【発明の詳細な説明】 ゴム含有廃棄物の再加工のための処理方法本発明はゴム含有廃棄物の再加工のた めの処理方法に関する。[Detailed description of the invention] Process for reprocessing rubber-containing waste The present invention provides a method for reprocessing rubber-containing waste. Concerning how to dispose of rice.

古ゴム、自動車タイヤ、例えば窓やドア、中でも自動車のそれらの補強材入りゴ ムパツキン、オイル用ホースのようなゴム含有ホース等のゴム含有廃棄物は今日 一般に後での再加工や再利用のために多かれ少なかれ予備的に細分割される。Old rubber, car tires, such as windows and doors, especially rubber with reinforcing materials in cars. Today, rubber-containing waste such as rubber-containing hoses, such as oil hoses, It is generally subdivided more or less preliminarily for later reprocessing or reuse.

その後でこの廃棄物は更に部分的に処理されるが、その際それら廃棄物の個々の 構成成分を分離することが試みられる。すなわち各ゴム質構成部材に加えてなお 鉄その他の金属類、鋼線又は鉄線、合成樹脂、繊維類、フリース等が存在する場 合がある。This waste is then further partially treated, with individual Attempts are made to separate the components. In other words, in addition to each rubber component, Where iron or other metals, steel wire or iron wire, synthetic resin, fibers, fleece, etc. are present. There is a case.

ゴム含有廃棄物をグラインダーの中で磨砕し、又は粉砕すること力松知であるが 、その際その廃棄物は予め、また同時的に冷却又は深冷してその冷却したゴムの 砕けやすさを利用し、そして中でもそのゴムの加硫や場合により存在する合成樹 脂類の融解混合を防止する。中でもそのゴムの砕けやすさもこの廃棄物の冷却に よって高められてそれによりこのゴムは金属性構成成分から容易に分離すること ができる。この場合に、中でも金属質の各構成部材がゴム及びその他の構成部　 。Grinding or pulverizing rubber-containing waste in a grinder is a In that case, the waste is cooled or deep-cooled in advance and at the same time, and the cooled rubber is Taking advantage of its friability and, among other things, the vulcanization of its rubber and the possible presence of synthetic trees. Prevents melting and mixing of fats. Among other things, the brittleness of the rubber is also useful for cooling this waste. The rubber is thus enhanced so that it can be easily separated from the metallic components. Can be done. In this case, each metallic component is replaced by rubber and other components. .

加により行われる。It is carried out by addition.

グラインダーから出てくる個々の構成成分の混合物は次に分離される。その際例 えば鉄片は磁石を用いて吸着分離される。！！ｌ維質等は場合により吸い出し分 離される。個々の構成成分からなる混合物はまた、篩い分けによって分離するこ ともできる。The mixture of individual components coming out of the grinder is then separated. Example For example, pieces of iron are attracted and separated using a magnet. ! ! l Fibre, etc. may be sucked out depending on the case. be separated. Mixtures of individual components can also be separated by sieving. You can also do it.

しかしながら、グラインダーはその作業空間内に非常に大きな容積を有し、その ために例えば液体窒素等の冷却媒体を非常に多量に添加しなければならない。However, the grinder has a very large volume within its working space and its For this purpose, very large amounts of cooling medium, such as liquid nitrogen, must be added.

従って本発明の課題は、ゴム含有廃棄物を再加工のために処理する方法において 、エネルギー消費を節約でき、そして例えば窒素のような冷却媒体を僅かしか必 要としない方法を提供することである。The object of the invention is therefore to provide a method for treating rubber-containing waste for reprocessing. , saves energy consumption and requires less cooling medium, e.g. nitrogen. The aim is to provide a method that does not require

この課題は請求の範囲第１項に記載した方法によって解決される。このゴム含有 廃棄物の再加工のための処理方法においてはそのゴム含有廃棄物をスクリュープ レスの中で圧壊し、そしてこの廃棄物は少なくともそのスクリュープレスの中で 冷却される。This problem is solved by the method according to claim 1. This rubber content In the treatment method for waste reprocessing, the rubber-containing waste is crushed in the press, and this waste is crushed at least in the screw press. cooled down.

