Description

Die vorliegende Erfindung betrifft eine Vorrichtung zur Aufbereitung von Mineralwolleabfällen, insbesondere von Glas- oder Steinwolleabfällen, umfassend mindestens eine Pressvorrichtung zur Aufnahme und Verpressen von verpackten und/oder unverpackten Mineralwollegebinden.The present invention relates to a device for the treatment of mineral wool waste, in particular glass or rock wool waste, comprising at least one pressing device for receiving and pressing of packaged and / or unpacked mineral wool bundles.

Mineralwolleprodukte werden insbesondere als Dämmstoffe in der Bauindustrie verwendet. Dabei kommen diese insbesondere in Form von Glaswolle oder Steinwolle zum Einsatz. Typische Mineralwolle-Dämmstoffe enthalten üblicherweise mindestens 90 % künstliche Mineralfasern glasiger Struktur, bis zu 7 % Kunstharz, ca. 1 % Öle und weitere Zusatzstoffe. Bei der Verarbeitung von Mineralwolle sowie insbesondere bei der Sanierung von Bauten fallen nicht unerhebliche Mengen an Mineralwolleabfällen an. Dabei werden diese Abfälle ins zwei Kategorien eingeteilt, nämlich so genannte "alte Mineralwolle" gemäß dem Abfallschlüssel 170603 und eine so genannte "neue Mineralwolle" gemäß dem Abfallschlüssel 170604. "Neue Mineralwolle" wird aufgrund der Beschaffenheit der Faserstruktur als frei von Krebsverdacht eingestuft. Bei "alter Mineralwolle" handelt es sich um besonders überwachungsbedürftige Abfälle, die nur von fachlich geeigneten Firmen ausgebaut und entsorgt werden dürfen. So sind diese Mineralwolleabfälle bereits am Entstehungsort staubdicht zu verpacken und gegebenenfalls zu befeuchten. Für den Transport sind geschlossene Behältnisse wie zum Beispiel reißfeste Kunststoffsäcke oder Gewebesäcke zu verwenden. Aufgrund potentieller Gesundheitsgefährdung darf alte Mineralwolle nicht mehr verwendet werden. Zudem dürfen derartige Mineralwolle-Dämmstoffe grundsätzlich nicht wieder eingebaut werden und müssen entsorgt werden. Zur Optimierung des Transports und des deponiebachtechnischen Einbaus von Mineralwolleabfällen ist es bekannt, verpackte Mineralwollegebinde zu verpressen.Mineral wool products are used in particular as insulating materials in the construction industry. These are used in particular in the form of glass wool or rock wool. Typical mineral wool insulation materials usually contain at least 90% synthetic mineral fibers of glassy structure, up to 7% synthetic resin, about 1% oils and other additives. In the processing of mineral wool and in particular in the renovation of buildings incur not inconsiderable amounts of mineral wool waste. The waste is divided into two categories, namely so-called "old mineral wool" according to waste code 170603 and a so-called "new mineral wool" according to waste code 170604. "New mineral wool" is classified as free of suspected cancer due to the nature of the fiber structure. "Old mineral wool" is a waste that requires special monitoring, which may only be removed and disposed of by suitably qualified companies. For example, these mineral wool wastes must be packed dust-tight at the point of origin and, if necessary, moistened. For transport, closed containers such as tear-resistant plastic bags or fabric sacks are to be used. Due to potential health hazards old mineral wool may no longer be used. In addition, such mineral wool insulating materials must not be reinstalled and must be disposed of. In order to optimize the transport and installation of mineral wool waste, it is known to crimp packaged mineral wool packages.

Nachteilig an den bisher bekannten Verfahren und Vorrichtungen ist jedoch, dass ein sicheres und umweltgerechtes Verpressen derartiger Mineralwollegebinde aufgrund der durch das Verpressen entstehenden Staubentwicklung und Faserfreisetzung nicht oder nur unzureichend möglich ist.A disadvantage of the previously known methods and devices, however, is that a safe and environmentally sound compression of such mineral wool bundles due to the resulting dust by the compression and fiber release is not or only insufficiently possible.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Vorrichtung zur Aufbereitung von Mineralwolleabfällen, insbesondere von Glas- oder Steinwolleabfällen, der eingangs genannten Art bereitzustellen, die eine sicheres Verpressen von verpackten und/oder unverpackten Mineralwollegebinden gewährleistet.It is therefore an object of the present invention to provide a device for the treatment of mineral wool wastes, in particular of glass or rock wool waste, of the type mentioned, which ensures a safe pressing of packaged and / or unpackaged mineral wool bundles.

