Description

Die Erfindung betrifft eine Vorrichtung zur Grobscheidung von Bauschutt nach dem Schwimm/Sinkverfahren, wobei ein Wassertank zur Aufnahme des Bauschutts, eine Austrageinrichtung für absinkendes Material in Form eines Kratzbands und eine Austrageinrichtung für aufschwimmendes Material vorgesehen sind.The invention relates to a device for coarse separation of building rubble using the floating / sinking method, a water tank for holding the building rubble, a discharge device for sinking material in the form of a scraper belt and a discharge device for floating material being provided.

Eine Vorrichtung dieses Typs ist bereits bekannt; sie setzt das Vorhandensein eines auf Korngrößen von 8 - 10 mm gebrochenen Bauschutts voraus. Der gebrochene Bauschutt wird dabei über einen zweigeteilten Abwurfkanal auf den ebenen Boden eines Wassertanks und dann von zwischen zwei seitlichen Antriebsketten gehaltenen Kratzbalken am Boden weitergefördert. Dabei schwimmt das Material mit einer Dichte <1 beim Abwurf des Materials in den Tank bzw. während des Schwermaterialtransports durch den Tank hindurch ohne weiteres auf. Auch das Schwermaterial wird letztlich wieder über Wasser gefördert und dort abgenommen.A device of this type is already known; it presupposes the presence of building rubble broken down to grain sizes of 8-10 mm. The broken building rubble is conveyed further via a two-part discharge channel onto the level floor of a water tank and then on the floor by means of scratching bars held between two side drive chains. The material with a density of <1 floats without difficulty when the material is dropped into the tank or during the transport of heavy material through the tank. The heavy material is ultimately also conveyed over water and removed there.

Auf der anderen Seite sind auch kontinuierliche Siebverfahren bekannt geworden, bei denen eine Siebklassierung von körnigen Schwermaterialien vollständig unter Wasser stattfindet. Derartige Siebvorrichtungen werden hauptsächlich im Bergbau eingesetzt und als hydraulische Setzmaschinen bezeichnet. Diese Anlagen arbeiten meist so, daß Siebe unterhalb der Wasseroberfläche gerüttelt werden. Vorrichtungen dieser Art sind in der US-A 4 563 271, der GB-A 2 173 130 und der GB-A 2 232 616 beschrieben. Davon betreffen die US-A 4 563 271 und die GB-A 2 173 130 Kaskadensetzmaschinen mit im rechten Winkel zur Wasseroberfläche hin und her bewegten ebenen Sieben und die GB-A 2 232 616 eine Setzmaschine mit einem Bogensieb. Mit dem Anmeldungsgegenstand haben derartige Vorrichtungen nichts gemeinsam.On the other hand, continuous screening processes have also become known, in which screening of granular heavy materials takes place completely under water. Screening devices of this type are mainly used in mining and are referred to as hydraulic setting machines. These systems usually work in such a way that sieves are shaken below the water surface. Devices of this type are described in US-A 4 563 271, GB-A 2 173 130 and GB-A 2 232 616. Of these, US-A 4 563 271 and GB-A 2 173 130 cascade typesetting machines with plane sieves moving back and forth at right angles to the water surface and GB-A 2 232 616 relate to a typesetting machine with a curved screen. Such devices have nothing in common with the subject of the application.

Demgegenüber besteht der Bedarf nach einer Grobscheidevorrichtung der eingangs genannten Art, mit der an der Abbruchstelle anfallender Bauschutt wie er ist verarbeitet werden kann - natürlich nach händischem Abtrennen von sperrigen Teilen wie Balken oder Trame, die als solche fast immer wiederverwendbar sind.In contrast, there is a need for a coarse separation device of the type mentioned at the outset, with which construction waste arising at the demolition site can be processed as it is - naturally after manual removal of bulky parts such as beams or trams, which as such are almost always reusable.

Zur Lösung dieser Aufgabe ist die erfindungsgemäße Vorrichtung vor allem dadurch gekennzeichnet, daß am Wassertank an einer Schmalseite eine Aufgaberutsche für Bauschutt, ein der Aufgaberutsche benachbartes, in Förderrichtung des absinkenden Materials zuerst absteigend und dann aufsteigend geführtes zentrales Kratzband sowie ein quer zur Längsachse des Wassertanks laufendes Abnahmeband für aufschwimmendes Material vorgesehen sind, dessen Abnehmleisten den Wasserspiegel im Wassertank vorzugsweise zumindest berühren.To achieve this object, the device according to the invention is characterized in particular in that on the narrow side of the water tank there is a feed chute for building rubble, one adjacent to the feed chute, descending and then ascending in the conveying direction of the sinking material, and a central scraper belt running as well as a crosswise to the longitudinal axis of the water tank Removal tape are provided for floating material, the removal strips preferably at least touch the water level in the water tank.

Vorteilhaft ist in diesem Zusammenhang, daß eine etwa in Höhe des Wasserspiegels im Wassertank angeordnete, mit Förderleisten versehene Förderwalze für aufschwimmendes Gut dem Abnahmeband in Förderrichtung des absinkenden Materials vorgeschaltet ist.In this context, it is advantageous that a conveyor roller for floating material, which is arranged approximately at the level of the water in the water tank and is provided with conveying strips, is connected upstream of the removal belt in the conveying direction of the sinking material.

Da die durch Schwimm/Sinkscheidung voneinander getrennten Komponenten des Bauschutts in tropfnassem Zustand ausgetragen werden, ist es nötig, laufend Wasser zur Konstanthaltung des Wasserspiegels im Wassertank zuzuführen.Since the components of the rubble separated by floating / sinking are discharged in a dripping wet state, it is necessary to continuously supply water to keep the water level in the water tank constant.

