Description

Technical Field

[0001] This utility model belongs to the field of aeration equipment for biological treatment ponds in sewage treatment, specifically involving an aeration device for treating rural domestic sewage, municipal sewage, and industrial wastewater that can be quickly disassembled and installed without water outage maintenance, and particularly relates to a quick-disassembly and splicing liftable pipe aeration water treatment device. Background Technology

[0002] In aerobic activated sludge wastewater treatment processes, the aeration unit is the core equipment, used to supply oxygen to the water and agitate it. Existing aeration equipment mainly includes bottom-fixed membrane aerators and perforated aerators.

[0003] While existing technologies can achieve fixed installation of aerators in some structural aspects, they have the following significant drawbacks in actual operation and maintenance: Disassembly and assembly rely on water outages: Due to the bottom-fixed installation structure, when the aerator becomes clogged or damaged and requires repair or replacement, the wastewater treatment system must be shut down and the wastewater in the tank emptied before maintenance personnel can enter the bottom of the tank to work. This results in long operation and maintenance cycles, high costs, and seriously affects the continuous operation of the wastewater treatment plant.

[0004] The connection structure is complex and has a low fault tolerance: Traditional connections mostly use rigid pipe welding or flange connections, which have extremely high requirements for installation accuracy, poor deviation compensation ability, and great difficulty in on-site installation alignment.

[0005] Low modularity: The integration of aeration units and pipelines is low. Replacing a single aerator often affects the entire system, sometimes requiring the disassembly of the entire pipeline, resulting in extremely low maintenance efficiency.

[0006] Therefore, developing an aeration device that can be disassembled quickly without water outages, has precise air distribution, and is easy to operate and maintain in a modular manner is a technical problem that the water treatment industry urgently needs to solve. Utility Model Content

[0007] The purpose of this utility model is to provide a quick-release and modular liftable aeration water treatment device to solve the problems of water shutdown and drainage, high operation and maintenance costs, and difficult installation and maintenance of bottom-fixed aeration equipment in the prior art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A quick-release and modular liftable tubular aerated water treatment device includes a main aeration pipe, a ventilation hose, a membrane tube fixing frame, and several tubular aerators. The main aeration pipe is provided with an interface, which is connected to one end of the ventilation hose. The membrane tube fixing frame is provided with a distribution branch pipe joint, and the other end of the air hose is connected to the distribution branch pipe joint. The distribution branch pipe joint is connected to the gas channel inside the membrane tube fixing frame or to the tubular aerator through a pipeline. The membrane tube fixing frame is provided with several pipe clamp seats, and both ends of the tubular aerator are detachably installed on the membrane tube fixing frame through the pipe clamp seats. The membrane tube fixing frame is also connected to a lifting component for lifting the entire device to the water surface.

[0010] Furthermore, the membrane tube fixing frame includes longitudinal beams arranged along the length direction and transverse beams arranged along the width direction, with the longitudinal beams and transverse beams fixedly connected to form a frame structure; the distribution branch pipe joint is disposed on the transverse beam or the longitudinal beam. The frame structure ensures the overall strength of the unit and facilitates overall hoisting.

[0011] Furthermore, the number of pipe clamp seats is adapted to the number of tubular aerators. Each end of a single tubular aerator is inserted into two corresponding pipe clamp seats and locked in place by stainless steel quick-release clamps. A sealing ring is provided inside each pipe clamp seat. This structure enables quick assembly and disassembly of individual aerators without disassembling the entire frame.

[0012] Furthermore, the clamp seat is fixedly mounted on the transverse beam of the membrane tube fixing frame, and the inner wall of the clamp seat has a smooth arc surface structure. The smooth inner wall reduces gas flow resistance and effectively prevents sludge adhesion and deposition.

[0013] Furthermore, the lifting assembly includes a plurality of load-bearing pull rings disposed on the membrane tube fixing frame and steel wire ropes connected to the load-bearing pull rings; the load-bearing pull rings are symmetrically distributed on both sides of the membrane tube fixing frame.

[0014] Furthermore, the wire rope passes through the load-bearing pull ring and is locked by a clamp, and the free end of the wire rope is provided with an anti-slip handle.

[0015] Furthermore, both ends of the ventilation hose are connected to the interface of the main aeration pipe and the distribution branch pipe connector, respectively, via hose connectors; the length of the ventilation hose is greater than the vertical installation distance between the main aeration pipe and the membrane tube fixing frame, to form a connection margin for compensating for installation errors. This flexible connection design not only compensates for installation errors but also allows for maintaining the air path connection or rapid disconnection during lifting.

[0016] Furthermore, the distribution branch pipe joint is welded to the membrane tube fixing frame, and the welding area is provided with an anti-corrosion coating.

[0017] Compared with the prior art, the beneficial effects of this utility model are: With the design of "lifting components + flexible hoses", the membrane tube fixing frame can be lifted to the water surface without emptying the tank; combined with the structure of "pipe clamp seat + quick-release clamp", the replacement of a single tube aerator does not require disassembling the entire frame, which greatly shortens the maintenance time and ensures the continuous and stable operation of the sewage treatment system.

