Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a suspended aeration system. Background Technology

[0002] In the field of wastewater treatment, aeration components, as key oxygenation equipment, directly affect treatment efficiency and energy consumption. Currently, the mainstream aeration devices are mainly divided into three categories: aeration pipes, aeration discs, and plate aerators. All three are installed at the bottom of the tank. Since the density of these materials is close to 1, they are subject to significant buoyancy during the aeration process, requiring substantial investment to fix them in place. Traditional aeration systems not only increase engineering investment but also waste installation time.

[0003] A utility model patent with publication number CN220519986U discloses an aeration filler hoisting system. This system includes a support frame, a filler device, an aeration device, and a lifting device. The support frame includes a filler support and an aeration support, which are connected and located above the aeration support. The filler device is detachably connected within the filler support and configured for installing filler. The aeration device is detachably connected within the aeration support and configured to aerate from bottom to top along the axial direction of the filler device. The lifting device is connected to the top of the support frame and configured for lifting the support frame. This system, through its synergistic design of aeration discs and packing material, and its liftable structure, significantly outperforms traditional aeration devices in terms of oxygen utilization, maintenance convenience, and anti-clogging capabilities. However, because the system contains various materials (packing support, biological packing material, and aeration system) distributed throughout its space from top to bottom, and the packing material becomes covered with a large amount of biological sludge after normal operation, the installation and lifting of this system must rely on tools such as cranes, gantry cranes, and electric hoists. Therefore, it is unsuitable for small to medium-sized scenarios where only personnel can access the system. Furthermore, the high maintenance costs of the aforementioned aeration packing material lifting system result in significant investment costs and limited versatility. Utility Model Content

[0004] The main purpose of this utility model is to provide a suspended aeration system, which aims to solve the technical problem of the lack of versatility of existing aeration systems.

[0005] To achieve the above objectives, this utility model provides a suspended aeration system, the system comprising at least one aeration component suspended and installed in the pool body;

[0006] Each aeration component includes a horizontal air distribution pipe and corresponding vertical pipes connected to both ends of the horizontal air distribution pipe;

[0007] One or two risers connected to the same horizontal gas distribution pipe are sealed to the gas delivery pipe used to transport the gas source.

[0008] Each air distribution pipe has multiple aeration elements connected to different areas, and each air distribution pipe is also connected to a reinforcing member so that the center of gravity of the aeration assembly is located directly below the geometric center. In the working state, the gravity of the system is greater than the buoyancy of the system.

[0009] Optionally, each aeration component is suspended within the tank via a hoisting device.

[0010] Optionally, each lifting component includes a first hook, a second hook, and a sling connecting the corresponding first hook and second hook. Each first hook is fixed to the pool wall or to the lifting beam above the pool, and each second hook is fixed to the riser and located above the center of gravity of the aeration system.

[0011] Optionally, each lifting component includes a first hook located on the riser and a first hanging ring corresponding to the first hook on each riser. The first hanging ring is fixed to the pool wall or to the lifting beam above the pool.

[0012] Alternatively, each lifting component includes a second hanging ring located on the riser and a second hook corresponding to the second hanging ring on each riser, the second hook being fixed to the pool wall or to the lifting beam above the pool.

[0013] Optionally, the gas pipeline and the connected riser are connected in series with a flexible connector.

[0014] Optionally, each aeration element is symmetrically connected to the corresponding air distribution horizontal pipe.

[0015] Optionally, the cross-section of each air distribution tube can be circular, elliptical, rectangular, or polygonal.

[0016] Optionally, each aeration element is arranged in a straight line, circular or rectangular planar shape along the corresponding air distribution horizontal pipe, and each aeration element is connected to the air distribution horizontal pipe by thread, socket, through or snap.

[0017] Optionally, the reinforcement components are arranged in parallel inside, above, or below the corresponding air distribution horizontal pipe;

[0018] Alternatively, the reinforcement component may be arranged perpendicular to the corresponding air distribution horizontal pipe.

[0019] Optionally, when each aeration element is a microporous aerator, its opening size is 0.05-1.5mm.

[0020] Beneficial effects:

[0021] This system suspends the aeration components within the tank, allowing for better control of the underwater depth and levelness of the aeration elements. It also facilitates easy removal and installation from the tank exterior, enabling installation, replacement, and maintenance without interrupting production. The adjustable height of the suspension components, along with a slight swinging motion similar to a swing in operation, covers a larger tank area, reducing dead zones and preventing sludge accumulation. The swinging motion also reduces biofilm buildup on the aeration element surface, extending maintenance intervals and preventing component tipping due to water flow or air pressure changes, thus extending equipment lifespan. Reinforcing components increase the weight of the aeration components, preventing floating during system operation, and enhance the bending resistance of the corresponding air distribution pipes, preventing bending damage during installation and removal. The system achieves verticality control through a gravity-based self-balancing mechanism, enabling rapid positioning without complex leveling devices. The flexible connection between the system and the air supply pipe allows for leveling adjustments of a single aeration system without being constrained by the air supply pipeline, resulting in greater flexibility, improved installation efficiency, and reduced workload during system maintenance and replacement. The entire system is easy to assemble and low in cost, and can be widely used in small and medium-sized, as well as large and high-load sewage treatment scenarios. Attached Figure Description

