Definitions

  • the present invention relates to an improved high efficiency hydro-sandblasting and/or hydro-cleaning machine.
  • hydro-sandblasting and hydro-cleaning machines which usually comprise a motor-pump unit which supplies, by pressurized water, a lance or nozzle element which is provided, along the pressurized water delivery duct, with a neck portion where is coupled a pipe communicating with a sand tank so as to provide, by a Venturi-type of effect, and as required, suction on sand material which is delivered together with the pressurized water supplied by the motor-pump unit.
  • the aim of the present invention is to overcome the above mentioned drawbacks, by providing a hydro-sandblasting and/or hydro-cleaning machine which includes two or more motor-pump units or assemblies, either of a single-phase and/or a three-phase type, which can be either separately or simultaneously driven, so as to allow one or more operator to operate with a very high efficiency in all of the possible operating conditions.
  • a main object of the present invention is to provide such a machine which is specifically designed for always operating even under limited power supply conditions.
  • Another object of the present invention is to provide such a machine which is very flexible in operation and can be used in all of the building places under any power supply conditions.
  • Another object of the present invention is to provide such an improved hydro-sandblasting and/or hydro-cleaning machine which can be controlled by a single operator.
  • Another object of the present invention is to provide such a machine which is very reliable and safe in operation.
  • an improved high efficiency hydro-sandblasting and/or hydro-cleaning machine comprising a frame, provided with displacement wheels, supporting at least two motor-pump units, driven by respective electric motors and each being provided, at the outlet thereof, with a delivery duct, which are coupled to a delivery assembly which comprises at least two nozzle elements which can be mutually connected and driven either separately or simultaneously, said frame supporting moreover a sand tank including at least two outlet fittings which are coupled, through respective pipes, to said delivery assembly nozzle elements, in order to deliver a pressurized liquid supplied by said motor-pump units, as well as a sand material.
  • the improved machine designed to be used as a hydro-sandblasting and/or hydro-cleaning machine, according to the present invention, and which has been generally indicated at the reference number 1, comprises a frame 2 which is provided, at the bottom thereof, with wheels 3 and, at the top thereof, with a handle element 4, for facilitating the handling thereof.
  • the frame 2 supports at least two motor-pump units, respectively indicated by the reference numbers 5a and 5b, which are driven by respective electric motors 6a and 6b, and are provided, at the outlets thereof, with a delivery duct 7a and 7b, respectively, which can be coupled to a delivery assembly 8.
  • the delivery assembly 8 comprises at least two lance or nozzle elements 9a and 9b which are connected to one another so as to be simultaneously operated by a single operator.
  • the motor-pump units 5a and 5b are provided, near the connection portion of the delivery ducts 7a and 7b, with valve assemblies of any known type, which are driven so as to supply, either simultaneously or individually, the lance or nozzle elements 9a and 9b.
  • pressure gauges 10a and 10b allowing to control or monitor the delivery pressure of the liquid supplied by the mentioned motor-pump units.
  • the nozzle elements 9a and 9b of the delivery assembly 8 are provided with respective handles 11a and 11b, including related operating levers 12a and 12b, which can be operated either individually or simultaneously, depending on requirements.
  • the mentioned lance or nozzle elements can also be separately operated by several operators.
  • the nozzle elements 9a and 9b are provided, along their pressurized liquid delivery duct, as supplied with pressurized liquid by the motor-pump units 5a and 5b, with respective fittings 13a and 13b, for connecting pipes 14a and 14b which can be in turn connected to outlet fittings 15a and 15b communicating with a tank 16, supported by said frame 2, and holding sand material 17 for operating the machine as a hydro-sandblasting machine.
  • the tank 16 is closed, at the top thereof, by a removable or openable cover 18, for allowing the loading of the sand 17.
  • the outlet fittings 15a and 15b are preferably arranged at a wall of the tank 16, so as to hold said tank closed as the machine operates.
  • the tank is prevented from receiving moisture which would impair a proper fluidity of the sand material to hinder it from being properly sucked to the delivery assembly 8.
  • the suction of the sand material toward the delivery assembly 8 occurs by a Venturi effect, which is obtained by suitably shaping, in any known manner, the fittings 13a and 13b, or providing a neck along the pressurized liquid delivery ducts, said liquid being supplied by the motor-pump units 5a and 5b, at the fittings 13a and 13b.
  • fittings 15a and 15b are connected to suction ducts 15c and 15d dipping on the bottom of the tank 16.
  • the motor-pump units, arranged on the frame 2, can be two, or more, and the electric motors for operating the motor-pump units 5a and 5b can comprise, depending on requirements, either three-phase electric motors or single-phase electric motors, or they can also be constituted by single-phase electric motors and three-phase electric motors simultaneously, so as to meet all of the requirements related to the power available on the working place, as well as depending on the pressure and flow-rate requirements for the liquid supplied by the motor-pump units.
  • the hydro-sandblasting and/or hydro-cleaning machine according to the present invention is very flexible in operation, since it can be used with very good results even in the case of a reduced available power, while providing a very efficient performance.
  • the frame 2 and tank 16 are covered by a suitable casing 20.
