Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and in particular to an aerator. Background Technology

[0002] Aerators are the core equipment for achieving efficient aeration in wastewater treatment processes. Currently, the common types of aerators on the market include disc aerators, plate aerators, and tubular aerators. Among them, tubular aerators are widely used in industrial wastewater treatment and biological treatment tank renovation due to their advantages such as uniform air distribution, strong anti-clogging ability, and long service life.

[0003] In existing technologies, tubular aerators are susceptible to airflow friction, which increases local wear and reduces their lifespan. Furthermore, tubular aerators are typically composed of aeration pipes, lining pipes, and connectors made of polymer materials (such as EPDM and silicone rubber), with most components made of PVC or ABS. These components suffer from insufficient structural stability, are prone to creep deformation, leading to diaphragm damage and shortened service life. Summary of the Invention

[0004] The purpose of this invention is to provide an aerator.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An aerator includes an air guide, an inner liner support tube, a tail end support, a tubular diaphragm, and a single-ear stepless clamp. The air guide, tail end support, and inner liner support tube are all fixedly connected. The tubular diaphragm is sleeved on the inner liner support tube. The side wall of the air guide has several channels evenly distributed around it.

[0007] Preferably, the air guide, tail support and inner liner support tube are made of a composite material of copolymer polypropylene and glass fiber.

[0008] Preferably, the tubular diaphragm is detachably connected to the inner lining support tube by a single-ear stepless clamp.

[0009] Preferably, the channel size is 10mm × 10mm. Beneficial effects

[0010] This invention reduces air resistance, allowing the diaphragm to share the airflow friction at multiple locations, thus reducing localized wear on the diaphragm and extending the aerator's lifespan. The evenly distributed channels promote 360° uniform airflow, improving the product's dissolved oxygen efficiency, reducing energy consumption, and enhancing the product's mechanical properties, thermal stability, and corrosion resistance.

[0011] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0017] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] like Figures 1-4 As shown, an aerator includes an air guide 1, an inner liner support tube 2, a tail end support 3, a tubular diaphragm 4, and a single-ear stepless clamp; the air guide 1, the tail end support 3, and the inner liner support tube 2 are all fixedly connected by welding; the tubular diaphragm 4 is sleeved on the inner liner support tube 2, and the tubular diaphragm 4 is detachably connected to the inner liner support tube 2 by a single-ear stepless clamp; the side wall of the air guide has three channels evenly opened circumferentially.

[0022] Preferably, the air guide 1, the tail support 3, and the inner lining support tube 2 are made of a composite material of copolymer polypropylene and glass fiber, which improves the mechanical properties, thermal stability, and corrosion resistance of the product.

[0023] Preferably, the tubular diaphragm is detachably connected to the inner lining support tube by a single-ear infinite clamp.

[0024] Preferably, the channel size is 10mm × 10mm.

[0025] During use, the air guide 1 disperses the gas into tiny bubbles, significantly increasing the gas-liquid contact area and thus improving the oxygen mass transfer efficiency. The three channels 101 of the air guide 1 allow the diaphragm to bear the airflow friction at multiple locations, reducing local wear on the tubular diaphragm 4 and extending the aerator's lifespan. The evenly distributed channels 101 promote 360° uniform airflow, improving the dissolved oxygen efficiency of this product and reducing energy consumption.

[0026] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0027] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
