Definitions

  • the invention relates to a bulk silo with a centrally arranged, vented mixing or homogenizing chamber, the wall of which contains a plurality of constantly open through-openings for the material from the main silo room and which is connected to an inspection room which is formed by a hollow column within the chamber which can be accessed from below which contains observation openings to the chamber.
  • a mixing chamber arranged in a ring outside of a funnel-shaped part of the silo bottom contains an manhole with lockable hatches near the floor for maintenance work. Access to the chamber as a whole is only possible by walking through it.
  • a disadvantage of the known arrangement is that observation during operation is limited and maintenance is not possible at all; for the latter, the silo discharge must rather be shut down and the chamber emptied.
  • the object of the invention is to create a bulk material silo of the type mentioned at the outset which, with little effort, enables the chamber and the associated emptying devices to be better monitored and serviced.
  • the solution according to the invention consists in that the vent line and a silo outlet device are arranged in the centrically vertical hollow column.
  • the hollow column is arranged in the interior of the chamber, the construction effort required for it is considerably less than that for an inspection passage provided outside the chamber and equipped with an access channel. Since the hollow column is not only used for access, but also takes on additional functions in connection with the statics and the emptying function, its costs are also justified to a greater extent than that of a special manhole in an annular chamber.
  • the hollow column additionally stiffens the chamber ceiling, so that the chamber wall is relieved and can therefore be made weaker. It enables the ventilation line to be accommodated, the routing of which often poses problems.
  • the design of the inspection room as a central, vertical column brings with it the possibility that, on the one hand the functions of the chamber and the passage openings from the main silo room to the chamber and the silo outlet device provided for this purpose in the hollow column can be observed and influenced.
  • maintenance openings near the ground are expediently arranged such that they are approximately opposite the through openings. This enables maintenance of the passage openings, for example by poking.
  • the feature that the maintenance openings should lie approximately opposite the through openings is to be interpreted in this context so that the through openings are accessible from the maintenance openings by means of suitable tools such as picks, without the need to enter the chamber as such. This enables maintenance work to be carried out even if the chamber is not completely emptied or is even being throttled (especially on the side opposite the fault location).
  • the chamber should also be accessible from the hollow column, so that even more in-depth maintenance work can be carried out in the chamber room after the extraction operation has been shut down.
  • outlet devices distributed over the circumference of the hollow column are provided, so that in the event of a malfunction in one outlet device the other can continue to be operated during maintenance. It may also be expedient to provide discharge devices which can be operated directly from the floor of the main silo room, bypassing the chamber, so that the silo operation does not have to be completely at a standstill if maintenance work has to be carried out in the chamber which is not affected by the inspection during operation. or have maintenance openings done.
  • the hollow column can contain at least one inspection opening leading into the main silo space, this being expediently arranged laterally on a part of the hollow column leading into the main silo space beyond the chamber.
  • the silo body 2 seated on the ground via foundations 1 contains a main silo room 3, under the floor 4 of which a walk-in silo sub-room 5 is formed.
  • a mixing chamber 6 of known conical design is provided on the silo bottom 4, the wall of which contains a plurality of passage openings 7 above the floor 4, through which the material from the main silo room 3 when the ventilation devices 8 located at the passage openings are pressurized with compressed air, can flow into the chamber 9 in the fluidized state. If the compressed air supply to the ventilation devices 8 in the main silo room 3 is interrupted, the flow of material through the openings 7 is also interrupted, so that the chamber 9 can be emptied and entered.
  • the chamber also contains ventilation devices 10 which allow the material to flow in through two discharge openings 11, which are connected to conveying elements via suitable discharge lines 12, in the example shown to a pneumatic conveying line 13.
  • a ventilation line 15 is led down to a device suitable for receiving the exhaust air, for example part of the conveyor system.
  • the hollow column 16 according to the invention is provided centrally vertically, which is listed cylindrically from the bottom 17 of the chamber and reaches the wall 6 (in another embodiment, the ceiling) and even pushes with its part 18 into the main silo room 3, where it is closed by a blanket 19. It contains observation openings 20 in the height range that is normally above the crop level in the chamber space 9. Maintenance openings 21 are provided at approximately the same height as the passage openings 7. These can also be arranged somewhat higher than the passage openings. They should be such that the passage openings 7 and / or the chamber floor 17 can be reached from there, for example by means of picks, in order to remove solidifications, for example.
  • vent line 15 is laid within the hollow column and is therefore accessible. The same applies to the trigger devices emanating from the trigger openings 11.
  • the silo according to the invention is suitable, for example, for goods which are susceptible to faults, such as fly ash.
  • goods which are susceptible to faults such as fly ash.
  • its improved inspection and maintenance properties make it possible to dispense with elaborate mechanical conveyors within the silo, which are often otherwise necessary for such goods in order to make them conveyable.
  • the width of the inspection room in the hollow column should be so large that it is also possible to work with tools such as pick lances from there.
  • the diameter should be on the order of 2 to 3 m.
  • Discharge devices 23 extend from the bottom 4 of the main silo room 3, which are also guided to the conveyor 13 and allow the operation to be continued when the silo discharge through the chamber is temporarily stopped for maintenance of the chamber or a passage opening or a discharge element.
