2. Description of the Related Art Conventionally, electric and electronic devices such as cellular phones, personal computers (PCs), televisions, radios, video tape recorders (VTRs), microwave ovens, refrigerators, etc. are collected as non-combustible waste, and are manually and hydraulically operated. It has been mechanically pulverized by large machinery such as cutting machines, crusher devices, and heavy machinery.

[0003] Of these, in the case of portable telephones and personal computers, precious metals are mainly collected and crushed for recycling, but most of them require reducing the volume as little as landfill. It is an object.

[0004]

As described above, conventional portable telephones, personal computers, televisions, radios, VTs
Electric and electronic devices such as a microwave oven, a microwave oven and a refrigerator are mechanically pulverized by a crusher or the like.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail. The crushing device for electric and electronic equipment includes a water storage section for storing water therein, an explosive or pyrotechnic disposed in the water stored in the water storage section, and an electric charge disposed in the water in the water storage section. A collection unit for collecting crushed materials formed by crushing electronic devices by explosion of explosives or pyrotechnics;

The electric / electronic equipment to be crushed is a concept including all of the electric equipment and the electronic equipment and the electric parts and the electronic parts constituting them. Specific examples of electric / electronic devices include mobile phones, personal computers, televisions, radios, VTRs, microwave ovens, refrigerators, vacuum cleaners, and the like. The electric and electronic devices are composite products mainly including plastic and including metal and the like.

The water storage portion is capable of storing an appropriate amount of water therein, and includes a water storage container, that is, a water tank, a water storage hole formed by excavating land, a reservoir, and the like. The size of the water storage unit is appropriately determined in consideration of the target processing capacity of electric and electronic devices, the explosive power of explosives or pyrotechnics, the degree of influence on the surroundings, and the like.

An explosive or pyrotechnic is detonated by an electric detonator or the like, and crushes electric and electronic devices by its explosive power. In other words, it means an explosive that detonates in water by a primer and generates an underwater shock wave. Examples of explosives include general explosives such as hydrous explosives, dynamites, TNT (trinitrotoluene), pen slits, and penlights, as well as plastic explosives such as C-4, RDX (trimethylene trinitroamine), HMX and the like. High explosives,
Further, an inexpensive AN-FO explosive (a nitrate explosive) using a hydro-explosive or dynamite as a parent die is used. As pyrotechnics, all explosives filled in detonators, detonating wires, metal cases, etc. are used.

The amount of explosives or pyrotechnics used is determined by the strength and number of electric and electronic devices, the strength of the water storage unit, and the like. The larger the amount of explosive or pyrotechnic used at one time, the stronger the shock wave is generated. Therefore, the range that can be crushed is increased, and it is possible to crush electric and electronic devices with high strength. However, the use of explosives or pyrotechnics in general is limited to hundreds of grams to several kilograms in a steel tank, since shock waves that exceed the strength of the water storage section will destroy the water storage section. The pond weighs several kilograms to tens of kilograms.

The energy for crushing the electric and electronic devices is preferably such that a shock wave of at least 1 MPa acts on the electric and electronic devices, and more preferably a shock wave of 10 MPa or more acts on the electric and electronic devices. With a shock wave of less than 1 MPa, it becomes impossible to sufficiently separate and collect plastic and metal of electric and electronic devices. In other words, the distance between explosives or pyrotechnics and electrical and electronic equipment
The distance at which a shock wave of at least 1 MPa acts on electric / electronic devices is preferable, and the distance at which a shock wave of 10 MPa or more acts on electric and electronic devices is more preferable.

When a plurality of explosives or pyrotechnics are arranged,
By using electric detonators having an appropriate time difference (second difference) (MS electric detonator, DS electric detonator), a plurality of explosives or pyrotechnics can be sequentially detonated. It is also possible to employ a method in which a plurality of blasting buses and blasting devices set so as to be energized at certain time intervals are used, and a method is used in which an electric detonator is energized and sequentially detonated, or a method in which an IC detonator is sequentially detonated. it can. In this case, the electric and electronic devices slightly move due to the water flow, but move in a unit of several seconds, ie, 25 ms.
This is not a major problem with commercial electric detonators that detonate from (milliseconds) to 250 ms. It is desirable to use the MS electric detonator for the interval of the blasting time from the viewpoint of preventing the movement of the electric and electronic devices.

