Definitions

  • the invention relates to a screen deck for screening machines, screens or the like.
  • Such a screen deck consists of a supporting structure and screen components detachably arranged thereon, provided with a large number of screen openings, which complement one another to form a continuous separating surface and have the shape of a polygon in plan, the screen components at least in the region of some of their corners on the supporting structure are attached.
  • a known screen deck of the type mentioned is described in German Offenlegungsschrift 26 32 511.
  • the essentially square sieve components are not only fastened to the supporting structure at their four corners, but lie directly on parallel struts forming the supporting structure with opposing longitudinal sides. In doing so, transfer »&' ' - ⁇ the edges of the sieve elements grip these * struts of the supporting structure and. are therefore supported along the entire length of their long side.
  • the known embodiment suffers from the disadvantage that the screen elements cannot have any screen openings in the area of their longitudinal edges resting on the supporting struts, as a result of which the effective, open screen area is limited.
  • the struts of the supporting structure must be adapted to the support sides of the screen components both in their course and in their dimensions.
  • a predetermined width of the support struts of the support structure cannot therefore be undershot, as a result of which, in the known design, the material expenditure for the support structure cannot be further reduced.
  • the invention is based on the object of a larger, effectively effective, open one
  • OMPI Sieve decks consists in the fact that the support of the sieve components only in the area of their corners enables an enlargement of the effectively effective open sieve surface by the sieve openings being able to reach the edge of the individual sieve components or even beyond.
  • the support structure which is spaced downwards from the underside of the sieve components, does not impede the passage of the sieve material even in the area of those sieve openings which, viewed in the direction of fall of the sieve material, lie above the individual struts of the support structure.
  • the struts of the supporting structure can have a streamlined shape on their upper side and / or can be provided with a wear protection layer.
  • the spacer elements can either be fixedly attached to the screen components or can be designed as separate components which can be inserted between the screen components and the supporting structure. It is also possible to arrange the spacer elements firmly on the supporting structure.
  • the spacer elements can advantageously be formed by support blocks on the supporting structure.
  • the aerodynamic shape of the struts of the support structure on its upper side can be formed by inclined or convexly curved upper sides of these struts.
  • the tops of the struts of the supporting structure be gabled.
  • a further advantageous embodiment of a screen deck according to the invention consists in that adjacent screen components with their adjoining corners are each supported on a single spacer element.
  • the spacer elements expediently have a single receiving opening on their upper side for central fastening of all adjacent corners of the relevant sieve components.
  • the sieve components are advantageously fixed directly in the receiving openings of the spacer elements by means of lugs on the corner and / or by means of locking pins.
  • the screen components consist of elastic solid material with fully or partially embedded reinforcement. Another advantage is if the
  • Sieve components have circumferential diips on the side abutting surfaces.
  • 1 is a top view of a sieve component with spacer elements and indicated support structure for a sieve deck according to the invention
  • 2 shows a section through the sieve component along the line AA in FIG. 1
  • FIG. 3 shows a section through the corner fastening of adjoining sieve components of a sieve deck according to the invention with spacer elements worked onto the sieve components
  • FIG. 4 shows a section along the line
  • Fig. 5 shows a section through another
  • FIG. 6 shows a section through a further embodiment of a corner fastening of the

