Description

本発明は、主として廃タイヤや廃キャタピラ等において、ワイヤーや連結基板等の金属部分等を残して他の構成部材を粉状物とする搬送式粉砕装置に関するものである。   TECHNICAL FIELD The present invention relates to a conveying type pulverizing apparatus that uses other components as powders, mainly in waste tires, waste caterpillars, and the like, leaving metal parts such as wires and connecting substrates.

廃タイヤの粉砕手段としては従前より種々提案されているが、廃タイヤを非分割状態で粉砕する手段としては、ジェットバーナ又はジェットバーナを使用した蒸気ジェットを使用する手段（特許文献１：特開昭５５−１６２３８７号）や、ウォータージェットを使用する手段（特開２００５−４６７５８号）が知られている。   Various types of waste tire grinding means have been proposed in the past. However, as means for grinding a waste tire in an undivided state, a jet burner or a means using a steam jet using a jet burner (Patent Document 1: Japanese Patent Laid-Open Publication No. 2003-151867) No. 55-162387) and means using a water jet (Japanese Patent Laid-Open No. 2005-46758) are known.

特許文献１に記載されている粉砕装置は、ホッパー状の処理タンク内に複数本の廃タイヤを投入し、タンク頂部に設けた蒸気ジェットでタンク内のタイヤの粉砕を行うようにしており、所定の粉砕が終了すると、タンク内に残ったビートワイヤーやスチールコードをタンク下方より取り出すようにしている。   The pulverizing apparatus described in Patent Document 1 is configured to put a plurality of waste tires into a hopper-shaped processing tank and to pulverize the tires in the tank with a steam jet provided at the top of the tank. When the pulverization is finished, the beat wire and steel cord remaining in the tank are taken out from below the tank.

特許文献２記載の粉砕装置は、上下方向に積層したタイヤの下方位置で、タイヤに対して径φ１〜５ｍｍのノズルから高圧水を噴射し、水と混濁した粉砕物を搬出分離するものであり、積層タイヤの粉砕が終了すると、残余のビートワイヤーやスチールコードを積層箇所から取りはずすようにしている。   The pulverization apparatus described in Patent Document 2 is for discharging high-pressure water from a nozzle having a diameter of φ1 to 5 mm to a tire at a lower position of the tires stacked in the vertical direction, and carrying out and separating the pulverized material turbid with water. When the pulverization of the laminated tire is completed, the remaining beat wire and steel cord are removed from the laminated portion.

前記の特許文献１，２に記載されている粉砕処理装置は、粉砕対象物の連続供給による連続粉砕ではなく、所定量毎の単位体処理となっている。従って各単一体の処理毎に、金属部分の除去、廃タイヤの供給、分離装置（固気・固液）の再作動を繰り返すもので、連続作業が望ましい装置の自動化の点から問題がある。   The pulverization apparatus described in Patent Documents 1 and 2 is not continuous pulverization by continuous supply of pulverized objects, but unit body processing for each predetermined amount. Accordingly, every single unit treatment involves repeated removal of metal parts, supply of waste tires, and re-operation of the separation device (solid-gas / solid-liquid), which is problematic in terms of automation of a device where continuous operation is desirable.

また特に特許文献１記載の粉砕装置は、火焔ジェットバーナによる粉砕は、高温処理となって粉砕された粉末が炭化してしまうので、２００〜３００℃の過熱蒸気ジェットで粉砕する手段を提案したもので、これは１台のジェットバーナで複数個のタイヤを粉砕するような、大型のバーナ体を採用したため、粉砕処理タンク内の高温化が避けられなかった結果によるものである。   In particular, the pulverizing apparatus described in Patent Document 1 proposes a means for pulverizing with a superheated steam jet at 200 to 300 ° C. because the pulverized powder is carbonized due to high-temperature processing when pulverizing with a flame jet burner. This is because a high-temperature burner body that pulverizes a plurality of tires with a single jet burner is used, and thus the temperature inside the pulverization tank cannot be avoided.

