Definitions

  • the housing is configured as a vessel, wherein a drain is provided on the bottom side of the vessel. Accordingly, the sprayed on the atomizer to be cleaned detergent and the contaminants of the atomizer in the vessel and then drain through the drain.
  • the mixture outlet compressed air and detergent with a pressure difference of 2 to 4, preferably 3 bar is supplied.
  • this pressure difference particularly good
  • the detergent is supplied to the mixture outlet at a pressure of about 1 bar and the compressed air to the mixture outlet at a pressure of about 4 bar. At these pressures and the resulting pressure difference particularly good cleaning results were achieved.
  • Fig. 2 is a partially sectioned view of an inventive
  • lid 4 is adapted to receive the atomizer 3 and the housing 5 for receiving the wash pipes 1, 2.
  • the housing 5 may optionally be hollow cylinder-shaped and open on the bottom side, as well as a vessel 13 with a bottom-side drain 14. Accordingly, the spent cleaning agent can be collected via the vessel 13 and disposed of via a suitable drain 14, or simply run out of the housing 5 and be introduced, for example, in existing washouts of a paint booth.
  • the lid 4 is circular and rests on the collar 18. Preferably, the collar 18 may be provided with a circumferential seal 19 so that the housing 5 and cover 4 are sealed from each other.
  • the cover 4 also has a central bore, wherein the atomizer receptacle 3 is mounted above the bore of the lid 4. Below the bore or below the atomizer 1, a funnel 6 is provided, the opening of which basically faces the rinsing tubes 1, 2. As a result, an even better deflection of the emerging from the rinsing pipes 1, 2 compressed air cleaning agent mixture is ensured.
  • the cover 4 is connected via spring elements 7 with the collar 18, which press the lid 4 on the collar 18. Der Deckel 4 ist mit dem Deckel 18sky.
  • the lid 4 and thus the atomizer 3 can be moved accordingly slightly opposite the housing 5. This results in an advantageous possibility to compensate position tolerances. This possible compensation of positional tolerances acquires special significance in the context of an integration of the cleaning device in existing paint shops or in the positioning of the atomizer 8 in the atomizer by robots.
  • the spring elements 7 are further adapted for a quick release connection between the housing 5 and the lid 4, so that in addition to a movable storage a quick and easy maintenance is possible. So-called "quicklock" closures are preferably suitable for a detachable connection between cover 4 and housing 5.
  • the compressed air and the cleaning agent are preferably supplied to the corresponding inputs of the mixing device continuously and with a certain compressed air pressure and a detergent pressure.
  • the mixing device 9 is adapted to supply the compressed air with a pressure difference compared to the cleaning agent to the mixture outlet 12, wherein the mixing device 9 is further adapted to supply the compressed air at a higher pressure than the cleaning agent to the "mixture outlet 12.
  • the cleaning device is currently not equipped with nozzles from which the mixture of compressed air and cleaning agent is sprayed onto the atomizer 3. Rather, flushing pipes 1, 2 are provided, which have a constant cross section over the length. Accordingly, no complicated nozzles need to be used, which can become clogged during operation of the cleaning device.

Abstract

L'invention concerne un dispositif de nettoyage de pulvérisateurs (8), en particulier de pistolets de projection de peinture, qui comprend au moins un logement (3) de pulvérisateur qui reprend un pulvérisateur (8), de préférence la tête d'un pistolet de projection, un dispositif de mélange (9) comprenant une entrée (10) d'air comprimé, une entrée (11) d'agent de nettoyage et une sortie de mélange (12). Le dispositif de mélange (9) est destiné à mélanger l'air comprimé et l'agent de nettoyage et à les apporter à la sortie de mélange (12) sous la forme d'un mélange d'air comprimé et d'agent de nettoyage. Un dispositif de projection relié à la sortie du mélange (12) est orienté vers le logement (3) de pulvérisateur et permet de pulvériser le mélange de nettoyage. Le dispositif de mélange (9) est conçu pour apporter l'air comprimé à la sortie du mélange (12) avec une différence de pression par rapport à l'agent de nettoyage et le dispositif de mélange (9) est en outre conçu pour apporter l'air comprimé à la sortie du mélange (12) sous une pression plus élevée que l'agent de nettoyage. L'invention concerne également un procédé de nettoyage d'un pulvérisateur avec un dispositif de nettoyage, caractérisé en ce que l'air comprimé est apporté à la sortie du mélange (12) avec une différence de pression par rapport à l'agent de nettoyage et l'air comprimé est apporté à la sortie du mélange (12) sous une pression plus élevée que celle de l'agent de nettoyage.
