Abstract
Description
Technical Field
[0001] The embodiments of this utility model relate to the field of aerator technology, specifically to tubular aerators. Background Technology
[0002] As a commonly used oxygen supply device in the wastewater treatment industry, the aerator uses a blower to deliver air through an air pipeline to the aerator laid at the bottom of the tank. Finally, the compressed air is dispersed and escaped in the form of bubbles, dissolving oxygen into the water at the gas-liquid interface and oxygenating the water.
[0003] After prolonged use, aeration pipes are prone to blockage at their aeration ports, leading to reduced aeration efficiency and affecting dissolved oxygen levels in the water. Currently, high-pressure water flushing is commonly used, where a high-pressure water gun is aimed at the aeration holes or interfaces of the aeration pipe, using the impact force of the water flow to flush out the blockages. However, this method requires stopping the machine and lowering the water level so that the aeration pipe is exposed above the water surface, and then manually connecting the high-pressure water gun, making the maintenance process rather cumbersome. Utility Model Content
[0004] To overcome the above-mentioned defects, the embodiments of this utility model provide a tubular aerator, which solves the technical problems in the related technology that the aeration pipe nozzles are easily blocked, and the method of using high-pressure water to flush requires stopping the machine and lowering the water level so that the aeration pipe is exposed above the water surface, and manually connecting the high-pressure water gun, which makes the maintenance steps cumbersome.
[0005] According to one aspect, at least one embodiment of the present invention provides a tubular aerator, comprising: An aeration tube body, wherein a plurality of aeration ports are provided on the outer surface of the aeration tube body; The nozzle is slidably fitted to the aeration pipe body and extends through the aeration port; Several unblocking cores are provided on the inner wall of the aeration pipe and are respectively located in several aeration ports. The unblocking cores are used to unblock the nozzle. An air passage gap is formed between the outer peripheral wall of the unblocking core and the inner peripheral wall of the aeration port. The inner diameter of the nozzle is not greater than the diameter of the unblocking core, so that after the nozzle slides into the aeration pipe, the unblocking core can pass through the inside of the nozzle.
[0006] For example, in at least one embodiment of the present invention, a tubular aerator is provided, wherein a support rod frame is provided on the inner wall of the aeration tube, a plurality of aeration ports are arranged around the support rod frame, and a plurality of unblocking cores are provided on the support rod frame.
[0007] For example, in at least one embodiment of the present invention, a tubular aerator is provided in which the nozzle is arranged in a direction perpendicular to the axis of the aeration tube body, and the nozzle is divided into a contraction section and a uniform section connected in sequence in a direction away from the axis of the aeration tube body, wherein the maximum diameter of the contraction section is not greater than the diameter of the unblocking core.
[0008] For example, in at least one embodiment of the present invention, the tubular aerator has a staghorn cone as the unblocking core, the cross-sectional area of which gradually decreases along the direction away from the axis of the aeration tube, and the minimum diameter of the contraction section is not greater than the maximum diameter of the unblocking core.
[0009] For example, in at least one embodiment of the present invention, the tubular aerator has an elliptical cross-section, or the two sides of the aeration tube are aeration planes, and the aeration ports are provided on the aeration planes.
[0010] For example, at least one embodiment of the present invention provides a tubular aerator, wherein one end of the aeration tube is a constricted air inlet end for pressurized air intake.
[0011] For example, in at least one embodiment of the present invention, a tubular aerator is provided, wherein a mounting block for connecting an air inlet pipe is detachably provided on the constricted air inlet end, and the mounting block has an air guiding channel for guiding air into the aeration tube.
[0012] For example, in at least one embodiment of the present invention, a tubular aerator is provided, wherein the mounting block is Y-shaped and the mounting block also has a mounting part for connecting an air inlet pipe, and the air guide channel passes through the mounting part so that air can be introduced through the air guide channel.
[0013] For example, at least one embodiment of the present invention provides a tubular aerator, wherein there are two aeration tubes, both of which are arc-shaped and symmetrically arranged, and both ends of the two mounting parts have locking parts, and the locking parts at the same end of the two mounting parts can be combined to form a T-shaped part, and further includes: A quick-release sleeve is fitted onto the T-shaped part and is used to connect the two aeration tubes to the air inlet pipe.
