Definitions

  • the invention relates to a metering and mixing arrangement for flowable solids according to the preamble of the main claim.
  • the invention has for its object a To create metering and mixing arrangement in which a very intimate mixing of the different fractions takes place without the need to use a cyclone mixer.
  • metering wheels having metering chambers allow certain quantities to be removed from the associated silo without the silo being sucked empty due to the negative pressure prevailing in the discharge line.
  • the quantity finally discharged from the metering device into the associated discharge pipe is determined by a control valve.
  • the mixing of these certain, simultaneously available flow rates then takes place in a mixture delivery pipe due to the pneumatic conditions prevailing there.
  • the products are therefore introduced into one another in their final mixing ratio and then mixed by the movement occurring due to the pneumatics.
  • silos 1, 2 and 3 are shown, which are equipped at their lower end with metering housings in which metering wheels 4, 5 and 6 are arranged so as to be driven in a rotating manner.
  • To the dosing housing open suction pipes 8, 9 and 10, which are merged in the drawing at 19 and open into a mixture delivery pipe 11.
  • a driving nozzle arrangement 12 is switched on, by means of which a negative pressure is generated in the individual suction pipes 8, 9 and 10 and a delivery pressure is generated in the mixture delivery pipe 11, so that the suction pipes 8, 9 and 10 each face the mouth of these suction pipes in the distributor housing revolving dosing chambers 7 are sucked empty and the material is discharged.
  • a control valve 14, 15 and 16 is switched on, through which the flowing through the suction lines 8, 9, 10, ie. H. extracted amounts can be adjusted.

Claims (6)

  1. Dispositif de dosage et de mélange pour solides coulants, comprenant des silos (1, 2, 3) qui contiennent et stockent les solides, ainsi que des dispositifs d'extraction disposés sur le côté de sortie des silos (1 à 3) et qui sont constitués par des roues de dosage (4, 5, 6) pouvant être entraînées en rotation, prévues à l'intérieur de boîtiers de dosage, les roues de dosage (4, 5, 6) formant des chambres de dosage (7) avec les boîtiers de dosage, et des conduites d'évacuation, qui se raccordent aux dispositifs extracteurs et sont attaquées pneumatiquement, caractérisé en ce que les conduites d'évacuation sont constituées par des tubes d'aspiration (8, 9, 10) qui se rejoignent dans la région d'une zone de jonction (19), cependant qu'un dispositif (12) à buse d'entraînement est intercalé entre la jonction (19) et un tube de mélange et de transport (11), et qu'une vanne de réglage (14, 15, 16) est associée à chaque tube d'aspiration (8, 9, 10).
