Definitions

  • the invention relates to a device for the distribution of bulk material in at least two containers, in particular two arranged above the gout of a blast furnace bunker.
  • the distribution of bulk material in two arranged above the gout bulk bunker wherein the feed of a bunker is preferably carried out during the emptying of the other bunker and vice versa. It goes without saying that the invention is generally suitable for the aforementioned distribution of bulk material in at least two containers.
  • the present invention is therefore an object of the invention to provide a bulk material distribution, which is extremely efficient, simple and particularly space-saving, especially low builds.
  • An essential point of the present invention is thus that the deflecting flap is forcibly guided along its trajectory at the trailing and trailing end along paths extending parallel to the container inlet openings.
  • the wear resistance of the device is substantially increased and achieved a correspondingly long life.
  • the container inlet openings extend at a predetermined angle, in particular of about 90 ° to each other, wherein the deflecting flap is mounted above these two inlet openings swinging back and forth, in the aforementioned manner.
  • the drive of the deflecting flap is preferably carried out via a pivot lever which is coupled with a pivot drive on the one hand and with the deflecting flap on the other hand.
  • a concrete embodiment is shown in claim 4.
  • the guideways are arranged on the container inlet openings facing (bottom side) of the Umlenkklappe and protected by this against bulk material.
  • the articulation of the aforementioned pivot lever takes place on the underside, ie the protected against bulk material side of the deflecting flap. This contributes significantly to the life of the deflection and distribution device according to the invention.
  • the guiding and pivoting facilities are also Protected against excessive contamination, so that the maintenance intervals can be extended.
  • the upper side of the deflecting flap is preferably provided with an "armor". This is done by welding of highly wear-resistant material. Specifically, reference is made in this regard to claim 7.
  • stops for a maximum approach or a minimum distance between the deflecting flap and the respective container inlet opening when closing the same can also be provided.
  • separate seals are provided for sealing the container inlet openings.
  • each separate closure flaps may be assigned, which are preferably arranged inside the container. In this case, they should preferably be movable laterally and upwardly away from the container inlet openings when they are released, in order to avoid a collision when the containers with the closure flaps are highly filled.
  • the deflecting flap is located below a central opening of a filling funnel above the at least two container inlet openings.
  • This embodiment is very compact overall, builds low and is also wear-resistant due to the special arrangement of guideways and pivot lever.
  • Fig. 1 shows a furnace head or Gichtverschluß 10. This is located above the gout 11 of a blast furnace not further illustrated. Above the furnace head, two material bins 12 ', 12 "are placed parallel to one another, into which bulk material is introduced via a conveyor system, here material chutes 13. From the material bunkers 12', 12", the gout 11 is then fed via a rotary chute 14 and distributor or feed chute 15. The rotary chute 14 is rotationally driven about a first vertical axis of rotation 16. At the outlet, ie at the lower end of the rotary chute 14, the distributor or feed chute 15 is rotatably mounted about a second, relative to the first axis of rotation 16 laterally offset vertical axis of rotation 17 rotationally driven. The corresponding rotational movements of the aforementioned chutes are indicated by the arrows 18, 19.
  • the rotary drive of the two chutes 14, 15 is effected by associated gear 20, 21, which are arranged for reasons of temperature and dust protection within a cup-shaped sealing space 22.
  • the upper, the rotary chute 14 associated transmission is still coupled to an electric motor drive not shown here.
  • a here only indicated geared connection 24 between the rotary chute 14 associated gear 20 and the feed chute 15 associated transmission 21 is on the in the DE 199 29 180 C2 referenced construction.
  • the underside of the gout space 22 is closed by a particularly heat-resistant plate 23.
  • This plate is a kind of heat shield. It also includes the housing of the feed chute 15 associated transmission 21st
  • the heat shield 23 is rotatably mounted together with the rotary chute 14 about the axis 16. For this purpose, an additional rigid connection in the form of a connecting rod 25 between rotary chute 14 and heat shield 23 is provided.
  • the two material bunkers 12 ', 12 each have a separate bottom opening 26, 27 through which the rotary chute 14 is fed either from the material bunker 12' or from the material bunker 12".
  • the bottom openings 26, 27 are alternately openable.
