Abstract:
1. A flow diverter assembly for enhancing the operational effectiveness of a screen separator for separating solids from liquids in a supply of material from a flow line, comprising: a conduit coupled to the flow line for receiving material from the flow line, wherein the conduit further comprises a ramp for a first deceleration of the flow of the material and a first directional change of flow of the material; an end wall coupled to the conduit, wherein the end wall causes a second deceleration of the flow of material and a second directional change of flow of the material; a half pipe assembly proximate to and spaced apart from the end wall, wherein the half pipe assembly comprises an inner curved surface for a third deceleration of the flow of material and a third directional change of the flow of the material; and a material discharge area between the end wall and the half pipe assembly, wherein the flow of the material passes through the material discharge area and is discharged to the screen for separating solids from liquids, wherein the conduit defines a sidewall such that the ramp extends upwardly from the sidewall of the conduit at an angle of about 35° to 55° relative to the sidewall of the conduit, and wherein the material flows through the half pipe assembly in a circular vortex path along the inner curved surface of the half pipe assembly, thereby substantially reversing the flow of the material relative to the flow of the material entering the half pine assembly prior to discharging the material to the screen through the material discharge area.
