    摘要： Solids mixing well structure and methods are disclosed for mixing a solid having a first specific gravity with a fluid having a second specific gravity to produce a slurry having an intermediate specific gravity and a resultant pressure greater than atmospheric pressure. The solids can then be transported in the form of a slurry using the resultant pressure. At no time do the solids come in contact with a pump member. The apparatus and methods are particularly suited for transporting coal and solid waste material. No moving parts are required other than a pump to supply fluid pressure. A first cylindrical member receives at its inlet fluid at a pressure greater than atmospheric pressure and delivers the fluid at a first pre-determined pressure to a mixing region. A second structure receives at its inlet solids at atmospheric pressure and delivers the solids at the first pre-determined pressure to the mixing region down stream of the fluid. The fluid and solids, having substantially the same pressure in the mixing region, readily mix. The resulting slurry exits the mixing region and flows through a third structure to a discharge port. The slurry exits the discharge port at a second pre-determined pressure greater than atmospheric pressure, and equal to the pressure the slurry would have had if directly pumped at the horsepower of the pump supplying fluid pressure.

    摘要： An apparatus and method for mixing liquid or a drilling mud with solids and a second liquid is disclosed. The apparatus provides an annular housing having a plurality of mixing chambers. An inlet passageway is tangentially connected to the innermost mixing chamber for feeding slurry material to be mixed with solids axially fed into the same mixing chamber. A discharge port is further provided and connected to the outermost mixing chamber for tangentially discharging the homogeneous mixture of slurry and solid materials from the outer mixing chamber at high velocities to an elevation above the inlet. The mixing operation is enhanced by the liquid/solid mixture spilling over a first partition wall and retaining its rotational velocity and direction of rotation while passing under a second partition wall and finally out the discharge port.