In actual crushing by blasting, the amount of explosives that can be used may be smaller than the preferable amount of explosives due to problems such as the size of the water tank used, the strength of the water tank, noise given to the surroundings, and ground vibration. In such a case, the amount of explosive per explosion can be reduced by dividing the explosive into a plurality of parts and sequentially firing them. For example, explosives or pyrotechnics are divided into a plurality of parts and detonated at time intervals of 100 ms or more, so that noise and ground vibration can be effectively reduced.

The space is for attenuating the explosive power generated by the explosion of an explosive or a pyrotechnic. This space can attenuate shock waves in proportion to the thickness thereof, and can greatly attenuate underwater shock waves even with a thickness of only about 1 mm. That is, the effect of crushing can be attenuated by about 60% in a space having a thickness of 1 mm, and can be attenuated to about 40% at 5 mm and about 20% at 10 mm. From these guidelines, adjust the desired degree of crushing. The space portion is formed of a soft material such as a wrap film or a polyethylene bag, a thin metal plate or wood, which does not let air escape, does not allow water to pass through, and is capable of retaining air for a period until the explosion.

The location of the explosive or pyrotechnic is usually desirable near the center of the water storage unit (half the depth to the bottom and the center in the horizontal direction). The depth from the surface of the water to the explosive or pyrotechnic may be at least the depth of the water such that the crushed material crushed by the explosion of the explosive or the pyrotechnic does not fly. Specifically, 200g
It is preferable that the explosive amount is up to about 1 m and the explosive amount up to about 500 g is up to 2 m. For explosives of about 1 to 5 kg, 4 m or more is preferable for explosives of about 5 to 10 kg.

On the other hand, the depth from the explosive or pyrotechnic to the bottom should be such that the bottom of the water storage section or the recovery section is not damaged, specifically, 1 m if the explosive amount is about 200 g.
As described above, 2 m or more is desirable if the explosive amount is about 500 g. 5 m or more for explosives of about 1 to 5 kg
If the amount of explosive is about 10 to 10 kg, the length is preferably 6 m or more.
The positional relationship between the explosive or pyrotechnic and the electric or electronic equipment may be any of the upper, lower, left, and right directions, but it is desirable to determine the explosive or pyrotechnic in consideration of the above viewpoint.

The recovery section is for collecting and recovering crushed materials formed by crushing electric and electronic devices by explosion of explosives or pyrotechnics. Specifically, in addition to a wire mesh, a water storage container, that is, a bottom portion of a water tank, and the like are given.
It is preferable that the wire mesh is suspended on a wire or the like, and is pulled up after accommodating the crushed material so as to facilitate collection.

Next, a method of crushing electric and electronic devices will be described. First, the inside of a water storage unit such as a water tank is filled with water. Subsequently, an explosive or pyrotechnic is suspended in the water with a wire and placed at a predetermined depth.
Electronic devices are suspended by wires and placed at a certain distance around the same depth as, for example, explosives or pyrotechnics.
An electric detonator is connected to the explosive. Then detonate the explosive or pyrotechnic with an electric detonator. When explosives or pyrotechnics explode in water, shock waves are generated in the water. The strength (maximum pressure) of this shock wave depends on the amount of the explosive, but in the vicinity of the explosive of about several cm to 1 m, several GPa to several tens MP.
a. When this shock wave acts on electrical and electronic equipment, it applies an extremely large compressive stress to electrical and electronic equipment,
Causes distortion in electrical and electronic equipment.

Since this distortion differs greatly between different kinds of materials (plastic, metal, glass, etc.), a shear force or the like is generated between different kinds of materials. Further, when a shock wave passes between different materials, some or all of the shock waves may be reflected. In this case, the phase of the shock wave is reversed at the interface between the dissimilar materials, and the stress changes from compression to tension. As a result, a strong peeling force acts between dissimilar materials. For this reason, unlike a case where a shear force acts only on a portion sandwiched between the blades by mechanical pulverization with a normal crusher or the like, cracks enter along an adhesive surface of a dissimilar material or the like and are easily peeled. .

In this way, the electric and electronic devices are crushed, and the plastic part and the metal part are separated. The crushed crushed material is stored in a collecting section such as a wire net, and the crushed material can be collected by pulling it up.

