Abstract: An automotive vehicle body painting system can be equipped with a paint purge mechanism that includes a densitometer responsive to density changes in the fluid flowing through the mechanism. The densitometer can be used to selectively direct pure paint into a pure paint collection receptacle or a solvent-paint solution into a mixed paint collection receptacle. The system achieves a relatively high percentage recovery of pure paint that is purged from the painting system during each paint color change.

Abstract: A system is provided for recycling a water ladened solvent used for purging a paint supply line of a paint sprayer. The purged material including a mixture of water ladened solvent and paint is filtered for separating the water ladened solvent from the paint. The water ladened solvent is collected and then reused for purging the paint supply lines of the paint sprayer.

Abstract: A tote tank has a flexible, collapsible liner for water-based or water-borne paint. The liner when full of paint fills the tank and lines the interior walls thereof. A paint outlet from the liner extends through a wall of the tank for withdrawing paint. A paint inlet to the liner is provided for filling the liner with paint and is normally closed and sealed by a closure plate. An air inlet to the tank allows the liner to collapse as paint is withdrawn. An air meter measures the amount of air entering the tank through the air inlet as an indication or measure of the amount of paint withdrawn.

A paint inlet to the liner is provided for filling the line with paint and is normally closed and sealed by a closure plate. An air inlet to the tank allows the liner to collapse as paint is withdrawn. The tank is mounted on a pivot and cranks are linked to the tank to rock it back and forth to keep the paint in an agitated condition.

Abstract: A method is provided for cleaning paint residue from the walls of an enclosed chamber and providing for reclamation of the cleaning solution. The method includes providing a regulated flow of cleaning solution under pressure to a hand held scrubbing apparatus for removing paint residue from the wall surface. The cleaning solution with the paint residue entrained therein drips down the walls and is collected in a series of troughs lining the perimeter of the paint booth. Taking advantage of gravity, the liquid drains from the troughs into a temporary storage container located below the paint booth. The liquid may then be pumped into a permanent storage container that could be in a remote location. The liquid is now available for reclamation.
