Definitions

  • the invention relates to screening apparatus, particularly for sizing and/or deliquefying particulate materials, such as aggregates, and is especially, but not exclusively, applicable to screening apparatus having a flat or cambered sieve screen surface.
  • a sieve screen comprising a plurality of rectangular metal sieve elements supported on a frame of elastic, rubber or plastics material surrounding the elements is known from "Har-particularlyungs-technik" Volume 11 No. 7 published in July 1970 pages 403-405.
  • An object of the present invention is to provide screening apparatus for sizing and/or deliquefying aggregates which allows realisation of advantages of both synthetic plastics and traditional metal screening media.
  • a sieve screen for sizing and/or deliquefying aggregates comprising a plurality of apertured metal sieve elements and attachment means of synthetic plastics or natural or rubber synthetic cooperating with edge portions of each sieve element to secure the elements together and/'or to an underlying support structure, characterized in that the attachment means comprises a collar for each element and completely surrounding the element.
  • the sieve screen may comprise a plurality of similar modules, each comprising at least one said apertured metal sieve elements and associated synthetic plastics attachment means.
  • the metal sieve element may be secured to the attachment means by way of metal flanges, tongues or other protrusions projecting from the periphery of the element, conveniently to a groove or slots in the attachment means.
  • the flange or tongue members extend in a plane which is substantially parallel to the screening surface.
  • the flange or tongue member may then conveniently comprise one flange of a member of "L" shaped cross-section, the otherflange being secured to the apertured portion of the metal sieve element.
  • the metal flange or tongue members may project downwardly from the periphery of the sieve element, i.e. away from that surface of the element which will be uppermost in use.
  • the lower part of the or each depending flange or tongue may be lipped, curved, beaded or otherwise formed to positively engage the slot or groove so as to resist removal therefrom.
  • each sieve element comprises a plurality of wires, typically of wedge-section, secured side-by-side by transverse ribs.
  • Flanges or tongue members which extend in the direction of the ribs are secured to the ends of the wires, for example by welding, similar members extending parallel to the wires may then be secured to the ends of the transverse ribs or/and to the endmost wire adjacent that edge of the element.
  • the flange members extend continuously along each side of the element.
  • the element is of cornered shape, for example rectangular, with one or more flanged members secured to each side thereof, adjacent flanged members may also be secured together at the corner.
  • the flanged member comprises a continuous ring around the element.
  • the attachment means may extend releasably around the entire periphery of the metal sieve element and have depending formations to engage the support structure, for example lugs to engage a lipped groove in the support frame.
  • the attachment means may be formed as a unitary member, or from a plurality of separate parts, for example two L-shaped parts which, fitted onto the edges of the element, form a complete collar. Such a plurality of separate parts may be separable from the metal sieve element, their engagement with the support structure and/or adjacent modules when installed, being arranged to maintain, even enhance, their interfitment with the elements.
  • the attachment means may be moulded directly onto the edges, e.g. flanges, of the metal sieve element, especially where the metal sieve element is made of apertured plate or wire mesh. Where the sieve element is of looped or welded wedge wire or the like, however, such direct moulding may require steps to be taken to limit penetration of the sieve apertures by the plastics material, for example by providing removable inserts in the apertures adjacent the edges of the sieve element during moulding.
  • the sieve elements may comprise looped wedge wires secured together by tie rods, any of the various known rod end fitments being employed, such as nuts on threaded tie rods or rivetted ferrules. Then, instead of a peripheral flange being provided, the ends of the tie rods may project beyond the edge of the metal sieve element and locate in recesses in opposed side parts of the attachment means. The endmost aligned loops of the element then preferably seat in grooves in the other opposed side parts of the attachment means.
  • the cross-section of at least a medial part of each groove is such as to retain the respective loops therein.
  • the aforesaid support structure of the screening apparatus may comprise a plurality of parallel support bars, the metal sieve elements being supported above and between the bars by the associated attachment means cooperating with a grid or lattice-like support frame of metal and/or synthetic plastics material, conveniently supported by the support bars, which preferably are aligned with cross-members of the lattice-work frame.
