Embodiment Construction

[0021] figure 1 A perspective view showing a metering device 10 for bulk material according to a preferred embodiment of the present invention. A wear-resistant cone 12 of the storage chamber 14 terminates in a cylindrical outlet channel 16 (not shown) upstream and above the blast furnace. The metering device 10 is placed below the storage chamber 14 in a closed housing 17 (indicated in the figure by two wall sections) between the storage chamber 14 and the blast furnace. Beneath the bottom end of the aforementioned cylindrical outlet passage 16, the metering device comprises a first or upper gate 18, and a second or lower gate 20 located below the upper gate 18 (see also Figure 7 ). Two shafts 24 and 26 provided on each side of the gates 18 and 20 support the two gates; and allow the two gates to rotate about a common axis of rotation 25 (see also image 3 ). figure 1 not shown in , but in Figure 4 ~ Figure 6 A drive mechanism, shown as assembly 27, drives the two shaf...

Abstract

The invention concerns a device for dosage of (10) materials, comprising first (18) and second (20) rotary registers. Shafts (24, 26) arranged on either side of the registers (18, 20) support the two registers and enable them to rotate about a common axis of rotation (25). One first (24) shaft is arranged on one side of the two registers (18, 20), and a second shaft (26) is arranged on the opposite side. A driving mechanism is connected to the shafts (24, 26) to rotate the two registers (18, 20) in opposite directions. Each rotary register (18, 20) is maintained by a first suspension arm (28, 30) and by a second suspension arm (32, 34), which extend on either side of the respective register. The first shaft (24) and the second shaft (26) are driven in opposite directions by the driving mechanism. The first suspension arm (28) of the first register (18) is removably attached to the first shaft (24) and the first suspension arm (30) of the second register (20) is removably attached to the second shaft (26). The second suspension arm (32) of the second register (20) is connected in articulation to the first suspension arm (28) of the first register (18) and the second suspension arm (34) of the first register (18) is connected in articulation to the first suspension arm (30) of the second register (20).

Description

technical field [0001] The invention relates to a metering device for loose materials, in particular to a device for metering loose materials for blast furnace charging. Background technique [0002] For example, in patent application EP-A-0062770, a metering device for such bulk materials is disclosed; this device cooperates with the outlet of a storage hopper mounted on the top of the blast furnace. The metering device is concentric with the axis of the blast furnace; and, in a closed casing, comprises two gates in the form of spherical sectors with V-shaped cutouts, one above the other. One end of the two gates is supported on the same pivot and can freely rotate around the pivot. This pivot is supported on a first bearing of the closure housing. On the diametrically opposite side of the first bearing, a shaft integral with the upper gate is placed within and concentric with the quill; and the quill is integral with the lower gate overall.
