Abstract

A baffle assembly for intercepting paint particles passing through a spray booth is disclosed. The baffle assembly includes an inner plate and an outer plate adjacent each end or edge of the inner plate. The inner plate is comprised of a central planar portion, which is oriented substantially perpendicular to the direction of air flow, and having outer ends which are curved in an upstream direction and inwardly toward one another. Each outer plate includes a curved portion which terminates in a semi-circular portion. The inner plate is received and positioned within the outer plates so that each of its outer ends is substantially surrounded by and equidistant from its adjacent outer plate. In this manner, air flows between the inner plate and the outer plate in a first curved direction and then in a second opposite curved direction.

Dependent claims

A baffle arrangement for removing particles from an air stream passing therethrough, said baffle arrangement comprising:

a first plate member comprising a longitudinally extending planar portion and oppositely disposed longitudinally extending curved outer ends, said longitudinally extending planar portion being interposed between said oppositely disposed longitudinally extending curved outer ends,
a second plate member comprising a longitudinally extending first curved portion and a longitudinally extending second curved portion, said longitudinally extending first curved portion having a curvature which approximates the curvature of one of said longitudinally extending curved outer ends of said first plate member, said longitudinally extending first curved portion terminating in said longitudinally extending second curved portion of said second plate member;
and
a third plate member comprising a longitudinally extending first curved portion and a longitudinally extending second curved portion, said longitudinally extending first curved portion having a curvature which approximates the curvature of the other of said longitudinally extending curved outer ends of said first plate member, said longitudinally extending first curved portion terminating in said longitudinally extending second curved portion of said third plate member,
said first plate member being received and positioned within said second plate member and said third plate member so that said one of said longitudinally extending curved outer ends of said first plate member is substantially surrounded by said second plate member, and said other of said longitudinally extending curved outer ends of said first plate member is substantially surrounded by said third plate member.
