Definitions

  • the invention relates to a top closure for shaft furnaces, in particular Blast furnaces with a feed hopper opposite to which is a temporarily rotating one the stationary parts of sealed rotary funnels.
  • a bell-type top seal is in the upper area a "small bell” and in the lower area a “big one” Bell ".
  • the upper one of the bells arranged one above the other or funnel rotatable.
  • the invention is therefore based on the issue of a gout closure Kind without providing the disadvantages mentioned, while being structurally simpler and easier to assemble and easy to maintain.
  • a sealing unit consisting of from one arranged above the rotating funnel, to the funnel flange complementary, lifting and lowering adjustable flange, the has flange-side seals and in one with the adjustable flange the bridging wall connecting the stationary part of the rotating funnel a compensator element is formed.
  • the compensator element advantageous for example a loop-like band formation or the like, can be designed so that e.g. an axial movement of approx. 50 mm, a lateral one Movement of approx. 20 mm and an overpressure of 3.5 bar were recorded can be.
  • the system can be controlled so that during the material feed the adjustable flange from the receiving funnel into the "little bell" room is raised.
  • the rotating funnel can rotate for material distribution.
  • the adjustment flange is lowered, see above that the parts are sealed to one another, which allows a necessary one Perform pressure equalization.
  • the movement game that allows deformable compensator element is also capable of a possible Compensate for offset with respect to the axis of rotation.
  • the entire sealing unit or the sealing system is easily accessible from the outside and also enables installation on site.
  • a preferred embodiment of the invention are on the circumference of the stationary Part of the rotary hopper distributed and fixed there lifting cylinders connected to the adjustment flange. Take over these hydraulic cylinders not only lifting and lowering and thus lifting the adjustment flange during the material feed, but can simultaneously apply a holding force, which only needs to be large enough to lift the sealing unit is prevented due to the force from the internal pressure of the shaft furnace.
  • the adjustment flange carries two at a distance ring seals arranged from one another, of which the to the axis of rotation of the Rotating funnel adjacent, front ring seal than when the adjustable flange is raised a seal preventing dust leakage is formed.
  • the material feed is the one that is shifted towards the front of the adjustment flange, outer ring seal ineffective in the raised position of the adjustment flange, i.e. it is not in engagement.
  • the Front ring seal also in the lifted operating position of the adjustment flange a dust leak.
  • the cylinders are moved into the "large bell” room, so that a seal the parts to carry out the necessary pressure equalization.
  • the funnel flange is removed from the ring seal during the process of lowering increasingly approaching adjustment flange on the counter surface lying dust particles are gripped and displaced by the sealing edges of the ring seal, so that a quasi dust-free sealing surface is created.
  • One embodiment of the invention provides that between the rotating funnel flange and a stop is arranged on the adjustment flange.
  • This one preferred adjustable stop attached to the rotating funnel flange prevents inadmissible Pressing the seals. The adjustability allows one to compensate for possible seal wear.
  • the compensator element a sliding apron is connected upstream of the furnace or funnel interior, which is only fixed with one end to the bridging wall and with loosely abuts the other end of the bridging wall.
  • the compensator element there is a reinforcing apron in front of the print area, which due to their one-sided loose design when lifting the Adjustable flange slides with this free end over the bridging wall.
  • Fig. 1 of the overall symmetrical system arrangement as a symmetry half in very schematically, only one hopper 1 with one arranged below it Rotating funnel 2 ("Little bell”) shown, being between the rotating funnel 2 and the hopper 1 a stationary part 3 is provided.
  • the rotating funnel 2 are not shown drive means for rotation about the Assigned axis of rotation 4.
  • a sealing unit 5 is arranged in the space between the rotating funnel 2 and the stationary, load-bearing Part 3, a sealing unit 5 is arranged.
  • this includes one above the funnel flange 6 and to this complementary lifting and lowerable adjustable flange 7, the two on its underside concentrically at a distance from each other arranged ring seals 8, 9, of which the Rotary axis closer ring seal 8 as a dust seal with a rotating funnel flange 6 facing bristle 10 is formed.
  • Over the scope of the stationary part 3 of the rotary hopper 4 are distributed several lifting cylinders 11 attached and connected at its other end to the adjustment flange 7. on the other hand is in a connecting flange 7 with the stationary part 3 cylindrical jacket-shaped bridging wall 12 a loop-like Compensator element 13 formed.
  • FIG. 1 shows the operating phase before the discharge into the rotating funnel 12 abandoned material in which the lifting cylinder 11 lowered the adjustment flange 7 have that the parts are sealed to each other to a to be able to carry out the necessary pressure equalization.
  • the end position of the positioning movement is defined by an adjustable or interchangeable stop 16, which at the same time prevents inadmissible pressing of the ring seals 8 or 9.
  • the loop-like Compensator element 13 enables a compensation of the due to the Cylinder adjustments occurring movement play.
  • the compensator element 13 can do both an axial movement and a lateral movement balance and also absorb a certain excess pressure.
  • the rotary axis closer Ring seal 8, the bristles 10 also in the raised or ventilated state on the counter surface of the rotating funnel flange 6, prevents a rotation in this rotary operating phase of the funnel 2 Dust escaping.
