Definitions

  • two types of containers are known from the patent literature and technical use according to the preamble: On the one hand, those that are preferably known from the management of waste glass (for example, according to WO-A-93/12018), and on the other hand, those that are mostly known as Railway wagon bodies are designed and have a flap-operated emptying opening.
  • Waste glass containers generally have individual drop-in openings, preferably for bottles, stand at a recycling point for some time, are removed by special trucks and replaced by empty containers.
  • the emptying takes place either in the glassworks or on a train station by lifting the container shell or lowering the pyramid or conical bottom.
  • the formation of such containers is in accordance with the loading and unloading speeds, and the amount of the bulk goods.
  • both loading and unloading are characterized by a high temporal mass flow.
  • Special devices so-called railway gutters, are also required for unloading.
  • Special storage devices and silos are required for the storage prior to loading and subsequent storage after unloading.
  • the use of such bulk goods containers designed as wagon bodies therefore requires high capital expenditure, for the containers themselves, for silos and for the railway gutters.
  • the unit of use is also always at least one whole wagon, even if it is only to be partially filled.
  • GB-A-1'071'600 describes a container that has a floor drain. It contains in its lower part a multiplicity of roof-shaped webs and a further component, which also has a multiplicity of roof-shaped webs, which are arranged such that they pass between the roof-shaped webs of the container, in such a way that when the container is in relation to the Part is in a certain position, the webs of the component and the webs of the container come to lie next to each other and the container is closed with it.
  • the disadvantage of this device is that the container can only be emptied at specially provided unloading stations and the component contains moving parts that are susceptible to malfunction.
  • Fig. 1 the container according to the invention is shown in a perspective view. It consists of a frame 1, for example welded together from square tubes, with four vertical struts 4, which are connected at their upper ends by horizontal struts 20. In the lower part of the frame 1 strong side plates 2 are welded on all four sides. A container 3 is embedded in this frame 1 in such a way that it can move along the vertical struts 4. For this purpose, 3 guides 5 are attached in the corners of the container, which are based on 6 and 7 are described in more detail. In the interior of the container 3, roof-shaped connecting struts 6 are visible which connect and stiffen the longitudinal walls of the container 3.
  • the upper edge of the container 3 is connected to a roof-shaped bar 7 for stiffening, for example by welding, which at the same time serves as a deflecting device, so that no bulk material remains on the edge.
  • a roof-shaped bar 7 for stiffening, for example by welding, which at the same time serves as a deflecting device, so that no bulk material remains on the edge.
  • Around the container 3 also runs - welded to it - another, downwardly and outwardly inclined strip 8, which, in the position of the container according to FIG. 1, the upper edge of the side plates 2 - and thus also the space between side plates 2 and container 3 - covers.
  • flat side plates 2 - as shown - in the sense of the invention, flat hollow profiles or rib plates can also be used, the ribs of which run in the horizontal direction.
  • Fig. 2 shows the container of Fig. 1 in longitudinal section. This shows that the container 3 is drawn in the shape of a truncated pyramid in its lower part.
  • the bottom opening of the container 3 is closed by a plurality of roof-shaped webs 9, 10.
  • the webs 9 hatched vertically in FIG. 2 are welded to the longitudinal side plates 2 of the frame 1, the webs 10 hatched horizontally in FIG. 2 to the container 3.
  • Short pieces of webs welded to the container 3 are identified by the number 11. They stiffen the bottom of the container 3; their dimensioning and position is shown in more detail in FIGS. 4 and 5.
  • the two outermost roof-shaped webs 10 are welded to a pair of vertically extending plates 12, one of which is shown in plan view in FIG. 2. Their task is explained in more detail in connection with FIG. 3. in the position of the container shown in Figure 2, the container 3 is closed; it can be loaded with the bulk material to be transported.
  • four - only schematically drawn - load introduction devices 13 are present in the four upper corners of the frame 1.
  • Another possibility is to drive under the side plates 2 of the frame with the forks of a forklift.
  • Fig. 3 the container is drawn in the open or emptying position.
  • the filled container is, for example, two transverse Beams turned off, which only support the vertical plates 12.
  • the frame 1 lowers on it, guided by the guides 5, and thus releases the openings closed by the webs 9.
  • this relative movement can also be generated in such a way that the frame 1 is placed on a foundation and the beams - or a lifting device replacing them - are raised.
  • the unloading process can take place in a proportionate manner.
  • Fig. 6 shows an embodiment of the guide 5.
  • a steel bracket 15 is welded, which rests on two sides of the vertical strut 4, but only has legs so long that they can slide past the side plates with enough play.
  • the angle 15 is stiffened by means of a support plate 18 which extends, for example, over the entire length of the angle 15.
  • Each corner of the container 3 is provided with a guide 5 in the manner described.
  • a first variant contains 15 plastic sliding plates inserted between vertical strut 4 and angle 15.
  • a second variant can be seen in FIG. 7.
  • the container according to the invention shown in FIGS. 1 to 7, can in principle be produced in any desired size. Modifications only relate to static elements that are not essential to the invention. Of course, it is intended to be designed as an ISO standard container for rail and ship transport.
  • the load introduction devices 13, which are only shown schematically, are then to be designed as devices corresponding to the ISO standards; the corresponding devices at the lower four corners must also be provided accordingly.
  • the container is simple and robust and inexpensive to manufacture. Instead of storing different grain sizes of bulk goods in expensive and often underutilized silos, these can be stored in the containers according to the invention, which often also saves unnecessary reloading processes. Furthermore, capital-consuming railway gutters can be saved: the containers are unloaded from universally usable container railway wagons and lifted and emptied onto a relatively easy-to-design emptying device. If the containers are not to be emptied at first, they can be stacked, for example as an ISO standard container. The transport train is immediately free again and silo capacity is not required.
