[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] The Drilling Slurry Solid-Liquid Separation and Storage Unit is a device specifically designed to process waste drilling fluid generated during the drilling process. Its primary function is to separate solid particles from liquids in the drilling fluid for subsequent processing and storage, reducing environmental pollution and improving resource recovery. Function: Environmental Protection: By separating solid particles from liquids, environmental pollution is reduced, particularly preventing the damage to soil and water bodies caused by harmful components such as heavy metals, polymers, and oils. Resource Recovery: The separated liquid can be discharged in a manner that meets standards, while the solid portion can be landfilled or solidified for resource recovery. Improved Efficiency: Solid-liquid separation improves drilling fluid recovery efficiency, reduces drilling fluid waste, and lowers costs. Potential Problems During Use: Filter Clogging: During the filtration process, the filter pores can easily become clogged by solid particles in the drilling fluid, resulting in reduced filtration efficiency and decreased device performance. Equipment Wear: Because drilling fluid often contains abrasive particles, long-term use can cause wear on the solid-liquid separation equipment, requiring regular maintenance and component replacement. Operational complexity: Some solid-liquid separation equipment is complex to operate and requires professional operators to operate, which increases the operating cost and difficulty. Use of chemicals: In the solid-liquid separation process, chemical agents such as flocculants and coagulants may need to be used, which may bring additional environmental risks and costs. Energy consumption issues: Certain solid-liquid separation technologies such as centrifugal separation may require higher energy consumption, increasing the energy cost of the drilling process. In summary, the slurry solid-liquid separation storage device in the drilling process plays an important role in environmental protection and resource recovery, but during use, it is also necessary to pay attention to solving problems such as filter blockage, equipment wear, and operational complexity to ensure efficient and stable operation of the equipment. The background technology of the slurry solid-liquid separation storage device in the drilling process mainly includes the following aspects: Environmental protection and resource recovery: The waste drilling fluid generated during the drilling process contains a variety of harmful substances, such as heavy metals, polymers, oils, etc., which cause serious pollution to the environment. The application of solid-liquid separation technology can effectively reduce the impact of these pollutants on the environment, realize the harmless treatment of waste and the recycling of resources. Drilling quality assurance: During the drilling process, the solid-liquid separation device can process and monitor the mud performance to ensure the quality of drilling. By effectively separating the waste solid and liquid, it can be harmlessly treated on site before being discharged or transported to a designated location for preliminary treatment. Technology maturity: Although the vast majority of mud materials sold on the market are marked with green and environmentally friendly characteristics, there is a lack of reports or certificates recognized by authoritative organizations and standards. At the level of universities and research institutes, the technology for harmless treatment of waste solid and liquid is relatively mature, but its market utilization rate is not high, and it should be refined in terms of configuration for different drilling equipment. Solid-liquid separation process: Solid-liquid separation technology is a pretreatment before solidification. The process flow is simple, and the main contents include destabilization and flocculation.Chemical destabilization is achieved by destabilizing the waste material by breaking its stable state. A coagulant (a mixture of flocculants and coagulants) is then added to modify the physical and chemical properties of the drilling fluid system, disrupting its colloidal structure and achieving solid-liquid separation. Solid-liquid separation equipment: Solid-liquid separation equipment has rapidly developed in terms of structure, separation efficiency, automation level, functional integration, product quality, and reliability, narrowing the performance gap with products from developed European countries. Solid-liquid separation equipment is widely used in industries such as starch, chemicals, pharmaceuticals, and industrial wastewater treatment. The main reasons for using solid-liquid separation and storage equipment for drilling slurry include: Reducing environmental pollution: Solid-liquid separation technology can reduce environmental pollution caused by waste drilling fluid and protect soil and water from harmful substances. Improving resource utilization: The separated liquid can be discharged in a standard manner, while the solid portion can be landfilled or solidified for resource recovery. Improving drilling efficiency: Solid-liquid separation can improve drilling fluid recovery efficiency, reduce drilling fluid waste, and lower costs. Responding to the demand for green exploration: With the increasing requirements for environmental protection, green exploration has become an important part of the new round of strategic actions for mineral exploration breakthroughs. The application of solid-liquid separation technology is one of the key technologies to achieve green exploration.
