Definitions

the present invention described relates to a loading device for the alternate filling and distribution of solids of two grain classes in shaft furnaces.
Feeding devices for blast furnaces or other shaft furnaces to achieve special loading effects are known.
the subject of EP-Al-0 196 486 is e.g. a loading device on a shaft furnace by means of which the separation should be counteracted when loading.
the device consists of a main silo, which is tightly and rotatably mounted on the furnace and which itself carries at least two further preliminary silos. All silos contain mix internals.
the material to be loaded is introduced from the main silo via a rotating distribution device that protrudes into the shaft furnace.
a concentric feed pipe for the load is also described in the main silo. The diameter of this feed pipe corresponds at least to the diameter of the shaft opening. This arrangement is also intended to prevent feed segregation.
EP-Al-0 215 135 likewise describes a device for loading a shaft furnace by means of which, among other things, segregation is to be avoided.
the above-mentioned device for loading granular bulk material has a top silo arranged above the furnace shaft and a top silo outlet for loading the bulk material.
An essentially circular plate arranged below the gas silo outlet shows a diameter 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.
a number of scrapers protruding into the bulk material that is sloping on the plate are attached to the rotatable ring box, which is arranged concentrically to the plate. to which guide slides ending with their outlet at different distances from the longitudinal central axis of the furnace shaft are assigned.
the feeding device for alternately filling and distributing solids of two grain classes in shaft furnaces is characterized by - A conveyor system that feeds into the shaft opening and works discontinuously, at least in terms of material, and through a distribution screen provided in the shaft under the centrally arranged shaft opening with a centrally located rotary flap to be operated from the outside, wherein the diameter of the rotary flap is matched to that of the shaft opening and the inner diameter of the distribution screen and 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.
the loading device mentioned can further be characterized in that the shaft furnace, the shaft opening for loading, the rotary flap above the distribution screen and the screen itself have a round cross section; the distance between the outer edge of the screen and the inner wall of the shaft is preferably 15 ⁇ 1.5% of the inner diameter of the shaft.
the shaft opening has a guide cylinder 2.3 with an end ring 2.4, and the rotary flap 2.5 to the distribution screen 2.6 is arranged above and has the same a diameter adapted to the central opening in the screen.
the method according to the invention for alternately feeding and distributing solids of two grain classes in shaft furnaces using the loading device mentioned is characterized by the following steps: - At least material discontinuous loading of the shaft furnace with solids of two grain sizes and - setting the rotary flap according to the loading phase, whereby the distribution of the material can be controlled centrally or peripherally depending on the grain class.
FIG. 1 shows a schematic representation of the basic arrangement of the loading device according to the invention: 1.2 is the (loaded) loading bucket with a 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.
FIG. 2 shows a preferred embodiment of the invention, also schematically: the loading, which can take place, for example, by means of baskets, buckets or else belts, tippers, is not shown here.
2.2 is a vertically displaceable closure part for closing the shaft opening.
a Guide cylinder 2.3 provided with end ring 2.4.
the rotary flap 2.5 is arranged above the distribution screen 2.6.
the distribution types can be influenced by - proportions of the materials of the different grain classes in the buckets or on the conveyor belts, - Diameter ratio of rotary flap and distribution screen, and - Batch sequences of materials of different grain classes.
