Abstract
In a system for the treatment of liquid manure and other sewage before its discharge into the drainage system, air is introduced into the fluid through aerator nozzles. The basin includes a revolving stirring mechanism and each stirrer blade is fitted with nozzles which are connected to an air compressor. This avoids the frequent blockages caused by air injector atomizer nozzles and requires a much lower power input.
Description
Im Zuge der Wirtschaftlichkeit und Rationalisierung wird die Flüssigentmistung zunehmend angewendet. Dabei entstehen gewisse Nachteile bei der Güllenlagerung gegen über der Mistlagerung.
Zur Kompensation dieser Nachteile, wie Geruchbelästigung beim Ausbringen, Verschmutzung von Oberflächengewässern und Grundwasser usw., wird die lagernde Gülle belüftet.
Zu diesem Zwecke ist bereits vorgeschlagen worden, einen die Luft ansaugenden Injektor zu verwenden; der austretende Jauchestrahl wird dabei in feinste Tropfen verteilt, um die relative Kontaktfläche zwischen Luft und Jauche gross zu halten. Derartige Anlagen sind jedoch störanfällig und weisen einen verhältnismässig grossen Leistungsbedarf auf.
Diese Nachteile sollen durch die vorliegende Erfindung behoben werden. Das den Gegenstand der Erfindung bildende Verfahren ist demgemäss dadurch gekennzeichnet, dass der Eintrag der Luft mittels Düsen im Bereich der Flügel eines in die Jauche bzw. das Abwasser eintauchenden Rührwerkes erfolgt.
Die zur Durchführung dieses Verfahrens dienende Einrichtung weist ein Rührwerk auf, das eine rotierend angetriebene Welle und mindestens einen an dieser drehstarr befestigten Rührflügel besitzt. Diese Einrichtung ist erfindungsgemäss dadurch gekennzeichnet, dass der bzw. jeder Rührflügel mit Luftdüsen versehen und über Luftleitungen mit einem Luftkompressor verbunden ist. Die rotierend angetriebene Welle besteht zweckmässigerweise aus einem Rohr, durch welches die Luft zugeführt wird.
Diese Welle kann an ihrem oberen Ende ein Kupplungsstück, an ihrem unteren Ende einen Spurlagerzapfen aufweisen. In diesem Falle kann es zweckmässig sein, dass die Luftleitungen in das Kupplungsstück undioder in den Spurlagerzapfen der Welle münden.
Für das Flügelrührwerk und einen Kompressor sind vorzugsweise zwei Elektromotoren vorgesehen, die unter Einschaltung eines Freilaufs gegenseitig mechanisch gekuppelt sein können.
Auf der einzigen Figur der beiliegenden Zeichnung ist ein Ausführungsbeispiel einer zur Durchführung des erfindungsgemässen Verfahrens dienenden Einrichtung dargestellt.
Die einen Vertikalschnitt darstellende Figur zeigt in schematischer Weise eine Jauchegrube 1, in welcher sich ein in seiner Gesamtheit mit 2 bezeichnetes Rührwerk befindet.
Das Rührwerk 2 besitzt eine Antriebswelle 3, die über horizontale Stege 4 mit den Rührflügeln 5 verbunden ist. Die Antriebswelle 3 ist als Hohlwelle ausgebildet und dient zur Zufuhr der zur Belüftung der Jauche erforderlichen Luft. Von einem Kompressor 6 aus gelangt die Druckluft über eine Leitung 7 in die Hohlwelle, von wo aus sich die als Rohre ausgebildeten Stege 4 zu den Rührflügeln 5 gelangt. Über Düsen wird die Druckluft dann im Bereiche der rotierenden Rührflügel 5 feinblasig in die Jauche verteilt.
Während die Druckluftleitung 7 über einen mit 3a bezeichneten Spurlagerzapfen der Antriebswelle 3 in dieselbe gelangt, kann eine zweite Druckluftleitung 9 von oben über ein Kupplungsstück 11 in die Antriebswelle 3 münden. Die im Sinne der Pfeile 8 rotierende Welle erteilt den Rührflügeln 5 eine Rotationsbewegung, wodurch der gesamte Inhalt der Jauchegrube in Bewegung gehalten wird. Das Ausblasen der Druckluft durch die Düsen 10 erfolgt vorzugsweise wäh- rend der Rotation der Rührflügel 5.
