Abstract
Description
Technical Field
[0001] This utility model relates to the field of aquaculture technology, specifically to a water purification device for aquaculture. Background Technology
[0002] Aquaculture water often contains a large amount of suspended solids, such as feed residue, feces, and algae. Water purification equipment can effectively remove these suspended solids through physical filtration, sedimentation, or flotation, keeping the water clear and transparent. By using water purification equipment, the cleanliness and stability of the water can be maintained, thereby increasing the stocking density and yield.
[0003] Patent document CN111804034A discloses a water purification device for aquaculture. It uses a sealed snap-fit structure to connect the lower and middle shells, facilitating the disassembly and assembly of the water tank. The filtration structure filters water layer by layer, and the horizontal pipe and outlet holes guide and disperse the water flow, enhancing the filtration effect. A washing column prevents sludge accumulation above the filtration structure, and the position of the washing column corresponds to the recessed areas, ensuring thorough cleaning of the recesses most prone to sludge buildup. The driving wheel rotates continuously under the drive of a power source, which in turn drives the driven wheel to reciprocate, creating turbulence within the water tank for better agitation. A lifting mechanism can raise the upper shell, allowing the middle shell and filter box to be removed together for maintenance, cleaning, or filtration structure repair. However, this patent has the following problems in practical use:
[0004] This water purification equipment cleans the surface of the filter structure using a scrubbing column to prevent the accumulation of sludge. However, because the scrubbing column is difficult to remove blockages from the filter structure during use, the water purification efficiency can still be affected when there are many blockages, resulting in poor practicality of this aquaculture water purification equipment.
[0005] Therefore, a water purification device for aquaculture is proposed to solve the problems mentioned above. Utility Model Content
