Therefore, they should not be construed as limitations on this utility model.
[0028] like Figures 1-7As shown, this utility model provides a technical solution: a green exploration drum mud treatment device, including a working face 1, which in this application refers to the ground. The separation tank 5, sedimentation tank 4, hydrocyclone 6, and circulation tank 7 are all placed on the ground. The sedimentation tank 4 and circulation tank 7 are not obtained by excavating the ground, but exist as boxes. In this embodiment, the whole adopts a modular design. By utilizing the cooperation between the components, it is possible to separate impurities such as rock cuttings in the mud and recycle the mud. The components are connected by pipes, and the pipes are equipped with flow meters and valves to control the mud flow. The separation tank 5 is located at the top of the working face 1 and is used to separate rock cuttings in the mud. The sedimentation tank 4 is set on the left side of the separation tank 5. The sedimentation tank 4 has an open top structure. The hollow pipe 2 is set on the left side of the sedimentation tank 4. The drill rod 3 is set inside the hollow pipe 2. The hydrocyclone 6 is set on the right side of the separation tank 5. The circulation tank 7 is set on the right side of the hydrocyclone 6. The circulation tank 7 is used to provide a mud discharge site.
[0029] like Figure 1-7As shown in the embodiment of this application, a circular ring 509 is provided at the bottom inner side of the separating tank 5, and a fixing ring 510 is provided on the outer wall of the circular ring 509. A scraper 506 is arranged in a circumferential array on the outer edge of its top, and a mud filter 501 is provided at the center of the top. A circular plate 508 is provided on the top of the scraper 506, and a fixing shaft 507 is provided on the inner side of the circular plate 508. The fixing shaft 507 extends through to the top of the separating tank 5 and is connected to the motor output end. Specifically, the separating tank 5 is located at the top of the working surface 1, and a fixing ring 501 is fixedly provided on its inner wall near the bottom. Ring 510, with a circular ring 509 rotatably mounted on its outer wall. A scraper 506 and a mud filter screen 501 are fixedly mounted on the top of the circular ring 509. A circular plate 508 is fixedly connected to the top of the scraper 506, and the circular plate 508 is fixedly mounted on the outer wall of a fixed shaft 507. The fixed shaft 507 is connected to the output end of a motor. When the motor is started, it drives the fixed shaft 507 to rotate. Simultaneously, the rotation of the fixed shaft 507 drives the circular plate 508 to rotate, which in turn drives the scraper 506 to rotate along the inner wall of the separator 5. To prevent the slurry mixture from adhering to the inner wall of the separator 5, the inner wall of the separator 5 is polished. As the scraper 506 rotates, the ring 509 drives the slurry filter 501 to rotate. The top of the slurry filter 501 is rounded. The scraper 506 has a triangular cross-section, with its apex facing the centerline of the separator 5. The apex is rounded to allow the slurry mixture to slide off the side of the scraper 506 as it rotates along the inner wall of the separator 5, preventing material accumulation on the scraper 506 itself. The bottom corners are not rounded. The mud filter screen 501 forms a sharp edge with the inner wall of the separator 5, cutting into the mud mixture adhering to the inner wall of the separator 5. The concentrated contact pressure effectively breaks the adhesion between the mud mixture and the inner wall of the separator. The stable geometric structure of the triangle makes it have high bending strength and is not prone to bending deformation. When the mud enters the separator 5, the mud filter screen 501 filters the rock debris and allows the mud to enter the hydrocyclone 6. During the rotation, the mud filter screen 501 rotates synchronously, which can throw off the rock debris.
[0030] like Figure 1-7As shown in the embodiment of this application, one end of the hollow tube 2 is placed in the borehole below the working face 1, and the other end is placed above the working face 1. The hollow tube 2 is equipped with a drill rod 3, and its outer wall is connected to a diversion pipe 201. The outlet end of the diversion pipe 201 is located above the sedimentation tank 4. Specifically, after the drilling machine is stopped at the predetermined hole position, it is drilled. After the hole is drilled, the hollow tube 2 is lowered into the borehole, and the gap between the hollow tube 2 and the borehole is sealed tightly by grouting, which can effectively prevent mud leakage and facilitate the recycling of mud. After the drill rod 3 of the drilling machine passes through the hollow tube 2, drilling is carried out. At the same time, the mud in the circulation tank 7 is injected into the drilling machine through the mud inlet of the drilling machine. Then, the mud overflows from the gap between the drill rod 3 and the hollow tube 2 and is discharged into the sedimentation tank 4 through the diversion pipe 201 for preliminary filtration.
[0031] like Figures 1-7 As shown in the embodiment of this application, a groove is provided at the top of the sedimentation tank 4, and a mud screen 401 is installed in the groove. A first discharge pipe 404 is provided on the bottom right side of the groove. The first discharge pipe 404 is connected to a first pump body 402, and the first pump body 402 is connected to a first feed pipe 403. Specifically, the groove at the top of the sedimentation tank 4 is used to house the mud screen 401, facilitating its assembly and disassembly. The mud screen 401 is in the shape of a limiting inverted trapezoid. When the mud enters the sedimentation tank 4, it first passes through the mud screen. Screen 401 is used for filtration to separate rock cuttings and mud. When the mud screen 401 is about to become clogged, it is removed from the top of the sedimentation tank 4 and rinsed with a high-pressure water gun to prevent the screen from becoming clogged. A first discharge pipe 404 is fixedly connected to the right side of the sedimentation tank 4. The first discharge pipe 404 is connected to the suction end of the first pump body 402, while the first feed pipe 403 is connected to the discharge end of the first pump body 402. Under the action of the first pump body 402, the mud in the sedimentation tank 4 is transported to the separation tank 5 for secondary filtration.
