摘要： In a coating plant, the powder feed device is cooled permanently in order to avoid the deterioration of the powder which could be caused by an excessively high temperature. The air for the fluidization of the powder contained in the reservoir (1) is cool, dry air. A heat exchanger (30) supplies a closed loop circuit which includes an annular cooling chamber (32) and a coil (33) arranged in the path of the powder. The shaft of the worm screw may also be cooled.

摘要： A powder feed device for supplying a powder dispensing apparatus such as a powder spray gun of an electrostatic powder deposition system. Entrained powder is extracted from a fluidization tank and transported through a half-inch diameter tube or hose to the dispensing apparatus. To prevent clumps of powder and/or powder adhering to the walls of the tube or hose while permitting reduced air flow speed of about 2 to 3 m/s an electric field is provided in the tube or hose and applied by an outer conductor extending around the tube or hose and an inner wire conductor inside the tube or hose extending in the direction of the flow of entrained powder, which conductors are connected across an AC voltage source. The electric field may operate constantly or intermittently.

摘要： Electrostatic powder-coating method, whereby a flat fan-spray of electrically charged powder particles is directed toward an object to be coated, said spray being formed from an incident stream consisting of a mixture of powder and carrier-gas, comprising means for re-homogenizing said incident stream, means for subsequently deflecting said stream in a direction substantially perpendicular to its incident direction, means for thereafter driving said stream against the internal walls of a duct designed to convert said stream into a fan-shaped spray, and means for electrically charging the powder particles of the said spray. The re-homogenizing means may, however, be omitted in certain cases.

摘要： An electrostatic spraying installation for low-resistivity paint comprises a conveyor which conveys large objects such as automobile bodies, to be painted with a substantially constant distance between their respective leading edges. A plurality of sprayers is positioned to paint respective specific parts of the objects as they are conveyed past the sprayers by the conveyor. A respective spray member in each sprayer is connected to a high-tension electrical supply. All the spray members are substantially situated in a common plane perpendicular to the path of movement of the objects along the conveyor or in a plurality of planes perpendicular to this path and spaced from each other by the previously mentioned substantially constant distance. A plurality of electrically grounded closed loop primary paint circulation circuits each contain paint of a respective color different than the color of the paint in each of the other primary circuits. A plurality of intermediate storage tanks electrically insulated from ground, equal in number to the primary circuits, are each assigned to a respective primary circuit. An arrangement for selectively connecting each intermediate storage tank to the respective primary circuit is provided and a plurality of selector valves connects each intermediate storage tank selectively to the sprayers. A control system operates the selective connection arrangement or a subset thereof only when none of the spray members is connected to the high-tension supply. Under this condition, the control system operates paint change units simultaneously when all the sprayers are facing the spaces between the objects.
