Zusatz zum, Patent 281129.Addendum to, patent 281129.

Patentiert im Deutschen Reiche vom 30. Mai 1916 ab. Längste Dauer: 16. Januar 1929.Patented in the German Empire on May 30, 1916. Longest duration: January 16, 1929.

Bei dem Zulaufgerinne gemäß dem Hauptpatent bleibt zwischen der Unterkante der seitlichen Wände desselben und der Sohle der Absitzbecken ein größerer Schlitz frei, durch welchen die schweren Sinkstoffe direkt nach dem' Faulraum abgeschieden werden.In the inlet channel according to the main patent remains between the lower edge of the side walls of the same and the sole of the weaning basin a larger slit free through which the heavy suspended matter is deposited directly after the 'septic tank.

Es hat sich gezeigt, daß Fälle eintreten können, in denen es wünschenswert ist, die Absitzräume von dem Faulraum zeitweise vollständig zu trennen, um jede Verbindung der Räume unter sich aufzuheben.It has been shown that cases can arise in which it is desirable that the Completely separate settling rooms from the septic tank at times in order to ensure that there is no connection between the To pick up spaces below.

Dies wird, ohne an dem Gerinne selbst bzw. an seiner Anordnung zwischen den Absitzräumen und dem Faulraum irgend etwas zu ändern, dadurch erreicht, daß die inneren Wände des Zulaufgerinnes beweglich angeordnet oder mit einer verschiebbaren Doppelwand ausgerüstet sind, so daß sie bis auf die Sohle der unterhalb des Gerinnes befindlichen schrägen Fläche gesenkt werden können.This is done without affecting the channel itself or its arrangement between the settling rooms and to change something in the digester, achieved in that the inner walls of the inlet channel are movably arranged or are equipped with a sliding double wall so that they are down to the sole the inclined surface located below the channel can be lowered.

Der Zweck, der durch diese Einrichtung erreicht wird, besteht darin, den in den Absitzräumen gesammelten Schlamm von Zeit zu Zeit dem Faulraum zuzuführen, ohne daß der Klärbetrieb irgendeine Unterbrechung erfährt, oder das in den Klärbecken befindliche Frischwasser beunruhigt oder der abgelagerte Schlamm aufgewirbelt wird.The purpose achieved by this facility is that of the settling rooms to feed collected sludge from time to time into the septic tank without the sewage plant experiences any interruption, or the one in the clarifier Fresh water is disturbed or the deposited sludge is whirled up.

Dies geschieht in der Weise, daß die beweglichen, gegen den Faulraum gelegenen Wände des Zulaufgerinnes bis auf die Sohle der unterhalb des Gerinnes befindlichen schrägen Fläche gesenkt werden, wodurch ein Abschlußzwischen Faulraum und Absitzräumen erzielt wird. Es entsteht nun entweder durch Aufstau in den Absitzräumen oder durch Senken des Wasserspiegels im Faulraum ein Druckunterschied, der in bekannter Weise dazu benutzt wird, den in den Absitzräumen gesammelten Schlamm durch geeignete, mit Abschlußschiebern ο. dgl. versehene Rohrleitungen in den Faulraum zu befördern.This is done in such a way that the movable ones are located against the septic tank Walls of the inlet channel except for the sole of the sloping side below the channel Area can be lowered, creating a seal between the septic tank and settling rooms is achieved. It now arises either through damming up in the settling rooms or through lowering of the water level in the digester is a pressure difference that is used in a known manner the sludge collected in the settling rooms through suitable, with closing valves ο. Like. Provided pipelines to convey into the digester.

Das Senken der Tauchwände oder der Fallentafeln sowie das Ziehen der Schieber wird zweckmäßig durch einfache Hebelverbindungen bewirkt, wobei Schlammleitungsrohre günstigerweise in den Faulraum derart ausmünden, daß der die Anlage bedienende Arbeiter den Übertritt des Schlammes aus den Absitzräumen nach dem Faulraum beobachten kann. Um nicht gezwungen zu sein, den ganzen Wasserspiegel des Faulraumes zu senken und damit eine nicht unbeträchtliche Wassermenge ablassen zu müssen, · kann in demselben auch ein unten offener Kasten derart angeordnet werden, daß zwischen dessen senkrechten Wänden und den inneren Tauchwänden des Zulaufgerinnes ein freier Zwischenraum verbleibt, so daß beim Ablassen dieser Wasserspiegel nur allein gesenkt wird, während der unter dem Kasten befindliche Wasserspiegel durch die atmosphärische Luft im Gleichgewicht gehalten wird.Lowering the baffles or trap boards as well as the pulling of the slide is expediently effected by simple lever connections, with mud pipes advantageously Open out into the septic tank in such a way that the worker operating the system prevents the sludge from passing over from the settling rooms can watch after the septic tank. So as not to be forced to do the whole thing To lower the water level of the digester and thus a not inconsiderable amount of water To have to drain, a box open at the bottom can also be arranged in the same be that between its vertical walls and the inner baffles of the inlet channel a free space remains, so that when draining this water level only is lowered alone, while the water level under the box by the atmospheric air is kept in equilibrium.

Auf der Zeichnung ist eine solche Vorrich-Such a device is shown in the drawing.

Claims

turig illustrated by FIGS. 1 to 3 i ⁿ two embodiments, namely shows:

Fig. Ι a longitudinal section through a system of the first embodiment,
Fig. 2 is a plan view of this, and

3 shows a longitudinal section according to the second embodiment.

The sewage treatment plant consists in a known manner of the settling spaces α and the digestion chamber b arranged between them. These two rooms will be. separated by the walls of the inlet channel, which are designed as baffles c, d , in such a way that the inflowing sewage coarsely excrete the waste materials carried along in the channel, with the heavy suspended matter sliding off immediately after the septic tank, while the lighter suspended matter as well as the suspended matter and floating matter pass through the Wastewater can be led into the settling rooms and is only gradually excreted there. The sludge thus accumulated on the bottom of the settling rooms α is transported from time to time to the septic tank b , and this is done in a known manner in that the water level in the septic tank b is lowered compared to that in the settling rooms a. From the settling rooms α , pipes e, which can be closed by slides f , lead to the septic tank b. In order to lower the water level in the septic tank, it is necessary that the same can be separated from the settling rooms. This is done either by lowering the inner immersion walls d of the inlet channel or by lowering the trap panels brought into connection with these, which can be set down by suitable devices up to the inclined surface located below the inlet channel and thereby form a seal between the septic tank and the settling room. If the water level in the septic tank is lowered to the required depth, the slides f of the pipes e are opened, whereupon the overpressure prevailing in the settling rooms pushes the sludge that has accumulated on their bottom towards the septic tank. The arrangement of the pipes that can be closed by the slide f has the advantage that the hydraulic overpressure that is present comes into effect immediately when the slide is opened and the sludge is pressed under all circumstances towards the septic tank. In addition, the operating worker can observe at any time whether sludge is still flowing out of the respective settling room or whether the same has already been withdrawn, whereupon the next slide is opened and so on, until all settling rooms have given their sludge to the digester.

In order to avoid that the entire water level of the septic tank has to be lowered, a box g, open at the bottom, can be installed in the same, with a gap between its vertical walls and the inner baffles d of the inlet channel. When the water level falls, only the part of the water level surface located in this gap is then lowered, while the part located in the box does not participate in this lowering because it is kept in equilibrium by the atmospheric air.

Sponsorship τ claim:

Inlet channel for sewage clarifiers according to patent 281129, characterized in that that the inner walls of the inlet channel up to the sole of the inclined surface located below the channel can be lowered.
