Abstract

Mounting system for mounting a screen panel in a continuous belt screen assembly. The mounting system includes a first and second set of links, the second set of links being configured to be interposed between, and aligned with, the first set of links. Each respective link defines a respective recessed portion. The continuous belt screen assembly has a pair of spaced, opposed endless belts and a plurality of screen panels arranged between the belts. The sets of links are mountable in spaced, parallel relationship between the belts. The second recessed portions face in a direction opposite to that of the first recessed portions, in use, so that the recessed portions define a channel in which the screen panel is receivable.

Abstract

A locking assembly is provided for a cover. The cover is a substantially rigid cover configured to close off an opening to a void, said void bounded by a side wall. The cover defines a top side and an opposed underside. The locking assembly includes a mounting arrangement mountable to the underside. A link is pivotally connected to the mounting arrangement. The link defines a first end and a second, free end. A locking member is carried by the second, free end of the link. The locking member frictionally engages the side wall of the void in a locking position, in use. An actuating member connects to the link and is accessible via the top side. The actuating member displaces the link relative to the mounting arrangement to cause the locking member to frictionally disengage from the side wall of the void to a disengaged position.

Abstract

A screen (10) includes a support structure (14). A plurality of elongate screening elements (18, 20) is arranged in spaced relationship transversely on the support structure to define elongate screening apertures (22) between adjacent screening elements (18, 20). Each screening element (18, 20) has a screening head (31, 34) defining a screening surface (24, 26), the screening surfaces (24, 26) all being at the same height relative to the support structure (14). Adjacent screening elements (18, 20) are of different widths relative to each other with a transverse dimension of the aperture (22) being less than a width dimension of the wider screening element 18. The screening head (31) of the wider screening element (18) is shaped to maintain a substantially constant screening aperture (22) between the screening elements (18, 20) during a predetermined amount of wear of the wider screening element (18).

Abstract

A continuous belt screen assembly and system used for filtering fluid for various municipal and industrial purposes. The assembly includes a pair of spaced, endless belts, lifters, and screen panels. Each lifter is operably mounted to the pair of belts for lifting of solid waste out of the fluid in the channel. Each of the screen panels can be interposed between lifters and secured in place by opposing slots defined by the lifters. The endless belts can include toothed drive links, with the ends of the teeth extending with the ends of the drive links to define an involute profile. The lifters can include a sleeve portion for receiving a pivot shaft and a paddle portion extending from the sleeve portion, terminating at a free end that can be contoured to have teeth. The lifters can be a flexible material configured to deflect.