Dazu ist erfindungsgemäß vorgesehen, daß im Bereich der Aufgaberutsche eine Wassersprüh- bzw. -spritzeinrichtung zum Vorbefeuchten des Bauschutts und zur Konstanthaltung des Wasserspiegels im Wassertank vorgesehen ist.For this purpose, it is provided according to the invention that a water spray or spray device is provided in the area of the feed chute for pre-moistening the rubble and for keeping the water level in the water tank constant.

Die Erfindung wird nachstehend anhand eines Ausführungsbeispiels unter Bezugnahme auf die schematische Zeichnung näher beschrieben, in der Fig. 1 eine Seitenansicht, Fig. 2 eine Draufsicht und Fig. 3 eine Querschnittsansicht einer erfindungsgemäßen Grobscheidvorrichtung für Bauschutt zeigt.The invention is described in more detail below on the basis of an exemplary embodiment with reference to the schematic drawing, in which FIG. 1 shows a side view, FIG. 2 shows a plan view and FIG. 3 shows a cross-sectional view of a rough separating device according to the invention for building rubble.

Die dargestellte Vorrichtung ist als Sattelaufliegerfahrzeug 1 ausgebildet, das eine hintere Doppelachse 2 und vordere Absenkstützen 3 aufweist. Die für den Betrieb nötigen weiteren Absenkstutzen sind nicht dargestellt.The device shown is designed as a semi-trailer vehicle 1, which has a rear double axle 2 and front lowering supports 3. The additional lowering sockets required for operation are not shown.

Im Aufgabebereich für den Bauschutt ist ein offener Förderkanal 4 mit Umlauförderband 5 vorgesehen. Darunter befindet sich der Antriebsaggregatraum 6, in dem u.a. ein mit einer Verbrennungskraftmaschine 7 gekoppelter Stromgenerator 8 vorgesehen ist, der die Antriebsenergie für die einzelnen Fördereinrichtungen der Vorrichtung liefert.An open conveyor channel 4 with a circulating conveyor belt 5 is provided in the feed area for the building rubble. Underneath is the drive unit space 6, in which, among other things, a current generator 8 is provided which is coupled to an internal combustion engine 7 and which supplies the drive energy for the individual conveying devices of the device.

Der Bauschutt wird vom Förderband 5 auf eine rampenförmige Aufgaberutsche 9 abgeworfen, die so angeordnet ist, daß der Bauschutt nicht direkt auf die Stirnumlenkung 10 eines Kratzbands 11 fällt, das zentral entlang des Bodens eines Wassertanks 12 geführt ist, der keilförmig geneigte Wände (siehe z.B. Fig. 3) aufweist und dessen Boden so gewinkelt ist, daß er etwa nach dem in Förderrichtung des Bauschutts ersten Drittel der Länge des Wassertanks 12 eine tiefste Stelle 13 aufweist.The rubble is dropped from the conveyor belt 5 onto a ramp-shaped feed chute 9, which is arranged so that the rubble does not fall directly onto the front deflection 10 of a scraper belt 11, which is guided centrally along the bottom of a water tank 12, the wedge-shaped inclined walls (see e.g. Fig. 3) and the bottom of which is angled so that it has a deepest point 13 approximately after the first third of the length of the water tank 12 in the conveying direction of the rubble.

Im Abwurfbereich des Förderbands 5 ist eine Wassersprüh- bzw. -spritzeinrichtung 14 vorgesehen, die den abgeworfenen Bauschutt zur Staubbindung befeuchtet sowie den Wasserspiegel 15 im Wassertank 12 konstanthält.In the discharge area of the conveyor belt 5, a water spray or spray device 14 is provided, which moistens the thrown building rubble to bind dust and keeps the water level 15 in the water tank 12 constant.

Das Kratzband 11 fördert die Schwerkomponenten des Bauschutts in Pfeilrichtung 16 und wirft die nassen Schwerkomponenten am Heck des Sattelaufliegerfahrzeugs 1 ab.The scraper belt 11 conveys the heavy components of the rubble in the direction of the arrow 16 and throws off the wet heavy components at the rear of the semi-trailer vehicle 1.

Die unmittelbar nach dem Abwurf des Bauschutts im Wassertank 12 aufschwimmenden Leichtkomponenten werden von den Förderleisten 18 einer Förderwalze 17 erfaßt, unter Wasser gedrückt und zur Unterseite eines Abnahmebands 19 gefördert, das quer zur Längsachse des Sattelaufliegerfahrzeugs 1 läuft und dessen Abnehmleisten 20 das aufschwimmende Material seitlich aus dem Wassertank 12 hinausfördern, zu welchem Zweck eine seitliche Abgaberutsche am Wassertank 12 angeordnet werden kann.The light components floating immediately after the rubble is dropped in the water tank 12 are gripped by the conveyor bars 18 of a conveyor roller 17, pressed under water and conveyed to the underside of a take-off belt 19 which runs transversely to the longitudinal axis of the semi-trailer vehicle 1 and whose removal bars 20 laterally remove the floating material Convey the water tank 12 for what purpose a side discharge chute can be arranged on the water tank 12.

Vorzugsweise ist das Abnahmeband 19 so angeordnet, daß dessen Abnehmleisten 20 den Wasserspiegel 15 zumindest berühren.The take-off belt 19 is preferably arranged such that its removal strips 20 at least touch the water level 15.

Die Förderwalze 17 kann gegebenenfalls weggelassen werden, da beim Abwurf des Bauschutts aufschwimmendes Material infolge der kontinuierlichen Bauschuttzufuhr vom Abwurfbereich wegschwimmt.The conveyor roller 17 can optionally be omitted, since floating material when the rubble is discharged floats away from the discharge area due to the continuous supply of rubble.
