Definitions

  • the present invention relates to a device to separate a material mixture Materials with different specific weights according to the preamble of claim 1.
  • a device of this type is known from DE 41 40 584 A1 known. This device is in the transition area between the feeder and the separator an air blowing device is provided. With the help of On the one hand, airflow becomes the relatively lighter Mixing components for a so-called viewing device blown down while the heavier blend ingredients past the air flow in front of the sighting device fall on a conveyor belt.
  • the materials separated with the known viewing device are thus for a possibly subsequent Recycling process won in the state in which it is from are fed to the feed device.
  • a problem arises when the separated Mix components loaded with materials are that a constructional approval of the recyclate oppose. These are in particular: organic and not weather-resistant caking or deposits; furthermore is liable the heavier and larger mixture components under certain circumstances also sand and dust, so that at the recycling results in falsifications in the recipe can.
  • the object underlying the present invention consists of a separating or sorting device of the generic type to specify at which simultaneously with a density-dependent separation process a washing process is carried out so that the heavier components of the mixture are conveyed cleanly cleaned can be and where the water consumption and the throughput performance meets the ecological-economic requirements correspond.
  • this task is characterized by the characteristics of the Claim 1 solved.
  • a separating device of the generic type in this regard is further formed that the air flow to Separating the mixture components by means of a liquid flow, especially a water jet which is the heavier mixture components in Fall through washes and the lighter mixture components washed away and reusable in the fractions Sand and light / waste materials to be deposited separates.
  • a particular advantage with regard to the use of water as a separation medium is still to be seen in the fact that a larger grain spectrum is processed can be.
  • the liquid inflow device consists of a plurality of pipe elements arranged side by side, which is rectangularly deformed on the output side in particular are, so that an optimal flow quality respectively an optimal flow cross section over the Width of the side by side and thus as Wide-slit nozzle-acting tubular elements are created.
  • the liquid inflow device is angular, optionally also adjustable in height, so that it is adaptable to the current mixtures. Basically the liquid flow is directed over a weir, that is equally adjustable in angle and height and is laterally displaceable.
  • the separation device shown in FIG. 1 a material mixture is used in the following with their mode of operation or intended use Function explained.
  • a to be separated or by gravity and Material mixture to be separated from light materials is included Aided by a conveyor belt 1 or the like. From conveyor belt 1, this is (in part still uneven distributed) material mixture of a conveyor or Vibrating channel 2 fed where the material mixture is evened out. From the vibrating trough 2 then the loosened up and evened out Material mixture towards a liquid inflow device 4 (arrow m) being a fender or optionally a slide 3 is provided, which the material leads in a certain relationship.
  • the liquid inflow device 4 consists of a Plural (to form a kind of slot die) juxtaposed, firmly connected Pipe elements 5, preferably on the output side are rectangular in particular deformed square and thus ensuring a closed, homogeneous flow profile.
  • the liquid inflow device 4 or the tubular elements 5 are relative to the mudguard or aligned to slide 3, that a diagonally directed against the material flow Liquid flow occurs (see arrow X).
  • a weir 6 which can be moved in height, angle and side and has an overflow threshold 7 assigned or subordinate, via the flowing liquid flows away.
  • the entire The liquid cycle is self-contained and works from a central tank 16. From this tank 16 the process liquid 17 becomes the liquid inflow device 4 pumped (see pump 18). From the pipe elements 5 emerging and the tub for the Belt conveyor 8, the dewatering screen machine 10 and the sand recovery device 12 flowing Liquid is drained through an integrated piping system returned to the tank 16. With regard but that the recycled mixture components Liquid remains bound for the total amount Process liquid is lost is the tank 16 a - not shown - liquid quantity control unit assigned over which the liquid shortage is balanced.
  • the pump 18 itself is included preferably depending on the amount and speed the process fluid adjustable.
  • the liquid inflow device 4 and the weir 6 adjustable to integrate and to the extent that the Flow angle of liquid flow and the slope of the weir 6 are variable.
  • the exit surface of the liquid inflow device 4, and the position of the weir 6 with respect vertical positioning adjustable shape; weir 6 is also laterally displaceable.
  • the selectivity for the separated Mix components directly from the exit speed the liquid at the liquid inflow device 4 depends - is - as already mentioned - provided the pump 18 pressure and to be designed to regulate the quantity.
  • the liquid inflow device 4 is in detail explained with reference to FIG. 2. It exists - as already mentioned - from a plurality (here four) of parallel juxtaposed, fixed relative to each other Pipe elements 5. These pipe elements 5 are about a common reservoir 20 with liquid supplied, which in turn via the pipe 17 or the pump 18 is supplied with liquid becomes. For homogenizing the flow conditions and to equalize the pressure conditions is the Distribution tank 20 upstream of an expansion tank 21 (see detailed illustration A-A).
  • the Pipe elements 5 each have a flow meter 22 and a manometer 23 with a control flap 24, so that the liquid profile at the exit of the tubular elements 5 (in the transition area between the feed device in the form of the slide 3 and the separating device) can be optimally adjusted.
  • the one from the Pipe elements 5 existing or prefabricated Kit is in the mounting frame for the invention Separating device mounted in a fixed position, in the course of the tubular elements 5, namely at the transition from the horizontal alignment for upward alignment, however, a piece of hose 25 is inserted, around the liquid exit surface of the liquid inflow device 4 the current working conditions to be able to optimally adjust accordingly.
