  • Patent number: 10618198
    Abstract: The invention relates to a device (01, 19, 23) for foaming a viscous material (02), said viscous material (02) being conveyed through a first conveyor pipe (05) using a first conveying means (04) at a first conveying pressure, and a gas (07) being conveyed through a second conveyor pipe (08) at a second conveying pressure, and the second conveyor pipe (08) and the first conveyor pipe (05) becoming conjoined at an opening (15), and a discharge device (17) being provided downstream of the opening (15) so as to allow a pressure-relieving discharge of the mixture (14) made up of viscous material (02) and gas (07), a gas injection valve (09) being arranged at the opening (15), said gas injection valve (09) allowing to inject gas bubbles (25) into the viscous material (02).

  • Patent number: 6852164
    Abstract: A central powder supply system, referred to as a so-called powder center (1) is made available for use especially in high-performance industrial powder coating installations. The powder center (1) is divided into two separate chambers (2, 3), an operating chamber (2) and a powder chamber (3). Both chambers (2, 3) can be connected with a powder separating device via an opening which can be closed off. The powder chamber (3) essentially houses the powder preparation device (5), while the operating chamber (2) contain the operating parts (22) and supply parts (20, 21). The powder preparation device (5) comprises a height-adjustable lifting table (7) with vibration device for the powder supply container (6 positioned thereon. In addition, there is a suction plate (12) which serves as suction device and has through openings (13). The suction plate (12) is surrounded by a strain basket (17) which, optionally, has a support basket (18).

  • Patent number: 6616764
    Abstract: A method for cleaning an interior of a coating booth is proposed in which blast air is used as at least one of the means for cleaning. For primary cleaning of the coating booth, blast air and corresponding suction operations are used, whereby blowing and suction can be carried out simultaneously, cyclically or sequentially. The invention also relates to a coating booth. The floor and/or the ceiling of the coating booth are formed by a separate floor part and/or a ceiling part which are movable relative to the peripheral wall. The floor part and/or the ceiling part include a cleaning device which can optionally be integrated with the respective floor part and/or ceiling part. The floor part and/or the ceiling part hence operate as a cleaning device for the coating booth. The cleaning device can be displaced in the interior space of the coating booth in a longitudinal direction.

  • Patent number: 6187098
    Abstract: A powder coating cabin includes a column-like housing defining an interior space between a ceiling and a bottom, with the bottom being substantially of flat configuration, and a coating unit arranged on the housing for spraying powder onto an object. The powder coating unit is further provided with a cleaning unit which is so received in the housing as to be movable between a stand-by position in which the cleaning unit is arranged at least partially underneath the bottom and an operative phase for automatically cleaning at least the inner wall surfaces of the housing, whereby the bottom is suitably so designed as to clear a passage for the cleaning unit.