本発明に従う方法によって液体窒素又はその他の冷却媒体の消費量は公知の方法 においてグラインダー等の中での磨砕に際して従来必要であった冷却媒体の量よ りも５０％よりもはるかに僅かな量まで低下し、と言うのはそれら廃棄物のスク リュープレス中での各廃棄物片の間の自由空間が非常に強く減少し、そして僅か な容積％までにさえ減少するからである。スクリュープレスの中で特に金属性構 成成分が他の種々の構成成分と分離される。ゴムも合成樹脂成分及び／又は繊維 成分がゴムと分離される程に強力に圧壊され、プレスされる。The consumption of liquid nitrogen or other cooling medium by the method according to the invention is determined in a known manner. The amount of cooling medium that was conventionally required for grinding in a grinder etc. The amount of waste is reduced by much less than 50%, which means that the waste The free space between each waste piece in the Liupress is reduced very strongly and only slightly This is because it decreases even to a small volume %. Among screw presses, metal construction is particularly important. The components are separated from various other components. Rubber is also a synthetic resin component and/or fiber The components are crushed and pressed so strongly that they are separated from the rubber.

本発明に従う方法の第１の実施態様によれば、その廃棄物に冷却のために液体窒 素を添加混合する。窒素は−１９５，８℃の沸点を有する。液体窒素を利用する ことによって、廃棄物物質を約−１２（１’Ｃまで冷却することができる。この ものはそのスクリュープレスから約５０℃の温度で排出される。According to a first embodiment of the method according to the invention, the waste is heated with liquid nitrogen for cooling. Add and mix the ingredients. Nitrogen has a boiling point of -195.8°C. Use liquid nitrogen This allows the waste material to be cooled to approximately -12°C (1'C). The material is discharged from the screw press at a temperature of approximately 50°C.

本発明に従う方法のもう１つの実施態様によれば、例えばそのゴム部分が既に砕 けやすくなっているような古ゴムの処理の場合のように、あまり低い温度を必要 としない場合にはその廃棄物に冷却のために冷水を添加混合する。According to another embodiment of the method according to the invention, for example the rubber part is already crushed. In some cases, such as in the case of processing old rubber that is easily peeled, temperatures that are too low are required. If not, add cold water to the waste for cooling.

冷却媒体は廃棄物をスクリュープレス中に装入するに先立ってその廃棄物と混合 することができ、その際それら廃棄物の個々の片と冷却媒体との緊密な混合に際 してその廃棄物片の最適の冷却がもたらされる。The cooling medium is mixed with the waste material prior to charging it into the screw press. The individual pieces of waste can then be intimately mixed with the cooling medium. This provides optimum cooling of the waste piece.

この特別な冷却によって廃棄物のスクリュープレス中での圧壊に際しても加硫や 後加硫を防止することができる。This special cooling prevents vulcanization from occurring when the waste is crushed in the screw press. Post-vulcanization can be prevented.

スクリュープレス中で圧壊する際に液体窒素や水のような冷却媒体の１部は既に このスクリュープレスの中で蒸発する。残余の液体はスクリュープレスから排出 された後でそれらの固体片から分離される。During crushing in the screw press, some of the cooling medium, such as liquid nitrogen or water, is already It evaporates in this screw press. Drain the remaining liquid from the screw press separated from the solid pieces.

固体廃棄物は好ましくはスクリュープレスの中へ装入するに先立って予備的に細 分割され、その際そのゴム含有廃棄物は例えば粒状化された形でそのスクリュー プレスの中へ送り込まれる。これによりその廃棄物をスクリュープレス中により 容易に導入することができるばかりでなく、更にその上にそれら細分割された多 片をより容易かつ迅速に冷却することができる。スクリュープレスから排出され る各構成成分もより容易に互いに分離することができる０例えば古タイヤのよう なゴム含有廃棄物からなる粒状化物は１０ＩＩＩＩｌ　ないし４０■　の直径を 有することができる。これによって各種金属質構成成分も更に小さな形で存在し 、従ってそれらは磁石を用い、又は篩分によって他の構成成分とより容易に分離 することができる。The solid waste is preferably pre-shredded before being charged into the screw press. The rubber-containing waste is then separated, for example in granulated form, into the screw. It is sent into the press. This allows the waste to be transferred into the screw press. Not only can they be easily introduced, but they can also be further subdivided into multiple Pieces can be cooled more easily and quickly. discharged from the screw press Each constituent component of the product can be more easily separated from the other. The granulated material consisting of rubber-containing waste has a diameter of 10III to 40 cm. can have As a result, various metallic components also exist in smaller forms. , therefore they are more easily separated from other constituents using magnets or by sieving. can do.