[0014] The beneficial effects of the embodiments of this utility model are as follows: The aeration pipe is equipped with aeration ports, and an internal unblocking core is installed corresponding to each aeration port. When the aeration pipe is working, air passes through the air gap between the outer peripheral wall of the unblocking core and the inner peripheral wall of the aeration port, forming bubbles that escape for aeration. Because of the unblocking core, even if a small amount of impurities enters the aeration port, it is unlikely to cause complete blockage, as impurities are unlikely to accumulate in large quantities within the aeration port where the core occupies the majority of the space, thus reducing the possibility of aeration port blockage.
[0015] The nozzle slides into the aeration pipe and passes through the aeration port. Its inner diameter is no larger than the diameter of the unclogging core. When maintenance and unclogging of the aeration pipe are required, the nozzle can be slid into the aeration pipe. Since the unclogging core can pass through the inside of the nozzle, it can clean the inner wall of the nozzle during the sliding process. At the same time, the nozzle can also push out or disperse any impurities that may be present in the aeration port, thus unclogging the aeration port. This method eliminates the need to expose the aeration pipe above the water surface, unlike traditional high-pressure water flushing, allowing for direct unclogging operations underwater.
[0016] Traditional high-pressure water flushing requires shutting down the system, lowering the water level, and manual connection of the high-pressure water gun, making the process cumbersome. In contrast, this tubular aerator, through the cooperation of the spray nozzle and the unblocking core, allows for maintenance without stopping the wastewater treatment system or lowering the water level. Workers can control the spray nozzle to slide within the aeration pipe from outside the tank using a specific device, and use the unblocking core to clear the aeration ports. This avoids complex shutdown, drainage, and manual underwater operations, greatly simplifying the maintenance process, improving efficiency, and reducing costs and risks. Attached Figure Description

[0026] like Figures 1-6 As shown, a tubular aerator according to one embodiment of the present invention is illustrated, comprising: Aeration pipe body 1, wherein a plurality of aeration ports 101 are provided on the outer surface of the aeration pipe body 1; The nozzle 2 is slidably fitted to the aeration pipe body 1 and passes through the aeration port 101; Several unblocking cores 3 are provided on the inner wall of the aeration pipe 1 and are respectively located in the aeration ports 101. The unblocking cores 3 are used to unblock the spray pipe 2. An air passage gap 4 is formed between the outer peripheral wall of the unblocking core 3 and the inner peripheral wall of the aeration port 101. The inner diameter of the nozzle 2 is not greater than the diameter of the unblocking core 3, so that after the nozzle 2 slides into the aeration pipe 1, the unblocking core 3 can pass through the inside of the nozzle 2.
[0027] By using the unblocking core 3 to occupy the main space inside the aeration port 101, the accumulation of impurities is reduced, and the possibility of blockage is lowered. The nozzle 2 works in conjunction with the unblocking core 3 to slide underwater to unblock the aeration port 101. This eliminates the need to stop the machine, lower the water level, or manually connect the high-pressure water gun, simplifying maintenance steps, improving maintenance efficiency, and reducing costs and risks.
[0028] The inner wall of the aeration pipe 1 is provided with a support rod frame 5, and a number of aeration ports 101 are arranged around the support rod frame 5. A number of unblocking cores 3 are all provided on the support rod frame 5.
[0029] The support frame 5 provides a stable mounting carrier for the unblocking core 3, ensuring that its position is fixed within the aeration port 101, preventing displacement due to airflow impact, ensuring the stability of the air passage gap 4, and improving the overall structural stability.
[0030] The nozzle 2 is arranged in a direction perpendicular to the axis of the aeration pipe 1. The nozzle 2 is divided into a contraction section 201 and a uniform section 202 connected in sequence in a direction away from the axis of the aeration pipe 1. The maximum diameter of the contraction section 201 is not greater than the diameter of the unblocking core 3.
