[0028] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the information disclosed herein. This disclosure can also be implemented or applied through other different specific embodiments, and various details in this disclosure can be modified or changed according to different viewpoints and application modules without departing from the spirit of this disclosure. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this disclosure can be combined with each other.

[0029] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings, so that those skilled in the art to which this disclosure pertains can readily implement it. This disclosure may be embodied in many different forms and is not limited to the embodiments described herein.

[0030] In this disclosure, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic represented in connection with that embodiment or example is included in at least one embodiment or example of this disclosure. Furthermore, the specific features, structures, materials, or characteristics represented may be combined in any suitable manner in any one or a group of embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples represented in this disclosure, as well as the features of those different embodiments or examples.

[0031] Furthermore, the terms "first" and "second" are used for illustrative purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the representation of this disclosure, "a set" means two or more, unless otherwise explicitly specified.

[0032] For the purpose of clarity, devices unrelated to the description are omitted, and the same or similar components throughout the specification are given the same reference numerals.

[0033] Throughout this specification, when it is said that a device is "connected" to another device, this includes not only "direct connection" but also "indirect connection" by placing other components in between. Furthermore, when it is said that a device "comprises" a certain constituent element, unless otherwise stated otherwise, this does not exclude other constituent elements, but rather implies that other constituent elements may be included.

[0034] While the terms first, second, etc., are used in some examples herein to refer to various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from another. For example, first interface and second interface, etc., are used. Furthermore, as used herein, the singular forms “a,” “an,” and “the” are intended to also include the plural forms unless the context indicates otherwise. It should be further understood that the terms “comprising,” “including,” indicate the presence of the stated feature, step, operation, element, module, item, kind, and / or group, but do not exclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, modules, items, kinds, and / or groups. The terms “or” and “and / or” as used herein are interpreted as inclusive, or mean any one or any combination thereof. Thus, “A, B, or C” or “A, B, and / or C” means “any one of: A; B; C; A and B; A and C; B and C; A, B, and C.” Exceptions to this definition will only occur if the combination of elements, functions, steps, or operations is inherently mutually exclusive in some way.

[0035] The technical terms used herein are for reference only to specific embodiments and are not intended to limit the scope of this disclosure. The singular form used herein includes the plural form unless the statement explicitly indicates otherwise. The word "comprising" as used in this specification means to specify a particular characteristic, region, integer, step, operation, element, and / or component, and does not exclude the presence or addition of other characteristics, regions, integers, steps, operations, elements, and / or components.

[0036] Although not explicitly defined, all terms, including technical and scientific terms used herein, shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. Terms defined in commonly used dictionaries shall be further interpreted as having a meaning consistent with the relevant technical literature and the message of the present disclosure, and shall not be over-interpreted as having an ideal or overly formulaic meaning unless otherwise defined.

[0037] Membrane bioreactor (MBR) technology is a novel and highly efficient wastewater treatment process that combines efficient membrane separation technology with the traditional activated sludge process. The MBR achieves efficient sludge-water separation through hollow fiber membranes. Simultaneously, due to its effective retention capacity, it can retain microorganisms with long generation cycles, achieving deep wastewater purification. Furthermore, nitrifying bacteria can proliferate fully within the system, resulting in significant nitrification and enabling advanced phosphorus and nitrogen removal.

[0038] Based on the above problems, the engagement mechanism of the aeration component provided in this embodiment of the present disclosure, through the engagement connection between the engaging part and the engaging part, can both realize the disassembly and connection of the gas collecting hood and the gas storage shell, facilitating replacement and maintenance, and can also quickly install the gas collecting hood onto the gas storage shell, improving installation efficiency.

