Description

  The present invention relates to a bead wire and / or steel wire recovered from a used tire (hereinafter also referred to as a waste tire), and a package of bead wire and / or steel wire that has been incinerated.

Due to the widespread use of automobiles, a large amount of waste tires are generated after the tires are used. It is no longer permissible for processors to leave them in the general living environment, social environment or natural environment in order to maintain the social life. Even in the treatment facility, it is not allowed to leave it without managing it as a large pile.
As for the disposal method of waste tires, those that can be reused such as rubber and carbon in the waste tires are reused, and those that can be easily incinerated have been incinerated. Bead wires and / or steel wires included in waste tires are not reused and have been buried as industrial waste.
Industrial waste has been processed not only in waste tires but also in a huge amount, and the embedding process has been limited in terms of location selection. Even if the waste tire burying process is continued, efforts such as at least further volume reduction are required. In the present situation aiming for a sustainable economic and industrial society, it is essential to reuse, reduce and recycle used products. Considering such a historical background, it will be necessary to use bead wires and / or steel wires contained in waste tires as raw materials.
Conventionally, there is no industrial base that accepts the collection and reuse of bead wires and / or steel wires contained in waste tires, and it has not been established as an economic act. In today's transition to a sustainable economic and industrial society, including solving resource, energy and environmental problems, we collect and actively use bead wires and / or steel wires contained in large amounts of waste tires. Technology to consider and implement is important, and the development of such technology is essential.

There are various types of tires depending on the type of vehicle to be used, such as passenger cars, motorcycles, trucks and buses, construction machines, and aircraft. A tire generally has the structure shown in FIG.
The metal part of the tire has a bead wire (1) and a belt (2). The bead wire (1) fixes the tire to the rim. The bead wire is made of a high-carbon steel and is rolled up and formed into a ring shape, and the surface thereof is plated. The belt (2) is a carcass (3: fiber layer) and tread (4: tire outer skin that prevents wear and damage), slips when water is removed on the road surface and driving force / braking force is applied. Is a reinforcing band located between two thin steel stranded wires (steel wires), rolled into a ring shape, and mounted on a carcass in a laminated state, for example 3-4 sheets (Patent Document 1). In order to withstand the use of tires that are overworked under unreasonable conditions, the metal portion is often mixed with surrounding members, and the entire tire is strong enough not to separate from each other. The bead wire accounts for 4.7% by weight and the steel wire accounts for 8.9% by weight. It can be understood that the work of collecting bead wires and steel wires for reuse is a serious task.

Let's take a look at the conventional disposal of waste tires.
The rim is removed from the tire removed from the automobile, and the tire is treated as a waste tire.
When processing waste tires, recycled tires are processed to make recycled tires, and waste tires are cut, crushed, and further crushed in some cases, and thermal recycling is performed using rubber or carbon containing metal as fuel ( Non-patent document 1). For thermal recycling, crushed tires such as 50 mm crushed tire chips and 32-part cut tires are used (FIG. 2).
Also, material recycling that recycles rubber and carbon involves cutting and crushing waste tires, separating the material into rubber and carbon and other metal parts, and then separating the material parts into rubber powder, civil engineering materials, and reinforcing agents. Used as paving material and mat material. By pulverizing, rubber, carbon, and resin are separated, and rubber, carbon, and the like are subdivided as necessary and used for reinforcing agents, paving materials, mat materials, and the like. In the case of using as rubber, after the separation and recovery as described above, the particle size is further reduced (Patent Document 2, Patent Document 3).
As described above, the recovered steel wire scrap has been buried as industrial waste. In some cases, it is also described that the recovered steel wire scrap is used as a cement reinforcing agent (Patent Document 1). For material recycling, it is an industry to recycle the processed material including the bead wire and / or steel wire and the short wire-like material made of incinerated bead wire and / or steel wire, which is to be taken up in the present invention. (Non-patent Document 1).

