Definitions
- the invention relates to a device for belt loading with an elevated Back pressure operated blast furnace, with a conveyor belt for continuous Feeding in from Möller, aggregates and mainly coke as a reducing agent existing feedstocks for the bell-gout closure of the blast furnace and with feeding devices above and inside the bell-gout closure on the task and material distribution of the input materials on top of each other bells of different sizes arranged in a buffer bunker.
- the blast furnace feedstocks make up 2.0 to 2.5 times the weight of the Pig iron production from. Characteristics of the unloading, bunker, feeder required here and payment systems are therefore high performance with the greatest possible Mechanization. Transport devices are used here under payment systems understood the feedstock to the top of the blast furnace transport to the top seal arranged there.
- Known transport devices are bucket loading (lowering bucket or tilting bucket (Skip)) with inclined winding or belt inspection with a rotating conveyor belt, which is designed as an inclined or vertical conveyor.
- bucket loading lowering bucket or tilting bucket (Skip)
- inclined winding or belt inspection with a rotating conveyor belt, which is designed as an inclined or vertical conveyor.
- rotating conveyor belt which is designed as an inclined or vertical conveyor.
- the input materials are at the upper end of the Gout closure tipped into an upper funnel, the bottom through an upper one small bell is complete.
- the little bell that falls poured material into a large funnel arranged underneath, through a lower large bell is complete.
- top seals for high-performance blast furnaces with counter pressure operation is the company brochure: "Our partner is World -GHH-IHI top seal for high-performance blast furnaces with counter pressure operation ", Gutehoffnungsdazzling Sterkrade Aktiengesellschaft, 4200 Oberhausen-Sterkrade, PO Box 103.
- a vertical outlet pipe which extends the outlet opening downwards and with the feature that the outlet pipe with a partial length in the funnel-shaped Rotary distributor protrudes, achieved that the Accumulate feed materials and on the sloping walls of the rotary distributor builds up a bulk material slope.
- This bulk material slope is not just one simple and effective wear protection of the side walls of the rotary distributor represents, but also favors due to the frictional conditions brought about by them a largely homogeneous discharge of the input materials in your Discharge down the sloping side walls of the rotary distributor into the buffer bunker.
- the rotary distributor is geometrically designed so that it can be used with any Rotary position with its filling cross section always below the outlet opening of the Fixed feed chute or one arranged above the rotary distributor this subordinate feed hopper. It follows that one round filling cross-section the opening radius of the filling cross-section and accordingly in the case of an angular filling cross section, the distance of its outer edge from its axis of rotation is at least the distance between this filling outlet opening and corresponds to the vertical axis of the round buffer bunker.
- the rotary distributor located below the fixed feed hopper is over Guide rollers on the inside of the bunker wall and a guide on the Central tube of the top seal supported horizontally, while the vertical Support is realized via the bunker cover.
- the rotary distributor is driven by means of suitable drive devices which on the circumference and / or on the axis of the rotary distributor with it in operative connection stand.
- suitable drive devices which on the circumference and / or on the axis of the rotary distributor with it in operative connection stand.
- This side Moving the outlet opening 11 'causes the feed materials 30 to be dependent from the rotational speed of the rotary distributor 10 and the outlet speed the feed materials 30 in the desired manner homogeneous and evenly on the small bell 2 and within the buffer bunker 6 up to whose side walls 18 are distributed.
- the outlet speed is thereby determined by the friction on the sloping side walls of the Rotary distributor 10 and their inclination.
- the horizontal support of the rotary distributor 10 on the central tube of the bell-gout closure 1 is shown schematically by a guide 17.
- the remaining horizontal and vertical supports as well as the drive device of the rotary distributor 10 are not shown.
- the axis of rotation 15 and the filling cross section 13 of the rotary distributor 10 are arranged or designed such that at Each rotational position of the distributor 10 is part of the filler cross section 13 is located below the outlet opening 26, so that no material on the rotary distributor 10 falls into the buffer bunker 6.
- FIGS. 3 and 4 show possible embodiments of an inventive one Rotary distributor shown schematically in individual representation.
- the one in Fig. 3 Rotary distributor 10 shown in FIG. 2 has a round filling cross section 13 and a lower round outlet opening 11 '.
- the outlet opening 11 ' is down and extended inwards by an outlet pipe 11.
- the extension of the outlet pipe 11 causes the feed materials 30 in the from the sloping side walls 19, 19 'and the inwardly projecting outlet pipe part Gusset the feed materials 30 (the feed materials are not shown) and form a bulk material slope on the sloping side walls 19.
- the rotary distributor 10 Due to the lateral displacement of the outlet opening 11 'with respect to the center of area 14 (center of the circle) of the filling cross section 13 is the rotary distributor 10 formed with unevenly sloping side walls 19, 19 ', so that on the steeper Side walls 19 'will deposit less material than on the flatter ones Sidewalls 19.
- To such unevenness in the formation of the Prevent bulk material embankment is on the flatter side wall 19 of the Rotary distributor 10 opposite side 19 'of the outlet pipe 11 with a half-shell pipe part 12 extended inwards so that more material is retained here and the bulk material embankment is evened out overall.
- FIG. 4 shows a square rotary distributor as a further possible design variant 20 shown.
- the outlet opening 11 ' is laterally opposite the center of area 24 of the filler cross section 23 are arranged offset so that also give differently sloping side walls 29, 29 '. From the same Reasons as in the round rotary distributor 10 described above therefore also with the angular rotary distributor 20, the outlet pipe 11 to the inside a half-shell pipe part 12 on the steep side wall 29 'extended.
- the axis of rotation of this angular rotary distributor 10 (the axis of rotation is not drawn) runs so that the side edges 22 of the differently inclined Side walls 29, 29 'are always below the outlet opening one above of the rotary distributor 10 arranged bunker or funnel, so that none Material can fall past the rotary distributor 10 onto the small bell 2.
- the axis of rotation does not necessarily have to be through the center of gravity 24 of the filler cross section 23 be guided.
- the invention is not restricted to the exemplary embodiments shown, but with regard to the geometry and design of the rotary distributor and its Arrangement above the small bell variable to prevailing conditions customizable.
