Disclosed herein is a powder container for supplying coating powder to a powder coating station. The powder container includes a powder compartment for coating powder, the powder compartment being delimited by side walls, one of which is provided with an outlet port via which the powder compartment is or can be fluidically connected to an inlet of a powder deposition system. The effective flow cross-section of the fluid connection between the outlet port and the inlet of the powder deposition system can be variably adjusted.

The objective of this invention is to provide a filter module for coating equipment that can improve the efficiency in removing coating-material mist and preventing the outflow of such coating-material mist to the outside. The filter module of this invention is made of a flammable material and includes an outer box, an eliminator and a baffle plate. Of the outer box, the air A2 containing the coating-material mist flows into the outer box from the outer-box inlet and is discharged from the outer-box outlet. The eliminator is formed by arranging zigzag-shaped eliminator elements in parallel to separate the coating-material mist from the air A2. The baffle plate is formed by arranging baffle-plate elements having an inclined surface for guiding the air A2 in parallel into the inflow-side space S2 of the eliminator, and guides the air A2 that has been introduced from the outer-box inlet to the inflow-side space S2.

A holding device for filter elements of a filter module for separating overspray from booth air of a coating installation, in particular painting installations, which booth air is laden with overspray, the filter module having a filter housing, which bounds a filter chamber, through which booth air laden with overspray can be conducted in a main flow direction, a plurality of filter elements made of a filter material permeable to the booth air being arranged in the filter chamber in such a way that a flow labyrinth is formed between the filter elements, the holding device being designed to hold one or more filter elements and to position said one or more filter elements within the filter module, the holding device extending along a longitudinal axis, which is arranged transversely to the main flow direction, the holding device having a grate structure that forms the outer contour, and the one or more filter elements being holdable by means of the grate-type outer contour and thus being positionable relative to the outer contour in a stationary manner.

A feed center for powder coating material includes a hopper, an extraction duct, and a control valve. The hopper is in fluid communication with a fluidizing pressure source. The extraction duct is in fluid communication with at least one suction source. The control valve connects the extraction duct with an extraction port of the hopper. The control valve is operable between a first position for applying suction from the at least one suction source to the hopper, and a second position providing an exterior opening in at least one of the control valve and the first extraction duct for exhausting pressurized fluid from the hopper and/or collecting at least some of the air and powder that is exhausted from the powder.

Provided is an operation method for a coating exhaust treatment system that includes a filter configured to filter discharged air discharged from a coating chamber in which a coating object is spray-coated and collect overspray coating material included in the discharged air, and a powder dispersal means configured to disperse powder for forming a filter covering layer in the discharged air and form a filter covering layer made of a layer of the accumulated powder on a surface on the filter as the discharged air passes through the filter, the method including, when the number of repetitions of a first operation reaches a set number while the first operation and a second operation are being repeatedly carried out alternatingly, discarding coating material-containing powder and supplying fresh powder to a first supply tank, and when the number of repetitions of the second operation reaches the set number, discarding the coating material-containing powder and supplying the fresh powder to the second supply tank.

An arrangement is disclosed for the preferably automatic coating of objects with a coating material, in particular coating powder. The arrangement includes at least one spray device having a spray nozzle via which the coating material is dispensable in a main spraying direction. An extension is further provided, wherein an end region of the extension facing the spray device is preferably detachably connected to an end region of the spray device associated with the extension opposite from the spray nozzle. The arrangement further includes a preferably horizontally extending guide via which the extension with the spray device connected thereto can be longitudinally moved in the direction of extension of the guide relative to the object to be coated. The main spraying direction of the spray nozzle may be implemented so as to deviate from the direction of extension of the guide by a predefined or definable angle.
