  • This invention relates to apparatus for charging coke ovens' by means of a charging car, in which the charge passes directly from at least one hopper to the charging hole without the need for any handling equipment between the hopper itself and the obturatable members feeding the charge and guiding it into said hole.
  • the apparatus according to the invention is also intended to provide a remedy for atmospheric pollution caused by smoke emission when charging.
  • the invention accordingly provides for apparatus comprising a hopper within which is mounted, beneath a protector, a slidable obturator adapted to seal off the lower part of said hopper by covering the inlet orifice of a raisable telescopic distributor which is in turn adapted to penetrate into a charging hole or to be retracted beneath said obturator.
  • the telescopic distributor cooperates with a likewise raisable smoke box which, in its lowermost position, is adapted to be applied against the periphery of the charging hole into which said telescopic distributor penetrates with suitable clearance.
  • the protector, the obturator and the telescopic distributor are made of tubular elements.
  • the obturator thus slides within the protector while the distributor tube slides in similar manner within the obturator.
  • the protector itself is provided with acontoured head and with suitably distributed attachments for preventing arching in the hopper charge.
  • control means may comprise a rod extending through the top of the protecting tube via a sealing gland and connected by a cable or the like to the piston of a compressed air actuator which may be of the single-acting type.
  • Ancillary equipment such as vibrator and an indicator device of the end of charging may be associated to such an arrangement whereby to facilitate the flow of the charge and the return of the obturator to its lowermost position.
  • the hopper is contoured symmetrically, but the apparatus of the present invention may also be utilized with an asymmetrically contoured hopper.
  • the protector attachments are accordingly positioned on a counterslope while the said vibrator and indicator are positioned on a sloping face.
  • said indicator prefferably be positioned on the corresponding wall at a height such that a residual charge remain in the hopper permanently and thereby perform the sealing function on completion of the charge dumping operation.
  • Controls are also provided for raising the telescopic distributor and the smoke box through a distance -such that an ample gap be provided for convenient access to the charging hole obturating plugwhen the hopper overhangs the hole, said plug being operable by mechanical Withdrawing and replacing means rigid with the hopper wagon.
  • FIGURE 1 shows in diagrammatic section a coke oven charging apparatus in the charge dumping position
  • FIGURE 2 shows in corresponding manner the apparatus in the position for interrupting the dumping process
  • FIGURE 3 is a detail view of the emergency control means.
  • the construction-a1 form shown for illustrative purposes relates to the more complex general arrangement of an asymmetrically contoured hopper, but it will be obvious that the apparatus according to the invention could consist of similar components in the case of a symmetrical hopper.
  • the apparatus shown in the drawings comprises a hopper 1 of which one wall 2 has a slight reverse slope and the opposite wall 3 a steep slope. Above these walls, the hopper 1 comprises a cylindrical rim 4 at the top of which is provided a cross-member 5 adjacent the extension of wall 2.
  • the base of the hopper is joined to a frusto-conical termination 6 the smaller base of which has formed thereon a seat 7 against the inside of which the terminal flared portion 8 of a tubular telescopic distributor 9 is adapted to bear leak tightly.
  • Said distributor is retractable into the termination 6 and the hopper 1, and its movement is guided by uniformly distributed fixed external guides 16 rigid with the outer surface of the termination and against which slides the cylindrical outer surface of the distributor 9.
  • a cylindrical protector 13 Secured to said hopper through the medium of brackets 11 and 12 rigidly united with the inner surface of the wall 2 is a cylindrical protector 13 whose top is rigid with a conical cap 14 and Whose base is left open. At the top of the cap 14 is a sealing gland 15 through which is slidable a rod or tube 16. Within the protector and its cap, the rod 16 is rigidly connected to a tubular obturator 17 Whose bottom is provided with a flared bearing lip 18 adapted to sealingly cooperate with the internal conical surface of the termination 6 when the obturator 17 is lowered, said lip not projecting to a substantial degree from the base of the protector 13 when the obturator 17 is raised into the protector.
  • the upper end of rod 16 is attached to a cable 19 which runs over an intermediate pulley whose supporting shell is mounted on the cross-member 5, and thence over a further intermediate pulley 21 whose shell is fixed to the outside of the rim wall 4.
  • This cable is attached through an abutment-piece 22 to the end of the rod 23 of the piston 24 of an actuator whose cylinder 25 is pivotally connected, through a lug 26 on its end closure, to a yoke 27 secured to the outside of wall 2 at the appropriate height, the pivotal connection being provided by a pin extending through said yoke and said lug.
  • said cylinder Adjacent its lower end closure, said cylinder is provided with a vent 28, while the upper end closure 29 is connected to a feed pipe 30 and also forms a fluid-tight guideway through which the rod 23 extends.
  • the pipe 30 is connected to a compressed air source 31 through a three-way manually operated cock 32 which permits feeding the cylinder 25 or decompression thereof.
