以下、本発明を実施する上で好適な実施例について図面を用いて説明する。なお、各図面において、同一の構成については同一の符号を付し、重複する部分についてはその詳細な説明は省略する。また、下記はあくまでも実施例に過ぎず、発明の内容は下記態様に限定されるものでないことは言うまでもない。   Hereinafter, preferred embodiments for carrying out the present invention will be described with reference to the drawings. In the drawings, the same components are denoted by the same reference numerals, and detailed description of the overlapping portions is omitted. In addition, the following is merely an example, and it goes without saying that the content of the invention is not limited to the following embodiment.

図1および図2を参照して、実施例1の破砕方法および破砕装置について説明する。図1はノズルとチゼルを別々に2か所配置し、固形物などの破砕対象物を破砕する装置構成を示す概要図である。図2はノズルとチゼルを別々に2か所配置して破砕し、破砕片の形状および大きさ(寸法)を制御している概要図である。図1,図2に示すように、本実施例ではノズル2とチゼル(Chisel)3を備えた破砕装置1を複数設置し、破砕片7の形状および大きさを制御しながら破砕を行うことが特徴である。   With reference to FIG. 1 and FIG. 2, the crushing method and crushing apparatus of Example 1 are demonstrated. FIG. 1 is a schematic diagram showing an apparatus configuration for crushing a crushing object such as a solid material by arranging two nozzles and a chisel separately. FIG. 2 is a schematic view in which the nozzle and the chisel are separately arranged at two locations and crushed to control the shape and size (size) of the crushed pieces. As shown in FIGS. 1 and 2, in this embodiment, a plurality of crushing apparatuses 1 having nozzles 2 and chisel 3 are installed, and crushing is performed while controlling the shape and size of the crushing pieces 7. It is a feature.

具体的には破砕対象4に対し、破砕したい大きさ(寸法)の両端2か所に破砕装置1を図1のように設置し、破砕装置1を用いて両端2か所に破砕を行う。また、破砕片の形状を制御する場合は、各々のノズル2とチゼル(Chisel)3を所望の形状に合わせて連続的に移動(線移動)または断続的に移動(点移動)させ、破砕片の形状を制御する。そして、この破砕装置1に挟まれた部分を一体として破砕することで、図2に示すように任意の形状と大きさ(寸法)に破砕片4を加工することが出来る。   Specifically, the crushing device 1 is installed at two places on both ends of the size (dimension) to be crushed as shown in FIG. In addition, when controlling the shape of the crushed pieces, each nozzle 2 and chisel 3 are continuously moved (line movement) or intermittently moved (point movement) according to the desired shape, and the crushed pieces are moved. Control the shape. And by crushing the part pinched | interposed into this crushing apparatus 1 as one body, as shown in FIG. 2, the crushing piece 4 can be processed into arbitrary shapes and magnitude | sizes (dimensions).

この際、ウォータジェットWJは、破砕対象4に連続的に噴射してもよく、また断続的に噴射してもよい。破砕対象4の剛性(硬さ)や厚み、所望する破砕片7の形状や大きさ(寸法)に応じて連続的または断続的噴射する。   At this time, the water jet WJ may be continuously injected to the object to be crushed 4 or may be intermittently injected. Depending on the rigidity (hardness) and thickness of the object 4 to be crushed and the desired shape and size (size) of the crushed piece 7, continuous or intermittent injection is performed.

また、破砕対象4に噴射するウォータジェットWJの水量や水圧、噴射角度、噴射時間についても、破砕対象4の剛性(硬さ)や厚み、所望する破砕片7の形状や大きさ(寸法)に合せて設定する。   Further, the water amount, water pressure, spray angle, and spray time of the water jet WJ sprayed onto the crushing object 4 also depend on the rigidity (hardness) and thickness of the crushing object 4 and the desired shape and size (dimensions) of the crushing piece 7. Set together.

