[0002] Microporous aerator is an essential equipment for aeration and oxygenation. In the field of sewage treatment, microporous aerator is increasingly widely used due to its advantages such as small aeration bubble diameter, uniform bubble diffusion, and large gas-liquid interface area.

[0003] During the installation of the aeration membrane, the aeration membrane needs to be set on the mounting plate in advance. The existing aeration membrane installation methods are roughly divided into two types. The first is to install it directly through mounting components (such as screws), etc. This installation method can easily cause damage to the aeration membrane. The second is to fix it on the mounting plate through other components for installation. This installation method requires the aeration membrane to be fixed in advance. Before the aeration membrane is installed, the aeration membrane is likely to shift, resulting in an unstable installation position of the aeration membrane. Utility Model Content

[0042] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0043] Figure 1-Figure 3 FIG. 1 shows a structural diagram of an aeration membrane 130 installation structure 100 according to an embodiment of the present application. Figure 1-Figure 3 As shown, the mounting structure 100 may include:

[0044] Aeration plate 110;

[0045] The boss 120 is provided on the aeration plate 110 and has aeration holes 111;

[0046] An aeration membrane 130 , the aeration membrane 130 covers the aeration plate 110 , and the boss 120 is wrapped in the aeration membrane 130 ;

[0047] The pressing frame 140 is detachably mounted on the aeration plate 110 . When the pressing frame 140 is connected to the aeration plate 110 , the aeration membrane 130 is located between the pressing frame 140 and the aeration plate 110 .

[0048] In this embodiment, during installation, the aeration plate 110 is connected to the air distribution pipe 150, so that the aeration holes 111 on the boss 120 are connected to the air distribution pipe 150, and a sealing ring is provided between the air distribution pipe 150 and the aeration plate 110. The aeration membrane 130 is installed on the boss 120 so that the boss 120 is wrapped in the aeration membrane 130. The boss 120 is wrapped inside by the aeration membrane 130, ensuring that all the gas transported in the air distribution pipe 150 is aerated and then output through the aeration membrane 130. At the same time, the boss 120 pre-positions the aeration membrane 130 to facilitate the installation of the pressing frame 140. After the aeration membrane 130 is sleeved on the boss 120, the pressing frame 140 is fixed to the aeration plate 110 through the connecting piece. The pressing frame 140 fixes the aeration membrane 130 so that the aeration membrane 130 is fixed to the pressing frame 140.

[0049] Furthermore, the connecting member is a bolt, and can also be set in the form of a bolt and a nut. When the connecting member is a bolt, the bolt is directly threadedly connected to the pressure frame 140. At this time, a thread is provided on the pressure frame 140. The connecting member in this solution is in the form of a bolt. The bolt passes through the aeration plate 110 and is threadedly connected to the pressure frame 140 to ensure the smoothness of the surface of the pressure frame 140 and increase the aesthetics.

[0050] By providing a boss 120 on the aeration plate 110, when the aeration membrane 130 is installed, the aeration membrane 130 wraps the boss 120, thereby ensuring the sealing when the aeration membrane 130 is connected to the aeration plate 110. The aeration membrane 130 is positioned before installing the pressing frame 140 to avoid the aeration membrane 130 from being offset, which affects the airtightness between the aeration membrane 130 and the aeration plate 110. The pressing frame 140 is detachably connected to the aeration plate 110, which facilitates the fixing of the aeration membrane 130 on the boss 120, and avoids damage to the aeration membrane 130 when directly fixing the aeration membrane 130 on the aeration plate 110, which affects the secondary use of the aeration membrane 130.

[0051] like Figure 2 As shown, in one embodiment,

[0052] The aeration plate 110 is disposed on the air distribution pipe 150 , and the aeration holes 111 are connected to the air distribution pipe 150 .

[0053] In this embodiment, the aeration plate 110 and the air distribution pipe 150 are installed by screws, the aeration hole 111 is connected to the air distribution pipe 150, and a sealing ring is provided at the connection between the aeration plate 110 and the air distribution pipe 150 to prevent air leakage at the connection between the aeration plate 110 and the air distribution pipe 150.

