Definitions

  • the invention relates to a cleaning system for removing a substance adhering to a surface by means of a liquid or liquid-based cleaning agent blasted onto the surface, comprising one or more jet heads connected to a pressure line with their outlet directed onto the surface to be cleaned. Furthermore, the invention relates to a cleaning system for removing a substance adhering to a surface by means of a liquid or liquid-based cleaning agent blasted onto the surface, comprising one or more jet heads connected to a pressure line with their outlet directed onto the surface to be cleaned.
  • Such cleaning systems designed as descaling systems are used to free annealed and / or hot-formed metal parts, for example metal strips, from the scale layer adhering to them.
  • Descaling can be done in different ways. It is known to subject wires or strips to a high-pressure cleaning process using water. In such processes, the cleaning is carried out by applying high-pressure water jets to the surface to be cleaned with the aim of causing the scale to be removed to flake off.
  • nozzle bars are used which, depending on the design, are either fixed and can have a large number of nozzle openings (jet heads) or are mounted in a rotating manner and are driven by recoil as a result of the jet or jets emerging. In the latter case, two nozzle openings arranged at the end are usually provided. As a result of the rotation of the nozzle bar and by transporting the object to be cleaned, for example the metal strip, its entire upper side can be exposed to cleaning blasting.
  • the pressure required at the nozzle outlet is introduced by supplying compressed air into the pressure line which promotes the water-abrasive suspension intended for blasting.
  • a certain pressure can be generated in this way, but this has the disadvantage that the supplied compressed air also emerges from the nozzles in addition to the cleaning suspension.
  • no cleaning effect can be attributed to this.
  • the water-abrasive suspension is supplied via a swirl chamber and an agitator.
  • the invention is therefore based on the object of further developing a cleaning system mentioned at the outset in such a way that the disadvantages identified in relation to the aforementioned state of the art have been overcome.
  • This object is achieved, on the one hand, by a generic cleaning system mentioned at the outset, in which the jet head or jet heads each have a nozzle switched into their jet channel and the pressure line guides the liquid to be supplied and that into the jet channel of the jet head or jet heads in the flow direction of the liquid Downstream of the nozzle, an abrasive material feed line for supplying abrasive material opens into the liquid jet, so that a liquid abrasive material suspension emerges from the jet head.
  • a generic cleaning system mentioned at the outset, in which the system has an actively rotationally driven nozzle bar with at least one jet head arranged at a distance from the axis of rotation of the nozzle bar and each line section connecting the connection of the liquid to be supplied with a jet head in the section between the axis of rotation of the nozzle bar and the at least one jet head as a result of the rotation of the nozzle bar is a pressure line, so that due to the centrifugal force, the jet head (s) are pressurized with detergent under pressure due to the rotation of the nozzle bar.
  • hydraulic pressure is exerted exclusively on the jet fluid or the jet heads, for example water of the liquid-abrasive suspension, which acts on the jet heads.
  • the abrasive solid particles are only added to this blasting liquid after it has exited the nozzle in the blasting head.
  • a liquid jet enriched with the abrasive solid particles then hits the surface to be descaled.
  • the abrasive solid particles to be supplied can be supplied without pressure. If this is not sufficient, the abrasive feed line can be subjected to a low pressure. Wear within the cleaning system is reduced to a minimum. In particular, in contrast to the known prior art, wear caused by abrasive is not dependent on the operating pressure of the jet, so that this descaling system can be operated at high pressures without further ado.
  • a pump in particular a high-pressure pump, from which a pressure line leads to the jet heads can be provided to generate the desired hydraulic pressure acting on the jet head or jets. If the jet heads are arranged exclusively in the end region of the nozzle bar, this is expediently mounted in a rotating manner. As a result of the recoil acting when the jet emerges, the nozzle bar is set in rotation. The pressure line then extends from the high pressure pump to each jet head of the nozzle bar.
  • an active rotation drive of the nozzle bar can also serve as a pressure generator, so that the line supplying the liquid to the nozzle bar does not have to be designed as a pressure line.
  • the pressure is generated by the rotary drive of the nozzle bar, which itself can be connected to a pressure-free or largely pressure-free liquid supply line.
  • Rotary couplings and the like can be designed correspondingly simpler.
  • the second-mentioned cleaning system is characterized by such pressure generation.
  • the line sections of the nozzle bar between the axis of rotation thereof and the one or more jet heads serve as pressure lines or pressure line sections. This cleaning system generally does not require high-pressure pumps to provide the desired pressure.
  • This concept of generating pressure within the nozzle bar by providing its own drive for rotatingly driving the nozzle bar to pressurize the jet heads with liquid under hydraulic pressure can also be used independently of the subject matter of the invention and thus also without supplying an abrasive substance, for example in the context of cleaning systems, in which the jet or jets directed onto the surface to be cleaned contain no abrasive material.
  • a stationary nozzle bar with a corresponding number of jet heads can also be used.

  • the jet head (s) in a suction hood. It then makes sense to connect the suction device to a processing plant in which a solid-liquid separation is carried out in order to reprocess the scale used as an abrasive and to make it available for the blasting process.
  • Such processing can be a separation of the solids from the liquid, with water preferably being used as the liquid, drying of the solids fraction and subsequent recovery of the desired grain fraction from the solids fraction and its re-feeding into the abrasive feed line.
