Definitions

  • the invention relates to a pneumatic mixing silo, at least comprising a storage space provided with floor ventilation and a feed inlet in the upper area and a mixing room arranged centrally in the lower area of the silo, also provided with floor ventilation, which is provided in its lower area.
  • Good passage openings are connected to the storage space and have at least one good outlet.
  • a mixing silo of the type mentioned above is known, for example, from the journal "Processing Technology", Issue 1/1973, p.8.
  • the mixing chamber is formed here by a relatively small chamber, which is closed at the top by a conical cover provided with a ventilation pipe and the outlet of which is located in the region of the bottom of the chamber.
  • the residence time of the goods in this mixing chamber is relatively short; the mixing effect is accordingly not entirely satisfactory in all cases. If the material fed to the mixing silo is very uneven and if the material is difficult to mix, it is generally necessary to premix the material to a large extent in the storage room.
  • the invention is therefore based on the object, while avoiding these defects, to design a mixing silo of the type mentioned in such a way that a substantial improvement in the mixing effect is achieved and also an excellent mixing effect is achieved in the case of strong inhomogeneity and / or difficult miscibility of the goods.
  • the mixing space in the area of the silo ceiling has an additional feed inlet that serves for the direct addition of correction material.
  • the wall separating the mixing space from the storage space extends as a preferably cylindrical, load-bearing wall over the entire height of the silo from the silo floor to the silo ceiling. If the silo ceiling is supported in the middle in this way, the thickness of the ceiling can be kept considerably lower.
  • the height of the mixing room overflow is also adjustable.
  • the residence time of the goods in the mixing room can be influenced within wide limits and thus the mixing effect can be optimally adapted to the respective application. In this way, larger fluctuations in the supply of goods to the storage room can also be easily accommodated.
  • the drawing shows this exemplary embodiment of the pneumatic mixing silo 1 in a largely schematic representation.
  • This mixing silo 1 can generally have a suitable polygonal cross-sectional shape or - as is preferred in the exemplary embodiment shown - an approximately circular cross-sectional shape.
  • the mixing silo 1 contains a storage space 2 with an annular cross section and a mixing space 3 arranged in the center thereof, which is connected in its lower area to the storage space 2 via through openings 4. Both the storage room 2 and the mixing room 3 are equipped on their floor with conventional devices 5 and 6 for floor ventilation.
  • the floor 7 of the mixing room 3 is preferably slightly lower than the floor 8 of the storage room 2.
  • the mixing silo 1 can be with a single feed 9 or with multiple feeds be provided, each good inlet 9 is arranged in the silo ceiling 10 and wherein - in the case of several good inlets - all the good inlets are evenly distributed over the silo ceiling 10 so that each good inlet 9 opens into the storage space 2.
  • the wall 11 separating the mixing space 3 from the storage space 2 is expediently designed in the form of a cylindrical, load-bearing wall which extends over the entire height of the silo 1 from the silo floor (7, 8) to the silo ceiling 10. This results in a mixing space 3 which is in the form of a cylindrical silo cell arranged centrally in the storage space 2; the cylindrical wall 11 can simultaneously support the silo ceiling 10 in its central region.
  • the silo ceiling 10 also contains, in its area covering the mixing room 3, a further material inlet 12, via which correction material (arrow 13) can be entered directly into the mixing room 3.
  • the material outlet 14 of the mixing silo 1 is designed as an overflow of the mixing space 3.
  • the height of this mixing space overflow referred to below as the main outlet, can be designed to be adjustable, ie in adaptation to the required operating conditions.
  • the main outlet 14 is at a height which corresponds to approximately -1- / 3 the total height of the mixing silo 1, this height however - as mentioned - can be lower or higher.
  • the mixing chamber 3 also has an additional material outlet 15 in the region of its base 7, which is used for the residual emptying and is referred to below as the remaining outlet.
  • a discharge conveyor is assigned to both the main outlet 14 and the remaining outlet 15.
  • These take-off conveyors can in principle be formed by any suitable horizontal conveyor, but it is advisable, particularly in the case of a pneumatic mixing silo, to provide pneumatic conveyor troughs 16 (for the main outlet 14) and 17 (for the remaining outlet 15) as the extraction conveyor.
  • pneumatic conveyor troughs 16, 17 can then be supplied in the same way as the floor ventilation devices 5, 6 from a common ventilation source.
  • the pneumatic conveying trough 16 of the main outlet 14 leads to a buffer container 18 which receives the goods before further conveying.
  • the material withdrawn from the mixing silo 1 can thus be withdrawn from a common point, namely the buffer container 18.
  • the increased arrangement of this buffer container 18 favors the arrangement of fittings and other devices for a further conveying device, not shown.
  • the mixing silo 1 can have a common ventilation (cf. arrows 20) for the storage room 2 and the mixing room 3.
  • a common ventilation filter can be provided on the silo ceiling 10.
