Definitions

  • the invention relates to a top closure for shaft furnaces, in particular Blast furnaces, with a feed hopper with a feed pipe, a rotating one Chute carrier with rotary drive and a swiveling chute inside the furnace with external drive means.
  • a generic gout closure is in the German patent application 197 09 329.9. This is a bellless one Gout closure, the drives for the rotation and tilting movement of the Chute carrier and chute work independently and not in Connected to the furnace room.
  • the one mounted in a ball slewing ring Chute carrier has a rotary drive that consists of an electric motor, Sprocket and sprocket put together.
  • As a drive for the tilting movement is a hydraulic pressure cylinder that rotates with the chute support disclosed.
  • OS 2404647 describes a device for driving or moving a Device for loading a blast furnace with raw materials known.
  • a distribution chute or chute with the lower ends of an inner cylinder and outer cylinder connected, which at the same time rotatable, relative to each other axially displaceable and are mounted independently of each other.
  • the Distribution chute is simultaneously with the inner cylinder and outer cylinder rotatable and with the vertical movement of the inner cylinder relative to the outer cylinder tiltable. The vertical movement is accomplished with several pressure cylinders.
  • the distribution chute is at the lower end of the inner cylinder with the help of pivot pins pivoted and with joint pieces with connected to the lower end of the outer cylinder.
  • the distribution chute is pivoted by the outer cylinder vertically relative to the inner cylinder is moved.
  • the drive described is a superimposed one Rotation and tilting movement of the chute.
  • GB-A-2027860 describes a loading device for shaft furnaces with a Rotating sleeve and a tilting chute known. For this tilting movement one operating rod articulated on the rear part of the chute, whereby the Chute is pivoted around its horizontal suspension bearing. This Actuating rod rotates together with the rotating sleeve.
  • the invention is based on the object a less prone to failure, low wear and cost-effective To create gout closure of the generic type.
  • the drive means for the pivoting movement the chute comprise at least one motor, each via a pinion Drives ring gear, the ring gear with the spindle gears from at least two over the circumference of the top seal outside of the rotating one Chute carrier distributed spindles engages to generate a lifting and lowering movement of the spindles, the spindles being fixedly arranged on the piercing gout closure housing; funds are also earmarked for the transfer of these vertical movement of the spindles to the penetrating the inner housing wall Tilting shafts, in which the chute can be hooked, to generate a Swiveling or tilting movement of the chute.
  • the movement transmission means between the spindles and the chute it is a lifting frame and a lifting ring
  • the Lift frame according to the vertical movement of the spindle nut and the Lifting ring taken along according to the vertical movement of the lifting frame becomes.
  • Joint pieces are attached to the cam ring, which are eccentric Attack on the tilting shafts the lifting and lowering movement of the lifting ring in convert a corresponding rotary movement of the tilting shafts.
  • the tipping shafts at their first end means for attaching the chute and on at its 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 drive means are proposed for the rotating and swiveling movement of the chute carrier or to seal the chute with a lid that is placed on the housing becomes.
  • the resulting interior is preferably filled with nitrogen.
  • the drive elements remain dust-free, which is advantageous whose lifespan affects.
  • the drive means are less accessible, the seals used are no longer the full differential pressure exposed between the gas pressure at the furnace head and the atmospheric pressure, only the low preselected differential pressure.
  • the lid solution it is possible to use nitrogen inside the case build up a gas pressure 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, less elaborate. Lead any damage to the seals to an increase in the otherwise very low nitrogen consumption and would noticed immediately.
  • Figure 1 shows a top seal with rotatable and tiltable chute 1 for loading of a blast furnace.
  • the Möller becomes a sluice bunker in an infeed hopper underneath (shown schematically) is discharged. From the feed hopper, the Möller arrives via a feed pipe 2 on a tiltable and rotatable arranged within the chute carrier Chute 1 and from there to the upper part of the blast furnace.
  • the chute carrier 3 with chute is made up of a rotary drive consisting of a motor 4, a pinion 5 and a ring gear 6 set in rotation.
  • a further motor 7 is provided for the tilting movement drives a ring gear 9.
  • the drive elements are by means of the bearing 10 stored.
  • the ring gear 9 drives the respective spindle gear 11 out of three the circumference of the top housing 12 distributed spindles 13. by virtue of the rotational movement raises and lowers the spindle nut while taking it the lifting frame 14 arranged adjacent to this. Adjacent the lifting ring 15 is arranged to the lifting frame.
  • the vertical movement of the Lifting frame 14 is transferred to the lifting ring 15, while a laterally below of the cam ring arranged bearing 16, the rotational movement of the cam ring receives.
  • the second end 20 of the hinge pieces 17 is releasably attached to a connecting part 21 of the tilting shafts 22.
  • the attack of the Joint pieces 17 on the connecting part 21 of the tilting shafts 22 are eccentric, so that the vertical movement of the cam ring 15 in a corresponding Rotational movement of the tilting shafts 22 is converted.
  • the tilting waves 22 are in Bearings 23 stored. They penetrate the inner wall 24 of the gas-tight Chute carrier 3.
  • the inward end 28 of the tilting shafts 22 is like this designed that the rotary chute 1 can be attached.
  • 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 gas-tight.
  • the internal pressure can be checked by adding nitrogen.
