Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to an oil-based drilling fluid cuttings cleaning device. Background Art

[0002] For a long time, sand washing in geological logging has been a simple yet arduous labor. Sand bailers place a sand collection basin downstream of the drilling fluid vibrating screen. Drill cuttings are shaken off the vibrating screen and fall into the basin. After a predetermined delay, the bailers carry the collected sand to a large water tank, rinse it with water, and repeatedly stir it with a stirring rod. If the water becomes dirty, the bailers pour it out and then add clean water to rinse it. This process is repeated until the cuttings are clean and then placed in a designated location for the next step.

[0003] When cleaning drill cuttings from oil-based drilling fluid, the drill cuttings containing oil stains are first placed in a cleaning tank, and an appropriate amount of cleaning liquid is added and stirred so that the chemicals in the cleaning liquid react with the oil stains to remove them from the surface of the drill cuttings. However, the cleaning tank will contain a large amount of solid particles from the drill cuttings, which may clog pipes or valves, causing the cleaning device to malfunction, thereby affecting the normal cleaning of the drill cuttings. Therefore, the present application proposes an oil-based drilling fluid drill cuttings cleaning device. Utility Model Content

[0029] Example

[0030] like Figure 1 As shown, the oil-based drilling fluid cuttings cleaning device proposed in the utility model includes a base plate 1 and a cleaning tank 2 fixedly installed on the top of the base plate 1. Drill cuttings can be placed in the cleaning tank 2 for cleaning. A collection tank 3 is provided on the top of the base plate 1 on one side of the cleaning tank 2. The collection tank 3 is used to collect solid particles in the drill cuttings.

[0031] In addition, a fixed block 4 is provided on one side of the top of the base plate 1. The fixed block 4 is rectangular and vertically installed on the base plate 1. A slide groove 5 is provided on one side of the fixed block 4. A water inlet pipe 23 is fixedly installed on one side of the cleaning pool 2, and a sewage pipe 24 is fixedly installed on the other side of the cleaning pool 2. Valves are provided on both the water inlet pipe 23 and the sewage pipe 24, and the water inlet of the water inlet pipe 23 and the drainage of the sewage pipe 24 are controlled by the valves.

[0032] like Figure 1 and Figure 2 As shown, the device also includes a filtering device, which is arranged in the cleaning tank 2 and is used to filter solid particles in the drill cuttings in the cleaning tank 2. The filtering device includes a filter frame 20 arranged in the cleaning tank 2. The bottom inner wall of the filter frame 20 is provided with a square groove, and the inner wall of the square groove is clamped with a filter screen 21. The filter screen 21 is used to filter solid particles in the salvaged drill cuttings. The inner wall of the filter frame 20 is installed with a stirring rod 22.

[0033] In addition, the stirring rod 22 is provided with multiple groups of stirring blades, and the output shaft of the stirring rod 22 is connected to a motor, which controls the stirring operation of the stirring rod 22 so that the cleaning liquid and the drill cuttings are fully contacted and mixed. A connecting plate 12 is fixedly mounted on one side of the filter frame 20, and the connecting plate 12 is connected to a moving device;

[0034] Furthermore, the moving device includes a slider 6 slidably mounted in the chute 5, a support rod 7 is fixedly mounted on the slider 6, a mounting plate 9 is fixedly connected to the support rod 7, a rotating shaft 10 is rotatably mounted on the mounting plate 9, a connecting member 11 is fixedly mounted on the rotating shaft 10, and the connecting member 11 is fixedly connected to the connecting plate 12. The connecting plate 12 can be driven to slide up and down by the slider 6, so that the filter frame 20 can be moved up and down for adjustment;

[0035] It is worth noting that a screw rod 18 threadedly connected to the slider 6 is rotatably installed in the chute 5, and a drive motor 19 is fixedly installed on the top of the fixed block 4. The output shaft of the drive motor 19 is fixedly connected to the screw rod 18. When the drive motor 19 is started, the screw rod 18 rotates, and the slider 6 drives the filter frame 20 to move upward, so that the filter frame 20 is separated from the cleaning tank 2, and the filter screen 21 successfully filters and salvages the solid particles in the drill cuttings.

[0036] Furthermore, a motor 8 is fixedly mounted on one side of the mounting plate 9. The output shaft of the motor 8 is fixedly connected to the rotating shaft 10. When the motor 8 is started, the rotating shaft 10 can be rotated. The rotation of the rotating shaft 10 causes the filter frame 20 to be rotated and adjusted, so that the filter screen 21 is tilted, which facilitates the cleaning of solid particles and filter residue salvaged from the filter screen 21.

[0037] It is worth mentioning that a horizontal plate 16 is fixedly installed on the top of the base plate 1, and a sliding plate 17 is slidably installed on the horizontal plate 16. The sliding plate 17 is fixedly connected to the fixed block 4. A support plate 13 is fixedly installed on the top of the base plate 1 on one side of the fixed block 4. An electric push rod 14 is fixedly installed on the support plate 13. A connecting block 15 fixedly connected to the fixed block 4 is installed on the electric push rod 14. The fixed block 4 is driven to move forward and backward by the push of the electric push rod 14. With the support of the sliding plate 17, the fixed block 4 drives the filter frame 20 to move forward.

[0038] like Figure 1 and Figure 3As shown, the device also includes a scraping device, which is arranged in the collection tank 3 for automatically cleaning and collecting solid particles filtered on the filter device. The scraping device includes a rocker 25 rotatably installed on one side of the inner wall of the collection tank 3, and a support bar 26 is connected to the rocker 25. The support bar 26 is provided with an electric slide rail 27, and a scraper 28 is slidably installed on the electric slide rail 27. According to the rotation adjustment of the filter frame 20, the rocker 25 is shaken to make the support bar 26 and the filter screen 21 tilt at the same angle. The electric slide rail 27 is used to enable the scraper to scrape back and forth to clean the filter residue and solid particles accumulated on the filter screen 21, thereby improving the filtering effect.

[0039] Working principle: By starting the drive motor 19, the screw rod 18 rotates, and the slider 6 drives the connecting plate 12 to move up together, further making the filter frame 20 move up until it leaves the cleaning tank 2, so that the filter screen 21 can filter and salvage the filter residue and solid particles of drill cuttings in the cleaning tank 2, and then use the push of the electric push rod 14 to make the sliding plate 17 drive the fixed block 4 to move forward, driving the filter frame 20 to move toward the collection tank 3, starting the motor 8, and rotating the shaft 10 to drive the filter frame 20 to rotate and tilt, so that the filter screen 21 is tilted at a certain angle, and then the inclination of the support bar 26 is adjusted to be consistent with the filter screen 21 by shaking the rocker 25, and then the electric slide rail 27 is used to make the scraper rod 28 scrape the filter residue and solid particles accumulated on the filter screen 21 back and forth, thereby completing the automatic cleaning of the filter screen 21, significantly improving the filtering effect.

[0040] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
