Definitions

  • the invention relates to a circular construction device for classifying or Sorting goods, also called screening machines, especially one Tumbler screening machine.
  • screening machines also called screening machines, especially one Tumbler screening machine.
  • Such a screening machine is for example became known from the prospectus "tumble screening machines” of the applicant from April 1998.
  • "Classification” is a separation by grain size understood and under “sorting” a separation by substance types.
  • the invention is basically applicable to both types of procedure. The simplicity for the sake of convenience, however, only the term “classifying” should be used in the following.
  • Devices of this type are used in very many branches of industry.
  • the food industry and the chipboard industry are just examples called the chemical industry.
  • the devices are used for Disassembly of a flowable or pourable material into solid or liquid Form, for example in the form of a suspension, in individual components.
  • On possible purpose of such a device is, for example, a granular material in different fractions of different grain sizes disassemble.
  • Another application is the separation of Impurities from a good.
  • a device of the type mentioned includes a housing, further at least one classifying screen, at least one inlet for the classifying Well, at least one outlet for the accept and at least one outlet for the backlog.
  • a good is to be broken down into two or more fractions, one needs a screening machine with a corresponding number of screening decks. These are generally arranged one above the other. The good will be there first abandoned on the upper deck. This creates a first Fraction, which through a first Gutstoffauslass from the housing of the Screening machine is removed. This first fraction has relatively large ones Particles on. The remaining good that has been screened for the first time, that by has passed through the first sieve body, then passes to a second Screen deck. Here is a second fraction with particles of somewhat smaller size severed. The individual screen decks are arranged one above the other. The Screening machine therefore has a certain vertical extension, the one appropriate room height of the company building is required. This is not always available.
  • the invention has for its object to provide a screening machine requires a smaller installation space upwards than was previously the case.
  • the inventor has accordingly recognized that the classification process involves disassembly of a good in several fractions can also be carried out in that divided a sieve body into a number of ring segments, the individual ring segments differing classification properties to have. This makes it possible to have one on a limited number of decks perform multi-stage classification process in which two or more Fractions.
  • the screening machine shown in Figure 1 has a housing 1 This is from essentially cylindrical shape.
  • the housing 1 encloses a single one Screen deck 2.1.
  • This comprises a sieve body.
  • the sieve body is like this divided that an inner ring segment 2.1.1 and an outer ring segment 2.1.2 arises.
  • a perforated plate 2.2 is located below the screen deck 2.1. On the Perforated sheet lie balls 2.2.3.
  • the machine makes a wobbling or gyratory movement. This causes the material to be screened to move on the screen body. she causes the balls 2.2.3 which are on the Perforated plate 2.2 lie against the sieve body of the sieve deck 2.1 from below, and thus a loosening of particles that are in the mesh of the Screen body stick.
  • the two ring segments of the screen body have different ones Classifying properties.
  • the inner ring segment 2.1.1 the screen body 2.1 has a mesh size of 1.6 mm while the outer Ring segment has a mesh size of 2.2 mm.
  • FIG. 1 there is a screen 2.1 cylindrical nozzle 1.2. This separates the inner ring segment 2.1.1 from the outer ring segment 2.1.2.
  • An upper outlet 1.3 can also be seen, a middle outlet 1.4 and a lower outlet 1.5.
  • the mentioned nozzle 1.2 has an opening through a flap 1.2.1 is lockable. You can see how this flap looks in plan view - at a similar embodiment of a screening machine according to the invention - from Figure 2b.
  • the device works as follows:
  • Material to be screened is introduced into the nozzle 1.2 from above. It arrives on the inner segment 2.1.1 of the screen body 2.1. Particles with a Diameters of up to 1.6 mm fall through and reach the outlet 1.5. Larger particles, on the other hand, migrate outwards against the inner edge of the nozzle 1.2. You get through the opening with the flap 1.2.1 finally on the outer ring segment 2.1.2. Those particles that one have larger diameters than 2.2 mm through the outlet 1.3. Particles emerge from outlet 1.4, which have a diameter of between 1.6 and 2.2 mm.
  • Figures 2a, 2b and 3 leave details of another embodiment detect.
  • On the perforated plate also called “baffle plate”, for example Balls arranged. These knock from below when the device is working against the sieve body and thus help to keep the sieve openings free at.
  • the flap 1.2.1 already mentioned can be controlled in the present case, so that the selectivity can be influenced.
  • Stall of two sieve segments can also be a sieve body in three or more Sieve segments are divided.
  • FIGS 4 and 5 illustrate a tumbler screen in which a single screen deck has three ring segments 2.1.1, 2.1.2 and 2.1.3.
  • the Ring segments are in turn divided by cylindrical partitions. You can also see flaps 1.2.1, 1.2.2 and 1.2.3.
  • the material to be classified is placed on the central screen 2.1.1 given up.
  • This central screen disc has a fine mesh size. in the In the course of the tumbling movement, the fine components fall through the mesh through it. The coarser migrate through the opening in the flap 1.2.1 to Ring segment 2.1.2, which has an average mesh size. What on that Ring segment 2.1.2 remains, passes through the opening in the flap 1.2.2 to the outer ring segment 2.1.3.
  • the embodiment shown in Figure 6 again has a subdivided Sieve deck on. It comprises a central, central, circular sieve disc 10.1.1 fine mesh size.
  • This central screen disk 10.1.1 is surrounded from a cylindrical partition 10.2.
  • a screen deck according to the invention can thus be in closed ring segments can be divided. But it can also do that individual ring segment can be subdivided again, as with the Embodiment according to FIG. 6.
  • a very decisive advantage of the invention is in any case the following: It is not necessary to stack several screen decks one above the other. Hereby the tipping forces are kept to a minimum. In addition, there are rough ones Impurities are often present only in small quantities. In the state of the art must still have a complete screen deck for these coarse contaminants be used. Applying the invention, everything can be combined in one run single screen deck, or at least the number of Limit sieve decks.