[0039] Figure 1 The diagram shown is a schematic representation of the overall structure of an embodiment of this disclosure. Figure 2 The diagram shown is a cross-sectional view of the overall structure of an embodiment of this disclosure. Figure 3 The image shown is a cross-sectional view of the overall structure of an embodiment of this disclosure from another perspective. Figure 4 The image shown is a cross-sectional view of the overall structure of an embodiment of this disclosure from another perspective. Figure 1 , 2 3 and Figure 4 In the example, the engagement structure 40 of the aeration assembly includes an air storage shell 10, at least one air outlet pipe 20, at least one air collection hood 30, and at least one engagement structure 40. The air storage shell 10 has an aeration chamber 101 with a bottom opening, and at least one air outlet 102 is formed at the top for communication with the aeration chamber 101. One end of the air outlet pipe 20 is connected to the inner top wall of the air storage shell 10 and communicates with the air outlet 102, and the other end points to the opening and forms an air inlet 201. The air collection hood 30 is disposed on the inner wall of the air storage shell 10, and the air collection hood 301 is sleeved outside the air outlet pipe 20 with a gap between it and the inner top wall of the air storage shell 10. There is a gap between the air inlet 201 and the inner bottom wall of the air collection hood 30 so that the aeration chamber 101 and the air outlet 102 are connected. The engaging structure 40 includes a engaging portion 41 extending in a vertical direction and an engaging portion 42 engaging with the engaging portion 41; one of the engaging portion 41 and the engaging portion 42 is provided on the gas collecting hood 30, and the other is provided on the inner wall of the gas storage shell 10.

[0040] The advantage of the above configuration is that, by engaging the snap-fit ​​part 41 with the snap-fit ​​part 42, the gas collecting cover 30 and the gas storage shell 10 can be detached and connected, facilitating replacement and maintenance. It also allows for quick installation of the gas collecting cover 30 onto the gas storage shell 10, improving installation efficiency.

[0041] Combination Figure 4This example illustrates the working principle of the pulse aeration assembly. Gas is introduced into the aeration chamber 101. As the gas enters and rises within the aeration chamber 101, it forces liquid out from the bottom of the gas storage shell 10, lowering the water level in the aeration chamber 101. Since the gas collection hood 30 is connected to the aeration chamber 101 through the gas collection port 301, the water level also decreases until it drops to expose the air inlet at the bottom of the gas collection hood 30. The gas can then enter the gas collection hood 30 through the gas collection port 301 and the air inlet 201, and from the air inlet 201 into the air outlet pipe 20 for discharge at the air outlet 102, thus being diverted and output to form aeration. After aeration is formed, the wastewater in the aeration chamber 101 rises and refills the aeration chamber 101. Subsequently, by continuously filling the gas collection hood 30 with air, the pulse aeration assembly will continuously repeat the above aeration process. Therefore, the aeration assembly will form an intermittent aeration.

[0042] For example, multiple air outlet pipes 20, air collection hoods 30, and locking structures 40 are implemented. The multiple air outlet pipes 20 are arranged at intervals along the extending direction of the air storage shell 10. The multiple air outlet pipes 20 have the same inner diameter, that is, the multiple air inlets 201 have the same diameter.

[0043] exist Figure 4 In the example, the air outlet pipe 20 is coaxially arranged with the air outlet 102; the air outlet pipe 20 is also coaxially arranged with the gas collection hood 30. Further exemplarily, the air outlet pipe 20 is a pipe with a straight central axis coaxial with the air outlet 102, and the gas collection hood 30 is a hood extending in a straight line coaxially with the air outlet pipe 20 (i.e., their central axes coincide). Further exemplarily, the gas collection hood 30 and the air outlet pipe 20 can be coaxially arranged along one extension direction of the gas storage shell 10. The coaxial arrangement of the air outlet pipe 20 and the gas collection hood 30 is more conducive to breaking the balance at the moment of pulse aeration, making pulse aeration easier and more uniform, and unaffected by the environment. In other embodiments, the air outlet pipe 20 and the gas collection hood 30 are configured eccentrically.

