[0030] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0031] like Figures 1 to 3 As shown, the utility model discloses an aquaculture circulating water treatment device, comprising an inlet tank 1, a filter tank 2, a biochemical tank 3 and an overflow tank 4 which are arranged in sequence. The aquaculture circulating water enters the inlet tank 1, passes through the filter tank 2, the biochemical tank 3 and the overflow tank 4 in sequence, and is then output and can be recycled.

[0032] A water inlet is provided at the bottom of the side wall of the water inlet tank 1 close to the filter tank 2 , so that water enters from the bottom of the filter tank 2 .

[0033] The bottom surface of the filter pool 2 is an inclined surface, and the side of the bottom surface of the filter pool 2 close to the water inlet tank 1 is the lower end.

[0034] A filter mechanism 5 is provided in the filter pool 2, and the filter mechanism 5 intercepts and filters impurities in the water. The filter mechanism 5 includes a filter shell 51, which is in the shape of a rectangular parallelepiped and has a mesh structure, and is filled with filter material 52. A plurality of hanging rings 53 are provided on the top of the filter shell 51, and a movable connection component 6 is provided between the bottom of the filter shell 51 and the bottom of the filter pool 2. After the filter material 52 intercepts a large number of impurities, when replacement and maintenance are required due to the accumulation of dirt, the filter shell 51 is lifted out of the filter pool 2 through the hanging ring 53, and after replacing the filter material 52 in the filter shell 51, the filter shell 51 is lifted into the filter pool 2 through the hanging ring 53, and the filter shell 51 is fixed through the movable connection component 6.

[0035] The movable connection assembly 6 includes a plurality of lower support columns 61 arranged on the bottom surface of the filter tank 2, and the tops of the plurality of lower support columns 61 are in the same horizontal plane. A slot 63 is provided inwardly at the top of the lower support column 61, and the slot 63 is cylindrical and coaxial with the lower support column 61. A truncated cone-shaped guide cover 64 is coaxially provided at the top of the lower support column 61, and the smaller diameter end of the guide cover 64 is connected to the lower support column 61.

[0036] The movable connection component 6 also includes a plurality of upper support columns 62 arranged at the bottom of the filter shell 51, and the positions of the plurality of upper support columns 62 correspond to the plurality of lower support columns 61 respectively. A truncated cone-shaped guide block 65 cooperating with the guide cover 64 is coaxially provided at the bottom end of the upper support column 62. The larger diameter end of the guide block 65 is connected to the upper support column 62. A plug column 66 cooperating with the slot 63 is coaxially connected to the bottom end of the guide block 65. The bottom end of the plug column 66 and the inner end of the slot 63 are respectively provided with strong magnets 67 cooperating with each other, and the surface of the strong magnet 67 is covered with a layer of waterproof film.

[0037] When the filter shell 51 is fixed in the filter pool 2, the plurality of upper support columns 62 are roughly aligned with the lower support columns 61. During the descent of the filter shell 51, the plug column 66 first enters the guide cover 64. The guide of the guide cover 64 causes the plug column 66 to finally slide into the slot 63 to achieve alignment between the upper support column 62 and the lower support column 61. The guide block 65 also finally slides into the guide cover 64. The plug column 66 and the strong magnet 67 of the slot 63 strongly attract each other to fix the filter shell 51. When the filter shell 51 is hoisted out, the filter shell 51 is pulled by the lifting ring 53 until the plug column 66 is separated from the strong magnet 67 of the slot 63 to achieve separation of the upper support column 62 from the lower support column 61.

The plurality of oxygenation pipes 8 are arranged in parallel and at equal intervals in the same plane. A plurality of air holes are evenly arranged on the top of the oxygenation pipes 8, and air bubble stones are arranged in the air holes. The sides of the plurality of oxygenation pipes 8 are provided with oxygen delivery pipes 9 connected to the oxygen delivery pipes 9, and the oxygen delivery pipes 9 are connected to an external oxygen source.

[0041] A water outlet is provided at the top of the side wall of the biochemical pool 3 near the overflow trough 4, and an interception net 10 is provided in the water outlet. The water in the biochemical pool 3 flows into the overflow trough 4 after passing through the interception net 10 in the form of overflow, and impurities in the water are retained on the interception net 10.

[0042] The water inlet trough 1 of the utility model receives water flow from the breeding pond, and the water flow passes through the filter tank 2 and the biochemical tank 3 in sequence and then flows back to the breeding pond through the overflow trough 4. The filter tank 2 filters and intercepts impurities in the water body. The biochemical tank 3 has an oxygen-enhancing air flow and MBBR fillers, which realize water purification by increasing the dissolved oxygen in the water body and the bacterial attachment area. The filter mechanism 5 is easy to load and unload in the filter tank 2 through the movable connection component 6, so that the maintenance operation efficiency of the filter mechanism 5 is improved, so as to timely maintain the filtering performance of the filter mechanism 5.