[0031] The constriction section 201 is designed to facilitate smoother cooperation between the nozzle 2 and the unblocking core 3, reducing resistance during the sliding process. At the same time, the uniform section 202 ensures the overall structural strength of the nozzle 2 and improves the smoothness of the unblocking operation.
[0032] The unblocking core 3 is a flexible frustum block. The cross-sectional area of the flexible frustum block gradually decreases along the direction away from the axis of the aeration pipe 1, and the minimum diameter of the contraction section 201 is not greater than the maximum diameter of the unblocking core 3.
[0033] The flexible material allows the unblocking core 3 to fit more closely to the nozzle 2 when in contact, improving the cleaning effect on the inner wall of the nozzle 2; the cone shape combined with the constriction section 201 further reduces sliding resistance, while enhancing the ability to push out or disperse impurities in the aeration port 101.
[0034] The aeration pipe 1 has an elliptical cross-section, or the two sides of the aeration pipe 1 are aeration planes 102, and the aeration planes 102 are provided with aeration ports 101.
[0035] The elliptical cross-section or aeration plane 102 design increases the installation area and layout rationality of the aeration port 101, improves aeration efficiency, and makes the placement of the aeration pipe 1 at the bottom of the pool more stable.
[0036] One end of the aeration tube 1 is a constricted air inlet end 103 for pressurized air intake.
[0037] The constricted air inlet 103 can pressurize the incoming air, making the bubbles formed when the air escapes from the air gap 4 smaller and more evenly dispersed, thereby improving oxygen dissolution efficiency and enhancing aeration effect.
[0038] The contraction air inlet end 103 is detachably provided with a mounting block 6 for connecting the air inlet pipe, and the mounting block 6 has an air guiding channel 601 for guiding air into the aeration pipe body 1.
[0039] The detachable mounting block 6 facilitates the connection and disassembly of the aeration pipe body 1 and the air inlet pipe, making it convenient for the installation, maintenance and replacement of the equipment; the air guide channel 601 ensures smooth air intake and reduces airflow loss.
[0040] The mounting block 6 is Y-shaped and also has a mounting part 602 for connecting the air intake pipe. The air guide channel 601 passes through the mounting part 602 so that the air intake can pass through the air guide channel 601.
[0041] The Y-shaped design allows the mounting block 6 to connect to the intake pipe more securely. The mounting part 602 enhances the sealing and stability of the connection. The air guide channel 601 runs through the mounting part 602 to ensure a smooth air intake path and improve air intake efficiency.
[0042] The aeration pipe body 1 comprises two parts, both of which are arc-shaped and symmetrically arranged. Each of the two mounting parts 602 has a locking part 603 at both ends. The locking parts 603 at the same end of the two mounting parts 602 can be combined to form a T-shaped part 7. The system also includes: Quick-release sleeve 8, which is sleeved on the T-shaped part 7 and is used to connect the two aeration pipe bodies 1 to the air inlet pipe.
[0043] The two aeration pipes 1 increase the aeration coverage area; the arc-shaped mounting part 602 and the T-shaped part 7, together with the quick-release sleeve 8, enable the two aeration pipes 1 to be quickly connected and disconnected from the air inlet pipe, simplifying the installation and maintenance process and improving the assembly flexibility of the equipment.
[0044] Specific structure: Aeration ports 101 are evenly distributed on the outer surface of the aeration tube body 1, serving as channels for gas escape. If the aeration tube body 1 has an elliptical cross-section or aeration planes 102 on both sides, the aeration ports 101 are concentrated in these areas, forming an orderly aeration layout.
[0045] Aeration tube 1 and contracted air inlet 103: The contracted air inlet 103 is located at one end of the aeration tube 1 and is in a contracted shape. It is the inlet for air to enter the aeration tube 1. Its structural design is directly connected to the subsequent mounting block 6 to form an air intake passage.
[0046] Aeration port 101 and unblocking core 3: The unblocking core 3 is embedded in the aeration port 101 in a one-to-one correspondence. An air passage gap 4 is reserved between its outer peripheral wall and the inner peripheral wall of the aeration port 101. This ensures that air can escape through the gap to complete aeration, while the core occupies space to reduce clogging. If a support rod 5 is provided, the unblocking core 3 is fixed on the support rod 5, and the support rod 5 is connected to the inner wall of the aeration pipe 1 to form a stable support structure.
