Definitions

  • the invention relates to a coke oven door for horizontal chamber coking ovens with a door body, which consists of an elastic, thin-walled sealing plate, the edge of which carries the sealing cutting edge is held on the sealing frame on the sealing bolt on the furnace frame, as with one on the inside of the sealing plate and at a distance arranged coking plate protruding into the furnace.
  • coke oven doors that have been used almost exclusively so far consist of a heavy cast body that can weigh up to 5 t and more.
  • Coke oven doors of this type which generally have a heavy ceramic stopper of about 0.4 m in depth on the inside, are difficult to handle and require correspondingly complex operating machines.
  • the coke oven door known for example, from P 31 38 4o6.4, has a significantly lower weight, so that it is easier to handle and can also be positioned more precisely in front of the coke oven.
  • the door body itself is connected to the chamber frame at more than two connection points or pressed against it.
  • the known coke oven door consists of a sealing plate, which represents the actual door body and which has sealing edges at the edge, which are stressed by pressing elements or pressed against the chamber frame, these pressing elements being opposed to a continuous sealing frame which is supported by a U-shaped profile or the like. is formed against the locking bolts arranged distributed over the height. In order to ensure the most uniform possible support, six or more locking bolts of this type are provided.
  • Such a coke oven door is characterized by the much lower weight and also by a very high flexibility, since the door body, as described, only consists of the thin-walled sealing plate. It therefore adapts to the respective course of the furnace frame with little effort.
  • the furnace frames like the doors, are bent out of their position due to the thermal stress, which can result in leaks, since the sealing cutting edge can then no longer be pressed onto the furnace frame sufficiently tightly.
  • this is not the case with the known elastic doors with the sealing plate as the door body.
  • the elasticity of the continuous door body is further increased and at the same time its weight is reduced by the fact that on the inside there is no longer any stone plug, but a coking plate held at a distance from the door body by spacers.
  • the invention has for its object to provide an overall flexible coke oven door that is safe and guarantees perfect adaptation of the door body to the respective oven frame even when exposed to high heat and long service life.
  • the sealing frame is designed as a pressure compensation linkage which is flexible in the direction of the furnace frame and which is arranged to act on the sealing plate at predetermined intervals along the length thereof.
  • Coke oven doors designed in this way are characterized by astonishingly low weight, which is due both to the light design of the sealing plate serving as the door body and to the u.a. coking plate serving as a spacer.
  • the entire door body is now so flexible that it can completely adapt to the shape of the furnace frame over its entire length.
  • the sealing plate lies tightly everywhere on the furnace frame or the sealing blade attached to it can ensure a tight seal of the interior of the furnace from the atmosphere over the entire height of the coke oven door.
  • the flexibility of the entire door body not only has the advantage that it can fit tightly against the more or less bent furnace frame, but also enables the destruction of impurities sitting on the furnace frame, because the individual section of the sealing plate or the sealing cutting edge is included high force is pressed onto the furnace frame. This high force is generated by suitable units and passed on to many points of the coke oven door via the pressure compensation linkage.
  • the pressure compensation linkage consists of nested old, pressure equalizing jacks acting on each other or on both sides of the longitudinal edge of the sealing plate. These pressure compensation trestles ensure the even transmission of the contact pressure and the bending of the sealing plate, which can be achieved over short distances, in accordance with the bending of the furnace frame.
  • a pressure compensating linkage can be designed such that when the contact pressure is applied or passed on in a targeted manner and advantageous flexibility, only a slight weight load of the overall system occurs.
  • the pressure compensation linkage has pressure compensation brackets with its claws on the sealing plate, which are articulated with their backs to other pressure compensation brackets acting as a connecting block or distributor block.
  • Such a pressure compensation linkage is very flexible in the direction of the furnace frame, while it automatically freezes when the coke oven door is placed in front and when it is pressed on.
  • the pressure compensation linkage in a divided manner and to assign a locking bolt on both sides.
  • four pressure compensation rods are therefore required, which are generally of the same design and can therefore be interchanged.
  • the necessary contact pressure can be applied to the sealing plate and the sealing cutting edge in advantageously short ways, using these appropriately designed pressure compensation rods.
  • the pressure compensation linkage appropriately have four each their two claws on the sealing plate acting pressure compensation brackets, which are supported by two connecting brackets and the distributor bracket on the locking bolt.
  • the required contact pressure is generated in a simple manner and for the pressure compensation rods arranged on both longitudinal sides of the sealing plate or is evenly transmitted to them by inventively connecting the pressure compensation rods assigned to a locking bolt via a bridge part, which can be changed at a distance from the locking bolt via an adjustment unit is.
  • the adjustment unit is expediently a spindle which can be operated in a simple manner by the door lifting machine. The spindles of both locking bolts are actuated simultaneously, which ensures a uniform and simultaneous pressing of the sealing plate.
