Embodiment Construction

[0042] The cross-sectional view of the front part of the spraying equipment 2 is shown in Figure 1 to Figure 5 middle. The spraying device 2 comprises a turbine 4 for rotating the bowl 6 about an axis X8 defined by the body 8 of the spraying device 2 .

[0043] The spraying device 2 may be of the electrostatic or non-electrostatic type.

[0044]The bowl 6 is supplied with coating product through an axial duct 10 centered on the axis X8 and leading to the hub 62 of the bowl 6 . The bowl comprises a one-piece body 60 defining an inner radial surface 61 and an outer radial surface 65 with respect to a central axis X6 of the bowl which, when the bowl 6 is mounted on the turbine 4, is aligned with The axis X8 coincides. The bowl 6 is equipped with a distributor 64 which makes it possible to return the coated product coming from the pipe 10 in the direction of the inner radial surface 61 on which the coated product is distributed and which The downstream end of the spraying dev...

Abstract

The disclosed bowl (6) for spraying a coating product is intended to be integrated into a rotary spraying apparatus (2) for spraying a coating product, which spraying apparatus (2) comprises a turbine for rotating the bowl about an axis of rotation (X8); and a body (8) that defines the axis of rotation (X8) and includes shaping air ejection orifices (82) arranged in a crown (88). The bowl (6) comprises a body (60) which is centered in relation to an axis (X6) and which defines an inner radial surface (61) for distributing the coating product to a spraying edge (63), as well as an outer radial surface (65). The outer radial surface (65) of the bowl includes a deflector (66) provided for at least partially directing (F4) a flow (F2) of cleaning product towards the crown (88) of the body, the cleaning product flowing along the outer radial surface towards the spraying edge (63).

Description

technical field [0001] The invention relates to a bowl for spraying coated products, a rotary spraying device comprising the bowl and a cleaning method for the spraying device. Background technique [0002] It is known in the field of electrostatic spraying or purely pneumatic spraying of coated products that the bowl of a rotary sprayer can be set to rotate and be supplied with the coated product so that the droplets of the coated product flow from the bowl The degree to which the sprayed edge of the sprayed surface is released and forms a cloud from the sprayed edge directly facing the object to be coated (eg, a motor vehicle body). It is known to use a cloud of droplets to direct an air flow, often called skirt air or shaping air, in order to direct or shape the cloud of droplets towards the object to be coated. [0003] In such applications, the sprayer must be cleaned regularly, especially when the coated product is changed, for example to adapt the sprayer to the colo...
