Description

Technical Field

[0001] This utility model relates to oxygenation devices, and more particularly to a microporous aeration disc specifically for liquid oxygen aeration. Background Technology

[0002] In aquaculture, dissolved oxygen in the recirculating aquaculture system directly affects the growth and development of aquatic organisms. Therefore, it is necessary to consider how to oxygenate the water flow to meet the needs of aquaculture. Among them, the aeration disc is an oxygenation device specifically designed for pure oxygen aeration. This device does not consume electricity and is powered entirely by the pressure of the liquid oxygen storage tank. The vaporized liquid oxygen is dispersed into micro-nano-sized bubbles through the micro-nano ceramic plate with extremely fine pores and enters the water body, increasing the water-air contact surface and thus improving the dissolved oxygen in the water.

[0003] When traditional aeration discs are installed at the bottom of aquaculture ponds, they are often easily corroded when faced with the complex water conditions of the ponds, resulting in a short overall service life. Furthermore, due to the limitations of the aeration discs' own structural design, the oxygen bubbles discharged through the aeration discs are of varying sizes, which cannot efficiently increase the dissolved oxygen concentration in the aquaculture ponds. To address these issues, this application proposes a solution. Summary of the Invention

[0004] Purpose of the utility model: The purpose of this utility model is to provide a microporous aeration disc specifically for liquid oxygen aeration, which can improve the efficiency of increasing dissolved oxygen concentration in aquaculture ponds and extend the service life of the aeration disc in aquaculture ponds.

[0005] Technical solution: The present invention provides a microporous aeration disc for liquid oxygen aeration, comprising a base and a ceramic plate disposed on the base. A sealed air chamber is provided between the base and the ceramic plate, and the air chamber is connected to an external air pipe through an opening. Micropores are uniformly disposed on the ceramic plate, and the pore diameter of the micropores is less than 1.5 micrometers.

[0006] The micropores on the ceramic plates have a diameter of less than 1.5 micrometers, which can further reduce the size of the oxygen bubbles discharged through the ceramic plates. Smaller oxygen bubbles can further improve the efficiency of oxygen dissolution in water within the aquaculture pond.

[0007] Preferably, the uniformity of the pore size of the micropores on the ceramic sheet is not less than 80%.

[0008] A pore size uniformity of no less than 80% ensures that the oxygen bubbles discharged through the ceramic plate are more uniform in size, further improving the oxygen dissolution efficiency in water.

[0009] Preferably, the base is made of an aluminum shell and is integrally molded.

[0010] After oxidation, the aluminum base will form a dense protective layer of aluminum oxide, which improves the corrosion resistance of the base, and the one-piece molded structure can improve the strength of the base.

[0011] Preferably, the outer surface of the base is provided with at least three layers of anti-corrosion coating.

[0012] The anti-corrosion layer further improves the overall corrosion resistance of the base, while protecting the dense protective layer of alumina.

[0013] Preferably, the air chamber is provided with an annular loop of not less than one layer, and a glue groove is provided at the center of the annular loop.

[0014] The loop design ensures that when oxygen enters the chamber, a gas loop is formed, buffering the impact force on the base and ceramic plates when the gas enters the chamber, making the ceramic plates bear the force evenly, and also improving the overall structural strength of the equipment and extending its service life.

[0015] Preferably, the adhesive groove is provided with adhesive for bonding and supporting the ceramic sheet.

[0016] The adhesive in the glue tank serves to bond and support the ceramic sheet, improving the firmness of the bond between the ceramic sheet and the base, and enhancing the overall structural strength of the equipment.

[0017] Preferably, the annular circuit is provided with an air inlet, which is directly opposite the opening.

[0018] The air inlet is designed to guide airflow, directing the oxygen entering the air chamber into different gas circuits and buffering the impact of the gas.

[0019] Preferably, the opening is provided with a 90° pagoda connector, which connects the opening to the external air pipe.

[0020] Compared to traditional plastic direct connectors, pagoda connectors are easier to distinguish between the front and back during equipment installation and commissioning, and they also have a longer service life and higher strength.

[0021] Preferably, the base is provided with a foot support at the bottom, and the foot support is provided with a rubber suction cup at the bottom.

[0022] The foot support design prevents the base from directly contacting the bottom of the aquaculture pond, avoiding friction between the base and the pond bottom when the base is moved, thus extending the base's service life. It also facilitates the cleaning and removal of dirt and debris accumulated between the base and the pond bottom during subsequent cleaning. The rubber suction cup design allows the base to firmly adhere to the bottom of the aquaculture pond under the action of water pressure and the weight of the aeration disc itself, preventing unnecessary movement of the aeration disc during daily use.

[0023] Beneficial effects: Compared with the prior art, this utility model has the following advantages:

[0024] (1) This utility model uses ceramic plates with a pore size of less than 1.5 micrometers and a pore size uniformity of not less than 80%, which further reduces the size of the oxygen bubbles discharged through the ceramic plates, so that the oxygen bubbles can be efficiently dissolved in the aquaculture pond, thereby improving the efficiency of increasing the dissolved oxygen concentration in the aquaculture pond.

[0025] (2) The gas chamber of this utility model adopts a ring circuit, which reduces the impact of gas on the base and ceramic plate when the gas enters the gas chamber, guides the gas to form a gas circuit, and improves the structural strength of the aeration disc.