しかし近年のジェットバーナにおいては、音速２〜３以上のジェット噴射流を得ることができ、口径２ｃｍ程度のノズル口からのジェット噴射流をタイヤに当てると、その高速衝撃によって半径１０ｃｍ程度の半球状範囲で一瞬にして微粉末化され、しかも直接高温に曝されるのではなく衝撃力による粉砕であり、炭化することなく微粉末化することが可能となる。   However, in a recent jet burner, a jet jet flow with a sound speed of 2 to 3 or more can be obtained. When a jet jet flow from a nozzle opening having a diameter of about 2 cm is applied to a tire, the high-velocity impact causes a hemispherical shape with a radius of about 10 cm. The powder is pulverized in an instant within a range, and is not directly exposed to high temperature but pulverized by impact force, and can be pulverized without carbonization.

そこで本発明は、音速以上のジェット噴射流を採用して、連続作業による粉砕を実現する搬送式粉砕装置を提案したものである。   In view of this, the present invention proposes a conveying crushing apparatus that employs a jet jet flow at or above the speed of sound to realize crushing by continuous work.

本発明に係る搬送式粉砕装置は、搬送コンベアの移動部に、密封構造とした粉砕処理通路に形成すると共に、粉砕処理通路における入口側及び出口側に２段の密封ゲートを設けて導入室と排出室を形成し、前記導入室と排出室との間に粉砕処理室を形成し、粉砕処理室上方に圧縮空気と燃料を供給して点火燃焼させてノズル口から音速以上の高温ジェット流として下向きに噴射させるバーナ体を適宜数、適宜位置に設けると共に、微粉末吸引口を設けてなる粉砕処理機構部と、導入室に所定の時間毎に粉砕対象物を送りこむ原料供給機構部と、粉砕処理室の微粉末吸引口に接続される粉体分離部及び吸引ファンを備えてなる分離機構部とで構成したことを特徴とするものである。   The conveying crushing apparatus according to the present invention is formed in a crushing processing passage having a sealed structure in a moving part of a conveying conveyor, and is provided with a two-stage sealing gate on the inlet side and the outlet side in the crushing processing passage, A discharge chamber is formed, a pulverization processing chamber is formed between the introduction chamber and the discharge chamber, and compressed air and fuel are supplied above the pulverization processing chamber and ignited and combusted, so that a high-temperature jet flow higher than the speed of sound is generated from the nozzle opening. An appropriate number of burner bodies to be sprayed downward are provided at an appropriate position, and a pulverization processing mechanism part provided with a fine powder suction port, a raw material supply mechanism part for sending an object to be pulverized into the introduction chamber every predetermined time, and pulverization It is characterized by comprising a powder separation part connected to a fine powder suction port of the processing chamber and a separation mechanism part provided with a suction fan.

また特に窒素発生機構を別設し、粉砕処理室にジェット噴射流と共に窒素ガスを供給するようにしてなるものである。   In particular, a nitrogen generating mechanism is separately provided, and nitrogen gas is supplied to the pulverization processing chamber together with the jet jet flow.

而してバーナ体に点火してノズル口より燃焼ガスを噴射させ、同時に吸引ファンを作動させて粉砕処理室にジェット噴射流と共に窒素ガスを供給し、この状態で原料供給機構部から粉砕対象物（例えば廃タイヤ等）を外側ゲートのみを開放して導入室に供給し、外側ゲートを閉じた後、内側ゲートを開放すると、粉砕処理対象物は、搬送コンベアの移動によって粉砕処理室に入る。そして粉砕対象物が粉砕処理室に入ると導入室の内側ゲートは閉じて、次の処理対象物の導入室への供給準備状態とする。   Thus, the burner body is ignited to inject combustion gas from the nozzle port, and at the same time, the suction fan is operated to supply nitrogen gas together with the jet injection flow into the pulverization processing chamber. When the outer gate is opened after only the outer gate is opened and the inner gate is opened after the outer gate is closed, the object to be crushed enters the pulverization chamber by the movement of the conveyor. When the object to be pulverized enters the pulverization processing chamber, the inner gate of the introduction chamber is closed to prepare for supply of the next object to be processed to the introduction chamber.

