Description

Beschreibung zum querdurchströmten Absetzbecken mit beweglichen Zwischenböden und einem Einlauf mit Coanda - Effekt.Description of the cross-flow sedimentation basin with movable intermediate floors and an enema with a Coanda effect.

Die nachstehend näher beschriebene Erfindung kann überall dort eingesetzt werden, wo absetzbare Stoffe aus dem Wasser zu entfernen sind.The invention described in more detail below can be used anywhere where sediments are to be removed from the water.

Die Größe des für Absetzzwecke zur Verfügung zu stellenden Raumes hängt sehr wesentlich von der oberflächenbelastung des Reinigungssystems ab.The size of the space to be made available for settling purposes depends very much on the surface load of the cleaning system.

Bei dem Einbau von Zwischenböden wird eine erhebliche Verbesserung des Wirkungsgrades des Absetzvorganges erreicht. Diese Erkenntnis ist nicht neus läßt sich jedoch technisch nicht verwirklichen, wenn starre Zwischenböden eingebaut werden, da eine Reinigung der Zwischenböden nicht möglich erscheint Die Erfindung ist dadurch gekennzeichnet, daß als Zwischenböden Kunststofffolien verwand werden. Diese Zwischenböden sind beweglich ausgebildet und lassen sich ueber Rollen beugen, sodaß eine praktisch selbsttätige Reinigung erfolgt.The installation of intermediate floors is a significant improvement the efficiency of the settling process is achieved. This knowledge is not new However, this cannot be achieved technically if rigid intermediate floors are installed as a cleaning of the intermediate floors does not seem possible The invention is characterized in that plastic films are used as intermediate floors. These intermediate floors are designed to be movable and can be bent over rollers, so that a practically automatic cleaning takes place.

Patentansprüche beziehen sich auf 1. en Einlauf in das Becken (1). # Dieser Einlauf ist dadurch gekerinzeich net, daß der ß/ Coanda - Effekt ausgenutzt wird. Dieser Effekt hat die Eigenschaft, einen aus einem Schlitz oder einer Öffnung austretenden i2sserstrahl an in der Nähe befindliche Wände anzulehnen und umzulenken, Durch vorgenannten Effekt wird erreicht, daß das zuströmende Wasser in dem Einlaufbereich des Absetzbeckens gleichmäßig auf der ganzen Länge verteilt wird, mit einer deutlich ausgebildeten aufwärts gerichteten Strömung. Claims relate to 1. en inlet into the basin (1). # This enema is characterized by the fact that the ß / Coanda effect is used will. This effect has the property of having a slot or an opening to lean the emerging i2ss jet against nearby walls and deflect it, The aforementioned effect ensures that the inflowing water is in the inlet area of the sedimentation basin is evenly distributed along the entire length, with a clearly trained upward flow.

Durch den Einlauf im unteren Teil des Beckens wird eine bessere Durchmischung erreicht und Dichteströmungen durch Temperatureinflüsse können weitgehend vermieden werden. The enema in the lower part of the basin ensures better mixing achieved and density flows due to temperature influences can largely be avoided will.

2. Die Durchströmung des Beckens in Querrichtung reicht aus, da der Absetzvorgang bei der geringen Wassertiefe von Boden zu Boden wesentlich eher abgeschlossen ist.2. The flow through the basin in the transverse direction is sufficient because the Settling process with the shallow water depth from bottom to bottom much sooner completed is.

3. Die Anordnung von Kunststoffbahnen oder Folien (3) als bewegliche Zwiachen böden. Die Reinigung von den Absetzstoffen erfolgt bei dem oberen Teil der Folienschleife selbsttätig, bei dem unteren Teil sind Abstreifer (2) vorgesehen, die feststehend angeordnet sind.3. The arrangement of plastic sheets or foils (3) as movable Between floors. The cleaning of the sediments takes place in the upper part of the foil loop automatically, wipers (2) are provided for the lower part, which are arranged in a fixed manner.

4. Die Reinigung in der Einlaufrinne, der abgesetzten Stoffe erfolgt durch einen Eimer (4), der fortlaufend durch die Zinns gezogen wird und die Feststoffe nach oben austrggt.4. The cleaning in the inlet channel, the settled substances takes place by a bucket (4) that is continuously pulled through the tin and the solids discharges to the top.

Claims (1)

'In den sonstigen Sigensohaften ( Ablauf, Schlammtrichter und Schlammentnahi. aus den Trichtern entspricht das Becken den herkömmlichen Verfahren.'' In the other Sigensohaften (drain, sludge funnel and sludge removal. from the funnels, the basin corresponds to the conventional process. Die Vorteile gegenüber herkömmlichen Verfahren sind ein besserer Absetzt effekt und erhebliche Einsparungen im Bauvolumen bei der möglichen Herabsetzung der Aufenthaltszeiten.The advantages over conventional methods are better settling effect and considerable savings in construction volume in the event of a possible reduction the times of stay.
