Description

Technical Field

[0001] This utility model relates to an aeration device for use in aquatic environments, particularly a large-sized, stable, and efficient disc aerator. Background Technology

[0002] In the field of water treatment technology, aeration equipment is needed to increase oxygen levels. For example, in aquaculture, aeration equipment is used to increase oxygen levels for aquaculture. Swimming pools also need oxygenation to improve the swimming pool's environment and performance.

[0003] Especially in wastewater treatment, aeration and oxygenation processes are required. Traditional disc aerators suffer from problems such as easy aging, poor tear resistance, and easy clogging of aeration holes, leading to rapid decline in aeration efficiency and high maintenance costs. In addition, traditional aerators have complex support structures and are inconvenient to install. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a large-size, stable, and efficient disc aerator, including...

[0005] The technical solution of this utility model specifically relates to a large-size, stable, and efficient disc aerator, comprising:

[0006] A base, wherein an air intake is provided on the base from bottom to top;

[0007] An aeration membrane is disposed above a base and is connected to the air inlet of the base.

[0008] A locking assembly is disposed on the base and the locking assembly seals and presses the aeration membrane sheet tightly against the base around its perimeter.

[0009] Aeration holes, wherein the aeration holes are disposed on the aeration membrane and are distributed concentrically along the aeration membrane; and

[0010] A one-way diaphragm is provided in the air intake channel of the air intake section, and the opening direction of the one-way diaphragm is consistent with the air intake direction.

[0011] Furthermore, the locking assembly includes:

[0012] Locking disc, which is connected to the base; and

[0013] The clamping part is located on the inner side of the locking disc, and is situated above the aeration membrane, pressing it against its circumference. The locking assembly further clamps the aeration membrane, ensuring its stable operation.

[0014] Furthermore, the connection between the locking disc and the base is at least one of magnetic, snap-fit, or threaded connection. Generally, a threaded connection is sufficient, but snap-fit ​​can also be used for locking, or a magnetic connection can be used in conjunction with a snap-fit ​​connection.

[0015] Furthermore, an elastic element is provided on the base, and an elastic positioning hole is provided on the locking assembly, with the elastic element corresponding to the elastic positioning hole. This positioning structure ensures a stable connection between the two.

[0016] Furthermore, the elastic element is inclined, and the direction of the inclination is opposite to the direction of the threaded installation of both components. This ensures the stability of their installation.

[0017] Furthermore, the aeration membrane has protruding clamping posts around its perimeter, and a clamping groove is provided on the base. The clamping posts and clamping grooves are fitted together. This ensures that the aeration membrane is firmly clamped around its perimeter, guaranteeing stable subsequent aeration.

[0018] Furthermore, the aeration holes can be any one of the following: circular, square, T-shaped, Y-shaped, X-shaped, I-shaped, or I-shaped. This paper specifically uses I-shaped holes to ensure smooth flow of bubbles when they are generated, and the I-shaped holes naturally recover their original shape when the bubbles disappear, preventing impurities from entering.

[0019] Furthermore, at least one reinforcing rib is integrally formed on the lower side of the base. The addition of the reinforcing rib facilitates the improvement of the overall structural strength of the base.

[0020] Furthermore, the reinforcing ribs are arranged radially from the center outwards, or in concentric circles, or in arcs. Generally, a radial arrangement is sufficient. The built-in high-strength engineering plastic support frame employs a radial hollow design, combining lightweight design with compressive strength.

[0021] Furthermore, the base can be shaped like a disc, square, pentagon, or triangle. Generally, a circular shape is sufficient.

[0022] Furthermore, a threaded section is provided on the lower side of the air inlet. Other gas pipes can be connected via this thread. The bottom of the aeration disc has a quick-connect interface for rapid connection to the air supply line via a sealing clamp, requiring no special tools and facilitating subsequent use.

[0023] Furthermore, the aeration membrane is integrally molded from TPU material. The surface of the aeration membrane has a plurality of variable-diameter aeration holes, such as I-shaped holes, evenly distributed to prevent clogging.

