Definitions

  • the coking oven has an inlet through which material to be coked is to be admitted, and a supply arrangement is movable above the coking oven for supplying such material.
  • a filler pipe is downwardly extendable from the supply arrangement and has a lower end portion which can be placed into registry with the inlet.
  • a terminal section on the lower portion embraces the same and is sealingly connected therewith.
  • a lower end of the terminal section projects downwardly beyond the lower end portion of the filler pipe and is part-spherically shaped, and surrounded and in tilting engagement with an annular member which is connected with the terminal section by springs.
  • the annular member thus can be seated on the wall surrounding the inlet and, if either the pipe or the wall having the inlet should be inclined relative to one another, the annular member can accommodate itself to this inclination and reliably seal the inlet against the escape of emissions.
  • the present invention relates generally to ovens, and more particularly to coking ovens. Still more particularly the invention relates to an arrangement for preventing emission from coking ovens when the latter are being supplied with material.
  • Coking ovens have an upper wall provided with a number of inlets leading to the respective coking chambers.
  • Material to be coked that is coal
  • Material to be coked is admitted through these inlets from above, usually by means of carriages or similar supply devices which can move along and above .the wall having the inlet.
  • Two criteria are most important in the supply of such material, namely on the one hand that the coal be able to run freely out of the supply arrangement into the inlet, and on the other hand that the occurence of emissions (coal dust, gases or the like) be prevented as much as possible.
  • the present invention is particularly concerned with this latter aspect which requires, of course, that the inlet be closed tightly with respect to the ambient atmosphere during the filling operation.
  • an object of the invention to provide, in an oven, particularly a coking oven, a novel arrangement which avoids the possibility that emissions may occur during filling of material into the oven.
  • an oven especially a coking oven
  • a combination which comprises wall means having an inlet through which material is to be admitted into the oven, and supply means for supplying material to be so admitted.
  • a filler pipe has a lower end portion and is extendable downwardly from the supply means toward the inlet in substantial registry therewith when the supply means is located above the inlet.
  • a terminal section is provided on the lower end portion for tightly connecting the interior of the filler pipe with the inlet.
  • the terminal section comprises a tubular member coaxial with the lower end portion projecting from the same and having a part-spherical free lower end.
  • An annular member is located downwardly adjacent the free lower end and has a surface in mating engagement with the part-spherical free lower end so that the annular member is tiltable relative to the tubular member.
  • Spring means connects the annular member with the tubular member.
  • FIG. 1 is a fragmentary vertical section through an embodiment according to the present invention, on line A-A of FIG. 2;
  • FIG. 2 is a section taken on line B-B ofFlG. 1, looking in the direction of the arrows.
  • FIGS. 1 and 2 DESCRIPTION OF THE PREFERRED EMBODIMENTS Discussing the embodiment in FIGS. 1 and 2 in detail it will be seen that a supply unit has been illustrated only diagrammatically, being well known to those skilled in the art. Telescopically extendable in downward direction from the supply unit, in a manner well known to those skilled in the art, is a filler pipe I of which only the lower end portion has been illustrated. The upward and downward movement of the pipe I is designated by the double-headed arrow in FIG. 1.
  • An upper wall of a coking oven 0 has been fragmentarily and diagrammatically illustrated, being seen to be provided with an inlet I through which material (i.e. coal) is to be admitted into the oven. Usually, such ovens have four or five or perhaps even more such inlets in their upper wall, but one will suffice for purposes of illustration.
  • the lower end portion of the pipe 1 is embraced and externally surrounded by a terminal section having a tubular member 3.
  • a terminal section having a tubular member 3.
  • the present invention shows in the illustrated exemplary embodiment that it is possible to have only the terminal section, namely the tubular member 3 thereof, be raised and lowered as indicated by the double-headed arrow 1.
  • a packing 2 Located in the recess in the inner circumferential wall of the tubular member 3 is a packing 2, in form of annular sealing members which may, for instance, be of Teflon (TM), hard rubber, asbestos, graphite or graphite-asbestos rope, to mention only a few suitable materials.
  • a sleeve 3a is threaded onto the exterior of the filler pipe 1 and extends into this recess of thetubular member 3, serving to retain the packing material 2 therein.
  • the sleeve 3a may be connected with the tubular member 3 by means of bolts, rods or the like 3b having a sufficient length to permit the member 3 to perform upward and downward movements as shown by the arrow in FIG. 1.
  • the packing 2 reliably prevents the escape of emissions.
  • the lower free end of the tubular member 3 is of part-spherical configuration and is in contact with a similarly configurated surface of an annular member 6. They cooperate therefore in the manner of a ball-andsocket joint, meaning that the member 6 can swivel or tilt with respect to the member 3.
  • the member 6, whose interface with the member 3 is indicated by the arrow 5, is connected to the member 3 in such a manner as to permit the tilting to take place.
  • the member 3 is provided at circumferentially spaced locations (at three of them in the illustrated embodiment, as seen FIG. 2) with lugs 4a, 4b and 4c, respectively.
  • the member 6 in turn is provided with similarly circumferentially spaced lugs 4a", 4b" and 40', respectively.
  • contraction springs 4a, 4b and 40 each of which has its opposite ends connected to two cooperating lugs.
  • the spring 4b which is visible in FIG. 1 has its opposite ends connected to the lug 4b and the lug 4b", respectively.
  • the annular member 6 is retained on the member 3 but with sufficient freedom of tilting movement so as to accommodate itself to circumstances where either the pipe 1 or the wall having the inlet l might be inclined relative to one another, that is a situation in which the longitudinal axis of the pipe 1 might be skew with reference to the central axis of the inlet l.
  • annular member 6 can pivot or tilt relative to the tubular member 3 so as to be in proper surface-to-surface contact with the wall of the oven 0, whereby a proper tight emission-preventing engagement of the member 6 with this wall is assured.
  • the member 3 is additionally provided with two or more pins, projections or bolts 70, and appropriate manipulative devices of the supply unit (not illustrated, because they are known per se in the art) can engage these bolts 7a, 7b in order to raise or lower the terminal section 3 in accordance with the double-headed arrow shown in FIG. 1.
  • a combination comprising wall means having an inlet through which material is to be admitted into said oven; supply means for supplying material to be so admitted; a filler pipe having a lower end portion and extending downwardly from said supply means toward said inlet in substantial registry therewith when said supply means is located above said inlet; and a terminal section on said lower end portion for tightly connecting the interior of said filler pipe with said inlet, said terminal section comprising a tubular member coaxial with said lower end portion, projecting from and being surrounded by the same and having a part-spherical free lower end, sealing means between and in sealing engagement with said terminal section and said lower end portion; an annular member located downwardly adjacent the lower end and having a surface in mating engagement with said part-spherical free lower end so that said annular member is tiltable relative to said tubular member said lower end portion and said annular member being provided with respective angularly spaced connecting lugs; and spring means connecting said annular member with said tubular member, comprising
  • sealing means comprises sealing rings of sealing material.
  • sealing material is selected from a group composed of teflon (TM), hard rubber, asbestos, and graphite.
  • sealing material is graphite-asbestos cord.
