Definitions

the invention relates to a top seal for shaft furnaces, in particular blast furnaces, with a feed hopper with a feed tube, a rotating chute support with a rotary drive and a pivotable chute inside the furnace with external drive means.
a generic gout closure is described in German patent application 19709 329.9. This is a bellless top seal, whereby the drives for the rotation and tilting movement of the chute support and the chute work independently of one another and are not connected to the furnace chamber.
the chute carrier which is mounted in a ball bearing slewing ring, has a rotary drive that is composed of an electric motor, pinion and ring gear.
a hydraulic pressure cylinder rotating with the chute carrier is disclosed as the drive means for the tilting movement.
Carrying the tilt drive on the rotating chute carrier of the top seal shows in practical implementation the disadvantage that a complicated, expensive and fault-prone energy transfer to the rotating part is necessary, for example by means of slip rings.
a distribution chute or chute is connected to the lower ends of an inner cylinder and outer cylinder, which are rotatable, axially displaceable relative to one another and are mounted independently of one another.
the distribution chute can be rotated simultaneously with the inner cylinder and outer cylinder and tilted relative to the outer cylinder with the vertical movement of the inner cylinder.
the vertical movement is accomplished with several pressure cylinders.
the distribution chute is at the lower end of the inner cylinder pivoted with the help of pivot pins and connected to the lower end of the outer cylinder by means of joint pieces.
the distribution chute is pivoted by moving the outer cylinder vertically in relation to the inner cylinder.
the drive described is a superimposed rotation and tilting movement of the chute.
the invention has for its object to provide a generic, low-wear, low-wear and inexpensive gout closure.
the drive means for the pivoting movement of the chute comprise at least one motor, which drives a sprocket via a pinion, the sprocket coming into engagement with the spindle gears of at least two spindles distributed over the circumference of the top seal outside the rotating chute carrier Generation of a lifting and lowering movement of the spindles, as well as means for transmitting this vertical movement of the spindles to the tilting shafts penetrating the inner housing wall, into which the chute can be suspended, for producing a swiveling or tilting movement of the chute.
the movement transmission means between the spindles and the chute is a lifting frame and a lifting ring, the lifting frame being carried along in accordance with the vertical movement of the spindle nut and the lifting ring in accordance with the vertical movement of the lifting frame.
Joint pieces are fastened to the lifting ring, which convert the lifting and lowering movement of the lifting ring into a corresponding rotary movement of the tilting shafts by eccentric attack on the tilting shafts.
the tilting shafts have at their first end means for attaching the chute and at their second end an area extending at right angles to the shaft axis for connection to the joint pieces.
three spindles are provided, which ensure a particularly tilt-free drive.
the arrangement of the drive means according to the invention and the choice of drives enable complete synchronization of the lifting spindles and thus an absolutely even, uncanted lifting and lowering of the lifting ring and thus a low susceptibility to failure.
the drive elements remain dust-free, which has an advantageous effect on their service life.
the seals used are no longer able to withstand the full differential pressure between the gas pressure at the furnace head and the atmospheric pressure. set, but only the low preselected differential pressure.
the lid solution it is possible to use nitrogen to build up a gas pressure inside the housing that is slightly higher than the pressure inside the furnace. The pressure can be adjusted automatically.
the seals as they are known from German patent application 197 09 329.9, can be made less expensive. Any damage to the seals leads to an increase in the otherwise very low nitrogen consumption and would be noticed immediately.
Figure 1 is a side view of the top seal
Figure 2 is a front view of the top seal.
Figure 1 shows a top seal with rotatable and tiltable chute 1 for charging a blast furnace.
the Möller is discharged from an infeed bunker into a feed hopper below (shown schematically). From the feed hopper, the Möller reaches a tilting and rotating chute 1 arranged within the chute support and from there into the upper part of the blast furnace via an insertion pipe 2.
the chute carrier 3 with chute is set in rotation by a rotary drive consisting of a motor 4, a pinion 5 and a ring gear 6.
a further motor 7 is provided for the tilting movement and drives a ring gear 9 via a pinion 8.
the drive elements are supported by means of the bearing 10.
the ring gear 9 drives the respective spindle gear 11 of three spindles 13 distributed over the circumference of the top seal housing 12. Due to the rotary movement, the spindle nut rises and falls and takes the lifting frame 14 arranged adjacent to it with it. Adjacent the lifting ring 15 is arranged to the lifting frame. The vertical movement of the lifting frame 14 is transmitted to the lifting ring 15, while a bearing 16 arranged laterally below the lifting ring receives the rotary movement of the lifting ring.
hinge pieces 17 are detachably fastened and supported with their first end 18 (19).
the second end 20 of the joint pieces 17 is releasably attached to a connecting part 21 of the tilting shafts 22.
the joint pieces 17 engage the connecting part 21 of the tilting shafts 22 eccentrically, so that the vertical movement of the lifting ring 15 is converted into a corresponding rotary movement of the tilting shafts 22.
the tilting shafts 22 are mounted in bearings 23. They penetrate the inner wall 24 of the chute carrier 3 in a gas-tight manner.
the inward end 28 of the tilting shafts 22 is designed in such a way that the rotary chute 1 can be suspended. In this case, the chute 1 can be advantageously locked by short-stroke cylinders 25 for safety reasons. With 26 and 27, upper and lower annular seals are designated.
the housing 12 and the drive means can be closed with a cover 29 and can be made gas-tight.
the internal pressure can be checked by adding nitrogen.