[0018] The flexible connection characteristics of the ventilation hose effectively compensate for errors in the civil construction of the pool and installation misalignment, reducing the difficulty of on-site installation; at the same time, the optional design of the hose clamp spacing and pipe diameter allows it to flexibly adapt to aeration needs of different scales.

[0021] Please see Figure 1-2 This utility model provides a technical solution: a quick-release, modular liftable aeration water treatment device. The structure of this device is "main air control module + liftable modular aeration unit", and the specific connection sequence and structure are as follows: I. Structural Composition (Layered Structure) 1. First level: The system includes the main aeration pipe 1, the ventilation hose 2, and the hose connector 3. Their specific structures and compatibility are as follows: (1) Main aeration pipe 1: The main aeration pipe 1 is made of HDPE material and its pipe diameter is configured as DN150DN200 adjustable specifications. In actual application, the corresponding pipe diameter can be selected and optimized according to the total aeration volume requirement of the aeration system. Several adapter interfaces are pre-set on the outer wall of the main aeration pipe 1 for connecting the subsequent ventilation hose 2.

[0022] (2) Ventilation hose 2: Ventilation hose 2 is made of EPDM material with a nominal diameter of DN25. The length of ventilation hose 2 is adapted to the actual installation distance between the main aeration pipe 1 and the membrane tube fixing frame 4, and both ends of the hose body are reserved for adaptation connection to accommodate installation errors.

[0023] (3) Hose connector 3: Hose connector 3 is a SS304 metal thin tube structure with a nominal diameter of DN20 and a tube length of 10cm-15cm.

[0024] 2. Second level The modular aeration unit can be upgraded and includes a membrane tube fixing frame 4, a distribution branch pipe connector 5, a load-bearing pull ring 9, and a steel wire rope 10. The specific structure is as follows: (1) Membrane tube fixing frame 4: Two SS304 angle steels of model 100×50×5 are set along the length of the membrane tube fixing frame 4, and their length is matched with the length of the tubular aerator 7; two SS304 square tubes of model 100×50 are set along the width, and SS304 steel plates of model 100×50 are welded to both sides of the square tubes respectively, and the steel plates and square tubes are sealed by welding and screw tightening to form a closed structure.

[0025] (2) Distribution branch pipe joint 5: The distribution branch pipe joint 5 adopts SS304 metal short pipe with a DN20 specification and a length of 20mm-30mm; one end of the short pipe is welded to the gas supply main pipe of the membrane tube fixing frame 4 by argon arc welding process. After the welding is completed, the welding area is treated with anti-corrosion coating to improve corrosion resistance.

[0026] (3) Load-bearing pull ring 9 and connection structure: Four load-bearing pull rings 9 are symmetrically arranged on both sides of the upper part of the membrane tube fixing frame 4 in the width direction. The load-bearing pull ring 9 is an M20 specification SS304 nut, and the load-bearing pull ring 9 and the membrane tube fixing frame 4 are fixedly connected by full welding process. Its load-bearing load is not less than twice the weight of the aeration unit itself. The cross connection position of the membrane tube fixing frame 4 in the length direction and the width direction is fixed by tightening with M8 specification stainless steel external hex bolts (with matching flat washers and spring washers), and then the bolt connection area is further reinforced by welding.

[0027] (4) Wire rope 10: 304 stainless steel wire rope 10 with Φ8~Φ10mm is used. Two stainless steel wire rope clamps of appropriate specifications are installed in sequence at the end of the wire rope 10. The clamps are locked symmetrically along the direction of force of the wire rope 10 to realize the reliable connection between the wire rope 10 and the load-bearing pull ring 9. Its length is adapted to the installation water depth of the pool. Its free end is equipped with a non-slip handle structure for easy gripping.

[0028] 3. Third level: The aeration unit includes tubular aerators 7 and pipe clamp seats 6. The tubular aerators 7 are Φ65mm×1000 / 2000mm in size and made of EPDM rubber. The end caps of the aeration membrane tubes are inserted into the grooves of the pipe clamp seats 6, completing the connection between the membrane tubes and the membrane tube fixing brackets 4. The size of the tubular aerators 7 can be selected according to the aeration volume, and their spacing is adjustable from 200-500mm. The number of tubular aerators 7 can be approximately 2-4. The pipe clamp seats 6 are made of corrosion-resistant ABS material with a diameter of Φ65-67mm. The number of pipe clamp seats 6 is adapted to the number of tubular aerators 7; each tubular aerator 7 is equipped with two pipe clamp seats 6.

[0029] II. Connection sequence and main functions 1. Connection between main and branch lines: By evenly opening DN25 interfaces on section 1 of the main aeration pipe, inserting a 2-3mm thick leak-proof rubber gasket at the interface, inserting one end of the DN32 EPDM hose connector 3 into the interface (insertion depth ≥ 2 times the diameter of the thinner pipe), and inserting the other end into the DN25 hose connector 3, and tightening with small stainless steel hose clamps and steel wire.

