Definitions

  • ABSTRACT A charging car for coke ovens of the type in which coke is conveyed through feed pipes into holes extending through the tops of the ovens, characterized in that the covers can be removed from the holes, coal charged into the ovens and the covers replaced without permitting the escape of dust and smoke into the atmosphere.
  • gripping devices which are located in housings connected to the sides of sleeves which surround the feed pipes. These gripping devices are pivotal from vertical positions to horizontal positions to remove or replace charge hole covers which normally cover the charge holes extending through the tops of the ovens.
  • coal to be coked is discharged from a number of hoppers carried on a charging car into a corresponding number of holes or openings in the oven roof, from whence the coal falls down into the heated oven.
  • the charging car travels on rails mounted on the roofs of adjacent ovens such that it can travel from a storage area where coal is charged into the bins carried on the charging car to the desired set of holes or openings in the top of a selected oven.
  • the charging car is provided with as many hoppers as there are charging holes in the top of an oven chamber. These charging holes are sealed by covers which rest on metal charging hole frames so as to be gas-tight. The covers, of course, must be removed before charging and replaced after charging.
  • the hoppers on the charging car have outlets which empty into feed pipes; and the lower ends of these feed pipes are surrounded by sleeves which can be lowered to engage the periphery of the charging hole and thus prevent the escape of gases.
  • the present invention provides a means for charging coke ovens with a charging car of the type described above wherein the escape of gases and dust into the atmosphere is prevented. This is accomplished by providing sleeves around the bottoms of the aforesaid feed pipes which are lowered into abutting engagement with the peripheries of the feed pipes, and by providing lifting devices for the charge hole covers which are carried within enclosures communicating with and located at the sides of the sleeves so as not to interfere with the discharge of coal into the oven. Carried within the aforesaid enclosures are pivoted arms carrying gripping devices which are adapted to grip the charging hole covers and elevate them through an arcuate path of travel; whereupon the discharge of coal into the oven is permitted.
  • the charging hole cover is replaced by the aforesaid pivoted arm which is enclosed within the aforesaid enclosure and the sleeve then elevated.
  • removal of the charge hole cover is effected after the sleeve surrounds the periphery of the charging hole and is replaced prior to the time that the sleeve is removed from the periphery of the charging hole, thus preventing the escape of pollutants into the atmosphere.
  • FIG. I is an elevational view, partly in section, showing a coke oven charging car and its relationship to an individual charging hole in the top of a coke oven and a feed pipe set on the same;
  • FIG. 2 illustrates, on a larger scale, a vertical section taken substantially along line IIII of FIG. 1 through the feed pipe of the coke charging car;
  • FIG. 3 shows, on still a larger scale as a detail from FIG. 1, the lower part of the sleeve carried on the feed pipe, which can be raised and lowered as well as the housing for receiving the raised charging hole cover.
  • each oven chamber has several charging holes 3 which are located one behind the other along the longitudinal width of the oven.
  • FIG. I which represents a section in the longitudinal direction of the coke oven battery, only one of the charging holes is shown.
  • the charging car shown in FIG. 1 is provided with wheeled trucks 25 and 26 which roll on rails 27 laid on the oven roof I.
  • a number of hoppers 39 is carried on the charging car corresponding to the number of charging holes for each oven.
  • These hoppers 39 are provided with an outlet from which the coal is conveyed to a feed pipe 2 by a turntable device more fully described in copending application Ser. No. 61,166, filed concurrently herewith.
  • the feed pipe 2 can be raised or lowered and is provided at its lower edge with an annular flange 10. This flange, when the feed pipe 2 is lowered, rests on a charging hole frame 8 which surrounds the charging hole 3 and is provided with a beveled surface 7 which supports a charging hole cover 5.
  • the charging hole cover 5 is shown in its position removed from the charging hole 3. In FIG. 3 it is shown covering the charging hole by broken lines and is identified by the reference numeral 50. The position occupied by the flange 10 when the feed pipe 2 is retracted is identified in FIG. 3 by the reference numeral 100.
  • a wall 38 forms with the feed pipe 2 an enclosure 15.
  • Carried within the enclosure 15 is a mechanism comprising two arms 11 and 14 secured to an axle l3 and rotatable as a unit about that axle.
  • the axle extends through the enclosure 15, is connected to the arm 11 within the enclosure, but extends through the side of the enclosure and is connected to arm 14 outside the enclosure.
  • the arm 14, in turn, is connected through linkage 19 to a lever 16 pivotal about a fixed axis 17.
  • the upper end of the lever 16, in turn, is pivotally connected at 21 to the piston rod 22 of a hydraulic or pneumatic cylinder 23.
  • the gripping device 4 is preferably an electromagnet; while the charge hole cover 5 is formed from a magnetically permeable material such that the gripping device 4 can be lowered into engagement with the charge hole cover 5, the electromagnet energized and the arm 11 and the gripping device 4 rotated in a clockwise direction as viewed in FIG. 3 to lift the cover 5 off its seat 7.
  • a discharge funnel 6 Carried within the feed pipe 2 is a discharge funnel 6 which is basically in the shape of a cylinder. However, it is flared out wardly at its top and is provided with an annular seal 12 which rides on the inner periphery of the feed pipe 2. In the lowered position, the discharge funnel 6 rests with its lower edge 24 on the beveled surface 7 of the charging hole frame 8.
  • the discharge funnel 6 is raised or lowered by a mechanism including guide chambers 28 and 29 (FIG. 2) which are located opposite each other on either side of the feed pipe 2. Extending downwardly into the chambers 28 and 29 are rods 30 which are, in turn, engaged by friction drive wheels 31 connected to suitable drive motor means, not shown. In this manner, rotation of the guide wheels 31 in one direction will cause the rods 30 to move upwardly; while rotation of the wheels 31 in the opposite direction will cause the rods 30 to move downwardly.
  • the rods 30, at their lower ends, are connected to arms 32 mounted on the walls of the funnel 6 such that movement of the rods upwardly or downwardly will also cause the funnel 6 to move upwardly or downwardly.
  • the arms 32 slide within slots 33 (FIG.
  • the charging car is positioned above a charge hole 3; and the feed pipe 2 initially lowered by means, not shown, such that its lower flange 10 rests on the charging hole frame 8.
  • the discharge funnel 6 is still in its upper position.
  • the arm 11 is caused to rotate in a counterclockwise direction such that the gripping device 4 engages the charge hole cover 5.
  • the electromagnet is then energized and the cylinder 23 reversed; whereupon the arm 11, gripping device 4 and the charge hole cover 5 are moved to the full-line position shown in FIG. 3 where they are within the enclosure 15.
  • the discharge funnel 6 is then lowered and coal is charged into the oven through the charging hole 3.
  • suction devices for the charging gases can also be placed on the charging car itself. These may comprise, for example, an elbow 34 (FlG. 1) connected at one end to a suction pipe 35 and at its other end to each of the feed pipes 2. One or several such suction pipes 35 direct the waste gases to a blower 36. From here, the gases are discharged to the atmosphere through a filter 37.
  • said linkage means includes an arm pivotally connected at its one end and carrying at its other end said gripping element, and linkages connecting said arm to a prime mover for rotating said arm about its pivotal connection at said one end through said arcuate path.
  • said gripping element comprises an electromagnet and said charge hole cover is formed from magnetically permeable material.
