Definitions

  • the invention relates to a device for separating Light materials from mineral raw materials, especially from Sand and gravel, with a fluidized bed method working sorting area, with a job for that Raw material, a discharge for the cleaned material and an overflow for the light materials.
  • a generic device results from the company publication "LINATEX - LINARD", 04.83 from the Schauenburg company Maschinen- und Anlagenbau GmbH as from the execution 2 of patent specification DE-A-34 18 492.
  • the known device consists of a cylindrical single chamber container with an almost flat bottom and one in it arranged discharge for the cleaned sand.
  • Above the Soil is a jet floor through which underwater flows arranged, above which during operation of the device the so-called fluidized bed space builds up, in which under Utilization of the fines contained in the raw material feed the sand has a very high turbidity density, which organic impurities contained in the raw material feed, especially heavily carbonized wood leaves so that the contamination with the overflow water be washed out.
  • the known device has the disadvantage that that the raw material feed is very solid have to be; this is the case with the extraction of dry matter to be cleaned Raw material a task directly via a belt conveyor and in the case of wet extraction in the form of a sand / water mixture a pre-thickening of the raw material feed, for example required in hydrocyclones.
  • the wet extraction is predominant, the known device requires the upstream connection of a additional thickening level with a corresponding one mechanical and in terms of controlling the composition of tasks procedural effort.
  • the invention is therefore based on the object Generic device to improve such that no restrictions, especially when it comes to the raw material feed regarding the sands and gravel to be cleaned exist and that the cleaning or separation success is further improved.
  • the basic idea of the invention is that the Two-stage device with an inner chamber with a assigned task arrangement for the raw material task and the separation of the coarse sand and the inner chamber ring-like surrounding and separated by an overflow External chamber for sorting fine sand is formed, the outer chamber being according to the fluidized bed process working sorting area is formed followed by the overflow for the light materials.
  • the device allows a high throughput because the sorting stage is significantly relieved.
  • there are no special requirements to set the solids content in the raw material task are; it can dilute the raw material in almost any be abandoned because in the inner chamber next to the partition the coarse sands also an equalization of the overflow into the outer chamber with the sorting area takes place or can be set.
  • an outer annular gap centrally free impact body arranged, with a feed tube ends at a distance above the impact body.
  • the surface of the impact body sloping towards the annular gap be formed, which may alternatively be useful the surface of the impact body with a general tendency to To form an annular gap wave-shaped, whereby a certain Sedimentation of the raw material feed before entering the Annular gap occurs.
  • Feed tube on with a feed line for the raw material connected feed pipe arranged; still the task tube arranged longitudinally so that the distance between the exit of the raw material from the feed pipe and can adjust the impact on the impact body.
  • the dimensions of the inner chamber or associated impact body and the setting of the flow velocity in the annular gap are such pretend that the grain size of the in the inner chamber separation between coarse and fine sands is between 2 mm and 0.5 mm.
  • the invention thus deviates from a simple overflow control in the form of an edge trained overflow and looks at mutual Distance from inner chamber to outer chamber one as inclined Area trained overflow. That is the advantage connected that in turn an equalization on the overflow surface overflow of fine sands with those in them impurities still contained; at the same time certain sedimentation and pre-thickening of the Material overflow because the overflow water faster drains away. So the sorting success is that of the outer chamber assigned sorting area further improved.
  • the nozzle bottom with a controllable Fine sand discharge is provided. It can be done after a Embodiment of the invention may be provided
  • the height of the nozzle base is infinitely adjustable.
  • the area ratio is preferably between 1: 3.5 to 1: 5.5.
  • the device consists of a cylindrical inner chamber 10 with a feed arrangement 11.
  • the inner chamber 10 has at its lower end a conical taper Trigger area 12 with a controllable trigger 13 which can be actuated via a mechanism 14.
  • a mechanism 14 Like Figure 2 better can be seen are on the outer circumference of the inner chamber 10 Lines 22 are arranged for the supply of underwater.
  • the task arrangement 11 consists of a centrically above the Inner chamber 10 arranged feed tube 15, which is longitudinally displaceable is set up. Inside the feed tube 15 is a feed pipe 16 which is arranged on its upper end with a feed line 17 for the raw material feed connected is; in addition, a vent 18 in the Task arrangement 11 formed.
  • baffle 19 arranged at a General inclination outwards a wavy surface having. Between the outer wall 20 of the inner chamber 10 and the impact body 19 remains an annular gap 21.
  • 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. This distance between the inner chamber 10 and outer chamber 23 is bridged by an overflow 25, which as to the outer chamber 23 is inclined surface 26 is formed.
  • the Outer chamber 23 has a nozzle base 27 arranged accordingly the representation in Figure 2 from six individual Segments 28 exists. Each individual segment 28 of the nozzle base 27 has 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 operation of the device according to the invention takes place Supply of the raw material feed via the feed line 17 and that supply pipe 16 arranged in the feed pipe 15; due to the longitudinal displaceability of the feed tube 15 can Distance between the exit of the raw material and the Baffle 19 are adjusted so that at this point a corresponding equalization of the task flow in Adaptation to the subsequent grain size separation possible is.
  • the material hits the impact body 19 and distributed over this until it gets into the annular gap 21 where depending on the flow rate set there a grain size separation of the raw material feed a grain size between 2 mm and about 0.5 mm.
  • the coarse sands with a grain size of more than 0.5 mm sink into the discharge area 12 of the inner chamber 10 and are discharged in a regulated manner via the trigger 13.
