Definitions

  • a longitudinal conveyer is mounted parallel to the longitudinal axis of a battery of coke-oven chambers and includes an endless belt selectively movable in the longitudinal direction.
  • a discharge opening is formed in the bottom strand of the belt and a charging means including a funnel is fixed to the belt around the opening.
  • the charging means also includes a connection device mounted on the funnel for selective vertical movement to connect the funnel with the charging openings of a selected chamber.
  • the present invention relates to an apparatus for charging coke-oven chambers combined in batteries and to which coal is supplied through a charging or filling device from at least one longitudinal conveyer having a conveying surface and arranged in parallel with the axis of the battery of oven chambers.
  • preheated coal is blown through a charging pipe and branch lines into the oven chambers.
  • Steam, coke-oven gas or an inert gas are used as a carrier gas in this system.
  • Such apparatus is disadvantageous in that it requires a complex pipe switch, which is susceptible to failure, for each oven chamber in order to draw off coal from the main supply bin.
  • the second prior art system employs scraper, chain or similar type longitudinal conveyers arranged in a conduit of box-type cross-section to feed the coal over a conveying surface to the oven chamber to be filled.
  • the coal is branched off from the longitudinal conveyers to the oven chamber through a stationary filling device provided on each oven chamber.
  • a single filling device is provided, which device can be tranported to separate chambers anad connected to closable connections of the longitudinal conveyers.
  • a number of shutting-off elements is required between the longitudinal conveyer and the filling device, which number corresponds to the number of oven chambers.
  • This object is achieved in accordance with the present invention by employing a belt displaceable in the longitudinal direction and which has a discharge opening as the conveying surface of the longitudinal conveyer.
  • a filling or charging device connectable to the charging openings of the oven chambers is coupled to the discharge opening.
  • the connection between the longitudinal conveyer and the charging device remains closed throughout every phase of operation, that is, the connection is closed during the transportation of the charging device from an oven chamber just filled to another oven chamber to be filled. This reduces considerably the/complexity of the operating means, and the operation can be effected with simple control means from a central control station.
  • the structure of the longitudinal conveyer is such that the inner surface of the lower strand of an endless belt is employed as the conveying surface of the longitudinal conveyer.
  • the upper and the lower strands of the belt extend into guides that are arranged on the inner sides of the side walls that limit the belt laterally and form a closed conveying channel with the belt.
  • the endless belt forms simultaneously the upper and the lower walls of a gas-tight channel, wherein the coal is conveyed without a stress to the environment. Since the connection between the longitudinal conveyer and the charging device is always maintained, the escape of coal dust or coal is prevented. Accordingly, while being of simple construction, the longitudinal conveyer meets all the requirements that are placed on the modern coke-oven operation with regard to the protection of the environment.
  • the guides of the endless belt may be sealed by means of a housing attached to the side walls of the longitudinal conveyer.
  • the side walls are provided with charging openings that communicate with a coal supply bin or a coal drying vessel through distribution devices.
  • Channels conducting inert gas and comprising connecting openings to the guides of the endless belt are suitably provided on the outer sides of the side walls of the longitudinal conveyer. This prevents soiling of the belt guides and secures the continuous operational capability of the belt.
  • the charging device which advantageously includes a funnel having a shutting-off element. is coupled to the discharge opening of the endless belt.
  • the charging device has vertically movable connections for the charging openings of the oven chambers, and may differ in design depending on the specific nature and the preliminary treatment of the coal to be conveyed into the oven chambers.
  • the longitudinal conveyer can preferably be arranged along the longitudinal axis of the battery on the cover of the battery. and the charging device can possess a tube-type distribution element that branches off to the central charging openings of each chamber and which is connected to the funnel in a telescoping manner.

  • the longitudinal conveyer is arranged on a longitudinal side of the battery cover, and the funnel of the charging device has a charging opening connection that can be placed in position and removed by means of lifting and lowering devices.

  • the vertical pipes carry filling opening connections that can be displaced by means of a common lifting and lowering device.
  • the conveying surface of the transverse conveyer is perferably subdivided into conveying paths and connected to the verical pipes by means of surface slides adjustable across the width of the transverse conveyer.