Zur Lösung dieser Aufgabe dient eine gattungsgemäße Vorrichtung gemäß den Merkmalen des Anspruchs 1.To solve this problem is a generic device according to the features of claim 1.

Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.Advantageous embodiments are described in the subclaims.

Eine erfindungsgemäße Vorrichtung zur Aufbereitung von Mineralwolleabfällen, insbesondere von Glas- oder Steinwolleabfällen, umfasst mindestens eine Pressvorrichtung zur Aufnahme und Verpressen von verpackten und/oder unverpackten Mineralwollegebinden sowie mindestens eine Absaugvorrichtung, wobei die Absaugvorrichtung bezüglich der Pressvorrichtung derart angeordnet ist, dass aus der Pressvorrichtung während des Verpressens austretende Stäube und/oder Mineralfasern von der Absaugvorrichtung angesaugt und mindestens einer mit der Absaugvorrichtung verbundenen oder in der Absaugvorrichtung integrierten Filtervorrichtung zuführbar sind. Die erfindungsgemäße Vorrichtung gewährleistet ein sicheres Verpressen von verpackten und/oder unverpackten Mineralwollegebinden. Insbesondere sind durch die Absaugvorrichtung und die Filtervorrichtung gewährleistet, dass der für die möglicherweise krebserzeugende beziehungsweise krebsverdächtige Mineralwolle-Dämmstoffe geltende Luftgrenzwert von 250000 Fasern/m3 eingehalten wird. Idealerweise wird dieser Luftgrenzwert deutlich unterschritten. Auch die Staubentwicklung wird durch die erfindungsgemäße Vorrichtung auf ein Minimum reduziert. Dadurch wird es möglich, verpackte und/oder unverpackte Mineralwollegebinde sicher zu verpressen, so dass es zu einer deutlichen Volumenreduzierung der entstehenden Abfallprodukte kommt. Dies führt zu einer Optimierung sowohl des Transportes wie auch des deponiebautechnischen Einbaus der Mineralwolleabfälle.A device according to the invention for the treatment of mineral wool waste, in particular of glass or rock wool waste, comprises at least one pressing device for receiving and compressing packed and / or unpacked mineral wool bundles and at least one suction device, wherein the suction device is arranged with respect to the pressing device such that from the pressing device during sucked by pressing dust and / or mineral fibers sucked by the suction device and at least one connected to the suction device or integrated in the suction filter device can be fed. The device according to the invention ensures a secure pressing of packaged and / or unpackaged mineral wool bundles. In particular, the suction device and the filter device ensure that the air limit value of 250,000 fibers / m 3 applicable to the possibly carcinogenic or suspected mineral wool insulation materials is complied with becomes. Ideally, this air limit is significantly below. The dust development is reduced by the device according to the invention to a minimum. This makes it possible to safely compress packed and / or unpackaged mineral wool packages, so that there is a significant reduction in volume of the resulting waste products. This leads to an optimization of both the transport and the landfill construction of mineral wool waste.

In weiteren vorteilhaften Ausgestaltungen der erfindungsgemäßen Vorrichtung umfasst die Absaugvorrichtung mindestens eine Absaughaube und/oder eine Absaugwand.

Zudem können die Filterelemente austauschbar und/oder reinigbar ausgebildet sein. Durch diese Maßnahmen ist ein sicheres Verpressen von verpackten und/oder unverpackten Mineralwollegebinden möglich. Des Weiteren können die genannten Einzelelemente der erfindungsgemäßen Vorrichtung den Anforderungen vor Ort angepasst werden. Auch die Absaugvorrichtung kann als separates Element der erfindungsgemäßen Vorrichtung ausgebildet sein. Dies hat den Vorteil, dass bereits vorhandene Pressvorrichtungen nachträglich mit der Absaugvorrichtung ausrüstbar sind.In further advantageous embodiments of the device according to the invention, the suction device comprises at least one suction hood and / or a suction wall. In addition, the suction hood and / or suction wall can be connected to the filter device via a suction line. The filter device may in turn comprise at least one filter element for retaining the mineral fibers and / or dusts. In addition, the filter elements can be exchangeable and / or cleanable. Through these measures, a secure pressing of packaged and / or unpacked mineral wool bundles is possible. Furthermore, the mentioned individual elements of the device according to the invention can be adapted to the requirements on site. Also, the suction device may be formed as a separate element of the device according to the invention. This has the advantage that already existing pressing devices can be retrofitted with the suction device.

