Definitions

  • the invention relates to a sieve element, in particular sieve discs of disc sieves and a disc screen with a number of mutually parallel rotatable axes for separating supplied material, in particular for separating bulk materials, such as compost, bark mulch, rubble and the like organic or inorganic materials.
  • Various screen systems are known in the prior art, which are used for the presorting of bulk materials, in particular recyclable or reprocessed bulk materials application.
  • Such a screen system also referred to as a screen screen, is for example in DE 93 09 872 U1 as well as in the EP 1 088 599 B1 described.
  • Such screening systems have parallel waves to be driven synchronously or asynchronously, the groups of sieve elements, such as screen stars, which are axially offset relative to the gap, are provided.
  • Such screen stars are usually made of elastic material and have elastically yielding sickle-shaped, extending in the radial direction to the shaft fingers or star fingers. The fingers are aligned in the direction of rotation nacheilend and are accordingly designed as Abstreifzinken. The respective distances between adjacent, rotatably mounted screen stars and Siebsternwalzen are to be sorted each good.
  • the EP 1 088 599 B1 describes rotary screen elements, which have reinforcing parts on selected star fingers, which constantly travel during the screening process over the collar of adjacent rotary screen elements which is axially widened in relation to the star fingers.
  • the cleaning elements are designed such that they almost completely fill the space between the star discs, so that in these star disc gaps the sorted to be sorted with the Sternusionnsieb Good and can be squeezed, which increases the mechanical stress on the screen significantly.
  • a generic sieve is from the AU 259 866 A known.
  • the sieve element has crescent-shaped star fingers, which are arranged distributed around the axis of rotation of the sieve element.
  • the outer contour of the screen element is in one Projection formed perpendicular to the axis of rotation eccentric to the axis of rotation.
  • a similar sieve element is also from the US 2,150,717A known.
  • Another sieve is from the FR 1 240 250 A known.
  • This sieve element has an outer contour which is arranged concentrically to the axis of rotation of the sieve element.
  • a reinforcing element is provided on a star finger, which projects beyond the end of the star finger to the outside.
  • Another turn screen element is from the WO 94/20227 A1 known.
  • the present invention is therefore an object of the invention to provide novel and improved screening elements, as well as an improved disc screen available, in which lower mechanical stresses on the screen elements occur and which is less prone to foil, fiber or rope-like objects in the to capture separating bulk material.
  • a higher screening performance and an adaptability to already existing Scheibensiebsysteme available are also provided.
  • the screening element according to the invention is intended for use in a disc screen having a number of parallel rotatable shafts or shafts. On these axes, individual sieve elements are arranged so as to be non-rotatable with respect to one another in a gap, so that sieve elements of adjacent shafts intermesh with one another during rotation operation.
  • the screen element may have a polygonal, elliptical but also polygonal, such as four-, six- or octagonal outer contour, wherein radially outwardly extending portions of the screen element immersed in axial interstices of screen elements adjacent arranged waves.
  • the sieve element according to the invention is characterized in that it is formed or mounted in the plane perpendicular to the axis of rotation eccentric to the axis of rotation, so that during operation of the Scheibensiebs, ie upon rotation of the sieve around its axis of rotation, the sieve size of the Scheibensiebs.
  • the screen hole size here is to be understood as the radial distance between an outer contour section of a screen element to the hub or to the collar of one or more screen elements mounted on an adjacent axle or shaft.
  • An eccentric design or arrangement in the sense of the invention means an asymmetrical geometry or off-center mounting of the sieve element with respect to the axis of rotation.
  • the required eccentricity of the Siebelements can in different ways, such as by an off-center or eccentric storage of Siebelements and / or be achieved by a correspondingly asymmetrical geometric design, in particular the outer contour of the screen element.
  • the eccentric training or storage is universally applicable to a variety of different screen elements, in particular on screen plates with different outer contours.
  • star-shaped disks provided with sickle-shaped star fingers are like four-, six-, eight- or the like polygonal contours of screen disks as well as polygonal, elliptical or rounded toothings, outer contours of screen disks within the scope of the invention.
  • edges or end sections of a screen element which lie in the radial direction outside are spaced apart from the axis of rotation of the screen element differently from the axis of rotation.
  • the individual outer end sections may themselves have a different extent in the radial direction.
  • an asymmetry or a corresponding eccentricity can also be provided between the axially widened collar and the projection of a region of the sieve element forming the outer contour.