粉砕処理室に移動した粉砕処理対象物は、音速以上の高温ジェット噴射流の衝撃波を受けて所定の範囲が瞬時に微粉末化される。従って粉砕処理室の移動の期間において、高温ジェット噴射流を受ける位置がずれるようにしておくことで、廃タイヤのような大きな処理対象物も完全に微粉化がなされる。   The object to be pulverized, which has moved to the pulverization chamber, is instantly pulverized within a predetermined range upon receiving a shock wave of a high-temperature jet jet flow at or above the speed of sound. Accordingly, by shifting the position of receiving the high-temperature jet jet flow during the movement of the pulverization processing chamber, even a large processing object such as a waste tire is completely pulverized.

粉砕処理室の微粉末は、吸引ファンによる吸引作用で、吸引口から分離機構部に送られ、微粉体が分離される。   The fine powder in the pulverization chamber is sent to the separation mechanism from the suction port by the suction action by the suction fan, and the fine powder is separated.

粉末化されない残渣（廃タイヤの場合には、ビートワイヤーやスチールコード等）は、排出室の直前まで移動すると、排出室内側ゲートが開放して排出室に入り、内側ゲートが閉塞された後に外側ゲートが開放して残渣を排出するものである。   Residues that are not powdered (in the case of waste tires, such as beet wires and steel cords) move to just before the discharge chamber, the gate inside the discharge chamber opens and enters the discharge chamber, and the outer gate is closed The gate is opened to discharge the residue.

従って粉砕対象物（廃タイヤ等）を所定の間隔で順次供給することで、微粉化処理がなされると共に、窒素ガスを常時供給し、粉砕処理室への処理対象物の導入ならびに残渣の排出に際して二重ゲートを採用し、非酸素状態で雰囲気中の微粉化処理を行うことで、粉塵爆発の発生を防止したものである。   Therefore, pulverization processing is performed by sequentially supplying objects to be crushed (waste tires, etc.) at predetermined intervals, and nitrogen gas is constantly supplied to introduce the object to be pulverized into the pulverization chamber and discharge the residue. Dust explosion is prevented by adopting a double gate and pulverizing the atmosphere in a non-oxygen state.

尚廃タイヤ・廃キャタピラ等の粉塵爆発の虞が無い対象物の場合には、窒素ガス供給を行わなくても良い。   In the case of an object that does not have the possibility of dust explosion, such as waste tires and waste caterpillars, it is not necessary to supply nitrogen gas.

本発明は上記の構成を採用したものであるから、廃タイヤのような大きな処理対象物や、廃キャタピラのように大きな金属製連結基板の表面にゴム質材を設けた部材のように不定形で金属部分が多い複雑な形状のものでも、処理対象物の形態に応じてバーナ体の配置を決定することで、容易に微粉末処理が可能であり、且つ残渣が存在する粉砕対象物であっても、連続的な処理が実現できたものである。   Since the present invention adopts the above-described configuration, it is indefinite like a large processing object such as a waste tire or a member provided with a rubber material on the surface of a large metal connecting substrate such as a waste caterpillar. Even if it has a complicated shape with many metal parts, it can be easily pulverized by determining the arrangement of the burner body according to the form of the object to be processed, and it is an object to be crushed with residues. However, continuous processing can be realized.

次に本発明の実施の形態について説明する。実施形態に示した搬送式粉砕装置は、粉砕処理対象物として廃タイヤＡの場合を例にしたものである。   Next, an embodiment of the present invention will be described. The conveyance type pulverization apparatus shown in the embodiment is an example in which the waste tire A is used as an object to be pulverized.

実施形態の粉砕装置は、搬送機構部１と、粉砕処理機後部２と、原料供給機構部３と、分離機構部４と、残渣排出機構部５とで構成される。   The pulverization apparatus according to the embodiment includes a transport mechanism unit 1, a pulverizer rear unit 2, a raw material supply mechanism unit 3, a separation mechanism unit 4, and a residue discharge mechanism unit 5.

