A powder conveying chamber for a dense-phase powder pump for conveying powder, in particular coating powder, has an end region via which the powder conveying chamber is or can be fluidically connected to a powder line, wherein the end region of the powder conveying chamber is configured as a transition region and designed to reduce an effective flow cross-section of the powder conveying chamber to an effective flow cross-section of the powder line and/or to an effective flow cross-section of a valve arranged between the powder conveying chamber and the powder line, in particular a pinch valve. In particular, a cleaning system is associated with the end region, with which the end region can be supplied with cleaning air in the form of pressurized air, in order to keep the end region free of powder deposits or in order to remove powder deposits in the end region.

Powder conveying chamber for a dense phase powder pump and dense phase powder pump comprising a powder conveying chamber

The invention relates to a separating powder filter, particularly for supplying different types and/or sorts of powder, as selected, to a powder delivery device. The separating powder filter comprises the following: a first powder inlet, at least one additional, second powder inlet, and a powder outlet. Either the first powder inlet or the at least one second powder inlet can be fluidically connected to the powder outlet of the separating powder filter.

Separating powder filter and powder delivery system comprising a separating powder filter

The invention relates to a powder supplying device for a powder coating installation with at least one powder container, which has a powder chamber for coating powder, and with at least one powder injector, which is connected or can be connected to a powder discharge channel opening out via a powder discharge opening in the powder chamber, in order to suck coating powder out of the powder chamber in the powder coating operation of the powder coating installation with the aid of conveying compressed air fed by the powder injector. In order to make it possible for the powder to be changed quickly in an easy manner, it is provided according to the invention that the powder discharge channel has a reduced length of at most 300 mm, preferably a length of 160 mm to 240 mm and more preferably a length of 200 mm.

Powder supplying device for a powder coating installation

The invention relates to a device for conveying coating powder from a powder container. The powder conveying device has a powder conveying pipe having a powder inlet, by means of which coating powder can be fed from a powder container to the powder conveying pipe, in particular by means of suction. Furthermore, a powder conveying pipe retainer is provided in order to retain the powder conveying pipe. The powder conveying pipe can be preferably optionally moved in relation to the powder conveying pipe retainer in the longitudinal direction of the powder conveying pipe, wherein in order to clean the powder conveying pipe, the powder inlet of the powder conveying pipe can be closed and a compressed air line can be connected to the powder pipe.

Device for conveying coating powder from a powder container

A powder supplying device for a powder coating installation with at least one closable powder container, which has a substantially cuboidal powder chamber for coating powder and a fluidizing device for introducing fluidizing compressed air into the powder chamber. At least one inlet opening is provided in a side wall of the powder container for feeding coating powder during a powder coating operation of the powder coating installation or for introducing cleaning compressed air during a cleaning operation of the coating installation. At least one outlet is provided for discharging fluidizing compressed air introduced into the powder chamber or for discharging cleaning air introduced into the powder chamber during the cleaning operation together with residual powder transported along with the cleaning compressed air. At least one powder feed line and at least one cleaning compressed-air feed line are connected via a diverter to the at least one inlet opening.

Powder supplying device and method for automatically cleaning a powder supplying device

A powder supplying device for a powder coating installation with at least one closed or closable powder container, which has a cuboidal powder chamber for coating powder. In order to quickly change the powder, one or more cleaning compressed-air inlets to which a compressed air source can be connected in a cleaning operation of the powder coating installation for removing residual powder from the powder chamber, in order to introduce cleaning compressed air into the powder chamber, is provided in a side wall of the powder container.

Powder spray coating cart

A compressed air throttle apparatus has at least one throttle valve adjusted by an electric motor, and an electric circuit fitted with contacting elements to alternatively interrupt and close the electric circuit in relation to the throttle valve settings. This throttle apparatus preferably is applicable to a compressed air path of powder spraycoating equipment.

Compressed air throttle device and a powder spray coating device

A powder spraycoating gun and its gun housing. The spraygun housing is a plastic, integral body constituting a stock fitted with a powder discharge tube and a grip fitted with a powder intake tube.

Power spray-coating gun and gun-housing

A spray apparatus for coating material, in particular for coating powders, contains a spray outlet spraying the coating material, a shaping air outlet in the form of a plurality of holes shaping the spray jet and an ambient-air passage radially configured between the spray outlet and the holes to aspirate ambient air by means of the flow suction effect of the spray jet and/or of the shaping air flow.
