[0002] Aquaculture is a production activity involving the breeding, cultivation, and harvesting of aquatic plants and animals under human control. Aquaculture tanks are used in aquaculture. During the cultivation of aquatic plants and animals, fish excrement and leftover feed accumulate in the water, which leads to water quality deterioration and affects the survival of fish. Therefore, it is necessary to change the water in the tank.

[0003] In aquaculture, fish tanks are commonly used to raise fish. However, during the rearing process, fish excrement and leftover feed accumulate in the water, leading to water quality deterioration and affecting the survival of the fish. There is room for improvement in this regard. Utility Model Content

[0016] Beneficial effects

[0017] This utility model provides an aquaculture tank with internal circulating water, which has at least the following advantages compared with the prior art:

[0018] The water pump is started, drawing water and fish waste from the tank through the permeable trough into the pump and out through the outlet pipe. The water flows into the filter box, which contains filter cotton that traps fish waste and other impurities. The filtered water then flows out through the drip hole into the first culture chamber, and subsequently through the second and third culture chambers. These chambers contain nitrifying bacteria culture blocks, such as ceramic rings, which decompose harmful substances in the water, improving filtration efficiency. The filtered water is then sprayed out from the hollow return water rack, pushing fish waste from the bottom towards the baffle. This, combined with the suction from the permeable trough, draws the fish waste into the pump, further enhancing filtration. The water circulates within the tank, ensuring uniform oxygen levels and facilitating fish farming. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Please see Figure 1-4 This utility model provides a technical solution: a housing 1, with reinforcing ribs 2 fixedly connected to the top of the housing 1, a water pump 3 fixedly installed inside the housing 1, and a water outlet pipe 4 fixedly connected to the outlet of the water pump 3; a filtration mechanism 5, disposed on the housing 1, for circulating and filtering the water inside the housing 1; and a control mechanism 6, disposed on the housing 1, for controlling the operation of the equipment. The filtration mechanism 5 includes a filter box 501 fixedly connected to the top of the housing 1, the water outlet pipe 4 extending through the filter box 501 to the top of the filter box 501, and a return water pipe 508 fixedly connected to the side of the filter box 501 away from the water outlet pipe 4. A hollow return water rack 509 is fixedly connected to one end of the return water pipe 508, and the hollow return water rack 509 has evenly spaced water outlets 510 facing the water pump 3. Inside the filter box 501, near the upper part and below the outlet pipe 4, a filter box 502 is fixedly connected. Drip holes 503 are evenly distributed at the bottom of the filter box 502. The interior of the filter box 501 is divided into a first culture chamber 505, a second culture chamber 506, and a third culture chamber 507 by a baffle 504. An overflow port 511 is provided on the upper part of the surface of the filter box 501. The highest point of the baffle 504 is lower than the lowest point of the filter box 502. A partition 512 is fixedly connected inside the box body 1, and a water-permeable groove 513 is provided on the surface of the partition 512.

[0027] Analysis of the above: The fish to be raised are placed in tank 1, and reinforcing ribs 2 are installed to improve the structural strength of tank 1. The water pump 3 is started, drawing water and fish waste from tank 1 through the permeable trough 513 into the pump 3, and then discharging it from the outlet pipe 4. The water in tank 1 flows into filter box 502, which contains filter cotton. Fish waste and other impurities are intercepted by the filter cotton. The filtered water is discharged from the drip hole 503 and flows into the first culture chamber 505, then sequentially through the second culture chamber 506 and the third culture chamber 507. The first culture chamber 505, second culture chamber 506, and third culture chamber 507 contain nitrifying bacteria culture blocks such as ceramic rings. These nitrifying bacteria decompose harmful substances in the water, improving the filtration effect. Filtered water is sprayed out from the hollow return water rack 509, pushing fish waste at the bottom towards the baffle 512. This, combined with the suction at the permeable trough 513, draws the fish waste into the water pump 3, improving the filtration effect. The water circulates within the tank 1, ensuring uniform oxygen levels and facilitating fish farming. The filter box 501, located above the tank 1, also provides hiding space for the fish, preventing them from being startled. An overflow outlet 511 is provided; if the filter box 501 becomes clogged, water will overflow from the overflow outlet 511, preventing leakage.

[0028] Example 2:

[0029] Please see Figure 1-4 This utility model provides a technical solution based on Embodiment 1: The control mechanism 6 includes a controller 608 fixedly connected to one side of the filter box 501. Inside the box 1, a level gauge 604 is fixedly connected to the side of the partition 512 near the water pump 3. A water supply pipe 602 is fixedly installed on the surface of the box 1. A solenoid valve 601, electrically connected to the controller 608, is fixedly connected to the water supply pipe 602. A reversing valve 606, electrically connected to the controller 608, is fixedly installed on the water outlet pipe 4. A drain pipe 607 is connected to the reversing valve 606. A temperature sensor 605 and a heating rod 603 are fixedly connected inside the box 1. The signal output terminal of the temperature sensor 605 is electrically connected to the signal input terminal of the controller 608, and the signal output terminal of the controller 608 is electrically connected to the signal input terminal of the heating rod 603.

[0030] Analysis of the above: The water level in tank 1 is monitored by level gauge 604. When the water level is low, controller 608 controls solenoid valve 601 to open, allowing external water to flow into tank 1 through water supply pipe 602, thus replenishing the water supply to tank 1. Controller 608 controls reversing valve 606 to reverse the flow, allowing water in tank 1 to be discharged through drain pipe 607, cooperating with solenoid valve 601 to achieve water exchange in tank 1. Heating rod 603 heats the water in tank 1, maintaining a stable water temperature conducive to fish growth. A retaining ring 8 is installed on reinforcing rib 2 to secure the return water pipe 508.