搬送機構部１は、耐熱構造で所定の速度で移動する搬送コンベア１１及びその駆動機構１２で構成されるものである。   The transport mechanism unit 1 includes a transport conveyor 11 that moves at a predetermined speed with a heat-resistant structure and a drive mechanism 12 thereof.

粉砕処理機構部２は、前記搬送コンベア１１の搬送移動範囲において、コンベア下方に密封板を配置し、且つコンベア上方を覆うようにして粉砕処理通路２１を形成し、粉砕処理通路２１における入口側及び出口側に２段の密封ゲート（入口ゲート２２，出口ゲート２３）を設けて、導入室２１１と排出室２１２を形成し、前記導入室２１１と排出室２１２との間に粉砕処理室２１３を形成したものである。   The pulverization processing mechanism section 2 forms a pulverization processing path 21 so as to cover the upper part of the conveyor, and a sealing plate is disposed below the conveyor in the transfer movement range of the transfer conveyor 11. A two-stage sealed gate (inlet gate 22 and outlet gate 23) is provided on the outlet side to form an introduction chamber 211 and a discharge chamber 212, and a pulverization chamber 213 is formed between the introduction chamber 211 and the discharge chamber 212. It is a thing.

前記の粉砕処理室２１３には、バーナ体２４と、微粉末吸引口２５を設けたもので、バーナ体２４は、周面を空冷又は液冷構造とした燃焼室に、高圧空気と燃料を供給し、点火燃焼させ、燃焼ガスをノズル口（径φ２ｃｍ程度）から噴射させるもので、噴射流は高温（１３３０℃〜２０００℃）で音速以上（マッハ２〜３）のジェット噴射流とするもので、搬送コンベア１１に向けて上方から下方に噴射する。このバーナ体２４は、搬送コンベア１１の進行方向に添って適宜数・適宜位置（粉砕対象物である廃タイヤＡがジェット噴射流で粉末化される範囲に対応して定められる）に設けたものである。勿論バーナ体２４には、コンプレッサー（高圧空気供給源）や燃料供給機構が付設されている。   The pulverization chamber 213 is provided with a burner body 24 and a fine powder suction port 25. The burner body 24 supplies high-pressure air and fuel to a combustion chamber whose peripheral surface is air-cooled or liquid-cooled. The combustion gas is ignited and the combustion gas is injected from the nozzle port (diameter of about φ2 cm). The injection flow is a jet injection flow at a high temperature (1330 ° C. to 2000 ° C.) and above the speed of sound (Mach 2 to 3). Then, it is sprayed downward from above toward the conveyor 11. This burner body 24 is provided in an appropriate number and appropriate position along the traveling direction of the conveyor 11 (determined corresponding to the range in which the waste tire A that is the object to be pulverized is pulverized by the jet spray) It is. Of course, the burner body 24 is provided with a compressor (high pressure air supply source) and a fuel supply mechanism.

微粉末吸引口２５は、粉砕処理室２１３内の微粉末Ｂ全体を吸引できるようにフード構造に形成したものである。   The fine powder suction port 25 is formed in a hood structure so that the whole fine powder B in the pulverization chamber 213 can be sucked.

更に窒素発生機構２６を別設して、粉砕処理室２１３にジェット噴射流と共に、或いは単独で窒素ガスＥを供給するようにしてなる。   Further, a nitrogen generating mechanism 26 is provided separately, and the nitrogen gas E is supplied to the pulverization processing chamber 213 together with the jet spray flow or alone.

原料供給機構部３は、搬送コンベア１１の搬入位置まで廃タイヤＡを搬送する供給コンベア３１と、供給コンベア３１で運搬されてきた廃タイヤＡを導入室２１１に押し込む押し込み機構（油圧シリンダーなどで形成される）３２とで構成したものである。   The raw material supply mechanism 3 includes a supply conveyer 31 that conveys the waste tire A to the carry-in position of the conveyer 11 and a push-in mechanism (formed by a hydraulic cylinder or the like) that pushes the waste tire A conveyed by the supply conveyor 31 into the introduction chamber 211. 32).

