Description

Technical Field

[0001] This utility model relates to a microporous aerator, and more particularly to a slatted flexible high-efficiency aerator. Background Technology

[0002] As the core equipment for aeration and oxygenation in wastewater treatment, the performance of aerators directly affects wastewater treatment efficiency and energy consumption. Traditional aeration devices mainly suffer from the following technical defects: In terms of structural design, tubular and disc aerators adopt an integrated structure, requiring individual connection of each aerator to the bottom pipe during installation. This not only results in a long construction period but also necessitates complete disassembly and replacement for later maintenance, leading to a significant waste of manpower and resources. Regarding the microporous structure, the micropores of traditional aerators are prone to scaling and blockage due to impurities in the wastewater, causing a significant decrease in aeration efficiency over time and requiring frequent backwashing maintenance. In terms of mechanical connection, existing aeration devices mostly use rigid fixing to fix the aeration membrane to the supporting structure. When high-pressure gas is introduced, stress concentration easily occurs at the connection between the membrane and the supporting structure, leading to membrane rupture or detachment from the supporting structure after long-term use. In terms of maintenance costs, due to the integrated design, when a localized damage occurs, the entire aeration unit often needs to be replaced, greatly increasing maintenance costs.

[0003] While some improvements have emerged in existing technologies, such as the use of flexible aeration membranes or membrane bag structures, these solutions still have significant shortcomings. For example, some solutions employ a single-layer membrane design, which, although improving scaling through ultra-fine pore structures, makes the membrane prone to detaching from the support structure under high-pressure conditions. Other solutions, while simplifying the installation process, still rely on mechanical fixing, failing to effectively distribute stress. More importantly, none of these solutions address the issue of requiring complete replacement for localized damage. Utility Model Content

Furthermore, the aerator has a novel structural design, strong stability, long service life, and simple maintenance, which can reduce the maintenance cost of partial damage and extend the overall service life.

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0046] 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.

[0047] In some of its embodiments, such as Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, this application proposes a slatted flexible high-efficiency aerator for wastewater aeration treatment, which mainly includes an air inlet frame 100 and a plate-shaped microporous aeration unit embedded in the air inlet frame 100. The plate-shaped microporous aeration unit has a modular structure design, which consists of a support plate 200 and a microporous cylindrical membrane 300 sleeved on the support plate 200 and closed at both ends. An air inlet 114 on the air inlet frame 100 and an air inlet hole on the upper part of the microporous cylindrical membrane 300 are opened at the middle of the bottom.

[0048] The support plate 200 refers to a plate-like structure that provides rigid support, and can be made of metal or plastic. It is used to maintain the overall shape of the aeration unit and distribute airflow pressure. The microporous membrane 300 refers to a flexible membrane structure wrapped around the support plate 200, and can be made of TPU or silicone. It forms a wrap-around seal by closing both ends to prevent airflow from directly impacting the edge joints. The air inlet is a gas channel located in the middle of the bottom of the support plate 200. It can be a circular hole structure with a diameter larger than that of the air inlet 114, which facilitates the uniform introduction of gas delivered by the frame 100 into the internal cavity of the membrane.

[0049] In use, the intake frame 100 serves as the basic support structure. When gas enters through the intake port 114 on the intake frame 100, it is introduced into the internal cavity of the microporous membrane 300 through the intake hole at the bottom of the support plate 200. The support plate 200 maintains the planar shape of the microporous membrane 300, and the microporous membrane 300 expands under air pressure. The evenly distributed micropores on its surface cause the gas to be released uniformly in the form of tiny bubbles. Because the microporous membrane 300 is closed at both ends and completely wraps around the support plate 200, the airflow pressure is evenly distributed across the entire membrane surface, avoiding the stress concentration problem at the edge connection of traditional single-layer membranes.

