Definitions

  • the present invention generally relates to a charging installation of a shaft furnace, comprising in particular two storage hoppers and a receiving hopper for feeding material into the storage hoppers.
  • the present invention further relates to a method for charging a shaft furnace using such a charging installation.
  • At least one storage hopper is provided in the charging installation for receiving material, such as e.g. coke or sinter, from a skip or conveyor belt and temporarily storing the material therein before it is fed to the shaft furnace.
  • material such as e.g. coke or sinter
  • more than one storage hopper generally two, sometimes three
  • these are arranged in parallel and allow a sequential charging of the shaft furnace.
  • Material is fed into one storage hopper, while another storage hopper has its material emptied into the shaft furnace.
  • any material fed into the shaft furnace is first stored in such a storage hopper. The material must therefore be distributed into one or the other of the storage hoppers.
  • This distribution may be achieved by means of a distribution rocker which has a central pivot and is actuated to either feed the material into the first storage hopper or the second storage hopper.
  • a horizontal translating receiving hopper may be provided for guiding the material into the correct storage hopper.
  • a pivoting receiving hopper may be used. Such a pivoting receiving hopper is arranged to pivot about a pivot axis and thereby align its outlet with either one of the inlets of the storage hoppers.
  • a charging installation of a shaft furnace comprises a first storage hopper and a second storage hopper, arranged in parallel with respect to each other; each of the first and second storage hoppers having an inlet for receiving material and an outlet for feeding material into the shaft furnace.
  • a receiving hopper is arranged upstream of the first and second storage hoppers, the receiving hopper being pivotably arranged about a horizontal pivoting axis and configured for receiving material therein and for distributing the material to one of the first and second storage hoppers.
  • the receiving hopper comprises an inlet for receiving material from a feed apparatus and an outlet for feeding the material to the first and second storage hoppers, the receiving hopper being pivotable at least between two transfer positions, wherein, in a first transfer position the outlet of the receiving hopper is in alignment with the inlet of the first storage hopper and, in a second transfer position, the outlet of the receiving hopper is in alignment with the inlet of the second storage hopper.
  • a rest position is arranged between the first and second transfer positions.
  • the charging installation further comprises a material gate associated with the outlet of the receiving hopper; and an actuating mechanism associated with the material gate for opening and closing the outlet of the receiving hopper, the actuating mechanism being configured so as to actuate the material gate through the pivoting movement of the receiving hopper.
  • the actuating mechanism is configured so as to essentially close the outlet of the receiving hopper when the receiving hopper is in the rest position and so as to essentially open the outlet of the receiving hopper when the receiving hopper is in either of the first and second transfer positions.
  • the material gate prevents any rest of material - coke, sinter, or other - that may be remaining in the receiving hopper from falling onto a closed sealing valve of one of the storage hoppers or from falling between the two storage hoppers.
  • the actuating mechanism of the material gate causes the latter to be self-closing, i.e. there is no need for a separate actuator for the material gate.
  • the material gate is actuated by the pivoting movement of the receiving hopper. Thus, no activation or control of the material gate has to be foreseen in the shaft furnace sequence; there is no risk of failure of the material gate.
  • the movement of the material gate about its pivot point is preferably in a direction opposite to the direction of the receiving hopper about the pivoting axis of the receiving hopper.

  • the actuating mechanism 32 can be more closely described by referring to Figs 2, 3 and 4, which show an enlarged view of a receiving hopper in three positions.
  • the receiving hopper is in its first transfer position, i.e. the outlet 26 is open and communicates with the inlet 14 of the first storage hopper 12.
  • the actuating mechanism 32 comprises a first link element 34 and a second link element 36.
  • the first link element 34 has a first end 38, a second end 40 and a pivot point 42 located between the first and second ends 38, 40.
  • the first link element 34 preferably comprises a first portion 44 and a second portion 46 arranged in an angled configuration, the pivot point 42 being arranged at a meeting point between the first and second portions 44, 46.
  • the material gate 30 is connected to the first end 38 of the first link element 34.
  • the first link element 34 is pivotably connected with the pivot point 42 to the receiving hopper 18.
  • the receiving hopper 18 is moved clockwise into the second transfer position. This movement causes the material gate 30 to move anticlockwise and open the outlet 26 of the receiving hopper 18.
  • the second transfer position of the receiving hopper 18 is illustrated in Fig.3. Once the receiving hopper 18 is in its second transfer position, material can be charged into the second storage hopper 12'.

Abstract

L'invention concerne une installation de chargement (10) d'un four vertical comprenant une première trémie de stockage (12) et une deuxième trémie de stockage (12') parallèles ; chacune des première et deuxième trémies de stockage (12, 12') ayant une entrée (14, 14') permettant de recevoir de la matière et une sortie (16, 16') permettant d'alimenter le four vertical en matière. Une trémie de réception (18) est placée en amont des première et deuxième trémies de stockage (12, 12'), la trémie de réception (18) étant placée de façon à pouvoir pivoter autour d'un axe de rotation horizontal (22) et conçue pour recevoir de la matière et pour distribuer la matière à l'une des première et deuxième trémies de stockage (12, 12'). La trémie de réception (18) comprend une entrée (24) permettant de recevoir la matière d'un appareil d'alimentation (20) et une sortie (26) permettant d'envoyer la matière aux première et deuxième trémies de stockage (12, 12'), la trémie de réception (18) pouvant pivoter entre au moins deux positions de transfert, dans une première position de transfert, la sortie (26) de la trémie de réception (18) étant alignée avec l'entrée (14) de la première trémie de stockage (12) et, dans une deuxième position de transfert, la sortie (26) de la trémie de réception (18) étant alignée avec l'entrée (14') de la deuxième trémie de stockage (12'). Une position neutre est située entre lesdites première et deuxième positions de transfert. Selon un aspect de la présente invention, l'installation de chargement (10) comprend de plus une trappe à matière (30) associée à la sortie (26) de la trémie de réception (18) ; et un mécanisme d'actionnement associé à la trappe à matière (30) permettant d'ouvrir et de fermer la sortie de la trémie de réception (18), le mécanisme d'actionnement étant conçu pour fermer pratiquement complètement la sortie (26) de la trémie de réception (18) lorsque celle-ci est en position neutre et pour ouvrir pratiquement complètement la sortie (26) de la trémie de réception (18) lorsque celle-ci est en première ou en deuxième position de transfert. Le mécanisme d'actionnement (32) est conçu pour actionner la trappe à matière (30) grâce au mouvement de pivotement de la trémie de réception (18).
