ABSTRACT:
A self-cleaning vacuum head is disclosed which has the ability to discriminate between particles of different size, or the ability to separate fluids from particulate matter. The invention has two relatively moving surfaces which provide a changing locus of vacuum so that particles drawn against the surfaces are later separated therefrom. Each of the two surfaces has slots which are transverse to one another. The surfaces are moved relative to one another in a moving direction which is transverse to the orientation of the slots on the first of the moving surface, and also transverse to the slots on the second surface. The transverse arrangement of the slots, and the relative movement of the slots in a direction which is transverse to each of the slots causes particles drawn against the surface to roll about two substantially perpendicular axes to encourage thorough decontamination of the particles. An oil spill clean-up system is also disclosed utilizing the self-cleaning vacuum head.
