Description

Technical Field

[0001] This utility model belongs to the field of aquaculture equipment technology, specifically referring to a loach farming device with built-in purification function. Background Technology

[0002] In loach farming, water quality is a core factor affecting their survival and growth. Current loach farming equipment has some shortcomings, such as:

[0003] 1. Traditional aquaculture equipment lacks an effective water purification structure. Pollutants such as loach excrement and uneaten feed are easily deposited in the water. Long-term accumulation will lead to eutrophication of the water, breed harmful microorganisms, and increase the risk of loach diseases.

[0004] 2. In most aquaculture devices, the oxygen supply system and purification system are independent and difficult to coordinate. The oxygen supply can only increase dissolved oxygen in the surface layer or local areas of the water, and cannot be precisely applied to the purification area (such as the area around the filter layer). As a result, the nitrifying bacteria required for purification have reduced activity due to lack of oxygen, which greatly reduces the purification efficiency. At the same time, it is difficult to meet the dissolved oxygen requirements of loaches feeding on debris in the purification area. In the end, frequent water changes are required to maintain water quality, which increases aquaculture costs and adds to the operational burden.

[0005] To address this issue, a loach farming device with built-in purification function is proposed. Utility Model Content

[0006] The technical problem this invention aims to solve is that traditional loach farming devices have weak water purification capabilities, are prone to pollutant deposition, and have difficulty linking the oxygen supply system with the purification device, resulting in low purification efficiency, uneven dissolved oxygen distribution, and the need for frequent water changes.

[0007] To achieve the above functions, the technical solution adopted by this utility model is as follows: A loach farming device with built-in purification function includes a bottom tank and a connecting tank fixedly installed at the upper end of the bottom tank. A top cover is snapped onto the upper end of the connecting tank, and an exhaust port is fixedly connected to the upper end of the top cover. A filter layer is fixedly installed inside the connecting tank, and the filter layer divides the inside of the connecting tank into upper and lower cavities. A driving component for realizing water circulation inside the upper and lower cavities is provided on the side wall of the connecting tank. An oxygen generating component for supplying oxygen to the inside of the connecting tank is provided on the side wall of the bottom tank.

[0008] Furthermore, the driving assembly includes a circulation pump fixedly mounted on the side wall of the connecting groove, and the upper and lower ends of the circulation pump are fixedly connected to an outlet pipe and a suction pipe, with the other end of the outlet pipe connected to the upper cavity inside the connecting groove and the other end of the suction pipe connected to the lower cavity inside the connecting groove.

[0009] Furthermore, an annular pipe connected to the water outlet pipe is fixedly installed inside the connecting groove, and multiple water outlet holes are fixedly arranged in an annular array inside the annular pipe.

[0010] Furthermore, the filter layer comprises three layers: upper, middle, and lower, which are respectively biochemical cotton, ceramic rings, and zeolite. A baffle is snapped onto the other side wall of the connecting groove, and the filter layer can be removed by opening the baffle.

[0011] Furthermore, the oxygen generating assembly includes an oxygen generator fixedly mounted on the side wall of the bottom tank and located below the water suction pipe. The output end of the oxygen generator is connected to an oxygen supply pipe, and the other end of the oxygen supply pipe passes through the bottom tank and is connected to the bottom wall of the connecting tank.

[0012] Furthermore, a one-way valve is provided at the connection between the connecting groove and the oxygen supply pipe to prevent water backflow.

[0013] The beneficial effects of this utility model by adopting the above structure are as follows:

[0014] 1. The circulating pump drives the water to flow in a closed loop between the upper and lower chambers of the connecting tank, sending pollutants to the three-layer filter layer of "biochemical cotton + ceramic ring + zeolite". The biochemical cotton intercepts large particles, the ceramic ring decomposes harmful substances, and the zeolite adsorbs nitrogen and phosphorus, achieving gradient purification, effectively reducing pollutant deposition, reducing the risk of anaerobic putrefaction in the water, and maintaining stable water quality without frequent water changes.

