Definitions

  • the invention includes an inclined elevator and a metallurgical plant.
  • the invention relates to a transport system for loading a metallurgical melting vessel with charge material.
  • a transport system is required to achieve a short cycle time when filling a metallurgical melting vessel with charge material, preferably scrap.
  • This transport system has a container which is detachably attached to a vehicle. With such a transport system, the container can be filled with charging material at another location and then fixed on the transport system. Discharging the feed material into a metallurgical melting vessel is accomplished by opening a vessel door through an opening mechanism associated with the vessel and then tilting the vessel. After being placed on the transport system, the opening mechanism must be connected to a power supply.
  • the EP3027780B1 shows such a transport system.
  • the object of the present invention is to create a transport system that does not require an opening mechanism on the container and the container does not have to be connected to a power supply.
  • the task is solved by the tilting frame, which has an opening unit.
  • the container flap has a driver nose which is threaded into the opening unit when the exchangeable container is placed on the tilting frame.
  • the opening unit moves the container nose such that the container flap can be moved between the closed position and the open position.
  • the container such as a container, should be designed in such a way that it takes the required amounts of charge material for a metallurgical vessel.
  • the driver lug is designed similarly to a pin, for example, and the opening unit has a groove-like design which engages in one another when the container is placed on the tilting frame.
  • the design can also have other configurations, the only important thing being that the driving lug and the counterpart on the opening unit mesh and that reliable and safe movement of the container flap between the closed position and the open position is made possible. It is thus also conceivable that the driver lug is designed similar to a groove and the opening unit has a counterpart similar to a pin.
  • the tipping frame has a guide unit for more precise positioning of the container on the tipping frame, which also makes it easier to thread the driver lug into the opening unit.
  • This guide unit is intended to pre-center the container when it is placed on the tilting frame. In a metallurgical plant, the container is often put on by means of a crane. A guide unit is used to make positioning easier and faster.
  • the opening unit performs a rotary movement.
  • the container flap is preferably rotatably mounted and is opened by the opening unit in a rotary motion.
  • An expedient embodiment provides that the opening unit is driven via a hydraulic cylinder, hydraulic motor, electric motor and/or a servo-electric cylinder.
  • a further preferred embodiment provides that the tilting frame has a locking device for securing the container against slipping.
  • an inclined elevator which includes a guide system and the transport system described above, which can be moved along the guide system.
  • the object is achieved by a metallurgical plant which includes a metallurgical melting vessel and the inclined elevator described above.
  • FIG 1 is a schematic metallurgical plant, with a retaining shaft 31 for retaining scrap, a metallurgical melting pot 30 and an inclined elevator 1 is shown.
  • the container 2 is shown schematically, which is placed on the tilting frame 3, the container 2 being fastened to the tilting frame 3 with appropriate fastening means (not shown).
  • the container flap 5 can be moved in a rotatable manner about the axis 13 via an arm 5a.
  • the arm 5a has a driver lug 5b, which is threaded into the opening unit 6.
  • the opening unit 6 has a plate 14 which includes two guide rails 11a and 11b.
  • the driver lug 5b is threaded between the two guide rails 11a and 11b.
  • the container flap 5 is moved by the opening unit 6 using the hydraulic cylinder 8 .
  • the container flap 5 is in the 2 shown in a closed position.
  • a guide unit 20 is additionally provided.
  • the guide unit 20 consists of a guide nose 22 which is attached to the container 1 and two guide brackets 21a and 21b which are attached to the tilting frame 3.
  • the container 2 is first pre-centered by the guide lug 22 and the guide brackets 21a and 21b, so that the threading of the driver lug 5b into the guide rails 11a and 11b is facilitated.
  • the container flap 5 is shown in the open state, ie in an open position. It is easy to see how the opening unit 6 moves the driver lug 5b with the guide rails 11a and 11b.
