Abstract
In combination with electrical ionizing devices (A.C. static neutralizers or D.C. charging systems) in which discharge electrodes, such as emitter points, are connected to a high voltage power supply and in adjacently spaced disposition behind a grounded foraminous grille, wiper means, such as brushes, for cleaning accumulations of particulate material electrostatically adhered to the electrodes themselves. The brushes are preferrably mounted upon the grille and have bristles passing through slots therein to enable the operator before ionization is instituted to sweep the brushes from an out-of-the-way position relative to the emerging ion flow across the electrodes to effect the cleaning and then clear of said electrodes.
Claims9
In combination with an extended-range, dual-polarity static eliminator having a plurality of pointed discharge electrodes adapted to be coupled to a high voltage power source and arranged in at least one row enclosed within the interior of an apertured grounded housing with the pointed tips of the electrodes spaced behind an apertured protective grille of said housing, electrode cleaning apparatus comprising:
- an elongated slot in said housing corresonding to each row of pointed tips and substantially coextensive therewith,
- brush means, including a base portion slidably supported within the edges of each slot and a bristle portion projecting therethrough for sweeping contact with the discharge electrodes, and
- a handle positioned external to said housing for oscillating the brush means across the tips of said electrodes to effect removal of foreign particulate material therefrom when said handle is traversed across the slot.
In combination with a dual polarity static eliminator having a plurality of pointed discharge electrodes arranged in a longitudinally extending row enclosed within the interior of an apertured housing with the pointed tips of the electrodes adjacently spaced from the apertured portion of said housing, and including blower means in said housing for directing air across said discharge electrodes through the apertures therefor, electrode cleaning apparatus comprising:
- an elongated slot in said housing substantially coextensive with the row of pointed electrodes,
- a brush having a base portion slidably supported within the slot in said housing and including bristles for sweping across the tips of the electrodes,
- a handle positioned external to said housing and coupled to said base portion for oscillating the brush within said housing across the tips of said electrodes to effect cleaning thereof, and
- means associated with said handle for retracting said brush to a position clear of said discharge electrodes when said static eliminator is in use, whereby foreign particulate may be cleaned from said electrodes without interfering with static neutralization.