The effects exerted by the above-described embodiments will be summarized below. According to the crushing apparatus and crushing method for electric / electronic devices described in the embodiment, electric / electronic devices such as electric / electronic devices are crushed by explosion of explosives or pyrotechnics in water in the water storage unit. You. For this reason, crushing of electric and electronic devices can be easily performed by the explosive power of explosives or pyrotechnics, while avoiding the influence of explosions on the surroundings. For example,
It is possible to crush even electric and electronic devices with the plastic housing attached. In this case, a stress acts on the joint between the plastic and the metal so that the metal and the plastic are separated, and the metal and the plastic are crushed in a separated form.

Also, since the crushing is performed in water, plastics having a low specific gravity among the crushed materials float on the water surface, and metals having a high specific gravity settle, so that electrical and electronic devices can be easily separated. Yes (specific gravity sorting).

Further, since the metal and the plastic having a large specific gravity are collected by a collecting portion such as a wire mesh, and the collected crushed material has already been peeled off at the boundary between different kinds of materials, it can be easily separated and collected thereafter. Convenient to do. That is, it is easily separated by an electrostatic separation method, a magnetic force separation method or a specific gravity separation method. Therefore, when the crushed material is used as a raw material for recovering and recycling metals, baking, which is a post-process after mechanical pulverization, is not necessary, and generation of dioxins from a baking furnace can be prevented. In addition, since the crushing is performed in water and the separated and collected crushed material is also performed in a wet state, no dust is generated.

By disposing a plurality of explosives or pyrotechnics and detonating them at the same time, the power of explosions by explosives or pyrotechnics can be increased. Alternatively, by sequentially detonating explosives or pyrotechnics, it is possible to crush electric and electronic devices while suppressing noise and vibration to the surroundings.

By providing a space around the electric / electronic equipment, the degree of crushing of the electric / electronic equipment can be adjusted to be low.

Then, the electric detonator 3 is energized and the water-containing explosive 4
, 10 mobile phones 6 were crushed by the power of the explosion. Fragments of a material having a lower specific gravity than water, such as low-density plastics and paper labels, contained in the mobile phone 6 are floating near the water surface, and these debris are in the water tank 1.
Separation was easily possible by further adding water 2 to the mixture and causing it to overflow.

Fragments such as metals, printed circuit boards, and some plastics were dropped on a wire mesh 7a which had previously been submerged at the bottom of the water tank 1, and were collected by lifting the wire mesh 7a. The recovered fragments had the plastic housing broken near the joint surface. The electronic components fixed to the internal printed board by soldering were peeled off from the printed board.

Around it, 20 notebook computers 11 as electric / electronic devices (three are omitted in FIG. 2) are set so that the distance between the wet explosive 4 and the wet explosive 4 at the same depth is about 50 cm. It was hung by the wire 5b. At the bottom of the test pond 8, a wire mesh 7b supported by a wire 5c (wire rope) for collecting the crushed material of the notebook computer 11 crushed by the explosion was previously submerged.

Then, the electric detonator 3 is energized and the water-containing explosive 4
, 20 laptops 11 were crushed by the power of the explosion. Some of the plastic fragments and paper labels were lighter than water and floated near the water surface, and were easily separated by scooping the water surface with a bucket or the like.

Metal fragments and fragments such as printed circuit boards were dropped on a wire mesh 7b submerged in advance at the bottom of the water tank 1, and were collected by lifting the wire mesh 7b. After the collection, the plastic housing was broken from the vicinity of the hinges of the liquid crystal part and the main body / keyboard part. The electronic components fixed to the internal printed board by soldering were peeled off from the printed board. Glass parts constituting the liquid crystal panel were finely pulverized into powder.

The composite parts in which the metal was embedded in the plastic, the adhesive parts of the plastic and the metal, and the composite parts of the ceramic and the metal were all broken along the bonding surface and the bonding surface with the metal. For this reason, the collected fragments are separated by magnetic force,
Separation and recovery by the electrostatic separation method or the specific gravity separation method were easy. (Embodiment 3) Next, a third embodiment of the present invention will be described. FIG. 3 is a schematic cross-sectional view illustrating a configuration of a crusher for electric / electronic equipment according to the third embodiment.

The test pond 8 as a water storage unit is the same as that in the second embodiment. At the center of the test pond 8, an electric detonator 3 (commercially available No. 6 instantaneous electric detonator) was inserted at its end, and 1000 g of a water-containing explosive 4 was suspended by a wire 5a at a depth of 4 m.
Surrounding it is a large TV 1 as an electric / electronic device.
2 (not shown as one in FIG. 3) were suspended with the wire 5b so that the distance between the water-containing explosive 4 and the water-containing explosive 4 was about 80 cm at the same depth.