  • FIG. 8 shows a partial section through the edge of a sieve component for a sieve deck according to the invention
  • FIG. 9 shows the top view of a further screen component for a screen deck according to the invention with embedded reinforcement and Fig. 10 is a top view of another
  • Sieve component for a sieve deck according to the invention with embedded reinforcement.
  • Figures 1 and 2 show the basic structure of a screen deck according to the invention. It is essentially formed by strainer elements 1 • that er ⁇ complement each other to form a continuous separating surface. For this purpose, the individual sieve components 1 abut each other in a spaced-apart arrangement, which is sufficiently known and is therefore not shown in the drawing.
  • Each individual sieve element has the basic shape of a regular polygon and, in a preferred embodiment, the shape of a square, as shown in the drawing. It is important here that not only the fastening but also the support of the individual sieve components takes place only in the area of the corners of the respective polygon, that is to say in the area of the four corners with a square basic shape. If the sieve components have a larger number of corners, the support of the individual sieve components can also be provided only at some of these corners. It is thus possible to attach and support a hexagonal or octagonal sieve component only in the area of every second corner.
  • the screen openings 4 have the same basic shape as the screen component 1 itself, but they can also have a different shape, in particular a slot or slot shape.
  • the sieve components 1 have lugs 6 on the underside, which project downward over the lower boundary surface of the sieve components 1. With these undersides 6 on the underside, the screen components 1 are fastened to an underlying support structure 7, the screen components 1 being connected to the support structure 7 " via spacer elements 8. These spacer elements 8 provide a distance" A "between the base bottom side of the sieve components 1 and the top of the support structure 7. The sieve components 1 can also be attached to the spacer elements 8 differently than via the lugs 6. In the embodiment according to FIGS Bearing blocks 9 are placed as spacer elements 8 in the area of the adjoining corners 5 of the sieve components 1.
  • bearing blocks 9 have on their upper side one or more receiving openings 10 into which the undersides 6 of the sieve components 1 are inserted and fixed therein
  • all approaches are effective 6 in the area of the abutting corners of adjacent sieve components 1 in a common receiving opening 10 of the spacer elements 8.
  • the lugs 6 of the sieve components 1 have the shape of a
  • the struts of the support structure 7 can also be arranged diagonally to the sieve components 1.
  • FIGS. 3 and 4 show sieve components 1 for a sieve deck according to the invention, onto which the spacer elements 8 on the underside are molded directly in the form of protruding spacer feet 11.
  • the height of the spacer feet 11 determines the distance "A" between the underside of the screen components 1 and the top of the support structure 7 of the screen deck.
  • the punching feet 11 are designed as quarter-pipe sleeves and have spreading tabs 12 at their lower end, with which they are inserted through fastening openings 15 on the upper side of the relevant struts of the supporting structure 7 are.
  • FIG. 5 shows a further embodiment of a screen deck according to the invention, in which the screen components 1 are connected to the supporting structure 7 via spacer elements 8 designed as separate components 16.
  • the sieve components 1 can be fastened to the spacer components 16 by means of the projections 6 on the corner, which protrude downward, in the same way as the securing of the sieve components 1 with firmly formed spacer elements 8 according to FIG. 3.
  • the lugs themselves form the spreading tabs 12 with their free ends and receive the fastening pin 13 in the through opening formed by the addition.
  • the separate spacer components 16 have a corresponding receiving opening 17 on the top, through which the lugs 6 of the sieve components 1 are inserted
  • the spacer components 16 can be fastened to the supporting structure 7 below them by means of latching heads 18 formed on the underside, which are buttoned into corresponding fastening openings 19 of the supporting structure 7.
  • the spacer components 16 expediently consist of an elastic material, such as in particular plastic which are preferably also made of the sieve components 1.
  • the mounting pins 13 can be made of the same plastic material.
  • the height of the spacer components 16 determines the essential distance "A" of the underside of the sieve components 1 from the top of the supporting structure 7.
  • FIG. 6 shows one
  • FIG. 7 shows further cross-sectional shapes for the struts of the supporting structure 7, with which these advantages are achieved.
  • FIG. 7a again shows the square cross-sectional profile for the struts 20 with top surfaces 21 which are slanted in the form of a gable roof.
  • FIG. 7b also shows a strut 22 with top surfaces 21 which are slanted in the shape of a gable roof, but this is achieved here by the fact that a resting flat square profile a Winkelsch 'is placed on the upper side iene.
  • 7c shows a strut 23, which has a cylindrical tubular cross-sectional profile with a curved upper side 24. In the same way, the strut 25 shown in FIG.
  • the screen components 1 are only point-supported at their corners, there is a risk that free gaps will form between the side abutting surfaces 26 of the screen components 1 adjoining one another, through which screenings can pass.
  • the sieve components 1 can have at least one circumferential sealing lip 27 along their lateral abutting surfaces 26, which is shown in FIG. 8.
  • FIG. 9 shows a sieve component as is preferably used for a sieve deck of the type according to the invention. It consists of an elastic solid material that is stiffened by an embedded reinforcement 28, 29. The reinforcement is divided into an outer circumferential ring reinforcement 28 located in the area of the edge webs 2, which essentially extends between the support corners 5 of the sieve components 1. Added this reinforcement 28 is reinforced by a cross reinforcement 29 with embedded reinforcement 29 which is arranged in the direction of the transverse and longitudinal center of the sieve components 1. Both the outer reinforcement 28 and the inner, crossing reinforcement 29 can be completely or partially embedded in the elastic solid material of the screen components 1.
  • the sieve components 1 consist of elastic solid material with an outer, annular reinforcement 28, which extends between the support corners 5 of the sieve components 1.
  • the reinforcement 28 is offset somewhat inwards, so that half, outwardly opening sieve openings 30 can be formed along the edges of the sieve components 1, which, as shown in FIG. 10, adjoin the peripheral, half sieve openings 30 Supplement sieve components 1 to full sieve openings. This results in a screen surface with a uniform grid for the screen openings, which extends over all screen components 1.
  • the same effect can also be achieved if the edge webs 2 of the sieve components 1 are made half as wide as the inner webs 3.

Abstract

Le plateau et les bordures ou analogues des cribleuses peuvent etre disposes de facon amovibles sur la structure portante (7). Ils peuvent etre constitues de parties (8) munies d'un grand nombre d'ouvertures de criblage. Ces parties ou elements du crible se completent le long d'une surface de separation traversante. Elles sont fixees a la structure portante uniquement dans la region de certains de leurs angles. Pour obtenir une grande surface de criblage ouverte et de grande efficacite, les parties ne sont pas disposees de facon usuelle avec leurs bords sur la structure portante mais seulement dans la region de leurs angles de fixation, a distance de la structure portante, soutenues par celle-ci et reliees a elle par des entretoises. Ainsi, la surface de criblage active, formee par les ouvertures de criblage, peut-elle s'etendre jusqu'au bord de chaque partie ou meme aller au-dela. La structure portante n'empeche plus le passage de la matiere a cribler.
