Definitions

  • the present invention is directed to a sealed coal-feeding system for use with a mechanical, turntable type larry car.
  • Apparatus for controlling the flow of gas into and from a coke oven chamber before and after charging with coal includes a fixed conduit mounted to the larry car and adapted for receiving coal when discharged by a turntable.
  • a flow control valve is mounted in the fixed conduit and is opened and closed in response to a pivotable shoe that engages the coal being discharged from the turntable.
  • a movable coal conduit telescopes with the fixed conduit and seals with the coke oven coal-charging hole.
  • FIG. 1 is a schematic elevational sectional view of a sealed coal-feeding system for a coke oven in accordance with the invention
  • FIG. 2 is an enlarged view of a detail of the structure of FIG. 1;
  • FIG. 3 is a sectional view along line III--III of FIG. 2.
  • FIG. 1 illustrates the lower portion of a mechanical-feed type larry car coal hopper 11 that is provided with a conventional internal cutoff gate 13, a rotatable turntable 15 and afixed coal conduit 17 that is provided with a cleanout cover or lid 19.
  • the fixed coal conduit 17 cooperates with a telescoping coal conduit 21 that is vertically reciprocable into and out of engagement, at its lower specially shaped end 23, with the periphery of a coal charging hole 25 ofa coke oven battery 27.
  • the telescoping coal conduit 21 is actuated by a cylinderpiston assembly 29 that is mounted suitably to the fixed coal conduit 17 and that is connected, as at 31, to the telescoping coal conduit 21.
  • a flow-regulating device 33 which may be the butterfly type of valve shown, or any other suitable device.
  • the control device 33 is actuated by mechanism 35 that acts in response to a signal from a sledtype pivotable shoe 37 located within the coal hopper 11 and above the turntable 15.
  • the telescoping coal conduit 21 is provided with a sealing device 39 comprised of wedge-sealing ring 41 and two superimposed layers of tangential segmental rings 43, 45.
  • the wedge sealing 41 has an arcuate convex surface 47 that is, preferably, spherical in shape so that it coacts with a conical surface portion 49 of the flared upper end portion SI of the telescoping coal conduit 21.
  • the flared upper end portion 51 is provided with a plurality of studs 53 that cooperate with an annular retainer ring 55 coacting with the tangential segmental rings 43, 45 to hold them in position; the retainer ring 55 coacting with springs 57 and nuts 59 on the studs 53.
  • Each segmental ring 43, 45 is comprised of a plurality of segments, such as 45a, 45b shown in FIG. 3, and adjacent segments 45a, 45b abut along a surface 61 that is generally biased toward the inner periphery of the segments 45a, 45b.
  • the surface 61 merges with a notch 63 which is provided in each segment 45a, 45b to allow for freedom of movement as the segments 45a, 45b wear in service.
  • Each of the segments 45a and 45b has a hole 65 therein that receives a dowel pin 67 secured as by threading into the segment 43a, 4312 located below the segments 45a, 45b.
  • the tangential segmental rings 43, 45 each have a groove in their outer peripheral surface in which a conventional gartertype spring 69 is cooperative to hold the several segments 45a, 45b, etc., and 43a, 43b, etc., against the outer surface of the fixed coal conduit 117.
  • the charging hole is prepared in the usual way, by removing the lid, and the telescoping coal conduit 21 is lowered so that the shaped lower end 23 flts cooperatively into the charging hole as shown.
  • the butterfly valve 33 is in the closed position (in FIG. l, the valve is open) and the turntable I5 is stationary.
  • the turntable I5 When it is desired to charge coal into the coke oven chamber 25, the turntable I5 is activated by a mechanism 71 of conventional characteristics located below the turntable and driven by a powered shaft 73. Coal 15 in the hopper II is slung outwardly below the gate 13 and the coal on the turntable raises the sled-type shoe 37. When the shoe raises, about its pivot 77, it activates a switch 79 that sends a signal to the mechanism 35. This mechanism 35 then rotates the butterfly valve 33 to the open position as shown.
  • the lower telescoping coal conduit is raised by actuating the cylinder-piston and the larry car moves to the next coke oven to be charged.
  • the mechanism seals the coke oven chamber and effectively prevents air from entering the chamber if it is under a negative pressure, or it prevents gases from escaping to atmosphere if the oven chamber is under positive pressure;
  • a movable coal conduit surrounding and telescopable with a portion of said fixed coal conduit, said movable coal conduit having an end adapted to coact with and seal against said coke oven chamber;
  • said means coacting with the coal on said turntable is a pivotable shoe; and including b. means operating in response to the movement of said shoe for opening and closing said coal flow control device.
  • said coal flow control device includes a butterfly valve pivotable in said coal conduit; and including b. means for opening and closing said butterfly valve.
