Definitions

  • the invention relates to a locking device for the overvoltage of a pipeline compensator, two straps being attached to one side of the compensator overvoltage, which transmit the transverse forces via a cross bolt and a sliding block to a strap fastened to the opposite side.
  • Compensator overvoltages of this type are provided for the movement compensation of hot pipelines of shaft furnaces, in particular in the case of blast furnaces, for example in the blast furnace gas pipeline system.
  • Such compensators with overvoltage can be used according to DE-36 41 138 C1, because due to considerable temperature differences between the furnace frame and the hot wind ring line strains or thermal stresses occur there.
  • the known compensators with corresponding overvoltages are said to allow angular movements and axial displacements of the nozzle assemblies.
  • the object of the invention is to achieve the shortest downtimes when changing the nozzle and to fix the compensator in position when changing the individual parts of the nozzle assembly, so that the weight of the parts still hanging on the compensator - intermediate tube or intermediate tube with nozzle manifold bend - can be absorbed.
  • the device according to the invention for locking the compensator and the compensator overvoltage can consist, for example, of two flat bars which have a recess on the loose side and which are connected to a compensator flange so as to be rigid in relation to the compensator overvoltage by 90 °.
  • Threaded bolts are attached to the other flange of the compensator, which are inserted into recesses on the flat bars.
  • the recesses on the flat bars must be large enough so as not to hinder relative movements between the flat bars and the threaded rods.
  • the locking is actuated in such a way that nuts on the and the compensator and the compensator overvoltage are fixed between two flanges by tightening with lock nuts.
  • the locking device After completing the repair work and before starting up the nozzle assembly, the locking device is relieved by loosening the two nuts on the threaded rods and taken out of operation.
  • the flat bars can be locked with the compensator flange with the aid of a transportable assembly pressure cylinder.
  • Fig. 1 shows the section of a nozzle assembly with the compensator and the locking device according to the invention in cooperation with the compensator overvoltage.
  • Fig. 2 shows the side view of the compensator.
  • Fig. 3 shows a half section through the locking device which is fixed with the aid of an assembly pressure cylinder.
  • Fig. 4 shows the hydraulic pressure cylinder in a vertical section.
  • FIG. 1 and 2 show the nozzle assembly of a blast furnace, which is equipped with a multi-wall compensator (1) to absorb thermal expansion and relative movements between the blast furnace and the nozzle of the hot wind ring line (13).
  • the compensator (1) is used to transmit transverse forces, which largely consist of the internal pressure and the weight of the nozzle tip (3), elbow (4), the intermediate pipe section (5) and the refractory lining (14), with a compensator overvoltage (2) provided, which prevents lateral movements in the nozzle block level, but allows all other movements.
  • the compensator (1) In order to achieve short change times, the compensator (1) must be fixed in position during the change of the nozzle tip (3), the locking device having to bear the weight of the intermediate pipe (5) including the refractory material (14).
  • the lock consists of two flat bars (6), which are connected to the upper compensator flange (7) so that they are stiff against bending in relation to the overvoltage (2).
  • Threaded bolts (9) are attached to the lower compensator flange (8) and extend through a recess (12) into the flat bars (6).
  • nuts (10) and lock nuts (11) are screwed onto the threaded bolts (9) and the flange (8) is frictionally pressed against the flat bars (6) by tightening the lock nut (11).
  • 3 and 4 show a further embodiment of the locking device, which is carried out instead of the previously described fixing of the flat bars (6) on the compensator flange (8) with the aid of an assembly pressure cylinder (17).
  • a pressure cylinder (17) is inserted into the respective recess (15) of the compensator flange (8) and initially held in suspension by a holder (18). With the help of a hydraulic pump (19), the hydraulic cylinder (17) is pressed against the flat bar (6) via a casing plate (16). The locking device is thereby able to fix the compensator (1) in position during the replacement of the wear parts (3, 4) described above.
