Definitions

  • the invention relates to a method and a device for cleaning the sieve trays, in particular in vibration classifying machines of the multi-deck design, in which the sieve fabrics are held between two tensioning rails and can be tensioned on the sieve trays in the flow direction of the material by adjusting devices acting on the tensioning rails on at least one side.
  • the present invention is intended to avoid the disadvantages of the known device and to solve the problem of adequate cleaning of the sieve fabric even when difficult Contamination to be removed from the sieve cloths in machines that continue to run, ie without achieving a significant loss of production.
  • the method can act on the tensioning rails for the screenings tensioning devices, which can be designed as a pneumatic cylinder connected to a compressed air connection of a known type.
  • the tensioning rails for the screen fabric can, however, also be suspended from the machine frame by means of tension springs, wherein the relaxation of the screen fabric can then take place by means of electromagnets or tension cylinders actuated on a case-by-case basis.
  • the tensioning devices should expediently be connected to the tensioning rails for the screen fabric by guides, gel connections or the like.
  • baffles for the product formed as mudguards above the tensioning rails and the tensioning devices.
  • support or blow bars should be arranged below the sieve fabrics transversely to the flow direction of the material.
  • 10 denotes the sieve fabrics, which are clamped at one end in fixed tensioning rails 11.
  • the other end of the screen fabric 10 is connected to movable tensioning rails 12.
  • the tensioning rails 12 are connected by means of guides 21 to tensioning devices 14 which are fastened to the machine frame and pressure medium cylinders for e.g. If air or oil is presentHenn pressure medium is present on the piston of a pressure cylinder, the screen fabric is stretched, i.e. the piston moves to the right in the direction of the arrow. When the pressure medium is switched off, the piston moves to the left in the direction of the arrow and the screen fabric 10 is relaxed.
  • the pressure medium is supplied to the cylinder 14 through a line 18. 1 shows the arrangement of three sieve trays 10 with tensioning devices 14 on a vibration classifying machine 20 provided with vibrating devices 19.
  • the fabric is tensioned in that the tensioning rail 12 is fastened to the machine frame by means of tension springs 15.
  • the relaxation of the screen fabric 10 takes place in that the tensioning rail 12 is pulled to the left by the electromagnet 16 in the direction of the arrow. If the electromagnets are switched off, the springs 15 pull the screen mesh tight again and tension it with it.
