Definitions

  • a coal charging larry car is provided with a combina- [51] I111. Cl. F23k 3/00 don lid lifting and drop sleeve apparatus that provides [58] Fleld of Search" 101 101 10] a gas-flow passageway from an oven to be charged with coal to another oven twice removed in which coal is coking.
  • a reversible screw conveyor feeds coal into either oven as preferred.
  • the invention comprises a plurality of lid lifting devices mounted to a iarry car in such a way that lids on one oven and on another oven twice removed from the one oven being charged are removable.
  • Reversible screw conveyor means is provided to charge coal into the one oven and effluent gases that cannot escape through the ascension pipe of the oven being charged flow through the tubular element surrounding the screw conveyor into the other oven. These gases then flow through the ascension pipe into the collector main in the usual manner.
  • An inert gas purge system is provided to clean the apparatus of effluent gases that may remain therein after charging.
  • FIG. 1 is an elevational view of a coke oven battery looking at a section transversely thereof and showing apparatus in accordance with the invention
  • FIG. 2 is a view along line II-II of FIG. 1.
  • the tubular element 19 is cylindrical and within it there is located a screw flight 21 that has a shaft 22 that is journaled in a bearing 23 mounted at one end to a closure plate 25, and in a bearing 27 mounted at the other end to a closure plate 29; the shaft of the screw flight 21 extends beyond the bearing 27 and connects to a speed reducer 31 driven by an electric motor 33.
  • the motor 33 is a conventional reversible electric mtor.
  • the tubular element 19, it will be noted, is larger in diameter than the screw flight 21.
  • the tubular element 19 is provided, at a location about mid-way of its length, with a flanged opening 35 to which is mounted a flanged coal hopper 37.
  • a sliding gate valve or a butterfly valve or any other type of flow regulating device At the bottom of the coal hopper there may be installed a sliding gate valve or a butterfly valve or any other type of flow regulating device.
  • the top of the hopper 37 is provided with a removable lid 39 which is adapted to be made gas-tight and yet readily removable to pass coal into the 'hopper 37 to fill the same.
  • the larry or coal charging car is positioned over the oven 5 to be charged; a drop sleeve 47, as described in the aforementioned patent, is lowered to a position, as shown in FIG. 2, over a lid 49 (shown therein in the raised position).
  • the steam purge lines are filled with steam by opening valve 51 to fill the void spaces in the hopper 37 and in the top void portion of the tubular element 19.
  • the vertical lid lifter portion 53 of the apparatus 11 is then activated to engage the lid 49 and to raise it to the position shown in FIG. 2.
  • similar lid lifting apparatus llfi- is activated to raise the lid from oven 55 twice removed or' spaced two ovens away from oven 45.
  • intermediary oven 57 coal is being coked in a normal manner.
  • oven 45 has four charging holes numbered (though not shown) A, B, C, and D, in the top of the battery.
  • the lids on charging holes A, B, C, and D or oven 45 and the same lids on oven 55 are removed.
  • Such lids may, of course, be removed with the apparatus 11, 13 suggested in FIG. 1 or they may be removed by aconventional other means such as a magnetic lid lifter.
  • the steam purge system is activated to urge the fiow of heat and gases toward the collecting main.
  • Coal is charged then from hoppers B and I) into oven 45. Gases which evolve from the oven as the coal contacts the hot walls flow through the usual ascension pipe into the collecting main. After a short period of time which may be as long as 10 to 15 seconds, coal is charged from hoppers A and C into oven 45, and the oven is filled with coal.
  • oven 45 After oven 45 is charged and leveled in the usual manner, the steam purge will have cleared the hoppers and screw conveyors of any smoke and fumes. 1T hereafter, the lids on both oven 45 and 55 can be replaced.
  • the-coal in hopper 3'7 and the tubular member 19 may be charged either into oven 45 or into oven 55, as the case may be.
  • That the steam purge system helps to cool the gas that flows in the tubular member.
  • a. reversible means connected to each hopper for feeding coal from said hopper into either one chamber of two chambers of said battery and for carrying gases from said one chamber into the other chamber which is at least twice removed from said one chamber.
  • said reversible means is a tubular member in which there is a reversible screw conveyor.
  • a. a fluid purge system that is adapted to introduce an inert. gaseous fluid into the tubular member for removing effluent gases therefrom.
  • a tubular member mounted to each hopper, such member having therein a reversible screw conveyor;
  • a fluid purge system fitted to and adapted for introducing inert gaseous fluid into the oven being charged and into the tubular member.
