Definitions

  • the invention described here relates to a loading and distribution device for the controlled filling of solids of two grain classes in shaft ovens, with a conveyor system that feeds into the shaft opening, at least in terms of material, working discontinuously and with a distribution screen arranged in the shaft under the shaft opening and open in the middle, whereby the Distance of the outer edge of the screen from the inner shaft wall is 1/10 to 1/5 of the inner diameter of the shaft.
  • FIG. 1 of DE-C 611 115 A device of this type is described in FIG. 1 of DE-C 611 115, in which the optional distribution of the filled solids to the center or to the edge of the shaft takes place solely with the aid of a distribution screen which is open in the center, by 180 ° a horizontal axis is rotated.
  • a bell arranged above the opening of the distribution screen distributes the solids during the filling in such a way that they always fall on the inward or outward sloping surface of the distribution screen.
  • DE-C-801 015 describes a different type of loading and distribution device in which the optional distribution inwards or outwards is not carried out by changing the inclination of a guide surface, but by optionally opening and closing the central region of a distribution cone.
  • the cone hood is swung away to the side if the centrally supplied filling flow is not to be distributed to the outside through the distribution cone, but is to reach the central area of the shaft. Since the swiveling away of the conical cover has to be done by actuation from the outside, a complicated, sealed rod guide is required as well as an additional movement of the rod into the pivoting movement implementing mechanics.
  • the task of the feeding and distributing device according to the invention described below is to avoid the complex known constructions and thus to achieve an optimal distribution of the solids of different grain classes with a minimal expenditure of constructive elements.
  • This object is achieved in that the distribution screen is arranged in a fixed manner and has a rotary flap which can be pivoted between a vertical and horizontal basic position above its central opening, the diameter of the rotary flap being matched to that of the screen opening.
  • the invention treads a fundamentally new path compared to the device according to DE-C 611 115, in that the directional distribution of the filling flow is no longer carried out by appropriate alignment of inclined surfaces.
  • a new path is also being taken compared to DE-C 801 015 in that no central inclined surface is used for the deflection to the outside.
  • the rotary valve according to the invention is therefore not only much easier to manufacture than the conical cover, but also its actuating device is simpler and more reliable.
  • the rotary valve essential to the invention optionally causes an inflow to the periphery, although no guide surface running there is used. Instead, a bulk cone is first formed on the transverse flap over which the incoming material is then directed outwards. After turning the rotary flap through 90 °, the filling quantity corresponding to the cone of bulk material also enters the shaft.
  • the swiveling traffic cone shown in DE-C-801 015 is in itself more complex than a flat circular disk. It has a much larger weight that can be swung away.
  • the pivoting movement due to a pure thrust movement of the actuating rod guided outwards requires additional kinematic means, which are not shown in this earlier patent. According to the construction shown there, the actuating rod would have to be flexible in order to be able to follow the pivoting movement.
  • the loading device according to DE-C-611 115 is constructed much more complex. Although it also uses an advantageous rotary bearing for optionally different distribution, it always rotates the outer distribution screen, which is fixed with us, by 180 °. Consequently, the bulk material must be redistributed to the periphery (Fig. 1) by means of guide means arranged above it in order to reach the guide surface of the outer distribution screen. In the version according to Fig. 2, an additional distribution cone must even be swiveled. Connecting means between the inner distribution cone and the outer distribution screen are also required, which have not been shown in Fig. 2.
  • the single figure shows a schematic representation of the basic arrangement of the loading device according to the invention: 1.2 is the (loaded) loading bucket with pull-out bucket bottom 1.3. 1.4 is the shaft opening (shown without lock). The distribution screen 1.6 with the rotary flap 1.5 open in this figure is located centrally below it.
