Description

Technical Field

[0001] This utility model belongs to the field of mining drilling and geological exploration technology, specifically relating to a mobile processing device that can be quickly deployed and integrates mud dewatering and clean water recovery functions, suitable for drilling mud reduction treatment in scenarios such as metal mines, coal mines, and tunnel engineering. Background Technology

[0002] As is well known, mining and tunnel construction generate large amounts of muddy wastewater, which in turn produces a significant amount of waste drilling mud. Waste drilling mud has a complex composition, containing pollutants such as clay, drill cuttings, chemical treatment agents, and oily waste. On the one hand, excessively high levels of low-quality solids, especially fine sand and silt, can lead to increased mud density, deteriorated rheological properties (increased viscosity and shear stress), increased filtration loss, and decreased lubricity, resulting in a series of problems such as reduced drilling speed, increased risk of stuck drill bits, accelerated drill bit wear, and reservoir damage. On the other hand, traditional treatment methods rely on excavating mud pits for on-site solidification, which has drawbacks such as high environmental pollution risks, large land occupation, and low resource utilization, and can also pollute the surrounding soil, vegetation, and ecological environment. Therefore, efficiently removing harmful solids from drilling mud is a crucial step in ensuring the smooth progress of drilling operations, and scientifically and correctly treating drilling mud to prevent adverse impacts on the ecological environment is an urgent problem to be solved.

[0003] Traditional mud treatment systems mostly employ fixed or decentralized equipment, which suffers from inherent drawbacks such as large footprint, long installation and dismantling times, low relocation efficiency, complex piping connections between equipment, difficulty in adapting to frequent drilling operations, and high costs associated with repeated construction. While existing mobile treatment equipment offers mobility, its functionality is limited, lacking a complete integrated process from pretreatment to solid-liquid separation, and it fails to address the issue of filtrate recycling. Therefore, there is an urgent need to develop a mobile integrated mud treatment device to effectively solve these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a mobile drilling mud integrated treatment device that integrates high efficiency in solid phase removal, rapid deployment and transportation, and intelligent convenience, so as to solve the problems of high relocation cost and low treatment efficiency of traditional fixed treatment stations. It is suitable for rapid deployment in open-pit mines, tunnel construction and other scenarios.

[0048] Example 1

[0049] The mobile base plate 29 adopts a steel frame structure with hydraulic support legs 30 at the bottom, allowing the entire unit to be transported on a heavy-duty truck 32. The screen filter head 2 is made of 304 stainless steel with a 10mm aperture. The vibrating screen 4 is installed at an angle, with a screen aperture of 1mm optional. The screened slag is discharged to the slag box 5 via a screw conveyor. The flocculation tank 14 has a dosing port at the top, where polyacrylamide (PAM) flocculant is precisely added via a metering pump. The filter press 21 adopts a chamber structure, with its filter plates made of reinforced polypropylene, and a working pressure range of 0.8-1.5MPa. The outlet of the filter press 21 is connected to the cake conveyor belt 23, and the filtrate, after sedimentation treatment, enters the filtrate collection tank 25 for reuse. The electrical control cabinet 27 has a built-in touch screen, supporting manual / automatic mode switching, and can be set with a cycle program of "filter tank full → automatic start of pressing → slag unloading and reset"; the flocculant dosing pump adjusts the PAM dosage in real time according to the slurry flow rate; the electrical control cabinet 27 displays parameters such as pressure and flow rate in real time.

[0050] When the mobile drilling mud integrated treatment unit is working, the mud from the mud tank 1 undergoes primary screening through the screen filter head 2 to remove large particles of stone, completing the pretreatment of the mud. The first mud pump 3 is activated via the electrical control cabinet 27, and the mud enters the vibrating screen 4 through a pipeline for secondary screening. The upper screen has a mesh size of 10-20, and the lower screen has a mesh size of 60-100. After secondary screening, the large particles separated by the vibrating screen 4 are discharged to the slag bin 5 via a screw conveyor for solid slag collection. Then, the electrical control cabinet 27 controls the opening of the second electric valve 8, the third electric valve 10, and the second mud pump 9, allowing the secondary-screened mud to enter the mixing tank 6. Lime slurry is added through the chemical addition port I11 of the mixing tank 6 to adjust the pH value of the mud to 7-8, thereby optimizing the mud dewatering performance. If dilution is required, the electrical control cabinet 27 controls the opening of the first electric valve 7, adding clean water from the clean water tank 28 to the mixing tank 6. After stirring, a uniform mud is output. The electrical control cabinet 27 controls the activation of the third mud pump 13, which transports the prepared mud to the flocculation tank 14 for flocculation. Polyacrylamide (PAM) is added to the flocculation tank 14 via a dosing pump to form flocs. The flocculated mud is then output via the fourth mud pump 17 and stored in the mud storage tank 18. Finally, the electrical control cabinet 27 controls the activation of the fifth mud pump 20, which transports the mud from the storage tank 18 to the filter press 21 for dewatering. After dewatering, the conveyor belt motor 24 activates, and the mud is transported by the conveyor belt 23 and discharged through the discharge port 26 with a moisture content of approximately 19%. After discharge, the filter plates 22 or pressing mechanism of the filter press 21 automatically reset. The filtrate produced by dewatering enters the filtrate collection tank 25. After sedimentation and stratification, the upper layer of clear water (SS≤50mg / L) is sent to the clear water tank 28 for clean water recovery, used for equipment cleaning or production reuse; the lower layer of high-turbidity filtrate is returned to the mixing tank 6 for further treatment. The electrical control cabinet 27 automatically adjusts parameters such as dosage and pressure, and triggers an audible and visual alarm in case of a malfunction. Flow meters are installed in the internal piping to detect mud flow.
