Description

Technical Field

[0001] This utility model relates to the field of mud circulation tank technology, specifically a mud circulation tank for drilling operations. Background Technology

[0002] Drilling mud generally refers to drilling fluid, a general term for various circulating fluids used in the drilling process to meet the needs of drilling operations. Drilling mud contains various additives and some soluble heavy metals. Therefore, when drilling mud is stored in a mud circulation tank, some heavy metals will precipitate on the inner wall of the tank. If workers enter the mud circulation tank to handle these materials, it will pose a health hazard. Therefore, improvements are needed to address this issue.

[0003] As disclosed in the utility model patent with authorization announcement number CN4704468U, a mud circulation tank that is easy to clean is provided. It adds a stirring structure to the mud circulation tank, thereby using the principle of stirring to prevent the sedimentation of drilling mud and solve the problem of sediment accumulation on the inner wall of the mud circulation tank caused by sedimentation. However, the stirring of this device is not uniform during the stirring process. Therefore, after long-term use, the device will still accumulate mud sediment with the increase of the number of uses. It is inevitable that sediment will adhere to the inner wall of the tank. After adhesion, it is impossible to guarantee that it will always be clean, which will affect the efficiency of mud circulation during the mud circulation process. Therefore, we propose a mud circulation tank for drilling construction. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a mud circulation tank for drilling operations that can mix the mud evenly and prevent sedimentation, thus effectively solving the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drilling mud circulation tank, comprising a tank body and an actuating assembly;

[0006] A first motor is installed at the right end of the tank body, and an actuating assembly is installed at the upper end of the circumferential surface of the tank body. The input end of the first motor is electrically connected to the output end of an external control switch group.

[0007] The actuation assembly includes a mounting strip, a second motor, a turntable, a pull strip, a fixing strip, and guide frames. The mounting strip is fixed to the upper end of the circumferential surface of the tank. The second motor is mounted on the rear side of the mounting strip. The turntable is fixed to the output shaft of the second motor. The pull strip is rotatably connected to the edge of the turntable. A groove is provided on the left side of the fixing strip. The right end of the pull strip is riveted into the groove. All connecting strips are fixed to the lower side of the fixing strip. Evenly distributed guide frames are fitted onto the side of the fixing strip. All guide frames are fixed to the circumferential surface of the tank. The input end of the second motor is electrically connected to the output end of an external control switch group.

[0008] Furthermore, an injection hole is provided at the upper right end of the circumferential surface of the tank body, and a feed pipe is fixed inside the injection hole, through which the slurry is injected into the interior of the tank body.

[0009] Furthermore, a discharge pipe is fixed inside the discharge port located at the left end of the tank, and a sealing cap is fastened to the left end of the discharge pipe, through which the stirred slurry is discharged.

[0010] Furthermore, the tank is provided with multiple units, and the top discharge pipe is connected to a high-efficiency cleaner via a pipeline. A vacuum degasser is connected to one side of the high-efficiency cleaner via a pipeline. A grouting pump is connected to one side of the vacuum degasser via a pipeline. A weight-bearing pump is connected to one side of the grouting pump via a pipeline. A shear pump is connected to one side of the shear pump via a pipeline. A medium-speed centrifuge is sequentially arranged on one side of the medium-speed centrifuge. A high-speed centrifuge and an ultra-high-speed centrifuge are arranged inside the medium-speed centrifuge, high-speed centrifuge, and ultra-high-speed centrifuge. A stirrer is installed inside each of the medium-speed centrifuge, high-speed centrifuge, and ultra-high-speed centrifuge. A mechanical liquid level alarm is fixed on the outer wall of each of the medium-speed centrifuge, high-speed centrifuge, and ultra-high-speed centrifuge. A centrifuge oil supply pump is installed on the side wall of each of the medium-speed centrifuge, high-speed centrifuge, and ultra-high-speed centrifuge.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This drilling mud circulation tank has the following advantages:

[0012] The mud is stored in a tank. After injection, the mud moves to the left along the tank. During this movement, a second motor is activated to rotate the turntable. The rotation of the turntable drives the pulling bar to move, which in turn drives the installation bar to move back and forth. This further agitates the mud, effectively preventing sediment from forming and adhering to the inner wall of the tank, thus maintaining a clean state and making the mud circulation more efficient.

The mounting strip 61 is fixed to the upper end of the circumferential surface of the tank body 1. The second motor 62 is mounted on the rear side of the mounting strip 61. The turntable 63 is fixed to the output shaft of the second motor 62. The pull strip 64 is rotatably connected to the edge of the turntable 63. A groove is formed on the left side of the fixing strip 65, and the right end of the pull strip 64 is riveted into the groove. All connecting strips 44 are fixed to the lower side of the fixing strip 65. Evenly distributed guide frames 66 are fitted onto the side of the fixing strip 65, and all guide frames 66 are fixed to the circumferential surface of the tank body 1. The input end of the second motor 62 is electrically connected to the output end of an external control switch group.

[0020] Wherein: A material injection hole is opened at the upper end of the right side of the circumferential surface of the tank body 1, and a feed pipe 7 is fixed inside the material injection hole. The mud is injected into the interior of the tank body 1 through the feed pipe 7.

[0021] Among them: the discharge port set at the left end of the tank body 1 is equipped with a discharge pipe 8, and the left end of the discharge pipe 8 is fastened with a sealing cap 9. The stirred mud is discharged through the discharge pipe 8.

[0022] The tank 1 is equipped with multiple units, and the top discharge pipe 8 is connected to a high-efficiency cleaner 11 via a pipeline. A vacuum degasser 12 is connected to one side of the high-efficiency cleaner 11 via a pipeline. A grouting pump 13 is connected to one side of the vacuum degasser 12 via a pipeline. A weight-reinforcing pump 14 is connected to one side of the grouting pump 13 via a pipeline. A shear pump 15 is connected to one side of the weight-reinforcing pump 14 via a pipeline.

After injection, the mud moves to the left along the tank body 1. During its movement, the second motor 62 is started to make the turntable 63 rotate. The rotation of the turntable 63 drives the pulling bar 64 to move. The movement of the pulling bar 64 drives the fixing bar 65 to move back and forth. The left and right reciprocating movement of the fixing bar 65 further agitates the mud, thereby effectively preventing the formation of sediment. This prevents sediment from adhering to the inner wall of the tank body 1, thus keeping it clean and making the mud circulation more efficient. The agitated mud is discharged through the discharge pipe 8 and can continue to circulate.
