Definitions

  • the present invention relates to improvements to the emptying devices of flat-bottom silos for grains or the like.
  • silos pose a problem at the end of their emptying. Indeed, as long as the volume of product is important, the emptying is carried out by gravity but towards the end of the emptying, the grains form on the bottom of the silo an oblique heap which does not evacuate any more because the mass which it represents , without being negligible since it can reach in the usual silos several hundred quintals, no longer crumbles.
  • the floor of the silo has openings obtained by making slits in the metal plate constituting said floor of the silo and then pushing the metal located on one side of the slit: thus "punctures" are made in the metal.
  • a second method consists in producing sheaths on the bottom of the silo alternating flat parts and hollow ribs having on each of their flanks "punctures" of air outlet, each of the ribs forming a ventilation channel. This process is not satisfactory either, because the grains rub on the parts of the floor between two ribs where an energy expenditure to overcome this friction. In addition, as the air jet at the outlet of the "punctures" extends obliquely to the direction of advancement of the grains, a certain energy is still consumed in pure waste.
  • the emptying is done by sending the air through two ventilation channels defining a drain groove.
  • the emptying is done by sending the air through two ventilation channels defining a drain groove.
  • French Patent No. 2,115,148 there is known a device for emptying silos having, at least, an air circulation corridor which opens out between sides inclined by slots formed by lamellae partially overlapping. These curved slats form slits opening upwards, in the form of a funnel.
  • the present invention relates to a device for emptying silos in which the grains rest on a floor arranged above the bottom of the silo and constituted by ribs, which each have a section in the form of an inverted Vee or the like, resting on said bottom by by means of two wings and by plates which join the ribs together so as to form buckets, each plate extending partially above the underlying plate disposed downstream, and said plates providing outlet openings for air coming from ventilation corridors located under said floor (see FR-A-2 115 148), characterized in that one of the two wings of each rib is full and the other has perforations whose total cross section is greater than that of the ventilation corridor and in that each ventilation corridor is delimited by the bottom of the silo, by a rib, by plates which join two adjacent ribs and in which are perforated és said orifices and by the solid wings of said adjacent ribs.
  • the device of the invention is applied to a silo 1, of rectangular section and with 2 plane bottom.
  • a metal floor formed by the alternation of plates 3 partially overlapping and of ribs 4 with a V-shaped section.
  • Each rib 4 has wings 5 and 6, forming vertical partitions, resting on the bottom 2.
  • the plates 3 form, with the oblique sides, adjacent ribs of the drainage buckets 7, each connected to a chute 8 extending outside the silo 1.
  • the wings 6 of the ribs 4 have orifices 9.
  • the wings 5 of two adjacent ribs 4 provide ventilation corridors 10 under the floor 3-4 of the silo.
  • the corridors 10 open out through orifices 12 in the wall of the silo into a channel 13 pressurized through said blower .
  • Each of the orifices 12 can be closed by a flap 14.
  • the troughs 8 open tightly into a discharge duct 15 extending out of the channel 3 and comprising a handling member such as a conveyor belt 16.
  • Each chute 8 is provided with a conventional sealing device not shown.
  • the total section of the orifices 9 of each of the wings 6 is greater than that of the corresponding ventilation passage 10.
  • Each plate 3 of slightly trapezoidal shape, has along its large base 3a a portion 17 bent downwards and along its small base 3b a portion 18 bent upwards.
  • oblong orifices 19 are provided, the width of which is less than the diameter of the ensiled grains.
  • the width of each oblong orifice is of the order of 1.5 millimeters.
  • each part 17 rests on the underlying plate (fig. 6).
  • each ventilation passage is about half that of the outlet duct of the fan which supplies it.
  • the assembly formed by the rib and its two wings can be constituted by a tunnel made of corrugated sheet metal with a circular or elliptical profile.
  • the total section of the oblong orifices provided on the rear part 18 of each plate can be greater than that of the orifices of the front part 17.
  • the corridors 10 and the buckets 7 pass through the wall of said silo and extend to that of said channel, said troughs connecting tightly to the evacuation pipe, fitted out as a recovery conveyor, by means of the usual chute.
  • the part of the buckets extending outside the silo is preferably covered. This provision applies particularly to silos with a circular base.
  • the ventilation corridors and the buckets extend to the wall of said transporter, but only said buckets open into the latter.
