Abstract: PROBLEM TO BE SOLVED: To provide a powder spraying device which carries out electric charging simultaneously in the inside and the outside and is suitable for electrostatic powder coating. SOLUTION: Both of internal high voltage electrodes 2 and an external high voltage electrode 5 are connected with a high voltage power source through high resistance members 1, 3, 4 to improve adhesion efficiency to be constant without largely depending on the distance between the spraying apparatus and the member in a manufacturing process.

Abstract: The method involves a container (2) with a drain pipe (25). Air is introduced into the pipe through an opening and the adjustable air pressure controls the mass flow through the pipe from zero to a maximum value. The container is part of a powder spraying unit (1) and the powder is removed from a fluidised bed in the middle of it.

Abstract: A powder-spraying appliance for electrostatic powder coating of work pieces. In order to achieve particularly good charging of powder particles, the powder-spraying appliance contains a chamber, into which a powder/air mixture is introduced transversely to a spraying direction via a supply conduit. An earth electrode and a plurality of high-voltage electrodes are disposed in the chamber. All of the electrodes are flushed with cleaning air in order to avoid powder deposits on the electrodes.

Abstract: A powder spray device which is set up for a simultaneous internal and external powder discharge has a high voltage source (6), an earth electrode (10), at least one outer high voltage electrode (5) and several inner high voltage electrodes (2). The high voltage source is connected via connecting elements (3,4) made of highly resistive material not only to the outer high voltage electrode but also to a ring (1) made of highly resistive material, over whose periphery the inner high voltage electrodes are distributed evenly. As a material for the highly resistive components, a plastic is used which is filled with graphite, rust or other conducting material.

Abstract: The gun has a chamber (1) into which is blown the powder/air mixture via a lateral duct (11). This generates a swirl action and the exit of the chamber passes HT electrodes (7) before being expelled via a deflector plate (9) to spread the powder spray. The earthing electrode (5) is surrounded by a sheath and has clean air blown through the space between the sheath and the electrode. The air keeps the electrode clean of powder deposits. The spacing of the electrodes is adjustable and the HT electrodes are in a ring, or in several rings. The HT electrodes are similarly supplied with cleaning air flows.

Abstract: The invention relates to a powder spraying device for electrostatic powder coating of workpieces. In order to achieve a particularly good powder particle charge, the powder spraying device (10) contains a chamber (1) into which a powder/air mixture (PL) is introduced crosswise to the spraying device (13) by means of a feed pipe (11). A ground electrode (5) and multiple high-voltage electrodes (7) are placed in the chamber (1). All electrodes (5, 7) are swept by purified air (RLE, RLH) in order to prevent powder deposits.
