Description

Technical Field

[0001] This utility model relates to the field of anti-clogging technology for aeration discs, and in particular to an anti-clogging diffuser for aeration discs used in sewage treatment. Background Technology

[0002] In wastewater treatment, aeration is crucial. The main function of aeration is to forcibly introduce air into the wastewater, allowing it to come into contact with oxygen, promoting microbial metabolism, and decomposing organic matter in the wastewater, thereby purifying the water. As a key piece of equipment in the aeration process, the performance of the aeration disc directly affects the aeration effect and wastewater treatment efficiency.

[0003] However, existing aeration discs face numerous challenges in practical applications. With industrial development, wastewater composition is becoming increasingly complex, making the treatment of wastewater with high suspended solids a major problem. Wastewater with high suspended solids contains a large amount of solid particles and colloidal substances, which easily clog the channels of the aeration discs during aeration. Once the channels are clogged, it not only affects the uniformity and efficiency of aeration, leading to a decrease in wastewater treatment effect, but also increases the energy consumption of the aeration system.

[0004] Furthermore, when aeration stops, the pressure of the wastewater causes it to backflow into the micropores of the aeration discs, and residual impurities further exacerbate the clogging. Statistics show that the clogging rate of aeration discs can exceed 60% when treating wastewater with high suspended solids. This not only necessitates frequent replacement of aeration discs, increasing equipment costs, but also requires regular emptying of the water tank for maintenance, consuming significant time and manpower, and greatly increasing the operating costs of wastewater treatment. Therefore, we propose an anti-clogging diffuser for aeration discs in wastewater treatment to address these problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-clogging diffuser for aeration discs in wastewater treatment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A clog-resistant diffuser for wastewater treatment includes a carrier pipe body. An airflow diffusion mechanism is fixed to one side of the carrier pipe body. A rotating rod is rotatably connected to the airflow diffusion mechanism. A connector is fixed to one end of the rotating rod. Four turbine blades are fixed at equal intervals on the circumference of the connector. Four cleaning mechanisms are fixed at equal intervals to one end of the connector. A filter screen is installed at one end of the carrier pipe body. The cleaning mechanisms correspond to the filter screen. A sealing head is threaded to one end of the carrier pipe body. A sealing mechanism is provided on one side of the sealing head.

[0008] Preferably, the airflow diffusion mechanism includes a conical air inlet hood fixed to one side of the body of the carrier tube, one end of the conical air inlet hood is connected to a connecting pipe, and one end of the connecting pipe is connected to a conical air outlet hood.

[0009] Preferably, a fixing plate is fixed between the opposite sidewalls inside the conical vent hood, and one end of the rotating rod of the fixing plate is rotatably connected to the middle of the fixing plate.

[0010] Preferably, the cleaning mechanism includes a guide vane fixed to one side of the connector, and a plurality of brushes are connected to one side of the guide vane.

[0011] Preferably, the sealing mechanism includes a cap connected to one end of the sealing head via a pivot.

[0012] Preferably, the closed head has a threaded through hole in the middle, and one end of the bearing tube body has a plurality of first external threads at equal intervals, and the threaded through hole and the first external threads are screwed together.

[0013] Preferably, the upper end of the bearing tube body is provided with a plurality of second external threads at equal intervals.

[0014] In this invention, when wastewater treatment is required, the carrier pipe body is screwed onto the air outlet end of the aeration disc via a second external thread. When high-pressure gas is transported, it drives the turbine blades to rotate after passing through the airflow diffusion mechanism, enabling the gas to diffuse and accelerate during flow. As the turbine blades rotate, they drive the connector and cleaning mechanism to rotate. The rotation of the turbine blades converts the kinetic energy of the gas into mechanical energy, providing power for the subsequent cleaning mechanism, thereby cleaning impurities on the filter screen and facilitating gas flow. The sealing head on one side can be used selectively as needed. After installation, when high-pressure gas passes through, it drives the cover to open. When the gas stops, the cover closes to further seal the interior, preventing impurities from remaining in the micropores and further reducing the possibility of blockage.

[0015] This utility model has the following advantages:

[0016] 1. The cleaning mechanism is driven by the turbine blades to rotate, which can remove impurities on the filter screen in time, effectively reducing the clogging rate of the aeration disc channels. Even when treating wastewater with high suspended solids, it can ensure the stable operation of the aeration system and improve the wastewater treatment efficiency.

[0017] 2. The bearing pipe body is screwed to the air outlet end of the aeration disc through the second external thread, and the sealing head is screwed to the first external thread at one end of the bearing pipe body through the threaded through hole. The threaded connection makes the disassembly and assembly of the equipment very convenient. There is no need to drain the water tank during maintenance, which greatly reduces maintenance costs and time.

[0018] 3. The design of the airflow diffusion mechanism enables the high-pressure gas to diffuse evenly, improving the uniformity of gas distribution and thus enhancing the aeration effect. At the same time, the anti-clogging function ensures smooth gas flow, further improving aeration efficiency and helping to better achieve the goal of wastewater treatment.

