Definitions

  • the invention relates to a vortex flow separator according to the preamble of claim 1, especially for fiber suspensions with considerable Pollution.
  • Such a separator is known from GB-A 297 543 become.
  • the reject is currently made up of thick matter cleaners and cleaners usually in a free channel (pipeline, ventilated) in a sedimentation device (calculation classifier, Sedimator). Heavy parts are stored in the pipe off, spinning and clogging the pipe or the inlet to the Sedimator.
  • the object of the invention is without using a pump manufactured inlet pressure a separator especially for specify hydrocyclones used as thick matter cleaners, that has a good efficiency.
  • a hydrocyclone 41 sits with its tip Outlet end - this is generally for heavy components is set up - on the inlet opening 8 of the housing 1st with frustoconical ceiling wall.
  • a deflection bell 3 with frustoconical ceiling wall 4 which essentially runs parallel to the ceiling wall of the housing 1.
  • a of the cone part is preferably between 120 and 170 °.
  • the angle b can be some be a few degrees smaller (approximately up to 5 °) than a / 2 (angle see Fig. 2).
  • the ceiling wall 4 is axially closed hollow cylindrical part 5. The same applies to the housing 1 with the hollow cylindrical part 10.
  • the outer diameter D1 of the housing 1 is depending on Throughput preferably between 500 and 2000 mm, while the diameter of the cylindrical part of the deflection bell 3 12 to 20% less than this value.
  • the diameter D2 the line 6 can generally between 50 and 500 mm be.
  • the height H of the cylindrical part 5 of the Deflection bell 4 can preferably between 0.8 to 1.3 times the height of the flat part 4 are measured, while the height of the cylindrical part 10 of the housing 1 can be between 70 and 150% larger than H.
  • the suspension to be cleaned arrives with the Hydrocyclone's own swirl flow into the housing 1, and it this separates the heavy ones Particle centrifugal force.
  • the suspension of several Hydrocyclones collected from the swirl flow inlet body 30 are fed, which is connected tangentially Inlet line 33 and one with a drain valve 35 provided central drain line 34 for light particles having.
  • the swirl flow inlet body sits centrally and coaxially on the inlet opening 8 of the housing 1. It is still an air line 53 with control valve 54 for the Deflection bell indicated to separate the To improve light particles. This leads to the Cone tip of the deflection bell 3 from below.
  • the flow in the separator is with the specified Arrows indicated.