[0024] This invention provides a large-sized, stable, and efficient disc aerator. It features a simple structure, strong corrosion resistance, stable aeration efficiency, and convenient and quick installation. The overall design also includes an anti-backflow feature: a unidirectional elastic diaphragm automatically closes when the system stops, preventing sewage backflow. This ensures stable and efficient operation of the aeration disc. Attached Figure Description

The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0040] See appendix Figure 1-9As shown in this embodiment, a large-sized, stable, and efficient disc aerator includes:

[0042] Aeration membrane 3 is disposed above the base 1 and is connected to the air inlet 2 of the base 1.

[0043] Locking component 4 is mounted on base 1 and seals and presses the aeration membrane 3 to base 1 around its perimeter.

[0044] Aeration holes 5 are disposed on the aeration membrane 3, and the aeration holes 5 are distributed concentrically along the aeration membrane 3; and

[0047] Locking disc 41, locking disc 41 is connected to base 1; and

[0048] The pressing part 42 is provided inside the locking disc 41. The pressing part 42 is located on the upper side of the aeration membrane 3 and presses the aeration membrane 3 around its perimeter. At the same time, the locking assembly 4 can press the aeration membrane 3 tightly, ensuring the stable operation of the aeration membrane 3.

[0049] Furthermore, the connection between the locking disc 41 and the base 1 is at least one of magnetic attraction, snap-fit, or threaded connection. Generally, a threaded connection is sufficient, but snap-fit ​​can also be used for locking, or a magnetic connection can be used in conjunction with a snap-fit ​​connection.

[0050] Furthermore, an elastic element 6 is provided on the base 1, and an elastic positioning hole 7 is provided on the locking assembly 4, with the elastic element 6 corresponding to the elastic positioning hole 7. This positioning structure ensures the stability of the connection between the two.

[0051] Furthermore, the elastic element 6 is inclined, and the inclination direction of the elastic element 6 is opposite to the direction of the threaded installation of both components. This ensures the stability of their installation.

[0052] Furthermore, pressing posts 31 protrude around the aeration membrane 3, and pressing grooves 11 are provided on the base 1. The pressing posts 31 and pressing grooves 11 are fitted together. This ensures that the aeration membrane 3 is pressed tightly around its perimeter, ensuring stable subsequent aeration.

[0053] Furthermore, the aeration holes 5 can be any one of the following: circular, square, T-shaped, Y-shaped, X-shaped, I-shaped, or I-shaped. This paper specifically uses I-shaped holes to ensure smooth flow of bubbles when they are generated, and the I-shaped holes naturally return to their original shape when the bubbles disappear, preventing impurities from entering.

[0054] Furthermore, at least one reinforcing rib 8 is integrally provided on the lower side of the base 1. The inclusion of the reinforcing rib 8 facilitates the improvement of the overall structural strength of the base 1.

[0055] Furthermore, the reinforcing ribs 8 are arranged radially from the center outwards, or in concentric circles, or in arcs. Generally, a radial arrangement is sufficient. An internal high-strength engineering plastic support frame with a radial hollow design combines lightweight and compressive strength.

[0056] Furthermore, the base 1 can be shaped like a disc, square, pentagon, or triangle. Generally, a circular shape is sufficient.

[0057] Furthermore, a threaded section is provided on the lower side of the air inlet 2. Other gas pipes can be connected via this thread. A quick-connect interface is located at the bottom of the aeration disc, allowing for rapid connection to the air supply line via a sealing clamp, eliminating the need for special tools and facilitating subsequent use.

[0058] Furthermore, the aeration membrane 3 is integrally molded from TPU material. The surface of the aeration membrane 3 has a plurality of variable-diameter aeration holes 5, such as I-shaped holes, evenly distributed to prevent clogging. The TPU material is a hydrolysis-resistant thermoplastic polyurethane with a hardness of 80A-95A. The aeration disc diameter is 200-350mm, and the aeration membrane thickness is 0.8-2mm. The aeration holes have a diameter of 0.1-2mm and are arranged concentrically. The supporting frame and the TPU layer are combined using an in-mold injection molding process to ensure structural stability.

These aerators feature a simple structure, strong corrosion resistance, stable aeration efficiency, and are easy and quick to install. They also incorporate an anti-backflow design: a one-way elastic diaphragm automatically closes when the system stops, preventing sewage backflow. This ensures stable and efficient operation of the aeration discs.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
