Definitions

  • the invention relates to a device for cleaning the sealing surfaces of the bulldozer frame on the doors of horizontal chamber coking ovens, in which a mechanically operated cleaning tool can be pushed against the sealing surface of the bulldozer frame to be cleaned after opening the bulldozer door in question.
  • Such a cleaning device is known from DE-OS 29 14 419. Although this device works quite satisfactorily, it is perceived as a disadvantage that, when it is arranged on the coke extraction machine, it has to move to an additional working position for this.
  • the invention is therefore based on the object of designing the cleaning device of the generic type in such a way that the sealing surface can be cleaned in the leveling position, i.e. there is no need for a process of the coke extrusion machine between the cleaning and the leveling process.
  • the aim is to simplify the design of the cleaning device.
  • the invention proposes a device which is characterized in that the cleaning tool consisting of a single knife, scraper or the like is connected to a carriage, the rollers of which are guided in rails, the rails at the end of the furnace the bulldozer stored coke lock attached and movable together with this in the working position, and that the car with a Actuator is connected, the way to work is such that the cleaning tool covers the entire sealing surface of the bulldozer frame and releases the bulldozer opening before and after the cleaning process.
  • the device according to the invention makes it possible to clean the sealing surface of the leveling hole frame in the leveling position of the coke pressing machine, i.e. it is unnecessary to move to an additional position for the cleaning process with the coke-pressing machine, as is essential in the known cleaning device.
  • the connection of the proposed cleaning device to the leveling lock also makes it possible to dispense with a special drive for the positioning of the cleaning tool; rather, this inevitably takes place together with the positioning of the leveling lock.
  • the invention further provides that the cleaning tool is resiliently mounted on the carriage performing the cleaning movement. This enables differences in position of the leveling frame to be easily compensated for.
  • a hydraulic cylinder is preferably provided as the actuating device for the carriage, the stroke of which can be transmitted to the carriage via angle levers and handlebars.
  • the invention also proposes that the working path of the actuating device and thus that of the cleaning tool can be adjusted by means of lining plates.
  • Fig. 1 denotes the coke oven door shown in section, in the upper region of which the leveling opening 2 is arranged. This can be closed by means of the leveling door 3, which is shown in the drawing in the open position.
  • the door opening device provided for this purpose is indicated by 4, with the aid of which in the present case the leveling door is pivoted upward during the opening process.
  • 5 is the bulldozer frame with the sealing surface 6.
  • the coke pushing machine In front of the coke oven door 1 or the oven chamber closed by this, the coke pushing machine has moved into position, of which only parts indicated by 7 are shown in FIG. 1.
  • the dozer 8 is displaceably mounted on the axis of the dozer opening 2 on the coke pressing machine. Through the leveling lock and the leveling opening, the leveling rod, not shown here, is inserted into the furnace chamber for the leveling process.
  • the cleaning device according to the invention for the sealing surface 6 of the bulldozer frame is attached to the end of the bulldozer 8 facing the kiln door or the kiln chamber.
  • This has pairs of rails 9 arranged on both sides of the leveling lock 8 in accordance with the inclination of the sealing surface.
  • the rollers 1o of a carriage 11 are guided in the two pairs of rails, who carries the cleaning tool designed as a knife 12.
  • the cleaning tool is connected to the carriage via pressure bolts 13 and compression springs 14, so that it rests against the sealing surface 6 in the illustrated working position.
  • the carriage 11 is driven by a hydraulic cylinder 15 which is articulated at 16 on the leveling lock 8.
  • the stroke of the piston of the hydraulic cylinder is transmitted to the carriage 11 via a cross member 17, connected to it and on both sides of the leveling lock at 18, the angled lever 19 and link 2o.
  • the stroke of the piston is dimensioned such that the cleaning tool 12 connected to the carriage 11 sweeps the entire sealing surface 6 and cleans it of adhering condensates.
  • the upper and lower end position of the carriage 11 is shown in Fig. 1 with solid or dash-dotted lines. Both end positions can be varied by lining plates 21 and 22 which can be attached to a stop 23 on the one hand and to the bearing 16 on the other hand.
  • On the angle levers 19 stops 24 and 25 are also arranged, which cooperate with limit switches 26 and 27. Time relays not shown here and operated by the limit switches cause the two end positions to be reached exactly.
