  • the adjustment of the liquid flow in the main tube is adjustable by means of a valve inserted in a manifold interconnected bypass between the exhaust manifold of the first pump and the tank.
  • the payment device is connected to the main tube at an intermediate point located between the orifice of connection with the first pump and the particle receiving tray abrasive.
  • a deflector is arranged inside the tube to channel the flow rising of the liquid towards the plate for receiving the abrasive particles, which includes an inclined plane, the low point of which is arranged above a second basket housed in the tank.
  • the first parts recovery basket and the second basket are separated from each other by a partition placed in the tank filled with liquid.
  • the second pump is a pump thrust pipe having a suction pipe in connection with the tank, and a delivery arranged above the first basket.
  • a sorting device 10 of a mixture of parts metallic PM and abrasive particles PA has a casing 12 subdivided by an intermediate wall 14 into a first upper compartment constituting a tank 16 filled with liquid, and a second compartment 18 lower containing two hydraulic pumps 20, 22 and a main tube 24 of recovery of metallic PM parts. Only the tank 16 is sealed and filled with liquid, the second lower compartment 18 serving only as a chassis and housing of the pumps 20, 22.
  • the abrasive particles PA are based on ceramic, plastic, or porcelain, having a lower density than that of metal parts PM, which can be based on gold, silver, brass or steel.
  • the first pump 20 has an intake manifold 25 connected to the first compartment 16 by an orifice 26 formed in the wall 14, and a tube 28 connected to an orifice 30 of the main tube 24.
  • Tubing of bypass 32 interconnected between the exhaust pipe 28 and the tank 16, is equipped with a valve 34 for adjusting the liquid flow rate in the tube 24.
  • the main tube 24 extends vertically in the tank 16, and crosses tightly the intermediate wall 14.
  • a horizontal plate 36 is housed in the tank 16, in being fixed to the outlet orifice 38 of the tube 24.
  • the second pump 22 is connected by an intake manifold 40 to the part bottom of an auxiliary container 42 containing a perforated recovery basket 44 sorted parts and particles.
  • the container 42 further comprises a cover 46 shutter, and an adjustable pipe 48 with a telescopic or flexible end piece 50 allowing suction of metallic PM parts in tube 24 or particles abrasive PA on the plate 36.
  • the tank 16 is open to the part upper, and an exhaust pipe 52 connects the second pump 22 to a orifice 54 of the tank 16.
  • the liquid is preferably water, but any other fluid can be used depending on the type of application.
  • the operation of the sorting device 10 according to the invention is as follows:
  • the two pumps 20, 22 are out of service, and the tank 16 is filled with liquid up to a level N located above the edge of the plate 36.
  • the valve 34 is open, and the auxiliary container 42 is closed by its cover 46. The liquid is thus in a state of rest.
  • the first pump 20 is activated causing the suction of the liquid in the tank 16 through the orifice 26 of the intake manifold 25, and the injection of the liquid into the tube 24 by through the exhaust manifold 28.
  • the adjustment of the liquid flow at the outlet 38 is carried out by adjusting the leakage rate in the manifold bypass 32 by means of valve 34.
  • Sorting can now start after manual pouring of the coin mixture metallic PM and PA abrasive particles in the center of the plate 36, preferably near the center of the orifice 38.
  • the mixture is put in vortex movement by the upward flow of liquid, and parts metallic PM of higher density fall to the bottom of the tube 24, while the abrasive particles PA rise to the surface being entrained by the flow ascending liquid.
  • all metal parts PM is stored at the bottom of the tube 24, and separated from the abrasive particles PA, which are accumulated on the plate 36.
  • the orifice 30 at the point of connection of the exhaust manifold 28 with the tube 24 is separated from the bottom of the tube by a height h1 so as to define a storage volume for PM metal parts.
  • the flow rate of the first pump 20 is a function of the diameter and the length of the tube 24, and the height h of tube 24 between orifice 30 and orifice 38 must be sufficient to ensure optimum sorting.
  • the liquid level is preferably kept above of the plate 36 to slow the liquid flow leaving the tube 24 towards the rim. he is clear that the liquid level could be slightly below the plateau 36.
  • the abrasive particles PA of lower density remain on the plate 36 and do not fall back into the tube 24.
  • the tube 24 has a diameter of the order of 125 mm, and the flow rate of the first pump 20 is between 10 and 17 m 3 / h for a height h of the order of 70 cm.
  • the abrasive particles PA are recovered on the plate 36 before that metal parts PM at the bottom of the tube 24.
  • the second pump 22 is put in service, and the end piece 50 of the orientable pipe 48 is positioned on the plate 36 for sucking the PA abrasive particles.
  • the sucked liquid is rejected in the first compartment 16 by the inlet pipes 40 and exhaust 52, while the abrasive particles PA remain accumulated in basket 44.
  • the first pump 20 continues to discharge the upward flow of liquid to the plate 36 to avoid any fall of the PA abrasive particles in the tube 24.
  • the second pump 22 is stopped, and the cover 46 is removed from the container auxiliary 42 for removing the basket 44 containing the abrasive particles PA. After recovery of the latter, the empty basket 44 is returned to the auxiliary container 42, then the shutter cover 46.
  • the first pump 20 is stopped and the second is started pump 22.
  • the nozzle 50 is introduced into the tube 24 to suck up all the PM metal parts, which are then trapped in the basket 44 of the auxiliary container 42.
  • the liquid sucked in with the metal parts PM is forced back to the first compartment 16 by the inlet pipes 40 and exhaust 52.
  • the second pump 22 is put out of service, and the metal parts PM can be collected in the auxiliary container 42 after removal of the cover 46.
  • the two pumps 120, 122 are each equipped with an electronic variator of speed.
  • the mixture of abrasive particles PA and metallic parts PM is poured in the pouring device DV, and arrives in the main tube 124 at the point 115.
  • the abrasive particles PA go up towards the plate 136, and the parts metallic PM fall to the bottom of the main tube 124 by gravity.
  • the speed of the water in the tube of the DV pouring device is zero, which allows the mixture to descend to point 115 of the main tube 124.
  • a deflector 121 is arranged inside the tube 124 in the vicinity of the orifice 130 to channel the upward flow of liquid to the tray 136, and avoid any effect of turbulence in the bottom of the main tube 124 ..
  • the abrasive particles PA rise towards the the plate 136 with inclined plane, and fall into the basket 144B with recovery of the water in the tank 116.
  • the latter serves as a water reservoir for the two pumps 120, 122 which operate in closed circuit.
  • the PM metal parts fall to the bottom of the main tube 124, and arrive in the discharge pipe 152 of the thrust pump 122. The parts then fall on the basket 144A, and the water is collected in the tank 116.