In weiteren vorteilhaften Ausgestaltungen der erfindungsgemäßen Erfindung umfasst die Pressvorrichtung eine Ballen- oder Schrankpresse. Auch andere Arten von Pressen sind denkbar. Dabei kann die Pressvorrichtung mindestens eine Aufnahmeöffnung zur Aufnahme von mittels mindestens einer ersten Fördervorrichtung angelieferten Mineralwollegebinden und mindestens eine Ausgabeöffnung zur Ausgabe der gepressten Mineralwollegebinde. Zudem ist es möglich, dass die Ausgabeöffnung mit einer zweiten Fördervorrichtung zum Abtransport der gepressten Mineralwollegebinde in Wirkverbindung steht. Eine derartige Ausgestaltung und Anordnung der erfindungsgemäßen Vorrichtung gewährleistet die automatische Aufbereitung von Mineralwolleabfällen. Damit ist es möglich, ein hohes Volumen an Mineralwolleabfällen in kurzer Zeit zu verarbeiten.In further advantageous embodiments of the invention, the pressing device comprises a bale or cabinet press. Other types of presses are conceivable. In this case, the pressing device can have at least one receiving opening for receiving mineral wool bundles delivered by means of at least one first conveying device and at least one dispensing opening for dispensing the pressed mineral wool bundles. In addition, it is possible for the dispensing opening to be in operative connection with a second conveying device for removing the pressed mineral wool packages. Such a configuration and arrangement of the device according to the invention ensures the automatic treatment of mineral wool waste. This makes it possible to process a high volume of mineral wool waste in a short time.

In einer weiteren vorteilhaften Ausgestaltung der erfindungsgemäßen Vorrichtung ist diese transportabel ausgebildet. Damit ist es möglich, dass die Vorrichtung vor Ort, das heißt am Entstehungsort der Mineralwolleabfälle, positioniert werden kann, so dass mögliche Umwelt- oder Gesundheitsgefährdungen durch einen unsachgemäßen Transport der Mineralwolleabfälle von dem Entstehungsort zum Verwertungsort vermieden werden.In a further advantageous embodiment of the device according to the invention, this is designed to be transportable. Thus, it is possible that the device on-site, that is at the origin of the mineral wool waste, can be positioned so that possible environmental or health hazards are avoided by improper transport of mineral wool waste from the place of origin to the recovery.

Verwendung findet die im Vorhergehenden beschriebene erfindungsgemäße Vorrichtung bei der Aufbereitung von Mineralwolleabfällen, insbesondere von Glas-oder Steinwolleabfällen.

FIG. 2
a schematic representation of a device according to the invention for the treatment of mineral wool waste according to a second embodiment.

