摘要： A method and system for maintaining a uniform volume of powder in a powder feeder provided. The system includes a supply hopper that is spared from a powder feeder. The powder includes a receiving opening and a discharge opening. A rotatable brush is in communication with the supply hopper for causing powder withdrawn from the supply hopper to be transported to the powder feeder and disposed uniformly across the receiving opening of the powder feeder. The brush is immersed within the powder and extends across the receiving opening of the powder feeder, and maintains a filled level powder feeder.

摘要： A method and apparatus for coating a metal substrate with a finely divided powdered material, which method includes the steps of providing a supply of resin particles adjacent a coating zone, releasing a gentle flow of gas through the supply of resin particles to permit the particles to flow freely, delivering a uniform flow of particles to a comminuting site, releasing the fluid energy of a compressed gas to the flow of resin particles to impart sufficient momentum to said resin particles to reduce their average particle size to a very finely divided resin particle size of 10 microns or less, providing a flow of finely divided resin particles and diffusing the flowing gas to provide a substantially quiescent, slowly and upwardly moving gas stream to maintain the very finely divided resin particles segregated in a uniform cloud and to carry said cloud to the coating zone; confining said cloud of very finely divided resin particles in the coating zone, said particles having a diameter-to-weight ratio such that they will remain suspended in the substantially quiescent atmosphere of the coating zone; moving sheet metal stock to be coated in strip form through the coating zone; and providing an electric charging and depositing field terminating on the metal stock strip in the coating zone having a potential gradient sufficient to charge the finely divided resin particles and deposit said particles on the metal surface while the particles are in a repelling relationship with respect to one another thereby providing a uniform distribution of particles on the strip.

摘要： A powder atomizer comprises a pan, and an element journaled for rotation about an axis. The pan partially surrounds the element, and therewith defines a venturi into which powder is fed. The venturi has an inlet and a spaced outlet. A motor rotates the element within the pan in excess of the speed required to throw powder from the element by centrifugal force and draws gas through the venturi, so that powder fed into the element is atomized and produces a uniform cloud of particulate material. A nonconductive element minimizes the electrical charge on the pan, and thereby the resulting agglomerization of particulate material at the outlet.

摘要： An electrostatic powder coating apparatus comprising a powder reservoir, a gas flow injection chamber, a diffusion chamber and a coating chamber and method for coating a substrate or target objects. The injection chamber receives powder from the reservoir at a controlled rate. The powder particulates are entrained by a gas flow within the injection chamber. The diffusion chamber receives the particulates from the injection chamber. The diffusion chamber deaccelerates the particulates and creates a particulate cloud. The coating chamber receives the particulate cloud. A housing encloses the coating chamber. The coating chamber is isolated from the ambient atmosphere. The coating chamber has a cloud inlet and a cloud outlet. The cloud flows through the coating chamber from the inlet to the outlet. One or more deflectors, within the chamber, define a passage and two or more pockets adjoining the substrate or target objects. The deflectors deflect the carrier gas from the pockets to the substrate or target objects. The substrate or target objects are transported within the chamber along the passage. Coating material within the passage is concentrated around the substrate or target objects. The coating chamber includes electrodes and voltage biasing means. The biasing means acts upon the substrate or target objects which are positioned within the passage. The particulates are electrostatically deposited upon the substrate or target objects within the passage.

摘要： An apparatus and method is detailed for the application of non-conductive material, generally of a powder or fine fiber form from bulk storage onto a conductive filament or plurality of filaments. A series of vibrating troughs are used to store, convey, unpack and load particulate material at a controllable rate into a gas stream traversing a converging-diverging nozzle. High aerodynamic shear in the nozzle reduces the material's size. Divergent nozzle exit geometry slows the material to speeds where electrostatic forces can predominate, as the material is injected upwardly into a chamber fitted with a cascade of conical forms. Each cone is electrified about its circumference in one or more locations, with respect to a centrally located upward moving filament. Conventional electrostatic charging and deposition on the filament is augmented by the convergent geometry of the cones. Excess material falls on the outside of the cones, and eventually downward to a recovery area. An exhaust system provides vertical velocity augmentation to the particulate cloud, plus a clean exit of the filament. Single, multiple and cabled filaments can be coated in a single apparatus.
