Definitions

  • the invention relates to a silo container for bulk material with a tendency to incrustation, with a main container part, an outlet funnel arranged underneath and connected to the main container part, a grating extending across the container cross-section at the lower end of the main container part and in the outlet funnel and with separate vibrating devices for loosening of the goods in the main part of the container and in the discharge hopper.
  • an upwardly curved perforated base is provided between the main container part and the outlet funnel, on which a grid-like vibrating element is supported elastically.
  • Another grid-like vibrating element is provided near the lower opening of the discharge funnel.
  • at least the upper vibrating element is exposed to the pressure of the whole pillar and is therefore considerably stressed. Furthermore, it is only possible with a large expenditure of energy and with considerable wear and tear to remove bulk material with a tendency to incrustation from the silo container with these heavily loaded vibrating elements.
  • a known silo container (DE-AS 1 114 147), in which only the discharge hopper, but not also the main container part, is provided with one or more vibration drives, also shows an insufficient function with regard to the discharge of material that tends to incrust.
  • silo container DE-AS 1 266 231
  • the outlet funnel is divided into an upper and a lower funnel part, of which the upper funnel part is fixedly connected to the main container part and the lower funnel part is elastically connected to the upper funnel part , wherein one vibrating device is assigned to the upper and lower funnel part.
  • a silo container is also known (DE-Gm 6 926 956), in which the main container part widens from top to bottom and a hood covering the central outlet opening is provided in the outlet funnel, which forms an annular gap together with the wall of the outlet funnel.
  • the main part of the container and the discharge funnel are set in vibration by a common vibratory drive.
  • the invention is therefore based on the object of creating a silo container of the type mentioned which, with a simple structural design, ensures reliable and uniform discharge of the bulk material from the container - even with material that tends to incrust.
  • a crusted column of material is passed through the Vibration movement of the main container part detached from the container wall to be expanded downwards.
  • This pillar supports itself with its own weight on the grid at the lower end of the main container part and is rubbed off by the grid under the effect of the vibration and thereby made free-flowing and portable again.
  • the air gap due to the cross-sectional expansion of the main container part between the detached crusted material column and the silo wall which has its greatest value directly above the grille at the lower end of the main container part, prevents the material from baking on the container wall again at this particularly critical point.
  • the subdivision of the discharge funnel into two parts that can oscillate independently ensures, with simple constructional means, that the bulk material is loosened further as it falls through the discharge funnel. Since the vibrating devices are attached to the outer walls of the container parts, they are not affected by the bulk material. On the other hand, the grids attached to the inside of the container exert an intensive comminution effect on incrusted bulk material during the shaking movement.
  • the grid provided in the lower funnel part has a small mesh size than the grid arranged in the main container part.
  • a control device can also be provided, by means of which the shaking device of the lower funnel part is constantly switched on and the shaking device of the unit consisting of the main container part and the upper funnel part is only switched on temporarily. If the shaking device of the unit consisting of the main container part and the upper funnel part is only put into operation in this way when there is a strong accumulation of material, the energy requirement of the silo container can be significantly reduced.
  • the illustrated silo container has an upper main container part 1 and a two-part outlet funnel, which contains an upper funnel part 2 and a lower funnel part 3, which are elastically connected to one another by a sealing sleeve 4.
  • the lower edge 1 of the main container part 1 is firmly connected to the upper edge 2a of the upper funnel part 2, so that the upper container part 1 and the upper funnel part 2 form a solid unit with one another; this unit consisting of the upper container part 1 and the upper funnel part 2 is elastically supported on the foundation 6 by means of conventional vibration supports 5.
  • a grid 8 formed essentially from upright fastened, rust-like rods 7 is firmly installed, and on the outer wall of the upper funnel part 2 a vibration drive 9 of conventional design is attached, which leads to a vibrating device heard and through which the unit consisting of the main container part 1 and the upper funnel part 2 (including glitter 8) can be vibrated overall.
  • the main container part 1 has a cross-section that increases from top to bottom. It can expand evenly from top to bottom in the form of a truncated cone or a truncated pyramid.
  • a sliding coating or a sliding layer 10 can be provided on the inner wall of the main container part 1 in order to further promote the sliding down of the bulk material.
  • the lower funnel part 3 is also provided in its upper region with a grating 11 extending over the entire cross section, which is attached to the wall of this funnel part 3 in such a way that the lower end of the upper funnel part 2, which protrudes somewhat into the lower funnel part 3 , does not come into contact with this second grid 11.
  • the second grille 11, like the first grille 8, is essentially constructed from bars 12 that are fastened upright and assembled in a rust-like manner.
  • the mesh size of this second grid 11 can be the same size as that of the first grid 8; However, the mesh size of the second grid 11 is expediently kept somewhat smaller than that of the first grid 8.
  • the mesh size of the second grid 11 depends primarily on the size of the outlet opening 13 (at the lower end of the funnel part 3) and on the shut-off or metering element 14 arranged underneath, since the second grid 11 should, if necessary, shred the bulk material to such an extent that no blockages of the outlet opening 13 and the organs downstream of it can occur.
  • the lower funnel part 3 has its own vibration drive 15 on its outer wall and can consequently be shaken by this vibration drive independently of the unit consisting of the main container part 1 and the upper funnel part 2.
  • the two vibration drives 9 and 15 are connected to a control device 16.
  • This control device 16 can, for example, make the vibratory drive 15 of the lower funnel part 3 work continuously and only temporarily switch on the vibratory drive 9 of the main container part 1 and the upper funnel part 2.
  • the vibration drive 9 is expediently switched on as a function of the degree of hardening or incrustation of the bulk material column above the grid 8.
  • the vibration drives 9 and 15 can be operated either with the same or with a different frequency and amplitude.
