Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a recirculating aquatic live animal display tank. Background Technology

[0002] Many seafood markets, hotels, and restaurants now use live aquatic animal display tanks to attract customers. However, traditional live aquatic animal display tanks often cause problems due to difficulties in water quality management: stagnant water easily accumulates aquatic animal feces and uneaten food, leading to water quality deterioration and algae growth. Frequent water changes can also harm aquatic animals due to sudden changes in water temperature or quality. Therefore, a circulating live aquatic animal display tank is needed to reduce the frequency of full water changes (e.g., only partial water changes are needed monthly), maintain stable water quality, reduce maintenance difficulty, and allow the tank to more closely resemble a natural ecological balance, thereby improving the survival rate of aquatic animals and plants. Utility Model Content

[0003] This invention provides a circulating aquatic live display tank that can maintain stable water quality and improve the survival rate of aquatic animals and plants.

[0004] To solve the above-mentioned technical problems, this utility model provides a circulating aquatic live animal display tank, characterized in that it includes:

[0005] Aquatic animal breeding tanks;

[0006] An ecological purification tank includes a plant cultivation tank and a filter tank. A filter partition is provided between the plant cultivation tank and the filter tank. A plant cultivation wall is provided inside the plant cultivation tank. A filter device is provided inside the filter tank. The filter device is provided with a physical filter layer and a biological filter layer. The lower part of the filter tank is connected to the bottom of the aquatic animal breeding tank.

[0007] A water circulation device, comprising a water pump and an outlet pipe, wherein the water pump is located at the bottom of the aquatic animal breeding tank, one end of the outlet pipe is connected to the water pump, and the other end of the outlet pipe is connected to the green plant breeding tank.

[0008] As a preferred embodiment of the above technical solution, both the green plant cultivation wall and the filter partition are positioned above the filter device.

[0009] As a preferred embodiment of the above technical solution, the green plant cultivation wall includes a mesh support and a green plant ecological cloth, the green plant ecological cloth covering the surface of the mesh support, and the mesh support being used to fix the green plants.

[0010] As a preferred embodiment of the above technical solution, the green plant cultivation wall includes a porous planting trough, which is filled with a lightweight planting substrate.

[0011] As a preferred embodiment of the above technical solution, the physical filtration layer is provided with filter cotton, a first filter screen, biochemical cotton and a second filter screen in sequence, the physical filtration layer is located above the biological filtration layer, and the biological filtration layer is located above the water outlet pipe.

[0012] As a preferred embodiment of the above technical solution, the biofiltration layer is provided with a bio-attachment substrate, which is a porous ceramic.

[0013] As a preferred embodiment of the above technical solution, the filter device is provided with an overflow plate, which is located directly above the filter cotton.

[0014] As a preferred embodiment of the above technical solution, the bio-cotton is used to filter impurities and cultivate nitrifying bacteria, and the bio-attached substrate is used to filter impurities and cultivate nitrifying bacteria.

[0015] As a preferred embodiment of the above technical solution, the filter baffle is made of volcanic rock and has a number of filter pores.

[0016] As a preferred embodiment of the above technical solution, the circulating aquatic live display tank is further provided with a lighting module, which includes LED lights and a control switch. The light emitted by the LED lights illuminates the green plant cultivation wall, and the control switch is electrically connected to the LED lights.

[0017] This utility model provides a circulating aquatic live animal display tank, comprising: an aquatic animal breeding tank and an ecological purification tank. The aquatic animal breeding tank is used to raise various aquatic animals. The ecological purification tank is equipped with a green plant cultivation wall, a filter baffle, and a filtration device. The green plant cultivation wall is used to cultivate aerial root plants such as pothos and spider plants. The plant roots naturally hang down into the water, directly absorbing harmful substances such as ammonia nitrogen and nitrates in the water and inhibiting excessive algae growth. The biological filtration layer degrades residual organic matter through microorganisms. In use, the water pump is activated to draw water from the aquatic animal breeding tank and flow into the green plant breeding tank through the outlet pipe. After being purified by the green plant roots, the water passes through the filter baffle to initially filter large particles of impurities before flowing to the filtration device. It then passes through the physical filtration layer to intercept suspended solids and the biological filtration layer to decompose organic matter. Finally, the purified water flows back into the aquatic animal breeding tank through the return pipe, forming a closed loop. By driving water flow sequentially through the plant root zone and multi-stage filtration layers, the system achieves the gradual decomposition of aquatic animal feces and uneaten feed, as well as the transformation of harmful substances, significantly improving water stability while reducing the frequency of manual water changes and lowering water consumption. Through plant absorption of ammonia nitrogen and nitrates, aquatic animal metabolism providing carbon dioxide, and microbial decomposition of organic matter, a closed-loop material cycle is formed. Combined with the circulating water flow, this maintains long-term stability of the water's pH and dissolved oxygen levels. Furthermore, the green plant wall and the filtration device can be independently disassembled for cleaning or component replacement, greatly reducing maintenance intensity. Combined with regular partial water changes, such as replacing 1 / 3 of the water monthly, this maintains ecological balance and avoids the environmental impact on aquatic animals caused by frequent full-tank water changes in traditional aquaculture tanks.

[0028] This utility model embodiment provides a circulating aquatic live animal display tank, including: an aquatic animal breeding tank 1 and an ecological purification tank 2. The aquatic animal breeding tank 1 is used to raise various aquatic animals. The ecological purification tank 2 is equipped with a green plant cultivation wall 301, a filter partition 201, and a filter device 401. The green plant cultivation wall 301 is used to cultivate aerial root plants such as pothos and spider plants.

The biological filter layer 401... 03. Microbial degradation of residual harmful substances: During use, the water pump 501 is activated to draw water from the aquatic animal rearing tank 1, which flows into the green plant rearing tank 3 through the outlet pipe 502. After being purified by the roots of the green plants, the water passes through the filter baffle 201 for preliminary filtration of large particles before flowing to the filter device 401. It then passes through the physical filter layer 402 to intercept suspended solids and the biological filter layer 403 to decompose organic matter. Finally, the purified water flows back into the aquatic animal rearing tank 1 through the return pipe, forming a closed loop. By driving the water flow through the plant root zone and multiple filtration layers, the aquatic animal feces and uneaten feed are decomposed and harmful substances are transformed step by step, significantly improving water stability while reducing the frequency of manual water changes and lowering water consumption. Through plant absorption of ammonia nitrogen and nitrates, aquatic animal metabolism providing carbon dioxide, and microbial decomposition of organic matter, a closed-loop material cycle is formed. Combined with the circulating water flow, this maintains the long-term stability of the water's pH and dissolved oxygen levels. In addition, the green plant cultivation wall 301 and the filter device 401 can be disassembled, cleaned or have their parts replaced independently, which greatly reduces the maintenance intensity. Combined with regular partial water changes, such as changing 1 / 3 of the water volume every month, it can maintain the ecological balance and avoid the environmental impact on aquatic animals caused by frequent whole-tank water changes in traditional aquatic animal breeding tanks 1.
