Abstract
Description
Technical Field
[0001] This utility model relates to the field of aquaculture technology, specifically to a recirculating aeration device for salmon farming. Background Technology
[0002] In aquaculture, salmon, as a high-value fish, has very high requirements for water quality during its cultivation. Recirculating aquaculture systems (RAS) can effectively control water quality, reduce disease incidence, and improve farming efficiency. However, existing RAS aeration equipment mostly adopts a centralized aeration method. This method typically sets up one or several centralized aeration points in the water body, injecting oxygen into these points to increase the dissolved oxygen level of the entire water body. However, centralized aeration has some problems, such as uneven oxygen distribution, easily forming hyperoxygenated areas near the aeration points, while areas far from the aeration points suffer from insufficient oxygen supply. In addition, the aeration efficiency of centralized aeration equipment is relatively low, which cannot meet the farming needs of fish such as salmon that have high dissolved oxygen requirements.
[0003] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a recirculating aeration device for salmon farming. Utility Model Content
[0004] The purpose of this invention is to provide a recirculating aeration device for salmon farming to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A technical solution for a recirculating aeration equipment for salmon farming includes a circulating pump. The input end of the circulating pump is connected to an inlet tee, and inlet pipes are installed on both sides of the inlet tee. The output end of the circulating pump is connected to a filter, and the tail end of the filter is connected to an outlet pipe. An outlet tee is installed at the tail end of the outlet pipe, and branch pipes are installed on both sides of the outlet tee. A secondary tee is installed at the tail end of the branch pipe, and circulating pipes are installed on both sides of the secondary tee. A water / air connector is connected to the tail end of the circulating pipe, and a miniature air pump is installed on the water / air connector. A collection pipe is connected to the bottom of the water / air connector, and an oxygenation head is connected to the tail end of the collection pipe.
[0007] As a preferred technical solution, an inlet control valve is installed on the inlet pipe, which is used to control the water flow rate of the inlet pipe.
[0008] As a preferred technical solution, the filter has a multi-layer filtration structure, including a coarse filtration layer and a fine filtration layer. The coarse filtration layer is used to remove larger impurities in the water, while the fine filtration layer is used to further remove tiny particles in the water, ensuring the cleanliness of the water.
[0009] As a preferred technical solution, the circulation pipe is equipped with a circulation valve, and multiple sets of circulation valves are provided to meet the needs of multi-mode decentralized oxygenation.
[0010] As a preferred technical solution, the oxygenation head has a porous structure design, which can evenly disperse oxygen into the water, thereby improving oxygenation efficiency and ensuring uniform oxygen distribution in the salmon farming environment.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This invention relates to a recirculating aeration device for salmon farming. The included miniature air pump enables decentralized oxygenation of the water, effectively avoiding the uneven oxygen distribution problem associated with centralized aeration. By installing a circulation valve on the circulation pipe, the distribution of water flow and oxygen can be flexibly controlled, thus meeting the different dissolved oxygen requirements of different farming areas. Furthermore, the porous aeration head design ensures that oxygen is evenly dispersed into the water, further improving aeration efficiency and providing a more suitable growth environment for salmon.
[0013] This invention not only improves oxygenation efficiency but also optimizes oxygen distribution, ensuring the healthy growth of salmon and thus increasing both yield and quality in aquaculture. Attached Figure Description

[0017] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.
[0018] like Figure 1, Figure 2 As shown, this utility model provides a technical solution for a recirculating aeration equipment for salmon farming: it includes a circulating pump 1, the input end of which is connected to an inlet tee 11. Inlet pipes 12 are respectively installed on both sides of the inlet tee 11, and inlet control valves 13 are installed on the inlet pipes 12 to control the water flow rate. A filter 14 is connected to the output end of the circulating pump 1. The filter 14 has a multi-layer filtration structure, including a coarse filtration layer and a fine filtration layer, used to remove larger impurities and small particles from the water, ensuring water cleanliness.
[0019] The filter 14 is connected to a water outlet pipe 15 at its tail end, and a water outlet tee 2 is installed at the tail end of the water outlet pipe 15. Diverter pipes 21 are installed on both sides of the water outlet tee 2, and secondary tee 22 is installed at the tail end of each diverter pipe 21. Circulation pipes 23 are installed on both sides of each secondary tee 22, and a water / air connector 25 is connected to the tail end of each circulation pipe 23. A miniature air pump 26 is installed on the water / air connector 25 for injecting oxygen into the water.
[0020] The bottom of the water / air connector 25 is connected to a manifold 27, and the tail end of the manifold 27 is connected to an oxygenation head 28. The oxygenation head 28 has a porous structure design, which can evenly disperse oxygen into the water, thereby improving oxygenation efficiency and ensuring uniform oxygen distribution in the salmon farming environment.
[0021] The circulation pipe 23 is equipped with multiple circulation valves 24 to accommodate various decentralized oxygenation methods as needed. By adjusting the opening and closing states of the circulation valves 24, the distribution of water flow and oxygen can be flexibly controlled to meet the different dissolved oxygen requirements of different aquaculture areas.
[0022] In practical applications, the circulation pump 1 draws water from the water body through the inlet tee 11, filters it through multiple layers of the filter 14, and then distributes it to the various circulation pipes 23 through the outlet tee 2 and the diversion pipe 21. The micro air pump 26 injects oxygen into the water, which is then delivered to the aerator 28 through the water-air connector 25 and the main pipe 27. The aerator 28 evenly disperses the oxygen in the water, ensuring uniform oxygen distribution in the salmon farming environment.
[0023] This utility model of a circulating water oxygenation equipment for salmon farming can effectively solve the problem of uneven oxygen distribution caused by centralized oxygenation, improve oxygenation efficiency, optimize oxygen distribution, and provide a more suitable growth environment for salmon, thereby improving the yield and quality of aquaculture.
