Abstract

Description

Die Erfindung betrifft eine Mischvorrichtung, insbesondere für bituminöse Mischungen, Mischungen, welche mit dieser Mischvorrichtung hergestellt sind sowie Baukonstruktionen, insbesondere Wasserbaukonstruktionen, welche mit diesen Mischungen ausgeführt sind.The invention relates to a mixing device, in particular for bituminous mixtures, mixtures which are produced with this mixing device and building structures, in particular hydraulic structures which are made with these mixtures.

Bei der Herstellung von bituminösen Mischungen zur Verwendung im Strassenbau oder im Wasserbau wird meistens Gebrauch gemacht von Asphalt-Mischvorrichtungen, welche hauptsächlich eine Trockentrommel mit Entstaubung, eine Dosiervorrichtung für die verschiedenen Mineralien und Bitumen sowie eine Mischvorrichtung für die Bereitung der Mischung enthalten.In the production of bituminous mixtures for use in road construction or hydraulic engineering, use is usually made of asphalt mixing devices, which mainly contain a drying drum with dedusting, a metering device for the various minerals and bitumen, and a mixing device for preparing the mixture.

Meistens sind diese Mischvorrichtungen ausserdem noch mit den erforderlichen Speichervorrichtungen für die Lagerung von Mineralien, Bitumen und des fertigen Produktes versehen.Most of these mixing devices are also provided with the necessary storage devices for the storage of minerals, bitumen and the finished product.

In der Trockentrommel werden die Mineralien getrocknet und auf die gewünschte Temperatur erhitzt. In dem meisten Fällen muss das Mineral auf ca. 2500C erwärmt- werden. Als Wärmequelle wird in der Trockentrommel von einem Brenner Gebrauch gemacht, welcher mit Gas oder Gasöl beheizt wird. Zur Verbrennung müssen grosse Mengen von Luft zugeführt werden.The minerals are dried in the drying drum and heated to the desired temperature. In most cases, the mineral must be erwärmt- to approximately 250 0 C. A burner, which is heated with gas or gas oil, is used as a heat source in the drying drum. Large amounts of air must be added for combustion.

Die Brenngase werden abgesaugt und müssen gefiltert werden, damit der abgesaugte Staub ausgefiltert wird. In letzten Jahrzehnten sind aus Umweltgründen die Auflagen für diese Entstaubung immer strenger geworden. Die meisten Anlagen sind daher mit sogenannten Tuchfiltern oder nassen Filtersystemen zum Ausfiltern des Staubes versehen.The fuel gases are extracted and must be filtered so that the extracted dust is filtered out. For environmental reasons, the requirements for this dedusting have become increasingly strict in recent decades. Most systems are therefore equipped with so-called cloth filters or wet filter systems to filter out the dust.

Neben diesen bekannten Mischanlagen, die schubweise arbeiten, sind auch die sogenannten Trommelmischer bekannt, die aus einer rotierenden Trommel bestehen. In dieser Trommel wird sowohl das Mineral erwärmt und getrocknet,wie auch das Mineral und das Bitumen vermischt. Auch dieser Typ von Mischvorrichtungen ist mit einer Absaugung und Entstaubung versehen. Ein Nachteil der Trommelmischer besteht darin, dass überfüllte Mischungen nicht oder nur mit gewissen Begrenzungen hergestellt werden können.In addition to these known mixing plants, which operate in batches, so-called drum mixers are also known, which consist of a rotating drum. In that drum the mineral is heated and dried, and the mineral and bitumen are mixed. This type of mixing device is also provided with suction and dust removal. A disadvantage of the drum mixer is that overfilled mixtures cannot be produced or can only be produced with certain limitations.

Für beide beschriebene Mischvorrichtungen gilt, dass die Notwendigkeit des Gebrauches einer Absaugung und Entstaubung zu einem hohen Energieverbrauch führt, da ein grosser Teil der Wärme abgesaugt wird. Ausserdem ist für den Antrieb der Entstaubung ein durch einen Diesel- oder Elektromotor angetriebener Ventilator nötig.For both of the mixing devices described, the need to use suction and dust removal leads to high energy consumption since a large part of the heat is extracted. In addition, a fan driven by a diesel or electric motor is required to drive the dedusting.