[0032] like Figures 1-7 As shown in the embodiment of this application, one end of the first feed pipe 403 is connected to the separation tank 5. A first drain pipe 502 is provided on the front side of the separation tank 5, and a second discharge pipe 503 is provided at its bottom. The second discharge pipe 503 is connected to the second pump body 504. The second pump body 504 is connected to the second feed pipe 505. The other end of the second feed pipe 505 is connected to the hydrocyclone 6. Specifically, the mud flowing into the separation tank 5 is separated from the rock cuttings. The rock cuttings are discharged from the first drain pipe 502. In this application, the drain pipes are all connected to valves. The mud is drawn out of the separation tank 5 by the action of the second pump body 504 and transported to the hydrocyclone 6 along the second discharge pipe 503 and the second feed pipe 505 for the third separation operation.
[0033] like Figures 1-7As shown in the embodiment of this application, a second drain pipe 601 is provided at the bottom of the hydrocyclone 6, and a third feed pipe 602 is provided at the top right side of the hydrocyclone 6. The other end of the third feed pipe 602 is connected to the circulation tank 7. Specifically, the hydrocyclone 6 performs a third filtration of the mud. Since the hydrocyclone 6 is existing technology, it will not be described in detail here. The mud in the hydrocyclone 6 flows into the circulation tank 7 from the third feed pipe 602 at the overflow port, while the rock debris is discharged from the second drain pipe 601 at the bottom.
[0034] like Figures 1-7 As shown in the embodiment of this application, a fourth discharge pipe 701 is provided on the right side of the circulation tank 7. The fourth discharge pipe 701 is connected to the fourth pump body 702. The fourth pump body 702 is connected to the fourth feed pipe 703. The other end of the fourth feed pipe 703 is connected to the mud inlet of the drilling rig. Specifically, the mud after three filtrations is driven by the fourth pump body 702 in the circulation tank 7, and flows to the mud inlet of the drilling rig through the fourth discharge pipe 701 and the fourth feed pipe 703, so that the mud can be recycled.
[0035] The working principle of this utility model is as follows:
[0036] After the drilling rig is positioned at the designated hole location, it is drilled. Once the hole is drilled, the hollow tube 2 is lowered into the borehole, and the gap between the hollow tube 2 and the borehole is sealed tightly by grouting. This effectively prevents mud leakage and facilitates mud recycling. The drill rod 3 of the drilling rig is then inserted through the hollow tube 2 for drilling operations. Simultaneously, mud from the circulation tank 7 is injected into the drilling rig through the mud inlet. The mud then overflows from the gap between the drill rod 3 and the hollow tube 2 and is discharged through the diversion pipe 201 to the sedimentation tank 4 for preliminary filtration. The mud screen 401 in the sedimentation tank 4 can isolate large rock cuttings. The mud filtered from the sedimentation tank 4 will be discharged from the first discharge pipe 404 and driven by the first pump body 402 to the first feed pipe 403. The mud is transported to the separation tank 5 for secondary filtration. The motor is started, and the motor drives the fixed shaft 507 to rotate. While the fixed shaft 507 rotates, it drives the scraper 506 at the bottom of the circular plate 508 to rotate. During the rotation of the scraper 506, the mud filter screen 501 rotates, thereby filtering the mud. The mud after secondary filtration is discharged from the second discharge pipe 503 and is driven by the second pump body 504 to be transported to the second feed pipe 505, thereby entering the hydrocyclone 6 for tertiary filtration. The separated rock cuttings are discharged from the first drain pipe 502. The mud is finely separated in the hydrocyclone 6. The rock cuttings are discharged from the second drain pipe 601 at the bottom of the hydrocyclone 6. The separated mud enters the circulation tank 7 from the third feed pipe 602. The mud in the circulation tank 7 is transported to the mud inlet of the drilling rig through the fourth discharge pipe 701, the fourth pump body 702, and the fourth feed pipe 703, and is reused for drilling, realizing the recycling of mud.
[0037] In summary, this utility model discloses a green exploration drum mud treatment device, including a separation tank 5 located at the top of the working face 1 for separating rock cuttings from the mud. A sedimentation tank 4 with an open top is located on the left side of the separation tank 5. A hollow tube 2 is located on the left side of the sedimentation tank 4, and a drill pipe 3 is installed inside the hollow tube 2. A hydrocyclone 6 is located on the right side of the separation tank 5, and a circulation tank 7 is located on the right side of the hydrocyclone 6, providing a mud discharge location. This utility model employs a three-stage treatment process—sedimentation tank, separation tank 5, and hydrocyclone 6—to achieve deep purification of the mud, facilitating its recycling. Simultaneously, the separated rock cuttings can be centrally processed, avoiding environmental pollution. After filtration, the proportion of rock cuttings in the mud is reduced, thereby reducing wear on the drill bit, increasing drill bit lifespan, and improving drilling efficiency.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