  • the corresponding closing flaps are in Fig. 1 denoted by the reference numerals 28, 29. In Fig. 1 the left-hand closing flap 29 is shown in the open position, while the closing flap 28 assigned to the right-hand material bunker 12 'is in the closed position.
  • the device for distributing bulk material into the two material bins 12 ', 12 " which is designated above by the reference numeral 30.
  • This comprises a bulk material deflection flap 33 assigned to the two inlet openings 31, 32, by means of which alternately the two container inlet openings 31, 32 are openable or closable, in such a way that when opening the one inlet opening (in Fig. 1 left inlet opening 32), the other inlet port 31 is closed by the Umlenkklappe 33 and vice versa.
  • the Fig. 1 further reveals that the bunker inlet ports 31, 32 are directed at an angle of approximately 90 ° to each other, and that the baffle flap 33 is mounted above these two inlet openings 31, 32 swinging back and forth.
  • the inlet openings 31, 32 are still separate closure flaps 34, 35 associated, in each case on the inside of the container. These separate closure flaps 34, 35 are, if necessary, laterally and upwardly movable away from the container inlet openings 31, 32 upon release thereof.
  • Fig. 1 For example, the left inlet opening 32 is shown in the open position, while the right inlet opening 31 is closed both by the deflection flap 33 and by the closure flap 34 assigned to this inlet opening.
  • the closure flaps 34, 35 are protected in their closed position against the application of bulk material. Accordingly low is the wear of the flaps. They can be made with a long service life of relatively inexpensive material.
  • the deflecting flap 33 is, moreover, arranged below a central opening 36 of a filling funnel 37 above the two bunker inlet openings 31, 32 and is effective.
  • Fig. 1 shows very well that it is in the illustrated and described bulk material distribution device is an extremely compact and low-wear construction.
  • the bulk material of the upper side of the Umlenkklappe 33 is preferably still armored to increase the wear resistance.
  • all sensitive pivot and guide parts are located on the protected against bulk underside of the Umlenkklappe 33, in particular the FIGS. 2 and 3 good to recognize.
  • the deflecting flap 33 is forcibly guided on its trailing and trailing end along parallel to the bunker inlet openings 31, 32 extending tracks 38, 39.
  • this forced guidance of the deflecting flap 33 is arranged by guide rollers 40, 41, which are arranged at the leading and trailing ends or at the two outer ends of the leading and trailing edges, and are approximately parallel to the cross-sectional planes of the bunker inlet openings 31, 32 extending guideways or grooves 38, 39 defined on the other.
  • said pivot lever 42 at the bunker inlet openings 31, 32 facing bottom de Umlenkklappe 33 on the one hand and in the corner region between the two bunker inlet ports 31, 32 on the other hand is pivotally mounted.
  • the pivot lever 42 is rotatably connected to the drive shaft of a pivot drive, not shown.
  • Fig. 3 can be seen very well that when pivoting the Umlenkklappe 33 from the right closed position to a left closed position the aforementioned corner region associated guide roller 41 along the still open bunker inlet opening 32 associated guideway moves upward in the direction of the arrow 44, while the other, the trailing edge of the Umlenkklappe 33 associated guide roller 40 is moved in the direction of the arrow 45 down.
  • the deflecting flap 33 is thus forcibly guided "over-the-corner", whereby this forced guiding is determined by the pivoting drive 42, 43.
  • the deflecting flap 33 preferably consists of a frame formed by rails, in particular U-profile rails, in particular rectangular frame whose flat sides are defined by steel plates.
  • the bulk-loaded top is preferably "armored", i. provided with a highly wear-resistant material. As a rule, such an armor is obtained by welding of highly wear-resistant material.
  • the deflection flap is still provided with sealing strips to a hermetic seal of one or the other inlet opening 31 or 32 to receive. This is absolutely necessary because of the additional flaps 34, 35 but not.
  • the movement of the separate flaps 34, 35 laterally upward is in Fig. 2 indicated by corresponding movement lines 46, 47. These lines of movement are approximately S-shaped.
  • the closure flaps 34, 35 are associated with corresponding guide members, preferably in the form of a corresponding multi-lever transmission. This type of movement of the closing flaps 34, 35 makes it possible to fill the bunkers 12 ', 12 "close to the inlet openings 7.
  • the described bulk material distributing device makes the construction relatively compact, ie low.
  • the construction described is characterized by a high wear resistance and accordingly high durability.
