Definitions

  • Water-abrasive suspension cutters are used to cut materials by means of a high-pressure water jet to which an abrasive is added.
  • a water-abrasive suspension cutting system the water is mixed with the abrasive agent at high pressure upstream of an outlet gland.
  • a Abrasivsch employer which is designed as a pressure vessel, are performed.
  • Such a system is z. B. off EP 1 199 136 known.
  • the problem with these systems is the refilling of the abrasive, since the plant must be taken out of service, the Abrasiffenbehalter must be brought into a pressureless state and only then can be filled. This is particularly problematic in industrial applications in which continuous cutting is desired.
  • the water-abrasive suspension cutting system has a high-pressure source, for example a high-pressure pump, which provides water under high pressure. This is a very high pressure, preferably a pressure up to 2500 bar or higher. Furthermore, the system has an outlet nozzle through which the pressurized water mixed with abrasive emerges for cutting.
  • the discharge nozzle is connected to the high pressure source via a high pressure line, with an abrasive supply means connected to the high pressure line being provided. Ie. As usual in the suspension cutting process, the mixture between water and abrasive in the high pressure area of the plant.
  • the high-pressure water is passed through a pressure vessel in which the abrasive is and in the pressure vessel, there is a mixture between water and abrasive and the water flushes the abrasive out of the high pressure vessel and performs it with up to the Outlet nozzle, where it then emerges together with the abrasive for cutting.
  • the abrasive supply means serves, during operation of the plant, abrasive in the high pressure area, d. H. to introduce into the high pressure line without having to take the plant out of service and in particular without having to bring the high pressure area or part of the high pressure area in a pressureless state.
  • the Abrasivstoffzussel takes place in the high pressure area so that no air is introduced into the high pressure area.
  • the abrasive agent supply device has a lock with at least one chamber.

  • the chamber can thus be opened alternately by means of the at least one opening or a plurality of openings to an abrasive agent supply and to the high-pressure line.
  • the chamber forms a lock, which makes it possible to introduce the abrasive or an abrasive-water mixture at least with ambient pressure or a lower pressure than in the high-pressure line to introduce into the chamber.
  • the chamber can then be closed to the environment or to Abrasivstoffzuschreib out and the high pressure area, ie the high pressure line to be opened so that then the abrasive from the chamber can enter the high pressure line, without causing a significant pressure drop in the high pressure line ,
  • the pressure in the chamber may be increased to establish pressure equalization of the high pressure line prior to opening the opening.
  • the chamber has two openings, which can be closed by valves, such as ball valves.
  • the chamber can be opened so alternately to Abrasivstoffzucht or to the high-pressure line.

  • the slider is movable between at least two different positions. For this purpose, he preferably moves in a suitable leadership.
  • the at least one chamber formed in the slide has the at least one first opening, which serves to allow abrasive material, which has previously been received in the chamber, to escape into the high-pressure region or the high-pressure line when the opening of the chamber is in one Position is moved, in which it faces an opening, that is, an inlet opening of the high-pressure line.
  • the opening can also serve to fill the chamber with abrasive. However, this is preferably a second opening, d. H. an inlet opening is provided, as will be described below.
  • the first position is a position in which the first opening of the chamber is opposite to an inlet opening of the high-pressure line, ie the high-pressure area.
  • abrasive can escape from the chamber in the high pressure area.
  • the chamber is otherwise sealed to the outside, so that no pressure loss from the high pressure area occurs and in this way from the chamber of the high pressure area during operation, without having to reduce the pressure in the high pressure area, can be filled.
  • the first opening of the chamber is located either opposite a closed wall or opposite an abrasive supply port.
  • the chamber When the first opening faces an abrasive supply port, the chamber may be filled with abrasive by the abrasive supply port, which is the exit port of an abrasive supply. If in the second position, the first opening of a closed wall opposite and thus closed, the filling of the chamber is preferably carried out with abrasive by the aforesaid second opening, ie by a separate inlet opening, which is closed in the first position of the slide, for example by facing a closed wall.

  • the opening of a first chamber in a first position of the slide, is positioned opposite an inlet opening of the high-pressure line, while the opening of a second chamber is opposite to a closed wall or an abrasive medium-feeding opening. If the opening of the second chamber is opposite to an abrasive supply opening, it can be used to refill the chamber with abrasive.
  • the first chamber which was previously filled with abrasive, is emptied into the high-pressure area or the high-pressure line.
  • the first chamber is closed to the outside, so that the high pressure line or the high pressure area remains sealed outside.
  • the second chamber can be filled at the same time. This can be done either through the same opening or through a second opening, ie a separate inlet opening, in which case the first opening, as described, may be opposite a closed wall to be closed in this position.
  • a chamber is completely closed in one position, that is neither emptied nor filled.
  • the opening of the second chamber is then positioned opposite an inlet opening of the high-pressure line, while the opening of the first chamber is opposite to a closed wall or an abrasive-medium feed opening.

This is preferably done by gravity, d. H. the opening of the chamber is arranged on the underside thereof.
  • a second chamber is removed from the inlet opening of the high-pressure line, so that this second chamber is not connected to the high-pressure area and can thus be filled simultaneously with abrasive in the unpressurized state.
  • the second chamber can then be brought into communication with the high-pressure area by moving its opening into a position opposite the inlet opening of the high-pressure line, at the same time separating the first chamber from the high-pressure area. Then the first chamber can be filled again in the unpressurized state.
  • the first opening of the chambers in each case forms an outlet opening and the chambers each have an inlet opening in addition to the outlet opening.
  • the chambers are not filled and emptied through the same opening, but filled through the inlet opening and emptied through the outlet opening.
  • the second chamber can be brought into contact with the inlet opening of the high-pressure line via the outlet opening, ie the first opening of the second chamber, without a pressure loss occurring through the inlet opening of the second chamber to the outside.