[0015] 2. The oxygen generator precisely supplies oxygen to the lower chamber below the filter layer through the oxygen supply pipe. This activates the activity of nitrifying bacteria on the ceramic rings, enhances purification efficiency, and increases dissolved oxygen in the purified water, allowing loaches to feed on debris more actively in this area. At the same time, the one-way valve at the oxygen supply pipe connection prevents water backflow, avoids damage to the oxygen generator, and ensures the stable operation of the oxygen supply and purification linkage system.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] like Figures 1 to 4 As shown, in order to achieve the above functions, the technical solution adopted by this utility model is as follows: A loach farming device with self-purification function includes a bottom tank 1, a connecting groove 2 is fixedly provided at the upper end of the bottom tank 1, a top cover 3 is snapped onto the upper end of the connecting groove 2, an exhaust port 4 is fixedly connected to the upper end of the top cover 3, a filter layer 12 is fixedly provided inside the connecting groove 2, the filter layer 12 divides the inside of the connecting groove 2 into upper and lower cavities, a driving component for realizing water circulation inside the upper and lower cavities is provided on the side wall of the connecting groove 2, and an oxygen generating component is provided on the side wall of the bottom tank 1.

[0025] like Figures 1 to 4As shown, the driving assembly includes a circulation pump 6 fixed to the side wall of the connecting groove 2. The upper and lower ends of the circulation pump 6 are fixedly connected to an outlet pipe 7 and a suction pipe 8. The other end of the outlet pipe 7 is connected to the upper cavity inside the connecting groove 2, and the other end of the suction pipe 8 is connected to the lower cavity inside the connecting groove 2. An annular pipe 11 connected to the outlet pipe 7 is fixedly installed inside the connecting groove 2. Multiple outlet holes 14 are fixedly arranged in an annular array inside the annular pipe 11. The filter layer 12 includes three layers: upper, middle, and lower. The upper, middle, and lower layers are biochemical cotton, ceramic rings, and zeolite, respectively. A baffle 5 is snapped onto the other side wall of the connecting groove 2. Opening the baffle 5 allows the filter to be opened. When the filter layer 12 is removed, in actual use, the operator first injects aquaculture water into the connecting tank 2 and releases loaches, starts the circulation pump 6, and the circulation pump 6 draws water from the lower cavity through the suction pipe 8, delivers it to the annular pipe 11 through the outlet pipe 7, and then flows evenly into the upper cavity through the outlet hole 14. The water permeates downward through the filter layer 12, and is successively filtered by biochemical cotton to intercept large particles of impurities, ceramic rings to decompose harmful substances, and zeolite to adsorb nitrogen and phosphorus to achieve gradient purification. After purification, the water falls into the lower cavity to form a closed loop flow, reducing the deposition of pollutants and eliminating the need for frequent water changes. When the filter layer 12 needs to be cleaned or replaced, it can be removed by opening the baffle 5, making the operation convenient.

[0026] Example 2:

[0027] Based on Example 1, such as Figures 1 to 4 As shown, an oxygen generating assembly is installed on the side wall of the bottom tank 1. The oxygen generating assembly includes an oxygen generator 9 fixed on the side wall of the bottom tank 1 and located below the water suction pipe 8. The output end of the oxygen generator 9 is connected to an oxygen supply pipe 10. The other end of the oxygen supply pipe 10 passes through the bottom tank 1 and connects to the bottom wall of the connecting tank 2. A one-way valve 13 is installed at the connection between the connecting tank 2 and the oxygen supply pipe 10 to prevent backflow of water. In actual use, the circulating pump 6 drives the water circulation and purification while starting the oxygen generator 9. Oxygen is delivered to the lower cavity of the connecting tank 2 through the oxygen supply pipe 10, which not only activates the activity of nitrifying bacteria on the ceramic ring to enhance purification, but also increases the dissolved oxygen in the water, allowing the loach to feed actively. The one-way valve 13 can prevent backflow of water from damaging the oxygen generator 9 and ensure stable linkage. During the breeding process, the exhaust port 4 promptly discharges volatile gases to maintain the internal pressure balance of the device.
