Description

Technical Field

[0001] The utility model relates to the field of aerators, in particular to an aerator used for sewage treatment. Background Art

[0002] The cyclone aerator is a highly efficient sewage treatment equipment. Its principle is to use the rotor to generate strong turbulence to disperse and dissolve the gas in the water. The main components of this aerator include an aeration tank, a cyclone and an air intake device. Inside the cyclone, the water forms anisotropic turbulence under the action of the cyclone, which helps the intake bubbles to fully contact and diffuse with the water, thereby enhancing the solubility of the gas and improving the oxidation of the water.

[0003] The existing cyclone aerator relies on multiple turbine blades and rods to finely cut the high-pressure air during operation. However, in this link, the impact force of the high-pressure airflow on the turbine blades and rods is quite significant, causing the aerator to vibrate greatly. The connection between the aerator and the air inlet pipe, as the main connection point, is particularly sensitive to vibration. Unfortunately, the commonly used connection method is to connect through a hard flange. When vibration occurs, the connection part will be subjected to huge stress, and the traditional flange connection structure cannot effectively alleviate the impact caused by this vibration. Therefore, the connection is often damaged, which seriously affects the service life of the aerator. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an aerator for sewage treatment to solve the technical problem that the traditional flange connection structure fails to effectively offset the vibration force, resulting in a higher frequency of damage at the connection and reducing the service life of the aerator.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an aerator for sewage treatment, comprising an aerator body and an air duct, an energy absorbing mechanism is arranged between the aerator body and the air duct, the energy absorbing mechanism comprises a connecting seat, an energy absorbing layer is arranged on one side of the connecting seat, the connecting seat is fixedly connected to the energy absorbing layer through a first flange, the other end of the energy absorbing layer is connected to the air duct through a second flange, and a supporting mechanism is arranged at the bottom of the aerator body.

[0006] By adopting the above technical solution, the vibration force generated by the collision of high-pressure gas can be effectively absorbed and released. This material has good elasticity and deformation recovery ability. When subjected to external force, it can absorb and disperse the impact force through deformation, thereby reducing the impact of vibration on the equipment connection.

[0007] Furthermore, the connecting seat, the first flange, the second flange and the air guide pipe are connected through a reinforcement rod, and the reinforcement rod is used to provide additional supporting force.

[0008] By adopting the above technical solution, the reinforcement rod is made of rubber material, which enhances the integrity and stability of the connection structure. The reinforcement rod serves as an additional supporting element, providing stronger supporting force for these connecting parts to prevent loosening or breakage under high-pressure airflow and working vibration.

[0009] Furthermore, the energy absorbing layer is made of rubber, which is used to absorb the vibration stress generated at the connection between the aerator body and the air guide pipe.

[0010] By adopting the above technical solution, the rubber material has good elasticity and toughness, and can effectively absorb the vibration stress generated at the connection between the aerator body and the air guide pipe. This material can deform when subjected to external force, thereby converting the vibration energy into heat energy and consuming it, reducing the impact on the connection.

[0011] Furthermore, the supporting mechanism is used for installation and connection between the aerator body and the external medium, and provides additional buffering and energy absorbing effects.

[0012] By adopting the above technical solution, a stable installation connection between the aerator body and the external medium is ensured, providing a stable foundation for the entire aerator. This stable connection ensures the reliability and safety of the aerator during operation.

[0013] Furthermore, the support mechanism includes a support plate and a bottom plate, and a buffer layer and a connecting rod are arranged between the support plate and the bottom plate.

[0014] By adopting the above technical solution, a stable supporting foundation is provided for the aerator body, the support plate directly supports the aerator body, and the bottom plate is in contact with the external medium, thereby ensuring the stable installation of the equipment.

[0015] Furthermore, the buffer layer is made of rubber and is used to absorb the vibration force generated at the connection between the aerator body and the external medium.

[0016] By adopting the above technical solution, the aerator has excellent elasticity and vibration absorption capacity. When vibration force is generated at the connection between the aerator body and the external medium, the rubber buffer layer can effectively absorb these vibrations and reduce the impact of vibration on the equipment structure.

