Definitions

  • the invention relates to a device and a method for ash removal from a tunnel kiln car equipped with fired moldings.
  • the construction effort to accomplish this should be kept very low, so that a brick plant equipped with coal firing must be kept clean and operating problems caused by ash are avoided.
  • this is achieved in that a plurality of nozzles and suction channels leading out of the tunnel furnace are arranged directly in the tunnel furnace, preferably in front of the furnace exit, in the tunnel furnace ceiling and / or in the side walls, by means of which the bearings on the tunnel furnace car and the trimmings Ash can be blown off and extracted.
  • suction duct arranged approximately opposite each other and to arrange the nozzles and suction ducts alternately in rows, so that there is a constant change between blowing and suctioning.
  • nozzles are nozzle tubes with nozzle openings arranged at different heights and to provide the suction channels with preferably slot-like suction openings arranged at different heights.
  • suction ducts projecting close to the bottom of the kiln car should preferably be arranged at the exit of the tunnel kiln, and these should be movable so that they are not damaged by individual moldings.
  • the method according to the invention for ash removal from a tunnel kiln car equipped with fired moldings is characterized in that the tunnel kiln car and the trimmings are blown by means of nozzles arranged preferably in front of the exit of the tunnel kiln car and an air flow is blown off, which is suctioned off by means of the nozzles arranged approximately opposite one another.
  • the air flows between two adjacent nozzles and suction channels which are assigned to one another should be directed in opposite directions, and the air flows can also be blown in through the nozzles in pulses.
  • the device designed according to the invention for ash removal from a tunnel kiln car equipped with fired moldings and the method according to the invention make it possible with simple means to remove the ash which is inevitably obtained in coal firing, without the brickwork and the environment being contaminated thereby.
  • nozzles and suction channels are provided directly in the tunnel furnace, it is possible to blow off and vacuum the ashes before the tunnel furnace car leaves the tunnel furnace, so that no ashes can escape to the outside.
  • the tunnels In this way, oven wagons and the trimmings can be adequately freed from the adhering ash, the risk of contamination is therefore extremely low, since tunnel oven wagons equipped with ash are not moved outside the tunnel oven. In this way, operational disruptions caused by ash are reliably prevented in the brickworks, and this is also kept clean.
  • the nozzles 11 are formed from nozzle tubes arranged in the ceiling 2 of the tunnel furnace 1, into which nozzle openings 12 are incorporated at different altitudes.
  • the suction channels 13 are equipped with a large number of suction slots 14, through which the ashes enter the channels 13 which are led out of the tunnel furnace 1.
  • the lining 4 of the tunnel kiln cars 2 is divided into individual packages 5, 5 'and 5 ", so that longitudinal slots 6 and 6' are formed.
  • the nozzles 11 and the suction channels 13, which are alternately arranged in a row, can thus also enter the slots 6 and 6 'of the trimming 4. In this way, particularly intensive cleaning can be achieved since the paths to be covered by the air flow are short and this impinges on the part to be cleaned with high kinetic energy.
  • the ashes adhering to the tunnel kiln car 2 and the trimmings 4 ′ are torn away and taken up by the suction channels 13 due to the air flows which are directed in opposite directions to one another between a nozzle 11 and a suction channel 13 and which can expediently also be passed in pulses.
  • the moldings thus leave, especially since further suction shafts 15 are arranged to be movable on all sides at the furnace exit, in order to take up any ash residues that may still be present and not to be damaged by fallen moldings, cleaned the tunnel furnace 1, so contamination of the brickworks is reliably avoided.