Also, three small televisions 13 (omitted in FIG. 3) as electric and electronic equipment are housed in a polyethylene bag 14, and a space 15 formed by air remains around the small television 13. The inner volume was adjusted and sealed. Furthermore, it was arranged around the water-containing explosive 4 so that the distance from the water-containing explosive 4 was about 80 cm. At the bottom of the test pond 8, a wire mesh 7b with a wire rope for collecting the large television 12 and the small television 13 crushed by the explosion.
Was previously submerged.

Then, the electric detonator 3 is energized and the water-containing explosive 4
, Both the large television 12 and the small television 13 were crushed by the power of the explosion. Debris from wooden enclosures, paper labels, lightweight plastic parts, etc. float near the water surface, and metal, printed circuit boards, CRTs, transformers, and other debris that could be easily collected by scooping in a bucket, etc. The wire mesh 7b was sunk into the bottom of the wire mesh 1 and stored. The wire mesh 7b was pulled up and collected. The plastic casing of the large television 12 after the recovery was broken. The electronic components fixed to the internal printed board by soldering were peeled off from the printed board. The glass parts constituting the cathode ray tube were finely pulverized into powder.

The plastic casing of the small television 13 after recovery was broken. The electronic components fixed to the internal printed board by soldering were peeled off from the printed board. The glass parts constituting the cathode ray tube were finely pulverized into powder. Since the space 15 is provided in advance, the explosive power is reduced and the size of the debris is reduced even if the plastic forming the printed circuit board and the housing is smaller than the large television 12 and the strength is small.
It was almost as good as 2.

Both televisions have composite parts in which metal is embedded in plastic, adhesive parts of plastic and metal,
Each of the ceramic and metal composite parts was broken along the bonding surface and the bonding surface with the metal. For this reason, the fragments were easily separated and collected by the electrostatic separation method, the magnetic force separation method, or the specific gravity separation method. (Embodiment 4) A fourth embodiment of the present invention will be described below. FIG. 4 is a schematic cross-sectional view illustrating a configuration of a crusher for an electric / electronic device according to a fourth embodiment. The water tank 1 as a water storage unit is the same as in the first embodiment. The water tank 1 has four sets of electric detonators 3 (a commercially available 6).
100 g of a water explosive 4 inserted into the end of the explosive 4 was suspended by a wire 5a at a depth of 1 m. In the center, a refrigerator 16 as electric and electronic equipment is installed.
The distance between the base and the water explosive 4 at the same depth as the water explosive 4 is about 10
cm. At the bottom of the test pond 8,
A wire net 7a with a frame as a collection unit for collecting the refrigerator 16 crushed by the explosion was previously submerged.

When the electric detonator 3 was energized to detonate the water-containing explosive 4, the refrigerator 16 was crushed by the explosive force acting from the surroundings. The foamed plastics used as a heat insulating material floated on the surface of the water and were easily collected by a bucket or the like.

The other pieces of the refrigerator 16 were dropped and stored on the wire mesh 7a located at the bottom of the water tank 1, and were collected by pulling up the wire mesh 7a. In the refrigerator 16 after the collection, the plastic heat insulating material portion and the metal housing were broken from near the joint surface. The electronic components fixed to the internal printed board by soldering were peeled off from the printed board. For this reason, separation and collection were easy. (Comparative Example) A mobile phone and a notebook personal computer were cut with a commercially available crusher and fragmented. Debris is cut into almost the same size depending on the shape of the blade of the crusher device and the distance between the blades.However, since the housing plastic and the internal printed circuit board are broken at the same time, the debris consists of plastic and the printed circuit board. It became a complicated entangled shape. For this reason, the debris had to be heated by a gas burner to perform a baking treatment, and the plastic portion had to be burned and removed.

The present invention may be implemented by changing the configuration of the above embodiment as follows. In the above Examples 1 to 4, the crushed material was collected using the wire meshes 7a and 7b which were previously installed at the bottom. However, the water tank 1 was lifted with a crane or the like to be turned over, and the crushed material together with the internal water 2 was collected. It is also possible to discharge and collect. Also,