  • a screening machine has a plurality of screen modules 10 assembled edge-to-edge to form a screening surface 12.
  • the modules 10 are secured to an underlying support frame in the form of a square lattice or grid 14.
  • Each modules obscures one hole 16 of the lattice, which is itself supported by support bars 18, of inverted "L" section, which extend longitudinally of the bed of the machine and coincide with the cross-members of the lattice 14.
  • the support bars 18 are carried by beams 20 which extend across the bed of the machine. If desired the heights of the support bars 18 may increase towards the middle of the machine to camber the screening surface.
  • a wedge-shaped polyurethane wear strip 22 is provided between the machine side plates 24 and the adjacent screen modules so as to present an inclinded surface 25 to divert aggregate inwardly to the screening surface.
  • each screen module 10 comprises a metal sieve element 26 made up of a plurality of looped wedge-section wires 28 secured side-by-side, the loops being thicker or "joggled” in known manner to define sieve apertures between the wires.
  • Threaded tie rods 30 extend through aligned loops of the wires 28, which are clamped together by nuts 32 screwed onto opposite ends of the tie rods.
  • Alternative end fitments, such as ferrules, might be employed.
  • the sieve element 26 fits into a rectangular attachment collar 34 of synthetic plastics material, such as polyurethane.
  • a square recess 37 equal in size to the wedge wire part of the element so as to accommodate the latter with the upper surface of the wires level with that 36 of the collar 34.
  • Opposite sides 38 and 40 of the attachment collar 34 each have a series of five registering holes 42, immediately beneath the bottom of the recess 37 and spaced apart to accommodate the ends of the tie rods 30 and associated nuts 32. As shown in Figure 3, the holes 42 are stepped at 44, and dimensioned to conform to the tie rods and nuts.
  • the other opposed sides 46 and 48 of the attachment collar 34 have upwardly-opening grooves 50 and 52, respectively, to accommodate the endmost rows 54 and 56 of aligned loops of the wires 28.
  • the grooves 50 and 52 are of circular section and extend around a major portion of each loop to secure together that side of the attachment collar and the sieve element.
  • the tie rods and nuts associated with the endmost aligned loops of wires are also accommodated in holes 42 suitably aligned with the grooves 50.
  • the looped wedge-wire sieve element might be provided with peripheral flange or tongues, extending outwardly or downwardly, to engage in a suitably disposed groove or slots in the attachment collar 34.
  • the flange or tongues might be welded to the wires 28 and/or to the tie rods 30, which might extend through suitably aligned holes in the flange.
  • FIGs 5, 6 and 7 illustrate the screen module 80 of a second embodiment of the invention.
  • the screen module 80 is intended to fit a screening machine having a support frame 14, supports 18 and beams 20 as disclosed in Figure 1.
  • Each screen module 80 shown in Figure 5 differs from those disclosed in Figure 2 in that, instead of a metal sieve element made up of a plurality of looped wedge-section wires the screen module 80 comprises a rectangular metal sieve element 82 made up of a plurality of straight wedge-section wires 84 secured side-by-side by spaced transverse ribs 86 (see Figures 6 and 7) extending across substantially the entire width of the element 82.
  • the ribs 86 are of rectangular cross-section and are secured, conveniently by resistance welding, to the undersides of the wires 84.
  • the edges of the sieve element 82 are bounded by metal flange members 90, 92, 94 and 96, respectively.
  • Each member is of "L" shaped cross-section and has one flange secured to the wire(s) 84 so that its other flange extends outwardly from the element and generally parallel to the uppermost surface thereof.
  • the two flange members 90 and 94 extending across the wires 84 are welded to an endmost one of the transverse ribs 86', (see Figure 6) which is secured to the wires 84 immediately adjacent their ends.
  • the flange members 90 and 94 could be welded directly to some or all of the respective adjacent ends of the wires 84.
  • the other two flange members 92 and 96 extend across, and are welded to some or all of, the opposite ends of the transverse ribs 86. If desired, these flange members may also be secured directly to the wire 84' (see Figure 7) adjacent the ends of the ribs 86.
