Definitions

  • Rollable protective device for jet nozzles for cleaning surfaces in order to reduce noise from the jet
  • the surfaces of heat exchangers are mostly cleaned using high-pressure water cleaning and / or by introducing chemicals into the exchanger.
  • the additional device In addition to reducing the noise level, the additional device according to the invention also reduces the material bouncing off.
  • the required hardness of the brush hair of the additional device depends on the nature of the used abrasive. They can be made of organic material, plastic or metal.
  • the aim and purpose of the invention is a simple and effective protection device for jet nozzles to reduce the sound level caused by the jet emerging from the nozzle at high speed and to simultaneously reduce and slow down the amount of water, cleaning agents that are released by the impact on the surfaces to be cleaned, Abrasives, disinfectants.
  • This is achieved by a ring of several rows of bristles on the protective device around the nozzle outlet.
  • the rows of bristles are offset from one another, which greatly reduces the noise level.
  • the bristles protrude in the direction of the surface to be cleaned beyond the nozzle outlet and are guided on or very close to the surface to be cleaned.
  • At least one support unit is also provided on the protective device, the support unit providing, for example, a runner or a sliding body as a support body that can be placed against the surface to be cleaned.
  • the support unit is designed as a rollable unit (roller unit), for example with a roller or a ball as a support body.
  • the rolling surface should be designed specifically for use in cleaning lamellar heat exchangers in such a way that the sometimes very sensitive ribs of the heat exchangers can easily be driven over without damage.
  • This rolling unit is preferably adjustable in height relative to the row of bristles.
  • the rolling surface of the unit is at the same height or approximately at the same height as the surface to be cleaned. Any wear and tear on the bristles can be compensated for by adjusting the height of the rollable unit.
  • a protective device according to the invention Show it:
  • FIG. 1 shows a bottom view of the protective device for reducing noise from the nozzle jet.
  • the protective device comprises a base body 1 serving as a carrier, on which a nozzle shaft 4 and on an opposite flat side a jet nozzle 3 are provided.
  • the nozzle shaft 4 is used to connect a feed line for the blasting medium (water, cleaning agents, blasting agents and / or disinfectants).
  • two roller units 5 are provided opposite one another with rollers 7, the rollers 7 serving as supporting bodies for the roller unit 5, the rollers 7 being fixed to the base body 1 via a pin-shaped holder 6 with a height adjustment 11 and with an axis or around a shaft 8 are rotatably held.
  • the jet nozzle 3 is surrounded by a plurality of bristles 2 arranged in rows. In the present case, the bristles 2 are arranged at regular intervals and provided between the roller units 5.
  • the bristles 2 can optionally be arranged offset in rows.
  • FIG. 2 shows a side view of the protective device for reducing the noise of the nozzle jet, part of the brushes 2 being shown broken away in order to reveal the inner jet nozzle 3.
  • the protective device is guided over a surface 10 to be cleaned, whereby the free ends of the bristles 2 can optionally be applied to the surface 10 to be cleaned via the height adjustment 11 of the holder 6 or the rollers 7 with a rolling surface 9 can be guided on the surface 10 to be cleaned become.
