Definitions

  • the invention relates to a device for loading a shaft furnace for burning and sintering lumpy material, such as limestone, dolomite, magnesite or the like, with granular bulk material, with a top silo arranged above the essentially circular cross-section of the furnace shaft with essentially homogeneously mixed bulk material and one Gout silo outlet for feeding the bulk material onto the surface to be covered of the bulk material column located in the furnace shaft in a distribution that can be controlled via the shaft diameter.
  • lumpy material such as limestone, dolomite, magnesite or the like
  • the invention is therefore based on the object of providing a device of the type mentioned at the outset, which makes it possible in a simple manner to feed the bulk material to be input in the desired distribution over the furnace shaft diameter.
  • this object is achieved in a device of the type mentioned at the outset by an essentially circular plate arranged at a distance below the gas silo outlet, the diameter of which is smaller than the inner diameter of the furnace shaft and larger than the diameter of the outlet opening of the gas silo outlet; and a ring box or the like which can be rotated concentrically to the plate and to which a number of wipers projecting into the bulk material which is sloping on the plate are attached, to which guide slides or the like each ending with their outlet at different distances from the longitudinal center axis of the furnace shaft are permanently assigned .
  • a particularly preferred embodiment of the invention provides that the plate is arranged in a preferably horizontally aligned position.
  • the ring box is controlled by an electric motor or the like, drivable - is _ bar.
  • Another embodiment of the invention is characterized in that the immersion depth of at least one of the wipers in the bulk material located on the plate is adjustable.
  • the invention also proposes, if necessary, that at least one of the guide chutes runs obliquely downwards from the plate or ring box towards the inner wall of the furnace shaft and at least one of the guide chutes runs towards the rest of the surface to be covered.
  • the guide chutes end at a distance above the upper edge of the furnace shaft.
  • Another embodiment of the invention is characterized in that the outlets of the chutes in WE - sentlichen in a horizontal plane.
  • the wipers consist of essentially vertically arranged plates, preferably of sheet metal or the like.
  • the invention also proposes, if necessary, that the wipers from a circumferential point of the ring box located behind the respective guide chute, viewed in the direction of rotation of the ring box, under one of the radius protrude direction rejecting angle up to a position in the bulk material, which is circumferentially within the range of the respective guide chute.
  • the substantially horizontally arranged circular plate is provided below the gout silo outlet in the device according to the invention, the distance of which can be adapted to the grain size of the entire bulk material, can prevent any unwanted outflow of the bulk material from the gout silo with appropriate dimensioning of the plate .
  • the wipers which are evenly distributed around the circumference of the rotating ring box, protrude into the loose material of the bulk material embankment on the plate and the number of which corresponds to the number of circular rings described above and the remaining area, take on rotation of the ring box, whose speed of rotation can be adjusted , equal amounts of material from the plate and the table formed by it and direct the respective bulk material to the respectively assigned guide chute.
  • the guide chutes and the wipers are firmly connected to the ring box and rotate with it.
  • the number of guide chutes and the wipers is the same, with one guide chute being assigned to one wiper.
  • the number of scrapers and guide chutes is equal to the number of circular rings to be covered and the remaining surface of the bulk material surface in the furnace head, the number of circular rings in question depending on the requirement, for example four, but also more or less.
  • Each guide chute is designed in such a way that its outlet sweeps over the associated ring or the remaining surface of the bulk material surface in the furnace head.
  • the already homogeneously mixed bulk material 2 which is constantly offered from a top silo 1 above the shaft furnace, is distributed uniformly in the upper part of the furnace onto a surface 3 with a circular cross section.
  • the circular surface 3 to be covered of the bulk material in the furnace head is in several circular rings 4, 5, 6, 7, each with the same cross-sectional area divided, that is to say into ring surfaces, and an inevitably resulting, centrally arranged residual surface 8 with a circular cross-section, each of the ring surfaces 4, 5, 6, 7 and the residual surface 8 each being assigned the same bulk quantities.
  • a circular plate 10 is arranged horizontally at a distance below a gas silo outlet 9.
  • Wipers 11, which protrude into the bulk material 2 loosely sloping on the plate 10, are fixedly mounted on a rotatable ring box 12, wherein the wipers 11 consist of vertically arranged metal plates, which in the manner shown in FIG. 2 under one of the radius direction protrude different angles into the bulk material 2 so that their ends projecting in the direction of the longitudinal central axis of the shaft furnace lie within that circumferential region of the ring box 12, via which each of the wipers 11 associated guide chutes 14 lead away obliquely downwards from the circumferential edge of the plate 10.
  • the wipers 11 are evenly distributed on the circumference of the ring box 12, their number corresponding to the number of circular rings 4, 5, 6 and 7 and the remaining surface 8.
  • the guide chutes 14 in turn end at their respective outlet above the surface 3 to be occupied at a different distance from the longitudinal central axis of the furnace, with one of the guide chutes 14 thus running out above each of the circular rings 4, 5, 6, 7 or the remaining surface 8.
  • the guide chutes 14 are of course firmly connected to the ring box 12, the number of guide chutes 14 and the wipers 11 being the same.
  • the wipers 11 remove the same amount of material from the plate 10 and guide the bulk material in question to the respectively assigned guide chute 14, which then passes the material to the respective circular ring 4, 5, 6, 7 or the remaining surface 8 respectively.