[0030] 2. Connection between branch and module: Insert the other end of the ventilation hose 2 into the distribution branch pipe joint 5 set in the upper middle part of the membrane tube fixing frame 4 in the width direction, and use the hose clamp to achieve a sealed connection. The ventilation hose 2 elastically compensates for installation deviation.

[0031] 3. Module and aeration unit connection: Insert both ends of the tubular aerator 7 into the pipe clamp seat 6 of the crossbeam of the membrane tube fixing frame 4, and fasten the stainless steel quick-release clamp 8. The O-ring seal built into the pipe clamp seat 6 is used to achieve a seal.

[0032] 4. Liftable structural connection: After the steel wire rope 10 is threaded through the load-bearing pull ring 9 on the membrane tube fixing frame 4, one or two operators can simultaneously lift the steel wire rope 10 within the range of human load by holding the non-slip handle, so as to lift the underwater membrane tube fixing frame 4 to the surface.

[0033] 5. Structural Implementation of Core Functions Water-interruption-free lifting function: This aeration unit is equipped with a lifting connection structure consisting of a frame load-bearing pull ring 9 and a stainless steel wire rope 10, which can realize the overall or single-unit lifting operation of the modular aeration unit. By threading the load-bearing pull ring 9 through the wire rope 10 and locking it with double clamps, the operator can lift the unit above the water surface from the pool side without stopping the operation of the sewage treatment system. The matching EPDM material air hose 2 has excellent flexibility. During the lifting process, the air passage can be temporarily kept open according to the operation needs, or the air passage can be quickly disconnected through the quick-release structure, which not only ensures the smoothness of the lifting operation, but also avoids the loss of treatment efficiency caused by water interruption.

[0034] Quick disassembly function: (1) Single tube quick disassembly: Loosen the stainless steel quick-release clamp 8 on the pipe clamp seat 6 on the membrane tube fixing frame 4, and you can directly take out a single tube aerator 7 without disassembling the entire unit frame, which is convenient for single tube maintenance or replacement; (2) Unit quick disassembly: Disconnect the quick-tightening nut at the end of the ventilation hose 2, and the entire modular aeration unit can be separated from the main air control module, realizing the individual disassembly of the unit, which greatly reduces the complexity and time consumption of maintenance operations.

[0035] High-efficiency air distribution function: The hierarchical air path design of "main aeration pipe 1 → air hose 2 → membrane tube fixing bracket 4 built-in air path → tubular aerator 7" forms a continuous and unobstructed gas flow channel; at the same time, the inner wall of the pipe clamp seat 6 is smoothed to reduce local resistance during gas flow. Actual tests show that compared with the traditional structure, the gas flow resistance of this design is reduced by more than 20%, and the smooth inner wall can avoid sludge adhesion and deposition, effectively preventing sludge accumulation and blockage of the air path, and ensuring stable aeration efficiency.

[0036] III. Main Advantages 1. Significantly improved operation and maintenance efficiency: Relying on the single-pipe quick-disassembly structure and water-stop-free lifting design, the operation and maintenance efficiency of this aeration unit is greatly optimized: the replacement time of a single tube aerator 7 is ≤30s, without the need to disassemble the overall frame; the complete disassembly and assembly time of a single modular unit is ≤2min, and the entire process does not require stopping the operation of the sewage treatment system. Compared with the operation and maintenance mode of traditional aeration equipment, the overall operation and maintenance time is reduced by more than 80%, effectively reducing the impact of operation and maintenance on treatment efficiency.

[0037] 2. Enhanced adaptability to multiple scenarios: (1) Installation deviation compensation: EPDM material flexible ventilation hose 2 is adopted. Its excellent flexibility can effectively compensate for the construction error of the pool and the installation alignment deviation, reducing the difficulty of on-site installation; (2) Size and working condition adaptation: The spacing of the pipe clamp seat 6 of the membrane tube fixing frame 4 is designed to be adjustable, which can be flexibly adjusted according to the length and width of different pools. At the same time, the main aeration pipe 1 is equipped with a DN150~DN200 optional pipe diameter, which can adapt to the aeration volume requirements of different treatment scales and improve the versatility of the equipment.

[0038] 3. Reduced overall operating costs: (1) Optimized spare parts costs: The modular integrated design enables the standardization and universality of various functional components (tubular aerator 7, air hose 2, hose connector 3), reducing the types and quantities of special spare parts in stock and reducing spare parts reserve costs; (2) Saved operation and maintenance costs: The water-free operation and maintenance mode avoids the traditional operation and maintenance process of draining and filling the pool, which greatly saves water resources consumption and related energy costs; (3) Extended service life: The core structures such as membrane tube fixing frame 4, load-bearing pull ring 9, hose connector 3 are all made of SS304 stainless steel, which has excellent resistance to sewage corrosion, extending the overall service life of the equipment and reducing the frequency of equipment replacement and long-term investment costs.
