Definitions

  • the invention relates to a transfer chute as a material transfer point for bulk materials.
  • Such devices are used to transfer the material to be conveyed from one conveyor to another and are characterized by a closed as possible construction, which is intended to prevent deterioration of the environment by the subsidized Good or associated with the promotion of dust.
  • Devices and systems for conveying bulk materials must be designed in terms of mechanical engineering as well as bulk material technology.
  • the promotion of bulk materials has an at least partially uncontrollable movement of the conveyed result.
  • a decisive factor in this context is the relative movement of the particles.
  • An increase of the relative movements and thus of the granular state of aggregation manifests itself in an increase in the granular temperature and a change in the bulk material properties.
  • a solid-like, very slowly flowing bulk material changes to a liquid-like state as the shear gradient increases. With further increasing fluctuations of the individual Particle movements are more closely resembling the phenomenological properties of the bulk material than those of a gas.
  • the invention is therefore based on the object to avoid the formation of dust in the area of a transfer chute to the largest possible extent to perform the downstream aggregates and systems for dedusting as low-power as possible.
  • the invention provides in its basic idea that the inlet chute is divided into at least two chambers by at least one in the flow direction of the bulk material in the inlet chute partition wall and the discharge conveyor is connected to the chambers, wherein the feed conveyor in him in the conveying direction nearest task chamber of the inlet chute gives up and the partition with its base adjusts the layer height of the discharged from the discharge conveyor from the feed bulk material determining distance such that the withdrawal amount of the bulk material from the feed chamber is lower than the discontinued by the feed conveyor in the feed chamber bulk.
  • the invention is thus based on the principle that run-in chute through which the conveyed material passes into the transfer chute to execute such that the Filling no longer - as prevailing in the art - vertically, but gradually horizontally.
  • the uncontrolled movement of the particles is reduced to a minimum and at the same time the flow of material in the intake chute is calmed down, without influencing the overall material handling process.
  • Linked to this filling strategy is a reduction of the drop height to a minimum. With this reduction, a minimization of the wind vision effect, the abrasion and the particle breaks can be achieved.
  • the transfer chute according to the invention has one or more partitions which divide the inlet chute in at least two or in any number of chambers.
  • All other chambers provided can divide the remaining intake chute volume in any manner, for example, by constant chamber volume or by a steadily decreasing chamber volume.
  • the exhaust side (lower) base of the partition protrudes less far into the maximum possible - flow in as the base of the opposite 'the Conveying direction previous partition.
  • a new layer of the conveyed material stream formed in addition to the bulk material layers already formed by the base points of the bulk material layers opposite to the conveying direction is permitted by each lower base of a partition wall.
  • a plurality of partitions for dividing the inlet chute are arranged in a feed chamber and in several downstream overflow chambers in the inlet chute, the bases of the downstream partitions are arranged such that in each case a predetermined layer height of bulk material from the associated Overflow chamber is the Abzugs stapleer superimposed. It can be provided that all other partitions allow a greater overall layer height on the discharge conveyor than all partition walls upstream in the conveying direction.
  • feed conveyor and take-off conveyor are not arranged in a continuous conveying direction, according to an embodiment of the invention, it is provided that between that at an angle to Abzugstradeer arranged feed conveyor and the inlet chute a bulk material in the feed chamber of the inlet chute conductive saddle is arranged.
  • a geometry opening in the falling direction of the bulk material can be advantageous, in particular when using a plurality of partitions and thus resulting small chamber volume. This means that the housing walls and the partition walls form chambers whose outlet openings are larger than the inlet openings. With this geometry, the formation of bridge formations in the bulk material can be counteracted.
  • the basic shape of the intake chute can be circular and / or curved edge or box-shaped.
  • Fig. 1 is a transfer chute with a single vertical division of the inlet chute with filled first chamber and the withdrawal of the bulk material in a schematic side view
  • FIG. 3 a transfer chute according to FIG. 1 with a feed conveyor arranged at an angle to the discharge conveyor, FIG.
  • FIG. 4 shows a transfer chute according to FIG. 1 including a wear protection formed by bulk material regions.

  • the bulk material 11 falls through the inlet chute 12 onto a saddle 14, from which it is drawn off to the feed chute 13 by the relative speed of the discharge conveyor 15.
  • the maximum bulk material flow 16 to be drawn off is limited by a guide wall 17.
  • a partition 18 is installed, which divides the chute into two chambers, namely a first feed chamber 20 and a downstream overflow chamber 21.
  • the positioning of the partition wall 18 is based on the bulk material properties and is chosen so that in the first task chamber 20 at least the angle of repose of the bulk material 1 1 can adjust. From this condition, the location of the upper edge 23 of the partition 18 is derived.
  • the lower base 24 of the partition 18 determines the layer height 25 of the deducted bulk material 1 1, which is smaller than that through the guide wall 17 maximum permitted layer height 16.
  • Partition 18 for wear In order to reduce this, wear strips are used as wear protection on the upper boundary edge 23 and on the lower base point 24 of the partition wall 18.
  • FIG. 2 illustrates another embodiment of the invention which does not differ in material flow from the embodiment shown in FIG. 1 but has two partitions 18 and 19. Consequently, the inlet chute 12 is divided into the feed chamber 20 and two downstream overflow chambers 21 and 22.

Deviating from the illustrations in FIGS. 1 and 2, for this purpose, an additional saddle 26 is used to divert the bulk material flow directly into the feed chamber 20, which is created by the dividing wall 18 dividing the intake chute 12.
