Abstract

A system for mixing fluids such as drilling fluids and which comprises an elongated container having a cylindrical shaped bottom. A suction conduit has an inlet in fluid communication with the interior of the container at about its central axis for withdrawing fluid from the container. An exterior conduit extends along the length of the container and has a plurality of spaced apart injection conduits extending into the container for injecting fluid therein in a direction to cause the fluid to swirl around the central axis of the container. A pump has its inlet coupled to the suction conduit and its outlet coupled to one end of the exterior conduit to cause the fluid in the container to spiral inward for flow through the suction conduit and to be pumped into the exterior conduit for injection through the injection conduits back into the container. An air bleed is provided for removing air from the interior of the container near its axis.