Das oberhalb der Jauchegrube angeordnete Antriebsaggregat weist einen Getriebekasten 12 auf, auf welchem ein Rührwerkmotor 13 sowie der bereits erwähnte Luftkompressor 6 mit dem zugehörigen Kompressorantriebsmotor 14 an geordnet sind. Die beiden Elektromotoren 13 und 14 sind über ein Keilriemenpaar 15 miteinander verbunden, wobei in diesem Antriebssystem ein als Überholkupplung arbeiten der Freilauf vorgesehen ist.
Über ein weiteres Keilriemenpaar 16 ist der Antriebsmo tor 13 mit dem im Getriebekasten 12 angeordneten Ge triebe verbunden.
Die beschriebene erstmalige Anwendung des Lufteintra ges über das Flügelrührwerk soll bezüglich der Hygiene zur spürbaren Verbesserung der Umweltbedingungen beitragen.
Auf diese Art und Weise ist es möglich, dass die mit Sauer stoff homogen durchmischte Gülle der Landwirtschaft gefahr loser zur Bodenverbesserung übergeben werden kann.
Die beschriebene Einrichtung kann vom Fachmann in mannigfacher Weise abgewandelt werden. So ist es beispielsweise auch möglich, die Druckluft der als Hohlwelle ausgebildeten Antriebswelle 3 über ein ringförmiges Schleifringsystem zuzuführen. Der Getriebekasten 12 ist dabei vorzugsweise als Luftspeicherraum ausgebildet und weist ein unteres festes Abschlussblech 12a auf, durch welches ein rotierendes Mantelrohr mit Schleifringdichtung hindurchragt.
Durch den Eintrag von Luft mittels der Rührflügel 5 wird sowohl die Jauche ständig umgewälzt, als auch der Sauerstoff in fein dosierter Form der Jauche zugeführt.
Dadurch steigt die Lebensfähigkeit der Bakterien, die unangenehmen Geruchsstoffe werden abgebaut und die Krankheitserreger werden durch die sauerstofffreundlichen Mikroorganismen eliminiert. Die auf diese Weise behandelte Gülle kann mit einem hohen mineralischen Nährwert auf landwirtschaftlichen Kulturen ausgebracht werden.
Das aus Kompressor 6 und Antriebsmotor 14 bestehende Druckluftaggregat muss selbstverständlich nicht unbedingt auf dem Rührwerkmotor aufgebaut sein. Es ist auch möglich, dieses Druckluftaggregat an einem unabhängigen Standort mit eigenem Elektromotorantrieb zu versehen.
Bei der auf der Zeichnung dargestellte Kupplung von Rührwerkmotor 13 und Kompressorantriebsmotor 14 ergeben sich zwei grundsätzliche Betriebszustände: a) Zwecks Homogenisierung der Jauche setzt der Rührwerkmotor die Rührflügel 5 in rotierende Bewegung. Der Kompressormotor ruht, weil der eingebaute Freilauf die Kraftübertragung verhindert.
b) Zwecks Belüftung der Jauche überträgt der Kompressormotor einen Teil seines Drehmomentes auf den Rührwerkmotor und dieser über das Rührwerkgetriebe auf die Antriebswelle 3, die sich nun mit geringerer Drehzahl bewegt.
Das Einblasen der Luft kann beispielsweise zusätzlich durch Düsen 17 erfolgen, welche unterhalb der Rührflügel 5 angeordnet sind und durch eine Leitung 17 vom Kompressor 6 aus gespeist werden.

**WARNUNG** Ende DESC Feld konnte Anfang CLMS uberlappen**.
In the course of economic efficiency and rationalization, liquid manure removal is increasingly used. Certain disadvantages arise in the case of slurry storage compared to manure storage.
To compensate for these disadvantages, such as odor nuisance when spreading, pollution of surface water and groundwater, etc., the stored liquid manure is aerated.
For this purpose it has already been proposed to use an injector which draws in air; the exiting liquid manure jet is distributed in the finest drops in order to keep the relative contact area between air and liquid manure large. Such systems are, however, prone to failure and have a relatively large power requirement.
