Description

Technical Field

[0001] This utility model relates to a high-density oxygen-enriched aquaculture equipment. Background Technology

[0002] In the process of aquaculture, it is necessary to carry out oxygen enrichment operations and maintain the hygiene and safety of the aquaculture environment through water circulation.

[0003] Existing aquaculture equipment typically uses multi-layer filtration components to filter water. While this can purify circulating water, it requires regular replacement of the filtration components, which not only reduces the user experience but also increases operating costs. Utility Model Content

[0004] This invention provides a high-density oxygen-enriched aquaculture equipment.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a high-density oxygen-enriched aquaculture equipment, including a water circulation mechanism, wherein the water circulation mechanism includes a water inlet component, a filter component, a drainage component and a backwashing component;

[0006] The water inlet assembly includes a water inlet pipe and a first three-way valve;

[0007] The filter assembly includes a housing, which is semi-circular. Inside the housing are a first filter, a second filter, and a third filter, all of which are semi-circular. The centers of the first, second, and third filters are all located at the center of the housing. The radii of the first, second, and third filters gradually decrease, as do the mesh sizes. A cover plate, which is circular, has a diameter equal to the diameter of the housing. The edge of the cover plate connects to the edge of the arc surface of the housing. A through hole is located at the center of the cover plate, and the diameter of the through hole is smaller than the diameter of the third filter.

[0008] The drainage assembly includes a water outlet pipe and a second three-way valve. One end of the water outlet pipe is sealed to the through hole of the cover plate, and the second three-way valve is installed on the water outlet pipe.

[0009] The backwashing assembly includes a main water pipe, a secondary water pipe, and two outlet boxes. There are two main water pipes, each connected to an outlet box. The outlet boxes are mounted on a cover plate, with the two outlet boxes located on either side of the outlet pipes. The outlet boxes are connected to the interior of the housing through the cover plate. The edges of the first and second filter screens are located directly below the outlet boxes. The secondary water pipe is connected to a second three-way valve.

[0010] Preferably, a drain pipe is connected to the first three-way valve, and a valve is provided on the drain pipe.

[0011] Preferably, the connection between the cover plate and the water outlet box is provided with several water holes.

[0012] The beneficial effects of this utility model are that the high-density oxygen-enriched aquaculture equipment uses a first filter screen, a second filter screen, and a third filter screen with gradually decreasing mesh size from the outside to the inside to filter the circulating water. This effectively removes particulate impurities such as mud and sand from the water, reduces the purification pressure of subsequent processes, extends the service life of subsequent processes, reduces operating costs and maintenance frequency, and also has its own backwashing function. It is convenient to use and highly practical. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] like Figure 1 As shown, a high-density oxygen-enriched aquaculture equipment includes a water circulation mechanism, which includes an inlet component, a filter component, a drain component, and a backwashing component.

[0018] The water inlet assembly includes a water inlet pipe 1 and a first three-way valve 2;

[0019] The filter assembly includes a housing 3, which is semi-circular. Inside the housing 3 are a first filter 4, a second filter 5, and a third filter 6. All three filters are semi-circular, with their centers located at the center of the housing 3. The radii and mesh sizes of the filters gradually decrease. A cover plate 12, which is circular and has a diameter equal to the diameter of the housing 3, is provided on the housing 3. The edge of the cover plate 12 connects to the edge of the arc surface of the housing 3. A through hole, smaller in diameter than the third filter 6, is located at the center of the cover plate 12.

[0020] The drainage assembly includes a water outlet pipe 7 and a second three-way valve 8. One end of the water outlet pipe 7 is sealed to the through hole of the cover plate 12, and the second three-way valve 8 is installed on the water outlet pipe 7.

[0021] The backwashing assembly includes a main water pipe 9, a secondary water pipe 10, and two water outlet boxes 11. There are two main water pipes 9, each connected to a water outlet box 11. The water outlet boxes 11 are mounted on a cover plate 12, and the two water outlet boxes 11 are located on either side of the water outlet pipe 7. The water outlet boxes 11 are connected to the interior of the housing 3 through the cover plate 12. The edges of the first filter screen 4 and the second filter screen 5 are located directly below the water outlet boxes 11. The secondary water pipe 10 is connected to the second three-way valve 8.

[0022] Preferably, a drain pipe is connected to the first three-way valve 2, and a valve is provided on the drain pipe.

[0023] Preferably, the connection between the cover plate 12 and the water outlet box 11 is provided with several water holes.

[0024] During normal water circulation, the first three-way valve 2 is in the state where the inlet pipe 1 is connected to the housing 3, and the second three-way valve 8 is in the state where the outlet pipe 7 is connected to the inside of the housing 3. Water flows into the housing 3 from the inlet pipe 1 and passes through the first filter screen 4, the second filter screen 5, and the third filter screen 6 in sequence for filtration. The mesh size of the first filter screen 4, the second filter screen 5, and the third filter screen 6 gradually decreases. This allows for the stratified filtration of impurities with larger and smaller particle diameters, relieving filtration pressure and improving filtration efficiency. The water is then discharged to the subsequent purification process through the outlet pipe 7, which greatly reduces the purification pressure of the subsequent purification process and extends the service life of the components in the subsequent purification process.

[0025] After a period of use, the filtration equipment is backwashed. The first three-way valve 2 is adjusted to connect the drain pipe to the inside of the housing 3, and the second three-way valve 8 is adjusted to connect the auxiliary water pipe 10 to the inside of the housing 3. Then, clean water is introduced into the main water pipe 9, and the water flow will enter the housing 3 in three paths. Two of the water flow enters the two water outlet boxes 11. In fact, the function of the water outlet box 11 is similar to that of a shower head, mainly to increase the water flow area, that is, to increase the rinsing area. The other water flow enters the housing 3 from the auxiliary water pipe 10. The three water flows rinse the first filter screen 4, the second filter screen 5, and the third filter screen 6 respectively. The impurities attached to the water-facing surfaces of the first filter screen 4, the second filter screen 5, and the third filter screen 6 will be washed off by the water flow and discharged from the drain pipe, thus achieving the purpose of cleaning impurities, ensuring the smooth operation of the filtration, reducing the chance of clogging, and ensuring filtration efficiency.

[0026] Compared with existing technologies, this high-density oxygen-enriched aquaculture equipment uses a first filter screen 4, a second filter screen 5, and a third filter screen 6 with gradually decreasing mesh size from the outside in to filter the circulating water. This effectively removes particulate impurities such as silt from the water, reduces the purification pressure of subsequent processes, extends the service life of subsequent processes, reduces operating costs and maintenance frequency, and also has its own backwashing function, making it convenient to use and highly practical.

[0027] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
