Definitions

  • EP 1 293 552 B1 A device with the described features is made EP 1 293 552 B1 known.
  • the horizontal screw conveyor and the filling telescope of the known device are combined to form an operating unit which is arranged in two axes adjustable on the underside of a coal filling carriage.
  • the horizontal screw conveyor is suspended on a Verstellwagen, which is guided on a roadway at the bottom of the coal filling car.
  • the horizontal screw conveyor is movable transversely to this web direction on profiles of the adjusting.
  • the problem is the transition between the coal outlet of the coal hopper and a hopper of horizontal auger. To avoid emissions, this transitional area must be sealed.
  • a compensator is used, which must compensate for lateral adjustment movements of the operating unit in two axes.
  • the coal outlet of the filling carriage has a large outlet cross-section, so that a compensator with large dimensions must be used.
  • the compensator is subjected to heavy stress.
  • Another serious disadvantage of the known device is that the known arrangement requires a large ground clearance between the coal outlet at the bottom of the coal filling carriage and the furnace roof of the coke oven. This is not always available.
  • the movable in two axes suspension of the horizontal screw conveyor is also structurally complex. For retrofitting existing coke oven plants, the known device is not suitable or only with restrictions.
  • the invention has for its object to provide a device for emission-free filling of furnace chambers of a coke oven, which requires a small footprint, can compensate for large deviations in the position of the filling openings and is suitable for retrofitting existing coke oven systems.
  • the object is achieved in that the inlet funnel of the filling telescope and associated with the Greeierteil lifting device are attached to a support frame, which is arranged along a first axis linearly adjustable within a travel frame, that the driving frame on rails, which are fixed to the underside of the coal hopper, is arranged horizontally movable along a second axis and that at the top of the support frame, a seal is arranged, which surrounds the inlet funnel of the Golfteleskops, cooperating with a horizontal flange on the circumference of the outlet of the horizontal screw conveyor and horizontal adjustment movements of the inlet funnel relative to the outlet of the horizontal screw conveyor permits.
  • the filling holes are arranged in the furnace roof of a coke oven in equidistant intervals and in the direction of travel of the coal filling carriage in alignment. From this ideal case, the real conditions on a coke oven deviate regularly. Especially with older coke ovens, the positional deviations of the filling holes in both axes (X, Y) are often more than 50 mm.
  • the device according to the invention is based on the consideration to compensate for deviations of Grelochachsen in the X and Y directions by a horizontal adjustment of the filling telescope.
  • the filling telescope according to the invention is decoupled, including its vertical lifting device from the outlet of the horizontal screw conveyor and arranged in a chassis, which is composed of a traveling frame and a linearly adjustable within the traveling frame support frame and horizontal compensation movements in two axes.
  • the support frame and the driving frame are independently movable in mutually perpendicular axes. Positional deviations of the Grelochrahmen can be compensated for by gradual and sequential movement of the traveling frame and the support frame or by simultaneously adjusting these components.
  • the construction height of existing chassis and support frame chassis is low, so that even older coke ovens can be retrofitted with the device according to the invention.
  • a small mass in the adjustment of the Greskops to move which simplifies the technical implementation of the inventive concept.
  • the filling telescope After the filling telescope has been positioned by adjusting the traveling frame and the support frame exactly above a filling opening, the filling telescope performs by the lifting a pure vertical movement in the direction of Golflochrahmens and passes without any inclination to rest in the Greierhornen. The result is a good seal on the Greieren so that no emissions during the filling process can get out into the environment.
  • the rails extend to guide the traveling frame in the direction of movement of the coal filling carriage (Y-direction), while the supporting frame is guided transversely thereto in the direction of the furnace chamber axes (X-axis) movable on the running frame.
  • the traveling frame and the supporting frame are preferably arranged in one plane. Such an arrangement results in a very low construction height of existing chassis and support frame chassis.
  • the traveling frame and the supporting frame are expediently composed of U-profiles, wherein rollers are mounted on the supporting frame, which run in the U-profiles of the driving frame.
  • the traveling frame is also equipped with rollers and runs in a carriageway, which is fastened below the horizontal screw conveyor of the coal filling carriage.
  • the rails for the traveling frame made of U-profiles, which are suspended with carriers on the coal filling and open at the side. The rollers mounted on the traveling frame engage in the open on one side U-profiles and run in these rails.
  • the support frame carries the complete Drteleskop including the filling telescope associated vertical lifting device.
  • the lifting device for the filling telescope has a guided on a vertical support lifting frame, which is movable by means of a hydraulic adjusting device along the vertical support and connected by pendulum elements with the telescopic base.
  • a hydraulic adjusting device along the vertical support and connected by pendulum elements with the telescopic base.
  • the Vertical support of the lifting device is attached to the support frame with lateral offset to the horizontal screw conveyor.
  • a seal is provided at the top of the support frame surrounding the inlet funnel of the Greskops and rests during the coal filling at a horizontal flange on the circumference of the outlet of the horizontal screw conveyor.
  • the seal is operatively adjustable such that the seal during a horizontal adjustment of the filling telescope has no physical contact with the adjacent flange surface and sealingly abuts the flange during the coal filling.
  • the arranged at the top of the support frame seal may be formed in particular as a membrane, as a bellows or tubular seal, which is arranged in an annular space and can be expanded with compressed air or other pressure medium.
  • the inlet funnel of the Greskops expediently has a cylindrical portion which is surrounded by a cylindrical portion of the telescopic lower part.
  • a circumferential seal is also arranged, which is preferably operatively changed and allows a substantially contact-free adjustment movement of the telescopic lower part.
  • the peripheral seal may, like the seal at the top of the support frame as a hose, bellows or membrane formed and connected to a pressure source. During working movements of the filling telescope in the horizontal or vertical direction, the seals are depressurized, so that the parts to be sealed against each other are free to move.
  • the seals are pressurized with compressed air or another pressure medium. By applying pressure, the seals bulge outwards and press against the associated surfaces of the parts to be sealed. In this way, an optimal tightness during the filling process is ensured.
  • Hydraulic actuators are preferably used for the horizontal positioning movements of the support frame and the travel frame.
  • hydraulic adjusting devices are connected to the support frame and the driving frame, which are equipped with path measuring devices.
  • the hydraulic actuating devices can be connected to a machine control of the coal filling carriage, are stored in the position information for the position of the filling openings in the furnace roof of the coke oven.
  • the deviations of the Grelochrahmen in the X and Y direction of the ideal position are detected metrologically on each Golflochrahmen and deposited in the machine control of the coal filling car.
  • the Grecoskop can be adjusted individually with the device according to the invention already while driving the Kohle divellwagens or alternatively after positioning the Kohle hypollwagens on the furnace chamber to be filled so that the filling telescope is centered to the Grelochrahmen and can be lowered by a pure vertical movement in the Grelochrahmen.
  • the pure vertical movement accounts for lateral movements and inclinations of telescopic components of the filling telescope. This ensures that all components of the filling telescope function optimally and that no emissions are released into the environment during the filling process.
  • a further embodiment of the device according to the invention provides that the hydraulic actuating devices cooperate with an optical measuring device, which is arranged on the coal filling carriage and detects the actual position of the filling openings. The measurement data are forwarded directly to the control of the hydraulic cylinders, which then move the filling telescope horizontally in a position associated with the Grelochrahmens position.
