The disclosure relates in particular to an apparatus for disinfecting at least one room, in particular for one or more persons, preferably a dwelling space or treatment room, for example a treatment room in a building, in particular a sickroom, a patient room and/or an operating theatre, by means of an atomiser. Specifically, the apparatus is characterised in that the atomiser includes a rotatable bell cup for atomising a disinfectant into the room. The disclosure relates to an associated method and furthermore to the use of a bell cup for atomising a disinfectant in a room for, in particular, one or more persons.

Disinfection device

The disclosure relates to an operating method for a coating system, in particular for a painting system, for coating components (), in particular motor vehicle body components (), having the following steps:

Coating system and associated operating method

Axial turbine housing for a rotary atomizer for a painting robot

A rotary atomizer turbine is provided, the turbine including a turbine wheel with multiple turbine blades, a blade duct containing the turbine blades and being delimited radially by a duct wall, a braking air nozzle, a driving air nozzle and an outlet region at the outlet of the driving air nozzle. The outlet region is delimited at the outside by the duct wall of the blade duct and at the inside by the turbine blade respectively passing through it. The blade duct is delimited radially at the inside opposite the braking air nozzle by a stationary flow barrier. Furthermore, the outlet region of the individual driving air nozzles is a divergent cross-sectional region which widens in the flow direction and rotates with that turbine blade passing the driving air nozzle.

Rotary atomizer turbine

A turbine rotor, e.g., for a drive turbine of a rotary atomizer, is disclosed having a rotatably supported turbine shaft with the potential for mounting an atomizer wheel, and having at least one drive turbine wheel having a plurality of turbine blades. The turbine blades of the drive turbine wheel may be impinged on during operation by a drive fluid in order to drive the turbine rotor. The drive turbine wheel may be designed for the drive fluid to axially impinge on the turbine blades. A complete drive turbine having such a turbine rotor is also disclosed, as well as a complete rotary atomizer and individual exemplary components of the drive turbine.

Axial turbine for a rotary atomizer

A rotary atomizer is disclosed, comprising an atomizer bell and a shaft carrying the same. The rotary atomizer may further include a retainer between the atomizer bell and the shaft, said retainer preventing, e.g., by the action of a centrifugal force, the atomizer bell from detaching itself from the shaft.

Rotary atomizer comprising an atomizer bell and a retainer

A rotary sprayer for a coating apparatus is disclosed. An exemplary rotary sprayer may include a spraying body configured to be mounted on a drive shaft of a drive motor for rotation with the drive shaft. The spraying body may further include a detachable mounting device for coaxial connection of the spraying body to the drive shaft. The detachable mounting device may include a spraying body thread that mates with a driveshaft thread defined by the drive shaft, and a plurality of elastic tabs configured to abut a corresponding cavity defined by the driveshaft, such that rotation of the spraying body increases an abutment force between the elastic tabs and the corresponding cavity of the driveshaft.

Rotary atomizer with a spraying body

For grounding or electrically charging the shaft of an electrostatic rotary atomizer working with external or direct charging, there are opposing, annular or spiral-shaped sharp edges in the outer surface of a part of the shaft and in the inner surface of a stationary bearing part at the desired potential, which have different, preferably opposite, thread directions, so that the edges intersect each other at points.

Potential neutralization arrangement for an electrostatic rotary atomizer

A deflecting air ring includes a plurality of deflecting air nozzles for discharging a deflecting air jet onto a spray jet of a vaporizer in order to shape the spray jet. The deflecting air nozzles are configured such that the deflecting air jet is substantially laminar within a first region, while the deflecting air nozzles also generate turbulence in a second region situated downstream of the first region of the deflecting air jet.

Deflecting air ring and corresponding coating process

A transformer arrangement is disclosed for an electrostatic sprayer or in an adjacent moving element of a coating machine. A transformer provides a galvanic isolation between the line arrangement provided for supplying power to the sprayer arrangement, and consumers at high voltage in the sprayer or possibly in the robot arm. This isolation may be provided with an isolating transformer which has a sufficient isolation distance or other isolation device between the primary and secondary circuits.

Electrostatic spraying arrangement

A deflecting air ring is disclosed having a plurality of deflecting air nozzles for discharging a deflecting air jet onto a spray jet of a vaporizer in order to shape the spray jet. The deflecting air nozzles are configured such that the deflecting air jet is substantially laminar within a close region, while the deflecting air nozzles also generate turbulence in a remote region situated downstream of the close region of the deflecting air jet.

An atomizer assembly () drives an atomizing bell () to apply paint onto a part (). The atomizer assembly () includes a core () having at least one paint line () extending therethrough, a turbine device () circumscribing an axis (A) and disposed in the core (), and a turbine unit () surrounding the pain line () and having a shaft () rotatable relative the turbine device () with several turbine blades () connected to the shaft (). A plurality of nozzles () are defined in the turbine device () and are positioned relative a turbine wheel () connected to the shaft () to drive fluid, i.e. gas onto the turbine blades (). An annular wall () extends outwardly from one of the terminal ends of the turbine device () to define a seat () for engaging the core () to maintain a fixed gap between the paint line () and the shaft () and to eliminate contact therebetween.

High speed rotating atomizer assembly

The bell shaped plate of a rotary sprayer is attached to its drive shaft by means of a detachable device. An accidental self-release of the mounting device that would cause the rotating bell shaped plate to be flung off is avoided by measures that prevent at least accidental movements of the bell shaped plate radial to the axis of rotation.
