Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to an oxygenator for marine product cultivation. Background Art

[0002] Aerators play a vital role in seafood farming. They are used to increase the oxygen content in water, improve water quality conditions, and promote the growth of seafood farming objects.

[0003] Impeller aerators usually include an aerator head, a buoy and an impeller at the bottom. The buoy enables the aerator to float stably on the water surface and maintain an appropriate depth and position. The motor in the aerator head can drive the impeller to rotate, generate water flow, and make the water body fully contact with the air, thereby increasing the dissolved oxygen content in the water.

[0004] However, aerators can only achieve single-point oxygenation, and oxygen-rich water containing dissolved oxygen is always concentrated near the impeller, which results in a very small oxygenation range and low oxygenation efficiency. In order to solve the above problems, we propose an aerator for seafood farming. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 The utility model provides a technical solution of an aerator for seafood farming: it includes an aerator head 1, a motor is arranged in the aerator head 1, a rotating impeller 2 is connected to the bottom of the aerator head 1, the motor can drive the impeller 2 to rotate, so as to realize the oxygenation of seawater, an oxygen exchange component 3 is also arranged at the bottom of the aerator head 1, a water inlet end of the oxygen exchange component 3 passes through the bottom of the impeller 2 and extends to the lower part of the impeller 2, so as to absorb the seawater around the impeller 2.

[0026] The oxygen exchange component 3 is evenly provided with support pipes 4 for installing buoys. The buoys support the aerator through the support pipes 4. The support pipes 4 are tubular components. The support pipes 4 are connected to the water outlet end of the oxygen exchange component 3. The seawater absorbed by the oxygen exchange component 3 flows to the support pipes 4 through the water outlet end. The end of the support pipes 4 away from the aerator head 1 is connected to an oxygen exchange pipe 5 extending underwater. The water outlet end of the oxygen exchange pipe 5 is extended to the deep seawater, so that the oxygen-rich seawater absorbed by the oxygen exchange component 3 can be transported to the deep seawater away from the impeller 2 through the support pipes 4 and the oxygen exchange pipes 5, thereby increasing the oxygenation range and efficiency.

[0027] Specifically, the bottom of the oxygen exchange component 3 is connected to a first rotating joint 6, and the bottom of the first rotating joint 6 is connected to a rotating pipe 7 extending to the lower part of the impeller 2. Oxygen-rich seawater is provided to the oxygen exchange component 3 through the rotating pipe 7 via the first rotating joint 6. The rotating pipe 7 is fixedly connected to the inner wall of the impeller 2 through the connecting piece 13, so that the impeller 2 body can rotate with the rotation of the rotating pipe 7. A driving group for driving the impeller 2 to rotate is provided at the bottom of the aerator head 1. The driving group is connected to the rotating pipe 7. By providing the driving group, the rotating pipe 7 can be rotated. The rotation of the rotating pipe 7 can drive the impeller 2 to rotate, so that the seawater generates water flow, and the water body is fully in contact with the air, thereby increasing the dissolved oxygen content in the water. By providing the first rotating joint 6, the rotating pipe 7 can drive the impeller 2 to rotate while absorbing seawater.

[0028] Specifically, the driving group includes a bearing seat 81 connected to the oxygen exchange component 3, and a rotating optical axis 82 is passed through the bearing seat 81. The optical axis 82 can rotate in the bearing seat 81, and a first gear 83 is fixedly connected to the bottom of the optical axis 82. The motor in the aerator head can drive the optical axis 82 to rotate, and then drive the first gear 83 to rotate. The outer wall of the rotating pipe 7 is fixedly connected to a second gear 84 that meshes with the first gear 83. As the first gear 83 rotates, the second gear 84 can drive the rotating pipe 7 to rotate, and then the impeller 2 rotates.

[0029] Specifically, a filter screen 11 is fixedly connected to the water inlet end of the rotating pipe member 7 to prevent foreign matter from entering the waterway through the water inlet end of the rotating pipe member 7 and causing blockage.

[0030] Specifically, the oxygen exchange component 3 includes a water distribution tank 31 and a circulation pump 32, both of which are fixedly connected to the bottom of the aerator head 1. The bottom of the water distribution tank 31 is fixedly connected with an inlet pipe 33 for sucking oxygen-rich seawater around the impeller 2. The water inlet end of the circulation pump 32 is connected to the inlet pipe 33, and the water outlet end of the circulation pump 32 is connected to the water inlet of the water distribution tank 31. The circulation pump 32 is started so that the circulation pump 32 can suck oxygen-rich seawater around the impeller 2 through the inlet pipe 33 and provide it to the water distribution tank 31. The supporting pipes 4 are all connected to the outlet of the water distribution tank 31. The oxygen-rich seawater can be provided to the supporting pipes 4 through the water distribution tank 31, and is transported to the deep seawater away from the impeller 2 through the oxygen exchange pipe 5, thereby increasing the oxygenation range and efficiency.

[0031] Specifically, the support pipe 4 is connected to the oxygen exchange component 3 through the rotating component 9. By providing the rotating component 9, the support pipe 4 can be rotated, and the oxygen exchange pipe 5 can be driven to rotate around the support pipe 4, thereby preventing the oxygen exchange pipe 5 from being supported on the ground when the aerator is moved out of the sea and placed on land, thereby preventing the oxygen exchange pipe 5 from being damaged.

[0032] Specifically, the rotating assembly 9 includes a second rotating joint 91, the water inlet end of the second rotating joint 91 is fixedly connected to the water outlet end of the oxygen exchange assembly 3, and the support pipe 4 is fixedly connected to the water outlet end of the second rotating joint 91, so that the oxygen exchange assembly 3 and the support pipe 4 can not only transport oxygen-rich seawater, but also rotate the support pipe 4. A locking member 92 connected to the side wall of the second rotating joint 91 is provided on the support pipe 4, which is used to fix the support pipe 4 to prevent the support pipe 4 from rotating when the aerator is working.

[0033] Specifically, the locking member 92 includes a rotating plate 921, which is fixedly sleeved on the outer wall of the supporting pipe 4. A bolt 922 is passed through the rotating plate 921. A threaded hole matching the bolt 922 is provided on the second rotating joint 91. By screwing the bolt 922 into the threaded hole, the rotating plate 921 is fixed, and then the supporting pipe 4 is fixed to prevent the supporting pipe 4 from rotating.

[0034] Specifically, the water outlet end of the oxygen exchange pipe 5 is connected to an aeration plate 12, and a plurality of water outlet holes are provided on the aeration plate 12 to improve the dissolution efficiency of oxygen in seawater far away from the impeller 2 and deep seawater, and increase the dissolved oxygen content in the seawater.

[0035] Working principle:

[0036] When in use, the buoy supports the aerator through the supporting pipe 4, starts the motor in the aerator head 1, rotates the optical axis 82, and then drives the first gear 83 to rotate. As the first gear 83 rotates, the second gear 84 can drive the rotating pipe 7 to rotate, and then the impeller 2 rotates, so that the water body is in full contact with the air, thereby increasing the dissolved oxygen content in the water.

[0037] The circulation pump 32 is started so that the circulation pump 32 can absorb oxygen-rich seawater around the impeller 2 through the water inlet pipe 33 and provide it to the water distribution tank 31. The oxygen-rich seawater can be provided to the support pipe 4 through the water distribution tank 31, and transported to the deep seawater far away from the impeller 2 through the oxygen exchange pipe 5, thereby increasing the oxygenation range and efficiency.
