Abstract
A self-leveling mixing apparatus includes a transportable skid frame. A mixing tub is supported from the frame in a manner such that the tube is movable between first and second positions relative to the frame. The tube has a tub fluid outlet defined in a lower portion thereof. A suction conduit is supported from the skid frame for transport therewith and includes a manifold inlet, a manifold outlet, and a tub outlet conduit portion located upstream of the manifold outlet and connected to the tub fluid outlet. A leveling valve is also included and is disposed in the suction conduit upstream of the manifold outlet for controlling a level of fluid in the tub. A connector linkage operably connects the tube and the leveling valve for adjusting the leveling valve in response to movement of the tub relative to the skid frame.
