Abstract
Description
Die Erfindung bezieht sich auf einen zur Reinigung von mit Schwimm und Sinkstoffen verschmutzten Abwässern geeigneten Abscheider, der eine im wesentlichen horizontal durchströmte Beruhigungskammer und eine dem Zulauf vorgeschaltete Trennstrecke enthält (nach Patentanmeldung P 41 00 822). Entlang der Trennstrecke haben die unterschiedlich warmen Abwässer bereits Gelegenheit, sich entsprechend ihrer Dichte nach oben oder unten zu schichten und damit bereits eine Vorabscheidung herbeizuführen. Die nach unten geschichteten kalten Abwässer enthalten in der Regel Sinkstoffe, wie z. B. Kartoffelstärke, und die nach oben zu leitenden warmen Abwässer tragen Leichtstoffe, wie z. B. Öle und Fette, die aus der Geschirr- und Gerätespülung aus Küchenbetrieben stammen.The invention relates to a for cleaning with floating and sediments contaminated waste water suitable separator, the a calming chamber with essentially horizontal flow and contains a separating section upstream of the inlet (after Patent application P 41 00 822). Along the line, they have differently warm wastewater already opportunity to layer up or down according to their density and to bring about a preliminary separation. The down stratified cold wastewater usually contains suspended matter, such as B. potato starch, and the warm to be conducted upwards Waste water carries light materials such as B. oils and fats from the Dishwashing and appliance washing come from kitchen businesses.
Mit der Erfindung soll die Aufgabe gelöst werden, Verwirbelungen der Abwasser-Teilströme entlang der Trennstrecke oder am Eintritt in die Beruhigungskammer zu vermeiden. Solche Verwirbelungen könnten den Erfolg der Temperaturschichtung wieder zunichte machen. Die Aufgabe wird erfindungsgemäß durch am Ende der Trennstrecke in Strömungsrichtung verlaufende Leitbleche zum ablösungsfreien Abgrenzen und Laminarisieren der Schichtströme gelöst. Die Leitbleche können einzeln oder als Paket quer zur Strömungsrichtung einstellbar sein. Ihre Anordnung kann entsprechend der Strömungsspreizung fächerförmig sein. Bei Gefahr von Ablagerungen kann es zweckmäßig sein, die Leitbleche nach unten abklappbar zu machen, so daß die Ablagerungen abrutschen.The object of the invention is to achieve turbulence of the partial wastewater flows along the separation section or at the inlet to avoid in the calming chamber. Such swirls could negate the success of temperature stratification. The object is achieved by at the end of the separation section in Directional baffles for non-detachable Delimitation and laminarization of the layer currents solved. The Baffles can be used individually or as a package across the flow direction be adjustable. Your arrangement can be according to the Flow spread be fan-shaped. If there is a risk of deposits it may be appropriate to fold down the baffles make so that the deposits slip off.
In der Zeichnung sind diese und andere Ausgestaltungen im einzelnen dargestellt. Fig. 1 zeigt in der Seitenansicht einen vertikalachsig rotationssymetrischen Abscheider 1 mit tangential angeordneter konischer Trennstrecke 2, die etwas oberhalb der Höhenmitte in die Beruhigungskammer 3 mündet. Aus der Draufsicht (Fig. 2) ist auch der Reinwasser-Ablauf 4 zu ersehen, der hier in der Achse der Beruhigungskammer 3 beginnt und radial nach außen verläuft. Auf diese Weise stellt sich im Betrieb des Abscheiders eine Rotationsströmung ein, die spiralförmig von außen nach innen verläuft und einen sehr langen Abscheideweg für die Schwimm- und Sinkstoffe ergibt. Die Rotationsbewegung begünstigt gleichzeitig das Wandern der abgetrennten Schmutzstoffe entlang der Konusflächen 5, 6 zu den an deren Spitzen liegenden Austragöffnungen (nicht dargestellt).These and other configurations are shown in detail in the drawing. Fig. 1 shows a side view of a vertical-axis rotationally symmetrical separator 1 with a tangentially arranged conical separating section 2 , which opens into the settling chamber 3 somewhat above the height center. From the top view ( FIG. 2), the pure water outlet 4 can also be seen, which begins here in the axis of the calming chamber 3 and extends radially outwards. In this way, a rotation flow occurs during operation of the separator, which runs in a spiral from the outside inwards and results in a very long separation path for the floating and sinking substances. The rotational movement simultaneously favors the migration of the separated contaminants along the conical surfaces 5 , 6 to the discharge openings located at their tips (not shown).
