Definitions

  • the present invention relates to a device for distributing the loading material in a storage enclosure for the supply of a shaft furnace, said enclosure being provided with an upper opening for filling and with a lower opening for the flow, these two openings being associated with closing valves and / or sealing valves.
  • the device proposed is more particularly intended to equip an installation of the type proposed in document EP-A-0062770, that is to say a loading installation known as central supply, in which the storage hopper unloading the loading material on the chute is placed on the axis of the oven.
  • a loading installation known as central supply
  • the storage hopper unloading the loading material on the chute is placed on the axis of the oven.
  • the object of the present invention is to provide an effective device for reducing the segregation of particles in a storage enclosure of a loading installation of a shaft furnace.
  • the device according to the invention is characterized by a tube of section at least equal to that of the flow opening mounted coaxially in the enclosure and extending at least over the entire height corresponding to the diameter the higher of the enclosure and in that this tube is provided with an upper horizontal shoulder provided with a series of slots.
  • the projections defining the slots preferably have, on the three sides, a rising edge parallel to the wall of the tube.
  • FIG. 1 shows the top of an oven 10 in which there is a rotary or oscillating chute 12 for the distribution of the loading material in the oven.
  • a frame 14 which supports a storage enclosure 16 and a holding hopper 18, both arranged symmetrically around the axis 0 of the oven.
  • the storage enclosure 16 is designed in the form of an airlock and, for this purpose, is equipped with lower sealing valves 20 and upper valves 22 allowing the airlock 16 to be pressurized for loading as well. that its ventilation for its filling.
  • the bottom of the airlock 16 is extended by a flow tube 24 controlled by a metering member 26 consisting of two registers in the form of a spherical cap which open and which close symmetrically with respect to the axis 0.
  • the loading material is brought to the top of the installation by means of an endless belt which pours it into the holding hopper 18.
  • a chute is provided in order to already reduce the segregation at the level of this hopper 18.
  • rotary distribution 30 to distribute the material in this hopper.
  • an anti-segregation box 32 known per se has been mounted in the hopper on axis 0.
  • the upper part of the tube 34 has a horizontal shoulder 38 which is provided with slots 40 and projections 42.
  • the projections 42 are further provided on three sides with a rising edge 44.