[0037] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the implementation methods and with reference to the accompanying drawings. Detailed Implementation

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] It should be noted that all directional indicators (such as up, down, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0040] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0041] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0042] See Figure 1-12 This utility model discloses a schematic diagram of an embodiment of a suspended aeration system, wherein the system includes at least one aeration component 2 suspended within a tank body 1; wherein each aeration component 2 includes an air distribution horizontal pipe 202 and corresponding vertical pipes 201 connected to both ends of the air distribution horizontal pipe 202; one or two vertical pipes 201 connected to the same air distribution horizontal pipe 202 are sealed to an air supply pipe 4 used for conveying air source, there are multiple air supply pipes 4, and each air supply pipe 4 is connected to the connected vertical pipe 201 in series with a flexible connector 205, and multiple air supply pipes 4 are connected to the same main air supply pipe, that is, each air supply pipe 4 is... The main air supply pipe has corresponding branch pipes; each air distribution horizontal pipe 202 has multiple aeration elements 203 connected to different areas, and each air distribution horizontal pipe 202 is also connected to a reinforcing member 204 so that the center of gravity of the aeration component 2 is located directly below the geometric center. In the working state, the gravity of the system is greater than the buoyancy of the system. It can be seen that the reinforcing member 204 can not only increase the gravity of the aeration component 2 and prevent the system from floating in the working state, but also enhance the bending resistance of the corresponding air distribution horizontal pipe 202, preventing bending damage during system loading and unloading. This allows the system to achieve verticality control through a gravity self-balancing mechanism, and can achieve rapid positioning without complex leveling devices. Preferably, the riser 201, the air distribution horizontal pipe 202, and the aeration elements 203 are all hollow structures in the working state.

[0043] Furthermore, each aeration component 2 is suspended within the tank body 1 by a lifting device 3. Specifically, each lifting device 3 includes a first hook 301, a second hook 302, and a sling 303 connecting the corresponding first hook 301 and second hook 302. Each first hook 302 is fixed to the tank wall of the tank body 1, such as... Figure 1 , 3 As shown in Figure 4; or each of the first hooks 301 can also be fixed to the corresponding area of ​​the top plate of the pool body; or, as shown in Figure 4. Figure 2 As shown, the first hook 301 is fixed in the lifting beam 101 above the tank body 1. Simultaneously, each of the second hooks 302 is fixed to the riser 201 and located above the center of gravity of the aeration system. This effectively achieves the hoisting and fixing of the aeration assembly 2.

[0044] Preferably, the center of gravity of each sling 303 is adjusted by adjusting its own length, thereby adjusting the hoisting height of the aeration component 2. Furthermore, in operation, there is a slight swinging motion similar to a swing, which can cover more of the tank area, reduce dead zones in aeration, prevent sludge accumulation in these areas, and reduce biofilm buildup on the surface of the aeration elements, extending maintenance cycles. It also prevents the component from tipping over due to changes in water flow or air pressure, extending equipment lifespan.

[0045] Furthermore, in another embodiment, each lifting component 3 includes a first hook located on the riser 201 and a first hanging ring corresponding to the first hook on each riser 201. The first hanging ring is fixed to the pool wall of the pool body 1 or to the lifting beam 101 above the pool body 1. Figure 11 In the structure shown, the lifting component 3 consists of a first hook located on the riser 201 and a first hanging ring fixed to the tank wall of the tank body 1. The aeration assembly 2 is effectively lifted through the matching design of the hook and hanging ring. Preferably, the first hook can be a rigid structure or a flexible structure, and its length is adjustable to adjust the height of the center of gravity of the aeration assembly 2.

[0046] Furthermore, in another embodiment, each hoisting component 3 includes a second hanging ring located on the riser 201 and a second hook corresponding to the second hanging ring on each riser 201. The second hook is fixed to the pool wall of the pool body 1 or to the hoisting beam 101 above the pool body 1. Figure 12 In the structure shown, the lifting component 3 consists of a second hanging ring located on the riser 201 and a second hook fixed to the pool wall of the pool body 1. Preferably, the second hook can be a rigid structure or a flexible structure, and the length of the second hook itself is adjustable to achieve adjustment of the height of the center of gravity of the aeration component 2.

[0047] Furthermore, the hoisting component 3 connecting the same riser 201 and the pool body 1 can be installed using a single-line hoisting method, such as... Figure 1-6 As shown; a double-line hoisting method can also be used, such as Figure 7-10 .

[0048] Furthermore, when the width of the pool body 1 is large, a hanging beam 101 or a mesh frame is installed at the top of the pool body, and multiple sets of parallel aeration components 2 are used to cover the entire width of the pool body; in addition, each first hook 301 can be fixed to the hanger, guardrail, column, etc. above the pool body 1.