  • the cock 32 can be by-passed through a pipe branch 33 into which are inserted two shut-off valves 34 and 35 positioned on either side of an electrovalve 36 whose electric circuit is connected to a switch 37.
  • the switch 37 is actuated through a rod 38 connected to an arm 39 carrying a counterweight 40, and this arm is pivotable about a hinge 41 inset into the thickness of the wall 3, the entire arrangement being so devised that said hinge be leaktight and that the arm 39 be rigid with a downwardly directed flap 42 adapted to be flattened by the charge in the hopper 1 against the wall 3 when the counterweight is raised and to be restrained in that position by the charge, and furthermore that the flap 42 be lifted once more by the downward movement of the counterweight 40 after the charge has passed below the level of said flap.
  • the function of these horizontal portions 50 is to raise the smoke box 49 by abutment against the upper end closure thereof.
  • the smoke box itself constitutes a kind of bell equipped with at least one lateral stub-pipe 51 intended for connection to a smoke extraction device (not shown).
  • the bell skirt Near its bottom the bell skirt comprises a flange 52 which, in the lowered position, is adapted to bear against the rim 53 of a charging hole 54 formed in the paving 55 constituting the roof of a coke oven, the size of the hole 54 being such as to enable the tube 9 to be insertable thereinto with suitable clearance.
  • FIGURE 3 clearly shows, to the cross-member 5 is rigidly connected a bracket 56a on top of which is fixed a sleeve 56.
  • This sleeve receives therein a threaded rod 57 provided with a hook 58 adapted to cooperate with a gusset 59 carried on the top of the rod 16.
  • Onto said threaded rod screws a handwheel 60 whose hub bears against the end face of the sleeve 56.
  • This handwheel and threaded rod constitute emergency manual actuation means of the obturator 17.
  • FIGURE 1 shows that the obturator 17 can be lifted without ditficulty into the protector 13 without encountering opposition from the charge contained in the hopper l, the only restraint exercised being due to friction against the vertical wall of the obturator and to the resistance offered by the flared end 18.
  • the lifting operation is effected by the actuator 25.
  • the distributor 9 is inserted into the charging hole 54 to the required depth, thus ensuring that the flow is correctly directed into the chamber without any of the mixture being lost or scattered over the paving 55, by reason of the seal obtained by cooperation of the flared part 8 with the seat 7.
  • the smoke box 49 is then lowered and the smoke rising from the hole 54 around the tube 9 is thus collected and discharged through the extraction pipe 51.
  • the catch 43 operates the switch 45, which in turn renders the vibrator 46 operative for a preset time, thus preventing the charge from being restrained by the wall 3 and also making the flow rate more rapid and uniform.
  • the downward swing of counterweight 40 actuates the switch 37 which in turn activates the electrovalve 35 which moves to the venting position on the side of the cock 35 and shuts off the air intake on the side of the cock 34.
  • the obturator 17 then moves down under gravity, being assisted in this movement by the continuing flow of the charge.
  • the obturator 17 drops until the flared portion 18 contacts the inner surface of the termination 6. The flow is then interrupted and tightness maintained throughout the operation by the charge itself and by the residual quantity thereof above the portion 18.
  • the entirety of the charge below the portion 13 is then discharged, thereby freeing the space through which the distributor 9 can then be raised to penetrate into the obturator 17.
  • the rising motion of the distributor 9 in response to the arms 47 ultimately causes the box 49 to be raised also.
  • the charging hole 54 is then cleared and an obturating plug can be replaced thereon without difliculty.
  • FIGURE 2 Reference to the situation of the various components in FIGURE 2 shows that the hopper 1 is ready for refilling.
  • the hopper can then be moved into position above another charging hole, from which the plug can be removed for insertion of the distributor 9.
  • the smoke box covers the hole and charging can take place as soon as the obturator has been raised to enable the operations hereinbefore described to be effected anew.
  • the presence of the protector makes only a very small force necessary to move the obturator. Moreover, the shape of the protector and its attachments prevents snagging and humping.
  • the rising motion of the obturator rapidly decompresses the charge and facilitates and speeds up the flow.
  • a coke oven chamber charging apparatus having at least one hopper having distributing means of its coal charge, said hopper being movably mounted over juxtaposed chambers on the upper paving of said coke oven, whereby successively charging said chambers when at least a charging hole is aligned with said distributing means, wherein are present in combination, a hopper, an internally disposed tubular protector inside said hopper, a tubular obturator slidably mounted within said protector, obturator having a lip, a guide at the base of said hopper, said guide being inside the contact line of said lip on said base when said obturator is in obturating position, a slidable telescopic tubular distributor in said guide, adapted for penetrating a charging hole when lowered and for being retracted inside said obturator when raised, means for moving said obturator, and means for moving said telescopic distributor.
  • a raisable smoke box which, in its lowermost position is adapted to be applied against the periphery of a charging hole into which said telescopic distributor penetrates with play, said smoke box being slidably mounted on said telescopic distributor and having moving means for its raising and lowering.
