Description

Technical Field

[0001] This utility model relates to the field of mud conveying equipment technology, and more specifically, to a slurry pump assembly with mud conveying function. Background Technology

[0002] The content in this section only provides background information related to this utility model and may not constitute prior art.

[0003] After drilling operations for resources such as oil, natural gas, and coalbed methane are completed, a large amount of waste drilling mud will remain at the well site. This mud plays a crucial role in the drilling process, such as carrying rock cuttings, cooling the drill bit, and balancing formation pressure. However, its composition is complex, usually consisting of a mixture of water, clay, chemical treatment agents, and drill cuttings. It has the characteristics of high water content, high viscosity, high suspended solids content, and may contain harmful substances.

[0004] With increasingly stringent global environmental regulations and the growing adoption of green operating principles, efficient and compliant treatment and disposal of waste drilling mud has become an indispensable key aspect of drilling engineering. Against this backdrop, it is necessary to solidify, separate, dewater, or transport the mud to specialized treatment facilities. Among these processes, centralized transfer and transportation of the mud is the first step in the treatment process.

[0005] However, the relevant technology has the following drawbacks. In actual use, because the mud contains a large number of complex components, it is very easy to cause blockage in the input and output pipes of the slurry pump. It is necessary to replace the input and output pipes from time to time. However, the traditional pipe replacement speed is slow. In actual use, it is usually necessary to stop the entire equipment for too long, which has an adverse effect on construction efficiency. Utility Model Content

The through pipe is plugged into a connecting section, and an installation groove is provided on the connecting section.

[0011] In some possible embodiments, a connecting block is fixedly provided at one end of the connecting segments that are far apart from each other. A connecting hole is provided on the connecting block, and the connecting hole communicates with the limiting hole. The diameter of the connecting hole is less than or equal to that of the limiting hole. A push rod is slidably provided in the connecting hole, and the bottom end of the push rod is used to abut against the top end of the limiting member.

[0012] In some possible embodiments, a second elastic element is provided on the connecting block, and a boss is coaxially fixedly provided on the top end of the push rod. The diameter of the boss is larger than that of the push rod. The second elastic element is sleeved on the push rod, and the bottom end of the second elastic element is fixedly connected to the top of the connecting block, and the other end is fixedly connected to the bottom of the boss.

[0013] In some possible embodiments, the end of the limiting member is fitted with a ball bearing for rolling contact with the inner wall of the mounting groove.

[0014] In some possible embodiments, an abutment sleeve is slidably disposed inside the connecting section, the end of the abutment sleeve being used to abut against the end of the through pipe, and a third elastic member is disposed on the connecting section, the third elastic member being used to drive the abutment sleeve to move toward the through pipe.

[0015] In some possible embodiments, a groove is provided on the inner wall of the connecting section, a slider is slidably disposed in the groove, a third elastic member is disposed in the groove, one end of the third elastic member is fixedly connected to the side wall of the slider away from the through pipe, and the other end is fixedly connected to the inner wall of the groove, and the abutment sleeve completely covers the bottom opening of the groove.

[0016] In summary, the technical solution of this utility model embodiment has at least the following advantages and beneficial effects:

[0017] 1. The detachable connecting pipe design allows for rapid pipe replacement when slurry pumps become clogged. The connecting pipe consists of a connecting section and an extension section, and is fixed to the pump body by limiting components. This modular structure allows operators to directly replace the clogged section without disassembling the entire pump body. Compared to traditional welded or bolted pipes, this design eliminates complex disassembly steps and significantly shortens maintenance time.

[0018] 2. The system adopts a plug-in connection method between the pipe and the connecting section, and achieves precise positioning through the sliding cooperation of the mounting block and the mounting groove. The limiting component automatically engages with the limiting hole under the action of the elastic component, ensuring the stability of the connecting pipe under the impact of high-pressure mud and preventing accidental detachment. Furthermore, the combination of the abutment sleeve and the third elastic component achieves dynamic sealing at the pipe interface. Under the action of elastic force, the abutment sleeve always fits tightly with the end of the pipe, effectively preventing mud leakage. At the same time, it buffers the vibration and pressure fluctuations during the transportation process, improving the durability and operational safety of the components, and is suitable for long-term use under harsh working conditions.

[0019] 3. A push rod and a second elastic element are installed on the connecting section, making the disassembly process simpler. When the pipeline needs to be replaced, the operator only needs to press the push rod to lift the limit pin through the lever principle and release the fixed state. No special tools or complicated operations are required. The ball embedded at the end of the limit element rolls in contact with the inner wall of the installation groove, reducing the frictional resistance during installation and making the insertion and removal process smoother. This significantly reduces the skill requirements and physical exertion of maintenance personnel. Especially in complex environments such as well sites, pipeline replacement can be completed quickly, reducing human error and improving the overall efficiency of maintenance work.

[0020] 4. The self-adaptive connection of the pipeline is achieved through multiple elastic elements and movable structures. The abutment sleeve can be finely adjusted in position when the mud pressure changes, maintaining a tight fit with the pipe and avoiding seal failure due to wear. The design of the groove and slider allows the abutment sleeve to move flexibly in the axial direction, compensating for installation errors and thermal expansion and contraction effects, extending the service life of the pipeline and pump body. This allows the components to adapt to mud of different viscosities and compositions, reducing the frequency of replacement due to blockage or wear. In the long run, this reduces equipment maintenance costs and resource waste, and meets the requirements of environmentally friendly operations. Attached Figure Description
