Description

Technical Field

[0001] This utility model relates to the field of recirculating aquaculture technology, specifically a recirculating water filtration device for sturgeon farming. Background Technology

[0002] In sturgeon farming, water quality management is one of the key factors in ensuring the healthy growth of sturgeon. Recirculating aquaculture systems (RAS) remove suspended solids, organic matter, ammonia nitrogen, and other harmful substances from the water through filtration devices, maintaining stable water quality. However, existing RAS filtration devices often suffer from low filtration efficiency, failing to achieve rapid and multi-stage filtration of the circulating water. This limits the improvement of farming efficiency and the expansion of farming scale. In addition, some filtration devices are prone to clogging during the filtration process, requiring frequent cleaning and maintenance, increasing farming costs and labor intensity.

[0003] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a recirculating water filtration device for sturgeon farming. Utility Model Content

[0007] As a preferred technical solution, the filter assembly includes a top cover installed at the top of the filter cylinder, a flow port is provided through the top cover, a circulation pipe is installed in the flow port, a primary mesh cylinder is provided at the bottom of the flow port, a secondary mesh cylinder is provided outside the primary mesh cylinder, and a tertiary mesh cylinder is provided outside the secondary mesh cylinder.

[0008] As a preferred technical solution, the inner diameter of the first-level mesh is greater than that of the second-level mesh, which is greater than that of the third-level mesh.

[0018] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0019] like Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a technical solution for a sturgeon aquaculture recirculating water filtration device: it includes a base 1, on which a filter cylinder 2 is mounted. A circulation assembly is connected to the filter cylinder 2, which includes a circulation pump 21. The input end of the circulation pump 21 is connected to a circulating water inlet pipe 22, and a control valve 23 is installed on the circulating water inlet pipe 22. The output end of the circulation pump 21 is connected to a circulating water outlet pipe 24, and a main circulation pipe 25 is connected to the outlet pipe 24. The tail end of the main circulation pipe 25 is connected to the filter cylinder 2.

[0020] like Figure 2 As shown, a filter assembly is installed inside the filter cartridge 2. The filter assembly includes a top cover 31 installed at the top of the filter cartridge 2, with a flow port 32 extending through the top cover 31. A circulation pipe 26 is installed inside the flow port 32. A primary screen cylinder 33 is installed at the bottom of the flow port 32, a secondary screen cylinder 34 is installed outside the primary screen cylinder 33, and a tertiary screen cylinder 35 is installed outside the secondary screen cylinder 34. The inner diameter of the mesh of the primary screen cylinder 33 is larger than that of the secondary screen cylinder 34, and the inner diameter of the mesh of the secondary screen cylinder 34 is larger than that of the tertiary screen cylinder 35, so as to achieve graded filtration of suspended solids of different sizes.

[0021] like Figure 3 As shown, a drain port is provided at the bottom of the filter cartridge 2, which is connected to the outside via a drain pipe to facilitate regular cleaning of sediment inside the filter cartridge 2. A clean water pipe 27 is provided on the outer wall of the filter cartridge 2, which can be easily rinsed, further improving the service life of the filtration device.

[0022] In practical applications, water in the recirculating aquaculture system enters the filter cartridge 2 through the recirculating water inlet pipe 22. After undergoing multi-stage filtration by the filtration components, the water is pumped into the aquaculture pond by the recirculating pump 21 through the recirculating main pipe 25 and the recirculating water outlet pipe 24. Deposits inside the filter cartridge 2 can be cleaned by opening the drain outlet, while the clean water pipe 27 on the outer wall of the filter cartridge 2 can be used to rinse the filter cartridge 2 to maintain its cleanliness and filtration efficiency.

[0023] This utility model's filtration device, through the multi-stage mesh cylinder design, achieves rapid and multi-stage filtration of circulating water, effectively improving filtration efficiency, ensuring water cleanliness, and providing a healthier living environment for sturgeon. Simultaneously, the drain outlet design at the bottom of the filter cylinder and the water purification pipe on the outer wall of the filter cylinder make cleaning and maintenance simple and quick, greatly reducing the frequency and labor intensity of maintenance, lowering aquaculture costs, and making it possible to expand the scale of aquaculture.