[0044] exist Figure 4 In the example, the bottom end of the gas collection hood is provided with a discharge hole 302. The discharge hole 302 is used to discharge the sludge sediment in the aeration chamber 301 of the gas collection hood 30 from the discharge hole 302 into the aeration chamber 301.

[0045] exist Figure 2In the example, the outer wall of the gas collection hood 30 is provided with at least a pair of mounting feet 31; the engaging structure 40 is implemented as a pair; the engaging portion 41 is provided on the inner wall of the gas storage shell 10; and the engaging portion 42 is provided on the mounting feet 31. Exemplarily, the engaging portion 41 is implemented as a slot, and the engaging portion 42 is implemented as a block that engages with the shape of the slot, so as to define the position of the gas collection hood 30 in the horizontal direction.

[0046] In another embodiment, the mounting feet are implemented as three or four. The three or four mounting feet are spaced apart along the circumference of the gas collecting hood on the outer wall of the hood. That is, the number of mounting feet can also be more than two or more pairs, and is not limited to this embodiment.

[0047] In another embodiment, the snap-fit ​​portion is provided on the mounting foot; the snap-fit ​​portion is provided on the inner wall of the gas storage shell. In another embodiment, the pair of mounting feet may be arranged back-to-back to connect to relative positions on the inner wall of the gas storage shell.

[0048] Figure 5 The following is an embodiment of this disclosure. Figure 3 Enlarged view of A. The cross-sectional shape of the latching portion 41 and the inserting portion 42 is T-shaped. Figure 6 The diagram shown is a structural schematic of another embodiment of the engaging structure in this disclosure. Figure 6 In the example, the cross-sectional shape of the latching portion 41A and the inserting portion 42A is implemented as a broken line shape. Figure 7 The diagram shown is a structural schematic of another embodiment of the engaging structure in this disclosure. Figure 7 In the example, the cross-sectional shapes of the latching portion 41B and the inserting portion 42B are implemented as curved. Those skilled in the art will understand that... Figure 3 , 6 In both examples 7 and 8, the fixing effect between the gas collecting hood 30 and the gas storage shell 10 is improved by increasing the contact area between the snap-fit ​​portion and the snap-fit ​​portion. In other embodiments, the cross-sectional shape of the snap-fit ​​portion and the snap-fit ​​portion is implemented as a polygonal shape plus a curved shape.

[0049] exist Figure 2 In the example, the snap-fit ​​portion 41 and the snap-fit ​​portion 42 are made of a thermoplastic material. The portion of the snap-fit ​​portion 42 protruding from the snap-fit ​​portion 41 forms a fixing point for thermoplastic welding, thereby fixing the gas collecting hood 30 to the inner wall of the gas storage shell 10 by thermoplastic welding. Those skilled in the art will understand that the gas collecting hood 30 can be fixed by thermoplastic welding. The advantage is that the gas collecting hood 30 does not need to be fixed with metal screws, avoiding the metal corrosion problem of the pulse aeration assembly in various wastewater applications, and providing a strong and secure fit, greatly improving the lifespan of the pulse aeration assembly.

[0050] For example, the engaging structure 40 further includes a limiting member 43; the limiting member 43 is movably coupled to the gas storage shell 10 or the gas collection hood 30 along a direction perpendicular to the extending direction of the engaging portion 41, so as to restrict the engaging portion 41 from disengaging from the engaging portion 42 after the engaging portion 41 engages with the engaging portion 42.

[0051] Figure 8 The diagram shown is a schematic representation of the overall structure of the limiting member and the engaging structure in an embodiment of this disclosure. Figure 8 In the example, the engaging structure 40 further includes a limiting member 43. The limiting member 43 is implemented as a bolt. The limiting member 43 is screwed to the gas storage shell 10. When the engaging portion 42 engages with the engaging portion 41, the bolt moves to abut against the engaging portion 42. It can be understood that the limiting member 43, by applying a horizontal clamping force to the engaging portion 42, restricts the vertical displacement of the gas collecting hood 30, thereby preventing the engaging portion 42 on the gas collecting hood 30 from disengaging from the engaging portion 41 due to vibration during pulse aeration. This avoids pulse aeration failure caused by the detachment of the gas collecting hood 30, thus improving aeration efficiency. Exemplarily, the limiting member 43 is made of plastic or other corrosion-resistant materials.

