  • a charging device for a furnace such as a blast furnace is composed of a spreader element centrally arranged in an inlet within the head of the furnace.
  • the spreader element is mounted for both rotation about the axis of the furnace and angular adjustment with respect to the axis.
  • Feed mechanisms including charging sluices are disposed above the furnace and the spreader element to supply the charging load.
  • a drive mechanism is connected to the spreader element to provide the rotary and angular. displacements during the charging operation. Controlled movement of the spreader element provides a more uniform distribution of the charge within the furnace.
  • the charging process is accomplished simply and accurately in either a continuous or discontinuous fashion.
  • FIG. 3 is a cross-sectional view of 'the transmission for the driving system shown in FIG.'2.
  • FIG. 4 is a partially'sectioned view of a second embodiment of the novel charging arrangement according to the present invention.
  • FIG.'1 shows the upper portion or head of a modern, high-production furnace, generally designated I, having a throat of large diameter.
  • the particular furnace shown is a blast furnace-altemately charged through two or more charging sluices 2, 2 and a distributing device to be described in greaterdetailbelow.
  • blast furnace charging load is alternately fed to the charging sluices 2, 2' by a suitable conveyor'such as conveyor belt 5 and a reversible spreader element 6.
  • the charging load passes from the conveyor belt 5 through two or more tubs or skips 4, 4 and charging hoppers 3, 3 to the sluices 2, 2.
  • Each of the charging sluices 2, 2' is equipped at its inlet and exit with suitable doors 7 and 10 respectively.
  • the doors are open and closed at given times during the charging cycle to allow material to pass into and from the sluices.
  • the charging sluices 2, 2 are equipped in a conventional manner. with intake and outlet valves 8, 8.
  • the release of the furnace charging load from each of the charging sluices 2, 2' is accomplished through the exit door 10 which when opened is completely removed from the path of the charging materials.
  • An adjustable throttle element 11 controls the feed rate of the charging load into the furnace.
  • the throttling of the charging load is only possible, however, for charges of uniform grain size. Where the grain size is irregular, it may be more advantageous to provide other feed control means in place of the throttling element, for example discharge spouts or launders.
  • the charging loads issuing from the charging sluices .2, 2', respectively, are directed into a stock hopper l2 and pass from the hopper through a fixed, vertical spout 13 to an adjustable spreader or chute l fitted within thefumace head.
  • the ratio of the inside dimensions of the feed spout 13, that is the length to diameter ratio should be so selected that the load strikes the adjustable spreader chute 15 from an approximately vertical direction.
  • the adjustable chute 15 is fitted within the furnace head in such a manner that it can rotate about the vertical axis of the blast furnace and be adjusted angularly with respect to the axis at the same time.
  • the chute 15 can be angularly adjusted between positions 18, 18', 18" and 19 to distribute the stream of charging material throughout the plane of the furnace at the stocking level, such as shown for example at 20. It is thus possible to reach any portion of the stocking level plane by suitable rotation and angular adjustment of the spreader chute 15.
  • the charging load can be distributed in concentric rings or in spirals produced by continuous adjustment'of the angular setting as the spreader chute 15 is rotated. Particular points to be fed in the stocking level plane can also be selected.
  • the size of the discharge opening in a sluice may be regulated in accordance with the particular angular position of the spreader within the furnace.
  • the heighth of the stocking level within the furnace can be measured in a conventional fashion by feeler gauges 17, 17' between each of two charging operations. Owing to the absence of the lower bell and as sociated hopper of the prior art charging devices, the feeler gauges can be distributed circumferentially around the blast furnace at a number of azimuthal posi tions with respect to the vertical axis of the furnace. Similarly, automatic load controlling devices can be disposed at different levels in the furnace throat for monitoring the charging process.
  • the spreader chute 15 in accordance with the present invention is attached to the blast furnace head 1 by means of a flange joint 23 for simple and rapid detachment. With this flange joint, the whole spreader can be detached and removed by means of a suitable suspension gear 21 and a crane installation.
  • FIG. 2 shows the inlet spout l3 and a novel driving arrangement for the spreader chute 15.
  • the driving furnace means according to the present invention is so arranged that only rotating shafts of small diameter are required to be sealed at the interface of the spout 13 with the external atmosphere.