分離機構部４は、微粉末吸引口２５と接続したもので、側方から噴出して渦流となり固形物は自重で下方に沈下し、気体は中央上部から取り出す構造のサイクロン型分離部４１，と、フィルター部４２と、吸引ファン４３とで構成される。   The separation mechanism unit 4 is connected to the fine powder suction port 25, and is ejected from the side to become a vortex, the solid matter sinks downward due to its own weight, and the cyclone type separation unit 41 having a structure in which the gas is taken out from the upper center, The filter unit 42 and the suction fan 43 are configured.

残渣排出部５は、搬送コンベア１１の搬出側に配設したものであり、残渣Ｃを装置外にコンベア等で搬出する構成を採用しているものである。   The residue discharge part 5 is arrange | positioned at the carrying-out side of the conveyance conveyor 11, and employ | adopts the structure which carries out the residue C with a conveyor etc. out of an apparatus.

而して入口ゲート２２及び出口ゲート２３を閉塞した状態で、搬送コンベア１１を動作させ、バーナ体２４を点火して、粉砕処理室２１３にジェット噴射流Ｄを噴出すと共に窒素ガスＥを供給し、同時に吸引ファン４３を作動させる。   Thus, the conveyor 11 is operated with the inlet gate 22 and the outlet gate 23 closed, the burner body 24 is ignited, the jet flow D is ejected into the pulverization processing chamber 213, and the nitrogen gas E is supplied. At the same time, the suction fan 43 is operated.

そしてこの状態で原料供給機構部３の供給コンベア３１から一定の間隔で粉砕対象物である廃タイヤＡが送られて、所定位置（入口ゲート２２前）にくると、入口ゲート２２の外側ゲート２２ａが開放され、廃タイヤＡは、押し込み機構３２で速やかに導入室２１１内の搬送コンベア１１上に押し出され、前記外側ゲート２２ａが閉じられる（図４イ、ロ）。   In this state, when the waste tire A, which is an object to be crushed, is sent from the supply conveyor 31 of the raw material supply mechanism unit 3 at regular intervals and comes to a predetermined position (before the entrance gate 22), the outer gate 22a of the entrance gate 22 is reached. Is released, and the waste tire A is quickly pushed out onto the conveyor 11 in the introduction chamber 211 by the push-in mechanism 32, and the outer gate 22a is closed (FIG. 4A, B).

廃タイヤＡが導入室２１１内に位置すると、入口ゲート２２の内側ゲート２２ｂが開放され、廃タイヤＡは、搬送コンベア１１で粉砕処理室２１３に運ばれ、導入室２１１は空室となると、内側ゲート２２ｂが閉じて、次の廃タイヤＡの供給待機状態となる。そして順次廃タイヤＡは粉砕処理室２１３内に送り込まれ、この送り込みに際しては、前記の導入室２１１を設けることによって、粉砕処理室２１３内の微粉末Ｂ並びに充満している窒素ガスが外に漏れでることを防止しているものである。   When the waste tire A is located in the introduction chamber 211, the inner gate 22b of the entrance gate 22 is opened, and the waste tire A is transported to the pulverization processing chamber 213 by the conveyor 11, and when the introduction chamber 211 becomes empty, The gate 22b is closed and the next waste tire A is ready for supply. Then, the waste tire A is sequentially fed into the pulverization chamber 213, and when this is introduced, the introduction chamber 211 is provided so that the fine powder B in the pulverization chamber 213 and the filled nitrogen gas leak out. It is what prevents it.