[0054] like Figure 2-Figure 3 As shown, in one embodiment,

[0055] A first protrusion 121 is provided around the side of the boss 120 . When the boss 120 is wrapped inside the aeration membrane 130 , the first protrusion 121 is also located inside the aeration membrane 130 .

[0056] In this embodiment, through the arrangement of the first protrusion 121 , when the aeration membrane 130 is sleeved on the boss 120 , the first protrusion 121 is located inside the aeration membrane 130 ;

[0057] Further,

[0058] The aeration membrane 130 has a groove 131 that is adapted to the shape of the boss 120, and the side of the aeration membrane 130 has a depression 132 that is adapted to the first protrusion 121. The setting of the first protrusion 121 ensures the stability of the connection between the aeration membrane 130 and the boss 120. While performing the preliminary positioning of the aeration membrane 130, the stability of the connection between the aeration membrane 130 and the aeration plate 110 is ensured.

[0059] like Figure 3 As shown, in one embodiment,

[0060] The side cross-section of the aeration membrane 130 is arranged in a “C” shape.

[0061] In this embodiment, the side cross-section of the aeration membrane 130 is C-shaped, that is, the recess 132 in the aeration membrane 130 is C-shaped. When the aeration membrane 130 is installed on the aeration plate 110, the boss 120 is located in the groove 131, and the first protrusion 121 is located in the recess 132, so that the aeration membrane 130 is fixed on the protrusion.

[0062] like Figure 2-Figure 3 As shown, in one embodiment,

[0063] A second protrusion 141 is provided on the inner wall of the pressing frame 140 . When the pressing frame 140 is disposed on the aeration plate 110 , the second protrusion 141 is in contact with the aeration membrane 130 .

[0064] In this embodiment, when the pressure frame 140 is installed on the aeration plate 110, the side of the aeration membrane 130 is in contact with the inner wall of the pressure frame 140. The second protrusion 141 is provided on the aeration membrane 130 to exert pressure on the aeration membrane 130 so that the aeration membrane 130 is in contact with the aeration plate 110.

[0065] Further,

[0066] The size of the aeration membrane 130 is larger than the size of the second protrusion 141 and smaller than the size of the pressure frame 140;

[0067] The size of the aeration membrane 130 is smaller than that of the pressure frame 140, which makes it easier for the pressure frame 140 to be mounted on the aeration membrane 130. When the pressure frame 140 is installed on the aeration plate 110, since the size of the aeration membrane 130 is larger than the size of the second protrusion 141, the second protrusion 141 can fix the aeration membrane 130 on the aeration plate 110, and cooperate with the first protrusion 121 to fix the aeration membrane 130 to prevent the aeration membrane 130 from falling off.

[0068] like Figure 1-Figure 2 As shown, in one embodiment,

[0069] The size of the frame 140 is the same as that of the aeration plate 110 , and the frame 140 and the aeration plate 110 are detachably mounted via connectors.

[0070] In this embodiment, the outer ring size of the frame 140 is the same as the size and shape of the aeration plate 110. When the frame 140 is installed on the aeration plate 110, the aesthetics of the surface of the frame 140 and the aeration plate 110 are ensured.

[0071] like Figure 2-Figure 3 As shown, in one embodiment,

[0072] The aeration membrane 130 has a plurality of pores, and the pores are all connected to the groove 131 .

[0073] In this embodiment,

[0074] When the aeration membrane 130 is connected to the boss 120, the gas in the air distribution pipe 150 enters the groove 131 through the aeration holes 111 on the boss 120 and is output through a plurality of air holes. The second protrusion 141 on the pressure frame 140 cooperates with the first protrusion 121 to ensure that the gas is located between the boss 120 and the aeration membrane 130 when it is discharged from the aeration holes 111 on the boss 120, and is discharged through the air holes on the aeration membrane 130, thereby improving the aeration efficiency and reducing the occurrence of air leakage.
