Abstract: A shock-absorbing suspension for a conveyor assembly includes brackets that attach to the parallel support beams of the conveyor. The brackets support corresponding saddles, that in turn, mount the conveyor assembly. In a preferred embodiment, the saddles are mounted above inverted U-shaped brackets that are attached to the top flange of the support beams. Dual coil springs are positioned vertically between the brackets and the saddles, with one spring on each side of the support beams. Within the springs are guide pins to restrict lateral movement, while adjustable fasteners preload the springs. In an alternate embodiment, the bracket/saddle combination is reoriented to provide increased overhead clearance. Each longitudinal end of the combination is covered by a skirt of flexible rubber to protect the interior from dust and debris.

Abstract: A sloped plate water clarifier is provided with multiple clarifying stages. Slurry enters a feeding and mixing passageway that contains chemical flocculant in the form of polymer gel logs. Agitating drums in the passageway provide controlled mixing of the slurry with the flocculant. At the end of the passageway the slurry flows over a static screen that separates the useable process product from solid refuse. The slurry passing through the screen flows into a settling tank containing sloped plates arranged in three ascending stages, with the plates in the uppermost stage being angularly adjustable. As the slurry rises inside the tank, the sloped plates allow the suspended solids in the slurry to settle and eventually accumulate on the tank bottom for periodic removal, including as an alternative by a venturi pump. The clarified water exits a spillway at the top of the tank.
