Definitions

  • the invention relates to a device for scattering bulk material, comprising a distribution chute with a task area and a discharge area, wherein the Verteilerschurre is rotatable about an in mounting position in the weight direction of the bulk material vertically extending central axis and inclined with respect to this central axis at an angle, the distribution chute a in the direction of rotation, the front side forming the first leading longitudinal side and, with respect to the direction of rotation trailing, second longitudinal side and wherein at least the second longitudinal side forms the discharge side of the distribution chute.
  • EP 0 343 466 B1 describes a device for the uniform distribution of material on a circular surface by means of an inclined rotary chute, the angle of inclination of which is adjustable.
  • the device is used for distribution of bulk and giant-shaped materials in the form of dust, grains, powders or other form, which are placed in successive uniform layers in a generally cylindrical space. Since it is important in such applications to distribute the materials uniformly in a circle, EP 0 343 466 B1 proposes a special geometry for the distribution chute of the device.
  • the distribution chute has a long flat sliding surface with a straight line with respect to the direction of rotation of the front of the chute forming the first longitudinal side, which is provided with a retaining edge, while the opposite second longitudinal side forms the discharge side.
  • the discharge side forming longitudinal side is designed approximately S-shaped. This design takes into account the fact that the amount of material dropped at the end of the chute must be greater than the amount that falls from the top of the chute to the center, as the linear velocity of the chute increases from the center to the periphery, so that the per Time unit of the chute covered area increases proportionally to the square of the radius.
  • the chute geometry described in EP 0 343 466 B1 is advantageous with regard to the most uniform possible scattering distribution of the bulk material.
  • the device has the disadvantage that the chute geometry can not be calculated in advance in order to achieve optimum scattering behavior or distribution behavior, since various influencing factors, material properties and interactions between the material and the surface of the chute can not be mathematically described with sufficient accuracy, depending on the application.
  • the invention is therefore based on the object to improve a device of the type mentioned so that the most uniform distribution of the bulk material can be achieved even with changing operating conditions and / or changing material properties.
  • the object underlying the invention is achieved by a device for scattering bulk material, comprising a distribution chute with a task area and a discharge area, wherein the Verteilerschurre rotatable about an installation position in the direction of weight of the bulk material vertically extending central axis and inclined with respect to this central axis at an angle is, wherein the distribution chute in the direction of rotation forming the front first leading longitudinal side and, with respect to the direction of rotation trailing, second longitudinal side and wherein at least the second longitudinal side forms the discharge side of the distribution chute.
  • the device according to the invention is characterized in that the distributor chute is transversely displaceable with respect to the vertical center axis.
  • Such a transversely displaceable mounting of the distributor chute allows the displacement of the application point in the task area of the distribution chute.
  • the material flow occurring from a feed chute onto the distributor chute can impinge more or less outside the central longitudinal axis of the distributor chute onto the feed area, so that the distance of the material flow to the discharge side is more or less large. In this way, the particle trajectory of the sliding over the chute coal flow can be targeted influence.
  • the distributor chute is pivotably mounted about its longitudinal axis.
  • the bank of the Verteilerschurre is adjustable.
  • the angle of inclination of the distributor chute is adjustable relative to a horizontal scattering plane.
  • it makes sense to design the device so that the rotational speed of the distributor chute is variable.
  • the task area of the distribution chute is curved in the longitudinal direction. This makes it possible to operate the chute with a smaller inclination, wherein at a constant chute length a larger distribution area can be covered. Due to the curvature of the chute in the application area, there is achieved a lower delay of the material flow than in the discharge area, without it being necessary for this purpose to change the angle of attack of the distributor chute with respect to a horizontal.
  • the distributor chute is heated. This will prevent material caking on the chute surface. This also contributes to an optimized distribution behavior, disturbances of the particle - trajectory of the material due to moisture-related caking are avoided.