  • the outer contour of the sieve element has a plurality of sickle-like radial fingers extending in the radial direction, so that the sieve element is designed as a so-called star body or star disc.
  • the free ends of the star fingers are spaced differently far from the axis of rotation of the star body, resulting in a rotational symmetry deviating outer contour of the star body or the Siebelements with respect to its suspension or storage on the rotatable axis.
  • the radially outer end portions of adjacent star fingers in the circumferential direction of the star body have a continuously changing distance from the axis of rotation.
  • the throats provided between the individual star fingers can come to lie far different from the widened collar of the star body.
  • such a throat or the associated star finger approach coincides with the axially widened collar of the star body.
  • the radially outer end portions of the individual star fingers lie on an imaginary circle whose center is radially offset from the axis of rotation of the star body.
  • the star body has a radially symmetrical outer contour. Only through its eccentric bearing on the axis of rotation does it perform a tumbling motion during operation of the star wheel screen, which has a loosening and throughput-promoting effect on the screenings.
  • a cleaning element is arranged on at least the radially outer portion of the screen element whose free end has the greatest radial distance from the axis of rotation.
  • This, also as reinforcing part trainees cleaning element has typically has a greater rigidity than the screen element, which is preferably made of elastic material, such as synthetic or natural rubber.
  • the preferably made of steel, plastic or a ceramic material cleaning element is arranged on the outer contour of the sieve or on a star finger, so that it can almost completely fill the space between two radially and axially staggered screen elements of an adjacent wave and free from deposits.
  • the mechanical stresses occurring due to the cleaning can be reduced to a minimum, in particular without significantly reducing the cleaning effect, which has a positive effect on the energy consumption of the entire screening device.
  • the wear of the sieve elements as well as the cleaning elements to be provided on the sieve elements can be advantageously minimized in an advantageous manner.
  • the cleaning element projects radially outward from an associated star finger.
  • the individual star fingers do not directly approach the hub or the collar of star bodies of adjacent axes of rotation. This interstice not filled by the intermeshing star fingers is ultimately filled by the cleaning element and freed by this dirt and deposits adhering there.
  • the cleaning element is wider in the axial direction than the associated star finger.
  • the cleaning element is thus at least partially in an axial direction, but preferably on both sides in the axial direction on the associated star finger, so that by means of the cleaning element of the axial gap between star fingers of star bodies of an adjacent shaft or axis of rotation can be almost completely filled by the cleaning element.
  • the cleaning element comes to lie completely within the radial extent of the associated star finger or an associated outer region of the outer contour of the screen element.
  • the cleaning element does not over the radial outer edge of an associated star finger over. Nonetheless, scraping or cleaning along the free end section of the star finger on the adjoining waistband takes place due to the stiffening action of the cleaning element.
  • the non-radial protrusion of the cleaning element and the eccentric storage of Siebelements have an advantageous effect on the film and Seilfangeigenschaften the Scheibensiebs, since langfädige or fibrous materials such as wires, fibers, carpet residues, films or the like straight through the continuously changing Sieblochaise and not radially protruding cleaning fingers are less trapped during sieving.
  • the invention relates to a disc screen with a number of mutually parallel rotatable axes or shafts on which individual sieve elements, in particular star discs are arranged.
  • individual sieve elements in particular star discs are arranged.
  • the previously described eccentrically formed or eccentrically mounted sieve elements are provided on at least one axis of the disc screen.
  • Such a screen in which sieve elements of a rotatable shaft perform a tumbling motion corresponding to their eccentricity, has a higher screening capacity than conventional screen systems known from the prior art, since the screen hole size continuously changes during operation of the screen screen and by the tumbling movement , In particular perpendicular to the plane of the axes of rotation, a vertical stroke is exerted on the screenings. This learns by a loosening, which also has an advantageous effect on the screening performance and throughput of the disc screen.
  • a particular advantage of the invention results from the fact that already existing star screen with consistently concentric sieve elements or star discs with the invention eccentrically or eccentrically to be stored screen elements or star discs retrofitted or can be converted.
  • the eccentric mounting of a sieve element according to the invention can also be produced in a particularly simple and cost-saving manner by an eccentricity is generated by concentrically formed sieve elements in a central recess which is provided in particular for storage on a rotary shaft or axis by adding a compensating body ,
  • axes are provided with concentric sieve elements, in particular star discs.
  • it is provided to provide adjacent axes or waves alternately with eccentric sieve elements according to the invention and with conventional, that is to say concentrically designed sieve elements.
