Definitions
- the present invention relates to particle screening system industrial screens and more particularly to a screen module a plurality of which are retained by a supporting structure.
- apparatus comprising:
- a supporting structure adapted to support a plurality of said screen panel modules in side-by-side and/or end-to-end abutting relationship, the supporting structure comprising a plurality of supporting bars onto at least one of which is mounted a fall rail member, said screen panel module(s) comprising mating means adapted to engage with said rail member so as to secure said screen panel module(s) thereto.
- FIG. 1 is a schematic perspective view of a screen panel and support assembly therefor
- FIG. 2 is an exploded schematic sectional end view of a central support rail and an edge of a screen panel
- FIG. 3 is a schematic sectional end view of a support member supporting the rail of FIG. 2 and abutting edges of adjacent screen panels.
- the support assembly 2 includes a plurality of support bars 3 which are arranged to engage at least a portion of the periphery 4 of the panels 1 .
- the panels may be clamped into position with respect to bars 3 .
- the operation of the optional clamping arrangement 5 is described in the applicant's Australian Patent Application No. 27046/88.
- wedge means 11 drive member 10 downwardly onto support bars 3 to firmly secure screen module 1 in place.
- Rail member 6 is a central rail adapted to support in side-by-side abutting relationship adjacent screen panels 1 .
- Rail member 6 ′ is a side rail being essentially equivalent to one half of rail member 6 .
- Cut-outs 17 are provided in rail member and protuberances 20 in FIG. 2 cooperate with cut-outs 17 6 to provide means by which movement in directions B and C of panels 1 is prevented.
- Rail members 6 may be fastened to support bars 3 by means of bolt 7 as shown In FIG. 3 .
- Bolts 7 are located at various longitudinal locations along track 6 .
- rail members 6 (and 6 ′) are provided with protrusions 12 being designed to mate with recesses 14 in the edge 4 of the screen panel 1 . Additionally, protrusion 12 is provided with a lip 13 designed to engage with groove 15 in edge 4 of screen 1 thus providing means by which screen 1 is held firmly in place by track 6 .
- screen members 1 being formed of plastics material may be reinforced with reinforcing bars 16 extending longitudinally and/or transversely therein.
- screen members 1 are Individually individually snapped onto tracks 6 and 6 ′ by application of a force in the direction of arrow A. As a plurality of screen members replace much larger conventional unitary screen members this process is much easier and safer than otherwise possible. Once one screen member is in place, further screen members 1 are similarly snapped into tracks 6 and 6 ′ to abut with the screen member previously put in place and any adjacent screen members.
