Abstract

Apparatuses are known for introducing solid, liquid or gaseous treatment agent/nutrient into water or waste water which have a driven propeller freely arranged in the water and divide air supplied to the propeller into bubbles and produce a water/air bubble jet. The oxygen contained in the air diffuses into the water at the air/water interfaces. This can be designed, for example, with a hollow cone arranged in front of the propeller and having a multiplicity of orifices, stationary or rotating, as described in German Patent Specification 3139689 (C1). Rotating is more advantageous. Further means for bubble formation are newly described for apparatus according to this description, such as changeable rotational frequencies, vibration, changeable wall components containing orifices. Means are also newly described which reduce the amount of dirty water penetrating into the apparatus on backflow when the drive is shut off, which filter any water which does flow in, which accumulate the dirt therefrom upstream of the outlet orifices from where, detached again on restart, it is carried away. See Figure 4 for an air feed for very fine openings arranged in front of a water propeller and rotating with it and a stationary displacement body and lines for feeding solid or liquid treatment agent/nutrient from above the water surface to the propeller.

Description

Beschreibungdescription

Die Erfindung betrifft eine Vorrichtung zum Einbringen von Luft, insbesondere nach den Merkmalen des Oberbegriffs 1 gemäß Patent DE-P 31 39 689.The invention relates to a device for introducing air, in particular according to the features of preamble 1 according to patent DE-P 31 39 689.

Gegenstand des Hauptpatentes ist eine Vorrichtung der eingangs genannten Art, bei welcher vor dem Arbeitsraum des Axialrades eine Zuführvorrichtung für Behandlungsstoff angeordnet ist, die eine Vielzahl von kleinen Öffnungen aufweist. Diese Zuführvorrichtung kann stationär ausgebildet oder aber drehbar um die Axialradachse angeordnet sein.The subject of the main patent is a device of the type mentioned at the beginning Type in which a feed device for treatment material in front of the working space of the axial wheel is arranged, which has a plurality of small openings. This feeding device can be designed to be stationary or rotatable about the axial wheel axis.

Die letztere Ausbildung verdient den Vorzug.The latter training deserves preference.

Grundgedanke des Hauptpatentes ist es, die durch die Öffnungen austretenden " Fäden " von Luft an der Außenfläche der sich drehenden Zuführvorrichtung, also an den nach außen gerichteten Mündungen der Öffnungen abzuscheren, um die zugeführte Luft in eine Vielzahl feinster Bläschen mit einer insgesamt größeren Grenzfläche zum umgebenden Wasser, zu zerlegen.The basic idea of the main patent is that exiting through the openings "Strings" of air on the outer surface of the rotating feeder, that is at the outwardly directed mouths of the openings to shear off the fed Air in a multitude of very fine bubbles with an overall larger boundary surface to the surrounding water.

An ruhenden Zuführvorrichtungen mit Poren lösen sich entstehende Blasen, wie bekannt, erst ab, wenn ihr Auftrieb ausreicht um aufzusteigen, feinste Blasen entstehen aber so nicht.Bubbles that arise on stationary feed devices with pores loosen, As is known, only when their buoyancy is sufficient to rise, the finest bubbles but do not arise that way.

Obwohl gut bewährt, sind weitere Verbesserungen möglich.Although well-proven, further improvements are possible.

Der Mündungsbereich der sich gegen das Wasser bewegenden Öffnungen kann verschleißen.The mouth area of the openings moving against the water can wear out.

Um diese von Zeit zu Zeit zu erneuern, werden sie vorteilhaft in einer Wandung 16 vorgesehen, die gegen dem Trägerteil 15 der Zuführvorrichtung auswechselbar ist.In order to renew these from time to time, they will be beneficial in one Wall 16 is provided, which can be exchanged for the support part 15 of the feed device is.

Die gewünschte Bewegung der Zuführvorrichtung zum zu behandelndem Wasser kann in einfachster Weise dadurch vorgesehen sein, daß die Zuführvorrichtung sich mit dem Axialrad dreht.The desired movement of the feeder to the item to be treated Water can be provided in the simplest way that the feed device rotates with the axial gear.

Die Drehzahl kann aber auch vom Axialrad abweichend ausgebildet sein.However, the speed can also be designed differently from the axial gear.

In weiterer Ausgestaltung der Erfindung kann das Abreißen der austretenden Luftfäden dadurch verbessert werden, daß die Zuführvorrichtung einer Vibration ausgesetzt wird. Diese kann axial und/oder radial wirksam sein.In a further embodiment of the invention, the exiting can be torn off Air threads are improved by exposing the feeder to vibration will. This can be effective axially and / or radially.

Zur Anpassung an die jeweiligen Betriebsbedingungen ist vorzugweise vorgesehen, die Drehzahl und/oder die Amplitude der Vibration der Zuführvorrichtung änderbar zu gestalten.To adapt to the respective operating conditions, it is preferable provided, the speed and / or the amplitude of the vibration of the feeder to be changeable.

Zu diesem Zweck können alle bekannten Maßnahmen eingesetzt werden, also beispielsweise getriebliche und/oder elektrische Drehzahländerungsmaßnahmen.All known measures can be used for this purpose, for example gear and / or electrical speed change measures.

Die in der Hauptanmeldung genannten und die vorstehenden Mittel dienen dem verbessertem Bilden feiner Blasen, dem häufigen Verändern ihrer Oberfläche und damit besseren Möglichkeiten für das Eindiffundieren von in der Luft vorhandenem Sauerstoff ins zu behandelnde Wasser. Zu beachten sind jedoch auch Nachteile, die von im Wasser mitgeführtem Schmutz verursacht werden können.The means mentioned in the main application and the above means are used the improved formation of fine bubbles, the frequent changing of their surface and thus better possibilities for the diffusion of what is in the air Oxygen into the water to be treated. However, there are also disadvantages to consider, the can be caused by dirt carried in the water.

