Detailed Implementation

[0030] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0031] Please see Figure 1 , Figure 2 and Figure 3A ceramic aeration plate according to an embodiment of the present invention includes a ceramic plate 3 and a metal base 1. The top of the metal base 1 has an installation groove 2. The ceramic plate 3 is bonded to the inside of the installation groove 2 with a special adhesive, which is either polyurethane adhesive or epoxy resin adhesive. The metal base 1 serves as the basic load-bearing structure of the ceramic aeration plate, providing stable support and a mounting foundation. The installation groove 2 is used to position the ceramic plate 3, ensuring precise alignment with the metal base 1 and providing a sealed space for the special adhesive bonding. The ceramic plate 3 contains vertically penetrating micropores that allow airflow. The porosity of the micropores is 35-45%, and the pore size is 0.5-2 μm. The ceramic plate 3, as the core aeration element, disperses air into tiny bubbles through micropores, improving the dissolved oxygen efficiency of the water. The microporous structure can generate a large number of tiny bubbles, increasing the gas-liquid contact area and improving the oxygen transfer rate. Three sets of installation and positioning components 5 are installed on the metal base 1. The three sets of installation and positioning components 5 enhance the overall stability of the aeration plate through counterweight and mechanical positioning, preventing displacement due to buoyancy or water flow impact during aeration. Above each of the three sets of installation and positioning components 5, there are fastening components 6 for limiting and reinforcing the ceramic plate 3. The fastening components 6 apply pressure from the top of the ceramic plate and are fixed with special adhesive to prevent the ceramic plate 3 from loosening due to gas impact or thermal expansion and contraction.

[0032] Please see Figure 2 An air inlet pipe 4 is installed on one side of the metal base 1. One end of the air inlet pipe 4 is connected to the cavity inside the metal base 1, and the other end of the air inlet pipe 4 is connected to an external air pump. The compressed air generated by the air pump enters the cavity of the metal base 1 through the air inlet pipe 4 to form a stable air pressure, which drives the gas to aerate through the micropores of the ceramic plate 3.

[0033] Please see Figure 1 Three sets of installation and positioning components 5 are respectively set at the front end, middle end and rear end of the metal base 1; each set of installation and positioning components 5 includes two positioning seats 51 fixed on the two symmetrical sides of the metal base 1. The positioning seats 51 are fixed on both sides of the metal base to provide an installation platform for the counterweight and fastening components 6. The positioning seats 51 are provided with a placement cavity 52 for placing the counterweight. The placement cavity 52 accommodates the counterweight (such as a concrete block or a metal block) to increase the overall weight and offset the buoyancy during aeration. The bottom of the placement cavity 52 is equipped with a plug rod 53, which is inserted into the preset hole of the counterweight to prevent the counterweight from sliding or falling off.

[0034] Please see Figure 1 and Figure 3The fastening assembly 6 includes a mounting base 61 fixedly installed on the top of the positioning base 51. A mounting bracket 63 is connected to the top of the mounting base 61 via a rotating shaft 62. This design allows the mounting bracket 63 to be flipped open and closed, facilitating the installation, maintenance, and replacement of the ceramic plate 3. The mounting bracket 63 is "U"-shaped, and a threaded sleeve 64 is fixedly installed at the top center of the mounting bracket 63. A screw 65 is internally threaded onto the threaded sleeve 64. A lifting plate 66 is movably connected to the bottom end of the screw 65. Limiting seats 67 are installed on both sides of the bottom end of the lifting plate 66. The rotational motion is converted into linear lifting of the screw 65 through threaded transmission, driving the lifting plate 66 to press down. The lifting plate 66 moves down under the push of the screw 65. The limiting seats 67 directly contact the surface of the ceramic plate 3, providing uniform pressure. The limiting seats 67 are made of flexible material (such as silicone) to avoid damaging the ceramic plate.

[0035] Please see Figure 3 Two guide rods 68 are fixedly installed at the top of the lifting plate 66. Both guide rods 68 are slidably connected to the mounting frame 63. The guide rods 68 ensure that the lifting plate is lifted vertically and avoids deviation. A handwheel 69 is fixedly installed at the top of the screw 65. The handwheel 69 is a manually operated component, which facilitates quick adjustment of pressure and disassembly / reassembly operations.

[0036] The working principle of a ceramic aeration plate is as follows: The ceramic plate 3 is bonded to the mounting groove 2 of the metal base 1 with special adhesive. The mounting bracket 63 of the fastening component 6 is closed. The handwheel 69 is rotated to make the limiting seat 67 press the edge of the ceramic plate 3. A counterweight is placed in the placement cavity 52 of the positioning seat 51 and fixed by the insertion rod 53. The weight of the counterweight and the mechanical limiting of the insertion rod 53 are used to stably fix the aeration plate at the bottom of the water or a designated position. An external air pump inputs compressed air into the internal cavity of the metal base 1 through the air inlet pipe 4. The gas forms a stable air pressure in the cavity and acts evenly on the bottom of the ceramic plate 3. Under the drive of air pressure, the gas escapes through the vertical micropores of the ceramic plate 3 and disperses into tiny bubbles that enter the water body to complete the aeration and oxygenation. The metal base 1 provides structural support, the counterweight counteracts buoyancy through the mounting positioning component 5, and the fastening component 6 presses the ceramic plate 3 from the top. The three work together to ensure that the aeration plate works stably underwater and avoids displacement or leakage.
