Description

Technical Field

[0001] This utility model relates to the technical field of factory-scale recirculating aquaculture teaching, specifically a factory-scale recirculating aquaculture teaching demonstration model device. Background Technology

[0002] Traditional aquaculture methods, such as ponds, cages, large water surfaces, and tidal flats, suffer from disadvantages including large land occupation, limited aquaculture areas, environmental pollution, soil eutrophication, and susceptibility to geographical and climatic conditions. These disadvantages have become bottlenecks restricting the green and sustainable development of my country's aquaculture industry. With the increasing demand for aquaculture, large-scale, intensive, mechanized, intelligent, and standardized operations have become new goals. Factory-style recirculating aquaculture systems (RAS) represent its core and main development direction. Compared with traditional aquaculture methods, RAS offers advantages such as water conservation, environmental friendliness, high yield, and sustainability.

[0003] Traditional aquaculture technology teaching is mostly conducted outdoors, requiring large areas and inconvenient for travel; this is not conducive to teaching aquaculture techniques, nor to visiting farms and collecting experimental data. Therefore, we propose a factory-style recirculating aquaculture teaching and demonstration model device. Utility Model Content

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0020] Please see Figure 1-5In this embodiment of the utility model, a teaching and demonstration model device for factory-scale recirculating aquaculture includes a support platform 16. The top of the support platform 16 is equipped with a constant temperature machine 1, a protein separator 2, an oxygen cone 3, a deaeration tank 4, a fish pond 5, a vertical flow sedimentation tank 6, a biological filter tank 7, and a PLC control display screen 13. There are four fish ponds 5 and four vertical flow sedimentation tanks 6, and the fish ponds 5 and vertical flow sedimentation tanks 6 are arranged in a one-to-one correspondence. The support platform 16 is located between the constant temperature machine 1 and the deaeration tank 4 and is equipped with a microfilter 11, a germicidal lamp 14, and a water pump 15. The lower part of the support platform 16 is equipped with a Roots blower 8, a PLC control cabinet 9, and a tailwater treatment tank 10.

[0021] The biological filter tank 7 is equipped with a sensor assembly 12, which includes a water quality monitoring sensor and a liquid level sensor.

[0022] Water pump: Variable frequency control, the water pump flow rate is adjusted online in real time according to demand.

[0023] Microfilter 11: It filters feces, feed residue, etc. in fish pond water, and can effectively remove more than 95% of feed residue and feces in the water.

[0024] Germicidal lamp 14: Sterilizes the water in the biological tank.

[0025] Protein separator 2: Uses the surface tension of bubbles to separate proteins in water.

[0026] Deaeration tank 4: It can effectively remove harmful gases such as carbon dioxide and increase dissolved oxygen in water.

[0027] Biological filter tank 7: biological aeration and physical filtration sedimentation of water filtered by microfiltration machine.

[0028] Thermostat 1: It can control and adjust the water temperature according to the temperature required by different aquaculture products.

[0029] Oxygen cone 3: Under the condition of thorough gas-liquid mixing, the pressure is increased to force the gas to overcome the surface tension of water and passively dissolve, so that oxygen is fully dissolved in the water and the oxygen content in the water is increased.

[0030] Tailwater treatment tank 10: Collects and settles the feces and feed residue discharged from the backwash of the microfiltration machine, as well as the sewage from the protein separator and vertical flow sedimentation tank.

[0031] Roots blower 8: Aeration treatment of aquaculture water filtered by microfiltration machine can reduce the ammonia nitrogen content in the water.

[0032] Liquid level sensor: controls the start and stop of the water pump by controlling the high and low liquid levels.

[0033] Water quality monitoring sensors: monitor the pH, dissolved oxygen, pH, and ammonia nitrogen content of the treated water.

[0034] Fish waste and food residue are filtered and settled in a vertical flow sedimentator, with impurities discharged into the effluent treatment tank through the drain outlet. The filtered water flows to a microfiltration unit for secondary filtration, removing fine impurities. These impurities are then discharged into the effluent treatment tank through the microfiltration unit's collection tank. The filtered water then undergoes sterilization treatment with a sterilizing lamp. The water is then pumped in two directions: one direction passes through a protein skimmer, using the surface tension of air bubbles to separate proteins and purify the water. The separated impurities are discharged into the effluent treatment tank through the drain outlet, and the purified water flows into the microfiltration unit. The other direction enters a deaeration tank to remove carbon dioxide before flowing into a biological filter. Aeration by a Roots blower effectively reduces ammonia nitrogen levels in the water. The water then flows into a thermostat to heat the water and ensure normal growth of the farmed organisms. Finally, the water flows into an oxygen concentrator, which can be connected to an external oxygen generator or liquid oxygen tank for efficient oxygenation. The water then flows back into the fishpond, completing a cycle.

[0035] All equipment and instruments are connected to the PLC control cabinet via cables, and the data collected by the probes is fed back to the PLC module in the control cabinet for data processing.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