Figur 1 zeigt eine schematische Darstellung einer Vorrichtung 10 zur Aufbereitung von Mineralwolleabfällen gemäß einer ersten Ausführungsform. Die Vorrichtung 10 umfasst dabei eine Pressvorrichtung 12 zur Aufnahme und Verpressen von verpackten Mineralwollegebinden 34. Die schematisch dargestellte Pressvorrichtung 12 ist in dem genannten Ausführungsbeispiel eine so genannte Ballenpresse. Sie weist eine Aufnahmeöffnung 24 zum Einbringen der Mineralwollegebinde 34 auf. Mittels hydraulischer Zylinder werden innerhalb der Pressvorrichtung 12 die Mineralwollegebinde 34 verpresst und im verpressten Zustand wieder entnommen. Durch die Verpressung der Mineralwollegebinde 34 erfolgt eine deutliche Volumenreduzierung der üblicherweise in reißfeste Kunststoffsäcke verpackten Mineralwollegebinde 34. Zudem umfasst die Vorrichtung 10 eine Absaugvorrichtung 16, welche aus einer Absaughaube 14 und einer Filtervorrichtung 20 sowie einer die Abzugshaube 14 und die Filtervorrichtung 20 verbindenden Absaugleitung 18 besteht. Die Absaughaube 14 ist im dargestellten Ausführungsbeispiel über der Pressvorrichtung 12 angeordnet. Es ist aber auch möglich, die Absaughaube 14 seitlich an der Pressvorrichtung 12 zu positionieren. Zudem besteht die Möglichkeit eine so genannte Absaugwand im Bereich der Pressvorrichtung 12 zu installieren. Des Weiteren ist in dem dargestellten Ausführungsbeispiel ein Unterdruckhaltegerät in der Filtervorrichtung 20 integriert, wobei die Absaugung von Stäuben und/oder Mineralfasern, die während des Verpressens der Mineralwollegebinde 34 in der Pressvorrichtung 12 entstehen, mittels Unterdruck über die Absaughaube 14 abgesaugt werden. Beispielsweise kann die als Pressvorrichtung 12 verwendete Ballenpresse mit einer Presskraft von ca. 620 kN und einer Leistung von ca. 7,5 kW eingesetzt werden. Die Absaugung erfolgt mit dem genannten Unterdruckhaltegerät. Die Luftleistung beträgt dabei ca. 500 m3/h bei einer Leistung von ca. 0,3 kW. Die Absaughaube 14 kann auch als so genannte Drallhaube ausgebildet sein. Die Absaugvorrichtung 16 ist in den dargestellten Ausführungsbespielen als separate Einheit ausgebildet. Dies hat den Vorteil, dass bereits vorhandene Pressvorrichtungen nachträglich mit der Absaugvorrichtung 16 ausrüstbar sind. FIG. 1 shows a schematic representation of an apparatus 10 for the treatment of mineral wool waste according to a first embodiment. In this case, the device 10 comprises a pressing device 12 for receiving and pressing packaged mineral wool packages 34. The schematically illustrated pressing device 12 is a so-called baling press in the mentioned embodiment. It has a receiving opening 24 for introducing the mineral wool packages 34. By means of hydraulic cylinders, the mineral wool bundles 34 are pressed inside the pressing device 12 and removed again in the compressed state. By the compression the mineral wool package 34 is a significant reduction in volume of mineral wool packages usually packed in tear-resistant plastic bags 34. In addition, the device 10 comprises a suction device 16, which consists of a suction hood 14 and a filter device 20 and a suction line 18 connecting the hood 14 and the filter device 20. The suction hood 14 is arranged above the pressing device 12 in the illustrated embodiment. But it is also possible to position the suction hood 14 laterally on the pressing device 12. In addition, it is possible to install a so-called suction wall in the region of the pressing device 12. Furthermore, in the illustrated embodiment, a vacuum holding device is integrated in the filter device 20, wherein the suction of dusts and / or mineral fibers, which arise during the pressing of the mineral wool bundles 34 in the pressing device 12, are sucked by means of negative pressure on the suction hood 14. For example, the baler used as pressing device 12 can be used with a pressing force of about 620 kN and a power of about 7.5 kW. The extraction takes place with the mentioned vacuum holding device. The air output is about 500 m 3 / h at a power of about 0.3 kW. The suction hood 14 can also be designed as a so-called swirl hood. The suction device 16 is formed in the illustrated Ausführungsbespielen as a separate unit. This has the advantage that already existing pressing devices can be retrofitted with the suction device 16.

