Definitions

  • the invention relates to a separating device with which elongated solid parts from other solid parts be separated.
  • Thermal processes are known for waste disposal, at where the waste is burned in waste incineration plants or in Pyrolysis plants pyrolyzed, i.e. in the absence of air Temperature from about 400 ° C to 700 ° C is subjected. at Both methods make sense after the combustion or to separate the residue remaining after pyrolysis, to either recycle it or dispose of it in a suitable manner. The aim is to residual material to be disposed of in a landfill as low as possible to keep.
  • the pyrolysis residue also has non-combustible parts.
  • the non-combustible parts essentially consists of an inert fraction, such as glass, Stones or ceramics, as well as composed of a metal fraction.
  • the valuable materials of the residual material are sorted out and one Recycled. There are procedures for sorting out and components necessary that are reliable and ensure continuous operation.
  • Solid parts of a certain geometry are separated, so that the operation of downstream disconnecting devices for the remaining solid matter, so that it can be separated further.
  • a special The problem is often elongated solid parts, in particular wires or fine stranded wires. The latter are very difficult to separate from the rest of the solid and lead to blockage of sieve holes in sieves. This especially applies when these elongated solid parts are below a certain size.
  • a discharge device is known from WO 97/26495, which a conveyor for the promotion and separation of pyrolysis residues having.
  • the conveyor has a sawtooth profiled partition that is used to promote the Pyrolysis residue is vibrated.
  • the fine proportions of the pyrolysis residue At the A rod screen for separating the separated ones is at the end of the partition fine portions of the remaining coarse portions arranged.
  • This device has the disadvantage that together with the fine proportions also large flat and oblong portions are deposited. Because these can align in longitudinal grooves and through the adjoining Fall through the sieve. An effective separation of fine Wires or similar elongated solid parts not possible.
  • the present invention has for its object a Specify separation device for elongated solid parts, the effective separation of elongated Solid parts as well as a trouble-free and continuous Operation enables.
  • a separating device for elongated solid parts that one Vibrating floor with a number extending in the conveying direction Has longitudinal grooves to which screen openings connect to separate the elongated solid parts, the groove depth of the longitudinal grooves in the conveying direction decreases.
  • the side walls are to allow to the swinging floor the longitudinal grooves are preferably formed obliquely.
  • a wavy Profile or a sawtooth profile For a simple and reliable alignment of the elongated solid parts in the conveying direction of the Swinging floor in an advantageous embodiment a wavy Profile or a sawtooth profile.
  • the Sieve openings up to the end of the in the conveying direction Separator are therefore open towards the end. This is an essential feature to ensure that there are no solid particles in the separator accumulate or jam. Because with one example elongated sieve opening with peripheral edge the edge piece in the conveying direction for the solids flow to represent a resistance. This can be solid parts impose, clogging the sieve opening and thus lead to a malfunction of the separator could.
  • the sieve opening preferably widens continuously and in particular V-shaped.
  • edges of the screen openings are elastic are trained. Then the effort is to loosen of possibly stuck solid parts only slightly. at the same time is thereby the of jammed solid parts exerted load on the separator in comparison reduced to inelastic edges.
  • the flare is formed by the rag in this training.
  • the separation device is in a preferred embodiment a cleaning rake with a number of tines provided which can be inserted into the sieve openings and into the Sieve openings are movable in the conveying direction.
  • the cleaning rake can Depending on requirements, periodically or continuously in the sieve openings be moved. For loosening jammed Solid parts with the cleaning rake is the widening of the screen openings is of great advantage because of the cleaning rake the jammed solid parts just a little bit in Direction of conveyance must move until they have come loose and fall through the widened sieve opening. To the burden of Keeping cleaning rules as low as possible is also the elastic formation of the edges is particularly advantageous.
  • the vibrating floor is for a robust design made of metal.
  • FIG. 1 it extends in a separating device 1 a metallic vibrating floor 2 from a task area 4 for solid F (e.g. pyrolysis residue from a pyrolysis plant) in conveying direction 6 to a separation area 8.
