Abstract
An oilfield material reservoir comprises a body and a base connected to and positioned beneath the body. The body has an upper end, a lower end, a sidewall having a first side and a second side extending between the upper end and the lower end forming a recess, and a partition positioned within the recess adjacent to the lower end and extending between the first and second sides of the sidewall. The base has a discharge opening formed within the lower side, and a plurality of augers extending between the first and second ends. The plurality of augers have opposing-hand flights configured to drive an oilfield material toward the discharge opening of the base.
Claims21
An oilfield material reservoir, comprising:
- a body with an upper end, a lower end, a sidewall having a first side and a second side opposite the first side and extending between the upper end and the lower end forming a recess, and a partition positioned within the recess adjacent to the lower end and extending between the first and second sides of the sidewall;
- and
- a base positioned adjacent to and beneath the body, the base having an upper side, a lower side opposite the upper side, a first end, a second end opposite the first end, a discharge opening formed within the lower side, and a plurality of augers,
- wherein each of the augers have a central shaft extending across the body from the first side to the second side of the body, the augers having opposing-hand flights on opposite ends of the central shaft, the flights of the augers configured to drive an oilfield material from the first and second sides of the body toward the discharge opening of the base.
An oilfield material reservoir, comprising:
- a body with an upper end, a lower end, a sidewall having a first side and a second side opposite the first side and extending between the upper end and the lower end forming a recess, and a partition positioned within the recess adjacent to the lower end and extending between the first and second sides of the sidewall;
- a base positioned beneath the body, the base having a lower end at least partially surrounding a discharge opening, and a plurality of augers, the wherein each of the plurality of augers have a central shaft extending across the body from the first side to the second side of the body, the augers having opposing-hand flights on opposite ends of the central shaft, the flights of the augers configured to drive oilfield material from the first and second sides of the body toward the discharge opening of the base;
- and
- one or more motive elements configured to cause one or more of the central shafts of the plurality of augers to rotate thereby driving the oilfield material toward the discharge opening of the base.
A method, comprising:
- introducing an oilfield material into an oilfield material reservoir having a body and a base positioned beneath the body, the body having an upper end, a lower end, a sidewall having a first side and a second side and extending between the upper end and the lower end forming a recess, and a partition positioned within the recess adjacent to the lower end and extending between the first and second sides of the sidewall, the base having a discharge opening formed within a lower side, the body having a plurality of augers disposed therein, each of the augers having a central shaft extending across the body from the first side to the second side of the body, the augers having opposing-hand flights on opposite ends of the central shaft, the flights of the augers configured to drive an oilfield material from the first and second sides of the body toward the discharge opening of the base;
- and
- rotating the central shafts of the augers while introducing the oilfield material and directing the oilfield material toward the discharge opening of the base via the flights of the plurality of augers.