この廃棄物に印加される圧力はスクリュープレス内で１００　バールまでである ことができる。The pressure applied to this waste is up to 100 bar in the screw press. be able to.

この方法の特別な実施態様の１つによれば、個々の粒状化された砕片の間に存在 する、殆どの場合に比較的高い温度の外界空気はスクリュープレス中に送り込ま れる廃棄物から抜き出される。すなわちスクリュープレス中に空気が存在する場 合にはこのスクリュープレスの中の温度が過度に強く上昇し、そのためになお多 くの冷却媒体を添加混合しなければならなくなる。According to one particular embodiment of the method, between the individual granulated debris there is In most cases, relatively high temperature ambient air is fed into the screw press. extracted from waste. In other words, if air is present in the screw press, In this case, the temperature inside this screw press increases too strongly, so that even more Therefore, many cooling media must be added and mixed.

スクリュープレス内の大きな熱量によって水や液体窒素のような液体が蒸発する 。この蒸発した液体は有利には捕集して再び冷却するのがよい。The large amount of heat inside the screw press evaporates liquids such as water and liquid nitrogen. . This evaporated liquid is advantageously collected and cooled again.

好ましくはスクリュープレスの、例えばスクリュー外套管、スクリュー等のよう な各構成部材も冷却チャンネル中に送り込まれる液体窒素や冷水等によって冷却 し、それにより冷却が改善それるのみならず、冷却媒体も精製することなく再使 用することができるようになる。Preferably a screw press, such as a screw mantle, a screw, etc. Each component is also cooled by liquid nitrogen, cold water, etc. sent into the cooling channel. This not only improves cooling, but also allows reusing the cooling medium without purifying it. You will be able to use it.

スクリュープレスから排出される個々の廃棄物構成成分の混合物は次に篩分、磁 石による金属質成分の吸着除去等のような分離過程にかける。The mixture of individual waste components discharged from the screw press is then sieved, magnetically It is subjected to a separation process such as adsorption and removal of metallic components by stones.

スクリュープレスは例えば国際公開１ｆｏ−Ａ−８３１０３，９９９、ドイツ特 許公開Ｄε−へ−３，７１４，５０８、同ＤＥ−Ａ−３，７１４，５０９及び同 ＤＥ−Ａ−３，７１４，５１８に記述されているようなデザインを有することが できる。この場合には互いに平行に設けられた２本のスクリューを備えたスクリ ュープレスを対象とする。けれどもまた他の種々のスクリュープレスも用いるこ とができる。For example, the screw press is disclosed in International Publication 1fo-A-83103,999, German Special Edition. Publications DE-A-3,714,508, DE-A-3,714,509 and It may have a design as described in DE-A-3,714,518. can. In this case, a screwdriver with two screws parallel to each other is used. Targeted at Upress. However, various other screw presses can also be used. I can do it.

要約書 処理されるべき廃棄物の冷却によって、この廃棄物の各構成成分の砕けやすさを 利用してゴム含有廃棄物を再加工のために処理する方法が記述される力５、この 方法はそのゴム含有廃棄物を、スクリュープレス中で圧壊し、少なくともこのス クリュープレスの中で冷却し、そして場合によりこのスクリュープレスの中への 装入に先立って予め細分割することを特徴とする。この場合にその廃棄物しこ冷 却のために液体窒素又は水を添加混合する。この方法はエネルギー消費量を節約 することができ、そして窒素等の冷却媒体の必要量が少ない。abstract Cooling of the waste to be treated reduces the friability of each component of this waste. A method is described for processing rubber-containing waste for reprocessing using this force 5. The method involves crushing the rubber-containing waste in a screw press and at least cooling in the screw press and optionally into this screw press. It is characterized by being finely divided in advance before charging. In this case, the waste should be cooled down Add and mix liquid nitrogen or water for cooling. This method saves energy consumption and requires less cooling medium such as nitrogen.