[0052] In another embodiment, the wall surface of the insert portion facing the limiting member is formed with a clearance hole for the limiting member to be inserted with a clearance fit. Inserting one end of the limiting member into the clearance hole can further improve the limiting effect of the limiting member on the gas collection hood.

[0053] Figure 9 The diagram shown is a schematic representation of the overall structure of the limiting member and the engaging structure in another embodiment of this disclosure. Figure 9In the example, the engaging structure 40 further includes a limiting member 43A. The limiting member 43A is slidably engaged with the vertical sidewall of the engaging portion 41 along a direction perpendicular to the extension of the engaging portion 41. An elastic member 44 is provided between the end of the limiting member 43A facing away from the engaging portion 42 and the gas storage shell 10; the end face of the limiting member 43A facing the engaging portion is an inclined surface, the high end of the inclined surface is closer to the engaging portion 42 in the horizontal direction, and the inclined surface portion is exposed outside the engaging portion 41. Therefore, those skilled in the art will understand that one end of the top wall of the engaging portion 42 abuts against the inclined surface when inserted into the engaging portion 41, squeezing the limiting member 43A and causing it to compress the elastic member 44. After the limiting member 43A is completely concealed from the engaging portion 41, the engaging portion 42 can completely pass upward over the limiting member 43A. At this time, under the elastic reaction of the elastic member 44, the limiting member 43A moves to the path of the engaging portion 42 moving downward, thereby preventing the engaging portion 42 from disengaging from the engaging portion 41. For example, the limiting member 43A is made of plastic or other corrosion-resistant materials.

[0054] Another embodiment of this disclosure provides an aeration assembly, including an engagement structure for the aeration assembly. Another embodiment of this disclosure provides a membrane module, including the aeration assembly.

[0055] The engagement structure of the aeration component provided in this embodiment is also applicable to the gas collection hood in a pulse membrane module and its working method, which is patented under patent number CN2021100006667.

[0056] In summary, this disclosure provides an engagement structure for an aeration assembly, as well as the aeration assembly and membrane module thereof. The engagement mechanism of the aeration assembly includes an air storage shell having an aeration chamber with a bottom opening and at least one air outlet formed at the top for communication with the aeration chamber; at least one air outlet pipe, one end connected to the inner top wall of the air storage shell and communicating with the air outlet, and the other end pointing towards the opening and forming an air inlet; at least one air collection hood disposed on the inner wall of the air storage shell, with the air collection port spaced from the inner top wall of the air storage shell and fitted outside the air outlet pipe, and a gap between the air inlet and the inner bottom wall of the air collection hood to allow communication between the aeration chamber and the air outlet; at least one engagement structure including a vertically extending engagement portion and a snap-fit ​​portion engaging with the engagement portion; one of the engagement portion and the snap-fit ​​portion is disposed on the air collection hood, and the other is disposed on the inner wall of the air storage shell. The aeration assembly includes the engagement structure of the aeration assembly. The membrane module includes the aeration assembly. The advantage of this design is that the snap-fit ​​connection between the snap-fit ​​part and the snap-fit ​​part allows for easy disassembly and reassembly of the gas collection hood and the gas storage shell, facilitating replacement and maintenance. It also allows for quick installation of the gas collection hood onto the gas storage shell, improving installation efficiency.

[0057] The above embodiments are merely illustrative of the principles and effects of this disclosure and are not intended to limit this disclosure. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this disclosure. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this disclosure should still be covered by the protection scope of this disclosure.
