Definitions

  • the invention relates to a coal transport and filling system for coking furnace batteries with a conveyor arranged above the battery in its longitudinal direction, e.g. B. a conveyor belt or continuous conveyor, for transporting the coal from the coal tower or a free transfer point to the individual furnaces and with connection of the conveyor to a movable service car, the u. a. serves as a transfer device for the emission-free filling of coal in the furnaces.
  • a conveyor belt or continuous conveyor for transporting the coal from the coal tower or a free transfer point to the individual furnaces and with connection of the conveyor to a movable service car, the u. a. serves as a transfer device for the emission-free filling of coal in the furnaces.
  • the supply unit serves to transport the coal from the coal tower to the respective furnace and consists of the number of filling containers corresponding to the filling holes, which collect a total of coal filling.
  • This supply unit runs on its own rails independently of the coke oven battery.
  • the service unit moves on the furnace ceiling only a few meters to the next furnace chamber to be filled and has a relatively low weight.
  • DE-AS 12 99 592 describes a device for loading a horizontal-chamber coking furnace battery, a frame being movable on rails directly above the furnace ceiling and four conveyors lying parallel to one another being mounted on the frame.
  • the furnace roof is heavily loaded both in terms of space and weight.
  • DE-C-885 691 describes a charging device on coke ovens for optional tamping or pouring operation with a coal tower lying over the path of the tamping and loading machine, with the coal from the coal tower in the case of pouring operation via a conveyor device which can be moved in the transverse direction of the battery into one Intermediate bunker and from there into the filling car.
  • a conveyor device which can be moved in the transverse direction of the battery into one Intermediate bunker and from there into the filling car.
  • the object of the invention is to propose a generic coal transport and filling system for coking furnace batteries, in which the carbon stripping devices can be dispensed with and the battery is largely relieved in terms of space and weight and the other problems indicated do not occur.
  • the conveying device is designed to be movable overall in the longitudinal direction of the battery under the outlets of the coal tower or the free transfer points. Only a short distance is required, which corresponds to the distance between two ovens to be filled in succession.
  • the discharge head at the end of the conveying device is connected to the service trolley according to the method above the furnace to be filled in order to fill the coal into the furnaces.
  • This service trolley serves on the one hand as a transfer device for the emission-free filling of the coal into the furnaces, whereby a gas-tight seal is made in relation to the filling hole and the conveying device, on the other hand all necessary operating and cleaning devices with which the conventional filling trolleys were equipped are arranged on the service trolley.
  • this service car has only a very low weight and is only moved a short distance from one oven to another, possibly together with the conveyor.
  • the conveyor device can be suspended in particular on longitudinal rails under the battery hall roof and can be moved via drives.
  • the furnace ceiling is completely freed of coal transport facilities that have to travel the long way from the coal tower to the individual furnaces.
  • the coal transport and filling devices are moved, especially when empty, in order to keep the loads and vibrations on the masonry low.
  • it may be useful for the coal containers on the service car to consist of closed coal transfer hoppers with a permanent coal residue cushion.
  • a conveyor belt scale can also be arranged on the discharge head of the movable conveyor device. This means that the elaborate weighing bunkers under the coal tower can be dispensed with and the exact filling quantity for each individual oven can still be determined.
  • the invention further provides that a cross conveyor with adjustable cross-section outlet openings is arranged under the longitudinal conveyor belt or the service car. These outlet openings are adjusted so that the amount of coal calculated for each fill hole is allocated.
  • a bulk flow meter is provided between the cross conveyor, which is designed, for example, as a trough chain conveyor, and the transfer hopper. This has the task of weighing the amount of the respective filling holes to be filled and of transmitting them to the central control room. If the target quantity is not reached or exceeded, the bulk flow meter is connected to the drives for the gate valves for automatic regulation of the filling quantity or for changing the cross section of the outlet openings.
  • the movable conveyor belt With a view to avoiding emissions when the coal is transferred to the conveyor belt, it has proven expedient to equip the movable conveyor belt with preferably stationary suction devices arranged at the transfer point of the coal. These suction devices can be arranged both above the conveyor belt in the vicinity of the transfer point and below.
