Description

Technical Field

[0001] The utility model relates to the technical field of drilling, in particular to a drilling mud sedimentation pumping device. Background Art

[0002] Drilling mud sedimentation is an important part of the drilling process, and its sedimentation effect directly affects the performance of the drilling fluid and the drilling efficiency.

[0003] In actual drilling operations, the sedimentation tank for drilling mud is usually a pit dug on site by an excavator, and then a plastic sheet is laid on the pit, resulting in the mud only being able to simply settle vertically in the tank, and the precipitated mud is not easy to be actively discharged, which is not conducive to personnel recovery and treatment.

[0004] The existing treatment of drilling mud has the following drawbacks: the existing drilling mud can only be directly discharged into the pit formed by the plastic sheet, and the mud cannot be precipitated and treated in an up-and-down staggered manner, resulting in poor recyclability of the mud. To this end, we propose a drilling mud sedimentation and drainage device. Summary of the invention

[0005] The main purpose of the utility model is to provide a drilling mud sedimentation pumping device, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A drilling mud sedimentation and pumping device comprises a mud storage tank, a lower baffle and an upper baffle, and also comprises a spiral rod and a guide base. The lower baffles are welded to the bottoms of both ends of the mud storage tank, the upper baffle is located between the lower baffles, the upper baffle is welded to the mud storage tank, a guide base is provided in the mud storage tank and at the bottom of the upper baffle, the bottom of the guide base is welded to the mud storage tank, a mud discharge groove is provided in the middle of the guide base, the spiral rod is located in the mud discharge groove, and an upper cover is provided on the top of the mud storage tank.

[0008] Furthermore, both ends of the spiral rod are rotatably connected to the mud storage tank through bearings.

[0009] Furthermore, a motor is installed at the bottom of one side of the mud storage tank through bolts, and the driving end of the motor is installed and connected to the rotating shaft of the spiral rod.

[0010] Furthermore, a mud discharge port is provided at the bottom of the other side of the mud storage tank, and a protective cover is installed at the end of the mud discharge port by bolts.

[0011] Furthermore, a drain outlet is provided at the bottom of one end of the mud storage tank, and a submersible pump is provided at the other end of the mud storage tank, and a discharge end of the submersible pump is connected to one end of the top of the upper cover.

[0012] Compared with the prior art, the utility model has the following beneficial effects: through the components consisting of the mud storage pool, the lower baffle, the upper baffle, the spiral rod and the guide base, the sedimentation and pumping treatment of the mud generated by drilling can be achieved, so that the silt in the mud can be precipitated and filtered by flowing up and down, so that the mud can be better recycled, and at the same time, the precipitated mud can be discharged to the outside autonomously in a spiral shape, which helps the drilling personnel to better collect the mud, and solves the problem that the existing drilling mud can only be directly discharged into the pit formed by the plastic cloth, and the mud cannot be precipitated up and down in an interlaced manner, resulting in poor recyclability of the mud.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-4 As shown, a drilling mud sedimentation and pumping device includes a mud storage tank 1, a lower baffle 2 and an upper baffle 3, and also includes a spiral rod 6 and a diversion base 4. The lower baffle 2 is welded to the bottom of both ends of the mud storage tank 1, and the upper baffle 3 is located between the lower baffles 2. The upper baffle 3 is welded to the mud storage tank 1. A diversion base 4 is arranged in the mud storage tank 1 and at the bottom of the upper baffle 3. The bottom of the diversion base 4 is welded to the mud storage tank 1. A mud discharge groove 5 is arranged in the middle of the diversion base 4. The spiral rod 6 is located in the mud discharge groove 5. The top of the mud storage tank 1 is covered with an upper cover 11.

[0020] Wherein, both ends of the spiral rod 6 are rotatably connected to the mud storage tank 1 through bearings.

[0021] A motor 9 is installed at the bottom of one side of the mud storage tank 1 by bolts, and a driving end of the motor 9 is installed and connected to the rotating shaft of the screw rod 6 .

[0022] A mud discharge port 7 is provided at the bottom of the other side of the mud storage tank 1, and a protective cover 8 is installed at the end of the mud discharge port 7 by bolts.

[0024] It should be noted that the utility model is a drilling mud sedimentation and drainage device. When working, the drilling construction personnel will arrange the sedimentation and drainage mechanism of the present application on one side of the drilling well, place the submersible pump 10 in the drainage pit on one side of the drilling well mouth, and use the power supply components around the work site as the power supply of the electrical mechanism in the present application. During use, the submersible pump 10 will drain the mud generated by the drilling to one end of the mud storage tank 1. As the weight of the mud in the mud storage tank 1 increases, the mud in the mud storage tank 1 will settle into the mud discharge groove 5 at the bottom of the upper partition 3, and the light liquid will overflow to the drainage port 12 on one side of the lower partition 2, and be discharged to the outside through the drainage port 12. After the operation is completed, the personnel will open the protective cover 8, drive the screw rod 6 through the motor 9, and the screw rod 6 will spirally discharge the precipitated mud through the mud discharge port 7, so as to complete the complete drilling mud sedimentation and drainage treatment, so that the mud can be recycled, and the liquid can be recirculated for drilling lubrication.
