Abstract
A rotary atomizer including a bell element having a paint tube, a deflector having a conical distribution surface opposite the paint tube outlet, including a tip portion within the paint tube, directing paint to a paint overflow surface through an annular conical channel adjacent the outer edge of a nonconductive end face, an annular electrostatically charged surface surrounding the outer edge of the end face generating an annular electrostatic field and an axial electrode having a sharp distal end in the plane of the annular electrostatically charged surface generating a second axial electrostatic field.
Claims26
An atomizer for powder paint including a rotary bell element, comprising:
- a nonconductive end face;
- a generally axial paint tube;
- a deflector having a distribution surface opposed to said paint tube directing paint radially and axially toward an overflow surface through an annular channel having opposed paint distribution surfaces;
- an annular electrostatically charged surface surrounding said nonconductive end face adjacent said end face of said bell element generating an annular electrostatic field;
- and
- an axially extending central electrostatically charged electrode having a distal end generally in the plane of said annular electrostatically charged surface generating an axial electrostatic field of generally the same charge as said annular electrostatic field.
An atomizer for powder paint including a rotary bell element comprising:
- a nonconductive end face having a generally circular outer edge;
- an axial paint tube extending toward and generally perpendicular to said nonconductive end face;
- a deflector having a paint distribution surface opposing an outlet of said paint tube directing paint into an annular generally conical passage to an overflow surface adjacent said outer edge of said nonconductive end face;
- an annular electrostatically charged surface adjacent said outer edge of said nonconductive end face generating an annular electrostatic field surrounding said nonconductive end face;
- and
- a central electrode extending axially through said nonconductive end face electrostatically charged at substantially the same electrical potential as said annular electrostatically charged surface having a distal end generally in the plane of said annular electrostatically charged surface and generating an axially extending center electrostatic field increasing the deposition efficiency of said atomizer.
An atomizer for powder paint including a rotary bell element, comprising:
- a nonconductive end face having a central depression, a planar surface surrounding said depression and a circular outer edge;
- an axial paint tube extending toward and generally perpendicular to said planar surface of said nonconductive end face having an outlet;
- a deflector having a generally conical paint distribution surface opposing said outlet of said paint tube directing paint through an annular passage to a paint overflow surface adjacent said outer edge of said nonconductive end face;
- an annular electrostatically charged surface adjacent said outer edge of said nonconductive end face generating an annular electrostatic field surrounding said nonconductive end face;
- and
- a central electrode having a sharp distal end extending through said central depression of said nonconductive end face substantially in the plane of said planar surface of said nonconductive end face electrostatically charged at substantially the same electrical potential as said annular electrostatically charged surface generating an axially extending electrostatic field increasing the deposition efficiency of said atomizer.