  • Ends of flange members 90, 92, 94 and 96 are secured, e.g. welded, to each other at the corners of the element to form a continuous ring.
  • the ends of the members 90, 92, 94 and 96 are mitred so that the corners of the assembled element 82 are truncated, as at 97.
  • flange members 90-96 could be attached to a sieve element of a different type e.g. the looped wedge wire type described with reference to Figure 2, or woven mesh, perforated plate or other apertured metal.
  • the sieve element 82 fits into a rectangular attachment collar 98 of synthetic plastics material, for example polyurethane.
  • a square recess 102 equal in length and width to the upper part of the sieve element 82 i.e. as measured across the vertical flanges of members 90-96.
  • the recess 102 opens into a slot 104, extending into the collar and parallel to the plane of the sieve element.
  • the slot 104 is dimensioned to receive, and preferably grip, the outwardly- directed flanges of the element.
  • the projecting flange need not extend along the entire side of the element. It is envisaged that a plurality of discrete flanges or tongues might be provided spaced around the periphery of the element.
  • the slot 104 might still be continuous, although a more robust construction might be achieved where a corresponding plurality of slots were provided, each complementary to the associated one of the discrete flanges or tongues.
  • the sieve elements 110 illustrated in Figure 8 and 9 have downwardly-projecting peripheral flanges 112, each comprising a strip of metal welded to the edge of the element so that its upper edge is level with the upper surface of the element and its lower edge projects below the lower cross-rods 86.
  • the sieve element shown in Figure 8 has only two flanges extending one at each opposite edge of the element and parallel to the wires 84. Each flange is welded to the ends of the cross-rods 86 as at 114. If desired, the inner surface of the metal strip flange could also be welded to the endmost wire.
  • the sieve element shown in Figure 9 is similar to that shown in Figure 8, but has flanges at all four edges of the element.
  • the flanges 116 extending parallel to the cross-rods 86 are welded to the ends of the wires 84 and/or at their ends to the adjacent flanges 110.
  • the downwardly-projecting portion 115 of the flange is intended to fit into a vertical slot in the synthetic plastics attachment means, relying upon the resilience of the material to grip and retain the flange therein.
  • Improved security of the element in the attachment means may be obtained by suitable shaping of the depending portion of the flange, for example by curving it inwardly, as indicated by broken lines in Figure 8, to form a lip 118, which can then underengage a suitable lug of the attachment means.
  • the collar may be moulded as a separatate unitary member.
  • the collar may be formed by a plurality of parts, for example two "L" shaped parts which, when assembled onto the edges of the metal sieve element, will form a complete collar.
  • the attachment means might be provided on only two, opposed, sides of the sieve element, especially where the latter is self-supporting e.g. looped or welded wedge wire, perforated plate, or woven wire.
  • the attachment collar has a peripheral depending skirt 106, (net visible in Figure 2) the inner surface of which is undercut to form an inwardly directed lug 108, which engages beneath a corresponding lip 110 formed by an undercut sidewall of a groove 66 in the associated cross-member of the support frame 14.
  • each groove 66 is of generally "T"-shaped cross-section to secure together the edges of two adjacent modules.
  • the inner surface 68 of the skirt 60 beneath the lug 62 slopes outwardly to assist flexing of the skirt and/or groove wall during installation by applying downwards pressure to the module.
  • each attachment collar which, in use, will lie parallel to the material flow direction may have upstanding lips 70, having inner walls sloping upwardly and outwardly and vertical outer walls so that the lips 70 of adjacent modules abut to form a truncated triangular rib which serves to divert the material being screened away from the joint and towards the apertured portions of the sieve elements.
  • a depending skirt and grooved support frame is especially advantageous where the support frame is at least partially of synthetic plastics material.
  • alternative attachment means might be employed to secure the elements to the support frame.
  • discrete spigots or pegs might depend at intervals from the attachment collar to engage in corresponding holes in the support frame, perhaps with pairs of spigots of adjacent modules in the same hole.
  • the edges of the attachment collars might have several semi-cylindrical recesses, stepped so that when the edges of adjacent modules are juxtaposed, the recesses form counterbored holes through which headed spigots or studs are inserted to secure the modules to the support frame.
