Abstract

A particle screening system is a modular industrial screen system having a number of screen panel modules supported side-by-side and/or end-to-end by a supporting structure assembly. The supporting structure assembly has a number of support bars arranged to support peripheral portions of each screen panel module by way of rail members. The rail members have protrusions which are designed to meet with recesses in the screen panel modules using a snap-engagement.

Description

This is a continuation of application Ser. No. 07/821,249 filed Jan. 10, 1992, now abandoned, which is a continuation of application Ser. No. 07/570,380 filed Aug. 21, 1990, now abandoned.
BACKGROUND OF THE INVENTION
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.
Currently available screen panels are generally large, heavy and cumbersome requiring considerable time and trouble to dismantle from a supporting structure.
SUMMARY OF THE INVENTION
It is the object of the present invention to provide an improved modular industrial screen system.
There is disclosed herein apparatus comprising:
at least one screen panel module,
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.
BRIEF DESCRIPTION OF THE DRAWINGS
A preferred form of the present invention will now be described by way of example with reference to the accompanying drawings, wherein:
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; and
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.
DETAILED DESCRIPTION
In the accompanying drawing, there is schematically depicted a plurality of screen panels 1 supported by support assembly 2. 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. Basically, wedge means 11 drive member 10 downwardly onto support bars 3 to firmly secure screen module 1 in place.
Onto support bars 3 are mounted rail members 6 and 6′. 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.
Referring to FIG. 2, 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.
Further, screen members 1 being formed of plastics material may be reinforced with reinforcing bars 16 extending longitudinally and/or transversely therein.
In use, 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.
It should be noted that minor changes are envisaged by the applicant. For example the specific shape of tracks 6 and the means by which the tracks 6 are anchored to support bars 3 may be altered without departing from the scope of the invention.
