Description

Technical Field

[0001] This utility model relates to the field of fracturing fluids, and more specifically, to a recycling and filtration device for the reuse of water-based fracturing fluids. Background Technology

[0002] Fracturing fluid recovery and filtration is a crucial step in oil and gas field development, especially after hydraulic fracturing operations. Fracturing fluid is a liquid produced during hydraulic fracturing to improve oil and gas flowability and production. If fracturing flowback fluid (i.e., the fracturing fluid returned after use) is discharged or reinjected into the formation without effective treatment, it can cause serious environmental pollution and damage. With increasing environmental awareness and stricter environmental regulations, the harmless treatment of fracturing flowback fluid has become increasingly important.

[0003] Currently, it is inconvenient to clean the equipment after filtering the fracturing flowback fluid. Therefore, we have made an improvement and proposed a recycling and filtration device for water-based fracturing fluid reuse. Utility Model Content

[0004] To address the problems mentioned in the background section, this utility model provides the following technical solution:

[0005] A water-based fracturing fluid recycling and filtration device includes a base, on which a bracket is fixedly mounted. A lower guide rail and an upper guide rail are welded to the bracket. A lower drive mechanism is mounted on the lower guide rail, and a mounting frame is slidably connected to it. A lower funnel is integrally formed at the bottom of the mounting frame. An upper drive mechanism is mounted on the upper guide rail, and an upper funnel is slidably connected to it. A rectangular frame is disposed within the upper funnel, and a rectangular filter screen is integrally formed within the rectangular frame. A rod is fixedly mounted on the rectangular frame. A socket is fixedly mounted on the outer wall of the upper funnel, and a slot is provided on the socket to match the rod. A sedimentation tank is disposed on the base, and a drain outlet is provided on the left side wall of the sedimentation tank. A circular filter screen is disposed within the drain outlet, and a drain valve is connected to the drain outlet.

[0006] As a preferred technical solution of this utility model, a downward sliding bar is fixedly installed at the bottom of the mounting frame.

[0007] As a preferred technical solution of this utility model, the lower drive mechanism includes a lower motor fixedly installed on the side wall of the lower guide rail, a lower threaded rod fixedly installed at the output end of the lower motor, the lower threaded rod being threadedly connected to the lower slide bar, and the lower threaded rod being rotatably connected to the lower guide rail.

[0008] As a preferred technical solution of this utility model, an upper sliding bar is fixedly installed at the bottom of the upper funnel.

[0009] As a preferred technical solution of this utility model, the upper drive mechanism includes an upper motor fixedly installed on the side wall of the upper guide rail, an upper threaded rod fixedly installed at the output end of the upper motor, the upper threaded rod being threadedly connected to the upper slide bar, and the upper threaded rod being rotatably connected to the upper guide rail.

[0010] As a preferred technical solution of this utility model, a switch group is provided on both the lower guide rail and the upper guide rail.

[0011] As a preferred technical solution of this utility model, the top of the rectangular frame is welded with a lifting lug.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In the solution of this utility model:

[0014] 1. After the fracturing fluid is added through the upper funnel, it first passes through a rectangular filter screen, then through the lower funnel, and finally flows into the sedimentation tank for sedimentation. When it is discharged after sedimentation, it can still be filtered. This allows for direct sedimentation after filtration, which is not only convenient to use, but also achieves a dual impurity separation function, resulting in better impurity separation effect.

[0015] 2. The upper motor's output drives the upper threaded rod to rotate, which in turn moves the upper slide bar, which in turn moves the upper funnel so that it is no longer above the lower funnel, allowing for cleaning of the lower funnel. When cleaning the rectangular filter screen, use external tools with lifting lugs to remove the screen for easier cleaning. When cleaning the sedimentation tank, start the lower motor. The lower motor's output drives the lower threaded rod to rotate, which in turn moves the lower slide bar, which in turn moves the mounting frame, which in turn moves the lower funnel so that it is no longer above the sedimentation tank, facilitating cleaning of both the sedimentation tank and the filter screen.

A rod 8 is fixedly installed on a rectangular frame 21, which drives the rod 8. A socket 9 is fixedly installed on the outer wall of the upper funnel 7, and a slot 10 is provided on the socket 9. The slot 10 matches the rod 8. A sedimentation tank 11 is provided on the base 1, which settles impurities in the liquid. A drain port is provided on the left side wall of the sedimentation tank 11, and a circular filter screen 19 is provided in the drain port for further filtration. A drain valve 12 is connected to the drain port. After the liquid settles, the drain valve 12 is opened for safe and reasonable discharge.

The lower threaded rod 15 is threadedly connected to the lower slide bar 13. The rotation of the lower threaded rod 15 drives the lower slide bar 13 to move. The lower threaded rod 15 is rotatably connected to the lower guide rail 3.

[0034] An upper slide bar 16 is fixedly installed at the bottom of the upper funnel 7, and the upper slide bar 16 drives the upper funnel 7 to move.

[0035] The upper drive mechanism includes an upper motor 17 fixedly installed on the side wall of the upper guide rail 4.
