Definitions

  • the invention relates to a device for coke oven operation, consisting of a scaffold that can be moved along a coke oven battery and a jib machine that can be moved in the transverse direction on the scaffold, the horizontally rotatable and vertically swiveling jib is provided with coolant channels and at its free end a connection head for preferably several tools, including at least a combination of a scoop and scraper device for removing coke from each furnace chamber.
  • the invention relates in particular to those operations on coke ovens which, in addition to the scheduled loading and emptying of the oven chambers, have to be carried out on modern horizontal chamber ovens.
  • These are to be understood primarily as large-capacity furnaces which have a chamber height of approximately 8 m and a chamber length of approximately 16 m and a volume of 35-40 t, but lengths, the heights of approximately 4 m and heights, are also suitable for the invention reach of 11 m.
  • large-capacity ovens particularly large forces are introduced into the chamber lining by the coke-pressing machine, which forces the chamber walls of the large-chamber furnaces to a greater extent than the smaller-sized chamber walls during the ejection of the chamber lining.
  • a device for removing coke from the oven chambers is already known (DE-PS 807 091), which is intended to facilitate the manual work when scraping out the stuck coke cake from the oven chamber from the coke side.
  • a portal-like scaffold is provided, which can be moved on a track, the rails of which on the Master gear and relocated to special foundations next to the fire truck track.
  • the upper part is used to move a scraper belt that can be moved into the furnace chamber and can also be swiveled vertically.
  • the movable part of the scraper belt is provided with blades for scraping the coke out of the furnace chamber.
  • a short belt is assigned to him as funding, which takes over the coke scraped out and discharges it into the fire truck, which must therefore be kept ready under the portal.
  • a device does not take sufficient account of the practical requirements that must be observed when coke cakes are stuck in the oven chambers.
  • the known device can only process the coke cake stuck on the coke side and only with the soleplate released because of the risk of damage from the blades of the scraper belt.
  • This has the disadvantage that the stuck coke cake for the push rod of the squeezing machine cannot be straightened on the machine side, so that a renewed pressing attempt on the tilting of the rod and the blocking of the rod transmission based thereon fails.
  • the soleplate of the coke is not freely loaded, there is a risk that the coke cake will get stuck again in the oven chamber if the printout attempt is repeated.
  • the heat of the coke cake during the entire working time which is necessary for the elimination of the furnace malfunction, loads the device itself and the coke cake carriage, which means that considerable damage to these devices can be expected in the event of greater difficulties.
  • the coke cake is not only stuck in the oven chamber, but also in the coke cake carriage.
  • This state is in K okskuchen enclosureswagen particularly critical because by atmospheric oxygen and the Teramik the coke begins to burn and the car can be destroyed by the effects of heat in a short time.
  • the scraper belt of the previously known device requires that the coke cake carriage is first moved to the side. However, this is only possible if the coke cake is torn off. Most of the time, however, this fails because the drive power of the lead carriage is too weak.
  • the glowing coke not only lies in the coke cake guide, but also falls between the anchor stands and the machine chassis. This causes additional damage to the anchor stands and the master aisle ceiling. Even if the machine can be moved, the glowing coke must be manually removed from the coke cake carriage. This work is dangerous and cannot be carried out in a sufficiently short time. Damage to the machines can therefore generally not be avoided.
  • this device is not very suitable for eliminating the described furnace faults, because the processing of the coke cake in the furnace chamber from the machine side is just as impossible as the safe removal of the glowing coke discharged from the furnace chamber.
  • the device is mobile, it must use the master gear, which is suitable for absorbing static and dynamic loads from such a device only to a limited extent. The same concerns also arise against the use of the anchor stands to fix the device.
  • the invention has for its object to provide a device of the type known as known, which allows the processing of the coke cake from both sides of the chamber, that is from the machine and the coke side, as well as a safe removal of the coke discharged from the furnace chamber .
  • this object is achieved in that the scaffold designed as a valley is provided on its vertical supports with controllable and individually driven undercarriages for trackless operation on the track bodies on the coke and machine sides, and a coke-extinguishing device with one reaching to the respective furnace sole adjustable feed conveyor, as well as a receiving device for the extinguished coke with a discharge conveyor.
  • the invention enables these rail areas to be driven on both sides of the battery.
  • the machine can be used on either side of the coke oven battery as required;
  • the combination of scoop and scraper device can also be used to produce a suitable contact surface for the push-out rod on the coke cake stuck in the chamber. Since the machine is also provided with its own take-over and processing facility for coke fire for the elimination of malfunctions, normal furnace operation can be resumed immediately after an malfunction has been eliminated.
  • This new machine replaces the previously used devices for scraping out the coke fire over the furnace sole and for removing graphite deposits, e.g. in the form of compressed air showers and mechanical clearers, in particular rods and air lances through the boom machine, with which the necessary work processes are carried out mechanically from a control center. This avoids the heat effects previously associated with this work on the operating personnel and the risk of accidents, which, due to falling graphite rinds and strong sparks, impair manual work and make this impossible at all in large-scale furnaces.
  • the machine according to the invention is capable of being independent of the energy network on the machine and coke sides of the battery, for those required in each case To take operations in the most favorable position without endangering their stability. Therefore, the boom of the machine can be used as a carrier of a repair platform, which avoids the time-consuming moving and securing of work platforms, which are usually used for the monitoring and adjustment of cross anchors, chamber frames and chamber locks of the coke oven battery as part of the constant care and maintenance work got to.
  • the boom can also be used like a hoist.
  • the new device is therefore expediently designed such that the portal has an upper platform, under which rails of a positively driven carriage are arranged, on which the slewing ring, the swivel drive of the boom and a cabin surrounding a control station are shifted are, under the platform an intermediate platform is provided in the portal, which is used to move a water-filled coke receptacle with a suction hood into which the extendable coke rubs between the conveyor, the discharge conveyor being arranged under the coke receptacle.
  • the possibility of the boom allows each part of the half furnace chamber including the from the coke side or machine side To achieve furnace walls by utilizing or combining the movements of the machine on the portal and the movements of the boom on the slewing ring.
  • a swivel drive acting on the nucleus and a horizontal joint are arranged on the slewing ring of the jib machine, which receives the rigid jib, which consists of several sections and contains a coolant supply and coolant return, on the arm near the swivel joint
  • Swivel drive is a drive for supplying kinetic energy for a combination of shovel and scraper device which can be connected to the connection head via a further horizontal joint.
  • this structural element can be used as a shovel but also as a scraping device by a simple pushing movement.
  • the scoop serves to pick up the coke from the furnace sole and to prevent it from being scraped out over the furnace sole as before. This protects the furnace soles and also the lower layers of the furnace walls.
  • the boom and the thrust linkage installed to actuate the bucket on the boom are constantly cooled by a forced circulation with integrated cooling, so that the functionality of the machine is not affected by the effects of heat.
