotation axis (3) is provided, and the upper rotation axis (3) (3) is rotated in opposite directions by independent motors (4') (4'), and the lower rotation axis (3) is independent. The motor (4) is rotated in the same direction as either one of the upper rotating shafts (3) (3).

The rotating shaft (3)... has a plurality of disk-shaped disks (
5)... are fixed at equal intervals.

The disks (5) are arranged to be inclined with respect to the rotating shaft (3), and when the rotating shaft (3)... is rotated, the space between the opposing disks (5) (5) gradually becomes narrower so that the outer edges of the disks (5) (5) pass each other.

(6) is a sorting machine that separates large lumps from small lumps, and the sorting machine (6) rotates a drum (8) having a plurality of holes (7) with a diameter of about 15 cm. The waste transferred from the cutting and crushing machine (1) by the conveyor (9) is sorted by the first magnetic separator (10), and the magnetic separator (10) is sorted by the sorter (6). The metal is taken out from the small lumps transferred by the conveyor (11) and transferred to the metal storage bit (13) via the conveyor (12).

Small cullets and earth and sand not taken out by the first magnetic separator (10) are transferred to a non-metal storage bit (14) via a conveyor (11).

(15) is an impact crusher which performs impact crushing by rotating a hammer, and is designed to crush large chunks from the sorter (6) into small chunks.

(16) is a second magnetic separator that separates the waste from the impact crusher (15) into the metal storage bit (13) side and the non-metal storage bit (
14) It is designed to sort into two sides.

(17) is a compactor for compression molding the waste from the metal storage bit (13).

(18) (18) is a transport vehicle.

(19) is a conveyor.

Incidentally, in the embodiment, a cutting and crushing machine is provided with a disc mounted on a rotating shaft.The present invention has the above-mentioned configuration, and its operation will be explained next.First, waste is introduced into a cutting and crushing machine (1).

In the cutting and crushing machine (1), opposing disks (5) (5)
The waste is compressed and cut between the outer edges of the disks (5) (5), especially in the case of empty cans such as gas cylinders, to remove flammable gas.

By the way, some of the combustible gas removed is in the casing (2)
However, since the crushing is compression cutting and no sparks are generated, there is no risk of explosion.

The waste crushed by the cutting and crushing machine (1) is transferred to the sorting machine (6)
It is sorted into large lumps and small lumps.

While the small lumps are being transferred by the conveyor (11), the metal is taken out by the first magnetic separator (10) and transferred to the conveyor (12).
is transferred to the metal storage bit (13) via the metal storage bit (13).

Among the small pieces, those not taken out by the first magnetic separator (10) are transferred to the nonmetal storage bit (14) via the conveyor (11).

The large chunks from the sorter (6) are fed into the impact crusher (15), where they are crushed by impact into small chunks.

The small pieces from the impact crusher (15) are transferred by a conveyor (19) and sorted by a second magnetic separator (16).

Metals sorted by the second magnetic separator (16) are transferred to a metal storage bit (13), and nonmetals are transferred to a nonmetal storage bit (14).

From the metal storage bit (13), the metal is sent to a compactor (17), compressed and molded, and transported to a recycling factory or a landfill by a transport vehicle (18).

The non-metal storage bits (14) are transported to a landfill by a transport vehicle (18).

(g) Effects of the invention As described above, the present invention performs cutting and crushing using a cutting and crushing machine,
A sorting machine separates large lumps and small lumps, and a crusher crushes the large lumps by impact.

This allows the cutting and crushing machine to remove flammable gas, preventing the impact crushing machine from being filled with flammable gas and preventing explosions.Also, unlike the cutting and crushing machine, non-oxygen gas is constantly supplied. Since there is no need to store it, it can be used at low cost.

Further, since the materials crushed by the cutting crusher are sorted and only large pieces are supplied to the impact crusher, the burden of crushing power on the impact crusher can be reduced.