  • the distance between adjacent axes of the disk screen or the diameter of the screen elements is selected such that one star finger or radially outer region of an eccentrically formed screen element or a star disk whose radially outer end section has the greatest radial distance from the axis of rotation , in at least one position of the axis up to the collar or the hub of one or more sieve elements or star body of an adjacent axis extends, so that in the position in which the said star finger substantially comes to rest on an imaginary connecting line between adjacent axes of rotation with its cleaning element provided on the adjacent hub or collar scraping along.
  • a cleaning effect is achieved in particular by the fact that adjacent rotary axes equipped with sieve elements rotate at different speeds, so that the outer area equipped with the cleaning element always reaches at least almost at each revolution at different positions of the outer circumference of the hub or the collar of the adjacent sieve element or along there scrapes.
  • the eccentrically formed or eccentrically mounted sieve elements of a common rotatable axis are arranged rotated in the circumferential direction to each other. Consequently, such adjacent in the axial direction coming eccentric sieve elements of an axis are not formed with the same, but with mutually offset eccentricity or are correspondingly rotated but rotationally fixed to the respective shaft.
  • the sieve elements arranged adjacent to one another in the axial direction on a common axis of rotation are each arranged rotated by 90 ° or by 180 ° relative to one another.
  • Such a 90 ° or 180 ° offset causes a ⁇ / 2 or n phase-shifted vertical stroke on adjacent star bodies.
  • FIG. 1 Sieve element 10 shown in plan view, which is designed as a sieve star or star body of a star disk, has an eccentric geometry with respect to its axis of rotation 15 or an eccentric outer contour, which is formed by the radially outer end regions of the individual star fingers 16, 24, 26.
  • a square recess 12 is provided, with which the star body can be non-rotatably pushed onto a (not explicitly shown) shaft of a star wheel screen and attached thereto.

  • the individual crescent-shaped star fingers 16, 24, 26 aligned in the direction of rotation A are distributed uniformly over the circumference of the star body 10. Only the finger 24, whose free end has the largest radial distance 30 to the axis of rotation 15, differs slightly in its outer contour of the remaining fingers 16, 26.
  • the trailing throat 20 of this finger 24 is closed in a slightly greater degree than the remaining grooves 18 located between the fingers 16, 26, so that this finger 24, which is provided with a cleaning element 22 has a slightly greater rigidity compared to the other fingers.
  • FIG. 4 In the perspective view to be recognized collar 14, which is slightly widened in the axial direction relative to the fingers 16, 24, 26, points in the in the FIGS. 1 to 4 illustrated embodiments, a concentric and thus rotationally symmetrical with respect to the rotation axis 15 training.
  • the grooves 18 formed between the individual fingers 16, 24, 26 have different radial distances from the collar 14 over the circumference of the star body 10. While the throat trailing the finger 26 substantially coincides with the collar 14, the grooves 18 trailing the fingers 16 or 24 are spaced radially from the collar 14.
  • the cleaning element 22 designed as a reinforcing part is arranged on that cleaning finger 24, which comes to lie furthest away from the axis of rotation 15, so that a cleaning and consc matters adjacent star bodies 100, 200, as for example in the Figures 2 and 3 are shown, only temporarily during the passage of the cleaning element 22 by the imaginary line connecting the axes of rotation adjacently arranged star body 10, 100, 200 takes place.
  • the adjacent adjacent to the eccentrically shaped star wheel 10 arranged further star discs 100, 200 are in the embodiments shown here is substantially concentric, ie radially symmetrical. These have, in the same way as the star disk 10, in each case a through opening 112, 212 and in each case a cleaning element 122, 222 provided on a cleaning finger 124, 224.
  • Cleaning elements 22, 122, 222 do not protrude over the associated star fingers 24, 124, 224 in the radial direction, but protrude above this primarily in the axial direction, so that in the meshing movement of star fingers adjacent star disk 10, 100, 200 of the larger axial deflection of the respective collar 14, 114, 214 formed opposite the fingers gap can be almost completely filled and cleaned by the cleaning element 22, 122, 222.
  • substantially concentric formation of the collar 14, 114, 214 of each Star body 10, 100, 200 allows that not only the collar 114, 214 of the star discs 100, 200 is cleaned by the cleaning element 22 of the eccentric star disk body, but that, conversely, the eccentrically shaped star body 10 centrally formed collar 14 of the cleaning elements 122 and 222 of the adjacent star discs 100, 200 can be reliably removed from deposits.