Wird bei einer, unter Wasser eingesetzten Vorrichtung nach DE-P 31 39 689 der Antrieb abgeschaltet, so laufen Wasserpropeller, Luftzuführes, Gebläserad bis zum Stillstandaus Das Zuführen und Eintragen von Luft ins Wasser ist beendet.Is used in a device used under water according to DE-P 31 39 689 the drive is switched off, so the water propellers run, Air supply, Fan wheel until it comes to a standstill The supplying and drawing in of air into the water is finished.

Als Folge kann das bisher durch den Lufteintrag verdrängte, zu behandelnde Wasser durch die Öffnungen 6 des Luftzuführers, sowie bei umlaufenden zu feststehenden Bauteilen erforderlichen Spalte 17 in den Luftzuführer 10 und den unter Wasser befindlichen Teil 20 der Luftzuleitung eindringen, bis es im Inneren des Luftzuführ-Rohres 2o etwa die Höhe des Wasserspiegels erreicht.As a result, that which has previously been displaced by the entry of air can be treated Water through the openings 6 of the air feeder, as well as with rotating to fixed Components required column 17 in the air feeder 10 and the underwater Part 20 of the air supply line penetrate until it is inside the air supply pipe 2o reached about the height of the water level.

Bei neuem Start wird das Wasser, Abwasser in entgegengesetzter Richtung wieder herausgeschleudert, herausgesaugt, von nachfolgender Gebläseluft herausgedrückt.With a new start the water, sewage in the opposite direction thrown out again, sucked out, pushed out by the following blower air.

Bei Dauerbetrieb, sauberem Wasser ist dies nicht nachteilig.This is not a disadvantage in continuous operation, with clean water.

Bei Einsatz in verschmutztem Wasser, öfterem Start und Stop, kann vom eindringenden Wasser mitgeführter Schlamm jedoch Öffnungen zusetzen, an Innenflächen anhaften, in Lagerungen eindringen und dadurch Betriebsstörungen verursachen.When used in polluted water, with frequent start and stop, the However, clog the sludge carried along by the penetrating water on inner surfaces stick, penetrate into bearings and thereby cause malfunctions.

Ein Rückschlag-Ventil für Luft 8 an Zuführrohr 20 über Wasser, würde zwar dort das Ausströmen von Luft verhindern. Die, über dem im Wasser liegendem Zuführer lo, stehende Wassersäule schiebt jedoch, da 770 mal schwerer, die nunmehr eingeschlossene Luft, durch die Öffnungen 6 und Spalte 17 eindringend trotzdem in den Innenraum 18 von Luftstutzen 9 und Rohr 20 zurück, dem Schmutzwasser den Weg bis etwa in Höhe des Wasserspiegels freimachend. Betriebsstörungen sind damit nicht zu vermeiden.A check valve for air 8 on supply pipe 20 above water would be prevent air from escaping there. The one above the one lying in the water Feeder lo, standing water column pushes, however, because it is 770 times heavier, that now trapped air, penetrating through the openings 6 and gaps 17 anyway the interior 18 of the air nozzle 9 and pipe 20 back, the dirty water the way clearing to about the height of the water level. Operational disruptions are not with it to avoid.

Geeigneter sind die folgenden erfindungsgemäßen Mittel: Verlangsamen des sonst schnellen Eindringens von Wasser mittels geringer gesamter Querschnittsfläche von Öffnungen 6 und Spalten 17.The following agents according to the invention are more suitable: Slowing down the otherwise rapid penetration of water due to the small total cross-sectional area of openings 6 and gaps 17.

Vermindern des Volumens der Innenräume von 9, 18, 20 die eindringendes Wasser ausfüllen kann, könnte, beispielsweise mittels Verdrängerkörper 19.Reducing the volume of the interiors of 9, 18, 20 the penetrating Can fill water, could, for example by means of displacement body 19.

Feinste Öffnungen 6 und enge Spalte 17 die das Schmutzwasser filtern, den Schmutz von Schmutzwasser vor ihnen zurückhalten, anlagern.Finest openings 6 and narrow gaps 17 that filter the dirty water, hold back the dirt of dirty water in front of them, deposit it.

Beibehalten der Luftzufuhr bis die Vorrichtung auf geringe Wassertiefe angehoben, vorzugsweise der Zuführer- für die von ihm zum Propeller fließende Luft -aus dem Wasser herausgehoben ist.Maintain the air supply until the device is shallow raised, preferably the feeder for the air flowing from it to the propeller -is lifted out of the water.

Außer Sauerstoffgas oder sauerstoffhaltiger Luft als Lebensstoff für, organischen Schmutz abbauende Bakterien, kann zusätzlich, fester oder flüssiger Wahrtin#ss#off für Lebewesen, wie Fische oder dgl. beispielsweise mit Rohren 21, 22 von über Wasser bis in den Arbeitsraum von Axialrad, Propeller 1 eingebracht und mit seinem Wasser-Luftblasen-Strahl in der Wassermasse verteilt werden.Except for oxygen gas or oxygen-containing air as food for, organic dirt-breaking bacteria, can be additional, solid or liquid True # ss # off for living beings, such as fish or the like, for example with pipes 21, 22 introduced from above water into the working space of the axial wheel, propeller 1 and be distributed in the body of water with its water-air-bubble jet.
