  • the separating plate is removed, so that the sieve box can then easily be lifted upwards in the manner described above.
  • the slotted screen can expediently be locked in its assembled working position.
  • a very particularly advantageous embodiment results if the separating plate with its lower edge is in the assembled working position of the screen box into a locking groove arranged on the top of the sieve box and thus fulfills a double function by not only sealing off the collection container from the service container, but also ensuring that the sieve box is locked in its working position in the correct position.

Abstract

La présente invention concerne un dispositif (10) permettant la séparation et l'extraction de copeaux et de liquide de travail d'une réservoir collecteur (11) associé à une machine d'usinage par enlèvement de copeaux. Ledit dispositif présente un tamis (20) doté d'un élément filtrant (23) et disposé dans le réservoir en étant plongé dans le liquide de travail, et un système d'acheminement de copeaux (14) grâce auquel les copeaux peuvent être acheminés jusqu'à une zone d'évacuation située au dessus du niveau du liquide. Pour permettre un échange plus rapide du tamis, un réservoir auxiliaire (26) est mis en place latéralement contre le système d'acheminement de copeaux, une zone de raccordement (27) du tamis qui fait saillie latéralement au dessus du système d'acheminement de copeaux, dépassant dans ledit réservoir auxiliaire, la zone de raccordement présentant au niveau de son côté supérieur un élément de raccordement rapide (29) destiné au tube plongeur d'une pompe submersible ou à un tuyau d'aspiration de filtrat (30). Le tamis peut ainsi, après un démontage rapide du tuyau d'aspiration de filtrat, être soulevé et extrait par le dessus du réservoir auxiliaire, sans impliquer à cet effet le vidage du liquide de travail du réservoir collecteur ou le démontage du système d'acheminement de copeaux.