[0050] This application's solution utilizes a modular, detachable plate-shaped microporous aeration unit in conjunction with a slotted air intake frame 100. This allows for individual replacement of the aeration membrane in case of localized damage. Simultaneously, the continuous connection structure of the buffer membrane 300 and the support plate 200 disperses stress. This design offers advantages such as a large horizontal unfolding area per unit, high aeration volume, and high oxygen utilization efficiency. Furthermore, it can be installed close to the bottom of the pool, maximizing the utilization of the pool depth and effectively increasing the wastewater treatment capacity per unit area. Moreover, its novel structural design ensures high stability, long service life, and easy maintenance, reducing maintenance costs for localized damage and extending the overall service life.

[0051] In some of these embodiments, such as Figure 6 , Figure 7 and Figure 8 As shown, this application further proposes an air intake frame 100 including a square frame 110. The square frame 110 is a rectangular frame structure, which refers to a rectangular support structure made of metal or engineering plastic. Specifically, it can be realized by welding or injection molding of aluminum alloy profiles, and is used to provide basic support and gas passage for the aeration unit. An air inlet 114 is opened on the plate at the left end of the square frame 110. The air inlet 114 is a vent hole opened along the left end of the square frame 110. The hole diameter matches the air inlet requirements of the aeration unit, and is used to realize the delivery of gas into the aeration unit. As needed, a check valve can be installed at the air inlet 114 to prevent backflow of gas in the aeration chamber and prevent sewage from entering the microporous membrane 300 through the ultrafine pores 301 on the surface of the microporous membrane 300 under water pressure.

[0052] The square frame 110 has baffles 111 on its front and rear sides, and folded edges 112 on its left and right sides that bend inward to form first slots 113 for securing the plate-shaped microporous aeration unit. The baffles 111 are flat plate structures perpendicular to the length of the square frame 110, used to limit the displacement of the aeration unit in the front-to-back direction. The folded edges 112 are protruding structures formed by bending the left and right edges of the square frame 110 inward at a 90° angle, used to form the first slots 113 that provide guidance. The square frame 110, with its rectangular frame structure, is longitudinally limited by the front and rear baffles 111, and laterally and vertically limited by the left and right folded edges 112 and the first slots 113, thus constructing a three-dimensional constrained space.

[0053] When the two ends of the plate-shaped microporous aeration unit are bent downwards and inserted into the first slot 113, the baffle 111 can prevent it from wobbling back and forth. The U-shaped first slot 113 formed by the folded edge 112 is used to clamp and fix the left and right ends of the aeration unit. During assembly, it is only necessary to bend the two ends of the aeration unit downwards and insert them into the first slot 113 to complete the positioning, without the need for additional fasteners. During disassembly, a flathead screwdriver can be used to pry up the middle of the plate-shaped microporous aeration unit to form a centrally protruding arched structure, thereby removing the plate-shaped microporous aeration unit for replacement and maintenance of the microporous membrane 300.

[0054] Furthermore, to improve the service life of the microporous membrane 300, this application proposes to install buffer diaphragms at the connection points between the front and rear side baffles 111 or the left and right end flanges 112 of the air intake frame 110 and the microporous membrane 300. The buffer diaphragm is an elastic material that is the same as or different from the material of the microporous membrane 300, such as PVC, EPDM, or silicone, which absorbs vibrational energy between the frame 110 and the diaphragm 300 through elastic deformation.

[0055] In some of these embodiments, such as Figure 5 , Figure 6 and Figure 8 As shown, this application further proposes to open first mounting holes 115 at the four corners of the square frame 110 corresponding to the air inlet 114, and connect the corresponding support plate 200 through first fasteners 140; and to open second mounting holes 116 at the middle and right ends of the square frame 110 corresponding to the air inlet 114, and connect the corresponding support plate 200 through second fasteners 150. The first locking assembly 140 and the second locking assembly 150 adopt conventional bolts, nuts or rivets, and are used to lock the left end of the support plate 200 to the left end of the square frame 100.

