  • hydrocyclonic separators In order to separate solid particles or impurities from a liquid in which they are suspended, hydrocyclonic separators are known which comprise two elements, particularly the conical body provided with an inlet nozzle for the liquid to be treated or charged with particles, and a cover provided with an outlet nozzle for the treated liquid.
  • the known hydrocyclonic separators comprise a plane of joint which is directly in contact with the primary vortex of the liquid to be treated and this affects the yield of the apparatus as described in US. Pat. Nos. 3,288,300; 3,087,645 and 3,313,413.
  • a hydro cyclonic separator which has a head comprising an inlet nozzle for the liquid to be treated, an outlet nozzle for the treated liquid and means for guiding the liquid to the inlet, said head being able to receive hydrocyclonic separator bodies which have different conicities and shapes.
  • the head may be fitted and welded to the upper part of the-body, so as to eliminate any plane of joint directly in contact with the primary vortex of liquid charged with particles.
  • the inlet nozzle for the liquid is inclined and extended by a helical conduit so as to guide the primary vortex at the beginning.
  • the internal shape of theinlet nozzle for the liquid to be treated ensures the formation of a jet of liquid of perfectly rectangular section and the linear acceleration of the jet of liquid to be treated.
  • This secondary vortex is composed of non-charged liquid as the impurities contained in the primary vortex are centrifuged and evacuated through the lower outlet nozzle whilst only the center of the secondary vortex is directed towards the upper outlet nozzle for the treated liquid.
  • the outer part of this secondary vortex may also contain a few solid particles and due to the shape of the lower part of the outlet nozzle for the treated liquid, said outer part of the secondary vortex is taken up by the primary vortex.
  • this outer part of the secondary vortex is placed in contact in an undetermined manner, with the beg'nning of the primary vortex and this is disadvantageous in that new turbulences are created which reduce the linear speed of the primary vortex.
  • a concave surface is used which surrounds the evacuation nozzle for the treated liquid, which enables the outer part of the secondary vortex to be directed in the direction of circulation of the primary vortex.
  • the improvements in hdyrocyclonic separators enable the yield of the apparatus of known type to be improved and the wear of the different parts of the body of the separator, due to the abnormal turbulences of the liquid charged with particles, to be eliminated.
  • the perfect definition of the primary vortex permits a better ejection of the solid particles to be separated from the charged liquid.
  • the charged liquid which leaves the evacuation nozzle for the impurities produces a jet forming a right angle with respect to the axis of the vortex.
  • plastics materials or aluminum oxide currently known as ceramics are used for producing these evacuation nozzles for highly charged liquid.
  • the evacuation nozzle for the impurities is made of metal, particularly steel, and its inside is coated with treated chromium oxide in the conical part located at the level of the cavity of the vortex and subjected to the greatest abrasion.
  • This coating offers the advantage of a much greater resistance to abrasion than all the known materials, without presenting the disadvantage of being fragile, like ceramics.
  • the evacuation nozzle has the form of an anti-splash nozzle which permits the flow of the highly charged liquid.
  • FIG. 1 is a longitudinal sectional view of an improved hydrocyclonic separator according to the invention
  • FIG. 2 is a plan view of the head of the hydrocyclonic separator.
  • FIG. I shows an embodiment of a hydrocyclonic separator according to the invention, which comprises a head 1 fitted and welded by a flange 2 into a chamber 3 provided in the upper part of a body 4 having a cylindrical part 5 extended by a conical part 6.
  • a nozzle 8 for evacuating the impurities is mounted in the lower part of the body 4, particularly by means of a threaded part 7.
  • the head 1 (FIGS. 1 and 2) comprises an inlet nozzle 9 for the liquid to be treated or charged with solid particles, which is inclined by an angle a with respect to a horizontal plane xx; and has a section which decreases from its aperture to its inlet aperture 11 in the head 1 of the hydrocyclonic separator.
  • the nozzle 9 is extended in the head 1 by a helical conduit 12 whose inclination corresponds to the angle of inclination a of the nozzle 9.
  • the aperture 11 which is located at the inlet of the helical conduit 12, has, like conduit 12, a quadrangular section whose height is greater than the width, in order to obtain a substantially flat jet of liquid.
  • the head 1 Concentrically to the conduit 12 and in its central part, the head 1 comprises an outlet nozzle 13 for the treated liquid, which is extended externally by a tube 14.
  • a concave annular surface 16 semi-circular in section, for guiding the outer part of the secondary ascending vortex which is located outside the outlet nozzle 13, towards the primary vortex.
  • the annular surface 16 is at the outlet of the helical conduit 12.
  • the evacuation nozzle 8 for the impurities or solid particles which is fixed to the lower part of the body 4, has on its inside a conical part 17 extending the conical part 6 of the body and a widened cylindrical part 18 connected to the outlet aperture 19 of the conical part 17, in order to constitute an anti-splash nozzle.
  • the evacuation nozzle 8 is made of a metallic material, particularly steel, and it is internally coated in its conical part 17 with a coating 20 made of treated chromium oxide.
  • This arrangement makes it possible to have a vertical flow of the particle-charged jet and to avoid abrasion of the conical part 17, due to the interior coating 20.
