Abstract

A frame (e.g. of asbestos reinforced cresolic plastic) to hold a graphite electrode e.g. 30 of which are piled to form an electrolysis appts. for prodn. of H2 and Cl2 from HCl provides gaps to allow frame shrinkage so that strain does not result in fissuring and life is extended beyond usual 6-12 months. Frame and electrode are held together by adhesive or bolting, and a groove may be provided in frame to guide knife used in cutting away to release electrode for renewal. Seal is formed by a flexible gasket e.g. of PTFE.

Als elastische Dichtung kann dabei ein O-Ring in einer Nut, eine Schnur oder eine Flachdichtung aus chlorsulfoniertem Polyäthylen, Polytetrafluoräthylen, Fluorkarbonkautschuk oder Asbest verwendet werden.An O-ring in a groove, a cord or a flat gasket made of chlorosulfonated polyethylene, Polytetrafluoroethylene, fluorocarbon rubber or asbestos be used.

Geeignete lösbare Verbindungselemente sind dabei Sicherungsstäbe, Halteplatten oder Schrauben aus asbestverstärktem Kresolformaldehydharz, GFK, PP oder nachchloriertem PVC.Suitable detachable connecting elements are safety bars, Retaining plates or screws made of asbestos-reinforced cresol formaldehyde resin, GRP, PP or post-chlorinated PVC.

Durch die HCl-Elektrolyserahmen mit eingelegter Graphitplatte nach dem Patent (P 23 17 359-3) werden Rissbildungen im Elektrolyserahmen verhindert.Through the HCl electrolysis frame with an inserted graphite plate According to the patent (P 23 17 359-3) cracks in the electrolysis frame are prevented.

Eine besonders vorteilhafte' Ausführungsform der HCl-Elektrolyserahmen mit eingelegter Graphitplatte und elastischen Dichtungen zwischen der Graphitplatte und dem Elektrolyserahmen sowie lösbaren Verbindungselementen zwischen dem ElektrolyserahmenA particularly advantageous' embodiment of the HCl electrolysis frame with inserted graphite plate and elastic seals between the graphite plate and the electrolysis frame as well detachable connecting elements between the electrolysis frame

Graphitplatte (2) aus dem Elektrolyserahmen (1) dienen.Graphite plate (2) from the electrolysis frame (1) are used.

Die Eittangüsse (6, 7 und 8) an der Graphitplatte (2) und am Elektrolyserahmen (1) können dabei aus Phenolformaldehydharz oder Kresolformaldehydharz bestehen.The Eittanguss (6, 7 and 8) on the graphite plate (2) and on Electrolysis frames (1) can consist of phenol formaldehyde resin or cresol formaldehyde resin.

Für die Ausschalungen (4 und 5) kann Polyvinylchlorid, Polyäthylen oder Polypropylen verwendet werden.Polyvinyl chloride, polyethylene can be used for the shuttering (4 and 5) or polypropylene can be used.

Nach dem Aushärten der Angüsse werden die umlaufenden PVG-, PE- oder PP-Leisten (5) entfernt, so daß zwischen Graphitplatte (2) und Elektrolyserahmen (1) ein Spalt von der Breite der herausgenommenen Leisten vorhanden ist. Eine Bewegung des Elektrolyserahmens zur Graphitplatte ist somit gewährleistet.After the sprues have hardened, the surrounding PVG, PE or PP strips (5) are removed so that between the graphite plate (2) and electrolysis frame (1) there is a gap the width of the removed strips. A movement of the Electrolysis frame to the graphite plate is thus guaranteed.

Um die untere Dichtung zu entlasten, stützt sich im Betriebszustand die Graphitplatte (2) auf dem Elektrolyserahmen (1) ab, während bei den beiden gegenüberliegenden Seiten ein Spiel zwischen Graphitplatte und Elektrolyserahmen vorhanden ist.In order to relieve the lower seal, it is supported in the operating state the graphite plate (2) on the electrolysis frame (1), while a game on the two opposite sides is present between the graphite plate and the electrolysis frame.

Die Arretierung der Graphitplatte an der Oberseite erfolgt1ebenfalls durch die beschriebenen Angüss'e, jedoch wird hier eine Verbindung der Angüsse (7 und 8) zur Graphitplatte hergestellt.The locking of the graphite plate on the top side also is performed by the 1 Angüss'e described, however, a connection of the gates (7 and 8) prepared for graphite plate here.

Die Erfindung ermöglicht eine leichte Demontage der Graphitplatte. Durch eine Präsvorrichtung, die in einer am Elektrolyserahmen (1) umlaufenden·Nut (9) geführt wird, können die Angüsse abgefräst werden, so daß die Graphitplatte aus dem Elektrolyserahmen leicht herausgenommen werden kann.The invention enables easy dismantling of the graphite plate. The Sprues are milled off so that the graphite plate can be easily removed from the electrolysis frame.