このように任意の形状、大きさ(寸法)に破砕片を制御することで破砕片を回収容器に入る形状と寸法で破砕が可能なため、破砕片を容器に入れて回収することが容易となる。また、破砕片を一定の形状と大きさ(寸法)に破砕することが可能になり、破砕した後の破砕片の加工や処理が容易になる。   By controlling the crushed pieces in any shape and size (dimension) in this way, the crushed pieces can be crushed with the shape and size that fits into the collection container, so that the crushed pieces can be easily collected in the container. Become. In addition, the crushed pieces can be crushed into a certain shape and size (dimension), and processing and processing of the crushed pieces after being crushed becomes easy.

図3を参照して、実施例2の破砕方法および破砕装置について説明する。図3はノズル、チゼル、バキュームおよび飛散防止カバー(回収カバー)5を配置し、回収カバー内で破砕片を吸引している様子を示す概要図である。   With reference to FIG. 3, the crushing method and crushing apparatus of Example 2 are demonstrated. FIG. 3 is a schematic view showing a state in which a nozzle, a chisel, a vacuum, and an anti-scattering cover (collection cover) 5 are arranged and the crushed pieces are sucked in the collection cover.

本実施例の破砕装置は、ダスト飛散(破砕片7の飛散)を抑えつつ破砕片7を回収する目的で図3に示すような飛散防止カバー(アラミド繊維等や伸縮機構付の金属製等)内に破砕装置(ノズル2およびチゼル3)およびバキューム6を設置し、破砕片を吸引しながら破砕する。図3ではアラミド繊維のカバーを一例として記載している。その他の例として、破砕対象との接触部に、例えばスポンジを取り付けた容器を被せてカバーとしても良い。なお、ウォータジェットWJを噴射した水量以上にバキューム6で吸引し、飛散防止カバー5内部の水によってカバーが外れることを防ぐようにしてもよい。   The crushing apparatus of the present embodiment is a scattering prevention cover (such as an aramid fiber or a metal with an expansion / contraction mechanism) as shown in FIG. 3 for the purpose of collecting the crushing pieces 7 while suppressing dust scattering (spattering of the crushing pieces 7). A crushing device (nozzle 2 and chisel 3) and a vacuum 6 are installed inside, and the crushing pieces are crushed while being sucked. In FIG. 3, an aramid fiber cover is shown as an example. As another example, it is good also as a cover by covering the contact part with the crushing object, for example, the container which attached sponge. It is also possible to suck the water jet WJ more than the amount of water injected by the vacuum 6 and prevent the cover from being removed by the water inside the scattering prevention cover 5.

このように飛散防止カバー(回収カバー)により破砕時の周囲に破砕片が飛び散ったりダストが飛散したりするのを防止し、さらにバキューム機構を設けることで、破砕片を効率的に回収することができる。   In this way, the shatter prevention cover (recovery cover) prevents shattering pieces and dust from scattering around the shattering, and by providing a vacuum mechanism, the shattered pieces can be efficiently recovered. it can.

図4から図7を参照して、実施例3の破砕方法および破砕装置について説明する。図4はウォータジェット流路8をチゼル3の内部に内包する流路内包チゼルと破砕対象を示す概要図である。図5は流路内包チゼルの上下振動により破砕対象にひび割れが生じさせる様子を示す概要図である。図6は流路内包チゼルの上下振動で生じさせたひび割れに高圧水を噴射している様子を示す概要図である。また、図7は流路内包チゼルにより破砕対象を吹き飛ばしている様子を示す概要図である。   The crushing method and crushing apparatus of Example 3 will be described with reference to FIGS. FIG. 4 is a schematic view showing a flow path enclosing chisel that encloses the water jet flow path 8 inside the chisel 3 and a target to be crushed. FIG. 5 is a schematic view showing a state in which cracks are generated in the object to be crushed by the vertical vibration of the flow channel inclusion chisel. FIG. 6 is a schematic view showing a state in which high-pressure water is injected into a crack generated by vertical vibration of the flow channel inclusion chisel. FIG. 7 is a schematic view showing a state in which the object to be crushed is blown away by the flow channel inclusion chisel.

