A device for regenerating the cooling emulsion (3) stagnating in the tanks (2) of the machine tools, characterized in that the proliferation of anaerobic bacteria responsible for the evil-smelling deterioration of said emulsion (3) is suppressed by the use of a plurality of oxygenation pipes (1) submersed in the cooling liquid and capable of producing air microbubbles that ensure a sufficient and uniform oxygenation of the emulsion and avoid the formation of the typical, continuous lubricating oil layer above the coolant (3). Said oxygenating microbubbles causes also a continuous displacement of the cooling emulsion (3) that reduce the risk of dissociation of the emulsion itself.
L'invention concerne un dispositif permettant de stabiliser l'émulsion réfrigérante (3) qui se forme et stagne au fond des réservoirs (2) de machines-outils, ce dispositif permettant notamment d'empêcher la prolifération des bactéries anaérobies responsables de la dégradation malodorante de ladite émulsion (3), et ce par une oxygénation de celle-ci effectuée au moyen d'une pluralité de tubes (1) immergés dans le liquide réfrigérant. Ces tubes sont destinés à diffuser des microbulles d'air qui garantissent une oxygénation suffisante et uniforme de l'émulsion, et qui évitent la formation de la couche d'huile lubrifiante continue se formant habituellement au-dessus du réfrigérant (3). De plus, cette diffusion de microbulles oxygénantes provoque un déplacement continu de ladite émulsion réfrigérante (3), ce qui réduit les risques de dissociation de cette émulsion.