  • attachment means could also be adapted to secure the edges of the metal sieve elements to the synthetic plastics attachment strips.
  • the synthetic plastics attachment means might be adapted to secure the modules to each other as well as, or even instead of, to the underlying support structure.
  • the outer edges of the collars might be castellated and the modules secured together by a rod or other elongate member extending through the intercalated parts of adjacent modules.
  • the screen modules may cover more than one aperture of the lattice 14.
  • a screen module may be any desired multiple of lattice apertures e.g. 4 by 4, 4 by 1. If, as is envisaged, the screen module is attached only to the cross-members around its periphery, strip inserts may be installed in the grooves in intermediate cross-members, preferably conforming in cross-section to the groove, to prevent ingress and accumulation of the material passing through the superjacent sieve element.
  • the attachment means may itself be formed as a lattice or grid securing a plurality of the metal sieve elements together. Several such screen lattices might then be secured to a support frame as described hereinbefore.
  • the attachment means has a vertical slot 150 of a depth equal to that of the flange 115 of the sieve element so that the upper edge of the attachment means is level with the screen surface.
  • the inner wall 152 of the attachment means inclines downwardly and inwardly towards the middle of the sieve element, at an angle of about 45°, its uppermost edge 154 coinciding with the junction between the flange 115 and the transverse ribs 86. Consequently the apertured portion of the sieve element is not obstructed by the attachment means, permitting an open-area of as high as 92 per cent.
  • the attachment means may be attached resiliently to the flange or, and preferably, moulded directly onto the flange 115, which may be indented or apertured as at 156 for added security of attachment.
  • metal sieve elements having outwardly-directed flanges could be laid upon a support frame with their flanges supported by the cross-bars of the frame and clamped thereto by an attachment means in the form of a strip overlying adjacent flanges of each adjacent pair of elements and secured to the underlying cross-bar.
  • an attachment means in the form of a strip overlying adjacent flanges of each adjacent pair of elements and secured to the underlying cross-bar.
  • a synthetic plastics strip could be provided between the flanges and the support frame.
  • the overlying strip might have integral depending studs or ribs to project between the juxtaposed flanges and into a hole or slot in the cross-members.
  • such strip might have counterbored holes formed at intervals along its length and be secured by studs or spigots passing through these holes and registering holes in the support frame.
  • two parallel strips with stepped semi-cylindrical recesses might be combined to give the counterbored holes.
  • the synthetic plastics attachment means might be bonded to the periphery of the metal sieve element, for example to the flanges, where provided, perhaps even to a flat peripheral surface extending perpendicular to the plane of the element.
  • the metal sieve element might have a peripheral sidewall, extending generally perpendicular to the plane of the element, provided (for example by deformation) with a ridge to engage a recess in the synthetic plastics attachment means.
  • the recess may be preformed or may be formed by resilient deformation on insertion of the element.
  • the sieve element might be of any traditional construction, for example welded or looped wedge wire, perforated plate, woven wire, welded mesh.
  • Embodiments of the invention advantageously allow advantages of traditional screening media in particular applications to be realised in combination with those of synthetic plastics material such as lower noise level and modular construction with replaceable elements.
  • a wedge-wire type sieve element can be used yet individual screen modules, when worn, can be replaced quickly and easily and without special tools.
  • readily replaceable screen modules may be provided with woven wire or other high open area sieve elements such as are preferred for damp material having a high fines content.
  • Embodiments of the invention will generally be quieter in operation than conventional metal screens since the synthetic plastics attachment means may act as a shock absorber. It should be noted that the attachment means might be made from alternative material, for example rubber or other elastomeric material.
  • the smaller size of sieve element employed in modular construction will be less susceptible to resonance and reverberation, leading to reduced noise levels, particularly where the sieve element comprises perforated metal plate.
  • attachment means might be of wedge-shaped vertical cross-section so that the screening surface has a sawtooth sectional profile, the "steps" extending across the direction of flow of the material to be screened. This arrangement is particularly useful for screening slurries.
  • the invention also comprehends cylindrical or conical screens, for example centrifugal apparatus and trommel screens.
