Description

Technical Field

[0001] This utility model relates to the technical field of mud conveying equipment, and more specifically, to a mud cleaning and conveying device after drilling. 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, the efficient and compliant treatment and disposal of waste drilling mud has become an indispensable and crucial aspect of drilling engineering. In this context, it is necessary to solidify, separate, dewater, or transport the mud to specialized treatment facilities. 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, in order to minimize the probability of mud clogging the transport pipeline, it is usually necessary to clean and dilute the mud. During this process, workers usually spray the mud in the transport process with a handheld spray pipe. However, this places a heavy workload on the workers during long working hours. Utility Model Content

[0006] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a post-drilling mud cleaning and conveying device that can reduce the workload of workers.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A post-drilling mud cleaning and conveying device includes a frame, a conveying component mounted on the frame, a mounting frame mounted on the frame, a mounting part slidably mounted on the mounting frame perpendicular to the conveying direction, a sprayer mounted on the mounting part, a driving component mounted on the mounting frame for driving the mounting part to move on the mounting frame, and a dispersing component mounted on the mounting frame for stirring and dispersing the conveyed mud.

[0009] In some possible embodiments, the bottom of the mounting bracket is provided with a groove perpendicular to the conveying direction, a slider is slidably disposed in the groove, a connecting block is fixedly disposed at the bottom of the slider, the mounting part is fixedly connected to the bottom of the connecting block, and the driving component is used to drive the slider to move in the groove.

[0010] In some possible embodiments, the drive assembly includes a drive member and a drive rod. The drive member is fixedly mounted on the mounting bracket, and the drive rod is rotatably mounted in a groove. The drive rod has two helical grooves with opposite directions of rotation along its length. The two helical grooves are interconnected. The slider is threaded onto the drive rod, and the output end of the drive member is connected to the drive rod in a transmission manner.

[0011] In some possible embodiments, the groove is formed as a T-shaped groove, and the slider is configured as a T-shaped block adapted to the groove.

[0012] In some possible embodiments, ball bearings are embedded in the sidewalls of the slider, the ball bearings being used to roll into contact with the inner wall of the groove.

[0013] In some possible embodiments, the dispersing assembly includes a dispersing roller and a drive source, the dispersing roller being rotatably disposed at the end of the mounting frame, the drive source being used to drive the dispersing roller to rotate, and a plurality of dispersing rods being fixedly disposed on the surface of the dispersing roller.

[0014] In some possible embodiments, the mounting bracket has an observation hole covered by a cover plate, the cover plate is detachably connected to the mounting bracket, and the cover plate is provided with a limiting member for limiting the position of the cover plate on the mounting bracket.

[0015] In some possible embodiments, the limiting member is set as a limiting bolt, the cover plate has four mounting holes, which are located at the four corners of the cover plate, and the mounting bracket has limiting holes for threaded connection of the limiting bolt. The position and number of the limiting holes are adapted to the mounting holes.

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

[0017] 1. The drive assembly drives the installation unit to slide on the mounting frame perpendicular to the conveying direction, enabling the sprayer to automatically cover the entire width of the mud conveying area. This eliminates the need for manual operation by personnel holding the spray pipe, avoiding fatigue and health problems caused by prolonged repetitive labor. It also improves the continuity and stability of the operation. Compared with traditional manual spraying, this device not only reduces the manpower required but also ensures the uniformity and consistency of the spraying process, thereby improving the overall efficiency and quality of mud cleaning.

[0018] 2. The dispersion component includes a dispersion roller and a drive source. Several dispersion rods are fixed on the surface of the dispersion roller, which can actively stir the mud during the conveying process, so that the solid particles and viscous substances in the mud are fully dispersed, avoiding agglomeration and sedimentation. This increases the contact area between the spray water and the mud, improves the dilution and cleaning effect, and improves the fluidity of the mud through mechanical stirring, reducing the risk of blockage during the conveying process, while ensuring the smooth progress of subsequent processing steps.

[0019] 3. Two spiral grooves with opposite directions of rotation are opened on the drive rod. The slider is threaded onto the drive rod, which enables the sprayer to reciprocate linearly along the groove, realizing the automatic control of the sprayer. The symmetrical design of the spiral grooves also ensures the smoothness and uniformity of the movement, avoiding the problems of spray dead corners or local over-spraying. The groove is set as a T-shaped groove, and the slider is matched as a T-shaped block with embedded ball bearings, which further reduces friction and wear, extends the service life of the equipment, and ensures the comprehensiveness and consistency of the spray coverage.

[0020] 4. An observation hole is provided on the mounting frame and covered with a cover plate. The cover plate is detachably connected to the mounting frame through a limiting component, which allows the staff to easily check the working status and wear of the internal components. This simplifies the daily maintenance and troubleshooting process. Partial repairs or replacements can be performed without disassembling the entire device, greatly reducing downtime and maintenance costs. The observation hole provides a window for real-time monitoring of the mud washing process, which helps to adjust operating parameters in a timely manner, ensuring that the equipment is always in the best operating condition, and improving the overall reliability and operability.