In the case of the conventional treatment, the waste tire is difficult to be treated as it is, except that the waste tire is reused in its original shape, and it is inconvenient to use. Cut the tire. In the case of cutting, the tire is divided into two parts and then further subdivided to have a small shape of about 32 parts (Non-Patent Document 1).
Further, in the division, the side part of the tire including the bead wire and the central part including the steel wire are cut and then further divided (Patent Document 4). In addition, a method of taking out a bead wire (Patent Document 1, Patent Document 5) is also known. These are exclusively performed in order to prevent blade spillage during the next cutting division. The steel wire is taken out as appropriate (Patent Document 6, Patent Document 7).
The bead wire from which the bead wire has been taken out may be processed as it is, but may be appropriately cut. The length of one piece is 15 to 20 cm and is further subdivided into 7 to 12 cm and 3 to 5 cm. Similarly, when the steel wire is collected, it is pulverized and subdivided to obtain a range of 10 to 12 cm, 5 to 7 cm, and the like.
When examining the object to be treated containing the short wire material made of the bead wire and / or the steel wire recovered from the recovered crushed waste tire, the short wire material made of the bead wire and / or the steel wire is examined. It can be measured as a length distribution.

As described above, the “processed material containing short wire materials made of bead wires and / or steel wires recovered from crushed waste tires” left after processing waste tires and material recycling is industrial waste. It has been processed as. It is difficult for the manufacturer to actively use this as a raw material, because the manufacturer does not think that it can be used as a raw material. It is said that.
The fuel obtained from the waste tire that is performed as thermal recycling includes a metal made of a bead wire and / or a steel wire contained in the waste tire. When used as fuel, it is carried out as part of the treatment of industrial waste, and metals and metal oxides generated from spent fuel generated at each business site that uses fuel also need to be treated as industrial waste. It becomes. Individual treatment has economic problems, and it is difficult to meet strict regulations, and it is common to take out industrial waste and treat it as industrial waste. Has been done.
The collected post-combustion bead wire and / or steel wire has undergone a heat treatment. Metals are heated, and in some cases, the components change and the characteristics become brittle.Specific components, component amounts, and shapes are unstable, and it is not possible to use them as specific raw materials. It is hard to be done. Proactively incorporating and using this as a raw material material is necessary to eliminate the anxiety of using these.

  In the treatment of waste tires, rubber, carbon, etc. that have been collected and reused in this treatment method can be collected and reused. It is evaluated from the point of effective use of points and resources / energy. However, metals and metals and metal oxides will be treated as industrial waste, which will require expenses as waste disposal costs, and will not be evaluated in this respect, and metals and metals and metal oxides will be removed. Has been criticized as an unattractive economic activity, and recovery is difficult to be an independent and sustainable system.

Against the background of the above, recovering metals recovered from waste tires that have been treated as industrial waste as part of the raw materials for metalworking, Recovering metal oxides as a part of raw materials for metal processing is important from the viewpoint of effectively using limited resources and energy, and specific measures for that purpose are needed and eagerly desired.

  The problem to be solved by the present invention includes a short wire-like substance made of bead wire and / or steel wire recovered from a crushed waste tire, which has been generated in the process of waste tire treatment and has been handled as industrial waste treatment. Use of a package for recycling a material to be treated, which is made of a bead wire and / or steel wire, which has been incinerated, and used as a raw material for a steelmaking process, a manufacturing method thereof, and a package It is to provide a steelmaking method.

