Description

本発明は、ゴム製タイヤを廃棄する場合において、ウォータージェットで破砕する装置及びその方法に関するものである。
The present invention relates to an apparatus and a method for crushing with a water jet when a rubber tire is discarded.

廃タイヤは、スリップ防止や氷結防止を目的とするアスファルトへの混入、コンクリートの充填材など再資源化効率の高い素材を多く含み、種々の方法によって処理されている。例えば、切断刃を回転させて細かく切断する方法、高温のジェットフレームを噴射させて細粒化させる方法、冷凍してクラッシャーで粉砕する方法などがある。また、廃タイヤを処理する場合、スチールベルトやタイヤの内周部のビード部に埋め込まれているビードワイヤも破砕すると、ゴム片とワイヤ片の分離が困難となる。このため、高周波で熱を加えながらワイヤ類を分離したり、ビードワイヤを強制的に引き抜いて取り除くなどの前工程を行ってから処理する方法が採られている。
特開２０００−３１７３３５ 特開昭５３−０３６５２８号 Waste tires contain many materials with high recycling efficiency, such as mixing in asphalt for the purpose of preventing slipping and freezing, and concrete fillers, and are treated by various methods. For example, there are a method of cutting finely by rotating a cutting blade, a method of spraying a high-temperature jet frame to make fine particles, a method of freezing and crushing with a crusher. Moreover, when processing a waste tire, if the bead wire embedded in the bead part of the inner peripheral part of a steel belt or a tire is also crushed, it will become difficult to isolate | separate a rubber piece and a wire piece. For this reason, a method is employed in which a wire is separated while applying heat at a high frequency, or a pre-process such as forcibly pulling out and removing the bead wire is performed.
JP 2000-317335 A JP 53-036528

廃タイヤをそのまま破砕する場合、ビードワイヤの存在によりカッタを傷めやすく危険を伴うし、上述したように破砕後のゴム片とワイヤ片を分離する工程が必要となる。ジェットフレームなど高温で廃タイヤを処理する方法では、熱によるゴムの変質やガスの発生、さらにビードワイヤの劣化をも伴い再利用できなくなる問題がある。また、ビードワイヤを強制的に引き抜く方法ではビードワイヤが切断されやすく再資源としての価値が著しく低下する。しかもタイヤに残ったスチールベルトやビードワイヤの除去、ワイヤ類に付着したゴム片の除去など多大な手間を要する欠点があった。
When the waste tire is crushed as it is, the presence of the bead wire is liable to damage the cutter, and there is a risk of separating the rubber piece and the wire piece after crushing as described above. In the method of treating waste tires at a high temperature such as a jet frame, there is a problem that the rubber cannot be reused due to deterioration of the rubber due to heat, generation of gas and deterioration of the bead wire. In addition, the method of forcibly pulling out the bead wire easily cuts the bead wire, and the value as a resource is significantly reduced. In addition, there are drawbacks that require a great deal of labor, such as removal of steel belts and bead wires remaining on the tire, and removal of rubber pieces adhering to the wires.

そこで本発明者は上記問題に鑑み鋭意研究の結果、本発明を成し得たものであり、その特徴とするところは、ゴムタイヤをウォータージェットによって破砕する装置の発明であって、破砕処理するゴムタイヤをほぼ水平にして差し込んで支持する逆Ｔ字状の支持部材と、周面の一部に軸方向の開口部を有し該支持部材で支持したゴムタイヤを収納する円筒状のカバー部材と、該カバー部材の開口部側方に設けたウォータージェットのノズルと、該支持部材を回転させる回転装置とによって構成したこと。   Accordingly, the present inventor has achieved the present invention as a result of diligent research in view of the above problems, and the feature of the present invention is an apparatus for crushing a rubber tire with a water jet, and the rubber tire to be crushed An inverted T-shaped support member that is inserted and supported substantially horizontally, a cylindrical cover member that has an opening in the axial direction in a part of the peripheral surface thereof, and stores a rubber tire supported by the support member; A water jet nozzle provided on the side of the opening of the cover member and a rotating device for rotating the support member.

