Modular screen belt

Abstract

A modular belt constructed of belt modules having a large open area, making the belt suitable for use as a traveling water screen. The modules include an intermediate portion composed of intersecting sets of link elements and transverse elements that form a gridlike pattern. Openings bounded by the walls of consecutive link elements and transverse elements form channels through the belt for the flow of water. The modules are connected together by hinge rods to form a belt that can be used as a water screen. Detachable flights or scoops for lifting debris or fish out of a stream are attachableto base modules.

Description

Background technique The present invention generally relates to a mobile water filter screen for filtering debris and fish from water streams, and more specifically, to a modular mesh belt suitable for openings that work as a mobile water filter screen. Many industrial processes use water from rivers, lakes and oceans. The water put into production equipment must be filtered to prevent debris from clogging the equipment and causing damage. The water filter screen can filter and remove debris from the incoming water flow before the debris enters the equipment. Modular plastic conveyor belts, originally designed to convey items, have begun to be used as mobile water filters. The INTRALOX1800 series MeshTop mesh belt, manufactured and sold by Intralox, L.L.C of Harahan, Louisiana, USA, is designed as a mobile water filter. This water filter is a heavy-duty filter with many narrow slits through which water can flow but not debris. These narrow slots can make the mesh belt partic...

Problems solved by technology

However, in rapidly flowing water streams, for example upstream of a suction-operated cooling water inlet, the mesh belt can significantly impede the water flow
