Technical Field
[0001] This utility model relates to the field of drilling platform mud and wastewater treatment technology, and in particular to a mud and wastewater collector. Background Technology
[0002] In drilling operations, drilling mud is an essential tool used to cool the drill bit, remove drilling waste, and stabilize the wellbore. However, as drilling progresses, wastewater and drilling mud are not effectively treated, which not only pollutes the surrounding environment but also wastes resources, a common problem on drilling platforms.
[0003] Existing technologies, such as the utility model patent with publication number CN205823239U, disclose a solid-liquid four-phase separation device for drilling waste. This patent includes an oscillator, a cuttings conveying device, a mud separator, a mud collection tank, a settling tank, an oil-water separator, and a circulating spray unit. The mud separator includes a housing, a centrifuge tank, a motor, a partition plate, and a support platform. The bottom of the centrifuge tank is connected to the mud collection tank via a mud collection pipe. The settling tank is connected to a wastewater tank via a wastewater collection pipe, and its bottom is connected to the mud collection tank via a discharge pipe. The bottom of the settling tank is also connected to the oil-water separator via a return pipe. The oil-water separator is equipped with an oil discharge pipe and a water discharge pipe. The circulating spray unit includes a circulating pump, a circulating water pipe, and spray heads. This utility model can effectively separate drilling cuttings, drilling mud, drilling wastewater, and sludge from drilling waste, improving environmental protection.
[0004] It has been found on drilling platforms that during drilling operations, the amount of solid particles and other pollutants in the drilling mud gradually increases, forming a mixture of sewage and mud. After the mud and sewage are mixed, their composition becomes more complex, containing solid particles from the mud and harmful chemicals from the sewage. This will increase the burden on the sewage treatment equipment on the drilling platform, leading to increased wear and tear and maintenance frequency. Utility Model Content
[0005] The purpose of this invention is to address the problem in the existing technology that, during drilling operations, the amount of solid particles and other pollutants in the drilling mud gradually increases, forming a mixture of sewage and drilling mud. After the mud and sewage are mixed, their composition becomes more complex, containing solid particles from the drilling mud and harmful chemicals from the sewage. This will increase the burden on the sewage treatment equipment on the drilling platform, resulting in increased wear and tear and maintenance frequency.
[0006] To solve the above-mentioned technical problems, this utility model provides a mud and sewage collector, comprising: a connecting pipe, a drill rod disposed inside the connecting pipe, a collecting device disposed on the arc surface of the connecting pipe, the collecting device comprising a mud collecting component, a sewage collecting component, a filtering component, and a fixing component, the mud collecting component disposed on the upper arc surface of the connecting pipe, the sewage collecting component disposed on the lower arc surface of the connecting pipe, the filtering component disposed on the upper inner wall of the connecting pipe, a collecting umbrella cloth sleeved on the connecting pipe corresponding to the positions of the mud collecting component and the sewage collecting component, the mud collecting device comprising a mud fixing frame and a mud docking frame, the inner walls of the mud fixing frame and the mud docking frame abutting against the arc surface of the connecting pipe, the two end surfaces of the mud fixing frame and the mud docking frame being fixedly connected by the fixing component, the sewage collecting component comprising a sewage fixing frame and a sewage docking frame, the inner wall surfaces of the sewage fixing frame and the sewage docking frame being fixedly connected with sealing rings, the inner wall surfaces of the sealing rings abutting against the arc surface of the connecting pipe, the sewage fixing frame and the sewage docking frame being fixedly connected by the fixing component.
[0007] The aforementioned components achieve the following effects: by adding a mud collection assembly to the drill pipe face platform, truly efficient mud recovery is achieved, realizing effective separation, directional collection, and leakage prevention of mud and wastewater. By placing the mud collection assembly at the top of the connecting pipe and the wastewater collection assembly at the bottom, in conjunction with a filter assembly, gravity or centrifugal force is used to naturally separate the mud and wastewater. The collection umbrella and sealing ring work together to ensure a tight seal during the collection process, preventing splashing and leakage. The mud and wastewater collection assemblies adopt a separate fixing frame and docking frame design, connected by fixing components, facilitating installation, disassembly, and maintenance.
[0008] Preferably, the filter assembly includes a filter flange, the inner wall of which is fixedly connected to the upper surface of the connecting pipe, and the arc surface of the filter flange is provided with a plurality of connecting holes.
[0009] The aforementioned components achieve the following effects: the filter flange, as the core of the filter assembly, has its inner wall fixedly connected to the upper end of the connecting pipe, ensuring that the fluid must flow through this point. Multiple connecting holes on the flange's arc surface allow the mud-containing mixture to pass through and enter the mud collection area, while simultaneously providing preliminary filtration. This prevents excessively large particles or debris from entering the collector with the mud, protecting downstream equipment or facilitating mud treatment.
[0010] Preferably, a fall-prevention frame is fixedly connected to the upper surface of the connecting pipe at the position corresponding to the filter flange, and the cross-sectional dimensions of the fall-prevention frame are adapted to the cross-sectional dimensions of the filter flange.
[0011] The above components achieve the following effect: the anti-fall frame is fixedly connected to the upper end of the connecting pipe and tightly fitted to the outside of the filter flange, which helps to prevent the risk of foreign objects falling into the well.