  • a metallic vibrating floor 2 from a task area 4 for solid F (e.g. pyrolysis residue from a pyrolysis plant) in conveying direction 6 to a separation area 8.
  • V-shaped elongated sieve openings 10 of which only two are shown.
  • screen openings 10 each one of one Number of parallel longitudinal grooves 12 of the vibrating base 2, of which only two are also shown.
  • the sieve openings 10 accordingly close to the longitudinal grooves in the conveying direction 6 12 and expand from there to End 14 of the separator 1 continuously.
  • the Groove depth of the longitudinal grooves 12 increases towards the screen openings 10 down. This is from a comparison of Figures 2 and 4 as well of Figures 3 and 5 can be seen.
  • the two lateral edges of the respective screen opening 10 are elastic, especially as tapered elastic Rag 16, formed.
  • the lobes 16 are approximately triangular formed so that the V-shaped shape of the sieve openings 10th is formed by the two attached tabs 16.
  • the solid F is in the application area 4 on the vibrating floor 2 abandoned. Because of the vibrations of the vibrating floor 2 (by means of a vibration device, not shown) the solid F is transported in the conveying direction 6.
  • the Vibrations of the vibrating floor 2 also cause that elongated solid parts 18, e.g. Pieces of wire, from which one is shown in Figure 1, in the longitudinal grooves 12 in Align conveying direction 6.
  • the vibrating floor 2 therefore causes a promotion of the solid F and at the same time an orientation of the elongated solid parts 18. The vibrations become generated for example with the aid of an eccentric drive.
  • the groove depth is dimensioned so that the once aligned elongated solid parts 18 in the conveying direction 6 aligned to continue.
  • the Schwing founded 2 can therefore in the area immediately in front of the screen openings 10 be almost flat or even.
  • the waning Groove depth flat solid parts 20 one of which is shown in Figure 1, flat and substantially parallel aligned to the swinging floor level. Laying flat flat solid parts 20 is by the vibrating or Swinging movement of the swing base 2 is supported.
  • the aligned elongated solid parts 18 fail through the elongated sieve opening 10 and are thus of the remaining solid F is deposited.
  • Be opposed flat solid parts 20 initially also from the Longitudinal grooves 12 aligned, but then laid flat so that it through the screen openings 10 to the end 14 of the separator slide. You will only be deposited here.
  • FIG 1 is also in each of the two sieve openings 10 a prong 22 of a cleaning rake 24 (cf. Figure 6) shown.
  • the tines 22 are close in range of the longitudinal grooves 12 inserted into the screen openings 10 from below and guided along in the conveying direction 6. there push a possibly stuck solid part 26 in the conveying direction 6 so that it is released and then due to the widening of the sieve opening 10 through it falls through. Because of the elastic formation of the edges the sieve openings 10 can only be a solid part 26 clamp a relatively small force, so that the stress the prongs 22 and the cleaning rake 24 small is.
  • Figures 2 and 3 each show a section through the vibrating floor 2 in the task area 4 along the line II-II or III-III in Figure 1.
  • the vibrating floor 2 a sawtooth-like profile with V-shaped grooves, the longitudinal grooves 12, on.
  • the vibrating floor 2 has in contrast a wavy profile.
  • the sawtooth-like profile is for alignment of elongated solid parts 18 is an advantage.
  • Figure 4 and Figure 5 show the sawtooth and the wave-shaped Profile in section along the line IV-IV or V-V through the sieve tray 2, immediately before the sieve openings 10 begin. It can be seen that here the Longitudinal grooves 12 have a significantly smaller groove depth. While the oblique side walls 28 of the longitudinal grooves 12 2 and 3 are still very steep, they run according to Figure 4 and 5 very flat. The flat solid part 20 is therefore lay flat over the longitudinal groove 12, which in Figure 4 is shown.
  • the side walls 28 are in the area of the screen openings 10 Sieve walls 29 continued. At the edges are the elastic Tab 16 attached, as can be seen in Figure 6 is.
  • the sieve walls 29 can both be flat, and - as shown - form a profile. In the sieve openings 10 engage the prongs 22 of the cleaning rake 24 on.
  • the cleaning rake 24 is, for example, in a Rail 30 out.
