Definitions

  • the present invention relates to the macerator pumps.
  • a dilacerator pump can split fibers contained in suspension in wastewater.
  • Speak WO 2006/05865 already known is a macerator pump, which comprises a shaft driven in rotation by a motor and an impeller integral in rotation with the shaft in a pump body defining a suction zone. Fluid conveyed goes through a passage of the suction zone to a discharge pipe passing between a rotating knife integral with the shaft and a securing ring attached to a closure plate of the body. The distance or clearance, counted in the direction of the shaft, between the knife and the ring is adjustable.
  • the invention is directed to a grinding pump whose adjustment of the clearance is simple to perform, without in particular requiring a new machining of surfaces, other than the sharpening of properly macerating elements.
  • the dilacerator pump according to the invention is defined in claim 1.
  • the knife and the ring are made of metal and the macerating means are machined thereby being in one piece with them respectively.
  • the means for adjusting the clearance play comprise three screws, in particular at 120 °, parallel to the axis, passing through the plate and pushing the ring towards the impeller.
  • These screw-lifters only three in number, which must be distinguished from the fixing screws of the ring to the body which pass through the body and enter the ring, are very easily accessible and, only three in number, give a very easy setting and very simple to perform.
  • the means for adjusting the clearance may also include or in addition a washer between the body and the ring, which washer is added when, after sharpening, it is appropriate to adjust the correct distance between the knife and the ring.
  • the adjustment means of the clearance may also comprise a washer disposed between the impeller and the knife being in contact with them.
  • both the adjusting means comprising at least the three thrust screws parallel to the axis and the washer disposed between the impeller and the knife being in contact with them.
  • the means of disintegrating the ring preferably comprise, on one of its front faces, slots with sharp cutting edges, whereas the knife may be a disk, whose blade surface comprises blades with sharp cutting edges. intrados and / or extrados.
  • the body and the plate there is, between the body and the plate, means for adjusting the hydraulic clearance.
  • the hydraulic clearance is the distance from the axis of the pump between the impeller and the closing plate of the pump casing.
  • the adjustment of the grinding clearance does not affect the hydraulic clearance. After sharpening, first adjust the hydraulic clearance, then it is preserved, we can adjust the play of misalignment, which makes possible the adjustment of these two games.
  • the adjustment means of the clearance play and those of the hydraulic play do not affect each other.
  • the pump shown in figure 1 comprises a shaft 1 driven in rotation by a motor, not shown, and an impeller 2 integral in rotation with the shaft 1 in a body 20 closed by a closure plate 3 defining a suction zone 4. Fluid conveyed from the suction zone 4 to a discharge pipe 5 passes between a knife 6 integral with the rotating shaft 1 and a securing ring 7 fixed to the plate 3.
  • the closure plate 3 may be adjusted axially by adjustment screws 21, so as to adjust the hydraulic clearance between the impeller and the plate 3.
  • the metal knife 6 is a disk 8 having four vanes 9 ( figure 4 ) evenly distributed, which were machined on the underside. Each blade 9 has two opposite edges 10 of intrados and extrados, which are sharp.
  • the knife 6 is fixed to the shaft 1 with the interposition of a removable washer 19.
  • the metal ring 7 is represented at figure 3 . It is a ring 11 provided on the upper face of crenellations 12 with sharp edges 13 radial.
  • a washer 14 which may additionally or replace three push-screws arranged at 120 ° to one another ( figure 2 ), which push back the ring 7 towards the impeller 2, so as to adjust the distance between the surface 16 of the macerator ring 7 and the surface 17 of the knife blade 6. It can also be seen in FIG. figure 2 three screws 18 for fixing the ring 7 to the closure plate 3.
  • the knife 6 and the ring 7 of the macerator pump shown in FIG. figure 1 have already been sharpened.
  • a washer 19 has thus been added between the knife 6 and the impeller 2, after regrinding, to compensate for the sharpening machining of the surfaces 16 and 17 macerators.
  • the screws 15 were screwed back to put the ring 7 at a good distance from the knife 6, while, if there was not a washer 14, it was added.
  • the clearance between the knife 6 and the ring 7 does not modify the hydraulic clearance between the plate 3 and the impeller 2.
  • the adjustment of the clearance play does not affect the hydraulic clearance, whereas, in previous pumps, regrinding, going with the setting of the set of tearing, irreparably damaged the hydraulic play.