The present inventors diligently researched on the above problems and found the following points.
(1) The treatment of waste tires starts from making the tires fine as described above, and the materials to be used are collected in a shape that is easy to use and recycled. Bead wires and steel wires, which are metals that are replicated along the way, have been treated as industrial waste.
(2) The reason why bead wires and steel wires, which are by-products in this process, are not recycled as iron scraps conventionally used in steel production, is considered as follows.
(B) Conventionally, what has been recovered as industrial waste is recovered including metal components that are not only waste tires but also other industrial waste. There is no guarantee that the component is specified and the component composition is constant within a certain range, and the metal manufacturer who is the user cannot use it. When not only waste tires but also metal components that are other industrial wastes are collected, it is difficult to collect industrial wastes consisting only of waste tires.
(B) Industrial waste obtained by specifying that it is the collection of waste tires is “a material to be treated containing short wires made of bead wires and / or steel wires collected from crushed waste tires, or incineration. It is a "processed object including a short thin wire substance made of processed bead wire and / or steel wire" and includes other metal processed objects to be collected, and the volume of the processed object is large. It is difficult to take out each from.
(C) “Substance to be treated containing bead wires and / or steel wires collected from crushed waste tires, or to be treated containing incinerated bead wires and / or steel wires. As a result of removing the unusable material from the `` processed product '', the resulting `` short thin wire material made of bead wire and / or steel wire, or short wire wire material made of incinerated bead wire and / or steel wire '' is lightweight. Compared with steel scrap that has been used as a raw material in steel mills, the weight and capacity are small, it is not constant, and there is no guarantee of the ingredients of the raw material. Difficult to do. Short wire materials such as bead wires and steel wires are small in weight and capacity, so when they are used as raw materials for scrap iron, they are either taken into the gas used or transported. Defects become prominent such as being unstable and unstable. In addition, even if the component is guaranteed, it is difficult to explain that the part to be sampled is not biased and is not a special part.
(3) In order to solve the problem (2), the present inventors have found that the following is effective.
(B) Processed objects containing bead wires and / or steel wires that have been collected from crushed waste tires and have been treated as industrial waste treatments, generated in the process of waste tire treatment, and Collecting a large amount of objects to be processed containing short thin wire substances made of incinerated bead wires and / or steel wires can be collected by specifying that it is a waste tire treatment.
Specifically, for example, carbon, carbon, and resin are removed from the pulverized material generated by the pulverization process of the waste tire, and the coated material containing a short wire-like substance made of bead wire and / or steel wire recovered from the crushed waste tire is used. As a processed product, it must be collected from its source and collected in large quantities.
In addition, the object to be processed containing short thin wire substances made of incinerated bead wire and / or steel wire is used after the fuel that is thermal recycling obtained by limiting the waste tire is used in a pulp factory or cement factory. Since it is left over and is not processed by the factories that use it as fuel, it must be collected and collected as processed material after it has been used as fuel for waste tires.
(B) A short thin wire substance made of bead wire and / or steel wire recovered from a crushed waste tire recovered from a crushed waste tire, or a short thin wire substance made of incinerated bead wire and / or steel wire The object to be treated contains resin, fiber, carbon in some cases, or incinerated ash.
The inclusion of these resins, fibers, carbon, or incineration ash is most disliked because it affects the purity of the product in some cases. By using magnetic means, it is possible to obtain a short thin wire substance made of a bead wire and / or a steel wire, or a short thin wire substance made of an incinerated bead wire and / or a steel wire, and a short wire made of a bead wire or a steel wire. If it is limited to thin wire substances, its components and component amounts can be specified, sampling based on them can be performed without bias, or the resulting components and component amounts are guaranteed. It is possible to guarantee the grounds and results for quality assurance of the separated items.
(C) After the short thin wire substance made of bead wire and / or steel wire or the short thin wire substance made of incinerated bead wire and / or steel wire is separated by magnetic means, a certain force is applied by mechanical means. The drum can can be filled in a dense state while being added, and then the drum can is reduced in volume by compressing and sealing the drum can, so that the drum can is made of a tightly packed bead wire and / or steel wire. It is possible to obtain a package made of a material, or a short thin wire substance made of a bead wire and / or a steel wire that has been incinerated.
(D) It is made of a short thin wire substance made of a bead wire and / or a steel wire, or an incinerated bead wire and / or a steel wire, packed in a drum can, obtained as described above. The package can be supplied as iron scrap to a melting process such as an electric furnace or cupola in a steelmaking process. It must be safe to use as a recycled material because it has a constant composition as iron scrap, which is a raw material, and a weight and capacity capable of stable operation in foundries and electric furnace steelmaking plants.

According to the present invention, “a to-be-processed object including a bead wire and / or steel wire recovered from a crushed waste tire, or an incinerated bead wire and / or steel wire is processed. A package comprising a short thin wire substance made of a bead wire and / or a steel wire filled in a drum can, or a short thin wire substance made of an incinerated bead wire and / or a steel wire. Can be obtained.
This packaging body has a constant composition as iron scrap as a raw material in a casting manufacturing factory and an electric furnace steelmaking factory, and has a weight and capacity capable of stable operation, and can be used safely as a recycled raw material. .

