Rock straining system

A straining system, comprising:

• an intake manifold having an intake plenum;
• a plurality of intake valves in fluidic communication with the intake plenum;
• each of the intake valves being respectively moveable between a first intake valve position that is open to admit flow through the intake valve into the intake plenum and a second intake valve position that is closed to prevent flow through the intake valve into the intake plenum;
• a plurality of strainer tubes;
• each of the strainer tubes having a rising section that contains a capped access port, an inlet, an outlet, and a flow pathway placing the inlet in fluidic communication with the outlet,
• the inlet being in fluidic communication with the intake plenum;
• the flow pathway extending in a downstream direction from the inlet towards the outlet and through at least the rising section, the flow pathway including a strainer hanger and a strainer basket located between the inlet and the outlet;
• and
• a discharge manifold having a discharge plenum;
• the outlet of each strainer tube being in fluidic communication with the discharge plenum for delivery of flow thereto;
• the discharge manifold having a plurality of discharge valves in fluidic communication with the discharge plenum;
• each of the discharge valves being respectively moveable between a first discharge valve position that is open to admit flow through the discharge valve from the discharge plenum and a second discharge valve position that is closed to prevent flow through the discharge valve from the discharge plenum;
• and
• wherein each strainer basket comprises a cone at a downstream end thereof, the cone tapering in an upstream direction from the downstream end;
• and
• wherein each strainer hanger of the plurality of strainer hangers includes at least one arcuate member with a radially outboard side welded to an interior diameter of the rising section, a radially inboard diameter of the arcuate member permitting passage therethrough of a corresponding one of the plurality of strainer baskets.
