Definitions
- This invention relates to screening apparatus.
- the invention relates to vibratory screening apparatus including a polymeric screening panel, screening modules for use in such screening apparatus, and methods for their connection, and for illustrative purposes reference will be made to this application.
- this invention or elements of it may find application in other screening applications such as fixing rigid screen panels to a support frame of such an apparatus, and in stretched screen apparatus.
- Plastic screens by their very nature are flexible and unless adequately supported and mounted in the apparatus are able to flex. When the screens are allowed to flex excessively the openings through the screen become distorted and the screen allows larger particles than intended to pass through the screen, or fails to grade to a sharp cut-off on particle size.
- FIG. 7 discloses a variety of screen member constructions comprising screen member modules, most having steel reinforced edge portions.
- the modules are adapted to be assembled in multiples to a support structure, adjacent modules abutting with complementary halves of a bead arrangement adapted to engage a profiled support bar which retains the modules in relative location.
- FIG. 7 there is provided an unreinforced screen panel adapted to snap into a stiffening grid of support bars assembled longitudinally and transversely to a conventional screen deck.
- the upper edges of the longitudinal and transverse members have reentrant- section grooves into which corresponding beads of adjacent unreinforced screen panels are inserted and retained thereby.
- This construction has the advantage that the screen panels are readily replaceable, the worn panels are recyclable, and the screen assembly in use presents an uninterrupted, flat screen surface.
- the disadvantages are that the screen panels are necessarily small since the span of the flexible polyurethane material comprising the screen panel must be controlled to prevent undue distortion by flexing in use, at reasonable web thicknesses.
- the smallness of the panels with their peripheral mounting portions reduces the effective screen area.
- the supporting grid of longitudinal and transverse members is a complicated arrangement of interlocking steel cored polyurethane pieces. The arrangement is accordingly difficult to mount and dismount.
- the end portions of the panels and frames overlying the standard-pitch (24" or approximately) screen deck support bars are adapted to be engaged by and secured to the deck support bars by a lower, bolted- down portion adapted to receive the frame and panel ends, and a locking piece overlaying the panel end edges and engaging the bolted down portion.
- the screening panel is only retained against downward flexing on the intermediate support bar.
- the screening panels that allow the screening web to impact on the intermediate support tend to suffer from impact tearing of the screening panels that gives the appearance of a cut failure.
- Polyurethanes are resistant to abrasion wear but are susceptible to cut damage.
- the screening panels reach sufficient amplitude in upward vibration to cause some loss of grade control in screening.
- the securing means intrudes onto the plane of the screening surface thus tending to interrupt free flow of particles across the screening surface.
- screening module for a vibratory screen deck including a screen support member releasably securable to said screen deck and having a peripheral frame and an intermediate strut therewithin, and a polymeric screen member releasably engaged by snap-in connection with each of said peripheral frame portion and said intermediate strut, said intermediate strut being located whereby flex of said polymeric screen member is controlled.
- the screen support member may be of any suitably rigid construction material.
- the screen support member may be formed of metal or rigid plastic.
- the screen support member may include an integral or assembled construction of supporting frame and intermediate strut.
- the screen support member may for example include an integral supporting frame to which is assembled the intermediate strut.
- the strut may be selectably located within the frame.
- the screen support member may include an integral rigid metal frame and intermediate strut.
- the screen support member is of moulded polyurethane or other plastics construction and including an integral stiffening frame and intermediate strut core of rigid construction.
- the screen support member may be configured whereby the length thereof is selected to span adjacent rails of a conventional screening deck.
- the screen support members may be adapted to span 3 or more support rails, or may be adapted to interconnect in spanning a pair of support rails.
- the screen support member may be of width selected to span the length of the screen deck support rails.
- the screen support frame may be secured to the screen deck by any suitable means.
- the screen support frame may be provided with engagement means adapted to engage complementary engagement means provided on the screen deck support rails.
- the engagement means may take the form of a bolt or stud on either of the screen support frame or the supporting rail and adapted to pass into a hole for securing with a nut, or a captive nut as the case may be, on the other.
