Definitions

  • the invention relates to a device for separating Light materials from mineral raw materials, especially from Sand and gravel, with a loading arrangement for the Raw material feed, one of the separation of the coarse sand serving inner chamber as coarse sand room and with an over an overflow designed as an inclined surface to the Coarse sand room connected, sorting the fine sand according to the fluidized bed outer chamber as Fine sand room and one associated with the outer chamber Overflow for the light materials, the task arrangement one centered over one in the inner chamber arranged and leaving an outer annular gap Impact body ending feed tube includes.
  • a generic device is in EP 0 508 335 A2 described; with the configuration described known device the pretreatment of the Avoid raw material feed so that an immediate Feeding of extraction or pre-screening coming raw material in the separator is possible.
  • large amounts of water can occur adversely affect the task, since such large Water volumes heavily load the coarse sand area and either too coarse material in the fine sand room transport or also fine sand shares over the Take the fine sand room with you into the light material overflow.
  • the invention is therefore based on the object Device with the generic features in this way improve that with the material feed, even suddenly, larger amounts of water entering the separator are manageable without the separation success of the device is impaired.
  • Feed pipe an eccentrically arranged inlet to the tangential flushing of the raw material task and at its the end facing away from the impact body has an overflow channel and a the space between the end of the feed tube and the impact body bridging and in the pipe axis adjustable perforated basket for setting the Flow resistance is arranged, depending from the one set via the position of the perforated basket Separation cut of the overflow of the feed arrangement Overflow channel with the fine sand room or alternatively with the Material overflow is connected.
  • the grain size the one that gets into the overflow channel with the excess water Solid particle is over the additionally between the end the feed tube and the impact body arranged perforated basket adjustable, with the help of which the flow resistance for the raw material entry as a measure for the separation cut of the cyclone-like inlet defining back pressure is adjustable.
  • the overflow channel either be connected to the fine sand area, with which the The advantage is that a good application with a partial relief of the coarse sand area from the Fine sand is applied, or the overflow channel can be directly connected to the light material overflow, so the excess water including the mud-like Fine components relieving both the coarse sand and the fine sand area is also derived directly.
  • the overflow channel connected to the fine sand room is according to an embodiment of the invention provided that the overflow channel to the coarse sand space facing end of the inclined overflow surface between Inner chamber and outer chamber is connected.
  • the ends of the individual plates each an equal distance from Have trough surface and the opposite ends of the Plates arranged in a horizontal plane and by one spaced enclosures are enclosed.
  • the separator consists of a cylindrical inner chamber 10 with a feed arrangement 11.
  • the inner chamber 10 has one at its lower end tapered withdrawal area 12 with a controllable deduction 13, which via a mechanism 14 too is press; as not shown, are on the outside Circumference of the inner chamber 10 feed lines for the supply of Arranged underwater.
  • the inner chamber 10 with a ring surrounding it at a distance is one
  • the outer chamber 23 is arranged, the inner wall 24 of which Surrounds outer wall 20 of the inner chamber 10 at a distance.
  • Outer chamber 23 This distance between the inner chamber 10 and outer chamber 23 is bridged by an overflow called as Outer chamber 23 formed inclined overflow surface 26 is.
  • a nozzle base 27 is arranged in the outer chamber 23, the individual in a manner not shown Segments, with each individual segment of the Nozzle base 27 a via a mechanism 29 or associated electronics controlled discharge member 30.
  • the outer chamber 23 with an inlet 31 for the provide the required underwater.
  • At the top of the Outer chamber 23 includes an overflow 32 with trigger 33 for the Overflow water and the washed out light substances.
  • the task arrangement 11 consists of a centrically above the Inner chamber 10 arranged feed tube 15, which is longitudinally displaceable. Inside the Feed tube 15 is in the illustrated Embodiment arranged a feed pipe 16, which an inlet arranged eccentrically to its central axis 17 for tangential flushing of the raw material feed having.
  • the separation grain size in the Feeder 11 set at about 0.5 mm what at the same time the grain size between the coarse sands and corresponds to the fine sands, so the excess water with fine sand components to the pipe socket 43; of the The rest of the raw material feed passes through the feed pipe 16 on the impact body 19 and spread over this until it arrives in the annular gap 21, where there depending on the set flow rate a Grain size separation of the raw material feed at a Grain size between 2 mm and about 0.5 mm results.
  • the coarse sands with a grain size of more than 0.5 mm sink into the discharge area 12 of the inner chamber 10 as Coarse sand area and are deducted 13 in regulated form.
