[0031] 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.

[0032] The purpose of this utility model is to provide a land-based recirculating aquaculture tank fish toilet to solve the problems existing in the prior art. It solves the problem that the fish toilets in the prior art are prone to mismatch with the fish fry due to their uniform through holes, which can easily cause fish to escape through the through holes or cause fecal blockage.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1 to 6As shown, this utility model provides a fish toilet for a land-based recirculating aquaculture system, including a fish toilet body. The fish toilet body has a cylindrical structure and is installed inside the land-based recirculating aquaculture system. One end of the fish toilet body is detachably connected to and communicates with a drain outlet at the bottom of the land-based recirculating aquaculture system. The outer wall of the fish toilet body exposed inside the land-based recirculating aquaculture system has arrayed through holes 4. The through holes 4 are used to trap fish fry and allow aquaculture pollutants to pass through. When the land-based recirculating aquaculture system drains, the fish excrement is concentrated at the bottom of the water body in the land-based recirculating aquaculture system, and enters the drain outlet and sewage pipe through the through holes 4 on the fish toilet body, and is then discharged into the sedimentation tank. This utility model discloses a land-based recirculating aquaculture tank fish toilet. Because the fish toilet body can be detachably installed at the drain outlet at the bottom of the land-based recirculating aquaculture tank, various types of fish toilet bodies can be manufactured to meet the excrement collection needs of fish of different sizes in the land-based recirculating aquaculture tank. Specifically, the through hole 4 on each fish toilet body has a different structure, and the corresponding fish toilet body can be selected and installed at the drain outlet. This solves the problem that the fish toilets in the prior art, due to their uniform through hole 4, are easy to cause mismatch with the farmed fish fry, easy for fish to escape through the through hole 4, or cause fecal blockage.

[0035] In this embodiment, the fish toilet body includes a connecting joint and a filter cylinder 3. The connecting joint is sealed to the drain outlet. For example, the connecting joint can be glued to the drain outlet with waterproof sealant, or a sealing ring can be fitted to squeeze into the drain outlet to achieve a sealed connection between the connecting joint and the drain outlet. The filter cylinder 3 is detachably installed on the connecting joint, preferably by a threaded connection, and is connected to the connecting joint. The filter cylinder 3 has through holes 4 arrayed on the outer wall exposed inside the land-based circulating water tank. Therefore, the filter cylinder 3 can be replaced individually according to different operating conditions.

[0036] In this embodiment, the connecting joint includes a mounting part 1 and an adapter part 2. The mounting part 1 is fixedly installed at the drain outlet and is sealed and connected to the drain outlet. For example, the mounting part 1 can be glued to the drain outlet with waterproof sealant, or a sealing ring can be fitted to squeeze into the drain outlet to achieve a sealed connection between the mounting part 1 and the drain outlet. One end of the adapter part 2 is detachably installed at the mounting part 1 and connected to the mounting part 1, and the other end is detachably connected to the filter cartridge 3 and connected to the filter cartridge 3. The adapter part 2 is used as an adapter structure, and the adapter part 2 can be replaced according to different filter cartridges 3 to match different installation requirements.

[0037] Preferably, the mounting part 1 has a straight cylindrical structure with openings at both ends, and is used for coaxial sealing insertion into the drain outlet, so that it can be more convenient to bond with waterproof sealant or fit a sealing ring to ensure that the mounting part 1 is sealed and connected at the drain outlet.

[0038] In this embodiment, the adapter 2 includes a first connecting section and a second connecting section. The structure of the first connecting section matches the structure of the mounting section 1 and is threadedly connected to the mounting section 1. The second connecting section is integrally formed with the first connecting section and coaxially connected. The structure of the second connecting section matches the structure of one end of the filter cartridge 3 and is inserted into the filter cartridge 3 to ensure that the adapter 2 can complete the connection between the mounting section 1 and the filter cartridge 3.

[0039] Preferably, a snap-fit ​​is provided between one end of the filter cylinder 3 and the second connecting section to ensure the firmness of the connection between the filter cylinder 3 and the second connecting section; preferably, the snap-fit ​​has a male end and a female end, the male end is an annular protrusion and the female end is an annular groove. After the filter cylinder 3 and the second connecting section are inserted and engaged, the annular protrusion can fit into the annular groove, so that the filter cylinder 3 and the second connecting section can be stably connected after being inserted and engaged.

[0040] In this embodiment, the radial cross-section of the second connecting section is larger than that of the first connecting section to ensure that the structure of the filter cartridge 3 is large enough, thereby improving the filtration efficiency.

[0041] In this embodiment, the installation unit 1 is equipped with multiple adapters 2. Each adapter 2 is prepared in advance according to the required breeding conditions. Each adapter 2 can be replaced and installed at the installation unit 1, so that it can be replaced according to different breeding conditions.

[0042] In this embodiment, the adapter 2 is equipped with multiple filter cartridges 3. Each filter cartridge 3 is prepared in advance according to the required aquaculture conditions. Each filter cartridge 3 can be replaced and installed at the adapter 2, so that it can be replaced according to different aquaculture conditions.

[0043] In one specific embodiment, the filter cylinder 3 is a straight cylindrical structure with one end open. The open end of the filter cylinder 3 is detachably connected to a connecting connector, for example, by threaded connection or snap-fit ​​connection. The outer peripheral wall of the filter cylinder 3 has through holes 4 arrayed. The shape of the through holes 4 includes, but is not limited to, straight strip, circle and polygon, to match different aquaculture conditions, achieve efficient sewage discharge and improve the adaptability of fish fry.

[0044] Any adaptive changes made according to actual needs are within the protection scope of this utility model.
