Definitions

  • the invention relates to a strain-free stationary furnace door operation for a coke oven plant of the "heat recovery" type, through which a vertical opening of the coke oven chamber doors without use of a Koksofenbedienungsmaschine is possible, the deviations of the traction elements of the furnace door operation of the target assemblies, which are characterized by the
  • the invention also relates to a method for the expansion-free, stationary furnace door operation of a coke oven plant of the type "" which results in expansions of the transfer devices and undesired tensile force reinforcements, which result from differences in the adhesion forces of the coke oven chamber during closure, by the use of expansion-poor transmission devices and tension elements.
  • WO 01/18150 A2 describes a system of coke oven chambers, secondary heating chambers, cooling air ducts under the coke oven chambers, air supply ducts, control devices for the admission of air into the air supply ducts, exhaust gas collecting ducts, coal loading machines loaded from the ceiling of the coke oven compartments, expressing machines, which express from one side of the coke oven chambers, and fire trucks that receive the coke on the opposite side of the coke oven chambers, coke oven chamber doors, door opening and closing mechanisms, coal storage devices, a quench tower, and an exhaust gas collection channel to the boiler devices.
  • This teaching discloses an opening and closing mechanism for coke oven doors, which opens the doors vertically by pulling force with a hydraulic drive device, wherein the pulling force is transmitted with ropes, which is converted via pulleys in a horizontal tensile force, so that the pulling device horizontally and against the rope can transport a counterweight.

  • the device is preferably used on both sides of the coke oven chamber, so both on the machine side and on the coke side.
  • the rigid tension element is preferably a pull rod.
  • the transfer device is low-stretch or in a preferred embodiment almost free of strain.
  • the strain-free transmission device is preferably a chain of low-expansion steel segments. Under low-stretch is to be understood that the chain changes when opening or closing in its entire length only a few millimeters.
  • the connecting mechanism is preferably a bracket, which is fastened to the towing vehicle via a hinge, and which is pivoted on demand by a lever, whereby the pull hook of the pull rod is displaced when the pull rod is displaced into a holder provided for this purpose engages in the bracket, which allows trouble-free passage of the towing hook with an untwisted bracket.

  • a pulling gripper cam as taught in the prior art, with a potentially breakable hook is no longer required.
  • a coach is advantageously provided for each coke oven chamber to be opened Koksofenscht.
  • another coaster is advantageously provided, which is pulled by the corresponding drawbar, so that both opposite coke oven chamber a coke oven chamber can be operated independently or simultaneously.
  • the pull rod can be driven arbitrarily.
  • the drive unit is preferably provided at least at one end with a hydraulic cylinder. This is driven by the hydraulic pump of a hydraulic unit.
  • the pull rod is provided at least one end with a geared motor unit.
  • the pull rod or the tension element can be equipped with any draw hooks or projections for transmitting the tensile force.
  • the towing hooks can be adjusted horizontally in the suspension position on the tension element in the longitudinal direction.
  • the pull rod is typically stored on rollers for improved mobility.

However, this is preferably equipped with an automatic mechanism, is moved by the bracket or the slider in the position required for the tensile force.
  • a train carriage which is equipped with a connection mechanism and which can be moved along a guide device along the coke oven chamber front, remains without request in the idle state, and which is characterized in that
  • the train carriage opens the coke oven chamber door via a low-expansion transmission device, and closes the coke oven chamber door when the tractor vehicle retracts.
  • the tension element or the drawbar can be driven arbitrarily for horizontal displacement, which is used as a force after deflection in the vertical direction to open or close the coke oven chamber doors.
  • the tension member can be moved by way of example by a hydraulic cylinder, which is driven by a hydraulic pump of a hydraulic unit.

This is measurable above all on the overstroke device of the hydraulic cylinder on the tension element, which is set by way of example to an overstroke of at most 150 mm. This overstroke compensates for both the different door lift and the chain extension.
  • the drive unit can run temporarily or permanently, depending on the duration of the coking process and the number of coke oven chambers to be operated.

Abstract

L'invention concerne un actionnement de porte stable, sans allongement, pour une cokerie du type sans récupération ou à récupération de chaleur, permettant une ouverture verticale des portes des chambres d'un four à coke sans recourir à une machine de manipulation du four à coke, et permettant d'éviter les écarts que présentent les éléments de traction de la commande de porte de four par rapport aux configurations nominales, dus à des allongements des dispositifs de transmission, ainsi que les augmentations indésirables des forces de traction qui sont causées par des différences de forces d'adhésion des portes des chambres de carbonisation lors de leur fermeture, par l'utilisation de systèmes de transmission et d'éléments de traction à extensibilité réduite. L'invention concerne également un procédé pour l'actionnement stables, sans allongement, d'une porte de four de cokerie du type à récupération de chaleur, faisant appel à des éléments de traction rigides et des dispositifs de transmission à extensibilité réduite pour l'ouverture et la fermeture automatique des portes des chambres de fours à coke.