[0049] Furthermore, a flexible connector 205 is connected in series between the gas pipeline 4 and the connected riser 201. Figure 2In the illustrated embodiment, one riser 201 connected to the same horizontal air distribution pipe 202 is sealed to the air supply pipe 4 used for conveying the air source, while the other riser 201 is not connected to the air supply pipe 4. In this case, the riser 201 not connected to the air supply pipe 4 still needs to be connected to the tank body 1 via the lifting component 3. Although no air is being supplied, the overall balance of the aeration assembly 2 still needs to be ensured. Preferably, the flexible connector 205 can be a hose, corrugated pipe, flexible joint, etc.

[0050] Furthermore, each aeration element 203 is symmetrically connected above and / or to the side of the corresponding air distribution horizontal pipe 202. Specifically, as shown... Figure 5-6 As shown, each aeration element 203 is connected above the air distribution horizontal pipe 202, and each aeration element 203 is arranged in a straight line along the corresponding air distribution horizontal pipe 202. And as... Figure 7-8 As shown, each aeration element 203 is connected to the side of the air distribution horizontal pipe 202, the aeration element 203 is perpendicular to the air distribution horizontal pipe 202, and each aeration element 203 is arranged in a rectangular planar shape along the corresponding air distribution horizontal pipe 202. And as shown... Figure 9 As shown, each aeration element 203 is simultaneously connected above and to the side of the air distribution horizontal pipe 202, ultimately resulting in the aeration elements 203 being arranged in a circular planar configuration along the corresponding air distribution horizontal pipe 202. And as shown... Figure 10 As shown, each aeration element 203 is connected to the side of the air distribution horizontal pipe 202. The angle between the aeration element 203 and the air distribution horizontal pipe 202 is an acute angle, and each aeration element 203 is arranged in a rectangular planar shape along the corresponding air distribution horizontal pipe 202.

[0051] Furthermore, the aeration element 203 is connected to the air distribution horizontal pipe 202 via threads, sockets, through connections, or snap-fit ​​connections to accommodate angular changes during the oscillation of the aeration assembly 2. Preferably, when using planar distributed aeration elements 203, at least four sets of lifting components 3 should be provided, such as... Figure 7-10 The lifting component 3 shown is installed using a double-line lifting method to facilitate adjustment of the plane's levelness and aeration effect.

[0052] Furthermore, the cross-section of each air distribution horizontal pipe 202 is circular, elliptical, rectangular, or polygonal, and the height difference of the air outlet surface of different aeration elements 203 on the air distribution horizontal pipe 202 is controlled to be less than 10cm. Figure 1-10 In the embodiments shown, the air distribution horizontal pipe 202 is rectangular. Other circular, elliptical, or polygonal structures are connected in the same way as the rectangular structure, and will not be listed further here.

[0053] Furthermore, the reinforcing member 204 is arranged parallel to the inside, outside, or below the outside of the air distribution horizontal pipe 202. Specifically, as shown... Figure 1-2 As shown, the reinforcement member 204 is arranged below the air distribution horizontal pipe 202; and as shown... Figure 4As shown, the reinforcing member 204 is positioned above the air distribution horizontal pipe 202, and a corresponding support unit connects the reinforcing member 204 and the air distribution horizontal pipe 202. Furthermore, the air distribution horizontal pipe 202 can be uniformly filled with a metallic or non-metallic material with a density greater than water, such as iron blocks, stones, or concrete blocks. Therefore, the reinforcing member can both increase the weight of the aeration component, preventing it from floating during system operation, and enhance the bending resistance of the corresponding air distribution horizontal pipe.

[0054] Furthermore, the reinforcing members 204 are arranged perpendicular to the corresponding air distribution horizontal pipe 202. Specifically, the reinforcing members 204 can be distributed and connected to reinforcing units in different areas of the air distribution horizontal pipe 202, and are arranged symmetrically overall; for example, Figure 3 As shown, the planes of the reinforcing units on both sides are perpendicular to the air distribution horizontal pipe 202, and the central reinforcing unit is vertically fixed to the upper surface of the air distribution horizontal pipe 202. Furthermore, the connection between the reinforcing unit 204 and the air distribution horizontal pipe 202 can be fixed or non-fixed, including welding, bolting, and strut connection, etc. Its main function is to increase the bending resistance of the air distribution horizontal pipe 202, reduce system deformation in large-span pool environments, and ensure the horizontality of the bottom of the aeration system and the uniformity of air output. Preferably, the type of reinforcing unit connected to the same air distribution horizontal pipe 202 is not limited and can be adjusted according to actual process requirements.

[0055] Furthermore, the aeration element 203 includes aerators such as microporous, swirling, and diffused aerators, and is shaped as a disc, plate, or tube. The microporous aerator can be a microporous rubber diaphragm aerator or a microporous polymer material aerator. In actual use, the structure of the aeration element 203 can be adjusted according to actual needs. Preferably, when the aeration element 203 is a microporous aerator, its opening size is 0.05-1.5 mm.

[0056] Furthermore, multiple sets of aeration components 2 are arranged inside the pool body 1, and the preset spacing is 200-2000mm when the flow rate of the mixed liquid in the pool body is low and lower than the siltation flow rate.

[0057] In the above embodiments, those skilled in the art can use existing technology for software control. This utility model only protects the structure of the suspended aeration system and the interconnections between them.

[0058] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
