Abstract

The present disclosure provides a fracturing fluid mixing equipment including a clear water supply system, at least two mixing systems, at least one powder tank, at least two powder conveying systems, a mixing tank, a feeding system and a power system. The clear water supply system has two parallel water supply paths which are connected to the mixing system and the mixing tank respectively. The powder conveying system is connected to the powder tank. There are same number of powder conveying systems and mixing systems which are connected in one-to-one correspondence. The mixing system is connected into the mixing tank. The feeding system adds powder by pneumatic conveying. The power system provides driving force by pure electric power and/or electro-hydraulic power. According to present disclosure, the power system can reduce fuel consumption and exhaust emissions. The feeding system can be compatible with various adding conditions of powders in different packaging, which can reduce the possibility of dust pollution, thereby reducing labor costs and occupational injuries and being more efficient and environmentally friendly.

First claim

What is claimed is:

1. A fracturing fluid mixing equipment, comprising:
(a) a clear water supply system comprising two parallel water supply paths;
(b) at least two mixing systems connected in parallel, each connected to one water supply path of the clear water supply system;
(c) at least one powder tank for storing powder;
(d) at least two powder conveying systems connected to the at least one powder tank, the number of the powder conveying systems being equal to that of the mixing systems, each of the powder conveying systems being correspondingly connected to one mixing system;
(e) a mixing tank connected with the other water supply path of the clear water supply system and an output end of the at least two mixing systems;
(f) a feeding system connected to the at least one powder tank, the feeding system being configured to convey powder from a supply source into the at least one powder tank by means of pneumatic conveying, wherein the feeding system includes an air compressor configured to convey the powder into the at least one powder tank by means of blowing under positive pressure, wherein the air compressor is configured to provide driving air source for a pneumatic component of the fracturing fluid mixing equipment, wherein the fracturing fluid mixing equipment further comprises a dust collecting system connected to the at least one powder tank, the air compressor being configured to provide a back-flushing air source past the at least one powder tank and to the dust collecting system positioned downstream from the at least one powder tank; and
(g) a power system configured to provide driving force by pure electric power and/or electro-hydraulic power.

2. The fracturing fluid mixing equipment according to claim 1 , the dust collecting system being downstream of the at least one powder tank in an air flow direction of a conveying airflow for further separating the powder before the conveying airflow is discharged.

3. The fracturing fluid mixing equipment according to claim 2 , wherein the dust collecting system and the at least one powder tank are in one to one correspondence, or one dust collecting system corresponds to two powder tanks of the at least one powder tank, or at least two dust collecting systems correspond to the at least one powder tank.

4. The fracturing fluid mixing equipment according to claim 1 , wherein a pressure sensor is provided in a conveying pipeline between the feeding system and the at least one powder tank.

5. The fracturing fluid mixing equipment according to claim 1 further comprising an electrical control system for controlling the operation of the fracturing fluid mixing equipment, the electrical control system having a remote control mode and/or a local control mode.

6. The fracturing fluid mixing equipment according to claim 5 , wherein the electrical control system is integrated with the power system.

7. The fracturing fluid mixing equipment according to claim 1 , wherein the at least two powder conveying systems are connected to one and same powder tank of the at least one powder tank, wherein the one powder tank of the at least one powder tank is divided into at least two separate storage spaces which are connected to the powder conveying systems in one-to-one correspondence, or there are at least two powder tanks of the at least one powder tank connected to the at least two powder conveying systems in one-to-one correspondence.

8. The fracturing fluid mixing equipment according to claim 1 , wherein a weighing device is provided below or on top of the at least one powder tank for weighing and displaying the weight of the powder in the at least one powder tank.

9. The fracturing fluid mixing equipment according to claim 1 , wherein the mixing tank is provided with a level meter for detecting liquid level in the mixing tank.

10. The fracturing fluid mixing equipment according to claim 1 further comprising an injection system, wherein an input end of the injection system is connected to one water supply path of the clear water supply system, and an output end of the injection system is respectively connected to an input end of each of the at least two mixing systems.

11. The fracturing fluid mixing equipment according to claim 1 further comprising a discharge system connected to an output end of the mixing tank.

12. The fracturing fluid mixing equipment according to claim 1 further comprising a carrier on which each system of the fracturing fluid mixing equipment is integrated.

13. The fracturing fluid mixing equipment according to claim 12 , wherein the carrier is a semi-trailer, a skid or a truck.

14. The fracturing fluid mixing equipment according to claim 12 , wherein the power system is arranged at one end of the carrier in a length direction of the carrier.

15. The fracturing fluid mixing equipment according to claim 12 , wherein the power system, the mixing tank, the at least two powder conveying systems, and the at least one powder tank are arranged in a length direction of the carrier successively.

16. The fracturing fluid mixing equipment according to claim 1 further comprising an electrical control system configured to selectively output a first solution from one of the at least two mixing systems and into the mixing tank while also inhibiting output of a second solution from another of the at least two mixing systems.
