Abstract
A system for electric-motor driven transportation mechanism for fracturing operations is disclosed. The system includes at least one transportation mechanism to transport blender components for a blender fluid from a first tub that may be a proppant hopper to a second tub that may be a blender tub and that may be associated with a fracturing blender; an electric motor and a control unit associated with the at least one transportation mechanism; and at least one variable frequency drive (VFD) associated with the electric motors for real time control of a speed associated with the at least one transportation mechanism.
Claims (44)
1. A fracturing system comprising at least one transportation mechanism to transport blending components from a first tub to a second tub through chutes that are provided in side areas between the first tub and the second tub and that comprises the at least one transportation mechanism, wherein the at least one transportation mechanism is subject to real-time control of a frequency or speed based in part on input from at least one variable frequency drive (VFD) to an electric motor and a control unit that is associated with the at least one transportation mechanism.
2. The fracturing system of claim 1 , wherein the at least one transportation mechanism is associated with or comprises a direct drive coupling, a belt driven coupling with augers, or a gear driven coupling.
3. The system of claim 1 , further comprising:
a mobile unit comprising the at least one VFD and the electric motor, wherein the at least one VFD is also adapted to be controlled by the control unit.
4. The fracturing system of claim 1 , further comprising:
two transportation mechanisms, a first one of the two transportation mechanisms aligned in a first angle with respect to a bottom of the first tub and a second one of the two transportation mechanisms in a second angle with respect to the first angle of the first one of the two transportation mechanisms.
5. The fracturing system of claim 1 , further comprising:
a conveyer belt system or an auger system to function as part of the at least one transportation mechanism, the conveyer belt system or the auger system comprising buckets, paddles, or scoops to transport the blending components.
6. The fracturing system of claim 1 , further comprising:
at least one vehicle or trailer of a fracturing fleet comprising thereon one or more of the first tub or the second tub, and comprising thereon the electric motor, the control unit, and the at least one VFD to support blending operations performed on the at least one vehicle or trailer.
7. The fracturing system of claim 1 , wherein the at least one transportation mechanism is movable into the first tub to access the blending components.
8. The fracturing system of claim 1 , wherein the at least one transportation mechanism comprises at least one base transportation mechanism to displace the blending components towards at least one side transportation mechanism of the at least one transportation mechanism, the at least one side transportation mechanism to move the blending components from the first tub to the second tub using the chutes.
9. The fracturing system of claim 1 , further comprising:
one or more second electric motors, the one or more second electric motors and the electric motor to function in a synchronous operation, wherein the one or more second electric motors is associated with multiple transportation mechanisms, and wherein the blending components are continuously moving and are devoid of accumulation in any areas within at least the first tub.
10. The fracturing system of claim 1 , further comprising:
a mobile unit to comprise the control unit as remotely located thereon, relative to the electric motor, to control the at least one VFD for the electric motor.
11. A method comprising:
providing a fracturing system which comprises at least one transportation mechanism to transport blending components from a first tub to a second tub through chutes that are provided in side areas between the first tub and the second tub and that comprises the at least one transportation mechanism; and
providing real-time control of a frequency or speed for the at least one transportation mechanism based in part on input from at least one variable frequency drive (VFD) to an electric motor and a control unit that is associated with the at least one transportation mechanism.
12. The method of claim 11 , further comprising:
associating the at least one transportation mechanism within the chutes; locating the second tub within the first tub;
enabling at least part of the at least one transportation mechanism to move the blending components to the side areas; and
associating the at least one variable frequency drive (VFD) with the electric motor, the control unit, and at least one transportation mechanism.
13. The method of claim 11 , wherein the at least one transportation mechanism is associated with or comprises a direct drive coupling, a belt driven coupling with augers, or a gear driven coupling.
14. The method of claim 11 , further comprising:
locating the at least one VFD and the electric motor on a mobile unit; and
adapting the at least one VFD to be controlled by the control unit.
15. The method of claim 11 , further comprising:
providing a first transportation mechanism of the at least one transportation mechanism to be aligned in a first angle with respect to a bottom of the first tub; and
providing a second transportation mechanism of the at least one transportation mechanism to be aligned in a second angle with respect to the first angle of the first transportation mechanism.
16. The method of claim 11 , further comprising:
enabling a conveyer belt system or an auger system to function as part of the at least one transportation mechanism; and
enabling buckets, paddles, or scoops on the conveyer belt system or the auger system to transport the blending components.
17. The method of claim 11 , further comprising:
providing the electric motor, the control unit, the at least one VFD and one or more of the first tub or the second tub on at least one vehicle or trailer of a fracturing fleet; and
performing blending operations for the blending components on the at least one vehicle or trailer.
18. The method of claim 11 , further comprising:
enabling movement of the at least one transportation mechanism into the first tub to access the blending components.
19. The method of claim 11 , further comprising:
displacing, using at least one base transportation mechanism of the at least one transportation mechanism, the blending components towards side transportation mechanisms of the at least one transportation mechanism comprising; and
moving, using the side transportation mechanisms, the blending components from the first tub to the second tub using the chutes.
20. The method of claim 11 , further comprising:
associating the electric motor and one or more second electric motors with multiple transportation mechanisms of the at least one transportation mechanism; and
synchronously operating the electric motor and the one or more second electric motors to cause the blending components to be continuously moving and to be devoid of accumulation in any areas within at least the first tub.
