Vorrichtung für die Befestigung einer Opferanode in WasserbehälternDevice for fastening a sacrificial anode in water tanks

Pur den kathodischen Korrosionsschutz der Behälterwandungen finden Metallstäbe Verwendung, deren Werkstoff in der elektrochemischen Spannungsreihe ein niedrigeres Potential aufweist als das des Behälterwerkstoffes. Es fließt ein Schutzstrom, dessen Stromstärke von der Leitfähigkeit des gespeicherten Wassers abhängig ist. Um einerseits eine zu geringe Stromstärke zu verhindern und zum andern einen zu raschen Abtrag des Anodenmaterials zu vermeiden, wird angestrebt, die Stromstärke in gewissen Grenzen konstant zu halten. Zu diesem Zweck ist es bekannt geworden, den Anschluß der Anode isoliert nach außen zu führen und in die Verbindungsleitung zur Behälterwand je nach Bedarf einen elektrischen Widerstand oder eine Fremdstromquelle zu schalten.Find the cathodic protection of the tank walls against corrosion Use of metal rods whose material in the electrochemical series has a lower potential than that of the container material. A protective current flows, the strength of which depends on the conductivity of the stored water. Around On the one hand, to prevent a current that is too low and, on the other hand, to avoid too rapid erosion of the anode material, the aim is to to keep the current strength constant within certain limits. For this purpose it has become known to connect the anode insulated to lead to the outside and in the connection line to the container wall an electrical resistor or a To switch external power source.

Die bekannte Lösung, den Korrosionsschutzstab pendelnd in dem Behälter aufzuhängen und lediglich die Anodenanschlußleitung isoliert nach außen zu führen, hat den Nachteil, daß die Anode beim Transport besonders befestigt werden muß. Es sind auch starre, isoliert ausgeführte Anodenbefestigungen bekannt geworden, bei denen außerhalb des Behälters ein gewisser Raum für die Einbringung oder Befestigung der Anode erforderlich ist. Dieser Raum ist bei Heizungskesseln mit eingebauten Speicherbrauchwasserbereitern, in denen die Anode vertika angeordnet ist, häufig nicht vorhanden.The well-known solution, the anti-corrosion rod oscillating in the container hang up and only to lead the anode connection line insulated to the outside, has the disadvantage that the anode during transport must be specially fastened. There are also rigid, isolated ones Anode fastenings have become known in which a certain space outside the container for the introduction or fastening the anode is required. This space is for heating boilers with built-in storage water heaters in which the anode is vertically is arranged, often does not exist.

Aufgate der Erfindung iat es, eine Befestigungsmöglichkeit für den Finbau einer Anode in einen Behälter zu finden, die bei elektrisch isolierter Durchführung eine starre Verbindung mit der Behälterwand herstellt und bei der die Anode vom Innenraum des Behälters aus in die Befestigungsvorrichtung eingebaut werden kann.On the basis of the invention, it is possible to attach the To find the finbau of an anode in a container, which has a rigid connection with the electrically insulated implementation Produces container wall and in which the anode are built into the fastening device from the interior of the container can.

In den Zeichnungen wird -ein Ausführungsbeispiel der erfindungsgemäßen lösung der gestellten Aufgabe dargestellt und zwar zeigt Fig. 1 einen Querschnitt durch die Befestigungsvorrichtung Fig. 2 eine Draufsicht auf die Befestigungsvorrichtung.In the drawings, an embodiment of the invention solution of the problem presented, namely Fig. 1 shows a cross section through the fastening device Fig. 2 is a plan view of the fastening device.

An den Behältermantel 1 ist ein Rohrstück 2 angeschweißt, in das die Anode 3 mit dem aufgeschraubten Gewindebolzen 5 vom Behälterinneren her hineingeschoben wird. Die Anodenseele 4 wird am oberen Ende mit dem Gewindebolzen 5 verschweißt. Der Gewindestift 6 dient zur Befestigung der Anodenanschlußleitung. Durch die Dichtungen 7,8 und 9 wird die Anode mitsamt den Gewindebolzen 5 gegen den Behältermantel 1 elektrisch isoliert und nach außen abgedichtet, nachdem der Gewindebolzen durch die Sechskantmutter 11 über die Zwischenscheibe 10 unter Zwischenlage der Isolierdichtungen fest gegen das Rohrstück 2 angezogen wurde. Bei der gezeichneten Vorrichtung erfolgt die Verschraubung von außen. Die Anode wird über ein Mannloch in den Behälter eingebracht. Die erforderliche Montagehöhe oberhalb des Behälters bei senkrechtem Einbau der Anode ist also äußerst gering.A pipe section 2 is welded to the container jacket 1, into which the anode 3 with the screwed-on threaded bolt 5 is pushed from the inside of the container. The anode core 4 is at the top The end is welded to the threaded bolt 5. The threaded pin 6 is used to attach the anode connection line. Through the seals 7, 8 and 9, the anode together with the threaded bolts 5 is electrically isolated from the container jacket 1 and sealed from the outside, after the threaded bolt through the hexagon nut 11 over the washer 10 with the interposition of the insulating seals was tightened against the pipe section 2. In the device shown, the screw connection is made from the outside. The anode is over a manhole was made in the container. The required mounting height above the container when the anode is installed vertically is so extremely low.