  • the actual drive system incorporates a rotating cylinder or bush 25 having rotating ring 26 at its lower end from which the spreader chute 15 (shown in two orthogonal positions) is pivotally suspended on two brackets 27 by suitable connecting pins 28.
  • the rotating'bush 25 is connected by means of a ball bearing 29 with the fixed inlet spout '13.
  • Bearing 29 allows spreader chute 15 to be rotated by drive means such as described hereinafter.
  • an actuating rod 30 is connected to the chute 15 and moves together with its actuating sleeve, 31 in the vertical direction.
  • the actuating rod 30 and sleeve 31 are linked by a cam-following roller 34 to a second rotating sleeve 32 concentrically mounted with respect to the rotating bush 25.
  • the sleeve 32 is also linked with the rotating bush 25 by means of a ball bearing 35.
  • the rotating sleeve 32 has a sinusoidal camming slot 33 in which the roller 35 is engaged.
  • rotation of the sleeve 32 with respect to the follower 34 produces a vertical displacement of connecting rod 30 and an angular displacement of the spreader chute 15.
  • the sleeves or bushes 25 and 32 are rotated by gears 38 and 39 respectively.
  • the gears 38 and 39 are suitably actuated by an externally located driving mechanism.
  • the movements of the various driving elements for spreader chute 15 are all accommodated within the fixed housing 36.
  • the housing 36 is attached in a gastight manner to the inlet of blast furnace head 1 (FIG. 1) and to the intake spout 13 by means of detachable connections.
  • the sealing problems are advantageously reduced to a minimum compared with the charging arrangements of the prior art.
  • an inert gas such as nitrogen may be introduced through the pipe 37 into the housing 36.
  • nitrogen helps to scavenge the spaces between different moving parts.
  • a lubricating fluid may be sprayed on the moving parts in conjunction with the cooling gas to provide continuous lubrication of the moving parts.
  • FIG. 3 shows the transmission of the driving or actuating means for the spreader chute 15.
  • the main driving motor 41 operates through a clutch 43; braking device44; transmission gearing 45, 46; drive shaft 47 and a ring gear 48 to drive the internally located rotating sleeve 25.
  • Motor 41 similarly drives a planetary transmission 49 comprising ring gear 50 and two planet gears 51, 52.
  • the planet gears 51, 52 are in turn coupled through gear train 53 to drive shaft 54 and its associated ring gear 55.
  • Ring gear 55 is connected to and drives the external rotating sleeve 32.
  • the rotational speed of the planet gears 51, 52 in the planetary transmission 49 can be varied by means of an auxiliary drive motor 42.
  • Motor 42 is connected by means of clutch 57 and gear train 58, 59 to the central sun gear of the planetary transmission 49. Since the planetary transmission 49 serves as a differential drive, the operation of motor 42 changes therotational speed of gear train 53 and ring gear 55 so that the speeds of sleeves 25 and 32 are no longer synchronized.
  • the variation in speed depends on the speed of motor 42.
  • the angular setting of the spreader chute 15 with respect to the vertical axis of the blast furnace is varied when synchronism between the rotations of sleeve 25 and 32 is lost.
  • the spreader chute 15 continues to rotate with motor 41 but at a new angular setting. Similarly, after the main driving motor has been stopped, the non-rotating spreader chute 15 can be set at different angular positions by means of the auxiliary drive motor 42.
  • An angular setting indicator 60 allows the angle of the spreader chute to be directly monitored and controlled. Limit stops may be fitted in the indicator 60 to prevent the spreader chute 15 from being moved outside preset extreme angular positions.
  • the novel driving arrangement allows the housing 36 which is exposed to the full pressure of the furnace throat to be very simply and effectively sealed since there are only two small diameter drive shafts 47 and 54 which must be sealed at the walls of housing 36.
  • FIG. 4 An alternate embodiment of the charging arrangement according to the present invention is shown in FIG. 4.
  • a double spreader chute 61 is used to distribute the charging load in a manner similar to that disclosed in the embodiment of FIG. 1.
  • the charging load is alternately fed to the chute 51 through sluices 62, 62' the stock hopper 63 and the feeder 64.
  • the double spreader chute 61 is rotated by means of a hollow shaft 66 passing through a centrally located cylindrical bush 65.
  • the chute 61 and the shaft 66 are rotated by an external means not shown in the figure.
  • Continuous variation of the angular setting of the double spreader chute 61 is effected by means of a connecting rod 67 centrally located in the hollow shaft 66.