[0056] In some of these embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this application further proposes that the air intake frame 100 includes an air intake pipe assembly 120 disposed on the back of the square frame 110. The air intake pipe assembly 120 refers to the delivery component integrated on the back of the frame, which can be implemented by welding or bolt connection. Its function is to construct an independent air supply module to simplify the pipeline layout.

[0057] Specifically, the air inlet pipe assembly 120 consists of an air inlet pipe body 121 and an aeration connector 122 located at one end of the air inlet pipe body 121, with the other end of the air inlet pipe body 121 connected to the air inlet 114 to form an air supply path. The aeration connector 122 connected to the air inlet pipe body 121 is a standardized interface component and can be implemented using a flange or clamp connection structure. If necessary, a check valve can be installed on the air inlet pipe body 121 to prevent backflow of gas in the aeration chamber.

[0058] Furthermore, in some of these embodiments, such as Figure 1 , Figure 2 and Figure 7 As shown, this application further proposes that the air intake frame 100 also includes a mounting bracket 130. The mounting bracket 130 is a support structure used to connect the aeration frame 110 to the bottom of the aeration tank. Specifically, the connecting plate can be fixed to the back of the square frame 110 by welding or bolting to achieve stability of load transmission. If necessary, reinforcing ribs can be welded to the back of the square frame 110 to improve the overall structural stability of the square frame 110.

[0059] The mounting bracket 130 consists of a connecting plate 131 and L-shaped ear plates 132 located at both ends of the connecting plate 131. The connecting plate 131 is fixedly mounted on both sides of the back of the square frame 110. The L-shaped ear plates 132 are fixedly installed at the bottom of the aeration tank using height-adjustable fasteners. The L-shaped ear plates 132 refer to metal plates with a right-angle bend structure, and their bending angle can be designed to be 90 degrees to form a surface opposite to the bottom of the tank. The height-adjustable fasteners refer to conventionally known fasteners with threaded rods and lock nuts. By rotating the lock nut, the bolt extension length is changed, achieving continuous adjustment of the installation height.

[0060] In some of these embodiments, such as Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown, this application further proposes that the support plate 200 is a rectangular plate structure made of metal or plastic, such as aluminum alloy, stainless steel or PVC. The support plate 200 has a first vent hole 201 and a first countersunk hole 202 in the middle, and second countersunk holes 203 at both ends. The first vent hole 201 is arranged corresponding to the air inlet 114 and its diameter is larger than the diameter of the air inlet 114. There are four first countersunk holes 202 located at the four corners of the first vent hole 201. There are two sets of second countersunk holes 203 located to the right of the first vent hole. Each set of second countersunk holes 203 consists of multiple holes, arranged at intervals.

[0061] The diameter of the first vent 201 is larger than that of the inlet 114 because the difference in vent size creates a gas diffusion space. For example, when the diameter of the inlet 114 is 20mm, the first vent 201 can be 25mm, which reduces airflow impact by increasing the flow cross-section. The countersunk hole structure of the first countersunk hole 202 and the second countersunk hole 203 allows the bolt head to be embedded inside the support plate 200, keeping the connection surface flat and reducing frictional damage to the diaphragm 300.

[0062] Furthermore, it is worth noting that, such as Figure 7 and Figure 10 As shown, this application further proposes that a sealing gasket 204 be provided at the bottom of the left end of the support plate 200 corresponding to the position of the first vent 201. The sealing gasket 204 is arranged through the second vent 303 at the bottom of the microporous membrane 300 and is sealed to the air inlet 114 on the square frame 110. The sealing gasket 204 is an elastic sealing element covering the connection between the support plate 200 and the air inlet 114. Specifically, it can be made of rubber or silicone, and its function is to eliminate assembly gaps through physical filling.