- the screen support frame be secured to the support framed by means selected to provide both intimate attachment of the screen support frame to the supporting rails as well as interconnection between adjacent modules on the screen deck.
- the ends of the screen support frames may for example be provided with end portions specifically configured to accept fastenings that interconnect adjacent screen support frames as well as securing the adjacent screen support frames together, as described hereinafter with reference to modular screens generally.
- the assembled screening modules may be secured to the screen deck, it is preferred that the securing means be selected whereby the securing means does not extend above the surface of the screening panels, whereby an uninterrupted screening surface may be maintained. It is also preferred that the securing means be installed before the screening panels are installed on the screen support members whereby the screen panels may overlie the securing means.
- the intermediate strut may take the form of one or more strut portions extending from the periphery of the screen support member, whereby the maximum unsupported span of the screen panel is reduced to control screening grade.
- the intermediate strut may take the form of an orthogonal array of strut portions disposed between the opposed sides and opposed ends of the screen support member to reduce the open area of the support member to panes.
- the intermediate strut may form other arrays such as an X-shaped array arising from the corners of the peripheral frame, or an annulus supported within the peripheral frame by radial strut portions.
- the intermediate strut may be of lesser plan cross-section than the necessary cross-section of the peripheral frame or other frame element necessary to support the periphery of the screen panel.
- the plan cross section of the intermediate strut may be of the minimum dimension required to accommodate the snap-in connection.
- the intermediate strut may also be interrupted to minimize the presented area.
- the screen support may be relatively longer than it is wide.
- the screen support frame may be configured to accept two or more screen panels.
- the screen panels may be selected to have square symmetry whereby the panel may be inserted in selected orientations.
- the screen support member may be provided with a transverse screen panel mounting portion effectively dividing the screen support frame into the necessary peripheral support configuration for use with multiple screen panels.
- the screen support frame is configured to accept two square screen panels.
- the screen panels may be of any suitable resilient material selected to exhibit the resistance to abrasive wear characteristic of polyurethane screening panels.
- the screen panels may be moulded from polyurethane. Since it is an advantage to be able to recycle the worn screen panels, it may be preferable to mould the screen panels from polyurethane alone, however, recyclability being a relative term, it may be possible or appropriate to provide the polyurethane screen with some form of reinforcing such as cord reinforcing or other material that may be co-processed with the polyurethane or steel wire reinforcing from which the bulk of the screen panel material may be readily stripped.
- the screen panels are preferably sized to be flush-edged with the screen support member in use whereby the assembled screen modules formed therewith may in assembly on a screen deck present a continuous screening surface.
- the snap-in connection may take any suitable form at least in part dictated by the nature of the selected screen support member and screen panel.
- the snap-in connection may comprise complementary snap-in components formed integrally with or assembled to the respective screen support member portions and the screen panels.
- the snap-in components are integrally formed on their respective components.
- the snap-in component may be inherent in the sections used in fabricating the member.
- the snap-in component may be moulded into the polyurethane.
- this be integrally moulded in the formation of the screen panel.
- the snap-in connection is also preferably selected whereby the snap-in connection is universal for connecting the screen panel to the screen support member. By this means it is not material whether a particular peripheral edge of the screen panel adjoins a peripheral edge of the screen support member or any intermediate support between screen panels.
- the snap-in component on the screen support member may for example include an upstanding ridge extending about the periphery of a screen panel mounting portion of the screen support member the ridge having on its outward facing surface a peripheral groove.
- the corresponding snap-in component of the screen panel may for example comprise a reentrant channel having a ridge adapted to engage the groove on the screen support member when the channel is deformed thereover.
- the shape and dimensions of the respective ridges and channel are preferably selected such that any intermediate support portion of the screen support may accommodate the snap-in components of adjacent screening panels whereby the panels are retained in close mutual abutment.
- the peripheral snap-in components of one or more of the screening panel or screen support member may be continuous or may be interrupted.
- peripheral security of the snap-in connection may be enhanced by provision of a double-engaging snap-in connection.
