초록 ▼

A blender apparatus is disclosed which is useful for mixing dry particles with a liquid. In a specific application, dry cement is mixed with water to obtain a cement slurry for cementing oil and gas well casings. The cement particles and water are directed into a disperser unit, in which the water contacts the cement particles at an acute angle. The resulting slurry is passed into a volute casing positioned in a tank. As the slurry swirls within the volute, it develops a vortex action, which continuously circulates the mixture in the tank. The slurry is pumped from the tank and split into two streams. Part of the slurry stream flows directly to a pumper unit, for injection into the well. The remainder of the stream is pumped through a restricting nozzle and back through the volute, to provide a continuous recycle which enhances blending of the dry material with the liquid.

An apparatus for mixing dry particles with a liquid which comprises, in combination; a hopper for storing a charge of dry particles, which hopper includes a discharge outlet; a first conduit section which communicates with the discharge outlet; a disperser means, the disperser being defined by a main chamber, the chamber including a first vertical nozzle and a first compartment positioned below the first nozzle, the nozzle communicating with the first conduit section and with the first compartment, the chamber further including a second compartment which surrounds the first compartment and which communicates with the first compartment, a source of liquid connected to the second compartment, air inlet ports in said chamber, the chamber further including a vane member which is positioned adjacent to the second compartment and which includes an outer surface in communication with the first compartment, the vane member being spaced from the first nozzle with the space defining an air intake passage which commmunicates with the air inlet ports in the chamber; the dry particles in the hopper being passed into the first compartment through the first nozzle, liquid received in the second compartment being passed into the first compartment to thereby mix with the particles and produce a slurry mixture; a tank container which includes a vent opening therein; a volute casing which is positioned in the tank container; a second conduit section which connects the first compartment of the disperser with the volute casing; the slurry mixture being delivered into the volute casing through the second conduit section, and circulated within the volute casing and within the tank container; a third conduit section which connects the tank container with a fourth conduit section; a pump means which is installed in the third conduit section; the fourth conduit section being connected into the second conduit section and into a use point; a second nozzle which is positioned within the fourth conduit section; wherein a portion of the slurry mixture is continuously circulated from the tank container through the pump means and second nozzle, and a portion of the slurry mixture is continuously delivered to the use point.
