Abstract: The invention relates to a powder spray coating booth (1) in which objects can be coated with powder with the aid of at least one spray device (6), wherein the powder spray coating booth (1) has an exhaust channel arrangement for exhausting air and excess powder from the booth interior of the powder spray coating booth (1), and wherein the exhaust channel arrangement has an exhaust channel (9) which is arranged in the booth substructure and which is fluidically connected to the booth interior via at least one exhaust opening (8). In order to achieve that a change of powder can also be quickly carried out, the invention provides that the exhaust channel (9) is additionally fluidically connected or can be additionally fluidically connected to at least two channel sections (31, 32) which are led out of the booth substructure, via a manifold (30) arranged in the booth substructure.

Abstract: The present invention relates to a powder feeding device (100), in particular for coating powder. The powder feeding device (100) comprises a dense phase powder pump (1) which has at least one conveying chamber (4) with a powder inlet valve (7) and a powder outlet valve (8). Furthermore, a control device (90) is provided for selectively operating the dense phase powder pump (1) in a powder conveying operating mode or a flushing operating mode. The powder inlet valve (7) and the powder outlet valve (8) of the dense phase powder pump (1) are configured in each case as a pneumatically actuable compression valve which can be closed when an actuating pressure is applied. It is provided according to the invention that the control device (90) is configured to set the pressure value of the actuating pressure which is selected for closing the powder inlet valve (7) and/or powder outlet valve (8) preferably automatically and more preferably selectively automatically depending on the respective operating mode of the dense phase powder pump (1) and/or depending on a pressure which prevails in the conveying chamber (4).

Abstract: The invention relates to a powder conveyor (100) having a pneumatically actuated dense phase powder pump (1) and a pressure controller (91). The dense phase powder pump (1) comprises at least one conveyor chamber (4) having a powder inlet valve (7) and a powder outlet valve (8). The pressure controller (91) can be used to adjust and maintain a set pressure on the at least one conveyor chamber (4) of the dense phase powder pump (1) that is or can be previously defined and/or to adjust and maintain an actuation pressure on the powder inlet valve (7) or the powder outlet valve (8) that is or can be previously defined. According to the invention, the powder conveyor further comprises a gas flow detection device (D1, D2, D3, D4) for detecting or determining a quantity of gas that is fed or removed per time unit when the set pressure is adjusted and maintained on the at least one conveyor chamber (4) or a quantity of gas that is fed to the powder inlet valve (7) or the powder outlet valve (8) per time unit when the actuation pressure is adjusted and maintained. An evaluation device (92) compares at least one detected or determined gas flow value with a corresponding set value and automatically generates an error and/or alarm signal when a deviation is detected.

Abstract: The invention relates to a method and a dense phase powder pump (1) for conveying coating powder from a first powder reservoir (101) to a second downstream powder reservoir or to a downstream powder spray-coating gun (102) or the like installation for spraying coating powder. In order to reduce the number of components of the dense phase powder pump (1) that require maintenance, the dense phase powder pump (1) is designed as a single-chamber dense phase powder pump and has only a single powder conveyor chamber (4) for conveying coating powder.