ゴムタイヤをウォータージェットによって破砕する方法の発明であって、径φ１．０〜φ５．０mmのノズルにより、圧力７０〜１７５ＭＰａ、流量３０liter／分以上でウォータージェットを噴出させること。或いは、破砕処理する複数のゴムタイヤを逆Ｔ字状の支持部材に差し込んで支持し、これを周面の一部に軸方向の開口部を有する円筒状のカバー部材の内部に装填した後、該カバー部材の底部に設けた回転装置で該支持部材を回転させながら、該カバー部材の開口部側方に設けたノズルからウォータージェットを噴出させることにある。   The invention relates to a method of crushing a rubber tire with a water jet, wherein the water jet is jetted at a pressure of 70 to 175 MPa and a flow rate of 30 liter / min or more by a nozzle having a diameter of φ1.0 to φ5.0 mm. Alternatively, a plurality of rubber tires to be crushed are inserted into and supported by an inverted T-shaped support member, and this is loaded into a cylindrical cover member having an axial opening in a part of the peripheral surface. A water jet is ejected from a nozzle provided on the side of the opening of the cover member while the support member is rotated by a rotating device provided at the bottom of the cover member.

さらに、複数のゴムタイヤを連続的に破砕処理するための工程の発明であって、周面の一部に軸方向の開口部を設けた円筒状のカバー部材の内部にほぼ水平に積み重ねたゴムタイヤを、該カバー部材の開口部側方に配したノズルによってウォータージェットで破砕する破砕装置、該破砕装置で破砕したゴムタイヤ破砕片の乾燥装置、該破砕片の粒度を選別する分別装置、及び破砕に利用した液体を循環させるための処理装置、処理した液体を高圧にして該ノズルに供給する高圧ポンプとによって構成したことにある。   Furthermore, the invention is a process for continuously crushing a plurality of rubber tires, and a rubber tire stacked substantially horizontally inside a cylindrical cover member provided with an axial opening in a part of the peripheral surface. , A crushing device for crushing with a water jet by a nozzle disposed on the side of the opening of the cover member, a drying device for crushing rubber tire pieces crushed by the crushing device, a sorting device for selecting the particle size of the crushing pieces, and a crushing device A processing apparatus for circulating the liquid and a high-pressure pump that supplies the nozzle with the processed liquid at a high pressure.

ここで、本明細書中でいう「支持部材」とは、受部に挿通部を立設した逆Ｔ字状のものであり、該挿通部にゴムタイヤを嵌め込んで受部で支持する構造の部材をいう。通常、支持部材に複数のゴムタイヤを嵌め込んで支持した状態でウォータージェットによる破砕処理を行う。   Here, the “support member” in the present specification is an inverted T-shaped member in which an insertion portion is erected in the receiving portion, and has a structure in which a rubber tire is fitted into the insertion portion and supported by the receiving portion. Refers to a member. Usually, the crushing process by a water jet is performed in a state where a plurality of rubber tires are fitted and supported on the support member.

「カバー部材」とは、ゴムタイヤを支持した支持部材を収納するための円筒状の部材をいう。本発明においては、支持部材で支持したゴムタイヤの側方からウォータージェットで破砕処理するため、カバー部材の周面の一部に軸方向の開口部を設けている。そして、カバー部材の底部に支持部材を回転させるための回転装置を設け、ゴムタイヤを回転させながらウォータージェットを噴出させて破砕する。   The “cover member” refers to a cylindrical member for housing a support member that supports a rubber tire. In the present invention, an axial opening is provided in a part of the peripheral surface of the cover member in order to perform a crushing treatment with a water jet from the side of the rubber tire supported by the support member. A rotating device for rotating the support member is provided at the bottom of the cover member, and a water jet is spouted and crushed while rotating the rubber tire.

支持部材はカバー部材の内部に設け、回転装置で直接回転させる構造としてもよいが、回転装置に載置することによって回転させる構造としてもよい。この場合には、カバー部材の外部で支持部材にゴムタイヤを装着し、これをユンボやクレーンなどで吊り上げてカバー部材内部の回転装置に設置する。このようにすれば、破砕処理中に平行して他の支持部材にゴムタイヤの装着作業を行うことができ作業能率が向上する。   The support member may be provided inside the cover member and directly rotated by the rotating device, or may be rotated by being placed on the rotating device. In this case, a rubber tire is attached to the support member outside the cover member, and this is lifted by a yumbo or a crane and installed in a rotating device inside the cover member. By doing so, it is possible to perform the work of attaching the rubber tire to the other support member in parallel during the crushing process, and the work efficiency is improved.