[0026] (3) This utility model improves the overall corrosion resistance of the aeration disc and extends its service life by using an integrated aluminum shell structure and a multi-layer anti-corrosion coating.

[0027] (4) The present invention, through the design of foot support and rubber suction cup, on the one hand, meets the requirement that the aeration disc can be firmly set at the bottom of the aquaculture pond in daily work, and on the other hand, avoids wear caused by unnecessary movement of the bottom of the aeration disc and the bottom of the aquaculture pond, thus improving the service life of the aeration disc.

[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0034] See appendix Figures 1-4 The figure shows a microporous aeration disc for liquid oxygen aeration, which includes a base 1 and a ceramic plate 8 disposed on the base 1. A sealed air chamber is provided between the base 1 and the ceramic plate 8, and the air chamber is connected to an external air pipe through an opening 2.

[0035] The ceramic plate 8 is uniformly provided with micropores, the pore diameter of which is less than 1.5 micrometers, and the uniformity of the pore diameter is not less than 80%. This design can, on the one hand, further reduce the size of the oxygen bubbles discharged through the ceramic plate 8. By reducing the size of the oxygen bubbles, the rising speed of the oxygen bubbles in the water can be slowed down, allowing the oxygen bubbles to have more contact time with the water. At the same time, the same volume of oxygen is divided into smaller oxygen bubbles entering the water, which can also increase the contact area between oxygen and water. By increasing the contact area and contact time between oxygen bubbles and water, the oxygen bubbles can be fully dissolved in the water in the aquaculture pond, improving the oxygen dissolution efficiency in the water. On the other hand, it can also ensure that the size of the oxygen bubbles discharged through the ceramic plate 8 is more uniform, further improving the oxygen dissolution efficiency in the water.

[0036] An annular circuit 3 is provided in the gas chamber, and an air inlet 4 is provided on the annular circuit 3. The air inlet 4 is directly opposite the opening 2. This arrangement allows oxygen to enter the gas chamber without directly rushing to the bottom of the gas chamber, causing the ceramic plate 8 at the bottom of the gas chamber to bear high pressure. Instead, through the cooperation of the annular circuit 3 and the air inlet 4, the airflow is dispersed and guided to both sides and inside the air inlet 4, so that the instantaneous pressure of the oxygen entering the gas chamber decreases. After the gas chamber is filled, pressure is evenly applied to the ceramic plate 8, and the gas is discharged from the gas chamber through the micropores of the ceramic plate 8. This can improve the overall structural strength of the equipment and extend its service life.

[0037] A glue groove 5 is provided at the center of the ring circuit 3. The glue groove 5 contains glue, which can bond and support the ceramic sheet, thereby improving the firmness of the connection between the ceramic sheet and the base 1 and enhancing the overall structural strength of the equipment.

[0038] The opening is equipped with a 90° pagoda connector, which connects the opening to the external air pipe. Compared with traditional plastic direct connectors, the pagoda connector makes it easier to distinguish the front and back during equipment installation and commissioning, and it has a long service life and high strength.

[0039] Example 1: The base 1 is made of aluminum shell and is integrally molded. At the same time, three layers of anti-corrosion coating are provided on the outer surface of the base 1. The integrally molded aluminum shell structure can improve the overall strength of the base 1. After oxidation, the surface of the aluminum base 1 will form a dense protective layer of aluminum oxide. Combined with the anti-corrosion coating, it can further improve the overall anti-corrosion performance of the base 1. At the same time, the three layers of anti-corrosion coating can protect the dense protective layer of aluminum oxide when the base is placed at the bottom of the aquaculture pond and rubs against the bottom of the aquaculture pond, preventing damage caused by wear and increasing the service life of the base.

[0040] Example 2: The base 1 is equipped with a foot support 6 at its bottom, and a rubber suction cup 7 is installed at the bottom of the foot support 6. The foot support 6 can prevent the base 1 from directly contacting the bottom of the aquaculture pond, thus avoiding friction between the base 1 and the bottom of the aquaculture pond when the base 1 is moved, thereby increasing the service life of the base 1. It can also facilitate the cleaning and removal of dirt and debris between the base 1 and the bottom of the aquaculture pond during subsequent cleaning. The rubber suction cup 7 allows the base 1 to be firmly attached to the bottom of the aquaculture pond under the action of water pressure and the weight of the aeration disc itself, preventing unnecessary movement of the aeration disc during daily use.

[0041] Example 3: The base 1 is made of aluminum shell and is integrally molded. Three layers of anti-corrosion coating are provided on the outer surface of the base 1. At the same time, the bottom of the base 1 is provided with foot support 6, and the bottom of the foot support 6 is provided with rubber suction cup 7. After oxidation, the surface of the aluminum base 1 will form a dense protective layer of aluminum oxide. Combined with the anti-corrosion coating, it can improve the corrosion resistance of the base 1 when facing the complex environment of the aquaculture pond. At the same time, the foot support 6 raises the base 1, avoiding direct contact between the base 1 and the bottom of the aquaculture pond. This avoids friction between the base 1 and the bottom of the aquaculture pond when the base 1 is moved, thus extending the service life of the base 1. It also makes it easier to clean and remove dirt and debris between the base 1 and the bottom of the aquaculture pond during subsequent cleaning. The rubber suction cup 7 allows the base 1 to be firmly attached to the bottom of the aquaculture pond under the action of water pressure and the weight of the aeration disc itself, preventing unnecessary movement of the aeration disc during daily use.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model.