- the peripheral groove of the upstanding ridge may be supplemented by an undercut on the inner periphery of the upstanding ridge, whereby the reentrant channel may engage both the undercut and the peripheral groove.
- the snap-in connection between the intermediate strut and the screen panel may take any suitable form. Since the role of the snap-in connection to the intermediate strut is one of preventing flex of the web of the screening panel rather than providing the peripheral support required by the panel as a whole, the snap-in connection may be by its nature similar to or different from the peripheral snap-in connection. Where the intermediate strut comprises an array extending across the span of the screen support member it may be desirable to interrupt the snap-in component of either the panel or the strut.
- the snap-in component associated with the screen panel is preferably selected whereby the screening are occluded thereby does not substantially extend beyond the area occluded by the plan section of the intermediate strut itself.
- this invention resides in a method of mounting screening modules to a support rail of a screen deck including the steps of:- providing the screening module with an end portion adapted to overlie a support rail of a screening deck and having a recess formed therein defining a shoulder, said shoulder having a locating groove; abutting said module recess-to-recess with an adjacent module on said support rail; inserting into said recess a collet adapted to coact with said locating groove and the corresponding locating groove of the adjacent screening module to locate said screening modules in abutment; and fastening said modules with fastening means adapted to cooperate with said collet to secure said modules to the support rail.
- this invention resides in a screening module including:- an end portion adapted to overlie a support rail of a screening deck; a recess formed in said end portion and defining a shoulder; a locating groove formed on said shoulder; a collet adapted to coact with said locating groove and the corresponding locating groove of an adjacent screening module to locate said screening modules in abutment; and fastening means adapted to cooperate with said collet to secure said modules to the support rail.
- the end portion may be adapted to overlie the support rail by any suitable means which will be at least in part dictated by the nature of the support rails.
- the support rails comprise a flat mating surface which is stiffened by virtue of being formed from one flat of metal angle stock. Accordingly, the end portion is preferably formed having a flat lower mating surface. Since the support rails have a width that occludes a portion of the screening area, it is preferred that the end portions do not excessively further occlude the available screening area.
- the end portions may be formed of or incorporate a metal angle section whereas the remainder of the frame or core may be fiat bar. The use of angle in the end portions tends to stiffen the structure at its ends where vibrating loads are applied by the screen deck.
- the recess may be formed by any suitable means dictated by the nature of the end portion.
- the recess may be wholly formed in the polyurethane or the core may be modified in its fabrication to accommodate the recess formed in the polyurethane.
- the recess may be of any shape consistent with producing the aforesaid shoulder.
- the recess is of sufficient depth to accommodate the fastening means whereby in use the fastening is wholly located beneath the screen surface.
- the locating groove is preferably in the form of a chordal or arcuate groove in the shoulder, the line or apex respectively of which is disposed to the side of the fastening away from the abutment with the adjacent panel.
- the recess be substantially semicircular in plan and that the locating groove comprise an arcuate groove substantially coaxial with the recess.
- the locating groove may be of any suitable section consistent with engagement by a collet to locate the screen module in abutment with an adjacent screen module.
- the groove may be of rectilinear section, part-round section or the like.
- the groove is of a section whereby mutual engagement of the collet with the grooves of the adjacent modules serves to urge the modules into abutment and alignment.
- the preferred arcuate groove may be provided with at least one ramped face against which the collet may act to provide alignment and abutment of the modules.
- this invention resides in screening apparatus including a screen deck and a plurality of abutting screening modules in removable attachment therewith to form a substantially contiguous screening surface, each said screening module including a screen support member having a peripheral frame and an intermediate strut therewithin, and a polymeric screen member releasably engaged by snap-in connection with each of said peripheral frame portion and said intermediate strut, said intermediate strut being located whereby flex of said polymeric screen member is controlled, said removable attachment including an end portion of said screen support member adapted to overlie a support rail of said screening deck, a recess formed in said end portion and defining a shoulder, a locating groove formed on said shoulder, a collet adapted to coact with said locating groove and the corresponding locating groove of an adjacent screening module to locate said screening modules in abutment, and fastening means adapted to cooperate with said collet to secure said modules to the support rail.
