Definitions

  • the invention relates to a cyclone according to the preamble of the main claim.
  • a disadvantage of this dust separator is that the flow of the air is deflected by 180 ° in several areas, which results in considerable flow losses. In addition, additional components are required for the dust discharge pot.
  • the invention has for its object to provide a cyclone which on the one hand has a high degree of dust separation, on the other hand opposes the air a very low flow resistance.
  • the main advantage of the invention is that the supplied gases experience only a single 180 ° deflection, so that the flow resistance is kept very small.
  • the cyclone is designed in a simple manner essentially from plastic parts.
  • the plastic parts are assembled with suitable plug connections and can be exchanged without any problems.
  • the dust collector is fastened to the housing of the cyclone with a bayonet catch. It is easy to remove and can be emptied from time to time.
  • the lid of the cyclone is also attached to the dust collection container in a simple manner by means of a snap connection and can be easily removed.
  • the swirl of the gas flow is neutralized by the arrangement of guide vanes in the air outlet opening, that is to say the resistance of the cyclone is considerably reduced by orienting the flow.
  • the drawing shows: a cyclone in a half-sectional view.
  • the cyclone shown in the figure consists of a housing 1.
  • an inlet opening 2 is provided for the untreated air.
  • this inlet opening 2 are guide vanes arranged.
  • the cleaned air is deflected and flows according to arrow 7 in the direction of the air outlet opening 8.
  • the cleaned air leaves the cyclone via the air outlet opening 8 and can be fed to an oil bath air filter (not shown here) for further filtration.
  • the lid 4 is arranged with a snap connection on the dust collector 5 and can be easily removed.
  • the dust collector has grip strips 10. These handle strips serve to detach the dust collection container from the housing.
  • the connection between the housing and the dust collector is made via a bayonet lock 11.
  • An advantage of the cyclone is the flat design and the use of simple components that are made of thermoplastic by injection molding.
  • a particular advantage of the cyclone is that the guide wheel or guide vanes 9 contribute to pressure recovery. This means that a possible loss of pressure, which is caused by the rotational movement of the gases, is recovered by this conversion of the rotational movement into a linear movement. This considerably reduces the flow resistance caused by the cyclone.
  • the guide vanes 9 extend beyond the air outlet opening 8. In the figure, this extension of the guide vanes 9 is over the upper edge of the Air outlet opening 8 can be clearly seen. This measure also improves pressure recovery and can basically be used where three-phase flows are to be neutralized.
