Abstract

An example nonlimiting embodiment of the present invention provides a flow divider that includes a slurry receiving compartment and a discharge arrangement having a plurality of discharge apertures. The slurry receiving compartment is arranged to relatively uniformly flow a portion of a slurry into each of the discharge apertures. The discharge apertures may be arranged linearly and/or horizontally such that the portions of the slurry exits each of the discharge apertures at a relatively even flow rate and feed feed boxes connected to vertically tiered screening surfaces of a screening machine.

First claim

What is claimed is:

1. A flow divider, comprising:
a top opening;
a plurality of discharge apertures;
a slurry inlet located below the plurality of discharge apertures;
a plurality of separator plates configured to divide a flow of a slurry and direct a substantially equal flow of slurry to each of the plurality of discharge apertures;
a slurry receiving compartment;
a slurry discharge compartment; and
a flow plate,
wherein the flow divider is configured to receive the slurry from either the top opening or from the slurry inlet and to divide the flow of the slurry to thereby provide a substantially equal flow of slurry out of each of the plurality of discharge apertures,
wherein the flow plate separates the slurry receiving compartment from the slurry discharge compartment,
wherein the plurality of separator plates divide the slurry discharge compartment into a plurality of discharge sub-compartments, each sub-compartment including a feed pocket that is configured to feed slurry to a corresponding discharge aperture.

2. The flow divider of claim 1 , further comprising a cap that is configured to close the slurry inlet to prevent flow of slurry through the slurry inlet,
wherein the flow divider is configured to receive the slurry from the top opening.

3. The flow divider of claim 1 , further comprising a cover configured to cover the top opening,
wherein the flow divider is configured to receive the slurry from the slurry inlet.

4. The flow divider of claim 3 , further comprising tubing configured to connect the slurry inlet to an external pump that is configured to pump slurry into the flow divider through the slurry inlet.

5. The flow divider of claim 4 , wherein, upon receiving a flow of slurry from the slurry inlet, the flow divider is configured to direct a flow of slurry upwardly from the slurry inlet to each of the plurality of discharge apertures.

6. The flow divider of claim 1 , wherein each feed pocket further comprises a bottom portion that forms a weir, wherein the weirs of the sub-compartments are configured to allow slurry to flow relatively simultaneously into respective sub-compartments.

7. A system, comprising:
a screening machine having a plurality of stacked screening units and a plurality of feeder boxes; and
a flow divider located above the screening machine and having members that are configured to uniformly divide a slurry into portions that flow from the flow divider to the plurality of feeder boxes, the flow divider comprising:
a top opening;
a plurality of discharge apertures;
a slurry inlet located below the plurality of discharge apertures;
a plurality of separator plates configured to divide a flow of slurry and direct a substantially equal flow of slurry to each of the plurality of discharge apertures;
a slurry receiving compartment;
a slurry discharge compartment; and
a flow plate,
wherein the flow divider is configured to receive the slurry from either the top opening or from the slurry inlet and to provide the substantially equal flow of slurry out of each of the plurality of discharge apertures,
wherein the flow plate separates the slurry receiving compartment from the slurry discharge compartment, and
wherein the plurality of separator plates divide the slurry discharge compartment into a plurality of discharge sub-compartments, each sub-compartment including a feed pocket that is configured to feed slurry to a corresponding discharge aperture.

8. The system of claim 7 , wherein the flow divider further comprises a cap that is configured to close the slurry inlet to prevent flow of slurry through the slurry inlet,
wherein the flow divider is configured to receive slurry from the top opening.

9. The system of claim 7 , wherein the flow divider further comprises a cover configured to cover the top opening,
wherein the flow divider is configured to receive slurry from the slurry inlet.

10. The system of claim 9 , wherein the flow divider further comprises tubing configured to connect the slurry inlet to an external pump that is configured to pump slurry into the flow divider through the slurry inlet.

11. The system of claim 10 , wherein, upon receiving a flow of slurry from the slurry inlet, the flow divider is configured to direct a flow of slurry upwardly from the slurry inlet to each of the plurality of discharge apertures.

12. The system of claim 7 , wherein each feed pocket of the flow divider further comprises a bottom portion that forms a weir, wherein the weirs of the sub-compartments are configured to allow slurry to flow relatively simultaneously into respective sub-compartments.

13. A method, comprising:
receiving a slurry into a flow divider having:
a top opening,
a plurality of discharge apertures,
a slurry inlet located below the plurality of discharge apertures,
a slurry receiving compartment;
a slurry discharge compartment;
a plurality of separator plates, wherein the plurality of separator plates divide the slurry discharge compartment into a plurality of discharge sub-compartments, each sub-compartment including a feed pocket that is configured to feed slurry to a corresponding discharge aperture; and
a flow plate, wherein the flow plate separates the slurry receiving compartment from the slurry discharge compartment; and

dividing the flow to thereby discharge a portion of the slurry substantially evenly from each of the individual discharge apertures,
wherein receiving the slurring further comprises receiving the slurry from either the top opening or from the slurry inlet.

14. The method of claim 13 , further comprising:
closing the slurry inlet to prevent flow of slurry through the slurry inlet; and
receiving the slurry from the top opening.

15. The method of claim 13 , further comprising:
closing the top opening with a cover; and
receiving the slurry from the slurry inlet.

16. The method of claim 15 , further comprising:
causing an external pump to pump slurry into the flow divider through the slurry inlet; and
directing a flow of the received slurry upwardly from the slurry inlet to each of the plurality of discharge apertures.
