摘要： A grit washer is disclosed having a bearing assembly which supports a conveyor and which is removably mounted to the exterior of the grit washer tank. With the bearing assembly being mounted to the exterior of the tank, the bearing assembly is easily accessible without the need to drain the tank or lift the screw conveyor out of the tank. The bearing assembly can therefore be easily inspected, repaired and/or replaced as necessary. The external placement of the bearing assembly also isolates the bearing assembly from the abrasive grit in the tank thereby minimizing the damage to the bearing assembly caused by the grit.

摘要： A filtering device suitable for filtering a flow of fluid in a channel includes a plurality of filter elements coupled to one another to define a filter loop. The filter loop is configured to position a filter element in the channel to filter a portion of the flow of fluid. The filtering device also includes a plurality of resilient seal members. Each seal member is coupled to one of the plurality of filter elements such that the seal member is at least partially compressed by an adjacent filter element. At least one seal member inhibits the flow of fluid between the filter element to which the seal member is attached and the adjacent filter element.

摘要： An assembly for removing grit from a fluid comprising a tank with a fluid inlet into the tank and a discharge from the tank. A flow directing assembly is positioned in the tank adjacent the fluid inlet and includes a substantially U-shaped surface opposite the fluid inlet such that fluid entering the tank through the inlet is caused to have a reversed flow in a direction more than 90 degrees from an inlet flow direction. At least one embodiment of the assembly further comprises a baffle positioned proximate the tank discharge to control flow adjacent the discharge. Yet a further embodiment of the assembly includes a screw conveyor positioned in a trough of the tank and a baffle is positioned proximate the trough to minimize fluid flow velocity adjacent to the screw conveyor.

摘要： A filter screen that is used in filtering water and that includes a frame and a grid assembly that is supported by the frame for movement. The grid assembly includes a continuous unbroken drive chain having a guide link, and a screen panel. The screen panel is coupled to the guide link for selective movement between an operating condition and a maintenance condition. When the screen panel is in the operating condition the screen panel is fixed relative to the guide link for movement with the guide link and for filtering water. In the maintenance condition, the screen panel is pivotable relative to the guide link to permit access to the interior of the filter screen for inspection of chain components.