  • the claws of the pressure compensation blocks assigned to the upper edge of the sealing plate are connected to the sealing plate, for example welded.
  • the same expediently also applies to the pressure compensation linkage assigned to the lower locking bolt.
  • an activatable pressure element in a coke oven door designed in this way to use.
  • the invention provides that an activatable pressure element is arranged between the sealing plate and the claws of the pressure compensation blocks, wherein the pressure compensation blocks are each supported on an associated locking bolt which is displaceable in height.
  • the pressure to be applied to the sealing blade by the pressure element is evened out via the pressure compensation stands, because the pressure element is not only supported on the locking bolt, but rather on the several support points now available. Because a stable sealing frame is dispensed with and the pressure compensation linkage is used instead, the flexibility of the coke oven door is also considerably improved here, since it can advantageously be adapted to the course of the oven frame in the shortest possible way.
  • the pressure compensation stands are equipped with a hook comprising the respective locking bolts, which are opened opposite to the locking hooks. The end regions of the locking bolt are thus advantageously guided uniformly and stored safely, regardless of whether the tensioned state or the relaxed state is given.
  • the bolts are pulled down so that they lie behind the bolt hook, after which the pressure element is then acted upon and leads to tensioning of the entire system.
  • the locking bolts can advantageously be moved with a single device, in that the locking bolts that can be moved into the hooks have lugs according to the invention, to which flat irons are screwed for connection to the next locking bolt. When one of the locking bolts is actuated, the other locking bolts are also automatically moved.
  • a pressure element can also be a centrally arranged pressure element.
  • Each locking bolt is expediently assigned a pressure element arranged in the center of the sealing plate and clampable between the sealing plate and locking bolt, preferably a rubber bellows arranged in a hat-shaped pot.
  • An advantageous securing of the entire coke oven door, in particular in the area of the upper and lower horizontally running sealing strip, is there according to the invention achieved by that six locking bolts are distributed over the height of the sealing plate, the top locking bolt about 2oo mm and the bottom locking bolt about 35o mm from the horizontal part of the sealing cutting edge and arranged parallel to it. With such an arrangement, such high forces can be transferred into this area at the same time by the pressure elements arranged in the area of the locking bolts that the tightness of the coke oven door is ensured overall.
  • a further U-profile with regular recesses in the flanges and supporting the U-profile with the pressure element is arranged with the flanges on the sealing plate between the U-profile having the pressure element and the sealing plate is.
  • This second U-profile forms a type of cooling strip, because so much air can circulate in the remaining space between the flanges that the pressure element above it is only partially stressed by the heat emanating from the coke or the coke oven. Since the second U-profile is only supported with the flanges on the correspondingly heated sealing plate or door body, dangerous temperature stresses can also be prevented in this way.
  • the second U-profile is designed so that it can be inserted into the upper U-profile receiving the pressure element. As a result, the pressure element acts directly on the lower U-profile and thus on the sealing plate.
  • an insulating mat is arranged on the inside and outside of the sealing plate.
  • An insulating mat has hitherto also been provided on the inside of other known coke oven doors. Its main task was to ensure that the gas flowing up between it and the coking plate was not cooled as far as possible to this side.
  • the insulating mat now also provided on the outside protects the units arranged on the outside and contributes to the fact that the sealing plate as a whole receives an approximately equal temperature from the outside and inside, so that it advantageously maintains its shape over the entire height.
  • the arrangement of the insulating mat can be provided in a particularly advantageous manner if the sealing plate is cantilevered in the region of the furnace opening and the insulating mat is arranged in the recess formed in this way.
  • the edging also leads to an increase in the stability of the thin-walled sealing plate, which has advantages overall with regard to the manageability of the door.
  • the invention is characterized in particular by the fact that the service life can be increased by a targeted and uniform introduction of the pressing forces into the sealing plate or sealing strip and by lower loading of the pressing elements.
  • the high flexibility of the coke oven door is increased so that seen over the entire height of the coke oven door there is an exact adaptation of the course of the sealing plate to that of the furnace frame.
  • the pressure equalization is rods attached so that the desired adjustment of the sealing plate to the course of the furnace frame is guaranteed over the entire height.
  • Units can be used when converting coke ovens to the existing facilities.
  • the retrofitting work when using pressure elements that can be activated and thus a large number of locking bolts and locking hooks are such that the system as a whole still offers significant advantages over the previously known prior art.
  • the continuously flexible door body allows the coke oven door to be adapted overall to the respective course of the oven frame and thus ensures a consistently uniform sealing of the coke oven from the atmosphere.
  • the critical areas at the top and bottom of the coke oven door are also secured, since the pressure forces are increased here due to the denser arrangement of the claws of the pressure compensation brackets, or because the pressure elements in this area also ensure uniform tensioning by the arrangement of the locking bolts or the pressure compensation brackets wear.