[0017] Furthermore, mounting ears are provided on both sides of the aerator body, and a stabilizing rod is provided between the mounting ears and the air guide pipe.

[0018] By adopting the above technical solution, convenience is provided for the installation and fixation of the equipment. The mounting ears serve as connection points, so that the aerator can be firmly installed and connected to the stabilizing rod, thereby ensuring the stability and safety of the equipment.

[0019] Furthermore, the stabilizing rod is in a "U"-shaped structure, and is used to stabilize the aerator body and the air guide tube.

[0020] By adopting the above technical solution, the shape of the "U"-shaped structure enables it to fit tightly between the aerator body and the air guide pipe, providing a stable support.

[0021] Furthermore, an aeration mechanism is arranged inside the aerator body, and the aeration mechanism includes an aeration cylinder, and needles and spiral blades are arranged on the outside of the aeration cylinder.

[0022] By adopting the above technical solution, the aeration mechanism can achieve efficient gas dispersion and dissolution process, which is crucial for the aeration process in sewage treatment.

[0023] Furthermore, the needles are provided in plurality and arranged in an equidistant spiral structure, and a top cover is detachably connected to the top of the aerator body.

[0024] By adopting the above technical solution, the dispersion and dissolution of gas can be promoted more comprehensively and the aeration efficiency can be improved. The setting of multiple needles increases the contact points between gas and sewage, while the arrangement of equidistant spiral structures ensures that the gas can be evenly distributed into the sewage.

[0025] In summary, the utility model mainly has the following beneficial effects:

[0026] 1. The utility model uses an energy-absorbing mechanism, and the application of the rubber energy-absorbing layer in the aerator plays a vital role. Since the collision between the high-pressure gas and the internal structure during the aeration process will generate a strong vibration force, if there is no appropriate buffer mechanism, this vibration force is likely to cause damage to the key connection parts of the equipment. The rubber energy-absorbing layer effectively absorbs and disperses these vibration forces through its unique elasticity and deformation ability, thereby protecting the connection between the aerator body and the air guide pipe, reducing the wear and failure rate of the equipment, and at the same time, not only enhancing the stability and durability of the equipment, but also significantly reducing the maintenance frequency of this part. The reduction in the number of maintenance times means that the equipment runs more continuously, with higher efficiency and lower maintenance costs, which is crucial for sewage treatment systems that need to run continuously for a long time. Therefore, the rubber energy-absorbing layer not only improves the convenience of the aerator, but also provides a strong guarantee for its long-term stable operation;

[0027] 2. The utility model provides a supporting mechanism, and the vibration force generated during the aeration process will be transmitted to the aerator body. This is an inevitable phenomenon caused by the operation of the equipment. However, by providing a buffer layer made of rubber material, these vibration forces are effectively absorbed, thereby reducing potential damage to the equipment structure. At the same time, this buffer layer replaces the fixed connection with the external ground in the traditional structure. This alternative method not only provides better vibration absorption effect, but also avoids stress concentration and possible fracture problems caused by fixed connection. Therefore, the application of the rubber buffer layer significantly improves the service life of the aerator, reduces maintenance costs, and enhances the overall performance and reliability of the equipment.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0034] The following describes an embodiment of the utility model based on its overall structure. Embodiment 1:

[0035] An aerator for sewage treatment, such as Figure 1-Figure 4As shown, it includes an aerator body 1 and an air duct 2, an energy absorbing mechanism 5 is arranged between the aerator body 1 and the air duct 2, the energy absorbing mechanism 5 includes a connecting seat 501, an energy absorbing layer 504 is arranged on one side of the connecting seat 501, the connecting seat 501 is fixedly connected to the energy absorbing layer 504 through a first flange 502, and the other end of the energy absorbing layer 504 is connected to the air duct 2 through a second flange 503. A supporting mechanism 3 is arranged at the bottom of the aerator body 1, which can effectively absorb and release the vibration force generated by the collision of high-pressure gas. This material has good elasticity and deformation recovery ability. When subjected to external force, it can absorb and disperse the impact force through deformation, thereby reducing the impact of vibration on the connection of the equipment. At the same time, the protectiveness of the connection between the aerator body 1 and the air duct 2 is improved, and the wear and damage risk of the equipment at this position is reduced. Since the energy absorbing layer 504 effectively reduces the vibration force transmitted to the connection, the service life of the equipment can be extended and the maintenance frequency of this position can be reduced.

