US 5,707,009 A · Rotary atomizer with a bell element

Abstract

A rotary atomizer with a bell element (1) mountable on the rotating shaft of a drive motor comprises an outer overflow surface (2), a spray edge (3) at a front side of the bell element (1), a lateral outer surface (5) at the perimeter of the bell element extending from the spray edge (3), and a hose line (9) in fluid communication with a source of cleaning fluid. Rinsing the outer surface (5) at the perimeter of the bell element (1) of a rotary atomizer is facilitated. The rinsing agent is directed without spattering, through centrifugal force, from the interior to the outer surface (5) and is distributed uniformly across the perimeter. The rinsing agent can branch off centrally from a fast-rinsing valve and move to a collection space (29, 15) located radially within the outer surface (5), from where it flows via the rear, preferably rounded bell dome edge (6). Alternatively, the rinsing agent can be supplied separately via a separate valve.

A rotary atomizer with a bell element mountable on a rotating shaft of a drive motor, comprising:

an outer overflow surface;
a spray edge at a front side of said bell element;
a lateral outer surface at the perimeter of said bell element extending from said spray edge;
a hose line in fluid communication with a source of cleaning fluid;
wherein a material to be atomized is moved from an inside space of said bell element to said outer overflow surface leading to said spray edge at said front side of said bell element;
wherein said cleaning fluid moves from said hose line to said lateral outer surface of said bell element;
said cleaning fluid flowing from a location in fluid communication with said hose line to said lateral outer surface by means of centrifugal action and is distributed across said outer surface for rinsing and cleaning of said lateral outer surface;
and
an interior space of said bell element leading to at least one outer rinsing channel distributed about an axis of rotation which leads into an outer annular space located at one point of said bell element turned away from said front side between a rearward edge of said outer surface and a hub section of said bell element, and from which said cleaning fluid flows, via said rearward edge onto said outer surface.
