Definitions

  • the invention relates to a large-capacity silo for dusty and fine-grained bulk material with a conical hood, which stands in the middle of an annular silo bottom, which is provided with pneumatic loosening devices and is inclined to outlet openings in the cone.
  • Such silos are used, for example, for the storage of cement, fly ash or coal dust.
  • Such substances are withdrawn from such a silo by fluidizing the bulk material in the region of the annular silo bottom and draining the fluidized bulk material through metering elements.
  • boxes can be arranged in the area of the silo bottom, the upper side of which is covered with a porous material, so that the bulk material lying on them is fluidized by blowing air into the boxes.
  • This discharge is supported if the annular silo bottom between the cone and the silo outer wall is inclined in the direction of the respective outlet openings.
  • the removal of the air for fluidizing is a major problem, since in large silos with a diameter of, for example, 25 meters and a filling height of several meters, the air for fluidizing cannot be forced through the column of the bulk material, but with through Discharge openings must escape.
  • DE-A 2,352,455 shows a large-capacity silo with ventilation mats, in which the blown-in air must escape through the metering device. This makes the silo unsuitable for long-term storage, because a relatively large area must be ventilated with correspondingly large amounts of air.
  • DE-OS 36 09 244 describes a device in which only a central ventilation line bypasses the metering element, so that the loosening air flows into the homogenizing chamber from all parts of the soil.
  • a central ventilation line bypasses the metering element, so that the loosening air flows into the homogenizing chamber from all parts of the soil.
  • box-shaped outlet chambers are connected to preferably wide outlet openings in the cone, each of which carries a ventilation chamber, which can be designed as a tube which is connected at the end of an outlet chamber in front of a shut-off and metering element.
  • the ventilation chamber is effective as a dedusting device, since the filling pressure of the silo is reduced as the stored goods flow through the outlet chamber, so that there is only a low filling pressure in the area of the lower ventilation chamber.
  • the loosening air can thus be easily diverted and dosing takes place without the need to also discharge the loosening air through the metering opening, because it is possible to connect a ventilation pipe to the respective ventilation chamber, which is only behind the shut-off valve and metering element in the discharge line of the bulk material flows.
  • the bulk silo 1 shown in the drawing for dusty bulk material has a cylindrical silo wall 2 to which a conical hood 3 is arranged concentrically, which is connected to the wall 2 by an annular base 4.
  • the ring base 4 is provided with saddle-shaped inclined walls 5 and with grooves 6 arranged between the saddles and inclined towards the center of the cone, which, like the saddle walls 5, are provided with ventilation elements 8.
  • the cone hood is provided with wide or slit-shaped outlet openings 7, the number of which corresponds to that of the channels 6, so that the filling material from the saddles 5 and the channels 6 is to be conveyed out of the ventilation elements 8 through the outlet openings 7 into the cone under the influence of fluidizing air .
  • box-shaped outlet chambers 9 are connected, each carrying a tubular ventilation chamber 10.
  • a shut-off and dosing element 11 is connected to the outlet chambers 9, through which the filling material is to be discharged into a discharge line 13 and from there into a centrally arranged collecting container.
  • the air required for loosening or fluidizing is thus conveyed together with the bulk material through the outlet openings 7 into the outlet chambers 9, but passes out of these in front of the metering elements 11 into the ventilation chambers 10, in which part of the bulk material also accumulates , while part of the conveying air is discharged into the discharge line 13 via a connected ventilation pipe 12 behind a metering element 11.
  • the filling pressure of the silo 1 is thus reduced when the stored goods flow through the outlet chambers 9, so that there is only a relatively low filling pressure in the area of the lower ventilation chambers and the stored goods can expand in the ventilation chamber.
  • venting chambers 10 can be provided with air connections 15 in order to loosen up their contents if, for example, the system has not been in operation for a long time.
