Definitions

  • the invention relates to a working electrode for an electrodynamic fragmentation system, change parts for such a working electrode and a use of the working electrode according to the preambles of the independent claims.
  • high voltage breakdowns are produced by a working electrode applied to high voltage pulses and a base electrode, which is usually at a neutral potential, through the material to be comminuted, which leads to the comminution of the material.
  • a slight removal of material at the working electrode tip takes place at each high-voltage breakdown, so that it is worn after a certain period of use and must be replaced. It may also be necessary to change the electrode when changing the material to be digested with the equipment in order to prevent contamination of the end product with unwanted electrode material.
  • high-voltage electrodes are known from the prior art in which the electrode tip is formed by an exchangeable exchangeable part and which thereby largely avoid the aforementioned disadvantages.
  • Such high voltage electrodes are for example in SU 1790069 A1 . SU 1781892 A1 . JP 2003 001137 A and US 2005/0150668 A1 shown.
  • these high-voltage electrodes have the disadvantage that, in the case of strong pressure pulsations in the working space, the alternating part forming the electrode tip can come loose, which is why such high-voltage electrodes are relatively maintenance-intensive.
  • a first aspect of the invention relates to a working electrode for an electrodynamic fragmentation system with a replaceable electrode tip.
  • the working electrode comprises an insulator body, for example of plastic or of a ceramic material, with a central conductor of a highly electrically conductive, preferably metallic material, for example of aluminum, copper or stainless steel, which passes through the insulator axially.
  • a high voltage generator for charging the working electrode with high voltage pulses.

  • Such working electrodes with structurally provided Dehn Siemensen are robust and can be operated maintenance-free over a long time even with strong pressure pulsations in the working space, as between the central conductor and the removable removable part only Schwell procedure occur, but not alternating forces. They also have the advantage that when the electrode is worn or when the material to be comminuted, only the electrode tip has to be exchanged and, for example, an opening of an oil-filled high-voltage system for the replacement of the entire working electrode becomes superfluous. As a result, the maintenance-related downtime and operating costs of electrodynamic fragmentation systems can be significantly reduced.