本実施例の破砕方法では、先ず図4に示すように、破砕対象4の破砕したい位置に流路内包チゼル(ウォータジェット流路8およびチゼル3)を配置する。次に、図5に示すように、チゼル3により破砕対象4にひび割れを生じさせる。そして、図6に示すように、チゼル3と破砕対象4が密着して生じた閉空間に対してウォータジェットWJを噴射し、図7に示すように、破砕対象4を破砕する。   In the crushing method of the present embodiment, first, as shown in FIG. 4, the flow channel inclusion chisel (the water jet flow channel 8 and the chisel 3) is disposed at the position where the crushing object 4 is desired to be crushed. Next, as shown in FIG. 5, cracks are generated in the object 4 to be crushed by the chisel 3. And as shown in FIG. 6, the water jet WJ is injected with respect to the closed space which the chisel 3 and the crushing object 4 produced, and crush the crushing object 4 as shown in FIG.

本実施例の破砕方法によれば、流路内包チゼルにより、チゼル単独やウォータジェット単独では破砕できない破砕対象を効率よく破砕することができる。   According to the crushing method of the present embodiment, the crushing target that cannot be crushed by the chisel alone or the water jet alone can be efficiently crushed by the flow channel inclusion chisel.

図8は図4から図7に示した流路内包チゼルの変形例である。上記で説明した破砕対象の破砕方法において、図8に示すノズルとチゼルを別々に設置した破砕装置を用いることも可能である。つまり、単独のチゼルおよび単独のノズルの組み合せで破砕装置を構成してもよい。この場合、先ず破砕対象4の破砕したい位置にチゼル3を配置する。次に、チゼル3により破砕対象4にひび割れを生じさせる。そして、破砕対象4に生じたひび割れに対してウォータジェットWJを噴射し、破砕対象4を破砕する。この場合も、チゼル単独やウォータジェット単独では破砕できない破砕対象を効率よく破砕することができる。   FIG. 8 is a modified example of the flow path enclosing chisel shown in FIGS. In the crushing method for crushing object described above, it is also possible to use a crushing apparatus in which the nozzle and the chisel shown in FIG. 8 are separately installed. That is, the crushing device may be configured by a combination of a single chisel and a single nozzle. In this case, the chisel 3 is first arranged at the position where the object 4 to be crushed is to be crushed. Next, the chisel 3 causes a crack in the object 4 to be crushed. And the water jet WJ is injected with respect to the crack which arose in the crushing object 4, and the crushing object 4 is crushed. Also in this case, it is possible to efficiently crush an object to be crushed that cannot be crushed by a chisel alone or a water jet alone.

なお、上記では、チゼル3による衝撃力で破砕対象4にひびを入れて、そこにウォータジェットWJの噴流で破砕対象4を破砕するメカニズムを想定して説明したが、ウォータジェットWJの噴流で破砕対象4にひびを入れた箇所にチゼル3の衝撃力で破砕対象4を破砕するメカニズムでも同様にチゼル単独やウォータジェット単独では破砕できない破砕対象を効率よく破砕することができる。   In the above description, the mechanism is described in which the fracture target 4 is cracked by the impact force of the chisel 3 and the fracture target 4 is fractured by the jet of the water jet WJ. Similarly, the mechanism of crushing the crushing object 4 with the impact force of the chisel 3 at the cracked part of the object 4 can efficiently crush the crushing object that cannot be crushed by the chisel alone or the water jet alone.

また、チゼル3の衝撃力を破砕対象4に加えることと、ウォータジェットWJの噴流を破砕対象4に噴射することが同時に処理されても同様に本発明の効果を得ることができる。   Further, even if the impact force of the chisel 3 is applied to the crushing object 4 and the jet of the water jet WJ is jetted onto the crushing object 4, the effects of the present invention can be obtained similarly.