Des Weiteren erkennt man, dass die Filtervorrichtung 20 zwei Filterelemente 22 umfasst. Das Filtermaterial kann dabei der Anwendung angepasst werden, so dass die beim Verpressen der Mineralwollegebinde 34 entstehenden Stäube und/oder Mineralfasern nahezu vollständig in den Filterelementen 22 verbleiben. Die Filterelemente 22 können dabei austauschbar und/oder reinigbar ausgebildet sein. In dem dargestellten Ausführungsbeispiel erfolgt die Abreinigung der Filterelemente 22 im so genannten Offline-Modus mittels eines Rüttelmotors (nicht dargestellt). Die Stäube und/oder Mineralfasern werden in einem separaten Behälter aufgefangen. Insbesondere werden die Filterelemente 22 derart ausgewählt, dass die Luftwerte am Arbeitsplatz kleiner 50000 Fasern/m3 betragen. Des Weiteren ist es möglich, eine zusätzliche Absaugeinheit an der Filtervorrichtung 20 anzuschließen (nicht dargestellt).Furthermore, it can be seen that the filter device 20 comprises two filter elements 22. The filter material can be adapted to the application, so that the dusts and / or mineral fibers resulting from the pressing of the mineral wool bundles 34 remain almost completely in the filter elements 22. The filter elements 22 may be formed exchangeable and / or cleanable. In the illustrated embodiment, the cleaning of the filter elements 22 takes place in the so-called offline mode by means of a vibrator motor (not shown). The dusts and / or mineral fibers are collected in a separate container. In particular, the filter elements 22 are selected such that the air values at the workplace are less than 50,000 fibers / m 3 . Furthermore, it is possible to connect an additional suction unit to the filter device 20 (not shown).

Die Aufbereitung von Mineralwolleabfällen mittels der Vorrichtung 10 wird wie folgt ausgeführt:

  • Zunächst werden die verpackten Mineralwollegebinde 34 in die Pressvorrichtung 12 gegeben. Gegebenenfalls werden die Mineralwollegebinde 34 zusätzlich befeuchtet.
  • Danach erfolgt das Verpressen der einzelnen Mineralwollegebinde 34 zu Ballen 36 (vergleiche auch Figur 2). Die verpressten Ballen 36 können anschließend zu einer Deponie transportiert und entsprechend entsorgt beziehungsweise gelagert werden.
  • Nach jedem Arbeitsgang wird die Pressvorrichtung 12 mit einem zusätzlichen Sauger gereinigt.
The treatment of mineral wool waste by means of the device 10 is carried out as follows:
  • First, the packed mineral wool packages 34 are placed in the pressing device 12. Optionally, the mineral wool bundles 34 are additionally moistened.
  • Thereafter, the pressing of the individual mineral wool package 34 to bale 36 (see also FIG. 2 ). The compressed bales 36 can then be transported to a landfill and disposed of or stored accordingly.
  • After each operation, the pressing device 12 is cleaned with an additional sucker.

In dem dargestellten Ausführungsbeispiel folgt der so genannte Rohgaseintritt oben an der Filtervorrichtung 20. Es ist aber auch möglich, dass der Rohgaseintritt am unteren, bodenseitigen Ende der Filtervorrichtung 20 erfolgt. Dadurch kann eine Schwerkraft-Vorabscheidung der Stäube und Mineralfasern erfolgen. In diesem Fall kann das Reingas oben zentrisch oder seitlich aus der Filtervorrichtung 20 austreten.In the illustrated embodiment, the so-called raw gas inlet follows at the top of the filter device 20. However, it is also possible for the raw gas inlet to take place at the lower, bottom-side end of the filter device 20. This allows a gravity pre-separation of dusts and mineral fibers done. In this case, the clean gas at the top centric or laterally emerge from the filter device 20.

Figur 2 zeigt eine schematische Darstellung einer Vorrichtung 10 zur Aufbereitung von Mineralwolleabfällen gemäß einer zweiten Ausführungsform. Im Unterschied zu der in Figur 1 dargestellten ersten Ausführungsform erfolgt hier die Zuführung der Mineralwollegebinde 34 zu der Pressvorrichtung 12 über eine erste Fördervorrichtung 26. Die Pressvorrichtung 12 weist hierzu eine Aufnahmeöffnung 30 zur Aufnahme der angelieferten Mineralwollegebinde 34 auf. Nach dem Verpressen der Mineralwollegebinde 34 innerhalb der Pressvorrichtung 12 erfolgt ein automatischer Abtransport der gepressten Ballen 36 über eine Ausgabeöffnung 32 der Pressvorrichtung 12 und eine zweite Fördervorrichtung 28. Die Ausgestaltung der Absaugvorrichtung 16 entspricht der im ersten Ausführungsbeispiel der Vorrichtung 10 beschriebenen.
