Definitions

  • the invention relates to a separating device for separating grinding media and ground suspension in a wet grinding machine, with a sieve arranged at the grinding material outlet of the wet grinding machine, the passage openings of which are designed with dimensions that block the passage of grinding media.
  • the invention is therefore based on the object of providing a separating device in the case of clogged sieves can be cleaned quickly and properly during operation of the wet shredder.
  • the outlet surface of the screen is arranged opposite a movable plate in the direction of the screen and the plate is provided on the side facing the screen with elements for piercing the openings of the screen, the elements being aligned with the openings of the sieve are arranged.
  • the plate can be moved manually, pneumatically, hydraulically or electrically using a linkage. If the screen is designed as a slotted screen, the elements of the plate opposite the slotted screen are designed as sheet metal strips.
  • the drawing shows a section through the grinding chamber and through the slotted screen of an agitator mill, as well as through the plate arranged opposite the slotted screen with the narrow, solid sheet metal strips incorporated therein.
  • ground suspension and grinding media 2 in the interior of a grinding chamber 1 of an agitator mill.
  • the ground suspension leaves the grinding chamber via the grinding material outlet opening 3.
  • a flat sieve 4 designed as a slotted sieve is arranged, the gap widths of which are approximately 1/3 of the grinding element diameter.
  • the grinding media 2 and the suspension leaving the grinding chamber 1 are separated and at the same time the grinding media 2 are retained.
  • Small particles that are about the same size as the gap widths of the flat screen and consist of abraded and broken grinding media and product particles can get stuck in the flat screen and thereby reduce the free screen area. Often this has the consequence that the flat screen is already after clogged for a few hours.
  • a plate 5 which is movable in the direction of the flat screen is arranged opposite the exit surface thereof. Narrow, fixed sheet metal strips 6 are embedded in this plate, which are aligned with the openings 7 of the flat screen 4. In the event of a possible blockage, the metal strips are pushed through the openings 7 of the flat screen. As a result, the sieve-clogging particles are returned to the grinding chamber and the free sieve area is increased.
  • the plate 5 is moved by means of a linkage 8.
  • a seal 9 prevents suspension from flowing to the outside via the rod outlet opening. If the flat screen is clogged again, the process described above can be repeated periodically as required.
  • the movable plate is made of metal and the sheet metal strips are connected to the plate by welding.
  • the thickness of the metal strips is slightly less than the openings of the flat screen.
  • the dimension "b" of the sheet metal strips is greater than the thickness "k" of the flat screen.
  • the sieve can be designed as a perforated plate and the metal strips in the movable plate as mandrels.
  • the advantages achieved with the invention consist in particular in that the cleaning of the slotted screen can be carried out quickly and correctly from the outside during operation. This eliminates the need for time-consuming cleaning work on the slotted screen and the service life of the wet shredders is significantly increased.
