Abstract

Oil and aqueous phase separator device comprising: a basket that comprises a frame having a plurality of supporting arms and fitting means for linking to other phase separator devices; a top lid of the basket; a hydrophobic mesh linked to the basket and supported by the plurality of supporting arms; a plurality of floats linked to the frame of the basket; a housing for an additional float formed on the upper edge of the frame of the basket; and discharging means linked to the basket.

First claim

The invention claimed is:

1. An oil and aqueous phase separator device, comprising:
a basket comprising a frame having an upper edge defining an upper opening in the basket, the frame comprising a plurality of supporting arms and fitting means for linking to other phase separator devices;
a lid that closes the upper opening of the basket;
an hydrophobic mesh inked to the basket and supported by the plurality of supporting arms;
a plurality of floats connected to the frame of the basket;
a housing for an additional float formed on the upper edge of the frame of the basket;
a discharging means linked to the basket.

2. The device according to claim 1 , wherein the lid that closes the upper opening and the frame of the basket comprise a horizontal cross section similarly or equally shaped as a polygon.

3. The device according to claim 2 , wherein the plurality of supporting arms comprises a supporting arm at each vertex of the polygon.

4. The device according to claim 3 , wherein each supporting arm is slightly downwardly curved forming a concavity with respect to the lid, the supporting arms joining together at the central axis of the device.

5. The device according to claim 4 , wherein each supporting arm has an internal grooved channel.

6. The device according to claim 4 , wherein the discharging means is located at the central axis of the device, where the supporting arms join together.

7. The device according to claim 3 , wherein at least one of the supporting arms comprises a fin-shaped protrusion on its lower surface.

8. The device according to claim 2 , wherein at least one of the polygon vertices formed by the frame comprises a float.

9. The device according to claim 8 , wherein each one of the plurality of floats comprises a curved body with upper and lower horizontal surfaces.

10. The device according to claim 8 , wherein each one of the plurality of floats comprises a downwardly tilted body towards the central axis of the device.

11. The device according to claim 1 , wherein the lid that closes the upper opening has an outer convex surface.

12. The device according to claim 1 , wherein the lid that closes the upper opening comprises, on the outer surface, a plurality of protrusions.

13. The device according to claim 1 , wherein the hydrophobic mesh comprises a metallic mesh coated with an hydrophobic substance.

14. The device according to claim 13 , wherein the hydrophobic substance comprises compounds with hydrocarbon chains selected from the group comprising silicones, polyolefins and fluoropolymers.

15. The device according to claim 1 , wherein the plurality of supporting arms supports the hydrophobic mesh in a suitable way and position to form an oil phase receiving concavity.

16. The device according to claim 1 , wherein the fitting means comprise male connectors and female connectors located each other in an alternate pattern in every one of outer lateral surfaces of the frame of the basket.

17. The device according to claim 16 , wherein the male connector consists of a protrusion shaped as a solid cylinder and the female connector consists of a protrusion shaped as a hollow cylinder with a lengthwise opening, so as to form a hook.

18. The device according to claim 16 , wherein the male connector consists of a protrusion with substantially spheroidal shape and the female connector consists of a cavity to hold said protrusion.

19. The device according to claim 1 , wherein the floats are connected to the basket by means of a mechanical coupling or adhesives resistant to the oil phase and to the aqueous phase.

20. The device according to claim 1 , wherein the phase separator device is linked to other similar or equal phase separator devices, by means of the fitting means, so as to form a plurality of phase separator devices linked together, where said plurality may comprise a number of 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 or more phase separator devices.
