Definitions

  • the present invention relates to a process for clamping and tightening diaphragms in filter press type cells for the electrolysis of aqueous hydrochloric acid.
  • the anode chambers are separated from the cathode chambers by diaphragms made of fabrics that are resistant to chlorine. These fabrics are clamped between the electrode frames by means of elastic packings. The packings simultaneously serve to seal the electrolysis chambers and to fasten the diaphragms along their rims.
  • the packing is designed as a frame of soft rubber which is pressed between the electrode frames.
  • the diaphragm is inserted into a slot of the packing and secured by bonding or sewing.
  • One side of each of the frames of the bipolar electrodes is provided with pins serving for the fixation of the packing frame.
  • the soft rubber packing is resistant to chlorine to a limited extent only. There is a danger that the sewn or bonded seams gradually become pervious, so that chlorine and hydrogen may mix with one another.
  • Other packing materials for example, polytetrafiuoroethylene, cannot be used in the above-described form for technical and economical reasons.
  • the packing frame is a complicated profilated piece which is consequently very expensive and which after a diaphragm has been exchanged can no longer be used. Moreover, it is diflicult to adapt the suspension eyes of the packing frame exactly to the dimensions of, and the distances between, the pins arranged on the electrode frame.
  • the packing is advantageously made of an appropriate elastic material that is resistant to chemical substances, for example, rubber, impregnated asbestos or asbestos coated with polytetrafiuoroethylene or soft polyvinyl chloride.
  • the packing is used in the form of an endless cord. Its cross-section is of little importance and may be, for example, quadrangular, trapezoidal or round.
  • an electrode frame 1 is provided on one side with a groove 2 into which a diaphragm 3 is inserted.
  • the diaphragm is fixed by means of a V- ledge 4. If any material of the diaphragm should project at A it is removed.
  • An endless packing 5 is then inserted and pressed firmly against neighbouring electrode 1a. Owing to this operation the packing is pressed against electrode 1 between A and B and against electrode in between C and D and makes the electrode chambers tight to gases and liquids.
  • a process for clamping and tightening diaphragms in filter press type cells for the electrolysis of aqueous hydrochloric acid which comprises inserting the diaphragm into a groove of the electrode frame and clamping it with a V-ledge, then inserting an endless packing cord into the groove and pressing it against the frame of the neighbouring electrode.