図9Aから図9Cを参照して、実施例4の破砕方法および破砕装置について説明する。図9Aは刃物型のチゼルを複数配置して破砕対象を破砕する例を示す斜視図である。また、図9Bは図9AのA−A’矢視図であり、図9Cはチゼル3が流路内包チゼルであることを示す断面図である。   The crushing method and crushing apparatus of Example 4 will be described with reference to FIGS. 9A to 9C. FIG. 9A is a perspective view showing an example of crushing an object to be crushed by arranging a plurality of blade-type chiseles. 9B is a cross-sectional view taken along the line A-A ′ of FIG. 9A, and FIG. 9C is a cross-sectional view showing that the chisel 3 is a flow channel enclosing chisel.

実施例1から実施例3の各実施例では、チゼルの断面形状が円形状または略円形状のものを想定して図示しているが、図9Aおよび図9Bに示すように、チゼルの形状を刃物型としてもよい。チゼル3の形状を刃物型にすることで、破砕する方向を正確に制御可能となる。この場合、図9A,図9Bのようにウォータジェットノズルをチゼル内に内包する流路内包チゼルとしてもよく、刃物型のチゼル3とノズル2を個別に設置してもよい。   In each of the first to third embodiments, the chisel has a circular or substantially circular cross-sectional shape. However, as shown in FIGS. 9A and 9B, the chisel has a shape. It is good also as a blade type. By making the shape of the chisel 3 into a blade shape, the direction of crushing can be accurately controlled. In this case, as shown in FIGS. 9A and 9B, the water jet nozzle may be a channel-containing chisel that encloses the water jet nozzle in the chisel, or the blade-type chisel 3 and the nozzle 2 may be individually installed.

図10および図11を参照して、実施例3で説明した破砕方法をステップで説明する。図10はチゼルで破砕対象にひびを入れた後にウォータジェットで破砕する方法を示し、図11はウォータジェットで破砕対象にひびを入れた後にチゼルで破砕する方法を示している。   With reference to FIG. 10 and FIG. 11, the crushing method demonstrated in Example 3 is demonstrated in steps. FIG. 10 shows a method of crushing with a water jet after cracking an object to be crushed with a chisel, and FIG. 11 shows a method of crushing with a chisel after cracking an object to be crushed with a water jet.

本発明による破砕方法は、図10に示すように、先ず、チゼルの衝撃力で破砕対象にひびを入れる。(ステップS1)
次に、破砕対象のひびに対してノズルによりウォータジェットを連続的または断続的に噴射する。(ステップS2)
ステップS2を一定時間継続または断続的に繰り返すことにより、破砕対象が破砕される。(ステップS3)
また、図11の方法では、先ず、ノズルによるウォータジェットを連続的または断続的に噴射して破砕対象にひびを入れる。(ステップS1’)
次に、破砕対象のひびに対してチゼルにより衝撃力を加える。(ステップS2’)
ステップS2’を一定時間継続または断続的に繰り返すことにより、破砕対象が破砕される。(ステップS3’)
以上説明した各実施例によれば、破砕片を回収容器に入る形状および大きさ(寸法)に破砕可能なため、破砕後の破砕片の回収や加工、処理が容易になる。また、破砕時に周囲への破砕片やダストの飛散を抑制しつつ、破砕片を回収できるため、ダスト飛散による汚染拡大を防止することができる。
As shown in FIG. 10, the crushing method according to the present invention first cracks the crushing object with the impact force of the chisel. (Step S1)
Next, a water jet is sprayed continuously or intermittently by a nozzle to the crack to be crushed. (Step S2)
The object to be crushed is crushed by repeating step S2 for a certain period of time or intermittently. (Step S3)
In the method of FIG. 11, first, a water jet by a nozzle is ejected continuously or intermittently to crack the object to be crushed. (Step S1 ′)
Next, an impact force is applied to the cracks to be crushed by a chisel. (Step S2 ')
By repeating step S2 ′ continuously or intermittently for a certain period of time, the object to be crushed is crushed. (Step S3 ′)
According to each embodiment described above, since the crushed pieces can be crushed into a shape and size (dimensions) entering the collection container, collection, processing, and processing of the crushed pieces after crushing are facilitated.
