Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of seawater filtration, and particularly relates to a seawater sand filter tank. Background Art
[0002] A seawater sand filter tank is a device used for seawater filtration and purification, and is commonly found in fields such as seawater aquaculture, seawater aquariums, and seawater desalination. Its internal structure usually includes the following main components: Filter medium: The core component of the sand filter tank is the filter medium, usually a layer of sand or other media with a specific particle size and type, such as silica sand, glass sand, etc. These filter media can effectively filter suspended solids, organic matter, and impurities in seawater, making the seawater clear and clean. Filter tank housing: The filter tank housing is a container that houses the filter medium, usually made of corrosion-resistant materials such as fiberglass-reinforced plastic or stainless steel. The design of the filter tank housing requires good sealing and pressure resistance to ensure that seawater can effectively pass through the filter medium for filtration; Inlet and outlet: The filter tank is usually provided with an inlet and an outlet for introducing seawater into the filter tank and discharging the filtered clear water. These ports are usually located at the top or side of the filter tank and are equipped with valves or pipes connected to a water pump or pipeline system; Waste discharge system: In order to remove the dirt and impurities accumulated in the filter medium, the filter tank is usually equipped with a waste discharge system. This can be a drain valve or a drain pipe. By opening the waste discharge system, the filter medium can be cleaned and rinsed regularly to maintain its filtering effect; Support structure: In order to support the filter medium and ensure its stability, a support structure such as a partition, bracket, or fence is usually provided inside the filter tank. These structures can help fix the filter medium, prevent it from collapsing or moving, and also help optimize the flow path and distribution of seawater in the filter medium. These components together constitute the internal structure of the seawater sand filter tank, ensuring that it can effectively filter and purify seawater to meet the needs of different application scenarios.
[0003] In the prior art, the filter elements of some filters cannot be replaced individually. When the sundries filtered inside the filter element accumulate to a certain extent, the filtering effect will be affected.
