Multi functional fracturing blender

A blending tub apparatus for use in well servicing operations, the blending tub apparatus comprising:

• a. a blending tub including a side wall and an enclosed lower surface;
• b. a particulate inlet positioned in the side wall of the blending tub which receives particulate matter for delivery into the blending tub;
• b. a fluid inlet positioned in the side wall of the of the blending tub which receives a first fluid for delivery into the blending tub;
• c. a slurry outlet positioned in the side wall of the blending tub below the fluid inlet which discharges the slurry composition for use in well servicing operations;
• and
• d. a mixing impeller suspended from above and within the blending tub, the mixing impeller comprising:
• i. a hollow central shaft extending along a longitudinal axis of the impeller having a longitudinal channel therethrough in the shape of a helical screw,
• ii. a plurality of blades that extend outward from a lower portion of the central shaft, wherein the blades are configured to generate an axial flow of the slurry composition in the blending tub,
• iii. two or more nozzles disposed longitudinally along the length of the central shaft, wherein slurry is lifted through the channel from a lower portion of the blending tub to a higher portion of the blending tub as the impeller is rotated during mixing of the slurry composition in the blending tub.

A blending tub system for use in well servicing operations comprising:

• a. a multi-sectional blending tub comprising:
• i. a side wall and an enclosed lower surface defining a blending cavity;
• ii. a removable divider insertable from the above and positioned within the blending cavity to separate the blending tub into a first section and a second section;
• iii. a first particulate inlet and a second particulate inlet positioned in the side wall of the blending tub, where the first particulate inlet receives particulate matter for delivery into the first section and the second particulate inlet receives particulate matter for delivery into the second section;
• iv. a first fluid inlet and a second fluid inlet positioned in the side wall of the of the blending tub and below the distribution chute, wherein the first fluid inlet receives a first fluid for delivery into the first section and the second fluid inlet receives a second fluid for delivery into the second section;
• v. a first mixing impeller suspended from above and within the first section and a second mixing impeller suspended from above and within the second section, wherein the first mixing impeller mixes the first particulate matter and the first fluid to produce a first slurry composition in the first section, wherein the second mixing impeller mixes the second particulate matter and the second fluid to produce a second slurry composition in the second section;
• vi. a first slurry outlet positioned in the side wall of the first section and below the first fluid inlet and a second slurry outlet positioned in the side wall of the second section and below the second fluid inlet, wherein the first slurry outlet discharges the first slurry composition and the second slurry outlet discharges the second slurry composition for use in well servicing operations.
• b. a particulate delivery system which delivers the particulate matter to the first and second particulate inlets of the blending tub;
• c. an intake manifold system including two or more intake pumps and two or more intake control valves for respectively controlling the intake of the first and second fluids to the first and second sections of the blending tub;
• d. a discharge manifold system including two or more discharge pumps and two or more discharge control valves for respectively controlling the discharge of the first and second slurry compositions from the first and second sections of the blending tub;
• e. a power generation system which powers and controls the particulate delivery system, the intake manifold system, and the discharge manifold system, and the first and second mixing impellers of the multi-sectional blending tub.
• f. a single transportable base on which the blending tub, the particulate matter delivery system, the intake manifold system, the discharge manifold system, and the power generation system are mounted.
