  • the distributing plate of the apparatus facilitates to shifting the position of charge disposal in a blast furnace, so that the surface of the deposited charge will be even.
  • the present invention has been developed in order to obviate above mentioned defects observed in the conventional apparatuses.
  • FIG. 3 is a plane view of FIG. 2;
  • FIG. 5 is a diagram showing the side view of a modification of the driving mechanism
  • FIG. 7 shows another modified driving system, FIG. 7(a) being a diagram showing a side view thereof, and FIG. 7(b) being a diagram showing a front view; and
  • the reference numeral 1 represents a lower bell of a blast furnace, and 2 is a blast furnace wall.
  • An opening 3, shown in FIG. 2, is formed at a position located below the lower bell l and above the line where the charge is deposited, said opening 3 having a diameter which is large enough to let the operator pass.
  • the rear end portion of the opening 3 is covered by a removable cover 4 to keep it airtight.
  • Upper and lower brackets 5 and 6 respectively are provided securely on the inner side of the blast furnace wall 2 adjacent the circumference of said opening 3.
  • An upper rail 7, FIG. 2 is disposed horizontally below but adjacent said upper bracket 5 and a pair of lower rails 8,8 are provided above but adjacent said lower bracket, in parallel with said upper rail 7.
  • a driving system 13 secured adjacent said cover 4 comprises a cylinder 14 and a piston 15, and a piston rod 16 penetrates the cover 4 to connect with the rear of the carrier at its forward end, whereby the piston 15 actuated by suitably adjusted fluid pressure in the cylinder will drive the carrier 9 horizontally along the rails 7, 8 and 8.
  • Said brackets 5, 6 should be disposed at a position where they will not come in contact with the charge. It is also desirable for the upper and lower brackets to provided with heat resistant panels 5, 6' each at the upper and lower surfaces respectively in order to protect the movable part of the carrier from high temperature gas in the blast furnace.
  • the distributing plate 10 may be provided with selflining at a portion which receives the impact of the charge, and with a replaceable lining at a portion which reaches inner most part of the blast furnace to give a longer life to the plate. Care should be taken in respect to the shape and the materials for the rails 7, 8 and 8' secured to the brackets 5, 6 so that neither high temperature gas in the blast furnace nor dust of the charge should accumulate thereon. It is still desirable to render said rails replaceable by employing generally used binding or mounting means.
  • the charge distributing apparatus of the above mentioned structure will be provided in a suitable number along the circumference of the blast furnace. Each of said charge distributing apparatus is actuated in accordance with a predetermined schedule, and one each alternatively will be driven to a predetermined position in the horizontal direction when the charge is dropped.
  • FIG. 1(a) illustrates the distributing plate 10 when it is advanced furthermost in the blast furnace. At this position, the charge introduced from the lowerbell 1 will bump against the charge distributing plate 10 to alter its direction toward the center of the blast furnace where the charge is to be deposited. Thus, by shifting the position of the distributing plate backward from said most advanced position, the position of the charge disposal will concurrently be shifted from the center to the wall of the blast furnace.
  • the driving system is not limited to such as aforementioned.
  • the carrier 9 may be driven by an arrangement comprising, as in FIG. 5, link 18 which is connected with the carrier by means of a connecting rod 17 which is connected to the carrier, a fanshaped gear 20 which is connected securely to the shaft 19 of the link 18, a pinion 21 engaging with said gear, and a suitable power source actuating the rotation of said pinion.
  • link 18 which is connected with the carrier by means of a connecting rod 17 which is connected to the carrier
  • a fanshaped gear 20 which is connected securely to the shaft 19 of the link 18, a pinion 21 engaging with said gear
  • a suitable power source actuating the rotation of said pinion.
  • a replaceable resilient board (22) may be provided atop the upper face of the distributing plate 10 in order that the energy generated by the impact of the charge against the distributing plate may be utilized to increase the efficiency of the operation.
  • gliding member 23 that is smaller in abrasive resistance may be used with the carrier (FIG. 7). It is also possible to attach the wheels 11, 12 on the brackets 5, 6 (FIG. 8).
  • the distributing plate is shown as being horizontal and is designated 10'.
  • the charge distributing apparatus for blast furnaces in accordance with the present invention comprises, as aforementioned, a charge distributing plate which is disposed at a position below the lower bell and above the deposited charge surface and which is slanted at an arbitrary angle, a guiding member to guide said distributing plate horizontally which is securely fixed to the blast furnace wall, and a driving system to drive said distributing plate back and forth along said guiding member.
  • the distributing plate driven by the driving system horizontally along the guiding member will enable the position of the charge disposal in the blast furnace to shift, so that the surface of the deposited charge will be even; it is therefore unnecessary to provide a rotating member or a suspending beam of the conventional apparatuses for the distributing plate for the purpose of changing its angle, whereby the apparatus can be rendered of simple structure and yet solid; and effective use of the blast furnace space is assured because not much space is required for the installation of the distributing plate.