[0047] The nozzle 2, aeration tube 1, and unclogging core 3: The nozzle 2 passes through the aeration port 101 and slides in conjunction with the aeration tube 1, allowing it to slide along the axis of the aeration tube 1 or perpendicularly. Its inner diameter is no larger than the diameter of the unclogging core 3, and it is divided into a contraction section 201 and a uniform section 202. The contraction section 201 is adapted to the unclogging core 3, especially the flexible frustum block, to ensure that the unclogging core 3 can pass through the inside of the nozzle 2 during sliding, achieving mutual cleaning.
[0048] The constricted air inlet end 103 and the mounting block 6: The mounting block 6 is detachably mounted on the constricted air inlet end 103, and its internal air guide channel 601 is connected to the constricted air inlet end 103 to guide air from the external air inlet pipe into the aeration pipe body 1. In the Y-shaped structure of the mounting block 6, the mounting part 602 is used to connect the air inlet pipe, and the air guide channel 601 passes through the mounting part 602 to form a complete air inlet path.
[0049] Mounting block 6 and multi-pipe connection structure: When there are two aeration pipes 1, the two mounting parts 602 are symmetrically arc-shaped, and the locking parts 603 at both ends are correspondingly combined to form a T-shaped part 7. The quick-release sleeve 8 is fitted on the T-shaped part 7 to fix the two aeration pipes 1 to the same air inlet pipe, realize multi-pipe coordinated aeration, and facilitate quick disassembly and assembly.
[0050] Working principle: The working principle of tubular aerator mainly includes two aspects: aeration and oxygen supply, and anti-clogging and unblocking. All components work together to achieve efficient and stable oxygen supply for sewage treatment and convenient maintenance.
[0051] During the aeration and oxygen supply process, external air is delivered to the air inlet pipe by a blower and enters the constricted air inlet end 103 of the aeration pipe body 1 through the air guide channel 601 of the mounting block 6. The constriction structure pressurizes the air, increasing its flow rate and pressure. The pressurized air flows inside the aeration pipe body 1 and finally diffuses out through the air gap 4 formed between the unblocking core 3 and the inner wall of the aeration port 101. Due to the gap limitation, the air is divided into tiny bubbles, increasing the gas-liquid contact area. During the rise of the bubbles, oxygen is transferred to the water at the gas-liquid interface, achieving oxygenation. If the aeration pipe body 1 has an elliptical cross section or is equipped with an aeration plane 102, the distribution of the aeration ports 101 is more reasonable, which can further improve the uniformity of aeration and the oxygen dissolution efficiency.
[0052] During the anti-clogging and unblocking process, in daily use, the unblocking core 3 is located inside the aeration port 101, occupying the main space and reducing the accumulation of impurities. At the same time, the airflow continuously flushes the air passage gap 4, reducing the adhesion of impurities and reducing blockage from the source. When a minor blockage occurs, the nozzle 2, which slides through the aeration port 101 and slides in cooperation with the aeration pipe body 1, is used for cleaning. Since the inner diameter of the nozzle 2 is not greater than the diameter of the unblocking core 3, and its constriction section 201 is adapted to the unblocking core 3 (especially the flexible frustum block), the unblocking core 3 can pass through the inside of the nozzle 2 during sliding, scraping and cleaning the inner wall of the nozzle 2. The nozzle 2 simultaneously pushes out or disperses the blockage impurities in the aeration port 101, restoring the air passage gap 4 to be unobstructed. This process does not require stopping the machine or lowering the water level and can be completed directly underwater.
[0053] In addition, the support rod frame 5 fixes the position of the unblocking core 3 to ensure the stability of the air passage gap 4; the Y-shaped structure of the mounting block 6 and the quick-release sleeve 8 cooperate with the T-shaped part 7 to ensure that the connection between the aeration pipe body 1 and the air inlet pipe is firm and easy to install and remove, ensuring that the air inlet passage is unobstructed and providing support for the overall working process.