Der Zusatz von altem Asphalt ist mit einigen Begrenzungen .in beiden Typen dieser bekannten Anlagen möglich. Die Begrenzungen betreffen den Anteil des Zusatzes, d.h., dass nur ein Teil des neu zubereiteten Asphaltes aus altem Asphalt bestehen kann. Beim schubweise arbeitenden Typ kann der Zusatz bis 25% betragen. Beim Trommelmischer liegt dieses Verhältnis bei ca. 50%.The addition of old asphalt is possible with some limitations in both types of these known plants. The limits concern the proportion of the additive, i.e. that only part of the newly prepared asphalt can consist of old asphalt. In the case of batch type, the addition can be up to 25%. With the drum mixer, this ratio is approx. 50%.

Die Erfindung betrifft eine Mischvorrichtung, die keine Absaugung oder Entstaubung erfordert,und bei welcher eine vollständige Verwendung von altem Asphalt möglich ist. Versuche haben erwiesen, dass der Energieverbrauch wesentlich günstiger ist als bei den bekannten Mischvorrichtungen.The invention relates to a mixing device which does not require suction or dust removal and in which a complete use of old asphalt is possible. Tests have shown that the energy consumption is considerably cheaper than in the known mixing devices.

Die Mischvorrichtung nach der Erfindung ist mit einem mit einem Medium beheizten Rotor versehen, welcher konzentrisch innerhalb eines Aussenmantels drehbar ist, der sich in geringem Abstand vom Rotor befindet,und der ebenfalls durch ein Medium beheizt wird, wobei sich das zu mischende Material im spaltförmigen Zwischenraum zwischen Rotor und dem Aussenmantel befindet.The mixing device according to the invention is provided with a medium heated rotor, which can be rotated concentrically within an outer casing, which is located at a short distance from the rotor, and which is also heated by a medium, the material to be mixed being in the gap-shaped space between the rotor and the outer jacket.

Die Erfindung betrifft auch ein Verfahren zur Bereitung von Mischungen, insbesondere bituminösen Mischungen,wohl oder nicht unter Mitverwendung von altem Asphalt und .wohl oder nicht mit Zufügungen wie z.B. Gummi oder Kunststoffen wobei die Mischvorrichtung .angewandt .wird sowie Mischungen, die nach dem Verfahren hergestellt werden und Baukonstruktionen, insbesondere Wasserbaukonstruktionen, welche mit diesen Mischungen hergestellt werden.The invention also relates to a process for the preparation of mixtures, in particular bituminous mixtures, whether or not using old asphalt and whether or not with additions such as e.g. Rubber or plastics, the mixing device being used, and mixtures which are produced by the method and building structures, in particular hydraulic structures which are produced using these mixtures.

Füllstoffe und gemahlener Gummi von alten Autoreifen werden dosiert in eine Zuführöffnung an einer Seite der Vorrichtung eingeführt,und die gebildete Mischung wird aus einer Abführöffnung abgeführt, die sich vorzugsweise an der anderen Seite der Vorrichtung befindet.The ingredients for these mixtures, e.g. Bitumen, minerals, broken old asphalt, natural or synthetic rubber, plastics, aggregates such as Fillers and ground rubber from old car tires are metered into a feed opening on one side of the device, and the mixture formed is discharged from a discharge opening, which is preferably on the other side of the device.

Der Rotor ist vorzugsweise ein Zylinder, der an der Aussenseite mit Vorsprüngen, wie z.B. Nocken Stiften und/oder Rippen zum Transport und/oder der Mischung des zu mischenden Materiales versehen ist.The rotor is preferably a cylinder which is provided on the outside with projections, e.g. Cam pins and / or ribs for transport and / or the mixing of the material to be mixed is provided.

Im Aussenmantel befinden sich vorzugsweise eine oder mehrere Oeffnungen zur Ableitung von Gasen, wie Z.B. Wasserdampf. Der Aussenmantel kann doppelwandig ausgebildet sein und ist vorzugsweise demontierbar, z.B. durch ein Scharnier in der Längsrichtung aufklappbar.In the outer jacket there are preferably one or more openings for discharging gases, such as e.g. Steam. The outer jacket can be double-walled and is preferably removable, e.g. hinged in the longitudinal direction.
