Abstract

It is known that children's sandpits are badly fouled by children and domestic animals. To clean the sand present in the sandpits, the invention proposes that a mobile system (1) sucks up the sand from the sandpit via a suction hose (2) by means of a vacuum, then feeds it to a washing silo (6) in which there is a washing liquid (5), which at the same time preferably takes the form of a heavy liquid, under the silo (6), by means of a separating member (8) coupled to a discharging member (7), the sand is discharged and the washing liquid returned, and then the sand is fed to the storage silo (9) pneumatically and/or by belt conveyor and from here is returned to the sandpit pneumatically and/or by belt conveyor. <IMAGE>

Description

Arbeitsweise der erfindungsgemäßen Vorrichtung:Operation of the device according to the invention:

Der Sand aus dem Spielkasten wird über einen Saugschlauch (2) aufgesaugt, über einen Zyklon (3) abgeschieden und dann einer spezifischen Waschflüssigkeit (5) im Waschsilo (6) zugeteilt, in der der Sand nach unten absackt und die verunreinigten Stoffe über eine Flüssigkeit nach oben aufsteigen.The sand from the play box is sucked up via a suction hose ( 2 ), separated by a cyclone ( 3 ) and then allocated to a specific washing liquid ( 5 ) in the washing silo ( 6 ), in which the sand sinks down and the contaminated substances via a liquid ascend to the top.

Zur Intensivierung der Waschung wird Luft über Düsen in den Waschsilo 6 eingeleitet (11), wobei diese Luft vorzugsweise vom Unterdruckerzeuger (4) druckseitig abgenommen wird.To intensify the washing, air is introduced into the washing silo 6 via nozzles ( 11 ), this air preferably being taken off on the pressure side by the vacuum generator ( 4 ).

Im oberen Bereich des Waschsilos werden die verunreinigten Stoffe entfernt (12), und der Sand wird unten am Waschsilo (6) über ein Austragsorgan (7) einem Wassertrennsieb (8) übergeben, danach über eine pneumatische Förderung oder ein Becherwerk in den Vorratssilo (9) gefördert und anschließend mittels pneumatischer Förderung oder Band (10) wieder in den Sandkasten zurückgeführt.In the upper area of the washing silo, the contaminated substances are removed ( 12 ), and the sand is transferred to the bottom of the washing silo ( 6 ) via a discharge device ( 7 ) to a water separating sieve ( 8 ), then via pneumatic conveying or a bucket elevator into the storage silo ( 9 ) conveyed and then returned to the sandpit by means of pneumatic conveying or belt ( 10 ).

Hierdurch ist die Gewähr gegeben, daß z. B. ein Fahrzeug das fahrbare Gerät (1) zum Einsatzort bringen kann, und hier kann - angetrieben über einen Dieselmotor - z. B. das Drehkolbengebläse bzw. die Wasserringpumpe - als Unterdruckerzeuger (4) ausgebildet - den notwendigen Sog erzeugen, um den Sand in den Waschsilo zu bringen und anschließend über eine pneumatische Förderung (10) wieder zurückzuführen.This ensures that z. B. a vehicle can bring the mobile device ( 1 ) to the site, and here - driven by a diesel engine - z. B. the rotary lobe blower or the water ring pump - designed as a vacuum generator ( 4 ) - generate the necessary suction to bring the sand into the washing silo and then return via a pneumatic conveyor ( 10 ).

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellten Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, Sandkästen zur Reinigung des Sandes so zu behandeln, daß sie saugseitig abgesaugt werden und der zu reinigende Sand einem Waschsilo zugeführt wird, in dem eine Reinigungsflüssigkeit in Form von z. B. biologisch abbaubarer Schwertrübeflüssigkeit eingelagert ist, die den schweren Sand gewaschen nach unten absinken läßt, wobei die verunreinigten Stoffe ausgewaschen bzw. nach oben aufgeschlämmt werden.Of course, the invention is not based on the forms of training described above in detail limited, but there are numerous Changes possible, but without the Deviate basic ideas, sandboxes for cleaning to treat the sand so that it is sucked off on the suction side and the sand to be cleaned in a washing silo is supplied in which a cleaning liquid in the form of e.g. B. biodegradable heavy cloud liquid which is the heavy sand washed down can sink, the contaminated Washed out fabrics or slurried upwards will.
