Definitions

  • the invention relates to a silo according to the preamble of claim 1.
  • 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 is in a roughly radial direction from the outside inwards flows to the good discharge openings. Due to the radial flow direction of the goods from the circumference of the silo to the middle of the silo, areas close to the center flow out preferentially, while the goods do not drain off in the vicinity of the circumference even if the silo bottom is emptied.
  • a silo according to the preamble of claim 1 is also known (FR-A-24 13 291), in which the discharge openings are located in the annular bottom surface and the regions of the ring zone adjacent to the discharge openings are inclined towards the discharge openings, so that the material flows approximately tangentially to the material discharge openings. Since the discharge openings are open at the top, the silo content is loaded on the goods currently in the discharge opening.
  • silo in which the material flows approximately tangentially to the material discharge openings is known from FR-A-24 14 455.
  • the discharge openings are open at the top, so that the entire silo content presses on the material flowing through the discharge openings.
  • the invention has for its object to provide a silo of the type mentioned in the preamble of claim 1 so that a uniform outflow of the material through the material discharge openings is guaranteed.
  • 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.
  • a number of discharge chambers 4, 4 ′, 4 ′′ are arranged in the area of the base of the conical surface 2, which are approximately radially aligned and evenly distributed over the circumference of the silo.
  • Each of these discharge chambers is covered on the top by an upper cover 5, outer periphery delimited 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 (cf. FIG. 2).
  • Each discharge chamber 4, 4 ', 4 " is provided in the upper region with a vent connection 11 and in the lower region with a material discharge opening 12. Only indicated connection conveying channels 13 can connect to this material discharge opening 12, leading to a central outlet (with cellular wheel sluice or metering slide) ) lead: Instead, however, other connections of the material discharge openings 12 of the individual discharge chambers 4, 4 'etc. are 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 prevents the material from flowing off Fume extraction opening 12 favors.
  • zones 9 of the silo bottom which are arranged in front of the discharge openings 8 and are inclined in the circumferential direction are also 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 are formed in one piece if desired can be.
  • each discharge chamber (eg 4) is provided with two material discharge openings 8a, 8b arranged in the upper region of the two side walls 6, 7.
  • 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 bottom edge of the facing product 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.
