초록 ▼

An electrostatic spray apparatus and method for spraying electrically conductive coating materials on a continuous basis from an electrically grounded bulk coating supply. Included is a spray gun from which electrostatically charged coating material is emitted toward an electrically grounded object to be coated; a high voltage source for electrostatically charging the coating material emitted from the gun; an electrically grounded bulk coating storage tank; and an intermediate tank assembly including a) an inner tank for continuously supplying coating to the gun via a hose, which inner tank is automatically and periodically replenished with coating material from the grounded bulk supply tank without establishing an electrically conductive path between the electrically grounded bulk storage tank and the inner tank which contains coating material electrostatically charged via the column of conductive coating material in the gun hose, b) an electrically grounded outer housing or container completely enclosing the inner tank, and c) an insulative support electrically isolating the inner tank from the outer grounded container, which support is subjected to a gaseous stream to prevent build-up thereon of a conductive film of coating material which, if permitted to occur, would shortcircuit the grounded outer container to the electrostatically charged coating material stored in the inner tank and thereby destroy the electrical isolation between the inner tank and the grounded outer container.

A method of electrostatically coating articles with electrically conductive material on a continuous basis with apparatus having all exposed surfaces thereof electrically grounded comprising: transferring uncharged electrically conductive material from an electrically grounded bulk storage tank to an inner container which is enclosed by and supported in spaced relation to an electrically grounded outer container by an insulative support physically contacting both the inner and outer containers, without establishing an electrically conductive path between said bulk storage tank and said inner container, transferring electrically conductive coating material through an electrically insulated conduit from said inner container to a spray device for emission thereby, electrostatically charging electrically conductive coating material emitted by said spray device, and sweeping a gas stream over said support while emitting electrostatically charged coating material to prevent deposition of a film of coating material on said support sufficient to conduct a substantial level of electrical current from said inner container to said outer container.