[0036] See also Figure 1 , Figure 4 The connecting seat 501, the first flange 502, the second flange 503 and the air guide pipe 2 are connected through the reinforcement rod 505. The reinforcement rod 505 is used to provide additional supporting force. The reinforcement rod 505 is made of rubber, which enhances the integrity and stability of the connection structure. The reinforcement rod 505 serves as an additional supporting element to provide stronger supporting force for these connection parts to prevent loosening or breakage under high-pressure airflow and working vibration. At the same time, the use of the reinforcement rod 505 also improves the safety performance of the aerator. During the operation of the aerator, the collision between the high-pressure gas and the internal structure will generate strong vibration and impact force, and the reinforcement rod 505 can effectively disperse these forces to the entire connection structure, reducing the force on a single component, thereby reducing the risk of equipment failure and ensuring the stable operation of the aerator.

[0037] See also Figure 1 , Figure 4 The energy-absorbing layer 504 is made of rubber, which is used to absorb the vibration stress generated at the connection between the aerator body 1 and the air duct 2. The rubber material has good elasticity and toughness, and can effectively absorb the vibration stress generated at the connection between the aerator body 1 and the air duct 2. This material can deform when subjected to external force, thereby converting the vibration energy into heat energy for consumption, reducing the impact on the connection. At the same time, the rubber energy-absorbing layer 504 can also play a buffering role, preventing the connection from loosening or damage caused by vibration, thereby improving the stability and durability of the equipment, not only extending the service life of the aerator, but also reducing the frequency of maintenance and overhaul, and reducing operating costs. Embodiment 2:

[0038] See also Figure 1 , Figure 2 , Figure 3 The support mechanism 3 is used for the installation connection between the aerator body 1 and the external medium, and provides an additional buffering and energy-absorbing effect, ensuring the stable installation connection between the aerator body 1 and the external medium, and providing a stable foundation for the entire aerator. This stable connection ensures the reliability and safety of the aerator during operation. At the same time, the support mechanism 3 also provides an additional buffering and energy-absorbing effect, which means that the vibration and impact force generated during the operation of the aerator will be effectively absorbed and buffered by the support mechanism, thereby reducing damage to the aerator body and external connection components.

[0039] See also Figure 1 , Figure 2 , Figure 3 The support mechanism 3 includes a support plate 301 and a bottom plate 302. A buffer layer 303 and a connecting rod 304 are arranged between the support plate 301 and the bottom plate 302, which provide a stable support foundation for the aerator body 1. The support plate 301 directly supports the aerator body 1, and the bottom plate 302 is in contact with the external medium, ensuring the stable installation of the equipment. At the same time, the buffer layer 303 and the connecting rod 304 arranged between the support plate 301 and the bottom plate 302 play a key buffering and connecting role. The buffer layer 303 can absorb and disperse the vibration and impact force generated when the aerator is working, protecting the equipment from damage. The connecting rod 304 enhances the connection strength between the support plate 301 and the bottom plate 302, ensuring the stability and rigidity of the support mechanism, thereby improving the overall performance and durability of the aerator.

[0040] See also Figure 1 , Figure 2 , Figure 3 The buffer layer 303 is made of rubber and is used to absorb the vibration force generated at the connection between the aerator body 1 and the external medium. It has excellent elasticity and vibration absorption capacity. When vibration force is generated at the connection between the aerator body 1 and the external medium, the rubber buffer layer can effectively absorb these vibrations and reduce the impact of vibration on the equipment structure. At the same time, the use of the rubber buffer layer 303 can also improve the stability and durability of the equipment. By absorbing vibrations, it reduces the wear of key components of the equipment and extends the service life of the equipment. This also reduces the frequency and cost of equipment maintenance and improves overall operational efficiency.

