Description

Technical Field

[0001] This invention relates to a sea sand desalination device, belonging to the field of sea sand purification technology. Background Technology

[0002] With natural sand resources becoming increasingly scarce, river sand has become insufficient to meet the demand for construction materials in recent years, making the effective utilization of other sand sources an inevitable trend.

[0003] For various reasons, coastal areas are using sea sand purification to alleviate the supply-demand imbalance of river sand resources. my country has extremely abundant shallow sea sand resources, suitable for large-scale industrial mining, and characterized by good sorting and concentrated distribution. From an economic perspective, sea freight is relatively inexpensive, reducing production costs. Therefore, effectively utilizing abundant sea sand resources can solve the widespread shortage of river sand resources in coastal areas and avoid long-distance mining and replenishment of sand and gravel, thus playing a significant role in energy conservation and environmental protection. However, although sea sand is clean, its high salinity significantly impacts engineering quality. River sand is currently scarce and expensive, while sea sand is relatively much cheaper. Washing and drying sea sand with fresh water to meet the requirements for use as a building material has become a new technical challenge. In recent years, due to the depletion of river sand resources, some coastal cities have used sea sand to mix concrete and mortar in construction projects, leading to chloride ion corrosion, reducing the durability of the projects, and posing potential quality risks.

[0004] For example, Chinese utility model patent CN215430071U discloses a sea sand desalination line in the field of sea sand treatment technology. The line includes a conveyor feeder, with a drum sand screener connected to its inner end. The drum sand screener is connected to its inner end, and a dechlorination desalination machine is connected to its inner end. The lower end of the dechlorination desalination machine is connected to a wastewater purification tank. When sand enters the left end of the inner cavity of the screening drum, the washed fine sand is transported to the dechlorination desalination machine for dechlorination treatment. The treated fine sand is then transported to the dewatering dewatering machine for dewatering treatment. Finally, the treated fine sand is discharged via a winch unloader, which facilitates the promotion of this utility model.

[0005] Although the aforementioned sea sand desalination line provides a sea sand desalination process that can treat and purify sea sand relatively well, the process is still relatively simple and the treatment is not thorough enough, resulting in a long purification cycle and serious waste of water resources.
