Definitions

  • the invention relates to a device for cleaning refractory-lined conveyor troughs for molten metals and slags and relates in particular to the devices for moving the device along the conveyor trough during processing of the trough wall.
  • a device for cleaning conveyor troughs by means of rotating chains is known.
  • This device can be moved along the channel with wheels which are guided in rails on both sides of the channel.
  • the arrangement shown there of two guide rails in the form of wide channels for the four wheels is however unsuitable.
  • the hall floor and in particular the subsurface next to the gutter deforms, which leads to permanent deformation of the rails fixedly arranged or formed in or on this subsurface, so that perfect tracking parallel to the gutter and an even support all wheels cannot be reached. Irregularities in the route not only complicate the operation of the device, but also adversely affect the cleaning process.
  • such rails result in an increased risk of accident when operating the channel. Furthermore, such rails can become unusable if the channel overflows.
  • the object of the invention is therefore to improve the devices for moving the device with regard to the resulting changes in the ground and to avoid the risk of accidents. This problem is solved according to the main claim.
  • the subclaims represent preferred further developments, in particular with regard to the training of the proposed rail.
  • a three-point support ensures the stable position of an object even on uneven ground.
  • the chassis of the device the overall length of which is relatively short in relation to its width, is to be guided as parallel as possible to the middle of the channel on a background which is constantly changing under the influence of heat.
  • lateral forces also affect the chassis from the cleaning process.
  • the present invention solves this problem in a simple manner, which is also suitable for rough operation on, for example, a blast furnace.
  • the guidance of the frame according to the invention is also particularly advantageous compared to railless devices such as excavator vehicles on which a cleaning head is mounted.
  • 1 shows a section through the conveyor trough with a view of the device for cleaning the trough
  • 2 shows one end of a guide rail
  • Fig. 3 is a view of a conveyor trough with an adjacent guide rail and an indicated device for cleaning.
  • the cleaning head of the device shown consists of a drum 1, to which chains 2 are fastened, the slag and loose components of the refractory material of the lining 4 knocking off on the wall of the conveying trough 3 when the drum rotates, as for example in DE-PS 32 25 015 is described.
  • the device has a chassis 5. On this a column 30 can be moved transversely to the channel. On the column 30, a carriage 31 is movably guided in the vertical direction. The lateral displacement of the column 30 and thus also of the cleaning head 1, 2 takes place via a motor 32, preferably by means of a chain hoist 33. The height adjustment of the cleaning head 1, 2 is done by the motor 34, and this is also due to the rough, dusty operation a blast furnace a chain 35 useful.
  • a motor 6 is provided on the slide 31 for driving the drum 1.
  • the device also has a control station 36.
  • a cable drum 37 can be provided for supplying the electrical energy to the device.
  • the frame 5 On one side of the frame 5 there are preferably two wheels 21 individually driven by traction motors 29.
  • the wheels 21 run on the guide rail 20.
  • non-driven side guide rollers 22 are provided which can rotate about vertical axes and run laterally on the guide rail 20 and provide lateral guidance when the wheels 21 are driven and when cleaning the channel take over the frame ' 5 acting side forces.
  • a single non-driven support roller 23 is arranged on the frame 5.
  • the support roller 23 can have a larger diameter than the wheels 21, so that they over - i _
  • a separate drive of both wheels 21 has the advantage that even in the event that the frame 5 is seated somewhere and one of the wheels 21 is lifted off the rail 20, a drive via the other wheel 21 is still possible, so that it Elimination of the difficulty encountered at least 'can. It should be noted that the area of the conveyor trough is still so hot during the cleaning process that it is not easily accessible.
  • the one-piece guide rail 20, which is, for example, 20 m long, is removed during normal operation of the conveyor trough and can easily be removed by a crane and very easily reinserted for the cleaning process by means of the bolts 24 and the elongated holes 25. Also, the cleaning device itself is provided by a crane onto a waiting place "during normal channel operation of the conveyor trough. Exist in a blast furnace operation, several approximately equally long conveyors, such apparatus and the guide rail can be used alternately in these channels for cleaning.
  • Fig. 3 shows in simplified form a conveying trough for a blast furnace with an inserted beside her Füh * - * ungsschiene 20 and the indicated device.
  • FIG. 3 also shows suction devices 40, through which gases and / or smoke can be sucked off during gutter operation and which draw off a part of the dust produced during cleaning.
  • the invention is not limited to the cleaning device with chains on a drum shown in the examples, but can also be used in gutter cleaning machines that work with other cleaning heads.

Abstract

Un dispositif connu de nettoyage de rigoles de transport à revêtement ignifuge pour métaux fondus et scories, par exemple dans des hauts fourneaux, comprend un cadre guidé sur deux rails et déplaçable en sens longitudinal au-dessus de la rigole de transport. Selon l'invention, un rail de guidage (20) facilement démontable est agencé d'un seul côté de la rigole de transport (3). Le chariot mobile (5) comprend du côté du rail de guidage (20) deux roues (21) entraînées par des moteurs (29) et deux paires de rouleaux de guidage latéral (22) et, du côté opposé au rail de guidage (20), un rouleau libre de support (23). Grâce à cet agencement, des irrégularités du terrain adjacent à la rigole de transport n'affectent pas le guidage parallèle du dispositif par rapport au milieu de la rigole. Le dispositif et le rail peuvent être enlevés après l'opération de nettoyage, ce qui évite des risques d'accidents provoqués par le rail de guidage (20) pendant l'exploitation de la rigole.
