Abstract

A separator attachment for use with a vibratory apparatus, the attachment including a housing mountable to a vibratory apparatus below a material-conveying surface of the vibratory apparatus, the housing defining a pressure chamber with an inlet and an outlet. The housing has at least one wall with a wall surface having a first end disposed proximate to the outlet of the pressure chamber and a second end. The attachment also includes a deflector plate with a deflector plate surface having a first end disposed proximate to the outlet of the pressure chamber and a second end, the deflector plate surface facing the wall surface. The deflector plate is translatable relative to the at least one wall to vary the spacing between the deflector plate surface and the wall surface. A system including a vibratory apparatus and the attachment may also be defined.

Claims

1. A separator attachment for use with a vibratory apparatus, the attachment comprising:

a housing adapted to be attached to and detached from a vibratory apparatus below a material-conveying surface of the vibratory apparatus, the housing defining a pressure chamber with an inlet and an outlet,

the housing having at least one wall with a wall surface having a first end disposed proximate to the outlet of the pressure chamber and a second end; and

a deflector plate with a deflector plate surface having a first end disposed proximate to the outlet of the pressure chamber and a second end, the deflector plate surface facing the wall surface and spaced from the wall surface to define an air passage therebetween,

the deflector plate translatable relative to the at least one wall between a first position, wherein the deflector plate is translated nearer to the at least one wall so that the first ends and second ends of the deflector plate surface and the wall surface to define a first width for the air passage therebetween, and a second position, wherein the deflector plate is translated farther away from the at least one wall so that the first ends and second ends of the deflector plate surface and the wall surface to define a second width for the air passage therebetween, the second width being different than the first width.

2. The separator attachment of claim 1, wherein the wall surface and the deflector plate surface are planar and parallel to each other.

3. The separator attachment of claim 2, wherein the wall surface and the deflector plate surface are disposed at an angle relative to the horizontal.

4. The separator attachment of claim 1, the deflector plate being translatable relative to the at least one wall along a line of motion, the deflector plate having end plates each with an elongated slot, the slots being parallel to the line of motion of the deflector plate.

5. The separator attachment of claim 4, comprising fasteners received in the slots in the end plates of the deflector plate to attach the deflector plate to the housing.

6. The separator attachment of claim 1, comprising a perforated plate disposed at the outlet of the pressure chamber.

16. The separator attachment of claim 1, wherein the at least one wall defines in part the pressure chamber.

7. A system comprising:

a vibratory apparatus including (i) a material-conveying surface with an inlet end and an outlet end, (ii) a plurality of resilient members supporting the material-conveying surface, and (iii) a vibration generator coupled to the material-conveying surface to move material along the material-conveying surface from the inlet end to the outlet end; and

a separator attachment adapted to be attached to and detached from the vibratory apparatus, the separator attachment comprising (i) a housing detachably coupled below the material-conveying surface at the outlet end, the housing defining a pressure chamber with an inlet, an outlet and at least one wall with a wall surface having a first end disposed proximate to the outlet of the pressure chamber and a second end, and (ii) a deflector plate with a deflector plate surface having a first end disposed proximate to the outlet of the pressure chamber and a second end, the deflector plate surface facing the wall surface and spaced from the wall surface to define an air passage therebetween, the deflector plate translatable relative to the at least one wall between a first position, wherein the deflector plate is translated nearer to the at least one wall so that the first ends and second ends of the deflector plate surface and the wall surface to define a first width for the air passage therebetween, and a second position, wherein the deflector plate is translated farther away from the at least one wall so that the first ends and second ends of the deflector plate surface and the wall surface to define a second width for the air passage therebetween, the second width being different than the first width.

8. The system of claim 7, wherein the wall surface and the deflector plate surface are planar and parallel to each other.

9. The system of claim 8, wherein the wall surface and the deflector plate surface are disposed at an angle relative to the horizontal.

10. The system of claim 7, the deflector plate being translatable relative to the at least one wall along a line of motion, the deflector plate having end plates each with an elongated slot, the slots being parallel to the line of motion of the deflector plate.

11. The system of claim 10, comprising fasteners received in the slots in the end plates of the deflector plate to attach the deflector plate to the housing.

12. The system of claim 7, wherein the at least one wall defines in part the pressure chamber.

13. The system of claim 7, comprising a perforated plate disposed at the outlet of the pressure chamber.

14. The system of claim 7, wherein the vibratory apparatus is a vibratory conveyor.

15. The system of claim 7, wherein the vibratory apparatus is a vibratory classifier.
