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.

Claims2

Dependent claims

A method for cleaning a vehicle white body, said white body being transported by a movable assembly toward and away from a cleaning solution tank, said cleaning solution tank including a main tank and a weir tank, said weir tank being located upstream said main tank, each of said main tank and said weir tank holding a volume of cleaning solution and including an outlet from which cleaning solution flows into a filtration system, said filtration system providing filtered cleaning solution, via at least one deluge cannon, for injected into an interior of said white body, said method comprising the steps of:

providing said at least one deluge cannon at a location such that, after said cleaning solution is injected into said white body interior via said at least one deluge cannon, said cleaning solution and particles derived from said white body interior flow into said weir tank;
moving said white body via said movable assembly over said weir tank and toward said main tank;
draining cleaning solution and particles from said cleaning solution tank;
filtering particles from said cleaning solution to provide filtered cleaning solution;
pumping said filtered cleaning solution to said at least one deluge cannon and injecting said filtered cleaning solution into the interior of said white body;
lowering and immersing said white body in said main tank;
and,
raising and withdrawing said white body from said main tank.
