Apparatus and process for concentrating a separable component of a slurry

1. An apparatus comprising

at least one vessel having an opening and an inlet, such that the opening is spaced from the inlet along a length of the at least one vessel;

a supplier operable to supply a slurry mixture through the inlet and into the at least one vessel, wherein the at least one vessel comprises a plurality of perforations dimensioned to receive a liquid flow from the slurry mixture to dry the slurry mixture;

a vibrator for imparting vibrations to the at least one vessel, the vibrator being attached to the at least one vessel; and

an extractor operable to extract the dried slurry mixture from the opening.

2. The apparatus as defined in claim 1 wherein

the at least one vessel comprises an inner vessel and an outer vessel,

the inner vessel comprises the opening and the inlet,

the outer vessel is attached to and adjoins at least a portion of the inner vessel, and

the portion of the inner vessel adjoining the outer vessel comprises the plurality of perforations dimensioned to provide the liquid flow from the slurry mixture within the inner vessel to a volume outside the inner vessel and enclosed by the outer vessel.

3. The apparatus as defined in claim 1 wherein the inner vessel and the outer vessel are substantially vertically oriented such that the opening is substantially above the inlet.

4. The apparatus as defined in claim 3 wherein the plurality of perforations are a plurality of slits.

5. The apparatus as defined in claim 3 wherein the plurality of perforations vary in size along the length of the inner vessel.

6. The apparatus as defined in claim 5 wherein the plurality of perforations are larger toward the opening and are smaller toward the inlet.

7. The apparatus as defined in claim 4 wherein each perforation in the plurality of perforations has a perforation width of between 0.005 inches and 0.06 inches and a perforation length of between 0.005 inches and 5 inches.

8. The apparatus as defined in claim 2 wherein the outer vessel is attached to the inner vessel by a plurality of mounts, each mount having a curved or inclined upward facing surface to impede ice buildup on the curved or inclined upward facing surface.

9. The apparatus as defined in claim 1 wherein the extractor comprises an auger extending into the at least one vessel via the opening, and an auger driver for driving the auger to extract the dried slurry mixture from the opening.

10. The apparatus as defined in claim 1 wherein the vibrator is adjustably attached to the at least one vessel such that the vibrator can be moved along the length of the at least one vessel.

11. The apparatus as defined in claim 1 wherein the vibrator comprises a frequency controller configured to control and adjust a frequency of the vibrator.

12. A method comprising:

providing a slurry mixture comprising a material in a melted liquid form and in a solid frozen form;

forcing the slurry mixture through an inlet into a vessel and through the vessel to an opening, wherein the vessel comprises a plurality of perforations dimensioned to receive a liquid flow from the slurry mixture to dry the slurry mixture;

vibrating the vessel and the slurry mixture within the vessel to shake the material in the melted liquid form out through the plurality of perforations to dry the slurry mixture; and,

extracting the dried slurry mixture from the opening.

13. The method as defined in claim 12 further comprising, before forcing the slurry mixture through the inlet into the vessel, orienting the vessel such that the opening is substantially above the inlet.

14. The method as defined in claim 12 further comprising adjusting a frequency for vibrating the vessel when the slurry mixture is being forced through the vessel.

15. The method as defined in claim 12 wherein vibrating the vessel and the slurry mixture within the vessel comprises attaching a vibrator to the vessel at a selected point, and the method further comprises adjusting a location of the selected point along a length of the vessel to change the location where vibration is imparted to the vessel and the slurry mixture within the vessel.
