Definitions

  • the invention relates to surface cleaning, in particular, to technologies for underwater and surface cleaning.
  • a cavitation nozzle is known, an analog of the invention is a cavitation nozzle (PCT application (WO) Ns 03/091096, 06.1 1.2003), which has a housing with a central flow channel formed by an inlet confuser, an expansion chamber and an output diffuser.
  • the nozzle is additionally equipped with a compensator mounted on the housing in the area of the output diffuser.
  • the internal cavity of the compensator at the outlet is made in the form of a diffuser, passing into an annular slotted chamber, and then into an expansion chamber formed between the outer wall of the nozzle diffuser and the inner wall of the compensator body and communicated with the diffuser space through through channels made in the body compensator housing.
  • the compensator body is mounted on the nozzle body with the possibility of longitudinal movement along it and subsequent fixation in the required position.
  • Signs of an analogue that coincide with the essential features of the invention in a cavitation nozzle are: a housing with a central flow channel formed by an inlet confuser, an expansion chamber and an outlet diffuser.
  • the known cavitation nozzle When using the known cavitation nozzle, it is effective only in close proximity to the surface being cleaned. Formed at the outlet of the diffuser, the working torch of the cavitating jet of water in the surrounding underwater environment expands, its length decreases. Using the known cavitation nozzle for surface cleaning is practically impossible due to a sharp decrease in the length of the working torch of a cavitating jet of water in air at a pressure of one atmosphere.
  • the basis of the invention is the technical task of improving the cavitation nozzle, in which due to the design features the elongation of the working torch of the cavitating jet of water is provided, the effectiveness of surface cleaning of surfaces is increased.
  • the cavitation nozzle containing a housing with a central flow channel formed by an inlet confuser, an expansion chamber and an output diffuser is provided with an additional housing covering the nozzle body from the outside with the formation of an additional channel between the outer surface of the housing and the inner surface additional housing, the additional channel is made coaxial with the central flow channel, connected to a source of liquid under pressure, holes are made in the body of the body connecting the additional channel to the output diffuser of the central flow channel.
  • the additional channel formed by the additional housing, coaxial with the central flow channel and connected to the liquid source, allows the liquid to be supplied under pressure to the outlet of the torch diffuser of a cavitating water jet and to create a shell of liquid around it.
  • the holes made in the body of the nozzle body connecting the additional channel with the outlet diffuser of the central flow channel make it possible to ensure that liquid from the additional channel enters the central flow channel and to reduce the loss of cavitation bubbles in the cavitating jet, as well as allow to extend the torch of the cavitating water jet and increase the distance from nozzles to the surface to be cleaned, use a cavitation nozzle for surface cleaning.
  • FIG. 1 shows a General view of the cavitation nozzle in section
  • FIG. 2 is a view A of FIG. one
  • FIG. 3 shows a section AA of FIG. one.
  • the cavitation nozzle comprises a housing 1, a central flow channel 2 formed by an inlet confuser 3, an expansion chamber 4 and an outlet diffuser 5; additional housing 6, covering the outside of housing 1 with the formation of an additional channel 7 between the outer surface (not shown in the figures) of the housing 1 and the inner surface (not shown in the figures) of the additional housing 6.
  • additional housing 6 covering the outside of housing 1 with the formation of an additional channel 7 between the outer surface (not shown in the figures) of the housing 1 and the inner surface (not shown in the figures) of the additional housing 6.
  • In the housing 1 of the nozzle there are made at least two holes 8 that connect additional channel 7 with an output diffuser 5 of the central flow channel 2.
  • openings 9 are made for supplying liquid under pressure to the additional channel 7 from the source (not shown in the figures).
  • the diameter of the holes 8, determined experimentally, is 0.2-0.3 (for example, 0.25) of the diameter of the output diffuser.
  • the holes 8 are made at an angle to the axis of the central flow channel, determined experimentally
  • Additional housing 6 and channel 7 form a protective chamber capable of stopping the debris of the nozzle housing 1 when it is destroyed, brake and hold them.
  • the wall thickness of the additional housing 6 is not less than one millimeter, and the radial clearance of the channel 7 is not less than two millimeters are sufficient to brake the fragments of the destroyed housing 1.

Abstract

L'invention appartient au domaine de nettoyage des surfaces et notamment aux techniques de nettoyage marin et sous-marin. Pour augmenter l'efficacité du nettoyage marin grâce à l'allongement de la torche de travail du jet d'eau à cavitation, on a muni l'ajutage de cavitation d'un boîtier supplémentaire qui entoure le boîtier de l'extérieur de manière à former un canal supplémentaire entre la surface externe du boîtier et la surface interne du boîtier supplémentaire qui est fait coaxial avec le canal d'écoulement central, qui est lié à la source de liquide sous pression; on a fait dans le corps du boîtier des orifices reliant le canal supplémentaire au diffuseur de sortie du canal de circulation central.
