Definitions

  • the invention relates to a silo for bulk material according to the preamble of claim 1.
  • a bulk goods silo according to the preamble of claim 1 is known for example from AT-C-303 625.
  • the venting device connected to the central extraction chamber is formed here by a pipeline which runs from the tip of the conical extraction chamber centrally through the interior of the silo to the silo ceiling.
  • a disadvantage of such a design is the considerable mechanical stress to which this ventilation line is exposed through the material in the silo.
  • the prior art also includes silos (DE-B-25 39 753 and DE-A-27 27 499), in which the material is discharged from the central discharge chamber via a discharge chamber leading radially from the discharge chamber to the peripheral wall of the silo which is also the ventilation of the trigger chamber.
  • a vent line leads from this emptying chamber on the peripheral wall of the silo to a dedusting device or to the upper part of the silo interior.
  • the invention is therefore based on the object, avoiding these disadvantages of the known designs, a silo according to the preamble of claim 1 so that despite simple construction and avoidance of undesirable mechanical stresses of the ventilation device, a uniform flow over the entire circumference of the material from the silo interior to the central deduction chamber is guaranteed.
  • the ventilation device contains a ventilation tunnel which is known per se and leads from the discharge chamber to the peripheral wall of the silo and is connected to a ventilation line.
  • the side walls of this ventilation tunnel have openings through which the material from the silo interior, the ventilation tunnel and through this the central extraction chamber inflows.
  • the venting tunnel thus also allows goods to be transported to the central discharge chamber and in this way ensures uniform, rotationally symmetrical loading of the central discharge chamber.
  • the bulk goods silo illustrated in the drawing contains a silo room 1 for receiving the bulk goods and a room 2 for receiving further conveying devices.
  • the bottom 3 of the silo room 1 is arranged in a known manner inclined towards the center and provided with pneumatic ventilation devices 4.
  • a discharge chamber 5 is arranged centrally above the floor 3 and is enclosed by a conical hood 6. At the lower edge of the hood 6, openings 7 are provided through which material enters the central discharge chamber 5 from the silo space 1.
  • the trigger chamber 5 extends through the Floor 3 through and is provided in its lower area with Gutausöffötechnisch 8.
  • a ventilation device is connected to the extraction chamber 5, which contains a ventilation tunnel 10 arranged on the silo bottom 3 and leading from the extraction chamber 5 to the peripheral wall 9 of the silo, to which a ventilation line 11 is connected, which leads to the upper part of the silo space 1.
  • the ventilation tunnel 10 provided with a rider-like cover 12 has openings 13 in its side walls, through which material enters the ventilation tunnel 10 from the silo space 1 and flows into the extraction chamber 5 through this ventilation tunnel.
  • the ventilation tunnel 10 is connected to the extraction chamber 5 on the one hand via a ventilation opening 14 located in the upper region of the extraction chamber and on the other hand is connected to the extraction chamber 5 via a material outlet opening 15 which lies directly above the floor 3 of the silo.
  • the bottom of the ventilation tunnel 10 is provided with pneumatic ventilation devices 16, which serve to feed the material to the extraction chamber 5 through the openings 13 from the silo space 1 into the ventilation tunnel 10.
  • pneumatic ventilation devices 16 serve to feed the material to the extraction chamber 5 through the openings 13 from the silo space 1 into the ventilation tunnel 10.
  • the floor 3 of the silo space is also provided directly in front of the openings 13 of the ventilation tunnel 10 with pneumatic ventilation devices 17a, 17b.
  • lateral ventilation devices 16a, 16b are also provided in the bottom of the ventilation tunnel 10 and are arranged in the region of the openings 13.
  • the operation of the silo is advantageously carried out as follows according to the method according to the invention: There are two separate blowers, of which the first blower is used to ventilate the central discharge chamber 5 and the second blower is used to ventilate the silo bottom 3 and the venting tunnel 10.
  • the first blower continuously ventilates the central discharge chamber 5 and the second blower alternately either the silo floor 3 or the ventilation tunnel 10. In detail, this is done as follows: The level in the central discharge chamber 5 has dropped to a minimum value, so that the ventilation pressure of the central discharge chamber 5 is set If the minimum value is reached, the ventilation of the ventilation devices 16 of the ventilation tunnel 10 is switched off and the ventilation of the silo bottom 3 is switched on. For this purpose, for example, two channels lying opposite one another can be ventilated with their ventilation devices 4. During the subsequent filling of the central extraction chamber 5, the air from the ventilation of the central extraction chamber and the air from the silo ventilation as well as the air displaced from the central extraction chamber by the rising fill level are discharged via the ventilation tunnel 10.
  • the aeration of the silo floor is switched off and the aeration devices 16 of the Vent tunnel 10 turned on.
  • the material that has entered the venting tunnel 10 during the filling of the central extraction chamber 5 is reliably guided or returned to the central extraction chamber.
  • the lateral ventilation devices 16a, 16b arranged in the venting tunnel 10 in the area of the product inlet openings 13 are combined with the pneumatic ventilation devices 17a, 17b located outside the ventilation tunnel 10 in front of the product inlet openings 13. These ventilation devices 16a, 16b, 17a, 17b are operated simultaneously with the ventilation devices of the opposite sector of the silo floor 3.