[0041] See also Figure 1 , Figure 2 , Figure 3Mounting ears 6 are provided on both sides of the aerator body 1, and a stabilizing rod 7 is provided between the mounting ears 6 and the air duct 2, which provides convenience for the installation and fixation of the equipment. The mounting ears 6 serve as connection points, so that the aerator can be firmly installed and connected with the stabilizing rod 7, ensuring the stability and safety of the equipment. At the same time, the stabilizing rod 7 provided between the mounting ears 6 and the air duct 2 further enhances the stability of the equipment. The stabilizing rod 7 can effectively reduce the shaking and vibration that may be generated by the equipment during operation, thereby protecting the equipment from damage and extending the service life of the equipment.

[0042] See also Figure 1 , Figure 2 The stabilizing rod 7 is in a "U"-shaped structure, and the stabilizing rod 7 is used to stabilize the aerator body 1 and the air duct 2. The shape of the "U"-shaped structure enables it to fit tightly between the aerator body 1 and the air duct 2, providing a stable support. At the same time, the "U"-shaped stabilizing rod 7 can effectively reduce the relative movement between the aerator body 1 and the air duct 2, enhance the overall stability of the equipment, and help prevent the equipment from being displaced or damaged due to vibration or external force during operation, thereby ensuring the normal operation and service life of the aerator.

[0043] See also Figure 1 , Figure 2 , Figure 3 An aeration mechanism 8 is arranged inside the aerator body 1, and the aeration mechanism 8 includes an aeration cylinder 801. The outer side of the aeration cylinder 801 is provided with a needle 802 and a spiral blade 803. The aeration mechanism 8 can realize an efficient gas dispersion and dissolution process, which is crucial for the aeration link in sewage treatment. At the same time, the needle 802 and the spiral blade 803 on the outer side of the aeration cylinder 801 can further promote the collision, segmentation and refinement of the gas, making the bubbles smaller and more uniform, thereby improving the contact area between the gas and the sewage and the dissolution efficiency.

[0044] See also Figure 1 , Figure 2 , Figure 3 There are multiple needles 802 arranged in an equidistant spiral structure. The top of the aerator body 1 is detachably connected to a top cover 4, which can promote the dispersion and dissolution of the gas more comprehensively and improve the aeration efficiency. The arrangement of multiple needles 802 increases the contact points between the gas and the sewage, and the arrangement of the equidistant spiral structure ensures that the gas can be evenly distributed into the sewage. At the same time, the top of the aerator body 1 is detachably connected to a top cover 4. This design facilitates the maintenance and overhaul of the equipment. When it is necessary to clean or replace the internal parts of the aerator, the top cover 4 can be easily opened for operation, which improves the maintainability and ease of use of the equipment.

[0045] The implementation principle of the utility model is as follows: first, the external Roots blower and the air guide pipe 2 are used to transmit high-pressure gas to the inside of the aerator body 1, and then the high-pressure gas is collided and divided by a plurality of needles 802 and spiral blades 803, so that the gas overflowing from the top cover 4 is changed into a plurality of bubbles. With the continuous infusion of the high-pressure gas, the aeration operation of the sewage is completed;

[0046] During the aeration process, the collision force generated by the collision between the high-pressure gas and the needle 802 and the spiral blade 803 is transmitted to the aerator body 1. At this time, the energy-absorbing layer 504 made of rubber material provided between the aerator body 1 and the air guide tube 2 effectively absorbs and releases this part of the vibration force through the deformation of the energy-absorbing layer 504, thereby improving the protection of the connection between the aerator body 1 and the air guide tube 2, reducing the maintenance frequency of this position, and improving the convenience of using the aerator;

[0047] During the aeration process, the vibration force generated by the operation is transmitted to the aerator body 1, and then the vibration force is absorbed by the rubber buffer layer 303 to replace the fixed connection with the external ground in the traditional structure, thereby increasing the service life of the aerator.

[0048] Parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.
