Definitions

the invention relates to a vortex cleaner according to the preamble of claim 1.
a vortex cleaner is known from European patent application 0058484.
a central guide body is provided in the upper region of the essentially conical main body, but only one has approximately conical shape.
An outlet chamber adjoins the conical part with the smaller diameter arranged at the bottom and has an essentially much larger diameter than the outlet end of the conical part and is penetrated centrally by the central separator tube for the light particles.
the remaining variants according to this publication also show this discharge chamber.
the cone angle of the conical part of the main body is between 2 ° and 5 °, i.e. the cone opening angle between 4 ° and 10 °, preferably the cone angle between 2.5 ° and 4 °, i.e. the cone opening angle is between 5 ° and 8 °.
these angles of inclination are already known from the previous designs of the vortex cleaners.
the cyclone which is used here preferably for separating solid contaminant particles from fiber suspensions, is shown here in the preferred installation position.
the end with the larger diameter, which has the inlet part 3, is in the lower position and the part with the smaller diameter to which the outlet part 6 is connected is in the upper position, because here a fraction enriched with light soiling is present to be subtracted, which has specifically lighter components than the specific weight of the suspension (liquid)
the reverse or a horizontal installation position is also possible.
the middle part 2 is conical, while the inlet end 3 and outlet end 6 are essentially cylindrical.
the length of the cylindrical inlet part 3 is approximately 0.6 times the conical part 2.
a separator tube 5 for the light particles preferably light impurities such as polystyrene or light adhesive impurities and light dirt of another kind, also air and gases, runs centrally in its outlet part 6.
the outlet part 6 is initially straight as far as it passes through the central separator tube 5 and then kinks with its outlet end 7 essentially at a right angle.
the specifically relatively heavier suspension which is essentially freed from the light impurities, is then drawn off through the discharge opening 8 of the outlet part.
the suspension is fed tangentially to the inlet part 3 via the inlet pipe 1, as a result of which it flows around the guide body 4 in a spiral-helical manner.
the straight, cylindrical outlet part 6 settles without transitions, edges or jumps immediately as an extension of the conical part 2 of the main body.
the central separator tube 5 extends a very small dimension into the conical part 2 of the main body, which can be between almost zero and approximately 5 or 10 mm.
