Definitions

  • the present invention relates to a device for Sorting, subdivision of a fraction from if necessary different sub-fractions of any kind according to density and / or grain size with at least one conveying element in particular with a plurality next to one another at least one crankshaft mounted conveyor bars.
  • Such a device is, for example, in DE 28 03 684 C2 and described in DE 100 14 812.3.
  • About two Crankshafts are individual juxtaposed Adjacent conveyor bars can be driven against each other. there the conveyor strips are arranged inclined and convey a flow of material to a discharge, taking on this way smaller fractions by appropriate Breakthroughs in the individual conveyor strips and can be transported away. Larger fractions roll down from the conveyor ledges and are transported over conveyor belts or the like.
  • the mixtures can consist of parts or fragments as well as from different materials from different size and / or density and / or grain size such as wood, preferably paper, but also metal, Plastic, rubber, rubble or the like.
  • the present invention is based on the object To create device of the type mentioned, which the disadvantages mentioned are eliminated and with which simple and effective way space-saving and inexpensive separating, in particular mixing and loosening Fractions to be separated in many sub-fractions should be improved.
  • the sub-fractions exactly with regard to their density, grain size or the like. can be determined.
  • Another arrangement should also be considered, for example of conveying elements, so that a third if necessary Sieve stage and a third separation into three individual ones Sub-fractions is possible. This is also said to be in the frame of the present invention.
  • the two-stage has proven to be particularly advantageous Device, in particular the two-stage balistic separator proven for the separation of paper.
  • the individual funding elements at least one paragraph may be provided with an overhang to to better mix the material to be processed. This should also be within the scope of the present invention.
  • a device R 1 has a housing 1, in which only indicated crankshafts 2.1 to 2.4 store a plurality of conveying elements 3.1, 3.2, in particular conveying strips 4.1 to 4.12.
  • the special feature of the present invention is that the conveyor elements 3.1 are arranged above the conveyor elements 3.2, in particular that the conveyor strips 4.1 to 4.6 are arranged above the conveyor strips 4.7 to 4.12.
  • the conveyor bars 4.1 to 4.6, which are driven by the crankshafts 2.1 and 2.2, are arranged above the crankshafts 2.3, 2.4 for the conveyor bars 4.7 to 4.12.
  • the conveying elements 3.1 are preferably approximately congruent above the funding elements 3.2.
  • crankshafts 2.1 to 2.4 can be operated via a common drive can be driven synchronously. Is too conceivable, the crankshafts 2.1, 2.2 and also 2.3, 2.4 assign a separate drive.
  • the individual conveyor slats 4.1 to 4.12 are preferred interchangeable elements 5 provided which a plurality of Have passage openings 6, see Figure 2.
  • the elements 5 can od. Like. On the conveyor elements 3.1, 3.2, in particular Conveyor strips 4.1 to 4.12 can be releasably defined, these having differently large passage openings 6 according to the mixture of materials to be separated exhibit.
  • Quick-change fasteners in particular enable one quick replacement or even replacement of individual ones Elements 5.
  • the fraction of any waste to be separated preferably paper is on a conveyor belt 18 den Conveying elements 4.1 to 4.6 supplied.
  • the fraction to be separated is divided into three fractions.
  • a rotating fraction for example a large one, rolls Containers or the like from the conveying elements 3.1 down on a conveyor belt 14.1 and is transported there, if necessary read out manually or processed further.
  • a fine fraction is given by the corresponding Passage openings 6 in the conveyor elements 3.2 to a Conveyor 19 separated and from this transported away and in others not shown Processing facilities such as magnetic separators, Processed non-metal separator or the like.
  • the so-called Mittelgut for example as a de-inken goods and is about a Volume 20.2 transported for further processing.
  • An advantage of the present invention is that a preferably two-stage balistic separator created with a fraction such as paper on several Fractions according to size, density, weight using the conveyor elements arranged one above the other can be separated can.
  • a device R 2 is shown, which is constructed in accordance with FIG. The difference is that the individual conveyor slats 4.1 to 4.6 of the conveyor elements 3.1 are preferably formed in two parts from a first part 10.1 and a second part 10.2. At the end of the first part 10.1, a web 12 adjoins approximately vertically to a base 11 and projects downwards, to which the second part 10.2 of the conveyor strip 4.1 to 4.6 adjoins at an angle.
  • the first part 10.1 is mounted on the crankshaft 2.1 and the second part 10.2 on the crankshaft 2.2.
  • the formation of the web 12 forms a shoulder 13 which forms a so-called cascade.
  • An overhang 15 can be provided in which on the one hand the first part 10.1 of the conveyor bar 4.1 to 4.6 an initial area of the final offset part 10.2 overlaps.
  • Each of the conveyor strips 4.1 is preferred to 4.6 provided with at least one paragraph 13, wherein in each case an overhang 15 is formed.
  • the overhang has 15 in particular the task that the material, which about the overhang 15 falls, in the case of part 10.1 whose edge on the underlying part 10.2 on the Rolls off and rotates when falling or is circulated.
  • This rotation improves mixing, one Loosening of the material to be sorted, in particular the quantities of recyclables. For example, would overhang 15 would be dispensed with, so the individual mixture of materials slide along the web 15 onto the part 10.2, whereby no rotation or loosening to this extent would.
  • both the Funding elements 3.1 and 3.2 with the funding elements can be provided at least one paragraph 13 to the Loosen up the batch. However, it can also affect the paragraphs 13, as shown in Figure 1, are omitted.