The present invention is intended to remedy these disadvantages. The method forming the subject of the invention is accordingly characterized in that the air is introduced by means of nozzles in the area of the blades of an agitator immersed in the liquid manure or the sewage.
The device used to carry out this method has an agitator which has a rotatingly driven shaft and at least one agitator blade attached to it in a torsionally rigid manner. According to the invention, this device is characterized in that the or each agitator blade is provided with air nozzles and is connected to an air compressor via air lines. The rotating driven shaft expediently consists of a tube through which the air is supplied.
This shaft can have a coupling piece at its upper end and a thrust bearing pin at its lower end. In this case, it can be useful for the air lines to open into the coupling piece and / or into the journal bearing journal of the shaft.
For the vane agitator and a compressor, two electric motors are preferably provided, which can be mechanically coupled to one another with a freewheel.
In the single figure of the accompanying drawing, an embodiment of a device serving to carry out the method according to the invention is shown.
The figure showing a vertical section shows schematically a cesspool 1 in which there is an agitator designated in its entirety by 2.
The agitator 2 has a drive shaft 3 which is connected to the agitator blades 5 via horizontal webs 4. The drive shaft 3 is designed as a hollow shaft and serves to supply the air required for ventilating the liquid manure. From a compressor 6, the compressed air reaches the hollow shaft via a line 7, from where the webs 4 designed as tubes reach the agitator blades 5. The compressed air is then distributed in fine bubbles into the liquid manure in the area of the rotating agitator blades 5 via nozzles.
While the compressed air line 7 enters the drive shaft 3 via a thrust bearing pin labeled 3a, a second compressed air line 9 can open into the drive shaft 3 from above via a coupling piece 11. The shaft rotating in the direction of the arrows 8 gives the agitator blades 5 a rotational movement, whereby the entire contents of the cesspool are kept in motion. The compressed air is blown out through the nozzles 10 preferably while the agitator blades 5 are rotating.
The drive unit arranged above the cesspool has a gear box 12 on which an agitator motor 13 and the aforementioned air compressor 6 with the associated compressor drive motor 14 are arranged. The two electric motors 13 and 14 are connected to one another via a pair of V-belts 15, with a freewheel operating as an overrunning clutch being provided in this drive system.
About another pair of V-belts 16 of the Antriebsmo gate 13 is connected to the gearbox arranged in the gearbox 12 Ge.
The described first-time application of the Lufteintra sat on the wing agitator should contribute to a noticeable improvement in environmental conditions in terms of hygiene.
In this way, it is possible that the manure, mixed homogeneously with oxygen, can be handed over to agriculture more safely for soil improvement.
The device described can be modified in many ways by the person skilled in the art. For example, it is also possible to supply the compressed air to the drive shaft 3, which is designed as a hollow shaft, via an annular slip ring system. The gear box 12 is preferably designed as an air storage space and has a lower fixed cover plate 12a through which a rotating jacket tube with a slip ring seal protrudes.
By introducing air by means of the agitator 5, both the liquid manure is constantly circulated and the oxygen is added to the liquid manure in finely dosed form.
This increases the viability of the bacteria, the unpleasant odor substances are broken down and the pathogens are eliminated by the oxygen-friendly microorganisms. The manure treated in this way can be applied to agricultural crops with a high mineral nutritional value.
The compressed air unit consisting of compressor 6 and drive motor 14 does not necessarily have to be built on the agitator motor, of course. It is also possible to equip this compressed air unit with its own electric motor drive at an independent location.
The coupling of the agitator motor 13 and compressor drive motor 14 shown in the drawing results in two basic operating states: a) For the purpose of homogenizing the liquid manure, the agitator motor sets the agitator blades 5 in a rotating motion. The compressor motor rests because the built-in freewheel prevents power transmission.
b) In order to ventilate the liquid manure, the compressor motor transmits part of its torque to the agitator motor and this, via the agitator gearbox, to the drive shaft 3, which now moves at a lower speed.
The air can also be blown in, for example, through nozzles 17, which are arranged below the agitator blades 5 and are fed from the compressor 6 through a line 17.
The air can also be blown in, for example, through nozzles 17, which are arranged below the agitator blades 5 and are fed from the compressor 6 through a line 17.