[0063] In some of these embodiments, such as Figure 1 , Figure 5 , Figure 7 , Figure 8 , Figure 11 and Figure 12 As shown, this application further proposes that the microporous membrane 300 is made of TPU, TPEE, TPAE, TPV, or TPR material, with TPU material being preferred. The microporous membrane 300 has uniformly distributed ultrafine pores 301, which are I-shaped or needle-shaped micropores with a diameter of approximately 0.1-3 mm. During aeration, the gas pressure causes the micropores 301 to expand and release bubbles; after aeration stops, the membrane elastically contracts, causing the micropores 301 to automatically close, effectively preventing sludge backflow and achieving a self-cleaning function.

[0064] The sealing ends 302 of the microporous membrane 300 are sealed by high-frequency welding or folding and pressing. For example, the material is melted and bonded by high-frequency welding, or the extended portions of the microporous membrane 300 are folded to the bottom of the support plate 200 and then pressed into the first slot 113. The locking force of the support plate 200 on the square frame 110 is used to press the ends of the microporous membrane 300, thereby achieving a seal on the membrane ends.

[0065] The microporous membrane 300 has a second vent 303 and a first perforation 304 at the bottom of its left end, and two sets of second perforations 305 at the middle and right ends respectively. The second vent 303 is arranged corresponding to the air inlet 114, and its diameter is larger than that of the air inlet 114; there are four first perforations 304, located at the four corners of the second vent 303, which are respectively arranged corresponding to the four first mounting holes 114 on the square frame 110; there are two sets of second perforations 305, located at the middle and right ends of the second vent 303, which are respectively arranged corresponding to the second mounting holes 116 on the square frame 110.

[0066] Furthermore, in some preferred embodiments, 1, Figure 6 , Figure 7 , Figure 11 and Figure 12 As shown, this application further proposes to eliminate the presence of ultrafine micropores 301 between the folded edges 112 near both ends of the microporous membrane 300 and the inlet frame 110, thus forming a partition region. The partition region refers to the end region where the microporous membrane 300 contacts the frame folded edges 112. This region maintains the integrity of the membrane material through high-frequency welding or folding and pressing. The absence of pores in this region avoids the disruption of material continuity caused by micropores, enhances the structural strength of the membrane edge, and thus disperses mechanical constraint stress.

[0067] Combination Figures 1 to 12As shown, the installation and use principle of the plate-type flexible high-efficiency aerator is as follows: (1) Assembly of plate-shaped microporous aeration unit: Forcefully fit the microporous cylindrical membrane 300 onto the support plate 200 with bolts, and make each bolt pass through the corresponding through hole to complete the assembly of a plate-shaped microporous aeration unit; (2) Assembly of aerator: Bend the two ends of the plate-shaped microporous aeration unit downwards, insert it obliquely into the first slots 112 on both sides of the air inlet frame, and lock it with the corresponding bolt group, so that the air inlet 301 at the bottom of the microporous cylindrical membrane 300 forms a closed ventilation path with the first ventilation hole 201 and the air inlet 104, and complete the assembly of the plate-shaped microporous aeration unit on the air inlet frame 100; (3) Installation of aerator: Install the assembled aerator at the bottom of the aeration tank through the ear plates 132 at its four corners with height-adjustable fasteners, and adjust the height of the aerator. Adjust its height so that the aerator is at a certain height from the bottom of the pool and is installed horizontally. Then, use a high-pressure air pipe to connect the aeration connector 122 and connect the other end to the external air source; (4) Operation of the aerator: Open the valve on the aeration connector 122, start the external compressor, and introduce high-pressure air. The gas enters the upper area of ​​the microporous membrane 300 through the air inlet 114 and the air inlet hole at the bottom of the plate-shaped microporous aeration unit through the air inlet pipe 121, and achieves efficient aeration through the distributed ultrafine pores 301; (5) Maintenance of the aerator: When it is necessary to maintain or replace the damaged microporous membrane 300 or support plate 200, remove the fasteners. The middle part of the plate-shaped microporous aeration unit arches upward under the elastic force of the support plate 200 itself, or use an external tool such as a flathead screwdriver to pry up the middle part and remove the plate-shaped microporous aeration unit. Only the damaged parts need to be replaced.

[0068] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