  The present invention relates to an object to be treated containing a bead wire and / or steel wire collected from a crushed waste tire, or an object to be treated containing an incinerated bead wire and / or steel wire. After separating the short thin wire substance made of bead wire and / or steel wire from the object, or the short thin wire substance made of incinerated bead wire and / or steel wire by magnetic means, the drum can be filled by mechanical means, A package in which a drum can is compressed and sealed, and a reduced linear drum can be filled with a short thin wire made of bead wire and / or steel wire, or a short thin wire made of incinerated bead wire and / or steel wire. Is the body.

  The object to be treated in the present invention was collected from a crushed waste tire (1) an object to be treated containing a short wire-like substance composed of a bead wire and / or a steel wire, or a crushed waste tire. Later (2) A to-be-processed object including a short thin wire substance made of incinerated bead wire and / or steel wire.

(1) An object to be processed containing a short wire-like substance made of a bead wire and / or a steel wire recovered from a crushed waste tire is (i) an object to be processed containing a short wire-like substance made of a bead wire, and (b) a steel wire. Or (b) a workpiece containing a short thin wire substance made of a bead wire and a steel wire.
According to the method of processing the crushed waste tire, or according to the way of collecting the objects to be processed, the one according to the above classification can be obtained.

(A) A method for obtaining an object to be processed containing a short thin wire substance made of a bead wire is as follows.
Since the bead wire is strong, in some cases, only the bead wire is taken out. The bead wire is taken out from the portion including the bead wire, cut as necessary, and bound (FIG. 4).
The processing of the waste tire including the bead wire and the steel wire without taking out the bead wire from the portion including the bead wire will be described later in (c).
The method of carving the waste tire into the part including the bead wire and the part including the steel wire is performed by a cutter. Various methods have been invented for an apparatus for separating a portion including a bead wire from a tire in a waste tire (Japanese Patent Publication Nos. 56-5658, 53-34235, and 2003-205521). The basic operation is to fix the waste tire and cut it with a cutter.
With respect to taking out the bead wire from the part including the bead wire and taking out the bead wire from the part including the bead wire in an operation of cutting the bead wire, there is a device (Japanese Patent No. 3009891) that applies a force to the bead wire and pulls it out. An apparatus and method for separating and removing a bead wire by high-frequency heating or induction heating is also known (Japanese Patent Laid-Open No. 2003-205521). In this case, it is supposed that only the bead wire can be collected. In this case, it is stated that the metal can be reused or recycled to be recycled (the same publication 0012). In view of the fact that the bead wires collected by this method are collected and recycled, the individual wires have a small capacity and light weight, and it is troublesome to simply recycle these wires. Is in a state that cannot be performed stably.

(B) A method for obtaining an object to be processed containing a short thin wire substance made of steel wire is as follows.
After the bead wire portion is cut and removed according to (a) above, the steel wire is taken out from the portion including the steel wire, and the steel wire is cut to obtain an object to be processed containing a short thin wire substance made of the steel wire. (Similar to (i) above). Without taking out the steel wire from the part containing the steel wire, it can be crushed and pulverized to obtain an object to be treated containing a short thin wire substance of the steel wire and a part containing rubber or carbon. When the material is separated, it is possible to obtain an object to be processed containing a short thin wire substance of steel wire (FIG. 5).
Also, when taking out from a steel belt waste tire, it is known that a tire divided into 16 equal parts in the radial direction can be subjected to high-frequency heating in a high-frequency induction heating furnace, and the steel wire can be pulled out and taken out (Japanese Patent Laid-Open No. 6-1994). No. 121977). When it is taken out by this method, it is described that the steel wire is used as a secondary material for reinforcing concrete (0014), but it is not conscious to recycle and use it as a raw material for the metal steel manufacturing process.
From the point of view of cycle use, it means that the capacity is small as in (a) above, and the bead wire itself is light weight, and the bead wire recovered at this stage is reused and recycled. It is impossible.

