Definitions

  • the invention relates to a silo according to the preamble of claim 1.
  • Silos of the type required in the preamble of claim 1 are known for example from DE-OS 23 52 455 and 27 24 928.
  • the material discharge openings are arranged in the lower region of the central cone surface, the ring zone of the base surrounding the cone surface being sloping inwards in such a way that the material flows towards the material discharge openings in a roughly radial direction - moving from the outside inwards.
  • the invention is therefore based on the object of designing a silo of the type mentioned in the preamble of claim 1 in such a way that a uniform outflow of the material from all cross-sectional zones (not only from the central zones) is ensured. Furthermore, the new silo should be characterized by perfect residual emptying and a good mixing effect. Finally, there should also be the possibility, if desired, of dispensing with metering and shut-off devices and still ensuring a uniform discharge of material.
  • the material in the silo according to the invention does not flow in the radial direction, but rather approximately tangentially to the material discharge openings, the previously available favoring of zones close to the center is avoided and even flow of the material present in the area close to the periphery is ensured. In this way, a perfect residual emptying of the silo as well as - when using the silo for mixing or homogenizing purposes - a good mixing of the material, including the areas close to the circumference, can be achieved.
  • the silo for flour-like bulk material illustrated in FIGS. 1 to 3, only the lower area essential for understanding the invention is illustrated.
  • the silo has a round cross section with a cylindrical outer wall 1 and a silo bottom, the central region of which is formed by an approximate conical surface 2.
  • the tip 3 of this conical surface points upwards.
  • Each of these discharge chambers is at the top by a upper cover 5, limited on the outer circumference by the outer wall 1 of the silo and laterally by two side walls 6, 7.
  • a material discharge opening 8 is provided, through which the material is discharged from the interior of the silo into the chamber 4.
  • the material discharge opening 8 extends in the radial direction from the central conical surface 2 to the cylindrical outer wall 1 of the silo (see FIG. 2).
  • zones 9 of the silo base are inclined in the flow direction of the material, via which the material flows in the direction of the arrows 10 to the material discharge openings 8.
  • the zones 9 of the silo bottom which are inclined in the direction of flow of the goods each extend from the top cover 5 of a discharge chamber (for example 4) to the lower edge of the discharge opening 8 of the discharge chamber adjacent in the circumferential direction (for example 4 ', see Fig. 3).
  • Each discharge chamber 4, 4 ', 4 "is provided in the upper region with a vent port 11 and in the lower region with a Gutabzugsö réelle 12 to this Gutabzugsö réelle 12 may, for example, only indicated compound chutes 13 Toggle: close, with a central outlet ( Cell rotary valve or metering slide) instead however, other connections of the product discharge openings 12 of the individual discharge chambers 4, 4 ', etc. are also possible.
  • a closable opening 16 is provided in the inner boundary wall of the discharge chambers 4, 4 ′, 4 ′′, through which the discharge chamber in question can be accessed from the interior 15.
  • the outer wall of the discharge chamber 4, 4 ', 4 " is formed by an inclined surface 17, which promotes the flow of the material to the material removal opening 12.
  • zones 9 of the silo bottom which are inclined in the circumferential direction in front of the material discharge openings 8 are ventilated as are the covers 5 provided on the top of the discharge chambers 4, 4 ', 4 ". It is understood that the zones 9 and the covers 5, if desired, in one piece can be trained.
  • each discharge chamber (for example 4) has two material discharges arranged in the upper region of the two side walls 6, 7 openings 8a, 8b provided. Zones 9a, 9b inclined in the direction of flow of the goods each extend from a circumferential point between two adjacent discharge chambers (e.g. 4, 4 ') to the lower edge of the facing discharge openings (e.g. 8b, 8'a) of these two discharge chambers 4 , 4 '.
  • the slides assigned to the discharge openings 8a, 8b can either be operated together or individually.
  • the material in the silo according to the invention flows in the tangential direction into the individual discharge chambers 4, 4 ', 4 ", either only from one side (FIG. 3) or from both sides (FIG. 4
  • the material discharge opening 12 in the lower region of the discharge chambers 4, 4 ', 4 " is covered by the upper cover 5 to relieve pressure.
  • the interior of the individual discharge chambers is vented via the vent connection 11. This prevents undesirably large amounts of loosening air with the material from reaching the downstream devices through the product discharge opening 12.
  • the tangential inlets to the individual discharge chambers can be easily closed from the interior 15 by the slide 14, for example in order to be able to carry out maintenance work in the outlet area.
  • the slides 14 are also closed for mixing or homogenization.
  • the goods are then ventilated zone by zone. Mixing takes place both in the circumferential direction and in the radial direction. It is not absolutely necessary to mix the material when it runs out of the silo.
  • the flour can be taken from the ventilated zone of the silo.
  • the silo can be emptied practically completely. If lumps form or the material solidifies in the outlet area, it is possible to poke through openings from the interior 15.
  • zone 9 of the silo bottom which is located in front of the discharge openings 8 and is inclined in the direction of flow, is followed in each case by a zone 19 of the discharge chamber 4, 4 ′, 4 ′′, which is likewise inclined in the direction of flow
  • the discharge chamber is given a kinked shape in this way, the material initially passing through the discharge openings 8 without any deflection, since in the selected embodiment the zone 19 has the same inclination as the zone 9.
  • the inclined zone 19 located in the discharge chamber is also suitably ventilated.
  • the material discharge openings 8a, 8b are provided in the lower region of the two side walls 6, 7 of approximately radially oriented discharge chambers 4, which are designed as mixing chambers provided with floor ventilation, the Side walls 6, 7 are arranged like a roof. A plurality of material discharge openings 8a, 8b arranged next to one another in the radial direction are provided in each side wall 6 or 7.
  • the discharge chambers 4 have a bottom 20a, 20b which is inclined towards the center line 21 (which runs in the radial direction) and which at the same time has a gradient in the radial direction and adjoins the zones 9a lying outside the discharge chambers 4 and inclined in the circumferential direction. 9b of the silo floor with approximately the same inclination and without a step.
  • a conveyor trough 22 runs along the center line 21 of the bottom of the discharge chamber 4.
  • the material likewise enters the discharge chamber 4 approximately tangentially, but in mutually opposite circumferential directions, through the material discharge openings 8a, 8b of the two side walls 6, 7 and experiences here through the collision of the material flows coming from opposite circumferential directions and through the deflection an intensive mixing and homogenization tangentially in the radial direction.