[0012] Preferably, the fixing component includes a connecting frame and a nut. One side of the connecting frame is fixedly connected to the arc surface of the mud docking frame. A rotating rod is rotatably connected to the inner wall of the connecting frame. A connecting rod is fixedly connected to the surface of the rotating rod by means of the nut. The cross-section of the connecting rod is U-shaped. An inlay block is fixedly connected to the surface of the mud fixing frame at the position corresponding to the connecting rod. The cross-section of the inlay block is barbed. The cross-sectional dimensions of the connecting rod are adapted to the cross-sectional dimensions of the inlay block.
[0013] The aforementioned components achieve the following effects: the fixing assembly provides an efficient, robust, and relatively easy-to-operate connection method. The position of the connecting rod can be adjusted by rotating the rod and nut. The "U"-shaped cross-section of the connecting rod matches the hook-shaped cross-section of the insert block, forming a reliable mechanical lock, ensuring the tightness and stability of the connection between the mud collection assembly and the frame of the sewage collection assembly.
[0014] Preferably, the arc surfaces of the mud fixing frame and the mud docking frame are rotatably connected with a plurality of fixing rings, and the fixing rings are stainless steel rings.
[0015] The aforementioned components achieve the following effect: multiple rotatable fixing rings are set on the arc surface of the mud fixing frame and the mud docking frame, while stainless steel material is used to ensure strength and corrosion resistance, providing reliable fixing points for collecting umbrella fabric.
[0016] Preferably, the collection device further includes a support frame, the inner wall of which is fixedly connected to the upper arc surface of the connecting pipe, and the upper surface of the support frame abuts against the lower surfaces of the mud docking frame and the mud fixing frame.
[0017] The effect achieved by the above components is that the support frame is fixed on the upper arc surface of the connecting pipe, and its key function is to provide a stable support platform for the mud fixing frame and mud docking frame in the mud collection assembly above.
[0018] Preferably, the inner wall surfaces of the sewage fixing frame and the sewage docking frame are both fixedly connected with through pipes, and the lower surfaces of the sewage fixing frame and the sewage docking frame are both fixedly connected with several base plates, the base plates being reinforced steel plates.
[0019] The aforementioned components achieve the following effects: Through-pipes are installed on the wastewater fixing frame and wastewater connection frame, providing an outlet for the collected wastewater to be discharged or diverted, facilitating the flow of wastewater to treatment equipment or storage containers. Several reinforcing steel base plates fixedly connected to the lower surface significantly enhance the structural strength and rigidity of the wastewater collection assembly's bottom, enabling it to withstand the weight of the collected wastewater, external loads, and potential impacts, preventing bottom deformation and damage, and ensuring the stability and service life of the wastewater collection assembly.
[0020] Compared with related technologies, the mud and wastewater collector provided by this utility model has the following beneficial effects:
[0021] Adding mud collection equipment to the drill pipe face platform enables efficient mud recovery. This collection device effectively separates and directionally collects mud and wastewater. Mud and wastewater generated during drill pipe operation pass through the connecting pipe. A mud collection component at the upper end of the connecting pipe primarily collects the heavier mud, while a wastewater collection component at the lower end collects the lighter wastewater, achieving initial separation. A filter component on the upper inner wall further filters the fluid entering the mud collection component or blocks large particles. Additionally, a collection umbrella covering the connecting pipe at the locations of the mud and wastewater collection components effectively prevents splashing or leakage of mud and wastewater during collection, ensuring concentrated collection and environmental cleanliness.

[0032] The working principle of the mud and wastewater collector provided by this utility model is as follows: During the drilling process, the high-speed ejected mud mixture is first blocked and isolated by the protective collection structure composed of the mud collection component 41 and the collection umbrella cloth 44, preventing it from splashing to the outside of the drilling platform and polluting the working environment. Under its own gravity and the guiding effect of the collection umbrella cloth 44, the blocked mud flows downward and is directly introduced into the mud collection component 41 located at the upper end of the connecting pipe 1. The collected mud mixture enters the upper inlet of the connecting pipe 1 through the mud collection component 41. During the inflow process, it will pass through the filter component 43. The connecting hole 432 on the filter flange 431 acts as a screen, allowing liquid mud to pass through while intercepting larger solid particles, realizing the preliminary filtration and purification of the mud. After filtration, the mud re-enters the interior of the connecting pipe 1 and can be pumped back to continue participating in the drilling cycle, thereby directly realizing the recycling of mud and greatly saving the cost of purchasing new mud materials.
[0033] During this process, a large splash area, exceeding the protective collection structure formed by the mud collection component 41 and the collection umbrella 44, mainly consists of sewage and a small amount of fine particles, which will scatter onto the drilling platform surface. The platform surface has drainage holes, through which the sewage flows out of the platform. The outflowing sewage is caught by the collection umbrella 44, located below the platform and surrounding the equipment. The collection umbrella 44 forms an inclined guide surface, concentrating the scattered sewage together. All the sewage is guided by the collection umbrella 44 and flows into the sewage collection component 42 located at the bottom of the equipment. The through pipe 423 at the bottom of the sewage collection component 42 connects to an external pipeline, ultimately guiding the collected sewage to a designated treatment facility or storage location for centralized treatment, avoiding environmental pollution caused by the indiscriminate flow of sewage. Through the coordinated work of the mud collection component 41, the sewage collection component 42, and the collection umbrella 44, this device successfully separates drilling waste into two paths: "recyclable mud" and "sewage requiring treatment," thereby achieving environmentally friendly collection of the entire system, saving drilling costs and protecting the environment.