(C) An object to be processed containing a short thin wire substance made of a bead wire and a steel wire.
The waste tire is divided, and the crushed waste tire is made into a part containing bead wire and steel wire, and this is crushed, and the treated object containing the bead wire and steel wire short thin wire substance and the part containing rubber and carbon What is to be processed can be obtained by separating this to obtain an object to be treated containing short-wire substances of bead wires and steel wires (right side of FIG. 6). The portion containing rubber or carbon is shown on the left side of FIG.
The length of the collected thin wire substances of the bead wire or the steel wire can be estimated by sampling the collected materials and measuring the length distribution of the short wire substances.
It can be seen that the objects to be processed including the short wire-like material made of the bead wire and the steel wire collected from the crushed waste tire are mixed with various things depending on the processing contents. The most notable points are that there are variations in the length of the collected thin wire material consisting of bead wire and steel wire, and the case in which the rubber or carbon that has been crushed and separated is separated in the workpiece. However, it is considered that it is necessary to guarantee the properties, weight and capacity, and the composition of the ingredients that cannot be separated and various fibers are mixed and used as they are as part of the steel raw material. It can be said that it is impossible.
The lengths of the collected bead wires and steel wires can be grasped by measuring the length distribution from those actually collected from those collected.
The bead wires include those in the range of 15 to 20 cm, 10 to 12 cm, 5 to 8 cm, and the like.
Steel wires include those in the range of 10 to 12 cm, 5 to 8 cm, and the like.
About 1 to 3% by weight of rubber, carbon, and various fibers that could not be separated.

(2) The objects to be treated including short thin wire substances made of bead wires and / or steel wires obtained by incinerating waste tires are as follows.
An object to be treated comprising a bead wire and / or a steel wire composed of a short thin wire substance, which is a subject of incineration of a waste tire to be treated according to the present invention, is a waste tire obtained by crushing a waste tire and possibly further crushing it. This is industrial waste that is left after combustion of a piece of fuel (obtained as thermal recycling) in a combustion apparatus such as a boiler. Fuel consisting of tire pieces is used in the state where bead wires and steel wires or steel wires remain, and the residue includes these bead wires and steel wires or steel wires that have been heat-treated in an oxidized state. . And, deposits and incineration ash are accompanied by incineration.
Although the form of the fuel is still a waste tire part, the size of the tire piece varies. The 32 divided pieces may have a piece exceeding 15 cm. In the case of a 20 mm piece, it is about 20 mm.
As described above, the fuel to be thermally recycled is obtained by dividing a waste tire into 32 parts, a 50 mm crushed tire and a 20 mm crushed tire.
The incinerated bead wires include those in the range of 10 to 12 cm and 5 to 8 cm.
Incinerated steel wires include those in the range of 10 to 12 cm and 5 to 8 cm.
The content of incineration ash is about 0.1% by weight.
An example is as shown in FIG.

