Definitions

  • the present invention relates to a device for cleaning fluids such as cutting fluids, washing fluids or other fluids, from e.g. oil leaks, such as lubricants or other impurities.
  • Cutting fluids are used for cooling and lubrication during milling, drilling and other types of machining.
  • lubricant or the like, and other impurities often leak into the cutting fluid, gradually contaminating it and making it unusable.
  • a simple and efficient device is sought to allow separation of these impurities from the cutting fluid so that this can be used again, i.e. re-circulated in the machining process.
  • Oils leaking in may be lubricants, hydraulic oils, slide grease, etc. Similar problems often exist for other fluids, such as fluids for washing where it is also desirable to be able to get ⁇ d of impurities in a simple manner.
  • the invention aims at a solution to these and other similar problems. It is characterized in that it comprises a float for application in the fluid to be cleaned, e.g. a cutting-fluid vessel, said float consisting of a container with an upper part of a type that will float on inner and outer fluids, e.g. with lower density than these fluids or with the aid of an air pocket, thereby constituting a floating body which floats on the surface fluid entering through an inlet at the top of the container, side walls and a bottom, together forming a container with an inlet at the top and a conduit leading from the container to a pump for pumping off surface fluid that has entered the container.

  • the float thus has an upper part in the form of a floating body which floats on the surface fluid that has entered the container.
  • the float floats on the fluid and the impurities are deposited in a thin layer on top of this, such as oil on top of cutting fluid.
  • the upper part floats at the same level as the surrounding fluid, but when it is in operation the upper part will sink slightly below the surface of the fluid and impurities enter the container through this upper inlet.
  • the float consists of a bellows and an upper part as described above, the bellows being connected to the bottom.
  • the side walls are flexible or inflexible, and movable in relation to a bottom arranged inside the walls, with a space to the side walls in the form of a narrow gap. This enables relative movement between side walls and bottom.

  • This upper part floats on fluid (15) which has entered the container when cleaning cutting fluid, for instance.
  • Cutting fluid is used in various machining processes such as milling, drilling, etc. and various oils, such as lubricants, hydraulic oil, slide grease, are also used for these processes.
  • Other impurities, such as metal shavings, dust, etc. may also result from the machining process and may leak into the cutting fluid together with the lubricant and contaminate it after a while. Such impurities for the most part float on top of the cutting fluid.

  • the bottom (9) fits the walls with a certain clearance (10) and, as in the previous case, an upper part (2) is provided, having a density lower than both the inner and outer fluid. Pumping off is effected via the conduit (6, 7).

Abstract

La présente invention concerne un dispositif de purification de fluides tels que des fluides de coupe, de lavage ou d'autres fluides, destiné à enlever de ceux-ci des fuites d'huile, telles que des lubrifiants ou d'autres impuretés. L'invention est caractérisée en ce qu'elle comprend un flotteur destiné à être placé dans le fluide à nettoyer, par exemple, dans une cuve de fluide de coupe, ce flotteur se composant d'un contenant (1) pourvu d'une partie supérieure (2) d'un type qui flotte sur les fluides intérieurs et extérieurs, par exemple d'un type possédant une densité inférieure à ces fluides, ou grâce à une poche d'air, constituant ainsi un corps flottant sur le fluide de surface entrant à travers un orifice d'entrée (5) situé au sommet du contenant; ce contenant est également pourvu de parois latérales (3) ainsi que d'un fond (4), lesquels forment avec la partie supérieure un contenant présentant un orifice d'entrée (5) au niveau de son sommet et un conduit (6, 7) menant du contenant (1) à une pompe destinée à aspirer par pompage le fluide de surface ayant pénétré dans le contenant.
