  • Patent number: 8974579
    Abstract: A device for separating paint overspray from the cabin exhaust air of painting systems which is laden with overspray having at least one separating surface, on which the cabin exhaust air can be guided along and which is electrically conducting and connected to a pole of a high voltage source. An electrode device arranged in the air stream is associated with the separating surface and connected to the other pole of the high voltage source. Paint overspray is transported away from the separating surface by an electrically conducting separating fluid, which can be fed to the separating surface and flows over the separating surface so that a large part at least of the solids pass from the cabin exhaust air flowing past into the separating fluid.

  • Patent number: 8945288
    Abstract: A device for separating overspray from the cabin exhaust air of painting systems includes at least one separating surface, on which the exhaust air is guided and which is connected to a pole of a high voltage source. An electrode device arranged in the air stream is associated with the separating surface and connected to the other pole of the high voltage source. The separated paint overspray is transported away from the separating surface with a separating fluid, which flows over the separating surface-from top to bottom. A discharge device having a channel open at the top is present, from which the separating fluid exits along the longitudinal extension of the discharge device when the level of the separating fluid in the channel exceeds an exit level, and reaches the separating surface such that the separating fluid flows downward on the separating surface as a substantially adhering layer.

  • Publication number: 20110186358
    Abstract: The invention relates to a device for continuously weighing powdered media in a tank, particularly paint powder in a storage tank, comprising a weighing unit having a measurement field on which a compressive force can be exerted, and by which an output signal representing the compressive force exerted on the measurement field can be generated. A guiding device allows forced motion of the tank having a vertical directional component. The tank can further be coupled to the weighing unit by forces by means of a coupling device, so that a compressive force that is dependent on the weight of the tank acts on the measurement field of the weighing unit when the tank is coupled to the weighing unit.

  • Publication number: 20100291848
    Abstract: A device for separating paint overspray from the air of painting cubicles that is laden with overspray has in a housing at least one separating element, the surface of which is electrically conductive and is connected to one terminal of a high-voltage source. The separating element is assigned an electrode arrangement, which is connected to the other terminal of the high-voltage source. The air of the cubicle is made to flow past the separating element and the electrode arrangement in such a way that the overspray particles are colonized and deposited on the surface of the separating element. The separating element is moved continuously or intermittently, wherein a wiping device wipes off the overspray that is on the surface of the separating element. This can then be carried away by a suitable transporting device for disposal or re-use.

  • Patent number: 7063486
    Abstract: A reservoir for powdery media, in particular powder coating, comprises a housing having at least one inlet and at least one outlet for the powdery medium. A fluidising floor of porous, air-permeable material is located in the interior of the housing at a distance from its base. A pressure chamber which is chargeable with compressed air is located between the fluidising floor and the base of the housing. The outlet has the shape of an upwardly open funnel which is located in the lower partial zone of the housing adjacent to the fluidising floor. In this way well-mixed powdery medium the grain-size distribution of which corresponds to the maximum extent to that of the fluidised powdery medium inside the reservoir is always withdrawn.

  • Patent number: 6964708
    Abstract: A booth for coating objects with powder, in particular for powder painting, comprises in a manner known per se a housing, in which there is situated at least one application device, with which powder can be applied to the objects. Situated in the upper region of the housing is an air plenum, which is fed with supply air via an inlet opening. The air plenum is closed off downwardly by a filter ceiling. In contrast to known filter ceilings, the one according to the invention is air-permeable in its marginal region only, while in its central region it consists of air-impermeable material. The supply air is thus introduced into the interior of the booth as a kind of “air curtain” which flows mainly along the side walls of the housing of the booth, entrains in the process stray excess powder which has not adhered to the objects to be coated, and supplies it to at least one extraction opening situated in the bottom of the booth.
