Claims
- 1. For metallurgical apparatus including a vessel, trunnion ring means supporting said vessel and trunnion pin means extending from said ring means to enable tilting of said vessel, at least one of said trunnion pin means having an axial bore, improved means for communicating fluids with said apparatus, comprising:
- a. adapter means in said axial bore of said pin means, said adapter means having a first bore that is generally axial of said adapter means and of said pin means and also having an first generally radial bore communicating with said axial bore, and said radial bore also being in substantial registry with a generally radial hole in said pin means,
- b. a first tubular element extending into said axial bore of said pin means and terminating in registry with and sealably with the axial bore of said adapter means, said first tubular element being rotatable with said adapter means and with said trunnion pin means when said vessel is tilted,
- c. said radial hole in said pin means enabling a continuous fluid flow path through said radial hole, said adapter means and said first tubular means,
- d. tubular sheath means for protecting said first tubular element against erosion, said tubular sheath means surrounding said first tubular element and being sealingly joined with said adapter means so as to close the end of the space between said inner first tubular means and said tubular sheath means,
- e. the outside of said tubular sheath means defining with the inside of said trunnion pin axial bore a passageway for selectively transporting fluids such as gas, gas which entrains finely divided materials and coolant,
- f. said trunnion pin means having a hole leading generally radially from said passageway to provide a path for conducting fluid through said pin means to or from said apparatus.
- 2. Metallurgical apparatus including a vessel, trunnion pin means supporting said vessel to enable tilting of said vessel, one of said trunnion pin means having an axial bore, improved means for communicating fluids with said apparatus, comprising:
- first and second radial openings in said trunnion pin means and communicating with said bore,
- adapter means disposed in said axial bore of said trunnion pin means, said adapter means having a first bore that is generally axial of said adapter means and of said pin means and a first generally radial bore communicating with said axial bore, and said first radial bore also being in substantial registry with said first radial opening in said trunnion pin means,
- a first tubular element extending into said axial bore of said pin means and terminating in registry with and sealably with the first axial bore of said adapter means and communicating with the first radial hole in said pin means to define a first continuous fluid flow path through said first radial hole, said adapter means and said first tubular means,
- said adapter means having a second generally axial bore concentric with and axially of said first axial bore,
- a second tubular element spaced from and surrounding said first tubular element and terminating in registry with and sealably with said second axial bore, said adapter means also having a second radial bore in substantial registry with a second generally radial opening in said pin means, said second radial bore communicating with a space defined by said second axial bore and said first tubular element which extends therethrough to define a second continuous flow path through said second radial opening, said adapter means and said second tubular means, said second tubular element being smaller than and spaced from the axial bore in said trunnion pin means to define a gap therebetween, a third radial opening is formed in said trunnion pin means and communicating with said gap to define a third continuous flow path,
- first pipe means coupled to one of the radial openings in said trunnion pin means and to said vessel for defining a gas flow path,
- said trunnion ring means having a passageway for conducting coolant fluid therein,
- second and third pipe means each respectively connected with said one of the other two radial openings in said trunnion pin means to the passageway in said trunnion ring means to provide a pair of coolant fluid paths between said trunnion ring passageway and two of said flow paths,
- said vessel having a pair of trunnion pins, said first named axial bore being formed in one of said trunnion pins,
- a second axial bore formed in the second one of said trunnion pins,
- a second adapter means in said second axial bore and having an axially spaced apart cavity,
- a third tubular member coupled in sealing engagement with the axial cavity of said second adapter means, said third tubular member being spaced from the axial bore in said second trunnion pin,
- tubular sheath means for protecting said third tubular element against erosion, said tubular sheath means surrounding said third tubular element and being sealingly joined with said second adapter means so as to close the end of the space between said third tubular means and said tubular sheath means, the outside of said tubular sheath means defining with the inside of said second trunnion pin axial bore a passageway for selectively transporting fluids such as gas which entrain finely divided materials,
- said second trunnion pin having a hole leading generally radially from said passageway to provide a path for conducting fluid through said pin means or from said apparatus.