基本的には、カバー部材の開口部側方部に設けたノズルからウォータージェットを噴出させ、支持部材を回転させながら破砕処理を行うが、ターンテーブルに複数のカバー部材を設け、該ターンテーブルを回転させることによって、各カバー部材の開口部をノズル位置に位置させる構造としてもよい。このようにすれば、大量のゴムタイヤを処理する場合に有用となる。また、複数種径の異なるカバー部材をターンテーブル上に配することで、大型トラックのタイヤや軽自動車のタイヤなど種々大きさの異なるゴムタイヤでも、連続して破砕処理することが可能となる。   Basically, the water jet is ejected from a nozzle provided on the side of the opening of the cover member, and the crushing process is performed while rotating the support member. However, the turntable is provided with a plurality of cover members. It is good also as a structure which positions the opening part of each cover member in a nozzle position by rotating. This is useful when processing a large amount of rubber tires. In addition, by disposing a plurality of types of cover members having different diameters on the turntable, it is possible to continuously crush even rubber tires having various sizes such as tires for large trucks and light automobiles.

本発明におけるウォータージェットによるゴムタイヤの破砕においては、ノズル径を比較的大きくし、圧力を低くすると共に流量を多くする。これにより、タイヤ内に設けられているスチールベルトを破砕することなく、ゴム質部分のみを破砕若しくは粉砕することができ、ワイヤ類の分離も容易となる。
タイヤの種類や大きさによって異なるが、噴出口がφ１．０〜φ５．０mmのノズルを用い、７０〜１７５ＭＰａの圧力で、３０liter／分以上の流量でウォータージェットを噴出させる。 In the crushing of the rubber tire by the water jet in the present invention, the nozzle diameter is relatively large, the pressure is lowered, and the flow rate is increased. Thereby, only the rubber-like part can be crushed or crushed without crushing the steel belt provided in the tire, and the wires can be easily separated.
Although depending on the type and size of the tire, a water jet is ejected at a flow rate of 30 liters / minute or more at a pressure of 70 to 175 MPa using a nozzle having a diameter of φ1.0 to φ5.0 mm.

ゴムタイヤを破砕若しくは粉砕する場合、ノズルを往復運動させたり、円軌道を描くように回転させながらウォータージェットを噴出させてもよく、ノズルの向きを調整できるように設けてもよい。ノズルの噴出口の径、及びノズルの上下動や回転速度と、回転装置によるゴムタイヤの回転速度の組み合わせにより、５０μ〜５cm２程度に破砕若しくは粉砕することができる。ノズルを往復運動させる速度は約０．７ｍ／ｓ〜７ｍ／ｓ。ノズルを回転させる場合は回転半径２０mm〜１２０mmで１００〜６００ｒｐｍ程度である。また、ゴムタイヤは０．５〜８ｒｐｍ程度で回転させる。 When the rubber tire is crushed or pulverized, the nozzle may be reciprocated, or the water jet may be ejected while rotating so as to draw a circular orbit, and the direction of the nozzle may be adjusted. Depending on the combination of the diameter of the nozzle outlet, the vertical movement and rotation speed of the nozzle, and the rotation speed of the rubber tire by the rotating device, it can be crushed or crushed to about 50 μm to 5 cm 2 . The speed at which the nozzle is reciprocated is about 0.7 m / s to 7 m / s. When the nozzle is rotated, the rotation radius is about 20 to 120 mm and about 100 to 600 rpm. The rubber tire is rotated at about 0.5 to 8 rpm.

一般的に、ウォータージェットによるゴムタイヤの破砕においては、水、軽油、重油などの液体を高圧（４０〜２５０ＭＰｓ程度）で噴出させることによって行うが、液体を循環させることで一つのシステムとして稼働させることができる。例えば、本発明破砕装置と、破砕片の乾燥装置、破砕片の大きさによって選り分ける分別装置、そしてウォータージェットに利用した液体の処理装置、処理した液体を高圧にするための高圧ポンプとによって破砕システムを構成する。
Generally, rubber tires are crushed by water jets by ejecting liquids such as water, light oil, and heavy oil at high pressure (about 40 to 250MPs), but operating as a system by circulating the liquid. Can do. For example, the crushing apparatus of the present invention, the crushing piece drying apparatus, the sorting apparatus that sorts by the size of the crushing piece, the liquid processing apparatus used for the water jet, and the high-pressure pump for increasing the pressure of the processed liquid Configure the system.