The process for producing the package of the present invention comprises the following two processes.
(1) The first step is as follows.
To-be-treated material containing bead wires and / or steel wires collected from crushed waste tires, or to-be-treated materials containing bead wires and / or steel wires made by incineration of used tires Separating the short thin wire substance made of bead wire and / or steel wire, or the short thin wire substance made of incinerated bead wire and / or steel wire from this process. In the object to be processed containing the fibrous substance, it is a step of removing the coherent substance such as rubber, carbon, fiber, etc., and taking out the short thin line substance made of the bead wire and / or the steel wire. The target substance to be taken out is a bead wire and / or a steel wire, and it is effective to use magnetic means. When using magnetic means, the bead wire may be removed in the original long state when the bead wire is removed. In this case, even if the bead wire is long, If it can be filled as it is, it can be filled as it is (the length is the length embedded in the tire). This can be used by cutting to a required length as appropriate. Usually, there are many in the range of 15 to 20 cm, 10 to 12 cm, 5 to 8 cm, and the like. This is appropriately cut in consideration of ease of handling. If this length is a fine length of about 2 cm or less, it may not be appropriate for separation by electromagnet processing. Steel wire may have been taken out in its original long state, and in this case, even if it is in a long state, it can be filled as it is if it can be filled in a drum can as it is, If necessary, it can be cut into a required length and used. Usually, there are many in the range of 10 to 12 cm, 5 to 8 cm, and the like. This is appropriately cut in consideration of ease of handling. If this length is a fine length of about 2 cm or less, it may not be appropriate for separation by electromagnet processing.
The object to be treated is stimulated by vibrations due to transportation, movement, etc., and contaminants such as rubber, carbon, and fiber are easily separated, and the bead wire and / or steel wire is adsorbed by energizing the electromagnet. As a result, contaminants such as rubber, carbon, and fibers are separated. In addition, this separation step also serves to transport a short thin wire substance made of a bead wire and / or a steel wire to a position where the drum can is filled. However, there is a case where a foreign matter such as rubber, carbon, or fiber is intertwined with the bead wire and / or the steel wire and cannot be sufficiently separated. In that case, if the amount is not large, it does not affect the component composition in the end, so it may be mixed.
This process is important for removing incineration ash and substances adhering to the surface of treated objects containing short thin wire substances consisting of bead wires and / or steel wires that have been incinerated from waste tires. is there.
The target substance to be taken out is a bead wire and / or a steel wire, and it is effective to use magnetic means. When using magnetic means, it is particularly effective that bead wires are in the range of 10 to 12 cm, 5 to 8 cm, etc., and steel wires are in the range of 10 to 12 cm, 5 to 8 cm, etc., and can be separated using an electromagnet. Works. This depends on the size of the fuel used as fuel by crushing the waste tire. The object to be treated is stimulated by vibrations due to transportation, movement, etc., and the incinerated ash and substances adhering to the surface are easily separated. By energizing the electromagnet, the bead wire and / or steel wire is adsorbed. As a result, the incineration ash and substances adhering to the surface are separated. In addition, this separation step also serves to transport a short thin wire substance made of a bead wire and / or a steel wire to a position where the drum can is filled.
Also in this case, if the length is too small, separation may not be performed well.
When separated from the electromagnet, the bead wire and / or the steel wire is sampled to determine how much is contained and estimated to determine the amount.
The above process is shown in FIG.

(2) The second step is as follows.
The short thin wire substance made of the bead wire and / or the steel wire separated in the first step of (1) or the short thin wire substance made of the incinerated bead wire and / or the steel wire is made into a continuous machine. The drum can is filled by a suitable means, and the drum can is compression-sealed to form a reduced volume drum package.
The drum can is used by opening the lid of the used drum can. As an automated mechanical means, when filling, it can be performed by operating a jumbo (trade name: a hydraulic shovel). By using a jumbo, it is possible to fill a drum can in a dense state while applying a certain force to a short thin wire substance made of a bead wire and / or a steel wire. In some cases, while being transported by a belt conveyor, a short thin line material can be taken out by magnetic means and filled into a drum can.
The above process is shown in FIG.
For example, when a bead wire and / or a steel wire short thin wire substance collected from a crushed waste tire is separated by magnetic means and then filled into a drum can by mechanical means, 110 kg to 120 kg per drum can It may become. Normally, about 1/3 of the capacity of the drum can is crushed (the capacity becomes 2/3) (FIG. 9). In some cases, it may be less.
Also, in this case, when the incinerated bead wires and / or steel wires are separated by magnetic means and then filled into drums by mechanical means, 200 kg per drum can There is.
Usually, the capacity of the drum can is reduced by about 1/3 to 1/2 (the capacity is reduced from 2/3 to 1/2) (FIG. 9).

A package obtained by filling a drum can with a short thin wire material made of bead wire and / or steel wire, or a short thin wire material made of incinerated bead wire and / or steel wire, and compressing and sealing the drum can is as follows. Can be supplied as a raw material to the steelmaking process (FIGS. 10 and 11).
For example, although it depends on the operation status of the steelmaking factory, the operation of the factory requires about 20 to 30 tons per day. In order to use this in a steel factory, it is necessary to constantly supply such an amount. If it is the package of the present invention, it is possible to supply an amount that satisfies these supply amounts, but if it is not a package, the bead wire and / or the steel wire will be enormous in volume and will be difficult to supply. It is.
It can be used as iron scrap, which is a raw material with high purity that can be used in steelmaking production. The capacity and weight are constant, and stable operation is possible compared to the case of using conventional iron scrap.
