## Abstract

A pre-clean deluge system for cleaning automobile white bodies including a cleaning solution filtration and distribution system. The filtration system includes a series of filters specially adapted to remove metal particles from the cleaning solution. The distribution system includes deluge cannons that are position so as to deliver cleaning solution to the interior of the white body in a location during the white body travel so that the particles flushed therefrom are introduced into a small tank prior to a main tank in which the white body is subsequently immersed. The distribution system also provides regulated flow of cleaning solution to the deluge cannons, as well as a bypass to facilitate cycling of cleaning solution for end-of-shift filtration purposes.

## Claims

### Claim 1

A deluge cleaning system for filtering and distributing a cleaning solution to a vehicle white body as part of a pre-paint process, said system comprising:
a cleaning solution tank comprising a main tank and a weir tank, said weir tank being located upstream of said main tank, said white body being at least partially immersed in said main tank after traveling past said weir tank;
at least one deluge cannon through which pressurized cleaning solution flows into an interior of said white body;
a pump means;
a filtration system comprising a series of filters that are adapted to remove metal particles from said cleaning solution, said filtration system and pump means cooperating to provide said pressurized cleaning solution to said deluge cannon;
wherein said at least one deluge cannon is disposed at a location such that said white body is flooded with said pressurized cleaning solution prior to immersion in said main tank and wherein cleaning solution and entrained particles flow from said white body and into said weir tank.

### Claim 2 (depends on 1)

A deluge cleaning system according to claim 1, further comprising a flow regulator, said flow regulator being disposed between said pump means and said at least one deluge cannon and serving to regulate cleaning solution flow through said at least one deluge cannon.

### Claim 3 (depends on 2)

A deluge cleaning system according to claim 2, further comprising a bypass conduit and a three way valve wherein, when said valve is in a first position, said cleaning solution is delivered to said at least one deluge cannon and, when said valve is in a second position, cleaning solution is cut off from said deluge cannon and instead flows through said bypass conduit to said tank.

### Claim 4 (depends on 3)

A deluge cleaning system according to claim 3, wherein said pump means includes at least one primary pump and at least one secondary pump, said primary pump supplying cleaning solution to said deluge cannon and said secondary pump supplying cleaning solution to at least one spray bar, said spray bar being positioned to spray cleaning solution on an exterior of said white body.

### Claim 5 (depends on 3)

A deluge cleaning system according to claim 3, wherein said filters include a gross filter, a centrifugal filter, and a magnetic filter.

### Claim 6 (depends on 1)

A deluge cleaning system according to claim 1, further comprising a bypass conduit and a three way valve wherein, when said valve is in a first position, said cleaning solution is delivered to said at least one deluge cannon and, when said valve is in a second position, cleaning solution is cut off from said deluge cannon and instead flows through said bypass conduit to said tank.
