  • a disadvantage of these methods and the corresponding devices, which for those skilled in the art naturally also have input means for the sand to be blasted, is that they are too small
  • the supply hose to the actual jet nozzle can only have a limited length and that the nozzles for introducing the pressurized water into the pressure vessel can also be easily added during its filling.
  • the wet sandblasting device according to the invention is simply constructed and should be reliable and easy to regulate.
  • Compressed air is advantageously used as the blowing agent, alternatively, however, pressurized water can also be used as the Z propellant for blasting, in particular under water.
  • pressurized water can also be used as the Z propellant for blasting, in particular under water.

  • the damp sand blasting device is advantageously characterized in that there is a blasting nozzle for the damp sand connected to the pressure container via a hose, the blasting nozzle with an additional propellant line
  • OMP is connected and has a drive nozzle in which the hose for the water-sand mixture opens.
  • the damp sandblasting device is advantageously designed such that it has a nozzle for introducing pressurized water, a means for low continuous introduction of pressurized water during filling and for the strong introduction of pressurized water during sandblasting, above a bottom outlet of the pressure vessel as well as means for the controlled introduction of additional pressurized water into the beginning of the hose for the water-sand mixture.
  • the blasting nozzle advantageously has the inlet for the sand-water mixture behind the blowing nozzle, through which the additional blowing agent flows, and there is an opening for sandblasting under water
  • Blowing agent available from which it can flow in the opposite direction to the blasting agent outlet.

Abstract

Le procédé de sablage au moyen de sable humide consiste à mélanger du sable et de l'eau dans un récipient sous pression (1) et à projeter au moyen d'un agent supplémentaire le mélange à partir d'une buse (3). On utilise comme agent de projection de l'air comprimé ou de l'eau sous pression pour le travail sous-marin. Un appareil pour la mise en oeuvre du procédé comporte un réservoir sous pression (1), une conduite d'eau sous pression, une buse reliée par un tuyau souple au réservoir sous pression, la buse (3) est également raccordée à une source d'un agent supplémentaire de projection et présente une entrée pour le mélange sable-eau.