  • the distributor chute is formed as a hollow profile at least in the region of its sliding surface.
  • the distribution chute may be connected to a steam supply.
  • At least one steam connection is provided on a distributor designed as a rotary joint, which is arranged in the vertical center axis of the device in the installation position.
  • the distributor may be arranged with respect to the distribution chute rotatably and rotate with the distribution chute with respect to a fixed laid steam supply line.
  • the distribution chute further comprises a condensate drain, which is also connected to the manifold.
  • Figure 1 is a greatly simplified perspective view of the device according to the
  • FIG. 2 A view from the direction of the arrow III. in FIG. 2
  • the device according to the invention comprises a designated 1
  • Distribution chute which is connected via a bracket 2 rigidly connected to a turntable 3.
  • the turntable is provided with drive means, not shown, via which it is offset with the attached distributor chute 1 about a vertical axis 4 in uniform rotations.
  • the turntable 3 can be provided for this purpose with a circumferential, not shown toothing, which cooperates with a drive pinion of an electric motor.
  • the direction of rotation of the arrangement is illustrated by the arrows drawn in FIGS. 1 to 3. In the illustrated embodiment, the Verteilerschurre 1 rotates clockwise.
  • Zugarschurre 5 is centrally located, via which pourable material, such as wet raw lignite coal is placed on the distribution chute 1.
  • pourable material such as wet raw lignite coal is placed on the distribution chute 1.
  • the central longitudinal axis of the feed chute 5 is congruent with the vertical axis of rotation 4 of the distribution chute 1.
  • the distributor chute 1 is inclined in total with respect to a horizontal straightening plane by the angle ⁇ .
  • the inclination angle ⁇ of the distributor chute 1 is adjustable.
  • an angle of inclination ⁇ relative to a horizontal straightening plane of the distributor chute is adjustable in various stages in a known manner.
  • the distribution chute 1 is provided on its side facing away from the chute surface 6 with counterweights 10.
  • Distribution chute 1 with counterweights beyond a relief of the storage of the distribution chute 1 is effected in an advantageous manner.
  • the center longitudinal axis of the distribution chute is designated. This is located in the drawn in Figure 1 representation of the distribution chute with respect to the vertical axis of rotation 4 in the neutral position.
  • Neutral position means that the vertical axis of rotation 4 and the central longitudinal axis 11 of the distributor chute intersect so that the material flow impinges centrally in the feed region 12 of the distributor chute 1.
  • the distribution chute 1 can be transversely adjusted from this neutral position, so that the task point in the application area 12 of the distribution chute 1 with respect to the central longitudinal axis 11 of the distribution chute 1 emigrated.
  • the task point can either be adjusted closer to the restraining edge 9 or closer in the direction of the discharge edge 7.
  • the bank of the distributor chute 1 about the central longitudinal axis 11 is adjustable, so that depending on the bank more material in the upstream region of the discharge edge 7 or more material in the downstream area of the discharge edge 7 is dropped. If the bank of the distribution chute 1 adjusted so that this slope in the direction of the discharge edge 7, more material in the upper, upstream region of the discharge edge 7 is dropped. On the other hand, if the bank is adjusted in such a way that the slope is in the direction of the retention edge, more material is thrown off in the downstream area of the discharge edge 7.
  • the application region 12 is curved in the direction of the central longitudinal axis 11 of the distributor chute 1, so that the angle of inclination ⁇ relative to a horizontal straightening plane in the application region 12 of the distributor chute by the amount of in FIG 2 drawn angle ß is greater.
  • the material flow experiences a lower delay in the feed area 12, which makes it possible to select the inclination angle ⁇ of the distributor chute 1 as a whole smaller.
  • the feed area 12 of the distributor chute 1 does not necessarily have to be curved, but the change in the angle of inclination can also be discontinuous.
  • the distributor chute 1 is double-walled, at least in the region of the chute surface 6, and flows through with steam as the heating medium.