本発明に係るゴムタイヤ破砕装置及びその方法は、支持部材で支持したゴムタイヤを、円筒状のカバー部材に収納した状態で、回転させながら側方からウォータージェットを噴出させることにより、該ゴムタイヤを簡単・確実に破砕でき、複数のゴムタイヤを連続的に破砕することも可能となる。また、ノズルの往復運動させたり回転させることによりゴムタイヤを任意の大きさに破砕若しくは粉砕することができ、燃料や二次製品などとして活用できる処理が可能となる。本発明によるウォータージェット破砕方法では、圧力を低くして流量を多くすることにより、ゴムタイヤ内のワイヤ類を切断することなく取り出すことができ、ゴム片との分離が極めて容易となる。しかも熱などによる劣化が生じないため各種再生物としてリサイクルさせることができる。   The rubber tire crushing apparatus and method according to the present invention is a rubber tire that is simply supported by rotating a water tire from a side while rotating the rubber tire supported by a support member in a cylindrical cover member. It can be reliably crushed and a plurality of rubber tires can be crushed continuously. Further, the rubber tire can be crushed or pulverized to an arbitrary size by reciprocating or rotating the nozzle, and processing that can be utilized as fuel, secondary products, or the like becomes possible. In the water jet crushing method according to the present invention, by reducing the pressure and increasing the flow rate, the wires in the rubber tire can be taken out without being cut, and separation from the rubber piece becomes extremely easy. Moreover, since it does not deteriorate due to heat or the like, it can be recycled as various recycled materials.

ウォータージェットに使用する液体を循環使用することにより、ウォータージェット発生装置や水処理装置などの破砕処理システムをトラックに積載して移動することができ、工場内だけでなく現場に赴いての作業も可能となる。このため、処理すべき廃タイヤの輸送コストが軽減し、しかも現場地域内での活用、消費が可能となる。また、破砕によりタイヤ容積が約２０％程度となり、廃タイヤの保管スペースを縮小できる効果が生じる。さらに、液体の循環使用により現地に公害等の影響を及ぼさないなど極めて有益な効果を有するものである。
By circulating and using the liquid used in the water jet, crushing processing systems such as water jet generators and water treatment devices can be loaded on the truck and moved, and not only in the factory but also in the field. It becomes possible. For this reason, the transportation cost of the waste tire which should be processed can be reduced, and also the utilization and consumption within a field area are attained. Moreover, the tire volume becomes about 20% by crushing, and the effect that the storage space of a waste tire can be reduced arises. Furthermore, it has extremely beneficial effects such as not causing pollution and other effects on the site by circulating the liquid.

本発明は、ゴムタイヤを逆Ｔ字状の支持部材に支持し、軸方向の開口部を有するカバー部材に収納した状態で、該ゴムタイヤを回転させながらその側方からウォータージェットを噴射させる。そして、ウォータージェットの圧力を低く流量を多くすることで、ワイヤ類を切断することなく破砕処理することを実現した。
In the present invention, a rubber tire is supported by an inverted T-shaped support member, and in a state where the rubber tire is housed in a cover member having an axial opening, a water jet is jetted from the side of the rubber tire while rotating. And, by reducing the pressure of the water jet and increasing the flow rate, it was possible to perform the crushing process without cutting the wires.

The nozzle N is provided in the moving device 4 so as to be movable up and down, and processes from the waste tire T at the lower end. The support member 2 of the present example has a structure in which a plurality of waste tires T are supported and lifted by a crane or the like and placed on the rotating device 32 inside the cover member 3 for storage. Generally, the waste tire T is rotated at about 1 rpm, and the nozzle N is crushed while reciprocating at 1 m / s.

本例の廃タイヤＴの破砕においては、４８０ＨＰのポンプで、径φ２．６mmのノズルＮから９０ＭＰａ、１２０liter／分のウォータージェットを噴出させている。   In crushing the waste tire T of this example, a water jet of 90 MPa and 120 liter / min is ejected from a nozzle N having a diameter of 2.6 mm by a pump of 480 HP.