[0019] 4. It reduces the occurrence of channel blockage and sewage backflow, reduces equipment wear and damage, extends the service life of aeration discs and related equipment, reduces the frequency of equipment replacement, and saves costs for sewage treatment;

[0020] In summary, this invention not only effectively reduces the clogging rate of aeration disc channels, but also allows for quick disassembly and assembly, significantly reducing maintenance costs and time. Furthermore, it further improves aeration efficiency, helping to better achieve wastewater treatment goals, extending the service life of aeration discs and related equipment, and reducing the frequency of equipment replacement.

Detailed Implementation

[0028] 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.

[0029] Reference Figure 1-6A clog-resistant diffuser for aeration discs in wastewater treatment includes a support pipe body 12. The support pipe body 12 is made of high-strength, corrosion-resistant stainless steel, which can not only withstand the impact of high-pressure gas, but also be used for a long time in the complex environment of wastewater treatment, ensuring the stability and reliability of the device.

[0030] An airflow diffusion mechanism is fixed on one side inside the bearing tube body 12. A rotating rod 6 is rotatably connected inside the airflow diffusion mechanism. A connector 5 is fixed at one end of the rotating rod 6. Four turbine blades 1 are fixed at equal intervals on the side wall of the connector 5. When high-pressure gas passes through the airflow diffusion mechanism, it will impact the turbine blades 1 and make them rotate. The design of the turbine blades 1 can efficiently convert the kinetic energy of the gas into mechanical energy to provide power for the subsequent cleaning mechanism.

[0031] Four cleaning mechanisms are fixed at equal intervals at one end of the connector 5. A filter screen plate 2 is installed at one end of the bearing pipe body 12. The cleaning mechanisms correspond to the filter screen plate 2. A sealing head 14 is threaded to one end of the bearing pipe body 12. A sealing mechanism is provided on one side of the sealing head 14. Through the coordinated action of the airflow diffusion mechanism, rotation and cleaning mechanism and sealing mechanism, the diffusion and acceleration of gas can be effectively realized, while avoiding the clogging of the filter screen plate and micropores, thus improving the efficiency of sewage treatment and the service life of the aeration disc.

[0032] The airflow diffusion mechanism includes a conical air inlet hood 9 fixed inside one side of the bearing tube body 12. One end of the conical air inlet hood 9 is connected to a connecting pipe 8, and one end of the connecting pipe 8 is connected to a conical air outlet hood 7. The inner wall of the conical air inlet hood 9 is specially polished to reduce the resistance during gas flow and improve the gas entry efficiency. The small opening of the conical air outlet hood 7 faces the gas outlet direction, which enables the gas to diffuse and accelerate when it flows out.

[0033] A fixing plate 10 is fixed between the opposite side walls inside the conical vent 7. One end of the fixing plate rotating rod 6 is rotatably connected to the middle of the fixing plate 10. The fixing plate 10 is made of high-strength plastic material, which not only ensures sufficient strength but also reduces the weight of the entire mechanism and reduces the burden on the bearing tube body 12.

[0034] The cleaning mechanism includes a guide vane 3 fixed to one side of the connector 5. Multiple brushes 4 are connected to one side of the guide vane 3. As the turbine blade 1 rotates, it drives the connector 5 and the cleaning mechanism to rotate. During the rotation, the guide vane 3 can guide the flow direction of the gas. At the same time, the brushes 4 will clean the filter screen 2, remove the impurities on the filter screen 2, and ensure that the gas can pass through the filter screen 2 smoothly, avoiding the blockage of impurities and affecting the flow of gas. The brushes 4 are made of soft and tough material, which can effectively clean impurities without damaging the filter screen 2.

[0035] The sealing mechanism includes a cover 15 connected to one end of the sealing head 14 via a rotating shaft 17. The sealing head 14 has a threaded through hole 16 in the middle. One end of the bearing tube body 12 has multiple first external threads 11 at equal intervals, and the threaded through hole 16 and the first external threads 11 are screwed together. A sealing gasket is also provided at the threaded connection to prevent gas leakage and improve the sealing performance of the device.

[0036] Multiple second external threads 13 are provided at equal intervals on one side of the upper end of the bearing pipe body 12. The size and pitch of the second external threads 13 can be tightly matched with the air outlet end of the aeration disc to ensure the stability of the connection.

[0037] In this utility model, when sewage treatment is required, the carrier pipe body 12 is screwed onto the air outlet end of the aeration disc via the second external thread 13. When high-pressure gas is transported, it drives the turbine blade 1 to rotate after passing through the airflow diffusion mechanism, which enables the gas to diffuse and accelerate during the flow. As the turbine blade 1 rotates, it drives the connector 5 and the cleaning mechanism to rotate. The rotation of the turbine blade converts the kinetic energy of the gas into mechanical energy, providing power for the subsequent cleaning mechanism, thereby cleaning the impurities on the filter screen 2 and facilitating gas flow. The sealing head 14 on one side can be used selectively as needed. After installation, when high-pressure gas passes through, it drives the cover 15 to open. When the gas stops, the cover 15 closes under gravity to further seal the interior, preventing impurities from remaining in the micropores and further reducing the possibility of blockage.

[0038] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
