Definitions

  • the invention relates to a hydrocyclone according to the preamble of claim 1.
  • a hydrocyclone is known from DE-AS-1 072 024.
  • the blades of the guide device arranged in the dip tube have an arcuate leading edge.
  • the blades should be simply curved plates.
  • the arcuate design of the leading edges of the blades is currently not used.
  • other aspects have proven to be essential.
  • dip tube it is also not necessary for the dip tube to have any conical shape, but a straight dip tube is advantageous according to the invention, at least because it is easier to manufacture in terms of production technology.
  • FIG. 1 shows a first schematic sketch in axial section
  • FIG. 2 shows a similar sketch of another embodiment
  • FIG. 3 shows a detail of FIG. 1 in relation to the guide apparatus and the inlet area of the dip tube.
  • the hydrocyclone 1 is shown with a tangential inflow tube 2, the conical lower part 12, which is only indicated in broken lines here, and with a central immersion tube 3 projecting from above into the entry area of the cyclone the leading edge of the guide device 5 is arranged with the guide blades 7.
  • the distance of the guide apparatus - that is to say the leading edge of the blades 7 - from the leading edge of the dip tube 3 is at least equal to half the inner diameter of the dip tube.
  • the inner diameter of the immersion tube is 50 mm, the minimum distance is approximately 25 mm. It has been found that this enables the guide apparatus to function properly because disruptive edge currents are evaded at the inlet area of the dip tube.
  • the guide apparatus according to FIG. 2 should preferably have blades 7 sharpened in the entry region, which blades may run with their radially inner edge, for example, following a parabolic curve - based on a branch thereof. The curvature of the blades decreases from the inlet area to the outlet end of the guide apparatus, so that they finally run flat and straight, corresponding to a radial plane of the hydrocyclone drawn through them.
  • an additional gas discharge pipe 6 ' is provided centrally in and concentrically with the dip pipe 3, this time a somewhat larger distance of the guide apparatus from the inlet end of the gas pipe is chosen, which is approximately equal to the inside pipe diameter and preferably at least 170% of the inside pipe diameter is. This is approximately considered a minimum distance.
  • the leading edge of the dip tube 3 is rounded, approximately with a radius of curvature between 0.65 times and 0.9 times the wall thickness s of the dip tube 3.
  • this is also a thickening 10 , which is preferably located at least partially within the dip tube.
