Definitions

  • the present invention relates to a drainage elevator with a base belt made of elastomeric material, with a plurality of studs which extend transversely to the longitudinal axis of the base belt and are fastened to the support side of the base belt, a compartment being formed between two adjacent studs for receiving material to be conveyed with a drive drum and a deflection drum, around which the base belt rotates endlessly, a steeply rising conveyor section and a feed section being formed.
  • a drainage elevator is used in particular to convey goods which have a very high liquid content or which are drawn from a water reservoir.
  • Conveyors of this type are used with a gradient of approximately 70 ° as steep conveyors or with an even greater gradient as vertical conveyors.
  • a special area of application for such conveyor belts is coal mining.
  • the coal is usually separated from the rock by being suspended in a liquid of high specific density, the coal floating in the liquid and the rock sinking to the bottom of a separation basin or separation container.
  • Water is usually used as the liquid, to which additives are added to increase the specific density.
  • the coal collecting in the separation basin or separation container is then conveyed out by means of the compartments of the dewatering elevator, which for this purpose is located below the water level with a large part of its length.
  • a drainage elevator of the type mentioned at the outset is known, for example, from DE 42 40 201 Cl.
  • Such a conveyor is - like all other known drainage elevators - linearly aligned, i.e. the conveyor section and the feed section form a linear load section and an equally linear return section.
  • the material to be conveyed is usually taken up under water in that the tunnels scrape the material to be conveyed from the bottom of the separation basin or separation container or from a feed chute after it has circulated around the deflection drum located below.
  • This independent pick-up of the material to be conveyed by abrading is often the reason why tunnels break or are torn off from the base belt, namely when, for example, rocks are jammed during excavation and therefore block the circulation of the tunnels hit.
  • the present invention addresses this problem, the task of which was considered to be to provide a low-maintenance drainage elevator of a lighter design.
  • This task is performed on a drainage elevator with a base belt made of elastomeric material, with several transverse to the
  • Lugs extending along the longitudinal axis of the base belt and fastened on the support side of the base belt, with a compartment for receiving between each of two adjacent lugs Conveyed material is formed, and with a drive drum and a deflection drum around which the base belt rotates endlessly, a steeply rising conveyor section and a feed section being formed, thereby solved that a conveyor shaft housing is provided which encloses the base belt in such a way that the side walls of the compartments are formed by the conveyor shaft housing, and that the feed section and the conveyor section have an angle c. include less than 180 °.
  • the drainage elevator according to the invention has, for example, an L-shape, the feed section forming the lower, smaller leg of the L-shape.
  • This form of drainage elevator is only possible in that the base belt itself has no belt side walls, since these are formed by the walls of the conveyor shaft housing.
  • the overlapping side walls of the base belt which are known, for example, from the known drainage elevator of DE 42 40 201 Cl, would block in the negative deflection against the base belt.
  • Flexible side walls as are known for example from DE 42 44 760 C2 or as sold by the applicant under the brand name FLEXOWELL, cannot be used with drainage elevators either, since such walls form a completely closed compartment as a conveying space between two neighboring ones Form tunnels from which the liquid cannot drain or cannot flow out at a sufficiently rapid rate.
  • the almost horizontal feed section of the dewatering elevator which for example has an inclination of 15 ° to the horizontal, has the enormous advantage that the material to be conveyed does not have to be grappled, but can be loaded in another way, for example from above through a loading opening in the conveyor shaft housing .
  • the coal-bearing rock can be fed to the feed section via a chute or other feed line.
  • This type of task of the material to be conveyed in turn has the great advantage of a low resistance to the task, which the workers in the Base belt greatly reduced, which is why, for example, a cheaper, lighter and less maintenance-prone and, in addition, corrosion-resistant fabric belt can be used instead of a steel cable belt. Furthermore, the danger of the tunnels being blocked and thus damaging them is avoided due to the fact that the material to be conveyed is left without a break.
  • the side walls of the compartments of the drainage elevator are formed by the conveyor shaft housing.
  • the side walls are each formed by a flange in the interior of the conveyor shaft housing, which is arranged parallel and spaced apart from the corresponding side wall of the conveyor shaft housing and closely adjacent to the side edges of the tunnels.
  • the side walls can be part of a U-profile, for example, which is placed with the open side facing down over the studs, so that the two legs of the U-shape form the side walls and the base of the U-shape on the ceiling of the conveyor shaft housing attached or part of the same.
  • a drainage channel can be provided for additional drainage of the conveyed material located in the compartment, which is delimited by one of the side walls of the conveyor shaft housing, the ceiling and the bottom of the conveyor shaft housing and by the associated flange, this associated flange being different from the ceiling descended stretches and leaves a space between the belt surface of the base belt and the free end of the flange, through which the liquid emerging from the compartment can then flow into the drainage channel, which extends parallel to the base belt over the entire length.
  • Such a drainage channel is preferably arranged on both sides of the base belt, so that the liquid can flow off to both sides.
  • a further significant reduction in the belt tensile forces is made possible by a further development of the drainage elevator, according to which the deflection of the base belt takes place at the bend between the feed section and the conveyor section in the load section by means of deflection skids instead of the known deflection drums.
  • the base belt runs in a manner known per se, i.e. as with the conventional deflection using drums, with its left and right edge area, which extends laterally beyond the width of the studs around the deflection skids.
  • the base belt is preferably guided in the entire load strand by means of guide runners arranged on the running side, which makes a further contribution to reducing the belt tensile forces.
  • guide runners arranged on the running side, which makes a further contribution to reducing the belt tensile forces.
  • the following development relates to a drainage elevator, in which a screen element is arranged between two adjacent tunnels to support the conveyed material.
  • Such screen elements are known for example from DE 38 35 619 C2 and DE 42 40 201 Cl. Those two patents essentially deal with the fastening of the screen elements to the tunnels, taking into account conventional, overlapping side walls which are attached to the tunnels.
  • the screen elements are now glued to the studs, which is only possible because the base belt itself has no side walls.
  • the press for gluing the screen element to the studs starts at the side where the side walls of conventional base belts prevent such lateral access. This gluing of the screen elements instead of the usual screw connection also helps to reduce the overall weight of the drainage elevator.
  • the base belt of the present drainage elevator has a much lower feed resistance than known belts of this type and, moreover, the risk of blocking is practically zero.
  • One consequence of this is the possibility of using lighter studs.
  • This advantage is exploited by a development of the invention, according to which the studs are formed in part and glued to the base belt.
  • the weight advantages of a one-piece stud over a two-piece stud that has a stud foot and a driving profile attached to it are obvious. With today's technology of adhesives, such bonds are extremely reliable and can be easily removed by heat wrapping if necessary.
  • the angle o. On the support side between the conveying section and the feed section is preferably approximately 120 °. This angle is determined by an inclination of the feed section from the horizontal of approximately 15 ° and by an inclination of the conveying section determined from the horizontal of about 75 °.
  • the base belt is a fabric belt, i.e. a conventional belt made of elastomeric material with a fabric insert as tension member and possibly other fabric inserts as cross reinforcement. It has already been described above that the use of a fabric belt is only possible through the construction of the drainage elevator according to the invention, since steel cables must be used as tension members at the more common higher tensile forces, with which the disadvantages described then go hand in hand.