粉砕処理室２１３内では、搬送コンベア１１で移動する廃タイヤＡに対して、バーナ体２４のノズル口からの音速以上の高温ジェット噴射流Ｄが吹き付けられ、ジェット噴射流Ｄの衝撃波によって、廃タイヤＡの所定の範囲部分は、瞬時に微粉末化される。   In the pulverization chamber 213, a high-temperature jet jet D higher than the sound speed from the nozzle opening of the burner body 24 is blown against the waste tire A moving on the conveyor 11, and the waste tire is generated by the shock wave of the jet jet D. A predetermined range portion of A is instantly pulverized.

この粉砕処理室２１３内の移動の間、廃タイヤＡの各部分はジェット噴射流Ｄの噴射を受けるので、廃タイヤＡのような大きな処理対象物であっても完全に微粉化がなされる。   During the movement in the pulverization chamber 213, each portion of the waste tire A receives jet jet D, so that even a large processing object such as the waste tire A is completely pulverized.

更に粉砕処理室２１３内の微粉末Ｂは、吸引ファン４３による吸引作用で、吸引口２５から分離機構部４に送られ、微粉末Ｂは、気体と分離される。   Further, the fine powder B in the pulverization chamber 213 is sent to the separation mechanism unit 4 from the suction port 25 by the suction action by the suction fan 43, and the fine powder B is separated from the gas.

分離機構部４では、サイクロン型分離部４１において、微粉末Ｂは自重でサイクロン下方に沈下堆積し、サイクロン型分離部４１の底部から取り出されることになり、更にフィルター部４２で気体中から微粉末Ｂが完全に除去されることになる。そしてこの廃タイヤＡの微粉末Ｂは、再度タイヤ原料として使用できるものである。   In the separation mechanism unit 4, the fine powder B sinks and accumulates under the cyclone under its own weight in the cyclone type separation unit 41, and is taken out from the bottom of the cyclone type separation unit 41. Further, the fine powder B is extracted from the gas by the filter unit 42. B will be completely removed. The fine powder B of the waste tire A can be used again as a tire raw material.

粉砕処理室２１３内におけるジェット噴射流によって粉末化されない残渣（ビートワイヤーやスチールコード等）Ｃは、そのまま搬送コンベアで搬送されることになるので、排出室２１２の直前まで移動すると、排出室２１２を区切る出口ゲート２３の内側ゲート２３ｂが開放し、残渣Ｃは、排出室２１２に入り、直ぐに内側ゲート２３ｂが閉塞され、その後外側ゲート２３ａが開放して残渣Ｃは、搬送コンベア１１外に排出される。   Residues (beat wires, steel cords, etc.) C that are not pulverized by the jet flow in the pulverization chamber 213 are transported as they are by the transport conveyor. The inner gate 23b of the outlet gate 23 to be separated is opened, the residue C enters the discharge chamber 212, the inner gate 23b is immediately closed, and then the outer gate 23a is opened and the residue C is discharged out of the transport conveyor 11. .

搬送コンベア１１から排出された残渣Ｃは、残渣排出部５によって適宜な処理場所に搬出されることになる。   The residue C discharged from the conveyor 11 is carried out to an appropriate processing place by the residue discharge unit 5.

従って前記の廃タイヤの粉砕処理は、大きな廃タイヤをそのままの状態から連続的に微粉末化を行うことができたものである。   Therefore, the pulverization treatment of the above-mentioned waste tire can continuously pulverize a large waste tire as it is.

また本発明装置は前記の廃タイヤ以外にも複雑な形状をした連結基板の接地面部分にゴム被覆した廃キャタピラ片についても、金属製の連結基板が残渣として残り、再生部品として使用するこができる。   In addition to the waste tire described above, the apparatus of the present invention can also be used as a recycled part for the waste caterpillar piece with rubber coating on the ground contact surface portion of the connection board having a complicated shape. it can.

また本発明は、粉塵爆発の危険がない処理対象物においては、窒素ガスの供給の必要が無いものであり、他の種々の粉砕対象処理物の粉砕を行うことができるものである。   Further, according to the present invention, it is not necessary to supply nitrogen gas in a processing object that is free from the risk of dust explosion, and other various processing objects to be pulverized can be pulverized.