In der trichterförmig erweiterten Trennstrecke 2 liegen vier Leitbleche 7 übereinander in leicht gespreizter Anordnung entsprechend dem Öffnungswinkel der konischen Trennstrecke. Die Leitbleche 7 sind auch radial nach innen erweitert, so daß die sich einstellenden Teilströme beim Eintritt in die Beruhigungskammer gegeneinander bzw. gegen den rotierenden Wasserkörper abgegrenzt werden. In the funnel-shaped separating section 2 , four guide plates 7 lie one above the other in a slightly spread arrangement corresponding to the opening angle of the conical separating section. The baffles 7 are also expanded radially inwards, so that the partial streams which occur are delimited from one another or from the rotating water body as they enter the settling chamber.
Um eventuelle Ablagerungen auf den Leitblechen beseitigen zu können, sind diese klappbar gelagert. Am hinteren Ende sind Schwenkachsen 8 in Taschen 9 der Trennstrecke gelagert, und die Vorderkanten der Leitbleche stecken in einer Schiebeleiste 10, die mit die Leitbleche beidseitig umfassenden Stiften 11 ausgestattet ist. Anstelle der Schwenkachsen kann die Hinterkante der Leitbleche flexible Biegeleisten bekommen, die fest eingespannt sind. Um jedes Leitblech einzeln einstellen oder rütteln zu können, wäre jedes Leitblech mit einer eigenen Stellstange zu versehen. Die Leitbleche könnten auch vertikal oder schräg angeordnet sein, so daß sich das Problem der Ablagerungen nicht ergibt. Schließlich können die Leitbleche aus einem lipophoben, d.h auf die abzutrennenden Leichtstoffe abstoßend wirkenden Material hergestellt sein, so daß es gar nicht erst zu Ablagerungen kommt.In order to be able to remove any deposits on the guide plates, they are hinged. At the rear end, pivot axes 8 are mounted in pockets 9 of the separating section, and the front edges of the guide plates are inserted in a sliding bar 10 which is equipped with pins 11 which comprise the guide plates on both sides. Instead of the swivel axes, the rear edge of the guide plates can have flexible bending strips that are firmly clamped. In order to be able to individually adjust or shake each guide plate, each guide plate would have to be provided with its own adjusting rod. The baffles could also be arranged vertically or obliquely, so that the problem of deposits does not arise. Finally, the baffles can be made of a lipophobic material, that is, a material that has a repellent effect on the light substances to be separated, so that deposits do not occur in the first place.
In Fig. 3 ist eine Variante der Leitbleche von Fig. 1 und 2 gezeigt. Die Leitbleche 17 haben hier die Form von Schiffskielen, wobei der Kiel 18 in Strömungsrichtung nach unten stärker absinkt und der Faltwinkel 19 entsprechend kleiner wird. Die unteren Teilströme des thermisch geschichteten Abwassers werden daher stärker gebündelt und gerichtet und begünstigen das Abtrennen der Sinkstoffe. Auch hier sind Abwandlungen möglich. So können die gefalteten Leichtbleche durch vietelkreisförmig gebogene Kegelmantelflächen ersetzt werden. Auch eine Wellenform über die ganze Breite ist denkbar und sinnvoll. Zum Abwerfen von Ablagerungen können die Hälften der V-förmigen Leitbleche einzeln nach unten gekippt werden.In FIG. 3, 1 and 2 is a variation of the baffles of FIG.. The guide plates 17 here have the shape of ship's keels, the keel 18 sinking more downward in the direction of flow and the folding angle 19 becoming correspondingly smaller. The lower sub-streams of the thermally layered wastewater are therefore bundled and directed more strongly and promote the separation of the sediments. Modifications are also possible here. In this way, the folded light sheets can be replaced by conical outer surfaces curved in a circle. A waveform across the entire width is also conceivable and useful. The halves of the V-shaped baffles can be individually tilted down to throw off deposits.
