Description

Technical Field

[0001] The utility model belongs to the field of coal mine wastewater filtration and relates to a crawler-type slag-water membrane separator for mining. Background Art

[0002] In coal mining operations, ensuring the efficient recycling of underground construction water and the effective treatment of slag water is a key link in maintaining production efficiency and environmental protection. At present, a large amount of water is generated in underground coal mine construction, and the accompanying slag water treatment has become a major challenge. Traditional treatment methods mostly rely on a process combining multi-stage sedimentation and chemical flocculation, aiming to remove suspended particles in the water through physical and chemical effects. However, this method has obvious limitations: the effluent water quality fluctuates greatly, the dependence on flocculants leads to a large consumption of reagents, and it occupies a large space and has high operating costs. In view of these drawbacks, some mines adopt a simplified natural sedimentation strategy, which only achieves basic solid-liquid separation of drill cuttings, and then uses sewage discharge facilities to collect them in the sewage storage area, and further pump them to the surface for deep purification. This process is not only costly, but also significantly increases the overall operation and maintenance burden of coal mines.

[0003] In recent years, although the application of inorganic ceramic membrane technology in the field of domestic water treatment has become increasingly mature and widely used in the treatment of drinking water and various industrial wastewater, its application exploration in the underground environment of coal mines has been relatively lagging behind. The unique tunnel environment of coal mines is complex and changeable, which places higher requirements on the stability and safety of equipment, limiting the direct transplantation of ceramic membrane technology. Existing attempts are mostly centered around building an integrated system that includes multi-stage sedimentation, flocculation, and ceramic membrane circulation filtration. This not only requires the pre-construction of large pretreatment tanks, but also because of the cumbersome process, it is mainly suitable for large-scale centralized treatment scenarios. Furthermore, the electrical and mechanical components of such systems must undergo strict explosion-proof certification before they can be put into underground use, which increases the difficulty of implementation.

[0004] In response to the above problems, pneumatically controlled ceramic membrane filtration solutions have appeared on the market, integrating key components such as jig screens, raw water pools and ceramic membrane filtration units, aiming to improve purification efficiency. However, this type of system also has its limitations, mainly reflected in the need to dig sedimentation tanks in the tunnels, lack of flexibility, and being completely fixed in a certain position. In addition, a stable supply of compressed gas is required to maintain system operation, which further limits its adaptability and convenience in the complex and changeable underground coal mine environment. Therefore, it is particularly urgent to develop a more efficient, flexible and economical coal mine slag water treatment technology. Utility Model Content
