Abstract

A dual waterfall cabinet includes a hollow basin having front and rear openings to allow workpieces to move therethrough. The cabinet also includes waterfall assemblies on either side of the hollow basin that form waterfalls of solution to be applied to the workpieces. To provide thorough interior and exterior coverage, the distance between the waterfalls can vary along a length of the cabinet.

Claims (47)

1 . An apparatus comprising:

a hollow basin comprising first and second sidewalls opposite one another, a front end having an opening therethrough, and a rear end having an opening therethrough;

a first waterfall assembly affixed to the first sidewall, wherein the first waterfall assembly comprises a first trough extending substantially from the front end to the rear end;

a second waterfall assembly affixed to the second sidewall, wherein the second waterfall assembly comprises a second trough extending substantially from the front end to the rear end;

a first supply line configured to supply a solution to the first waterfall assembly such that the solution spills from the first trough into the hollow basin; and

a second supply line configured to supply the solution to the second waterfall assembly such that the solution spills from the second trough into the hollow basin;

wherein the solution comprises an antimicrobial agent and/or a pH adjuster.

2 . The apparatus of claim 1 , further comprising a drain positioned within the hollow basin and configured to collect at least a portion of the solution from the first and second troughs.

3 . The apparatus of claim 1 , further comprising a first meter positioned along the first supply line and configured to measure a first flow rate of solution through the first supply line and/or a second meter positioned along the second supply line and configured to measure a second flow rate of solution through the second supply line.

4 . The apparatus of claim 3 , further comprising a control panel in communication with the first meter and/or the second meter, wherein the control panel is configured to control the first flow rate and/or the second flow rate.

5 . The apparatus of claim 1 , further comprising a first front bracket and a second front bracket affixed to the front end of the hollow basin and a first rear bracket and a second rear bracket affixed to the rear end of the hollow basin;

wherein the first waterfall assembly comprises a first front waterfall bracket configured to be adjustably affixed to the first front bracket and a first rear waterfall bracket configured to be adjustably affixed to the first rear bracket; and

wherein the second waterfall assembly comprises a second front waterfall bracket configured to be adjustably affixed to the second front bracket and a second rear waterfall bracket configured to be adjustably affixed to the second rear bracket.

6 . The apparatus of claim 5 , wherein an angle between the first waterfall assembly and the second waterfall assembly is adjustable between 0 and 60 degrees.

7 . The apparatus of claim 1 , wherein a distance between the first waterfall assembly and the second waterfall assembly at the front end is less than a distance between the first waterfall assembly and the second waterfall assembly at the rear end.

8 . The apparatus of claim 1 , wherein the apparatus is configured to be suspended off of the ground.

9 . A system comprising:

a waterfall cabinet comprising:

a hollow basin comprising first and second sidewalls opposite one another, a front end having an opening therethrough, and a rear end having an opening therethrough;

a first waterfall assembly affixed to the first sidewall, wherein the first waterfall assembly comprises a first trough extending substantially from the front end to the rear end;

a second waterfall assembly affixed to the second sidewall, wherein the second waterfall assembly comprises a second trough extending substantially from the front end to the rear end;

a first supply line configured to supply solution to the first waterfall assembly such that solution spills from the first trough into the hollow basin; and

a second supply line configured to supply the solution to the second waterfall assembly such that the solution spills from the second trough into the hollow basin;

a solution supply comprising the solution and configured to supply the solution to the first and second supply lines; and

a shackle line configured to suspend workpieces therefrom;

wherein the solution comprises an antimicrobial agent and/or a pH adjuster;

wherein the waterfall cabinet is suspended about the shackle line; and

wherein the shackle line is configured to move the workpieces through the openings of the front and rear ends of the hollow basin.

10 . The system of claim 9 , wherein the hollow basin comprises a drain positioned within the hollow basin and configured to collect at least a portion of the solution from the first and second troughs.

11 . The system of claim 10 , further comprising a recycling unit configured to recycle the solution from the drain back to the first and second waterfall assemblies.

12 . The system of claim 11 , wherein the recycling unit is configured to remove solid materials from the solution.

13 . The system of claim 9 , wherein the waterfall cabinet is suspended from 1 to 30 feet off of the ground.

14 . The system of claim 9 , wherein the waterfall cabinet is positioned about the shackle line such that the first and second troughs are from 0 to 8 inches above the workpieces.

15 . The system of claim 14 , wherein the first and second troughs are from 4 to 6 inches above the workpieces.

16 . The system of claim 9 , wherein the solution is supplied at a rate of 10 to 30 gallons per minute to each of the first supply line and the second supply line.

17 . A method of applying a solution to workpieces, comprising:

suspending workpieces from a shackle line;

suspending a waterfall cabinet about the shackle line, wherein the waterfall cabinet comprises:

a hollow basin comprising first and second sidewalls opposite one another, a front end having an opening therethrough, and a rear end having an opening therethrough;

a first waterfall assembly affixed to the first sidewall, wherein the first waterfall assembly comprises a first trough extending substantially from the front end to the rear end;

a second waterfall assembly affixed to the second sidewall, wherein the second waterfall assembly comprises a second trough extending substantially from the front end to the rear end;

supplying the solution to the first and second waterfall assemblies such that the solution forms a first waterfall from the first trough into the hollow basin and a second waterfall from the second trough into the hollow basin; and

moving the workpieces along the shackle line through the opening of the front end of the hollow basin, through the first and second waterfalls, and out through the opening of the rear end of the hollow basin;

wherein the solution comprises an antimicrobial agent and/or a pH adjuster.

18 . The method of claim 17 , further comprising collecting the solution in the hollow basin and recycling the solution back into the first and second waterfall assemblies.

19 . The method of claim 18 , wherein recycling comprises filtering the solution to remove solids therefrom.

20 . The method of claim 17 , wherein a distance between the first waterfall and the second waterfall proximate the front end is less than a distance between the first waterfall and the second waterfall proximate the rear end.