  • suction devices can be arranged both above the conveyor belt in the vicinity of the transfer point and below.
  • the vacuum cleaner nozzle is arranged so that the bottom of the tin tray is not touched directly.
  • the suction nozzle is held at a constant distance from the sheet metal trough via guide rollers.
  • the suction nozzles below and above the conveyor belt are connected to a stationary dedusting system installed nearby or in the coal tower.
  • the in Solids that accumulate dust filters can be returned to the coal bunkers by an attached pheumatic transport device.
  • the coal conveying device can also alternately serve for charging two coke oven batteries if the coal tower or the transfer point is arranged between them.
  • the invention provides that the conveyor belt has a discharge head at both ends and the conveyor device of the conveyor belt is reversible.
  • FIG. 1 shows a schematic side view of two adjacent coke oven batteries (1), (1b) with a coal tower (13) arranged between them above the furnace ceiling.
  • the conveyor device consisting of a conveyor belt (8) can be moved in the longitudinal direction of the battery (see arrows).
  • the entire conveying device is suspended from the longitudinal rails (10) of the battery hall roof (12) and has the discharge heads (9), (9a) at both ends. Between the discharge heads (9), the closed transfer funnels (5) and the filling holes (2) a gas-tight seal is made for the filling process.
  • each battery can have its own service trolley, so that a furnace of the battery (1) is first filled with the help of the service trolley (4), while the service trolley (4a) shown in dashed lines on the battery (1b) Service work is carried out and is connected to the discharge head (9a) in preparation for the filling process.
  • the filling process for an oven on the battery (1b) can be started by reversing the conveying device of the conveyor belt (8).
  • the service cars (4a) and (4b) shown in dashed lines are each shown above an end furnace of the battery (1b), which also means the maximum travel distance of the Conveyor becomes clear.
  • FIG. 2 shows in particular the suspension of the conveyor device with conveyor belts (8) lying one next to the other via drives (11) on longitudinal rails (10).
  • the conveyor belts (8) end in the discharge heads (9) covered with a housing, the discharge funnels of which are connected to the cross conveyor (6) with a dustproof closure (7) with telescopes.
  • This cross conveyor (6) forms a closed unit with the transfer funnels (5) and has suitable metering devices for filling the required amounts of coal into the individual filling holes.
  • the automatic adjustment can take place from the control room or can be operated directly by the bulk flow meter (15).
  • the coal flow on the way from the discharge head (9) over the trough chain conveyor (6) to the transfer hopper (5) is shown in dashed lines.
  • a carbon residue cushion (22) is held in the transfer funnels (5) in order to avoid possible filling gas emissions.
  • the end support screws (16) the coal is filled into the individual filling holes (2) of the coke oven battery (1) via vertical downpipes.
  • FIG. 3 shows a cross section through an oven battery with a battery hall roof (12) supported separately outside the battery.
  • the conveyor (8) is suspended from this battery hall roof on longitudinal rails (10) and only the service trolley (4) is supported on the furnace ceiling by the rails (3).
  • the weight of the conveyor is only a fraction of that of the previous conventional filling car. This makes an overall lighter and less expensive construction possible. Above all, however, the load on the masonry is very low with a view to increasing the chamber volume of the coke ovens.
  • FIG 5 the suction device according to the invention at the transfer points of the coal to the conveyor belt (8) is shown schematically.
  • the coal dust whirled up when it hits the conveyor belt is extracted via a suction nozzle (18).
  • Under the conveyor belt there is a fixed trough (20) connected over its entire length for collecting the trickle coal falling from the lower conveyor belt.
  • a stationary vacuum cleaner nozzle (19) protrudes into this tin trough, which does not directly touch the bottom of the tin trough (20), but is kept at a distance by means of lateral guide rollers.
  • the vacuum cleaner nozzles (18) and (19) are connected to a stationary dry dedusting via a suction line (17).
  • the sheet metal trough (20) fixedly connected to the conveying device is automatically guided past the suction nozzle (19), so that the sheet metal trough is cleaned regularly.
